Introduction
The Internal Revenue Bulletin is the authoritative instrument
of the Commissioner of Internal Revenue for announcing offi-
cial rulings and procedures of the Internal Revenue Service
and for publishing Treasury Decisions, Executive Orders, Tax
Conventions, legislation, court decisions, and other items of
general interest. It is published weekly.
It is the policy of the Service to publish in the Bulletin all sub-
stantive rulings necessary to promote a uniform application
of the tax laws, including all rulings that supersede, revoke,
modify, or amend any of those previously published in the
Bulletin. All published rulings apply retroactively unless other-
wise indicated. Procedures relating solely to matters of inter-
nal management are not published; however, statements of
internal practices and procedures that affect the rights and
duties of taxpayers are published.
Revenue rulings represent the conclusions of the Service
on the application of the law to the pivotal facts stated in
the revenue ruling. In those based on positions taken in rul-
ings to taxpayers or technical advice to Service field offices,
identifying details and information of a confidential nature are
deleted to prevent unwarranted invasions of privacy and to
comply with statutory requirements.
Rulings and procedures reported in the Bulletin do not have the
force and effect of Treasury Department Regulations, but they
may be used as precedents. Unpublished rulings will not be
relied on, used, or cited as precedents by Service personnel in
the disposition of other cases. In applying published rulings and
procedures, the effect of subsequent legislation, regulations,
court decisions, rulings, and procedures must be considered,
and Service personnel and others concerned are cautioned
against reaching the same conclusions in other cases unless
the facts and circumstances are substantially the same.
The Bulletin is divided into four parts as follows:
Part I.—1986 Code.
This part includes rulings and decisions based on provisions
of the Internal Revenue Code of 1986.
Part II.—Treaties and Tax Legislation.
This part is divided into two subparts as follows: Subpart A,
Tax Conventions and Other Related Items, and Subpart B,
Legislation and Related Committee Reports.
Part III.—Administrative, Procedural, and Miscellaneous.
To the extent practicable, pertinent cross references to these
subjects are contained in the other Parts and Subparts. Also
included in this part are Bank Secrecy Act Administrative
Rulings. Bank Secrecy Act Administrative Rulings are issued
by the Department of the Treasury’s Office of the Assistant
Secretary (Enforcement).
Part IV.—Items of General Interest.
This part includes notices of proposed rulemakings, disbar-
ment and suspension lists, and announcements.
The last Bulletin for each month includes a cumulative index
for the matters published during the preceding months. These
monthly indexes are cumulated on a semiannual basis, and are
published in the last Bulletin of each semiannual period.
The contents of this publication are not copyrighted and may be reprinted freely. A citation of the Internal Revenue Bulletin as the source would be appropriate.

Part I
Section 61. Gross Income
Defined
26 CFR 1.61-21: Taxation of Fringe
Benefits
Rev. Rul. 2026-18
For purposes of the taxation of fringe
benefits under section 61 of the Internal
Revenue Code, section 1.61-21(g) of
the Income Tax Regulations provides a
rule for valuing noncommercial flights
on employer-provided aircraft. Section
1.61-21(g)(5) provides an aircraft val-
uation formula to determine the value
of such flights. The value of a flight is
determined under the base aircraft valua-
tion formula (also known as the Standard
Industry Fare Level formula or SIFL)
by multiplying the SIFL cents-per-mile
rates applicable for the period during
which the flight was taken by the appro-
priate aircraft multiple provided in sec-
tion 1.61-21(g)(7) and then adding the
applicable terminal charge. The SIFL
cents-per-mile rates in the formula and
the terminal charge are calculated by the
Department of Transportation (DOT) and
are reviewed semi-annually.
The following chart sets forth the ter-
minal charge and SIFL mileage rates:
Period During Which
Terminal SIFL Mileage
the Flight Is Taken Charge Rates
7/1/26 - 12/31/26 $58.95 Up to 500 miles
= $.3225 per mile
501-1500 miles
= $.2459 per mile
Over 1500 miles
= $.2364 per mile

Bulletin No. 2026–42 491 October 13, 2026
Part III
Extension of Replacement
Period for Livestock Sold
on Account of Drought
Notice 2026-54
SECTION 1. PURPOSE
This notice provides guidance regard-
ing an extension of the replacement period
under § 1033(e) of the Internal Revenue
Code for livestock sold on account of
drought in specified counties.
SECTION 2. BACKGROUND
.01 Nonrecognition of Gain on Invol-
untary Conversion of Livestock. Section
1033(a) generally provides for nonrec-
ognition of gain when property is invol-
untarily converted and replaced with
property that is similar or related in ser-
vice or use. Section 1033(e)(1) provides
that a sale or exchange of livestock (other
than poultry) held by a taxpayer for draft,
breeding, or dairy purposes in excess of
the number that would be sold following
the taxpayer’s usual business practices is
treated as an involuntary conversion if the
livestock is sold or exchanged solely on
account of drought, flood, or other weath-
er-related conditions.
.02 Replacement Period. Section
1033(a)(2)(A) generally provides that
gain from an involuntary conversion is
recognized only to the extent the amount
realized on the conversion exceeds the
cost of replacement property purchased
during the replacement period. If a sale
or exchange of livestock is treated as an
involuntary conversion under § 1033(e)
(1) and is solely on account of drought,
flood, or other weather-related conditions
that result in the area being designated as
eligible for assistance by the federal gov-
ernment, § 1033(e)(2)(A) provides that the
replacement period ends four years after
the close of the first taxable year in which
any part of the gain from the conversion is
realized. Section 1033(e)(2)(B) provides
that the Secretary may extend this replace-
ment period on a regional basis for such
additional time as the Secretary deter-
mines appropriate if the weather-related
conditions that resulted in the area being
designated as eligible for assistance by
the federal government continue for more
than three years. Section 1033(e)(2) is
effective for any taxable year with respect
to which the due date (without regard to
extensions) for a taxpayer’s return is after
December 31, 2002.
SECTION 3. EXTENSION OF
REPLACEMENT PERIOD UNDER
§ 1033(e)(2)(B)
Notice 2006-82, 2006-2 C.B. 529,
provides for extensions of the replace-
ment period under § 1033(e)(2)(B). If a
sale or exchange of livestock is treated as
an involuntary conversion on account of
drought and the taxpayer’s replacement
period is determined under § 1033(e)
(2)(A), the replacement period will be
extended under § 1033(e)(2)(B) and
Notice 2006-82 until the end of the tax-
payer’s first taxable year ending after the
first drought-free year for the applicable
region. For this purpose, the first drought-
free year for the applicable region is the
first 12-month period that (1) ends August
31; (2) ends in or after the last year of the
taxpayer’s four-year replacement period
determined under § 1033(e)(2)(A); and
(3) does not include any weekly period
for which exceptional, extreme, or severe
drought is reported for any location in the
applicable region. The applicable region
is the county that experienced the drought
conditions on account of which the live-
stock was sold or exchanged and all coun-
ties that are contiguous to that county.
A taxpayer may determine whether
exceptional, extreme, or severe drought is
reported for any location in the applicable
region by reference to U.S. Drought Mon-
itor maps that are produced on a weekly
basis by the National Drought Mitigation
Center. U.S. Drought Monitor maps are
archived at https://droughtmonitor.unl.
edu/Maps/MapArchive.aspx.
In addition, Notice 2006-82 provides
that the Internal Revenue Service will
publish in September of each year a list of
counties
1
for which exceptional, extreme,
or severe drought was reported during the
preceding 12 months. Taxpayers may use
this list instead of U.S. Drought Monitor
maps to determine whether exceptional,
extreme, or severe drought has been
reported for any location in the applicable
region.
The Appendix to this notice contains
the list of counties for which excep-
tional, extreme, or severe drought was
reported during the 12-month period
ending August 31, 2026. Under Notice
2006-82, the 12-month period ended on
August 31, 2026, is not a drought-free
year for an applicable region that includes
any county on this list. Accordingly, for
a taxpayer who qualified for a four-year
replacement period for livestock sold or
exchanged on account of drought and
whose replacement period is scheduled to
expire at the end of 2026 (or, in the case of
a fiscal year taxpayer, at the end of the tax-
able year that includes August 31, 2026),
the replacement period will be extended
under § 1033(e)(2) and Notice 2006-82 if
the applicable region includes any county
on this list. This extension will continue
until the end of the taxpayer’s first taxable
year ending after a drought-free year for
the applicable region.
SECTION 4. DRAFTING
INFORMATION

