                       TITLE 26--INTERNAL REVENUE
 
    CHAPTER I--INTERNAL REVENUE SERVICE, DEPARTMENT OF THE TREASURY 
                               (CONTINUED)
 
PART 1_INCOME TAXES--Table of Contents
 
Sec. 1.121-1  Exclusion of gain from sale or exchange of a principal 
residence.

    (a) In general. Section 121 provides that, under certain 
circumstances, gross income does not include gain realized on the sale 
or exchange of property that was owned and used by a taxpayer as the 
taxpayer's principal residence. Subject to the other provisions of 
section 121, a taxpayer may exclude gain only if, during the 5-year 
period ending on the date of the sale or exchange, the taxpayer owned 
and used the property as the taxpayer's principal residence for periods 
aggregating 2 years or more.
    (b) Residence--(1) In general. Whether property is used by the 
taxpayer as the taxpayer's residence depends upon all the facts and 
circumstances. A property used by the taxpayer as the taxpayer's 
residence may include a houseboat, a house trailer, or the house or

[[Page 504]]

apartment that the taxpayer is entitled to occupy as a tenant-
stockholder in a cooperative housing corporation (as those terms are 
defined in section 216(b)(1) and (2)). Property used by the taxpayer as 
the taxpayer's residence does not include personal property that is not 
a fixture under local law.
    (2) Principal residence. In the case of a taxpayer using more than 
one property as a residence, whether property is used by the taxpayer as 
the taxpayer's principal residence depends upon all the facts and 
circumstances. If a taxpayer alternates between 2 properties, using each 
as a residence for successive periods of time, the property that the 
taxpayer uses a majority of the time during the year ordinarily will be 
considered the taxpayer's principal residence. In addition to the 
taxpayer's use of the property, relevant factors in determining a 
taxpayer's principal residence, include, but are not limited to--
    (i) The taxpayer's place of employment;
    (ii) The principal place of abode of the taxpayer's family members;
    (iii) The address listed on the taxpayer's federal and state tax 
returns, driver's license, automobile registration, and voter 
registration card;
    (iv) The taxpayer's mailing address for bills and correspondence;
    (v) The location of the taxpayer's banks; and
    (vi) The location of religious organizations and recreational clubs 
with which the taxpayer is affiliated.
    (3) Vacant land--(i) In general. The sale or exchange of vacant land 
is not a sale or exchange of the taxpayer's principal residence unless--
    (A) The vacant land is adjacent to land containing the dwelling unit 
of the taxpayer's principal residence;
    (B) The taxpayer owned and used the vacant land as part of the 
taxpayer's principal residence;
    (C) The taxpayer sells or exchanges the dwelling unit in a sale or 
exchange that meets the requirements of section 121 within 2 years 
before or 2 years after the date of the sale or exchange of the vacant 
land; and
    (D) The requirements of section 121 have otherwise been met with 
respect to the vacant land.
    (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), the sale or exchange of the dwelling unit 
and the vacant land 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 vacant land and 
the dwelling unit. In applying the maximum limitation amount to sales or 
exchanges that occur in different taxable years, gain from the sale or 
exchange of the dwelling unit, up to the maximum limitation amount under 
section 121(b)(1) or (2), is excluded first 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. If a dwelling unit and vacant land are sold or exchanged in 
separate transactions that qualify for the section 121 exclusion under 
this paragraph (b)(3), each of the transactions is disregarded in 
applying section 121(b)(3) (restricting the application of section 121 
to only 1 sale or exchange every 2 years) to the other transactions but 
is taken into account as a sale or exchange of a principal residence on 
the date of the transaction in applying section 121(b)(3) to that 
transaction and the sale or exchange of any other principal residence.
    (C) Sale or exchange of vacant land before dwelling unit. If the 
sale or exchange of the dwelling unit occurs in a later taxable year 
than the sale or exchange of the vacant land and after the date 
prescribed by law (including extensions) for the filing of the return 
for the taxable year of the sale or exchange of the vacant land, any 
gain from the sale or exchange of the vacant land must be treated as 
taxable on the taxpayer's return for the taxable year of the sale or 
exchange of the vacant land. If the taxpayer has reported gain from the 
sale or exchange of the vacant land as taxable, after satisfying the 
requirements of this paragraph (b)(3) the

