                       TITLE 26--INTERNAL REVENUE
 
    CHAPTER I--INTERNAL REVENUE SERVICE, DEPARTMENT OF THE TREASURY 
                               (CONTINUED)
 
PART 1_INCOME TAXES--Table of Contents
 
Sec. 1.121-4  Special rules.

    (a) Property of deceased spouse--(1) In general. For purposes of 
satisfying the ownership and use requirements of section 121, a taxpayer 
is treated as owning and using property as the taxpayer's principal 
residence during any period that the taxpayer's deceased spouse owned 
and used the property as a principal residence before death if--
    (i) The taxpayer's spouse is deceased on the date of the sale or 
exchange of the property; and
    (ii) The taxpayer has not remarried at the time of the sale or 
exchange of the property.
    (2) Example. The provisions of this paragraph (a) are illustrated by 
the following example. The example assumes that Sec. 1.121-3 (relating 
to the reduced maximum exclusion) does not apply to the sale of the 
property. The example is as follows:

    Example. Taxpayer H has owned and used a house as his principal 
residence since 1987. H and W marry on July 1, 1999 and from that date 
they use H's house as their principal residence. H dies on August 15, 
2000, and W inherits the property. W sells the property on September 1, 
2000, at which time she has not remarried. Although W has owned and used 
the house for less than 2 years, W will be considered to have satisfied 
the ownership and use requirements of section 121 because W's period of 
ownership and use includes the period that H owned and used the property 
before death.

    (b) Property owned by spouse or former spouse--(1) Property 
transferred to individual from spouse or former spouse. If a taxpayer 
obtains property from a spouse or former spouse in a transaction 
described in section 1041(a), the period that the taxpayer owns the 
property will include the period that the spouse or former spouse owned 
the property.
    (2) Property used by spouse or former spouse. A taxpayer is treated 
as using property as the taxpayer's principal residence for any period 
that the taxpayer has an ownership interest in the property and the 
taxpayer's spouse or former spouse is granted use of the property under 
a divorce or separation instrument (as defined in section 71(b)(2)), 
provided that the spouse or former spouse uses the property as his or 
her principal residence.
    (c) Tenant-stockholder in cooperative housing corporation. A 
taxpayer who holds stock as a tenant-stockholder in a cooperative 
housing corporation (as those terms are defined in section 216(b)(1) and 
(2)) may be eligible to exclude gain under section 121 on the sale or 
exchange of the stock. In determining whether the taxpayer meets the 
requirements of section 121, the ownership requirements are applied to 
the holding of the stock and the use requirements are applied to the 
house or apartment that the taxpayer is entitled to occupy by reason of 
the taxpayer's stock ownership.
    (d) Involuntary conversions--(1) In general. For purposes of section 
121, the destruction, theft, seizure, requisition, or condemnation of 
property is treated as a sale of the property.
    (2) Application of section 1033. In applying section 1033 (relating 
to involuntary conversions), the amount realized from the sale or 
exchange of property used as the taxpayer's principal residence is 
treated as being the amount determined without regard to section 121, 
reduced by the amount of gain excluded from the taxpayer's gross income 
under section 121.
    (3) Property acquired after involuntary conversion. If the basis of 
the property acquired as a result of an involuntary conversion is 
determined (in whole or in part) under section 1033(b) (relating to the 
basis of property acquired through an involuntary conversion),

[[Page 515]]

then for purposes of satisfying the requirements of section 121, the 
taxpayer will be treated as owning and using the acquired property as 
the taxpayer's principal residence during any period of time that the 
taxpayer owned and used the converted property as the taxpayer's 
principal residence.
    (4) Example. The provisions of this paragraph (d) are illustrated by 
the following example:

    Example. (i) On February 18, 1999, fire destroys Taxpayer A's house 
which has an adjusted basis of $80,000. A had owned and used this 
property as her principal residence for 20 years prior to its 
destruction. A's insurance company pays A $400,000 for the house. A 
realizes a gain of $320,000 ($400,000--$80,000). On August 27, 1999, A 
purchases a new house at a cost of $100,000.
    (ii) Because the destruction of the house is treated as a sale for 
purposes of section 121, A will exclude $250,000 of the realized gain 
from A's gross income. For purposes of section 1033, the amount realized 
is then treated as being $150,000 ($400,000--$250,000) and the gain 
realized is $70,000 ($150,000 amount realized--$80,000 basis). A elects 
under section 1033 to recognize only $50,000 of the gain ($150,000 
amount realized--$100,000 cost of new house). The remaining $20,000 of 
gain is deferred and A's basis in the new house is $80,000 ($100,000 
cost--$20,000 gain not recognized).
    (iii) A will be treated as owning and using the new house as A's 
principal residence during the 20-year period that A owned and used the 
destroyed house.

