Part I

Sections 6012, 6651, 6673

Rev. Rul. 2006-17

PURPOSE

The Service is aware that some taxpayers are attempting to reduce their federal
income tax liability by filing a return or submitting documents to the Service with the
phrase “nunc pro tunc” written or stamped on the face of the return or document, and
asserting that the phrase has some legal effect. The Service is also aware that some
promoters, including return preparers, are advising or recommending that taxpayers
take this frivolous position. Some promoters market a package, kit or other materials
that claim to show taxpayers how they can avoid paying income taxes based on this
and other meritless arguments.
This revenue ruling emphasizes to taxpayers, promoters, and return preparers
that inserting the phrase “nunc pro tunc” on a return or other document submitted to the
Service has no legal effect and does not validate an invalid return, make a delinquent
return timely, invalidate a signature, create a claim for refund of taxes previously paid,
or reduce one’s federal tax liability. Any argument that the inclusion of the phrase “nunc
pro tunc” on a return or other document submitted to the Service has any legal effect
has no merit and is frivolous.
The Service is committed to identifying taxpayers who attempt to avoid their
federal tax obligations by taking frivolous positions. The Service will take vigorous

enforcement action against these taxpayers and against promoters and return preparers
who assist taxpayers in taking these frivolous positions. Frivolous returns and other
similar documents submitted to the Service are processed through the Service’s
Frivolous Return Program. As part of this program, the Service confirms whether
taxpayers who take frivolous positions have filed all of their required tax returns,
computes the correct amount of tax and interest due, and determines whether civil or
criminal penalties should apply. The Service also determines whether civil or criminal
penalties should apply to return preparers, promoters, and others who assist taxpayers
in taking frivolous positions, and recommends whether an injunction should be sought to
halt these activities. Other information about frivolous tax positions is available on the
Service website at
www.irs.gov.

ISSUE
Whether inclusion of the phrase “nunc pro tunc” on a return or other document
filed with the Service has any legal effect.
FACTS
Some taxpayers file returns or other documents with the Service that have the
phrase “nunc pro tunc” stamped or written on the face of the return or document. These
taxpayers assert that the phrase “nunc pro tunc” has some legal effect in reducing,
eliminating, or altering in some way their federal income tax liability or other obligations
under the tax laws.

LAW AND ANALYSIS
The phrase “nunc pro tunc,” a Latin phrase translated as “now for then,” denotes
that an act has retroactive legal effect through a court’s inherent power.
Black’s Law
Dictionary 1097 (8
th
ed. 2004). When a document is signed “nunc pro tunc” as of a
specified date, it means that a thing is now done which should have been done on the
specified date. 56 Am. Jur. 2d Motions, Rules, and Orders § 58, at 45 (2000).
The term “nunc pro tunc” also describes a later record entry of a previous action
that is intended to have effect as of the date of the action itself. Black’s Law Dictionary
1097. The inclusion of the phrase “nunc pro tunc” on the face of the return form or in
other documents submitted to the Service has no legal effect, and does not validate an
invalid return, make an untimely return timely, invalidate a signature, create a claim for
refund of taxes previously paid, or reduce one’s federal tax liability.
To the extent taxpayers are attempting to validate an otherwise invalid return by
writing or stamping the phrase “nunc pro tunc” on the face of a return or in attached
documents, this phrase has no validating effect. For a document to qualify as a valid
return, it must contain sufficient data to calculate tax liability, it must purport to be a
return, there must be an honest and reasonable attempt to satisfy the requirements of
the tax law, and the taxpayer must execute the return under penalties of perjury. Beard
v. Commissioner, 82 T.C. 766 (1984), aff’d, 793 F.2d 139 (6
th
Cir. 1986). The inclusion
of the phrase “nunc pro tunc” on the face of the return form or in the attachments does
not provide any further information sufficient to calculate tax liability, or to satisfy any

other requirements of the tax law. Accordingly, it does not validate an otherwise invalid
return.
HOLDING
Inclusion of the phrase “nunc pro tunc” on a return or other document submitted
to the Service has no legal effect and is therefore frivolous.
CIVIL AND CRIMINAL PENALTIES

The Service will challenge the claims of individuals who attempt to avoid or
evade their federal tax liability. In addition to liability for the tax due plus statutory
interest, taxpayers who fail to file valid returns or pay tax based on the argument that
the inclusion of the phrase “nunc pro tunc” on the face of their return or other document
submitted to the Service has some legal effect, face substantial civil and criminal
penalties. Potentially applicable civil penalties include: (1) the section 6662 accuracy-
related penalties, which are generally equal to 20 percent of the amount of tax the
taxpayer should have paid; (2) the section 6663 penalty for civil fraud, which is equal to
75 percent of the amount of taxes the taxpayer should have paid; (3) a $500 penalty
imposed under section 6702 when the taxpayer files a document that purports to be a
return but that contains a frivolous position or suggests a desire by the taxpayer to delay
or impede the administration of Federal income tax laws; (4) the section 6651 additions
to tax for failure to file a return, failure to pay the tax owed, and fraudulent failure to file a
return; and (5) a penalty of up to $25,000 under section 6673 if the taxpayer makes
frivolous arguments in the United States Tax Court.

Taxpayers relying on these frivolous positions also may face criminal prosecution
under: (1) section 7201 for attempting to evade or defeat tax, the penalty for which is a
significant fine and imprisonment for up to 5 years; (2) section 7203 for willful failure to
file a return under section 7203, the penalty for which is a significant fine and
imprisonment for up to a year; and (3) section 7206 for making false statements on a
return, statement, or other document, the penalty for which is a significant fine and
imprisonment for up to 3 years; and (4) any other penalties pursuant to applicable
provisions of federal law.
Persons, including return preparers, who promote these frivolous positions and
those who assist taxpayers in claiming tax benefits based on frivolous positions may
face civil and criminal penalties and also may be enjoined by a court pursuant to
sections 7407 and 7408. Potential penalties include: (1) a $250 penalty under section
6694 for each return or claim for refund prepared by an income tax return preparer who
knew or should have known that the taxpayer’s position was frivolous (or $1,000 for
each return or claim for refund if the return preparer’s actions were willful, intentional or
reckless); (2) a penalty under section 6700 for promoting abusive tax shelters; (3) a
$1,000 penalty under section 6701 for aiding and abetting the understatement of tax;
and (4) criminal prosecution under section 7206, for which the penalty is a significant
fine and imprisonment for up to 3 years, for assisting or advising about the preparation
of a false return or other document under the internal revenue laws.
