Home Sale Exclusion Disputes Under Section 121: Snowbirds, Rentals, and Partial Exclusions

The home sale exclusion is the largest tax break most families ever use. IRC 121 lets you exclude up to $250,000 of gain on the sale of your principal residence, or up to $500,000 for married couples filing jointly who meet the requirements. For long-time Sarasota and Manatee homeowners, that can cover most or all of the gain.

Because the dollars are large, the IRS does test it. Disputes arise in predictable places: people with two homes, homes that were rented, sales before two years, and couples where only one spouse qualifies. Here is how each works.

The basic tests

IRC 121(a) requires that during the five years ending on the date of sale, you owned the property and used it as your principal residence for periods totaling at least two years. The two years do not have to be consecutive, and ownership and use do not have to overlap in time.

IRC 121(b) sets the limits:

• $250,000 generally.
• $500,000 for a joint return if either spouse meets the ownership test, both spouses meet the use test, and neither spouse used the exclusion on another sale in the prior two years.
• Once every two years. Under 121(b)(3), the exclusion generally does not apply if you excluded gain on another sale within the two years before this one.

Publication 523 walks through the computations and worksheets.

Snowbirds and second homes

Southwest Florida has many homeowners who split the year between a Florida home and one up north. Only one home can be your principal residence at a time. Treas. Reg. 1.121-1(b)(2) says that if you alternate between properties, the one you use a majority of the time during the year ordinarily is the principal residence. It lists other relevant factors, including:

• Your place of employment
• The principal place of abode of your family members
• The address on your federal and state tax returns, driver's license, vehicle registration, and voter registration
• Your mailing address for bills and correspondence
• The location of your banks
• The location of religious organizations and recreational clubs you belong to

Examiners request exactly those records. A Florida homestead exemption is helpful evidence of your intent, but it is a state property tax determination and does not by itself settle the federal question. If you plan to sell the northern home and claim the exclusion on it, you need to have lived there as your principal residence for two of the last five years, even if you now claim Florida as home.

Homes that were rentals

Two rules apply when a home was rented at some point.

Depreciation is never excluded

IRC 121(d)(6) says the exclusion does not apply to gain up to the amount of depreciation adjustments for periods after May 6, 1997. If you rented the home and claimed, or could have claimed, depreciation, that amount of gain is taxable, generally as unrecaptured section 1250 gain at up to 25 percent. See the recapture guide, which also explains why depreciation you never claimed still counts.

Nonqualified use

IRC 121(b)(5) reduces the exclusion for periods of nonqualified use after 2008. In general, that is time when the home was not your principal residence, such as when it was a rental or second home before you moved in. Gain is allocated to nonqualified use based on the ratio of nonqualified use to total ownership.

The statute carves out important exceptions. Time after the last date you used the home as your principal residence, within the five-year window, is not nonqualified use. So a homeowner who moves out and rents the home for up to three years before selling generally does not suffer a reduction for those rental years, though depreciation is still taxed. Certain periods of qualified official extended duty and temporary absences of up to two years for employment, health, or unforeseen circumstances are also excepted.

The common audit case: an investor converts a long-held rental into a residence, lives there two years, and claims the full exclusion. The nonqualified use rule allocates part of the gain to the rental years and taxes it.

Homes acquired in a 1031 exchange

IRC 121(d)(10) denies the exclusion if the home was acquired in a like-kind exchange and is sold within five years after acquisition. Converting exchange property into a residence is a five-year commitment at minimum. See the held for investment guide.

Selling before two years: the reduced exclusion

IRC 121(c) allows a reduced maximum exclusion if you fail the two-year tests, or the once-every-two-years rule, because the sale is by reason of a change in place of employment, health, or unforeseen circumstances. Treas. Reg. 1.121-3 provides the rules and safe harbors, such as a new job at least 50 miles farther from the home than the old one, a physician's recommendation for a change of residence for health reasons, and listed unforeseen events including death, divorce or legal separation, multiple births from the same pregnancy, and involuntary conversion of the home.

The reduced exclusion is a fraction of the full amount, based on the time you did meet the tests. A reduced exclusion of a $250,000 limit after one year of qualifying use can still be substantial.

Form 1099-S

Closing agents generally report real estate sales on Form 1099-S under IRC 6045(e). For a principal residence, a closing agent may skip reporting if the sale price is $250,000 or less ($500,000 for married sellers) and the seller provides written assurances that the gain is fully excludable. Otherwise, expect a 1099-S. If you receive one and your gain is fully excludable, you still generally report the sale on your return to show why no tax is due. A 1099-S with no matching entry on the return draws a notice.

Foreclosure and short sale of a home

Section 121 also applies to gain on a foreclosure, short sale, or deed in lieu, which are dispositions for tax purposes. The canceled debt piece is separate and is not covered by 121. See the deed in lieu guide.

What examiners ask for

1. Closing statements for the purchase and the sale
2. Proof of residence: driver's license, voter registration, utility bills, tax return addresses
3. Records of any rental periods, including Schedule E filings and depreciation schedules
4. Records of improvements that increase basis
5. For a reduced exclusion, documentation of the job change, medical recommendation, or unforeseen event

The exclusion is generous. It is also built on facts you can prove. Keep the proof with the house file, not in your memory.