[[Page 505]]

taxpayer may claim the section 121 exclusion with regard to the sale or 
exchange of the vacant land (for any period for which the period of 
limitation under section 6511 has not expired) by filing an amended 
return.
    (4) Examples. The provisions of this paragraph (b) are illustrated 
by the following examples:

    Example 1. Taxpayer A owns 2 residences, one in New York and one in 
Florida. From 1999 through 2004, he lives in the New York residence for 
7 months and the Florida residence for 5 months of each year. In the 
absence of facts and circumstances indicating otherwise, the New York 
residence is A's principal residence. A would be eligible for the 
section 121 exclusion of gain from the sale or exchange of the New York 
residence, but not the Florida residence.
    Example 2. Taxpayer B owns 2 residences, one in Virginia and one in 
Maine. During 1999 and 2000, she lives in the Virginia residence. During 
2001 and 2002, she lives in the Maine residence. During 2003, she lives 
in the Virginia residence. B's principal residence during 1999, 2000, 
and 2003 is the Virginia residence. B's principal residence during 2001 
and 2002 is the Maine residence. B would be eligible for the 121 
exclusion of gain from the sale or exchange of either residence (but not 
both) during 2003.
    Example 3. In 1991 Taxpayer C buys property consisting of a house 
and 10 acres that she uses as her principal residence. In May 2005 C 
sells 8 acres of the land and realizes a gain of $110,000. C does not 
sell the dwelling unit before the due date for filing C's 2005 return, 
therefore C is not eligible to exclude the $110,000 of gain. In March 
2007 C sells the house and remaining 2 acres realizing a gain of 
$180,000 from the sale of the house. C may exclude the $180,000 of gain. 
Because the sale of the 8 acres occurred within 2 years from the date of 
the sale of the dwelling unit, the sale of the 8 acres is treated as a 
sale of the taxpayer's principal residence under paragraph (b)(3) of 
this section. C may file an amended return for 2005 to claim an 
exclusion for $70,000 ($250,000-$180,000 gain previously excluded) of 
the $110,000 gain from the sale of the 8 acres.
    Example 4. In 1998 Taxpayer D buys a house and 1 acre that he uses 
as his principal residence. In 1999 D buys 29 acres adjacent to his 
house and uses the vacant land as part of his principal residence. In 
2003 D sells the house and 1 acre and the 29 acres in 2 separate 
transactions. D sells the house and 1 acre at a loss of $25,000. D 
realizes $270,000 of gain from the sale of the 29 acres. D may exclude 
the $245,000 gain from the 2 sales.

    (c) Ownership and use requirements--(1) In general. The requirements 
of ownership and use for periods aggregating 2 years or more may be 
satisfied by establishing ownership and use for 24 full months or for 
730 days (365 x 2). The requirements of ownership and use may be 
satisfied during nonconcurrent periods if both the ownership and use 
tests are met during the 5-year period ending on the date of the sale or 
exchange.
    (2) Use. (i) In establishing whether a taxpayer has satisfied the 2-
year use requirement, occupancy of the residence is required. However, 
short temporary absences, such as for vacation or other seasonal absence 
(although accompanied with rental of the residence), are counted as 
periods of use.
    (ii) Determination of use during periods of out-of-residence care. 
If a taxpayer has become physically or mentally incapable of self-care 
and the taxpayer sells or exchanges property that the taxpayer owned and 
used as the taxpayer's principal residence for periods aggregating at 
least 1 year during the 5-year period preceding the sale or exchange, 
the taxpayer is treated as using the property as the taxpayer's 
principal residence for any period of time during the 5-year period in 
which the taxpayer owns the property and resides in any facility 
(including a nursing home) licensed by a State or political subdivision 
to care for an individual in the taxpayer's condition.
    (3) Ownership--(i) Trusts. If a residence is owned by a trust, for 
the period that a taxpayer is treated under sections 671 through 679 
(relating to the treatment of grantors and others as substantial owners) 
as the owner of the trust or the portion of the trust that includes the 
residence, the taxpayer will be treated as owning the residence for 
purposes of satisfying the 2-year ownership requirement of section 121, 
and the sale or exchange by the trust will be treated as if made by the 
taxpayer.
    (ii) Certain single owner entities. If a residence is owned by an 
eligible entity (within the meaning of Sec. 301.7701-3(a) of this 
chapter) that has a single owner and is disregarded for federal tax 
purposes as an entity separate from its owner under Sec. 301.7701-3 of 
this chapter, the owner will be treated as owning the residence for 
purposes of satisfying the

