Request for Comments on Energy Security Tax Credits for Manufacturing Under
Sections 48C and 45X

Notice 2022-47

SECTION 1. PURPOSE
The Department of the Treasury (Treasury Department) and the Internal
Revenue Service (IRS) plan to issue guidance regarding the advanced manufacturing
production credit under new § 45X (§ 45X credit) and the qualifying advanced energy
project credit under § 48C (§ 48C credit) of the Internal Revenue Code (Code), as
added and amended, by §§ 13502 and 13501, respectively, of Public Law 117-169, 136
Stat. 1818 (August 16, 2022), commonly known as the Inflation Reduction Act of 2022
(IRA). This notice requests general and specific comments on questions pertaining to
the implementation and administration of §§ 45X and 48C, which will help to inform the
development of guidance implementing §§ 45X and 48C.
SECTION 2. BACKGROUND
.01
Advanced Manufacturing Production Credit (§ 45X)
(1) Overview
Section 13502(a) of the IRA added new § 45X to the Code to establish the
advanced manufacturing production credit. Section 45X(a)(1) and (2) provide that, for
purposes of the general business credit under § 38 of the Code, the advanced
manufacturing production credit for any taxable year is an amount equal to the sum of

2

the credit amounts determined under § 45X(b) with respect to each eligible component
(as defined in § 45X(c)) produced by the taxpayer and sold by such taxpayer to an
unrelated person, but only if such production and sale is in a trade or business of the
taxpayer.
Section 45X(a)(3) provides rules regarding the sale of components to an
unrelated person, and generally provides a special rule that, for purposes of § 45X(a),
treats a taxpayer as selling components to an unrelated person if such component is
sold to such person by a person related to the taxpayer. Under § 45X(a)(3)(B), a
taxpayer may make an election in the form and manner prescribed by the Secretary of
the Treasury or her delegate (Secretary) to treat a sale of components by such taxpayer
to a related person as made to an unrelated person. As a condition of, and prior to, a
taxpayer making this election, the Secretary may require such information or registration
as the Secretary deems necessary for purposes of preventing duplication, fraud, or any
improper or excessive credit amount.
(2) Credit amounts
Section 45X(b)(1)(A) through (M) and § 45X(b)(2)(A) set forth the credit amounts
for each type of eligible component, which amounts, except for purposes of determining
the credit amount with respect to any applicable critical mineral, are subject to phase
out rules set forth in § 45X(b)(3). For any eligible component sold after December 31,
2029, the credit amount with respect to such component equals the product of the
amount determined under § 45X(b)(1) with respect to such component multiplied by the
phase out percentages under § 45X(b)(3)(B)(i) through (iv). In the case of an eligible
component sold during calendar year 2030, 2031, and 2032, the phase out percentages

3

are 75 percent, 50 percent, and 25 percent, respectively. In the case of an eligible
component sold after December 31, 2032, the phase out percentage is 0 percent.
Section 45X(b)(4) prescribes capacity limitations used to compute the credit
amount for eligible battery cells and battery modules under § 45X(b)(1)(K) and (L),
respectively. For purposes of computing the credit for these eligible components,
§ 45X(b)(4)(A) provides that the capacity determined with respect to a battery cell or
battery module must not exceed a capacity-to-power ratio of 100:1. Section
45X(b)(4)(B) defines the term “capacity-to-power-ratio” for this purpose as the ratio of
the capacity of a battery cell or battery module to the maximum discharge amount of
such cell or module.
(3) Eligible components
Section 45X(c) sets forth the different types of eligible components. Section
45X(c)(1)(A) provides that the term “eligible component” means any solar energy
component, wind energy component, inverter described in § 45X(c)(2)(B) through (G),
qualifying battery component, and applicable critical mineral. Section 45X(c)(1)(B)
clarifies that the term “eligible component” does not include any property that is
produced at a facility if the basis of any property that is part of such facility is taken into
account for purposes of the qualifying advanced energy project credit allowed under
§ 48C after August 16, 2022 (that is, the date of enactment of the IRA).
Section 45X(c)(2)(A) generally defines “inverter” as an end product that is
suitable to convert direct current electricity from 1 or more solar modules or certified
distributed wind energy systems into alternating current electricity. Section 45X(c)(2)(B)
through (G) define the following different types of eligible inverters: central inverter,