is Lewis Saideman from the Office of
Associate Chief Counsel (Income Tax
& Accounting). For further information

While Notice 2006-82 uses the term “counties,” this notice lists other applicable regions as well (e.g., boroughs, parishes, planning regions, etc.). Beginning in 2026, U.S. Drought Monitor
Mitigation Center’s U.S. Drought Monitor began tracking data for Connecticut by planning region.

Request for Additional
Comments on Issues under
§ 1400Z-2 Regarding
Investments in Qualified
Opportunity Funds and
Qualified Opportunity Zone
Businesses
Notice 2026-55
SECTION 1. PURPOSE
This notice requests comments on
issues arising under § 1400Z-2 of the
Internal Revenue Code (Code)
1
, as
amended by § 70421 of Public Law 119-
21, 139 Stat. 72 (July 4, 2025), commonly
known as the One, Big, Beautiful Bill Act
(OBBBA), regarding investments in busi-
nesses located in qualified opportunity
zones (QOZs), including on whether addi-
tional guidance is needed under § 1400Z-2
to address issues relating to qualifying
investments of amounts of eligible gains
made by taxpayers in qualified oppor-
tunity funds (QOFs) and investments of
such funds made by QOFs in qualified
opportunity zone businesses (QOZBs).
2
SECTION 2. BACKGROUND
.01 Statutory Framework. Section
13823 of Public Law 115-97, 131 Stat.
2054, 2183-88 (December 22, 2017), com-
monly known as the Tax Cuts and Jobs Act
(TCJA), added §§ 1400Z-1 and 1400Z-2
to the Code. Section 41115 of the Bipar-
tisan Budget Act of 2018 (BBA 2018),
Public Law 115-123, 132 Stat. 64, 161
(February 9, 2018), amended § 1400Z-1
to add a special rule for Puerto Rico. Sec-
tion 70421 of the OBBBA amended prior
§§ 1400Z-1 and 1400Z-2 in several ways,
including establishing ongoing tax incen-
tives for investing in qualified opportunity
funds (QOFs). All references hereinafter
in this notice to “prior § 1400Z-1” and
“prior § 1400Z-2” refer to §§ 1400Z-1 and
1400Z-2, as in effect after amendment of
the Code by both § 13823 of the TCJA,
and by § 41115 of the BBA 2018, but prior
to amendment by § 70421 of the OBBBA.
All references in this notice to “§ 1400Z-
1” and “§ 1400Z-2” refer to §§ 1400Z-1
and 1400Z-2 as amended by § 70421 of
the OBBBA.
Section 1400Z-2 allows the deferral
of inclusion in gross income for certain
realized gains to the extent that corre-
sponding amounts are timely invested in
a corporation or partnership that meets the
requirements to be certified as a QOF. If
certain qualifications and holding period
requirements are met, then (i) a portion of
such deferred gains may be excluded from
gross income, and (ii) gain on the taxpay-
er’s investment of such amounts in a QOF
may be excludable from gross income.
Additionally, § 1400Z-2(e)(4) expressly
delegates authority to the Secretary of the
Treasury or the Secretary’s delegate (Sec-
retary) to prescribe such regulations as
may be necessary or appropriate to carry
out the purposes of § 1400Z-2, including:
rules for the certification of QOFs; rules
to ensure a QOF has a reasonable period
of time to reinvest the return of capital
from investments in QOZ stock and QOZ
partnership interests, and to reinvest pro-
ceeds received from the sale or disposition
of qualified opportunity zone property
(QOZP); and rules to prevent abuse.
For amounts invested in QOFs after
December 31, 2026, the OBBBA amend-
ments to prior § 1400Z-2(b) generally
provide that deferred gain is included in
gross income no later than five years after
the date of the qualifying investment. If an
investment is held for at least five years,
its basis is increased by 10 percent of
the deferred gain, or by 30 percent in the
case of an investment in a qualified rural
opportunity fund (QROF).
For investments made after Decem-
ber 31, 2026, the OBBBA also amended
§ 1400Z-2(c) to provide that for an invest-
ment held for at least 10 years for which
the taxpayer makes the election under
§ 1400Z-2(c), the basis of the investment
is generally its fair market value on the
date of sale or exchange if the investment
is sold before the date that is 30 years after
the investment date. In any other case, the
basis is its fair market value on the date
that is 30 years after the investment date.
In addition, for QOZP acquired after
December 31, 2026, the OBBBA amend-
ments to § 1400Z-2(d) replaced the former
“December 31, 2017,” acquisition-date
references with requirements determined
by reference to an “applicable start date”
for qualified opportunity zone business
property (QOZBP) and an “applicable
date” for QOZ stock and QOZ partnership
interests.
.02 Regulations and Other Guidance
under §§ 1400Z-1 and 1400Z-2.
In early 2020, the Department of the
Treasury (Treasury Department) and
the Internal Revenue Service (IRS) pub-
lished final regulations (T.D. 9889) in the
Federal Register (85 F.R. 1866 (Jan. 13,
2020), corrected by 85 F.R. 19082 (Apr. 6,
2020)) under § 1400Z-2 (§ 1400Z-2 reg-
ulations). The § 1400Z-2 regulations are
comprised of §§ 1.1400Z2(a)-1 through
1.1400Z2(f)-1 and include rules concern-
ing eligible taxpayers and eligible gains,
the 180-day investment period, inclu-
sion events that end deferral of gains, the
election under § 1400Z-2(c), the 90-per-
cent investment standard for QOFs, and
requirements for qualification as a QOZB,
QOZB working capital safe harbors,
leased property, original use, and sub-
stantial improvement of property under
§ 1400Z-2.
In 2021, the Treasury Department and
the IRS published a notice of proposed
rulemaking in the Federal Register (86
F.R. 19585), which proposed rules for the
reduction or elimination of withholding
under §§ 1445, 1446(a), or 1446(f) of the
Code on transfers that give rise to gain
that is deferred under § 1400Z-2(a) and
for modifications to the working capital
safe harbor.
After the enactment of the OBBBA,
the Treasury Department and the IRS pub-
lished Notice 2025-50, 2025-43 I.R.B.
542 (2025), to provide guidance concern-
ing the definition of a “rural area” under
§ 1400Z-2(b)(2)(C)(ii) and the application
of the reduced substantial-improvement
threshold for property in a QOZ com-
prised entirely of a rural area. In addition,