[[Page 506]]

2-year ownership requirement of section 121, and the sale or exchange by 
the entity will be treated as if made by the owner.
    (4) Examples. The provisions of this paragraph (c) are illustrated 
by the following examples. The examples assume that Sec. 1.121-3 
(relating to the reduced maximum exclusion) does not apply to the sale 
of the property. The examples are as follows:

    Example 1. Taxpayer A has owned and used his house as his principal 
residence since 1986. On January 31, 1998, A moves to another state. A 
rents his house to tenants from that date until April 18, 2000, when he 
sells it. A is eligible for the section 121 exclusion because he has 
owned and used the house as his principal residence for at least 2 of 
the 5 years preceding the sale.
    Example 2. Taxpayer B owns and uses a house as her principal 
residence from 1986 to the end of 1997. On January 4, 1998, B moves to 
another state and ceases to use the house. B's son moves into the house 
in March 1999 and uses the residence until it is sold on July 1, 2001. B 
may not exclude gain from the sale under section 121 because she did not 
use the property as her principal residence for at least 2 years out of 
the 5 years preceding the sale.
    Example 3. Taxpayer C lives in a townhouse that he rents from 1993 
through 1996. On January 18, 1997, he purchases the townhouse. On 
February 1, 1998, C moves into his daughter's home. On May 25, 2000, 
while still living in his daughter's home, C sells his townhouse. The 
section 121 exclusion will apply to gain from the sale because C owned 
the townhouse for at least 2 years out of the 5 years preceding the sale 
(from January 19, 1997 until May 25, 2000) and he used the townhouse as 
his principal residence for at least 2 years during the 5-year period 
preceding the sale (from May 25, 1995 until February 1, 1998).
    Example 4. Taxpayer D, a college professor, purchases and moves into 
a house on May 1, 1997. He uses the house as his principal residence 
continuously until September 1, 1998, when he goes abroad for a 1-year 
sabbatical leave. On October 1, 1999, 1 month after returning from the 
leave, D sells the house. Because his leave is not considered to be a 
short temporary absence under paragraph (c)(2) of this section, the 
period of the sabbatical leave may not be included in determining 
whether D used the house for periods aggregating 2 years during the 5-
year period ending on the date of the sale. Consequently, D is not 
entitled to exclude gain under section 121 because he did not use the 
residence for the requisite period.
    Example 5. Taxpayer E purchases a house on February 1, 1998, that he 
uses as his principal residence. During 1998 and 1999, E leaves his 
residence for a 2-month summer vacation. E sells the house on March 1, 
2000. Although, in the 5-year period preceding the date of sale, the 
total time E used his residence is less than 2 years (21 months), the 
section 121 exclusion will apply to gain from the sale of the residence 
because, under paragraph (c)(2) of this section, the 2-month vacations 
are short temporary absences and are counted as periods of use in 
determining whether E used the residence for the requisite period.

    (d) Depreciation taken after May 6, 1997--(1) In general. The 
section 121 exclusion does not apply to so much of the gain from the 
sale or exchange of property as does not exceed the portion of the 
depreciation adjustments (as defined in section 1250(b)(3)) attributable 
to the property for periods after May 6, 1997. Depreciation adjustments 
allocable to any portion of the property to which the section 121 
exclusion does not apply under paragraph (e) of this section are not 
taken into account for this purpose.
    (2) Example. The provisions of this paragraph (d) are illustrated by 
the following example:

    Example. On July 1, 1999, Taxpayer A moves into a house that he owns 
and had rented to tenants since July 1, 1997. A took depreciation 
deductions totaling $14,000 for the period that he rented the property. 
After using the residence as his principal residence for 2 full years, A 
sells the property on August 1, 2001. A's gain realized from the sale is 
$40,000. A has no other section 1231 or capital gains or losses for 
2001. Only $26,000 ($40,000 gain realized--$14,000 depreciation 
deductions) may be excluded under section 121. Under section 121(d)(6) 
and paragraph (d)(1) of this section, A must recognize $14,000 of the 
gain as unrecaptured section 1250 gain within the meaning of section 
1(h).