4

commercial inverter, distributed wind inverter, microinverter, residential inverter, and
utility inverter.
Section 45X(c)(3)(A) defines a “solar energy component” as photovoltaic cells,
photovoltaic wafers, polymeric backsheets, solar grade polysilicon, solar modules, and
torque tubes or structural fasteners. Section 45X(c)(3)(B) defines these different types
of eligible solar energy components as well as the term “solar tracker.”
Section 45X(c)(4)(A) defines “wind energy component” as blades, nacelles,
towers, offshore wind foundations, and related offshore wind vessels. Section
45X(c)(4)(B) defines these different types of eligible wind energy components.
Section 45X(c)(5)(A) defines a “qualifying battery component” as electrode active
materials, battery cells, and battery modules. Section 45X(c)(5)(B) defines these
different types of qualifying battery components.
Section 45X(c)(6) provides the following list of 50 minerals that when converted
or purified to specified purities are considered an “applicable critical mineral” for
purposes of the § 45X credit: aluminum, antimony, arsenic, barite, beryllium, bismuth,
cerium, cesium, chromium, cobalt, dysprosium, erbium, europium, fluorspar,
gadolinium, gallium, germanium, graphite, hafnium, holmium, indium, iridium,
lanthanum, lithium, lutetium, magnesium, manganese, neodymium, nickel, niobium,
palladium, platinum, praseodymium, rhodium, rubidium, ruthenium, samarium,
scandium, tantalum, tellurium, terbium, thulium, tin, titanium, tungsten, vanadium,
ytterbium, yttrium, zinc, and zirconium.

5

(4) Special rules
Section 45X(d) prescribes special rules applicable for the § 45X credit. Section
45X(d)(1) provides that persons are treated as related to each other if such persons
would be treated as a single employer under the regulations prescribed under the
common control rules of § 52(b) of the Code. Section 45X(d)(2) provides that sales of
eligible components are taken into account under § 45X only with respect to eligible
components the production of which is within the United States (including continental
shelf areas described in § 638(1) of the Code), or a U.S. territory (including continental
shelf areas described in § 638(2)). Section 45X(d)(3) directs the Secretary to
promulgate regulations adopting rules similar to the rules of § 52(d) to apportion credit
amounts between estates or trusts and their beneficiaries on the basis of the income of
the estates or trusts allocable to each and pass-thru any apportioned credit amounts to
the beneficiaries. Section 45X(d)(4) provides that for purposes of the § 45X credit, a
person is treated as having sold an eligible component to an unrelated person if such
component is integrated, incorporated, or assembled into another eligible component
which is sold to an unrelated person.
.02 Qualifying Advanced Energy Project Credit (§ 48C)
(1) Overview
Section 48C was originally enacted by § 1302(b) of the American Recovery and
Reinvestment Act of 2009, Public Law 111-5, Division B, Title I, Subtitle D, 123 Stat.
115, 345 (February 17, 2009), to provide an allocated credit for qualified investments in
qualifying advanced energy projects. For purposes of the investment tax credit
determined for any taxable year under § 46 of the Code, § 48C generally allows a

6

qualifying advanced energy project credit equal to 30 percent of a taxpayer’s qualified
investment for such taxable year with respect to any qualifying advanced energy project
of the taxpayer.
1
The amount treated as the qualified investment for all taxable years
with respect to a qualifying advanced energy project cannot exceed the amount
allocated to the project by the Secretary.
Section 48C has been amended several times, most recently by § 13501 of the
IRA. Section 13501(a) of the IRA adds new § 48C(e) to the Code to extend the § 48C
credit to provide an additional credit allocation of $10 billion. Section 13501(b) of the
IRA modifies the definition of a “qualifying advanced energy project” contained in
§ 48C(c)(1)(A). Section 13501(c) and (d) of the IRA make conforming amendments to
§ 48C(c)(2)(A) and (f). The amendments made by § 13501 of the IRA are effective on
January 1, 2023. See § 13501(e) of the IRA.
(2) New § 48C(e)
Section 48C(e)(1) directs the Secretary to establish a program to consider and
award certifications for qualified investments eligible for § 48C credits to qualifying
advanced energy project sponsors.
Section 48C(e)(2) provides that the total amount of § 48C credits that may be
allocated under such program cannot exceed $10 billion, of which no greater than
$6 billion may be allocated to qualified investments which are not located within one of
the following census tracts described in § 45(b)(11)(B)(iii):
(a) A census tract in which a coal mine has closed after December 31, 1999.