October 13, 2026 498 Bulletin No. 2026–42
the Treasury Department and the IRS pub-
lished Rev. Proc. 2026-14, 2026-20 I.R.B.
910 (2026), to provide procedures under
§ 1400Z-1 for State chief executive offi-
cers to nominate population census tracts
for QOZ designation effective January 1,
2027.
In July 2026, the Treasury Department
and the IRS published Notice 2026-40,
2026-28 I.R.B. 33 (2026), to provide tran-
sitional guidance concerning the designa-
tion rules under § 1400Z-1, investors with
gains and qualifying investments that span
the December 31, 2026, transition date,
the acquisition of QOZP after December
31, 2026, in previously designated QOZs,
and the continued operation of QOFs and
QOZBs after a previously designated
QOZ’s designation period expires. On
September 11, 2026, the Treasury Depart-
ment and the IRS published proposed
regulations concerning the new informa-
tion-reporting requirements and updated
QOF certification and decertification pro-
cedures under §§ 1400Z-2, 6039K, and
6039L (91 F.R. 57968).
SECTION 3. REQUEST FOR
COMMENTS
.01 Comments Regarding Need for
Additional Guidance. The Treasury
Department and the IRS request additional
comments on all aspects of the implemen-
tation of § 1400Z-2 following the amend-
ments made by the OBBBA. Commenters
are encouraged to identify provisions of
the § 1400Z-2 regulations or other guid-
ance that should be retained, modified, or
supplemented, and to describe in techni-
cal detail the legal analysis supporting any
such changes based on the statutory text
of § 1400Z-2 and other applicable provi-
sions of the Code. Additional comments
describing common transaction struc-
tures or factual examples in which exist-
ing guidance produces uncertain results
would be particularly helpful. In addition
to comments of a general nature, the Trea-
sury Department and the IRS request com-
ments in response to specific questions as
discussed below.
(1) Executive Order 14394. Section
5(a) and (b) of Executive Order 14394 of
March 13, 2026, Removing Regulatory
Barriers to Affordable Home Construc-
tion (91 F.R. 13207), directs the Secretary
and the Secretary of Housing and Urban
Development to jointly evaluate Admin-
istration actions to better align programs
and incentives with Opportunity Zone tax
incentives to expand investment in sin-
gle-family home construction, including
considering lawful mechanisms to link
grants, financing tools, or other incen-
tives with new or increased investment
in QOFs engaged in the development and
sale of single-family homes.
(a) Comments are requested on actions,
consistent with existing statutory author-
ity, through which the tax incentives pro-
vided by § 1400Z-2 could better support
Department of Housing and Urban Devel-
opment (HUD) programs and incentives
to expand investment in single-family
home construction, including considering
lawful mechanisms to link grants, financ-
ing tools, or other incentives with new or
increased investment in QOFs engaged in
the development and sale of single-fam-
ily homes. Specifically, comments are
requested on any opportunities that exist
to coordinate § 1400Z-2 with the New
Markets Tax Credit under § 45D to pro-
mote single-family home construction in
census tracts that qualify both as QOZs
and as low-income communities for the
purposes of the New Markets Tax Credit.
(b) Taking into account the preamble
discussions of legal authority published
in the Federal Register at 84 F.R. 18652,
18660 (May 1, 2019), and at 85 F.R. 1866,
1931-1932 (January 13, 2020), including
the conclusion in the preamble to the 2020
final regulations that § 1400Z-2 permits
gain deferral only at the QOF-owner level
and that asset-level nonrecognition must
arise under another provision of subtitle
A of the Code (subtitle A), what statutory
or legal authority, including § 1400Z-2(e)
(4)(B), the broader grants of authority in
§ 1400Z-2(e)(4) and § 7805(a), or any
grant of authority under another pro-
vision of the Code, is there that would
support regulations under which some
or all income or gain realized by a QOF
engaged in developing and selling sin-
gle-family homes would be deferred from
inclusion in gross income if the QOF rein-
vests the proceeds from selling its housing
inventory into its trade or business within
a reasonable period of time? Commenters
recommending any particular interpreta-
tion of the law are requested to set forth
their legal analysis clearly and in detail,
including how any such rules would inter-
act with otherwise applicable recognition
rules under subtitle A and the anti-abuse
rule of § 1400Z-2(e)(4)(C). Comments
are specifically requested on whether the
legal analysis would differ between (i)
income or gain from a QOF’s direct sale
or disposition of housing inventory and
(ii) gain from a QOF’s sale or disposition
of QOZ stock or a QOZ partnership inter-
est in a QOZB engaged in developing and
selling single-family homes. Commenters
are also requested to provide additional
legal analysis regarding the authority
under which inclusion in gross income of
income or gain from the sale or disposi-
tion of housing inventory allocated to a
QOF from a QOZB classified as a part-
nership for Federal income tax purposes
could be deferred.
(c) If there were adequate statutory
authority to defer inclusion in gross
income of any income or gain realized on
the sale or disposition of housing inven-
tory, when should the deferred income
or gain be included in gross income, and
what reinvestment, holding-period, basis,
character (that is, ordinary or capital), or
other limitations or clarifications would be
necessary to tailor any “interim-gain” rule
to the limits of that statutory authority?
For example, would changes to the defi-
nition of QOZBP be required, such as the
rules for substantial improvement under
§ 1400Z-2(d)(2)(D)(ii)?
(d) Should any such deferral be limited
to businesses engaged in developing and
selling single-family homes, rather than
making it available to other inventory sell-
ing businesses? What administrable eligi-
bility criteria and anti-abuse safeguards
would be necessary to define and enforce
that limitation?
(2) Working capital safe harbor. An
eligible entity must meet certain require-
ments to be a QOZB, including the
requirement of § 1397C(b)(8) of the Code
that less than 5 percent of the average
of the aggregate unadjusted bases of the
entity’s property be attributable to non-
qualified financial property, as defined in
§ 1397C(e). See § 1400Z-2(d)(3)(A)(ii).
Section 1397C(e) excludes from non-
qualified financial property reasonable
amounts of working capital that are held
in cash, cash equivalents, or debt instru-

