Questions about Home-Sale Capital-Gains Exclusion Quiz (Sec. 121)
Clear answers first. If one question changes the deal, bring it into the review before you move money.
Q1How much gain can the primary-residence exclusion shelter?+
Up to $250K single or $500K married filing jointly, if you qualify. After years of appreciation that can shelter a large chunk of your gain — but eligibility has specific tests, so confirm with your CPA before planning a sale around it.
Q2What's the core eligibility test?+
Owning and using the home as your primary residence for at least two of the last five years (both spouses must meet the use test for the full $500K). It's the gate most sales hinge on — verify your timeline against it.
Q3Can I use the exclusion more than once?+
Generally not within two years of a prior use — that can disqualify you. If you've excluded gain on another home recently, the timing matters, so check the last-two-years rule before counting on it again.
Q4Does renting the home ever reduce the exclusion?+
Yes. Non-qualified (rental) use can reduce the excludable amount, and depreciation taken during a rental period is recaptured. If the home was ever a rental, that's a flag for your CPA to size the real exclusion.
Q5What if my gain exceeds the exclusion?+
The excess is taxable capital gain, which is where planning matters — timing, basis from improvements, and coordination with other moves. On a large gain above the cap, the CPA conversation is about minimizing the taxable remainder.
Q6I'm sitting on a big gain — what's the move?+
Confirm the two-of-five-year test and any rental reduction with your CPA, then coordinate the sale timing to protect the gain. That coordination is part of a Real Estate Review.