    (e) Sales or exchanges of partial interests--(1) Partial interests 
other than remainder interests--(i) In general. Except as provided in 
paragraph (e)(2) of this section (relating to sales or exchanges of 
remainder interests), a taxpayer may apply the section 121 exclusion to 
gain from the sale or exchange of an interest in the taxpayer's 
principal residence that is less than the taxpayer's entire interest if 
the interest sold or exchanged includes an interest in the dwelling 
unit. For rules relating to the sale or exchange of vacant land, see 
Sec. 1.121-1(b)(3).
    (ii) Limitations--(A) Maximum limitation amount. For purposes of 
section 121(b)(1) and (2) (relating to the maximum limitation amount of 
the section 121 exclusion), sales or exchanges of partial interests in 
the same principal residence are treated as one sale or exchange. 
Therefore, only one maximum limitation amount of $250,000 ($500,000 for 
certain joint returns) applies to the combined sales or exchanges of the 
partial interests. In applying the maximum limitation amount to sales or 
exchanges that occur in different taxable years, a taxpayer may exclude 
gain from the first sale or exchange of a partial interest up to the 
taxpayer's full maximum limitation amount and may exclude gain from the 
sale or exchange of any other partial interest in the same principal 
residence to the extent of any remaining maximum limitation amount, and 
each spouse is treated as excluding one-half of the gain from a sale or 
exchange to which section 121(b)(2)(A) and Sec. 1.121-
2(a)(3)(i)(relating to the limitation for certain joint returns) apply.
    (B) Sale or exchange of more than one principal residence in 2-year 
period. For purposes of applying section 121(b)(3) (restricting the 
application of section 121 to only 1 sale or exchange every 2 years), 
each sale or exchange of a partial interest is disregarded with respect 
to other sales or exchanges of partial interests in the same principal 
residence, but is taken into account as of the date of the sale or 
exchange in applying section 121(b)(3) to that sale or exchange and the 
sale or exchange of any other principal residence.
    (2) Sales or exchanges of remainder interests--(i) In general. A 
taxpayer may elect to apply the section 121 exclusion to gain from the 
sale or exchange of a remainder interest in the taxpayer's principal 
residence.
    (ii) Limitations--(A) Sale or exchange of any other interest. If a 
taxpayer elects to exclude gain from the sale or exchange of a remainder 
interest in the taxpayer's principal residence, the section 121 
exclusion will not apply to a sale or exchange of any other interest in 
the residence that is sold or exchanged separately.
    (B) Sales or exchanges to related parties. This paragraph (e)(2) 
will not apply to a sale or exchange to any person that bears a 
relationship to the taxpayer that is described in section 267(b) or 
707(b).
    (iii) Election. The taxpayer makes the election under this paragraph 
(e)(2) by filing a return for the taxable year of

[[Page 516]]

the sale or exchange that does not include the gain from the sale or 
exchange of the remainder interest in the taxpayer's gross income. A 
taxpayer may make or revoke the election at any time before the 
expiration of a 3-year period beginning on the last date prescribed by 
law (determined without regard to extensions) for the filing of the 
return for the taxable year in which the sale or exchange occurred.
    (3) Example. The provisions of this paragraph (e) are illustrated by 
the following example:

    Example. In 1991 Taxpayer A buys a house that A uses as his 
principal residence. In 2004 A's friend B moves into A's house and A 
sells B a 50% interest in the house realizing a gain of $136,000. A may 
exclude the $136,000 of gain. In 2005 A sells his remaining 50% interest 
in the home to B realizing a gain of $138,000. A may exclude $114,000 
($250,000--$136,000 gain previously excluded) of the $138,000 gain from 
the sale of the remaining interest.

    (f) No exclusion for expatriates. The section 121 exclusion will not 
apply to any sale or exchange by an individual if the provisions of 
section 877(a) (relating to the treatment of expatriates) applies to the 
individual.
    (g) Election to have section not apply. A taxpayer may elect to have 
the section 121 exclusion not apply to a sale or exchange of property. 
The taxpayer makes the election by filing a return for the taxable year 
of the sale or exchange that includes the gain from the sale or exchange 
of the taxpayer's principal residence in the taxpayer's gross income. A 
taxpayer may make an election under this paragraph (g) to have section 
121 not apply (or revoke an election to have section 121 not apply) at 
any time before the expiration of a 3-year period beginning on the last 
date prescribed by law (determined without regard to extensions) for the 
filing of the return for the taxable year in which the sale or exchange 
occurred.
    (h) Residences acquired in rollovers under section 1034. If a 
taxpayer acquires property in a transaction that qualifies under section 
1034 (section 1034 property) for the nonrecognition of gain realized on 
the sale or exchange of another property and later sells or exchanges 
such property, in determining the period of the taxpayer's ownership and 
use of the property under section 121 the taxpayer may include the 
periods that the taxpayer owned and used the section 1034 property as 
the taxpayer's principal residence (and each prior residence taken into 
account under section 1223(7) in determining the holding period of the 
section 1034 property).
    (i) [Reserved]
    (j) Election to apply regulations retroactively. Taxpayers who would 
otherwise qualify under Sec. Sec. 1.121-1 through 1.121-4 to exclude 
gain from a sale or exchange of a principal residence before December 
24, 2002 but on or after May 7, 1997, may elect to apply Sec. Sec. 
1.121-1 through 1.121-4 for any years for which the period of limitation 
under section 6511 has not expired. The taxpayer makes the election 
under this paragraph (j) by filing a return for the taxable year of the 
sale or exchange that does not include the gain from the sale or 
exchange of the taxpayer's principal residence in the taxpayer's gross 
income. Taxpayers who have filed a return for the taxable year of the 
sale or exchange may elect to apply the provisions of these regulations 
for any years for which the period of limitation under section 6511 has 
not expired by filing an amended return.
    (k) Audit protection. The Internal Revenue Service will not 
challenge a taxpayer's position that a sale or exchange of a principal 
residence occurring before December 24, 2002 but on or after May 7, 
1997, qualifies for the section 121 exclusion if the taxpayer has made a 
reasonable, good faith effort to comply with the requirements of section 
121. Compliance with the provisions of the regulations project under 
section 121 (REG-105235-99 (2000-2 C.B. 447)) generally will be 
considered a reasonable, good faith effort to comply with the 
requirements of section 121.
    (l) Effective date. This section is applicable for sales and 
exchanges on or after December 24, 2002. For rules on electing to apply 
the provisions retroactively, see paragraph (j) of this section.