Bulletin No. 2026–42 499 October 13, 2026
ments with a term of 18 months or less. See
§ 1.1400Z2(d)-1(d)(3)(iv). The § 1400Z-2
regulations provide QOZBs with a safe
harbor for treating an amount of work-
ing capital as reasonable for purposes of
§ 1397C(e) if certain requirements are sat-
isfied (working capital safe harbor). See
§ 1.1400Z2(d)-1(d)(3)(v) (providing the
scope of the working capital safe harbor
and conditions for eligibility).
(a) Should a QOZB be permitted to
modify a working capital safe harbor
plan? If so, under what circumstances
should the modifications be permitted?
Should a modified plan be required to
remain “substantially consistent” with the
original plan? How should “substantially
consistent” be defined? How should these
rules apply when a QOZB has more than
one overlapping or sequential application
of the working capital safe harbor under
§ 1.1400Z2(d)-1(d)(3)(v)(E)?
(b) The Treasury Department and the
IRS have received questions regarding
the expenditure of working capital assets
on property that may not be QOZBP. Sec-
tion 1.1400Z2(d)-1(d)(2) provides that a
QOZB must satisfy the 70-percent tangi-
ble property standard, which requires that
at least 70 percent of the tangible property
owned or leased by a QOZB is QOZBP.
What additional rules or guidance would
be useful in clarifying how expenditures
of working capital assets affect the 70-per-
cent tangible property standard?
(3) Rules for operating businesses.
What additional guidance would help
operating businesses to benefit from the
tax incentives in § 1400Z-2? For example,
is additional guidance needed regarding
the use of QOZBP, including inventory, in
QOZs?
(4) Election for investments held for at
least 10 years and the 30-year rule. For
qualifying investments made after Decem-
ber 31, 2026, § 1400Z-2(c) provides a fair
market value basis rule for a qualifying
investment held for at least 10 years, sub-
ject to a 30-year limit. What additional
guidance is needed concerning the time
and manner of making the § 1400Z-2(c)
election in the case of an investment that
has not been sold or exchanged by the date
that is 30 years after the investment was
made? What valuation rules or substanti-
ation requirements would be appropriate
for determining fair market value on that
date? How should subsequent apprecia-
tion or depreciation be treated after basis
is determined by reference to fair market
value on the 30-year date? What modifi-
cations to § 1.1400Z2(c)-1 are needed for
QOFs classified as partnerships or S cor-
porations, including rules governing dis-
positions of QOF assets and interests held
through pass-through entities?
(5) Additional guidance for QOFs,
QOZBs, and inclusion events.
(a) Are additional rules needed regard-
ing corporations and partnerships that
are either QOFs, QOZBs, or investors in
QOFs?
(b) Should gain arising from an inclu-
sion event be eligible for deferral under
§ 1.1400Z2(a)-1(b)(11)(iv) only if the
inclusion event is treated as a sale or
exchange?
(c) Should the rules regarding the inclu-
sion of the deferred gain under § 1400Z-
2(b) be clarified in regulations to address
situations where there are debt-financed
distributions or debt-financed losses that
impact the calculation of the deferred
gain?
(d) Should the rules regarding dis-
guised sales under § 1.1400Z2(a)-1(c)(2)
be modified?
(6) Opportunity Zone investment in
Tribal and Alaska Native communities.
Certain population census tracts des-
ignated as QOZs overlap with areas in
Tribal and Alaska Native communities,
including trust lands, Alaska Native Vil-
lages, and Tribal areas in Oklahoma.
The OBBBA amendments to § 1400Z-2
provide enhanced benefits for qualify-
ing investments in rural areas. The Trea-
sury Department and the IRS request
comments on how the Opportunity Zone
incentive has been used in Tribal and
Alaska Native communities, as well as
any suggested clarifications that may
encourage investment in QOZs on Tribal
and ANCSA lands.

Update for Weighted
Average Interest Rates,
Yield Curves, and Segment
Rates
Notice 2026-57
This notice provides guidance on the
corporate bond monthly yield curve, the
corresponding spot segment rates used
under § 417(e)(3), and the 24-month aver-
age segment rates under § 430(h)(2) of the
Internal Revenue Code. In addition, this
notice provides guidance as to the inter-
est rate on 30-year Treasury securities
under § 417(e)(3)(A)(ii)(II) as in effect for
plan years beginning before 2008 and the
30-year Treasury weighted average rate
under § 431(c)(6)(E)(ii)(I).
YIELD CURVE AND SEGMENT
RATES
Section 430 specifies the minimum
funding requirements that apply to sin-

October 13, 2026 500 Bulletin No. 2026–42
gle-employer plans (except for CSEC plans
under § 414(y)) pursuant to § 412. Section
430(h)(2) specifies the interest rates that
must be used to determine a plan’s target
normal cost and funding target. Under
this provision, present value is generally
determined using three 24-month average
interest rates (“segment rates”), each of
which applies to cash flows during speci-
fied periods. To the extent provided under
§ 430(h)(2)(C)(iv), these segment rates
are adjusted by the applicable percentage
of the 25-year average segment rates for
the period ending September 30 of the
year preceding the calendar year in which
the plan year begins.
1
However, an elec-
tion may be made under § 430(h)(2)(D)
(ii) to use the monthly yield curve in place
of the segment rates.
Section 1.430(h)(2)-1(d) provides
rules for determining the monthly cor-
porate bond yield curve, and § 1.430(h)
(2)-1(c) provides rules for determining
the 24-month average corporate bond
segment rates used to compute the tar-
get normal cost and the funding target.
Consistent with the methodology spec-
ified in § 1.430(h)(2)-1(d), the monthly
corporate bond yield curve derived from
August 2026 data is in Table 2026-8 at the
end of this notice. The spot first, second,
and third segment rates for the month of
August 2026 are, respectively, 4.65, 5.75,
and 6.73.
The 24-month average segment rates
determined under § 430(h)(2)(C)(i)
through (iii) must be adjusted pursuant
to § 430(h)(2)(C)(iv) to be within the
applicable minimum and maximum per-
centages of the corresponding 25-year
average segment rates. Those percent-
ages are 95% and 105% for plan years
beginning in 2025, 2026 and 2027. For
this purpose, any 25-year average seg-
ment rate that is less than 5% is deemed
to be 5%. The 25-year average segment
rates for plan years beginning in 2025
and 2026 were published in Notice
2024-67, 2024-41 I.R.B. 726 and Notice
2025-47, 2025-40 I.R.B. 441, respec-
tively. For plan years beginning in 2027,
based on the segment rates applicable
for October 2001 to September 2026, the
25-year averages for the period ending
September 30, 2026, of the first, second,
and third segment rates are 3.13, 4.91,
and 5.61 percent, respectively.
24-MONTH AVERAGE CORPORATE
BOND SEGMENT RATES
The three 24-month average corporate
bond segment rates applicable for Sep-
tember 2026 without adjustment for the
25-year average segment rate limits are as
follows:

