Partial Home Sale Exclusion (2025)
If you sell your main home before meeting the 2-year test because of a work-related move (≥50 miles), a health reason, or an unforeseeable event, you can still claim a partial exclusion — prorated by (months you qualified ÷ 24) times the full $250,000 / $500,000 amount.

Important: This is a federal estimate only. It does not compute state capital-gains tax, and it does not model depreciation recapture (unrecaptured §1250 gain, taxed up to 25%) if the home was ever a rental.