    (e) Property used in part as a principal residence--(1) Allocation 
required. Section 121 will not apply to the gain allocable to any 
portion (separate from the dwelling unit) of property sold or exchanged 
with respect to which a taxpayer does not satisfy the use requirement. 
Thus, if a portion of the property was used for residential purposes and 
a portion of the property (separate from the dwelling unit) was used for 
non-residential purposes, only the gain allocable to the residential 
portion is excludable under section 121. No allocation is required if 
both the residential

[[Page 507]]

and non-residential portions of the property are within the same 
dwelling unit. However, section 121 does not apply to the gain allocable 
to the residential portion of the property to the extent provided by 
paragraph (d) of this section.
    (2) Dwelling unit. For purposes of this paragraph (e), the term 
dwelling unit has the same meaning as in section 280A(f)(1), but does 
not include appurtenant structures or other property.
    (3) Method of allocation. For purposes of determining the amount of 
gain allocable to the residential and non-residential portions of the 
property, the taxpayer must allocate the basis and the amount realized 
between the residential and the non-residential portions of the property 
using the same method of allocation that the taxpayer used to determine 
depreciation adjustments (as defined in section 1250(b)(3)), if 
applicable.
    (4) Examples. The provisions of this paragraph (e) are illustrated 
by the following examples:

    Example 1. Non-residential use of property not within the dwelling 
unit. (i) Taxpayer A owns a property that consists of a house, a stable 
and 35 acres. A uses the stable and 28 acres for non-residential 
purposes for more than 3 years during the 5-year period preceding the 
sale. A uses the entire house and the remaining 7 acres as his principal 
residence for at least 2 years during the 5-year period preceding the 
sale. For periods after May 6, 1997, A claims depreciation deductions of 
$9,000 for the non-residential use of the stable. A sells the entire 
property in 2004, realizing a gain of $24,000. A has no other section 
1231 or capital gains or losses for 2004.
    (ii) Because the stable and the 28 acres used in the business are 
separate from the dwelling unit, the allocation rules under this 
paragraph (e) apply and A must allocate the basis and amount realized 
between the portion of the property that he used as his principal 
residence and the portion of the property that he used for non-
residential purposes. A determines that $14,000 of the gain is allocable 
to the non-residential-use portion of the property and that $10,000 of 
the gain is allocable to the portion of the property used as his 
residence. A must recognize the $14,000 of gain allocable to the non-
residential-use portion of the property ($9,000 of which is unrecaptured 
section 1250 gain within the meaning of section 1(h), and $5,000 of 
which is adjusted net capital gain). A may exclude $10,000 of the gain 
from the sale of the property.
    Example 2. Non-residential use of property not within the dwelling 
unit and rental of the entire property. (i) In 1998 Taxpayer B buys a 
property that includes a house, a barn, and 2 acres. B uses the house 
and 2 acres as her principal residence and the barn for an antiques 
business. In 2002, B moves out of the house and rents it to tenants. B 
sells the property in 2004, realizing a gain of $21,000. Between 1998 
and 2004 B claims depreciation deductions of $4,800 attributable to the 
antiques business. Between 2002 and 2004 B claims depreciation 
deductions of $3,000 attributable to the house. B has no other section 
1231 or capital gains or losses for 2004.
    (ii) Because the portion of the property used in the antiques 
business is separate from the dwelling unit, the allocation rules under 
this paragraph (e) apply. B must allocate basis and amount realized 
between the portion of the property that she used as her principal 
residence and the portion of the property that she used for non-
residential purposes. B determines that $4,000 of the gain is allocable 
to the non-residential portion of the property and that $17,000 of the 
gain is allocable to the portion of the property that she used as her 
principal residence.
    (iii) B must recognize the $4,000 of gain allocable to the non-
residential portion of the property (all of which is unrecaptured 
section 1250 gain within the meaning of section 1(h)). In addition, the 
section 121 exclusion does not apply to the gain allocable to the 
residential portion of the property to the extent of the depreciation 
adjustments attributable to the residential portion of the property for 
periods after May 6, 1997 ($3,000). Therefore, B may exclude $14,000 of 
the gain from the sale of the property.
    Example 3. Non-residential use of a separate dwelling unit. (i) In 
2002 Taxpayer C buys a 3-story townhouse and converts the basement 
level, which has a separate entrance, into a separate apartment by 
installing a kitchen and bathroom and removing the interior stairway 
that leads from the basement to the upper floors. After the conversion, 
the property constitutes 2 dwelling units within the meaning of 
paragraph (e)(2) of this section. C uses the first and second floors of 
the townhouse as his principal residence and rents the basement level to 
tenants from 2003 to 2007. C claims depreciation deductions of $2,000 
for that period with respect to the basement apartment. C sells the 
entire property in 2007, realizing gain of $18,000. C has no other 
section 1231 or capital gains or losses for 2007.
    (ii) Because the basement apartment and the upper floors of the 
townhouse are separate dwelling units, C must allocate the gain between 
the portion of the property that he used as his principal residence and 
the portion of the property that he used for non-residential purposes 
under paragraph (e) of this section. After allocating the basis and the

