Massachusetts · Tax year 2026
What will you owe in capital gains tax when you sell your Massachusetts home?
Estimate federal and Massachusetts tax on the sale of a primary residence, rental, or second home. Built for North Shore sellers by Armstrong Field Group, with the home sale exclusion, improvements, selling costs, depreciation recapture, and the Massachusetts 4% surtax all included.
How is the gain on a Massachusetts home sale taxed?
Your gain is the sale price minus selling costs, minus your adjusted basis: what you paid, plus purchase closing costs and capital improvements. If the home was your main residence for at least 2 of the last 5 years, you can exclude up to $250,000 of gain ($500,000 for most married couples filing jointly). Massachusetts follows the same exclusion, so excluded gain is tax-free at both levels.
What rates apply in 2026?
Federally, long-term gains are taxed at 0%, 15%, or 20% depending on your taxable income, plus a 3.8% net investment income tax for higher earners. Massachusetts taxes long-term gains at 5% and gains on property held a year or less at 8.5%. Taxable income above $1,107,750 also pays the state's 4% surtax, and a large home sale can push you over that line in a single year.
Why do improvement records matter so much?
Every dollar of documented capital improvements reduces your taxable gain. For long-time owners in Beverly, Marblehead, Swampscott, or Manchester-by-the-Sea, appreciation can easily exceed the $500,000 exclusion. A kitchen, an addition, or a new roof from years ago can save thousands, but only if you can document it.
What about rental and investment property?
The home sale exclusion doesn't apply. Depreciation you claimed (or could have claimed) is taxed federally at up to 25%, and the rest of the gain at capital gains rates. Many investors defer the tax with a 1031 exchange into another investment property. Talk with your CPA and a qualified intermediary before you list.

An estimate, not tax or legal advice. This calculator assumes a full-year Massachusetts resident and uses 2026 federal brackets and standard deductions. It does not model the alternative minimum tax, the additional senior standard deduction or senior deduction, Massachusetts personal exemptions and adjustments, nonqualified use periods, installment sales, 1031 exchanges, or capital losses from other investments. Married couples are assumed to both meet the use test for the $500,000 exclusion.
