Massachusetts taxes for early retirees: a flat 5% with a few sharp corners

By Tom, CPA · Updated October 28, 2026

TL;DR: Massachusetts taxes most income, including IRA withdrawals and long-term gains, at a flat 5%, exempts Social Security and many government pensions, and taxes short-term gains at 8.5%. Traditional IRA contributions were never deductible in Massachusetts, so they can come back out tax-free. Income above $1,107,750 in 2026 pays an extra 4%, and estates above $2 million can owe estate tax.

Massachusetts has a flat income tax, which sounds refreshingly simple, like a tax system designed by someone who owns exactly one sweater. Most income is taxed at 5%. Social Security is exempt. There's no bracket creep, no phase-out cliff and no age test for your IRA withdrawals. Five percent of the next dollar is five percent of the next dollar.

But "flat" doesn't mean "plain." Massachusetts taxes short-term capital gains at 8.5%. It adds a 4% surtax on income above $1,107,750 for 2026, which turns a once-in-a-lifetime business or property sale into a once-in-a-lifetime surtax bill. It doesn't let you deduct traditional IRA contributions, which means some of your IRA may already have been taxed. And it has an estate tax that starts at $2 million, a level a paid-off house in the Boston suburbs and a decent 401(k) can reach together. This guide covers the rules as of October 2026 and how an early retiree can plan around them.

CPA Warning Label: Massachusetts never let you deduct your IRA contributions. Without your old records, you can end up paying state tax on the same money twice.

The rates: 5% on almost everything, with three exceptions

Per the DOR tax rates page and the 2026 Form 1-ES:

The sales tax rate is 6.25%. Unlike the federal system, there's no 0% bracket for long-term gains. A couple who harvests gains in the federal 0% bracket (see the 0% capital gains harvesting guide) still pays Massachusetts 5% on them. And unlike the federal system, there's no standard deduction; Massachusetts uses personal exemptions instead.

Exemptions: what you subtract before the 5%

The personal exemption is $4,400 for single filers and married filing separately, $6,800 for head of household, and $8,800 for married filing jointly. On top of that:

• $700 for each person 65 or older by December 31 of the tax year (note: December 31, not the federal January 1 rule).
• $2,200 for each person who is legally blind.
• $1,000 per dependent.
• Medical and dental expenses, but only if you itemize on your federal return. The Massachusetts amount equals what you claimed on federal Schedule A, line 4.

The old deduction for interest from Massachusetts banks was repealed for tax years beginning in 2024. Very low-income households get relief through No Tax Status (Massachusetts AGI of $8,000 or less single, or $16,400 plus $1,000 per dependent for joint filers) and the Limited Income Credit (up to $14,000 single, or $28,700 plus $1,750 per dependent joint). Those are the amounts on the DOR page as of October 2026, and married filing separately doesn't qualify for either.

What's exempt: Social Security, many government pensions, military pay

Social Security isn't included in Massachusetts gross income at all, and neither are Tier I and Tier II Railroad Retirement benefits. U.S. military pensions are excluded too.

Government pensions get special treatment because employees contributed after-tax money in Massachusetts. Distributions from Massachusetts state and local contributory pensions (including police and fire), and from federal contributory pensions such as U.S. Postal Service pensions, are excluded from Massachusetts gross income even though they're federally taxable. Not every government plan qualifies: the federal Thrift Savings Plan and 457 deferred compensation plans are taxable when you take the money out.

If you move to Massachusetts with a contributory public pension from another state, you can deduct it if that state gives a matching break to Massachusetts public pensions or has no income tax. Private pensions, 401(k)s and 403(b)s are a different story; they're generally taxable.

The IRA basis rule: Massachusetts may have already taxed your IRA

Here's the quirk that can save real money. Massachusetts doesn't allow a deduction for traditional IRA contributions (or Roth contributions, or Keogh contributions). If you contributed to a deductible traditional IRA while you lived in Massachusetts, you deducted it on your federal return but paid Massachusetts tax on it. Those dollars are your Massachusetts previously taxed contributions.

When you take a distribution, or convert to a Roth, Massachusetts taxes it only to the extent it exceeds those previously taxed contributions. You figure it on the worksheet for Schedule X, line 2. If you spent 20 years maxing out an IRA as a Massachusetts resident, a large slice of your early withdrawals or conversions may be tax-free in Massachusetts.

Two caveats from the DOR pages. First, if you moved to Massachusetts from another state, you get no adjustment for contributions made while you lived elsewhere. Second, 401(k), 403(b), 457, SEP and SIMPLE deferrals follow federal treatment, so they weren't taxed going in and they're fully taxable coming out. An IRA built from a 401(k) rollover usually has no Massachusetts basis. Dig out your old Form 5498s before you assume either way.

Qualified Roth distributions are excluded, and qualified charitable distributions from an IRA (age 70½ and up, up to $100,000) are excluded as well.

Illustration: flat really is flat

Meet Robin and Lee, both 66, married filing jointly. They have $40,000 of Social Security, $60,000 of traditional IRA withdrawals from a 401(k) rollover (no Massachusetts basis), $5,000 of interest and dividends, and $10,000 of long-term capital gains.