[[Page 508]]

amount realized between the residential and non-residential portions of 
the property, C determines that $6,000 of the gain is allocable to the 
non-residential portion of the property and that $12,000 of the gain is 
allocable to the portion of the property used as his residence. C must 
recognize the $6,000 of gain allocable to the non-residential portion of 
the property ($2,000 of which is unrecaptured section 1250 gain within 
the meaning of section 1(h), and $4,000 of which is adjusted net capital 
gain). C may exclude $12,000 of the gain from the sale of the property.
    Example 4. Separate dwelling unit converted to residential use. The 
facts are the same as in Example 3 except that in 2007 C incorporates 
the basement of the townhouse into his principal residence by 
eliminating the kitchen and building a new interior stairway to the 
upper floors. C uses all 3 floors of the townhouse as his principal 
residence for 2 full years and sells the townhouse in 2010, realizing a 
gain of $20,000. Under section 121(d)(6) and paragraph (d) of this 
section, C must recognize $2,000 of the gain as unrecaptured section 
1250 gain within the meaning of section 1(h). Because C used the entire 
3 floors of the townhouse as his principal residence for 2 of the 5 
years preceding the sale of the property, C may exclude the remaining 
$18,000 of the gain from the sale of the house.
    Example 5. Non-residential use within the dwelling unit, property 
depreciated. Taxpayer D, an attorney, buys a house in 2003. The house 
constitutes a single dwelling unit but D uses a portion of the house as 
a law office. D claims depreciation deductions of $2,000 during the 
period that she owns the house. D sells the house in 2006, realizing a 
gain of $13,000. D has no other section 1231 or capital gains or losses 
for 2006. Under section 121(d)(6) and paragraph (d) of this section, D 
must recognize $2,000 of the gain as unrecaptured section 1250 gain 
within the meaning of section 1(h). D may exclude the remaining $11,000 
of the gain from the sale of her house because, under paragraph (e)(1) 
of this section, she is not required to allocate gain to the business 
use within the dwelling unit.
    Example 6. Non-residential use within the dwelling unit, property 
not depreciated. The facts are the same as in Example 5, except that D 
is not entitled to claim any depreciation deductions with respect to her 
business use of the house. D may exclude $13,000 of the gain from the 
sale of her house because, under paragraph (e)(1) of this section, she 
is not required to allocate gain to the business use within the dwelling 
unit.

    (f) Effective date. This section is applicable for sales and 
exchanges on or after Decmeber 24, 2002. For rules on electing to apply 
the provisions of this section retroactively, see Sec. 1.121-4(j).
