How Section 121 Exclusion Works
The Section 121 exclusion allows homeowners to exclude up to:

- $500,000 for married couples filing jointly
To qualify, you must have:
- Owned the home for at least 2 years
- Lived in the home as your primary residence for at least 2 years
- Not used the exclusion in the last 2 years
Why This Calculator Matters
Selling a home without understanding capital gains taxes can cost thousands. This tool helps you:
- Estimate taxable gains instantly
- Plan property sales strategically
- Reduce unexpected tax liability
Example Calculation
If you bought a home for $200,000 and sold it for $450,000:
- Total gain = $250,000
- If single → $250,000 excluded → $0 taxable
- If married → $500,000 excluded → $0 taxable