Now they add a $20,000 Roth conversion. Massachusetts tax goes up by exactly $1,000, to $4,240. No cliffs, no phase-outs. If that $10,000 of gains had been short-term instead, they'd pay 8.5% on it, adding $350.

Now suppose Lee had $30,000 of Massachusetts previously taxed IRA contributions. A $20,000 conversion out of that IRA could come out entirely free of Massachusetts tax, saving the $1,000. The federal tax is the same either way; the state savings come from a shoebox of old paperwork.

For a 55-year-old couple living on $70,000 of IRA withdrawals, the math is $70,000 minus the $8,800 exemption, times 5%, or $3,060. There's no age 62 or 65 threshold for retirement income like New Jersey or Virginia have; a 55-year-old and an 85-year-old are taxed the same way except for the $700 age exemption.

The 4% surtax: the one-year problem

Since 2023, Massachusetts residents pay an extra 4% on taxable income above a threshold that's indexed each year: $1,053,750 for 2024, $1,083,150 for 2025, and $1,107,750 for 2026. The surtax applies to all taxable income combined, including capital gains, so a retiree who normally lives on $90,000 can hit it in the year they sell a business or a rental property.

Example: a single filer with $1,307,750 of taxable income in 2026 is $200,000 over the threshold and owes a $8,000 surtax on top of the regular tax. Spreading a large gain over several years with an installment sale, or bunching it into a year with little other income, can reduce or avoid the surtax. Anyone who owes the surtax must file and pay electronically.

Senior Circuit Breaker credit: up to $2,820 back

Homeowners and renters age 65 or older can claim a refundable credit based on property taxes or rent. For tax year 2025 (TIR 25-7):

• Maximum credit: $2,820.
• Total income limits: $75,000 single, $94,000 head of household, $112,000 married filing jointly.
• Homeowners: the home's assessed value can't exceed $1,298,000. The credit is property tax (including water and sewer charges) above 10% of total income.
• Renters: the credit is 25% of rent paid above 10% of total income.

Example: a 67-year-old single homeowner with $40,000 of total income and $6,500 of property tax and water and sewer charges gets $6,500 minus $4,000, or a $2,500 credit, even if she owes no income tax. "Total income" for this credit is defined in the credit's own rules, so check the Schedule CB instructions rather than assuming it matches taxable income.

Not yet published: as of October 28, 2026, DOR hasn't released the TIR with the 2026 circuit breaker amounts. The thresholds are indexed every year, so expect them to change.

Estate tax: starts above $2 million, but no cliff

Massachusetts requires an estate tax return when the gross estate plus adjusted taxable gifts exceeds $2,000,000 for deaths on or after January 1, 2023. The tax is calculated using the old federal credit for state death taxes, with rates from 0.8% to 16%, and then reduced by a $99,600 credit. That credit wipes out the tax for a taxable estate of about $2 million, so there's no longer a cliff that taxes the whole estate the moment you cross the line.

Example: a Massachusetts resident with a $3,000,000 taxable estate (no out-of-state real estate). The adjusted taxable estate is $3,000,000 minus $60,000, or $2,940,000. Table B gives $146,800 plus 8.8% of the excess over $2,540,000, or $182,000. Subtract the $99,600 credit and the Massachusetts estate tax is $82,400, while the 2026 federal basic exclusion amount is $15,000,000, so there's no federal estate tax at that size. Life insurance and retirement accounts count toward the gross estate. More on the federal side in our estate tax basics guide.

Health insurance mandate: early retirees, take note

Massachusetts has its own individual mandate, separate from federal law. Adults 18 and older who can afford coverage must have health insurance that meets the state's minimum creditable coverage standards, or they pay a penalty on their income tax return. For 2026 (TIR 26-1), there's no penalty at or below 150% of the federal poverty level, the penalty for income above 400% of the poverty level is $211 a month ($2,532 for a full year) per adult, and a lapse of 63 days or less doesn't trigger a penalty.

For a 55-year-old retiree, coverage is a planning item anyway. See health insurance before Medicare and the ACA subsidy cliff guide.

Estimated payments and residency

You generally need estimated payments if you expect to owe more than $400 of tax on income without withholding. The 2026 due dates are April 15, June 15 and September 15, 2026, and January 15, 2027. IRA withdrawals and conversions are a common source of underpayment for new retirees.

You're a Massachusetts resident if it's your domicile, or if you maintain a permanent place of abode in the state and spend more than 183 days there during the year, even if you're domiciled somewhere else. Snowbirds keeping a Cape house should count days carefully; see the residency change guide.

A Massachusetts early-retirement checklist

• Find your records of traditional IRA contributions made while living in Massachusetts. Those are previously taxed contributions.
• Hold investments more than a year before selling; short-term gains are taxed at 8.5%.
• If a big sale is coming, check it against the 4% surtax threshold and consider spreading it out.
• At 65, claim the $700 exemption and check whether you qualify for the circuit breaker credit.
• Keep health coverage that meets state standards.
• If your estate could exceed $2 million, review it with the $99,600 credit in mind.
• Make estimated payments if you'll owe more than $400.