The adjusted 24-month average seg-
ment rates set forth in the chart below
reflect § 430(h)(2)(C)(iv) of the Code. The
24-month averages applicable for Septem-
ber 2026, adjusted to be within the appli-
cable minimum and maximum percent-
ages of the corresponding 25-year average
segment rates in accordance with § 430(h)
(2)(C)(iv), are as follows:

30-YEAR TREASURY SECURITIES
INTEREST RATES
Section 431 specifies the minimum
funding requirements that apply to mul-
tiemployer plans pursuant to § 412. Sec-
tion 431(c)(6)(B) specifies a minimum
amount for the full-funding limitation
described in § 431(c)(6)(A), based on the
plan’s current liability. Section 431(c)(6)
(E)(ii)(I) provides that the interest rate
used to calculate current liability for this
purpose must be no more than 5 percent
above and no more than 10 percent below
the weighted average of the rates of inter-
est on 30-year Treasury securities during
the four-year period ending on the last
day before the beginning of the plan year.
Notice 88-73, 1988-2 C.B. 383, provides
guidelines for determining the weighted
average interest rate. The rate of interest
on 30-year Treasury securities for August
2026 is 5.23 percent. The Service deter-
mined this rate as the average of the daily
determinations of yield on the 30-year
Treasury bond maturing in May 2056
determined each day through August
12, 2026 and the yield on the 30-year
Treasury bond maturing in August 2056
determined each day for the balance of

Pursuant to § 433(h)(3)(A), the third segment rate determined under § 430(h)(2)(C) is used to determine the current liability of a CSEC plan (which is used to calculate the minimum amount
of the full funding limitation under § 433(c)(7)(C)).

September 2026, the weighted average
of the rates of interest on 30-year Trea-
sury securities and the permissible range
of rates used to calculate current liability
are as follows:

In general, the applicable interest rates
under § 417(e)(3)(D) are segment rates
computed without regard to a 24-month
average. Section 1.417(e)-1(d)(3) provides
guidelines for determining the minimum
present value segment rates. Pursuant to
that section, the minimum present value
segment rates determined for August 2026
are as follows:

Bulletin No. 2026–42 503 October 13, 2026
Eliminating Unnecessary
IRS Internal Revenue
Bulletin Guidance
Notice 2026-58
SECTION 1. PURPOSE
This notice continues the process of
eliminating extraneous and unnecessary
items of guidance published in the Internal
Revenue Bulletin (I.R.B.) by identifying
and obsoleting 71 revenue rulings, reve-
nue procedures, notices, and announce-
ments previously published in the I.R.B.
(I.R.B. guidance documents).
SECTION 2. BACKGROUND
On January 31, 2025, the President
issued Executive Order 14192, Unleash-
ing Prosperity Through Deregulation
(E.O. 14192). The purpose of E.O. 14192
includes reducing the economic burden
caused by regulation. To further this goal,
E.O. 14192 directs agencies to, among
other requirements, identify ten existing
regulations to be repealed for each reg-
ulation publicly proposed for notice and
comment or otherwise promulgated.
On February 19, 2025, the President
issued Executive Order 14219, Ensuring
Lawful Governance and Implementing
the President’s ‘Department of Govern-
ment Efficiency’ Deregulatory Initiative
(E.O. 14219). The purpose of E.O. 14219
includes eliminating “overbearing and
burdensome” regulations and other guid-
ance documents, and “[e]nding Federal
overreach.” To further these goals, E.O.
14219 directs agency heads to coordi-
nate with the Department of Government
Efficiency (DOGE) Team Leads and the
Office of Management and Budget to
identify regulations and other guidance
documents to be eliminated.
Accordingly, the Department of the
Treasury (Treasury Department) and the
Internal Revenue Service (IRS) have
undertaken a review of regulations and
I.R.B. guidance issued under the Internal
Revenue Code
1
to identify guidance to be
eliminated. This review is ongoing. Notice
2025-22, 2025-19 I.R.B. 1427, obsoleted
nine I.R.B. guidance documents. Notice
2025-36, 2025-30 I.R.B. 192, obsoleted
83 I.R.B. guidance documents.
This notice obsoletes 71 I.R.B. guid-
ance documents. These 71 guidance doc-
uments no longer provide useful informa-
tion, and clarifying their status as obsolete
will streamline administration of the tax
laws; reduce the volume of guidance that
taxpayers and their advisors need to
review for compliance with the tax laws;
and increase clarity of the tax law. The
Treasury Department and the IRS antic-
ipate revoking or obsoleting additional
similar guidance documents in the near
future.
SECTION 3. OBSOLETED
GUIDANCE
.01 Section 9674(a) of the American
Rescue Plan Act of 2021, Public Law 117-
2, 153 Stat. 4 (2021) (ARP) was repealed
by section 70432 of Public Law 119-21,
139 Stat. 72 (2025), commonly known
as the One, Big, Beautiful Bill Act. The
following guidance is obsolete because
it provides transition periods for IRS
enforcement and administration of the
minimum reporting threshold in section
6050W(e) for Form 1099-K, Payment
Card and Third Party Network Transac-
tions, based on the now-repealed section
9674(a) of the ARP:

Section 6050W(e), 2024-51 I.R.B. 1349.

ing the now-repealed section 9674(a) of
the ARP.

This notice provides that calendar year
2022 is a transition period for implement-
ing the now-repealed section 9674(a) of
the ARP.
.02 The following guidance is obsolete
because it concerns Code sections that
were repealed by section 13404(a) of Pub-
lic Law 115-97, 131 Stat. 2054 (2017),
commonly known as the Tax Cuts and
Jobs Act (TCJA):
(1) Notice 2010-17, Qualified School
Construction Bond Allocations for 2010,
2010-14 I.R.B. 519. This notice provides
the face amount of qualified school con-
struction bonds allocated by the Treasury
Department to each state and large local
education agency for 2010 under now-re-
pealed section 54F(d).
(2) Notice 2008-70, Qualified For-
estry Conservation Bonds, 2008-36 I.R.B.

servation bonds under now-repealed sec-
tion 54B(c).

for allocation of the available volume cap
for clean renewable energy bonds under

(4) Announcement 2010-54, Applica-
tions from Cooperative Electrical Com-
panies for Authority to Issue New Clean
Renewable Energy Bonds Now Being

This announcement solicits applications
from cooperative electrical companies
for previously unallocated volume cap
authority to issue new clean renewable
energy bonds under now-repealed section
54C.
.03 The following guidance was obso-
leted by the enactment of section 2053(c)
(1)(D) (disallowing an estate tax deduc-
tion for interest attributable to extensions
of time for payment of tax under section
6166) in section 503(b)(1) of the Taxpayer
Relief Act of 1997, Public Law 105-34,
111 Stat. 788 (1997):
(1) Rev. Rul. 78-125, Interest on
Installment Payment of Tax, 1978-1 C.B.
292. This revenue ruling holds that interest
payable on estate tax installments under
section 6166 is deductible as an adminis-
tration expense under section 2053(a)(2).
1
Unless otherwise specified, all “section” or “§” references are to sections of the Internal Revenue Code (Code) or the Internal Revenue Regulations (CFR Title 26).

