A is unemployed and owns a townhouse that she has owned and used as her principal residence since 2003. In 2004 A obtains a job that is 54 miles from her townhouse, and she sells the townhouse. Because the distance between A's new place of employment and the townhouse is at least 50 miles, the sale is within the safe harbor of paragraph (c)(2) of this section and A is entitled to claim a reduced maximum exclusion under section 121(c)(2).
B is an officer in the United States Air Force stationed in Florida. B purchases a house in Florida in 2002. In May 2003 B moves out of his house to take a 3-year assignment in Germany. B sells his house in January 2004. Because B's new place of employment in Germany is at least 50 miles farther from the residence sold than is B's former place of employment in Florida, the sale is within the safe harbor of paragraph (c)(2) of this section and B is entitled to claim a reduced maximum exclusion under section 121(c)(2).
C is employed by Employer R at R's Philadelphia office. C purchases a house in February 2002 that is 35 miles from R's Philadelphia office. In May 2003 C begins a temporary assignment at R's Wilmington office that is 72 miles from C's house, and moves out of the house. In June 2005 C is assigned to work in R's London office. C sells her house in August 2005 as a result of the assignment to London. The sale of the house is not within the safe harbor of paragraph (c)(2) of this section by reason of the change in place of employment from Philadelphia to Wilmington because the Wilmington office is not 50 miles farther from C's house than is the Philadelphia office. Furthermore, the sale is not within the safe harbor by reason of the change in place of employment to London because C is not using the house as her principal residence when she moves to London. However, C is entitled to claim a reduced maximum exclusion under section 121(c)(2) because, under the facts and circumstances, the primary reason for the sale is the change in C's place of employment.
In July 2003 D, who works as an emergency medicine physician, buys a condominium that is 5 miles from her place of employment and uses it as her principal residence. In February 2004, D obtains a job that is located 51 miles from D's condominium. D may be called in to work unscheduled hours and, when called, must be able to arrive at work quickly. Because of the demands of the new job, D sells her condominium and buys a townhouse that is 4 miles from her new place of employment. Because D's new place of employment is only 46 miles farther from the condominium than is D's former place of employment, the sale is not within the safe harbor of paragraph (c)(2) of this section. However, D is entitled to claim a reduced maximum exclusion under section 121(c)(2) because, under the facts and circumstances, the primary reason for the sale is the change in D's place of employment.
In 2003 A buys a house that she uses as her principal residence. A is injured in an accident and is unable to care for herself. A sells her house in 2004 and moves in with her daughter so that the daughter can provide the care that A requires as a result of her injury. Because, under the facts and circumstances, the primary reason for the sale of A's house is A's health, A is entitled to claim a reduced maximum exclusion under section 121(c)(2).
H's father has a chronic disease. In 2003 H and W purchase a house that they use as their principal residence. In 2004 H and W sell their house in order to move into the house of H's father so that they can provide the care he requires as a result of his disease. Because, under the facts and circumstances, the primary reason for the sale of their house is the health of H's father, H and W are entitled to claim a reduced maximum exclusion under section 121(c)(2).
H and W purchase a house in 2003 that they use as their principal residence. Their son suffers from a chronic illness that requires regular medical care. Later that year their son begins a new treatment that is available at a hospital 100 miles away from their residence. In 2004 H and W sell their house so that they can be closer to the hospital to facilitate their son's treatment. Because, under the facts and circumstances, the primary reason for the sale is to facilitate the treatment of their son's chronic illness, H and W are entitled to claim a reduced maximum exclusion under section 121(c)(2).
B, who has chronic asthma, purchases a house in Minnesota in 2003 that he uses as his principal residence. B's doctor tells B that moving to a warm, dry climate would mitigate B's asthma symptoms. In 2004 B sells his house and moves to Arizona to relieve his asthma symptoms. The sale is within the safe harbor of paragraph (d)(2) of this section and B is entitled to claim a reduced maximum exclusion under section 121(c)(2).
In 2003 H and W purchase a house in Michigan that they use as their principal residence. H's doctor tells H that he should get more outdoor exercise, but H is not suffering from any disease that can be treated or mitigated by outdoor exercise. In 2004 H and W sell their house and move to Florida so that H can increase his general level of exercise by playing golf year-round. Because the sale of the house is merely beneficial to H's general health, the sale of the house is not by reason of H's health. H and W are not entitled to claim a reduced maximum exclusion under section 121(c)(2).
In 2003 A buys a house in California. After A begins to use the house as her principal residence, an earthquake causes damage to A's house. A sells the house in 2004. The sale is within the safe harbor of paragraph (e)(2)(ii) of this section and A is entitled to claim a reduced maximum exclusion under section 121(c)(2).
H works as a teacher and W works as a pilot. In 2003 H and W buy a house that they use as their principal residence. Later that year W is furloughed from her job for six months. H and W are unable to pay their mortgage and reasonable basic living expenses for their household during the period W is furloughed. H and W sell their house in 2004. The sale is within the safe harbor of paragraph (e)(2)(iii)(C) of this section and H and W are entitled to claim a reduced maximum exclusion under section 121(c)(2).
In 2003 H and W buy a two-bedroom condominium that they use as their principal residence. In 2004 W gives birth to twins and H and W sell their condominium and buy a four-bedroom house. The sale is within the safe harbor of paragraph (e)(2)(iii)(E) of this section, and H and W are entitled to claim a reduced maximum exclusion under section 121(c)(2).
