Property Tax Breaks for Seniors in Massachusetts (2026)

Updated August 12, 2026. Quick answer: Massachusetts runs three different things, and the one worth the most to most seniors is not a property-tax break at all — it is a refundable circuit-breaker credit on your state income tax return. The two programmes that do touch the tax bill, the Clause 41C exemption and the Clause 41A deferral, are local options: the statewide statute sets a floor so low that in a town which has not voted to raise it, almost no one qualifies.

What Massachusetts offers

• Senior Circuit Breaker credit — age 65 or older, on the home you own or rent as your principal residence. The credit is the amount by which your property tax — or 25% of your rent — exceeds 10% of your total income, and it is refundable. The statute sets the caps at a $1,500 credit, income of $40,000 single / $50,000 head of household / $60,000 filing jointly, and an assessed valuation of $600,000; every one of those is adjusted for inflation each year (the income and credit limits from a 1999 base, the valuation limit from a 2004 base by a cost-of-housing adjustment), so the figures actually in force are well above the statutory ones. It is a large programme: the Governor’s FY2027 budget scores it at $186.6 million for FY2026 and $192.7 million for FY2027.
• Clause 41C exemption — age 70 or older — a city or town may vote that down to 65 — domiciled in Massachusetts for the preceding 10 years, having owned and occupied property in the state for 5 years, with prior-year gross receipts under $13,000 single or $15,000 married, and a whole estate excluding the home of no more than $28,000 or $30,000. It exempts $4,000 of taxable valuation or $500 of tax, whichever gives the greater relief. A city or town may double the exemption, raise the income limits to $20,000 / $30,000 and the asset limits to $40,000 / $55,000.
• Clause 41C½ — the larger local-option exemption: 5% of the average assessed value of all Class-one parcels in the city or town, which the town may raise to as much as 20%. Same 70-or-older rule (lowerable to 65) and the same residency tests, with income measured against the circuit-breaker limit for a single filer.
• Clause 41A deferral — age 65 or older, domiciled in Massachusetts 10 years, owning and occupying for 5, with gross receipts of no more than $20,000 — a town may raise that to the circuit-breaker single-filer income limit. Interest runs at 8% a year unless the town votes a lower rate. Deferred taxes plus interest may never exceed 50% of your share of the home’s full and fair cash value. The agreement is recorded at the registry of deeds and operates as a lien, and any joint owner or mortgage holder has to approve it in writing first. Heirs can clear it by paying in full; a surviving spouse who signs a deferral agreement is not required to pay during their life.

The catch most senior-exemption roundups skip

Every number in Clause 41C is a local option, and the statewide default is close to unusable. On the statute’s own floor you need gross receipts under $13,000 and a whole estate under $28,000 to collect $500. What your town has voted — the age, the income limits, the asset limits, whether it doubled the exemption, whether it adopted Clause 41C½ at all — is the entire question. Ask your assessor what the town has adopted, not what the state allows.

And the circuit breaker does not lower your tax bill. It arrives as a refund on your Massachusetts income tax return, which means you have to file a state return to get it even if your income is low enough that you would not otherwise have to file one. That is the single most common reason it goes unclaimed.

How to apply

The exemption and the deferral go to your local board of assessors; the deadline is the town’s application deadline for the fiscal year. The circuit-breaker credit is claimed on your Massachusetts personal income tax return (Schedule CB).

Honest gap. The current year’s indexed figures for the circuit breaker — the actual maximum credit, income limits and valuation cap in force — are announced each year by the Department of Revenue in a Technical Information Release, and we could not reach that release from its source when this page was written. Rather than publish a number we did not read, we give the statutory base above and the indexing rule that moves it. Get the current figure from the Department of Revenue’s current-year release or from your assessor.

Two things to check before you count on it

• Thresholds move. Age and income limits are reset by legislatures and are frequently indexed. Every figure above carries the year we confirmed it; confirm the current one before you budget around it.
• Your county or town may add its own. Statewide programmes are the floor. Counties and municipalities frequently run additional exemptions, and those are where a lot of real money sits.

Disabled Veteran Property Tax Relief in Massachusetts: Greater of $2,000 Assessed Value or $400 Tax Abatement

Mass. Gen. Laws ch. 59, § 5, cl. Twenty-second is the primary authority for this state-specific rule.

• Massachusetts ties this veteran clause to state residence, discharge, and domicile or two-year residence conditions.
• The cited clause uses the greater tax abatement produced by $2,000 of assessed taxable valuation or $400.
• When both spouses are qualifying veterans, each receives the clause's exemption amount as if unmarried.

Before applying, match the rating letter, ownership, occupancy, survivor status, and filing timing in your records to the controlling text; confirm current filing instructions with the administering agency.