October 13, 2026 504 Bulletin No. 2026–42
(2) Rev. Proc. 81-27, 1981-27 I.R.B.
20. This revenue procedure sets forth the
procedure to be followed by an estate
when installment payments due under
sections 6166 or 6166A are recomputed
because of a reduction in the estate tax
caused by the payment of interest on the
tax due.
.04 The following guidance is obsolete
because it relates to Code sections that
have been amended or repealed:
(1) Rev. Rul. 90-85, Passive Losses
and Tax Shelter Registration, 1990-42
I.R.B. 5. This revenue ruling holds that
representations concerning certain losses
of a passive activity under section 469(c)
have no effect on the computation of an
investor’s tax shelter ratio for purposes of
section 6111. Section 6111 was amended
by section 815(a) of the American Jobs
Creation Act of 2004, Public Law 108-
357, 118 Stat. 1418 (2004).
(2) Rev. Rul. 82-174, Windfall Profit
Tax; Deduction; Accrual Method of
Accounting, 1982-42 I.R.B. 6. This rev-
enue ruling addresses when an accrual
method producer of crude oil may deduct
the windfall profit tax under section 4995.
The revenue ruling also addresses when
cash method producers of crude oil are
required to reduce their deduction for
refunds or credits of the windfall profit
tax. Section 4995 was repealed by section
1941(a) of the Omnibus Trade and Com-
petitiveness Act of 1988, Public Law 100-
418, 102 Stat. 1107(1988) (1988 Omnibus
Act).
(3) Rev. Rul. 81-99, Windfall Profit
Tax; When Deductible, 1981-13 I.R.B. 32.
This revenue ruling addresses when a cash
method producer of crude oil may deduct
the windfall profits tax imposed under
section 4995. Section 4995 was repealed
by section 1941(a) of the 1988 Omnibus
Act.
(4) Rev. Rul. 75-112, Ratable Inclu-
sion of Interest; Church Bonds, 1975-1
C.B. 274. This revenue ruling generally
concludes that the original issue discount
ratable inclusion rules in section 1232(a)
(3) apply to bonds that are issued by a
church and provide for a redemption price
in excess of the issue price. Section 1232
was repealed by section 42(a)(1) of the
Deficit Reduction Act of 1984, Public Law
98-369, 98 Stat. 494 (1984) (DEFRA).
However, see section 1272 for the original
issue discount inclusion rules that apply to
bonds and other debt instruments.
(5) Rev. Rul. 56-60, 1956-1 C.B. 443.
This revenue ruling holds that the alter-
nate valuation date election cannot be
taken in circumstances where the gross
estate on the date of death is below the
statutory exemption. This rule is now
addressed in section 2032(c), which was
amended by section 1023(a) of DEFRA,
and § 20.2032-1(b)(1), which provide that
the election must decrease the gross estate
and the estate tax.
(6) Rev. Rul. 55-333, 1955-1 C.B.
449. This revenue ruling holds that sec-
tion 811(j) of the Internal Revenue
Code of 1939 does not limit application
thereof to the estates of decedents that
have decreased in value during the one-
year period following the date of death.
This guidance was obsoleted when sec-
tion 1023(a) of DEFRA amended section
2032(c).
(7) Rev. Rul. 54-106, 1954-1 C.B. 28.
This revenue ruling generally concludes
that bonds issued by a municipality for
the purpose of financing the acquisition
or construction of municipally owned
industrial plants for lease to private enter-
prises constitute obligations of a political
subdivision within the meaning of section
22(b)(4) of the Internal Revenue Code of
1939. The analysis in this revenue ruling
was obsoleted by the enactment of statutes
governing the tax-exemption of industrial
development bonds in section 107 of the
Revenue and Expenditure Control Act of
1968, Public Law 90-364, 82 Stat. 251
(1968).
(8) Notice 2010-51, Information
Reporting Under the Amendments to
Section 6041 for Payments to Corpora-
tions and Payments of Gross Proceeds
and With Respect to Property, 2010-29
I.R.B. 83. This notice solicits public
comments regarding guidance to be pro-
vided to payors and other persons affected
by the amendments to section 6041 by
section 9006 of the Patient Protection
and Affordable Care Act of 2010, Pub-
lic Law 111-148, 124 Stat. 119 (2010),
which expanded the information reporting
requirements under that section to apply
to payments made by corporations and to
include payments of gross proceeds with
respect to property. This amendment was
repealed by section 2(a) of the Compre-
hensive 1099 Taxpayer Protection and
Repayment of Exchange Subsidy Over-
payments Act of 2011, Public Law 112-9,
125 Stat. 36 (2011).
(9) Notice 98-57, D.C. Enterprise
Zone/Census Tracts, 1998-47 I.R.B. 9.
This notice provides the identification
of those census tracts in the District of
Columbia constituting the District of
Columbia Enterprise Zone for purposes
of section 1400 and the DC Zone for pur-
poses of section 1400B. Sections 1400
and 1400B were repealed by division T,
title IV, section 401(d)(4)(A) of the Con-
solidated Appropriations Act, 2018, Pub-
lic Law 115-141, 132 Stat. 348 (2018).
(10) Notice 96-8, Cash Balance Pen-
sion Plans, 1996-6 I.R.B. 23. This notice
provides guidance concerning the require-
ments of sections 411(a) and 417(e) with
respect to the determination of the amount
of a single sum distribution from a cash
balance plan. This guidance was obsoleted
by section 701(b) of the Pension Protec-
tion Act of 2006, Public Law 109-280,
120 Stat. 780 (2006), which enacted sec-
tion 411(a)(13) and (b)(5) of the Code.
(11) Notice 93-7, Changes in Withhold-
ing on Gambling Winnings, 1993-3 I.R.B.

the withholding rate and gambling pro-
ceeds threshold under section 3402(q)
made by the 1992 Energy Policy Act of
1992, Public Law 102-486, 106 Stat. 2776
(1992). The withholding rate change it
announced was subsequently changed
by section 101(c)(8) of the Economic
Growth and Tax Relief Reconciliation Act
of 2001, Public Law 107-16, 115 Stat. 38
(2001), making this notice obsolete.
.06 Rev. Proc. 98-47, Business Expense;
Environmental Remediation Costs; Elec-
tion, 1998-37 I.R.B. 8. This revenue pro-
cedure provides procedures to make the
election to deduct qualified environmental
remediation expenditures under section
198. Pursuant to section 198(h), section
198 is not applicable to expenditures paid
or incurred after December 31, 2011, so
the guidance is obsolete.
.07 The following guidance is obso-
lete because the subject matter is now
addressed by final regulations:
(1) Rev. Rul. 2000-4, Business
Expenses, Capital Expenditures; ISO
9000 Costs, 2000-4 I.R.B. 331. This rev-