In 2003 B buys a condominium in a high-rise building and uses it as his principal residence. B's monthly condominium fee is $X. Three months after B moves into the condominium, the condominium association replaces the building's roof and heating system. Six months later, B's monthly condominium fee doubles in order to pay for the repairs. B sells the condominium in 2004 because he is unable to afford the new condominium fee along with a monthly mortgage payment. The safe harbors of paragraph (e)(2) of this section do not apply. However, under the facts and circumstances, the primary reason for the sale, the doubling of the condominium fee, is an unforeseen circumstance because B could not reasonably have anticipated that the condominium fee would double at the time he purchased and occupied the property. Consequently, the sale of the condominium is by reason of unforeseen circumstances and B is entitled to claim a reduced maximum exclusion under section 121(c)(2).
In 2003 C buys a house that he uses as his principal residence. The property is located on a heavily traveled road. C sells the property in 2004 because C is disturbed by the traffic. The safe harbors of paragraph (e)(2) of this section do not apply. Under the facts and circumstances, the primary reason for the sale, the traffic, is not an unforeseen circumstance because C could reasonably have anticipated the traffic at the time he purchased and occupied the house. Consequently, the sale of the house is not by reason of unforeseen circumstances and C is not entitled to claim a reduced maximum exclusion under section 121(c)(2).
In 2003 D and her fiance E buy a house and live in it as their principal residence. In 2004 D and E cancel their wedding plans and E moves out of the house. Because D cannot afford to make the monthly mortgage payments alone, D and E sell the house in 2004. The safe harbors of paragraph (e)(2) of this section do not apply. However, under the facts and circumstances, the primary reason for the sale, the broken engagement, is an unforeseen circumstance because D and E could not reasonably have anticipated the broken engagement at the time they purchased and occupied the house. Consequently, the sale is by reason of unforeseen circumstances and D and E are each entitled to claim a reduced maximum exclusion under section 121(c)(2).
In 2003 F buys a small condominium that she uses as her principal residence. In 2005 F receives a promotion and a large increase in her salary. F sells the condominium in 2004 and purchases a house because she can now afford the house. The safe harbors of paragraph (e)(2) of this section do not apply. Under the facts and circumstances, the primary reason for the sale of the house, F's salary increase, is an improvement in F's financial circumstances. Under paragraph (e)(1) of this section, an improvement in financial circumstances, even if the result of unforeseen circumstances, does not qualify for the reduced maximum exclusion by reason of unforeseen circumstances under section 121(c)(2).
In April 2003 G buys a house that he uses as his principal residence. G sells his house in October 2004 because the house has greatly appreciated in value, mortgage rates have substantially decreased, and G can afford a bigger house. The safe harbors of paragraph (e)(2) of this section do not apply. Under the facts and circumstances, the primary reasons for the sale of the house, the changes in G's house value and in the mortgage rates, are an improvement in G's financial circumstances. Under paragraph (e)(1) of this section, an improvement in financial circumstances, even if the result of unforeseen circumstances, does not qualify for the reduced maximum exclusion by reason of unforeseen circumstances under section 121(c)(2).
H works as a police officer for City X. In 2003 H buys a condominium that he uses as his principal residence. In 2004 H is assigned to City X's K-9 unit and is required to care for the police service dog at his home. Because H's condominium association does not permit H to have a dog in his condominium, in 2004 he sells the condominium and buys a house. The safe harbors of paragraph (e)(2) of this section do not apply. However, under the facts and circumstances, the primary reason for the sale, H's assignment to the K-9 unit, is an unforeseen circumstance because H could not reasonably have anticipated his assignment to the K-9 unit at the time he purchased and occupied the condominium. Consequently, the sale of the condominium is by reason of unforeseen circumstances and H is entitled to claim a reduced maximum exclusion under section 121(c)(2).
In 2003, J buys a small house that she uses as her principal residence. After J wins the lottery, she sells the small house in 2004 and buys a bigger, more expensive house. The safe harbors of paragraph (e)(2) of this section do not apply. Under the facts and circumstances, the primary reason for the sale of the house, winning the lottery, is an improvement in J's financial circumstances. Under paragraph (e)(1) of this section, an improvement in financial circumstances, even if the result of unforeseen circumstances, does not qualify for the reduced maximum exclusion under section 121(c)(2).
Taxpayer A purchases a house that she uses as her principal residence. Twelve months after the purchase, A sells the house due to a change in place of her employment. A has not excluded gain under section 121 on a prior sale or exchange of property within the last 2 years. A is eligible to exclude up to $125,000 of the gain from the sale of her house (12/24 × $250,000).
(i) Taxpayer H owns a house that he has used as his principal residence since 1996. On January 15, 1999, H and W marry and W begins to use H's house as her principal residence. On January 15, 2000, H sells the house due to a change in W's place of employment. Neither H nor W has excluded gain under section 121 on a prior sale or exchange of property within the last 2 years.
(ii) Because H and W have not each used the house as their principal residence for at least 2 years during the 5-year period preceding its sale, the maximum dollar limitation amount that may be claimed by H and W will not be $500,000, but the sum of each spouse's limitation amount determined on a separate basis as if they had not been married. (See § 1.121-2(a)(3)(ii).)
(iii) H is eligible to exclude up to $250,000 of gain because he meets the requirements of section 121. W is not eligible to exclude the maximum dollar limitation amount. Instead, because the sale of the house is due to a change in place of employment, W is eligible to claim a reduced maximum exclusion of up to $125,000 of the gain (365/730 × $250,000). Therefore, H and W are eligible to exclude up to $375,000 of gain ($250,000 + $125,000) from the sale of the house.
