Massachusetts Retirement Taxes (2026): 5% Rule & $2M Estate

2026 edition · statute-cited · part of Clear Money Guide’s 51-state retirement tax series. This guide covers state taxes on retirement income and estate transfers; property and sales taxes vary by county and are outside its scope.

Updated July 24, 2026. Quick answer: Massachusetts splits retirees into two tax classes. Exempt: Social Security, Massachusetts state/local contributory pensions, U.S. government pensions, military retirement, and pensions from states offering reciprocal treatment. Taxed at the flat 5%: private pensions, 401(k) and traditional IRA distributions — with basis from contributions Massachusetts already taxed recovered tax-free. Above roughly $1.1M of taxable income (2026, indexed) the 4% surtax kicks in — effectively a 5%/9% two-bracket system that large lump-sum withdrawals can stumble into. At death, the estate tax starts at an effective $2,000,000 — via credit mechanics most guides describe wrong.

How Massachusetts taxes retirement income (statute-cited)

Income tax	Flat 5%, plus a 4% surtax on taxable income over ~$1,107,750 (2026, indexed) — effectively 5%/9%
Social Security	Not taxed
MA state/local & U.S. government contributory pensions	Exempt (M.G.L. c. 62 §2(a)(2)(E)), incl. pensions from reciprocal states
Private pensions / 401(k) / IRA	Taxed at 5%; IRA/annuity basis from previously MA-taxed contributions is recovered tax-free — keep contribution records
Military retirement	Exempt (noncontributory U.S. pension)
Inheritance tax	None

Surtax planning note: the 9% band is per-year taxable income — a single large retirement-account lump sum or Roth conversion can cross it in a year where spreading the withdrawal would have stayed at 5%.

The estate tax: how the $2M threshold actually works

For deaths on/after January 1, 2023 (St. 2023, c. 50 — which doubled the old $1M threshold), Massachusetts grants a credit of $99,600, producing an effective exemption of $2,000,000; graduated rates run 0.8%–16%, and the threshold is not indexed. In a state where the median home carries substantial equity, a house plus retirement accounts plus life insurance crosses $2M more easily than most families expect — and there is no Massachusetts-specific portability, so couples still benefit from credit-shelter planning. Full table: estate tax by state.

Probate costs

Massachusetts follows the MUPC: reasonable compensation for personal representatives and counsel (M.G.L. c. 190B §3-719), no percentage schedule. Filing runs $390 for informal probate ($405 formal). Small estates: voluntary administration for personal property up to $25,000 (plus one motor vehicle, no solely-owned real estate), filed for just $115 after a 30-day wait (M.G.L. c. 190B §3-1201). Context: probate cost by state · small-estate limits by state · will vs. trust calculator.

Is Massachusetts a good state to retire in for taxes?

Depends entirely on your pension’s pedigree and your balance sheet: a retired Massachusetts teacher or federal employee living on an exempt pension plus Social Security pays essentially nothing; a private-sector retiree drawing the same income from a 401(k) pays a flat 5% on all of it. Either way, the estate tax is the state’s real bite — un-indexed at $2M in a high-home-equity state. New England retirees comparing New Hampshire or Florida should run the death-tax math, not just the income-tax math.

Massachusetts vs. common alternatives

State	Social Security	Pension / 401(k) / IRA	Estate tax	Inheritance tax
Massachusetts	Not taxed	Private pensions/401(k)/IRA taxed at 5%; gov pensions exempt	Yes — $2M via credit	None
Florida	Not taxed	Not taxed (no income tax)	None	None
Pennsylvania	Not taxed	Not taxed (retirement-age distributions)	None	Yes — 0/4.5/12/15% by heir class
Delaware	Not taxed	Exclude up to $12,500/person at 60+	None (repealed 2018)	None

What probate costs in Massachusetts

Massachusetts sets probate compensation by a “reasonable fee” standard with no percentage schedule, so anyone quoting a firm figure is estimating. And the small-estate shortcut of $25,000 does not clear a solely owned house on its own, which is the detail most guidance omits.