(3) Rev. Rul. 94-12, Incidental Repairs
as Business Expenses, 1994-8 I.R.B. 5.
This revenue ruling holds that Indopco,
Inc. v. Commissioner, 503 U.S. 79 (1992),

tal repair costs as business expenses,
which are generally deductible under sec-
tion 162. This issue is now addressed in

excluding accrued but unpaid expenses
and accounts payable. This definition is
now in § 1.752-1(a).

ditures; Rehabilitation of Railroad Cars,
1988-28 I.R.B. 4. This revenue ruling
addresses whether cyclical expendi-
tures for major rehabilitations of railroad
freight-train cars are deductible as ordi-
nary and necessary business expenses
under section 162 or must be capitalized
under section 263(a). This issue is now

essary business expenses under section

263(a). This issue is now addressed in
§§ 1.263(a)-5(a)(8) (requiring the capi-
talization of amounts paid to facilitate a
stock issuance) and 1.263(a)-5(l) Example

ple 3 (dedicated improvements).
(11) Rev. Rul. 56-290, 1956-1 C.B.
445. This revenue ruling holds that, if a
decedent’s income is reported on a joint
return filed by the decedent and the dece-
dent’s spouse, only a portion of the joint
tax liability reported on that return is
deductible as a debt of the decedent under
section 2053 for estate tax purposes. The
deductible portion is determined by calcu-
lating each spouse’s separate tax liability,
as if they had filed separately, and multi-
plying the joint tax liability by the ratio
of the decedent’s separate tax liability to
the total of the separate tax liabilities. This
rule is now addressed by § 20.2053-6(f).
(12) Rev. Rul. 57-78, 1957-1 C.B. 300.
This revenue ruling holds that, in comput-
ing the separate tax liabilities of spouses
(as described in Rev. Rul. 56-290), the
decedent’s separate income tax liability
is computed on the decedent’s income for
the portion of the year prior to the date of
death, and the spouse’s separate tax liabil-
ity is computed on the spouse’s income for
the entire year. This rule is now addressed
by § 20.2053-6(f).

due with respect to gifts made by the dece-
dent and paid by his executors is deduct-
ible under section 812(b) of the Internal
Revenue Code of 1939 as a tax accrued
prior to the decedent’s death, constituting
an enforceable obligation of the decedent
existing at the time of death. This rule is
now addressed by §§ 20.2012-1(a) and
20.2053-6(d).
(14) Rev. Rul. 54-135, 1954-1 C.B.
205. This revenue ruling holds that where
a donor endorses a certificate of stock
and delivers it to his bank or broker with

the gift is completed for gift tax purposes
on the date the stock is transferred to the
donee on the books of the corporation. This
rule is now provided in § 25.2511-2(h).

provides that the IRS will automatically
approve a revocation request if certain

and consistent treatment of participating
employers during the plan year. The revo-
cation period has closed.
(4) Rev. Proc. 2008-47, 2008-31 I.R.B.
272. This revenue procedure describes the
conditions under which modifications to
certain subprime mortgage loans will not
cause the IRS to challenge the tax status
of certain securitization vehicles that hold
the loans or to assert that those modifica-
tions create a liability for tax on a prohib-
ited transaction. This revenue procedure
applies only to transactions occurring on

.09 The following guidance is obsolete
because it requested comments from the
public and the public comments are no
longer needed:
(1) Notice 2009-79, Modifications of
Commercial Mortgage Loans Held by
an Investment Trust, 2009-40 I.R.B. 454.
This notice requests comments by Novem-
ber 14, 2009, on whether guidance related

(3) is appropriate and the extent to which
the requested changes are consistent with
the rules regarding fixed investment trusts
under § 301.7701-4(c). The Treasury
Department and the IRS received sev-
eral public comments in response to this
notice but have published no guidance on

this notice but have published no guidance
on the subject.
(4) Notice 2006-34, Taxation of Cross
Licensing Arrangements, 2006-14 I.R.B.
705. This notice requests comments by
May 31, 2006, regarding certain transac-

(71 F.R. 48590 (withdrawn) and 73 F.R.
12838), temporary regulations (TD 9564,
76 F.R. 81060), and two sets of final regu-
lations (TD 9636, 78 F.R. 57686, and TD

F.R. 77701), and final regulations (TD
9107, 69 F.R. 436) have been issued.

Gaming Corp. v. Comm’r, 177 F.3d 1096
(9th Cir. 1999)), and the comments were
considered mooted by the decision in
Boyd Gaming.
.10 The following guidance is obsolete
by its own terms:
(1) Rev. Proc. 2014-18, Simplified
Method for Certain Taxpayers to Obtain
an Extension of Time, 2014-7 I.R.B. 513.
This revenue procedure provides a simpli-
fied method for certain taxpayers to obtain
an extension of time to make a portabil-
ity election under section 2020(c)(5)(A),
by which a decedent’s unused exclusion
amount becomes available to the surviv-
ing spouse’s subsequent transfers during
life or death. The guidance expired on
December 31, 2014.
(2) Rev. Proc. 86-48, 1986-52 I.R.B.
20. This revenue procedure permits tax-
payers that made an election under section
179 to expense all or a portion of the cost
of a passenger automobile that was placed
in service after June 18, 1984, and before
January 1, 1986, to amend their return
and modify their election to reduce the
expense election to the maximum amount
allowable under section 280F(a)(2) for
the taxable year in which the property is
placed in service.
(3) Notice 2001-79, Rent Holidays for
Qualified Airplane Leases, 2001-50 I.R.B.
576. The notice provides that certain rent
holidays will be disregarded in apply-
ing the uneven rent test in § 1.467-3(c)
(4) with respect to certain aircraft leases
entered into or modified between Septem-
ber 11, 2001, and June 28, 2002, for pur-
poses of determining whether the leases
are disqualified leasebacks or long-term
agreements under section 467(b)(4) sub-
ject to constant rental accrual under sec-
tion 467(b)(2).
(4) Announcement 90-39, Due Date
for Reporting and Paying Estate Tax
Extended for Qualified Domestic Trusts,
1990-12 I.R.B. 26. This document
announces an extension of the due date
for reporting and paying estate tax for a
qualified domestic trust. The time for fil-
ing under the extension has expired, and
§ 20.2056A-11 provides current guid-
ance as to due dates.
.11 The following guidance is obsolete
because it was affected by the release of
subsequent guidance documents:
(1) Rev. Proc. 2004-68, 2004-50 I.R.B.
969. This revenue procedure provides that
certain transactions with brief asset hold-
ing periods are not reportable transactions
for purposes of disclosure rules under
§ 1.6011-4(b)(7) but may be reportable
transactions for purposes of the disclo-
sure rules under § 1.6011-4(b)(2), (b)(3),
(b)(4), (b)(5), or (b)(6). Final regulations
published in the Federal Register (TD
9350, 72 F.R. 43146) on August 3, 2007,
removed this category of reportable trans-
action.

