Most Massachusetts homeowners who've lived in their home for 2+ years owe nothing in capital gains. Here's how the federal exclusion and MA's 5% tax rate interact — by scenario.
The primary tax shelter for Massachusetts home sellers is the federal IRC § 121 exclusion. If you have owned the home and used it as your primary residence for at least 2 of the last 5 years before the sale, you can exclude:
The gain is calculated as: Sale Price − Adjusted Cost Basis. Adjusted cost basis includes your original purchase price plus eligible capital improvements (new roof, HVAC, additions, kitchen remodel) — not routine maintenance.
Massachusetts does not have a separate capital gains rate. All capital gains — short-term and long-term — are taxed as ordinary income at the flat rate of 5%. This applies to the portion of your gain that exceeds the federal IRC § 121 exclusion (if applicable), or to the full gain on investment properties and short-term sales.
| Scenario | Federal Tax | MA State Tax | Example |
|---|---|---|---|
| Primary residence — owned 2+ yrs, profit under exclusion | 0% — gain excluded under IRC § 121 | 0% — excluded gain not taxed | Bought at $200K, sold at $420K (single filer): $220K gain fully excluded |
| Primary residence — gain exceeds exclusion | 15% or 20% on gain above $250K/$500K exclusion (long-term) | 5% on gain above exclusion | Single filer with $320K gain: $250K excluded, $70K taxable. Federal ~$10,500, MA $3,500 |
| Investment property — held 1+ year | 15% or 20% long-term capital gains rate (no exclusion) | 5% on full gain (no exclusion) | Rental bought at $180K, sold at $300K: $120K gain taxable. Federal ~$18K, MA $6K |
| Short-term sale (owned < 1 year) | Ordinary income tax rates (22%–37% for most sellers) | 5% ordinary income rate | Flip bought at $200K, sold at $260K: $60K gain. Federal ~$13,200–$22,200, MA $3,000 |
| Inherited property sold | Stepped-up basis to fair market value at date of death — gain calculated from that date | 5% on gain above stepped-up basis | Inherited home worth $300K at death, sold at $320K: only $20K taxable |
| Partial IRC § 121 exclusion (relocation, job, health) | Pro-rated exclusion if didn't meet 2-year test; distance or health exception | 5% on taxable portion after partial exclusion | Lived in home 1 year, relocated for job — exclusion pro-rated to $125K/$250K |