1
Section 48C(e)(4)(A) provides a base credit rate of 6 precent for allocations under § 48C(e). The base
credit rate is increased to 30 precent for any project that satisfies the prevailing wage requirements of
§ 48C(e)(5)(A) and the apprenticeship requirements of § 48C(e)(6). See Notice 2022-51 requesting
comments on prevailing wage and apprenticeship requirements.

7

(b) A census tract in which a coal-fired electric generating unit has been retired
after December 31, 2009.
(c) A census tract directly adjoining such a census tract described in (a) or (b)
and, prior to August 16, 2022 (the date of enactment of § 48C(e)), had no project that
received a certification and allocation of credits under § 48C(d).
Section 48C(e)(3)(A) provides that each applicant for certification must submit an
application at such time and containing such information as the Secretary may require.
Section 48C(e)(3)(B) provides that each applicant for certification has 2 years from the
date of acceptance by the Secretary of the application to provide to the Secretary
evidence that the requirements of the certification have been met.
Section 48C(e)(3)(C) provides that an applicant who receives a certification has
2 years from the date of issuance of the certification to place the project in service and
to notify the Secretary that such project has been so placed in service. If the project is
not placed in service within the two year period, then the certification is no longer valid.
If any certification is revoked under § 48C(e)(3), the total amount of the credits that may
be allocated under § 48C(e)(2) is increased by the amount of § 48C credit with respect
to such revoked certification.
Section 48C(e)(3)(D) provides that in the case of an applicant which receives a
certification, if the Secretary determines that the project has been placed in service at a
location that is materially different than the location specified in the application for such
project, the certification is no longer valid.

8

Section 48C(e)(7) provides that the Secretary must, upon making a certification
under § 48C(e), publicly disclose the identity of the applicant and the amount of the
§ 48C credit with respect to such applicant.
(3) Amendments to § 48C(c)(1)(A)
As amended by the IRA, § 48C(c)(1)(A) defines the term “qualifying advanced
energy project” as one of the three following project types, any portion of the qualified
investment of which is certified by the Secretary under § 48C(e) as eligible for a § 48C
credit:
(i) A project that re-equips, expands, or establishes an industrial or
manufacturing facility for the production or recycling of one of the following nine
property types:
(I) Property designed to be used to produce energy from the sun,
water, wind, geothermal deposits or other renewable resources.
(II) Fuel cells, microturbines, or energy storage systems and
components.
(III) Electric grid modernization equipment or components.
(IV) Property designed to capture, remove, use, or sequester carbon
oxide emissions.
(V) Equipment designed to refine, electrolyze, or blend any fuel,
chemical, or product which is renewable or low-carbon and low-emission.
(VI) Property designed to produce energy conservation technologies
(including residential, commercial, and industrial applications).

9

(VII) Light, medium, or heavy-duty electric or fuel cell vehicles, as well
as technologies, components, or materials for such vehicles, and associated
charging or refueling infrastructure.
(VIII) Hybrid vehicles with a gross vehicle weight rating of not less than
14,000 pounds, as well as technologies, components, or materials for such
vehicles.
(IX) Other advanced energy property designed to reduce greenhouse
gas emissions as may be determined by the Secretary.
(ii) A project that re-equips an industrial or manufacturing facility with
equipment designed to reduce greenhouse gas emissions by at least 20 percent
through the installation of (I) low- or zero-carbon process heat systems, (II)
carbon capture, transport, utilization, and storage systems, (III) energy efficiency
and reduction in waste from industrial processes, or (IV) any other industrial
technology designed to reduce greenhouse gas emissions, as determined by the
Secretary.
(iii) A project that re-equips, expands, or establishes an industrial facility
for the processing, refining, or recycling of critical materials (as defined in §
7002(a) of the Energy Act of 2020 (30 USC § 1606(a)).
Section 48C(c)(2)(A) defines “eligible property” as any property that is necessary
for the production or recycling of property described in § 48C(c)(1)(A)(i), re-equipping an
industrial or manufacturing facility described in § 48C(c)(1)(A)(ii), or re-equipping,
expanding, or establishing an industrial facility described in § 48C(c)(1)(A)(iii).

10

(4) Denial of Double Benefit
As amended by § 13501(c) of the IRA, § 48C(f) provides that a § 48C credit is
not allowed for a qualified investment for which a credit is allowed under §§ 48, 48A,
48B, 48E, 45Q or 45V.
SECTION 3. REQUEST FOR COMMENTS
The Treasury Department and the IRS request comments on issues arising from
new § 45X and the amendments made by the IRA to § 48C that should be addressed in