October 13, 2026 508 Bulletin No. 2026–42
(2) Rev. Proc. 2004-67, 2004-50
I.R.B. 967. This guidance provides that
certain book-tax differences are not taken
into account in determining whether a
transaction is a transaction with a signif-
icant book-tax difference, which was a
reportable transaction for purposes of the
disclosures rules under § 1.6011-4(b)(6).
This category of reportable transaction
was removed for disclosures after Janu-
ary 6, 2006, by Notice 2006-6, Notifica-
tion of Removal of the Transaction with
a Significant Book-Tax Difference Cat-
egory of Reportable Transaction Under
§ 1.6011-4, 2006-5 I.R.B. 385, and final
regulations published in the Federal Reg-
ister (TD 9350, 72 F.R. 43146) on August
3, 2007.
(3) Notice 2017-8, Transaction of
Interest – Section 831(b) Micro-cap-
tive Transactions, 2017-3 I.R.B. 423.
This notice modified Notice 2016-66,
Transaction of Interest – Section 831(b)
Micro-captive Transactions, 2016-47
I.R.B. 745, and extended the time for par-
ticipants and material advisors to file dis-
closure statements with regard to transac-
tions described in Notice 2016-66. Notice
2016-66 was obsoleted in a notice of pro-
posed rulemaking published in the Fed-
eral Register (REG-109309-22, 88 F.R.
21547) on April 11, 2023.
(4) Announcement 2006-50, Announce-
ment that Identifies Specified Covered Ser-
vices Eligible for Services Cost Method
Under Section 482 Regulations, 2006-34
I.R.B. 321. This announcement provides,
and requests comments on, a proposed
revenue procedure that would identify
particular services that are eligible to be
evaluated at cost under § 1.482-9T. The
revenue procedure in this announcement
was published as Rev. Proc. 2007-13,
2007-3 I.R.B. 295.
(5) Announcement 99-1, Modification
of Rev. Proc. 65-17, 1999-2 I.R.B. 41.
This announcement requests comments
on a proposed update to Rev. Proc. 65-17,
1965-1 C.B. 833, which provided pro-
cedures by which taxpayers could con-
form their accounts to reflect section 482
adjustments. Rev. Proc. 65-17 was subse-
quently superseded by Rev. Proc. 99-32,
1999-34 I.R.B. 296.
.12 Rev. Proc. 59-31, 1959-2 C.B. 949.
This revenue procedure sets forth the pro-
cedure to be followed with respect to (1)
establishing the tax-exempt status of char-
itable organizations created or organized
under the laws of Canada or Honduras
and (2) the deductibility of contribu-
tions thereto pursuant the tax convention
between the United States and Canada,
1943 C.B. 526, the United States-Can-
ada Supplementary Income Tax Conven-
tion, 1957-2 C.B. 1014, and the United
States-Honduras Income Tax Convention,
1957-2 C.B. 1033. The treaties underlying
this guidance are no longer in force.
.13 The following guidance is obsolete
because it relates to the Home Affordable
Modification Program (HAMP), which
expired in 2016:
(1) Notice 2009-36, Payments Made to
a REMIC Pursuant to the Home Afford-
able Modification Program, 2009-17
I.R.B. 883. This notice provides that the
Treasury Department and the IRS intend
to issue regulations regarding the applica-
tion of section 860G(d) to certain amounts
that may be paid to real estate mortgage
investment conduits (REMICs) as part of
the HAMP.
(2) Rev. Proc. 2009-23, 2009-17 I.R.B.
884. This revenue procedure describes the
conditions under which modifications to
residential mortgage loans pursuant to the
HAMP will not cause the IRS to challenge
the tax status of REMICs or fixed invest-
ment trusts or to assert that those modi-
fications to mortgages held by a REMIC
give rise to a prohibited transaction.
.14 Notice 2001-7, Reporting of Gross
Proceeds Payments to Attorneys, 2001-4
I.R.B. 374. This notice announced that
the IRS intended to delay the proposed
effective date of regulations that had been
proposed under section 6045(f). The final
regulations were published in the Federal
Register (TD 9270, 71 F.R. 39548-01) in
2006, obsoleting this notice.

Bulletin No. 2026–42 i October 13, 2026
Definition of Terms
Revenue rulings and revenue procedures
(hereinafter referred to as “rulings”) that
have an effect on previous rulings use the
following defined terms to describe the
effect:
Amplified describes a situation where
no change is being made in a prior pub-
lished position, but the prior position is
being extended to apply to a variation of
the fact situation set forth therein. Thus,
if an earlier ruling held that a principle
applied to A, and the new ruling holds that
the same principle also applies to B, the
earlier ruling is amplified. (Compare with
modified, below).
Clarified is used in those instances
where the language in a prior ruling is
being made clear because the language
has caused, or may cause, some confu-
sion. It is not used where a position in a
prior ruling is being changed.
Distinguished describes a situation
where a ruling mentions a previously pub-
lished ruling and points out an essential
difference between them.
Modified is used where the substance
of a previously published position is being
changed. Thus, if a prior ruling held that a
principle applied to A but not to B, and the
new ruling holds that it applies to both A
and B, the prior ruling is modified because
it corrects a published position. (Compare
with amplified and clarified, above).
Obsoleted describes a previously pub-
lished ruling that is not considered deter-
minative with respect to future transactions.
This term is most commonly used in a ruling
that lists previously published rulings that
are obsoleted because of changes in laws or
regulations. A ruling may also be obsoleted
because the substance has been included in
regulations subsequently adopted.
Revoked describes situations where the
position in the previously published ruling
is not correct and the correct position is
being stated in a new ruling.
Superseded describes a situation where
the new ruling does nothing more than
restate the substance and situation of a
previously published ruling (or rulings).
Thus, the term is used to republish under
the 1986 Code and regulations the same
position published under the 1939 Code
and regulations. The term is also used
when it is desired to republish in a single
ruling a series of situations, names, etc.,
that were previously published over a
period of time in separate rulings. If the
new ruling does more than restate the sub-
stance of a prior ruling, a combination of
terms is used. For example, modified and
superseded describes a situation where the
substance of a previously published ruling
is being changed in part and is continued
without change in part and it is desired to
restate the valid portion of the previously
published ruling in a new ruling that is
self contained. In this case, the previously
published ruling is first modified and then,
as modified, is superseded.
Supplemented is used in situations in
which a list, such as a list of the names of
countries, is published in a ruling and that
list is expanded by adding further names
in subsequent rulings. After the original
ruling has been supplemented several
times, a new ruling may be published that
includes the list in the original ruling and
the additions, and supersedes all prior rul-
ings in the series.
Suspended is used in rare situations
to show that the previous published rul-
ings will not be applied pending some
future action such as the issuance of new
or amended regulations, the outcome of
cases in litigation, or the outcome of a
Service study.
