The IRS Section 121 Exclusion lets you exclude up to $250,000 (single) or $500,000 (married filing jointly) of profit from selling your main home, provided you've owned and lived in it as your primary residence for at least two of the five years before the sale. This tax break isn't a once-in-a-lifetime deal, but you generally can't claim it again for two years. Special rules allow for partial exclusions due to health, job changes, or military service, and you must also account for any depreciation claimed on the home.

In order to claim the exclusion, the homeowner(s) has to have owned the home in question and used it as a primary residence for at least two out of the five previous years. While the 5-year period ends on the date the house is sold, the 2 years do not have to be consecutive.
