Senior Property Tax Exemption in Massachusetts: Clauses 17 and 41

A senior property tax exemption in Massachusetts is a direct reduction to your local property tax bill, granted by your town’s Board of Assessors if you meet age, residency, ownership, income, and asset requirements. The state sets the framework through Chapter 59 of the General Laws, but each city and town chooses which exemption clauses to adopt and can adjust the qualifying limits upward from the statutory base. That means the answer to “do I qualify” almost always depends on which clause your specific municipality uses and what its current thresholds are.

Beyond the local exemption, Massachusetts also runs a state income tax credit called the Circuit Breaker, a tax deferral program, and an optional volunteer work-off program. Many seniors qualify for one of these even when the local exemption is out of reach.

Who Qualifies: The Common Requirements

Every senior exemption shares a few rules. Age, ownership, and other qualifying factors are measured as of July 1 of the tax year.¹ You must own the property and live in it as your primary home on that date. Ownership can be individual, joint with a spouse, tenancy in common, or a life estate. If your home is held in trust, you generally qualify only if you are a trustee or co-trustee with a sufficient beneficial interest.

Most clauses require ten consecutive years of Massachusetts domicile and five years of owning and occupying either this home or another Massachusetts property. A surviving spouse who inherited the home and has lived there for five years can also qualify. These periods are measured backward from July 1.

You can only claim one exemption per property per year. If you fit more than one clause, pick the one that saves you the most.²

Clause 17: Age 70 With Modest Assets, No Income Test

The Clause 17 family is aimed at homeowners age 70 and older whose overall wealth is limited but whose income may be higher than other programs allow. Under the base Clause 17, the exemption equals $175 or the tax on $2,000 of taxable valuation, whichever produces the larger reduction. Your total estate, not counting your home and certain other exempt property, cannot exceed $20,000.¹ There is no income test.

Clause 17C mirrors the base clause with the same $175 exemption, an age-70 requirement, and ten years of ownership and occupancy. Clause 17D, the version most towns have adopted today, lets the municipality raise the asset ceiling to reflect local property values. If your income disqualifies you from the Clause 41 programs below but your savings and investments are limited, a Clause 17 variant may be the right fit.

Clause 41: Larger Exemptions With Income and Asset Limits

The Clause 41 family provides bigger reductions but tests both income and assets. Most Massachusetts towns have adopted at least one version.

Clause 41B

Clause 41B offers $500 or the tax on $4,000 of taxable valuation, whichever is larger. You must be 70 or older, domiciled in Massachusetts for ten years, and have owned and occupied a home in the state for five years. The statutory income ceiling is $10,000 single, $12,000 married; the asset ceiling is $20,000 single, $23,000 married, excluding your home.¹

Those income numbers look impossibly low on paper, but the statute lets you subtract an amount equal to the minimum Social Security payment for a retired worker age 70 or older (or for a worker and spouse if married). The Commissioner of Revenue sets that deduction annually, and it effectively raises the real income ceiling well above the statutory figure. Ordinary business expenses and losses also reduce countable income; personal and family expenses do not.

Clause 41C

Clause 41C uses the same exemption amount as 41B but starts with higher limits: $13,000 single or $15,000 married on income, and $28,000 single or $30,000 married on assets.¹ The same Social Security deduction applies. Towns that adopt 41C can vote to lower the age below 70, raise the income and asset ceilings, and increase the exemption amount. This is where most of the real-world variation between towns comes from.

Clause 41C½

Clause 41C½ takes a percentage approach. The exemption starts at 5 percent of the average assessed value of all residential (Class 1) parcels in your city or town, and a municipality can vote to raise that to 20 percent. In higher-value communities, this can produce a much larger benefit than the flat $500 under 41C.¹

The income limit under 41C½ is tied to the Circuit Breaker credit threshold and adjusts annually for cost of living. For tax year 2025, a single non-head-of-household filer cannot exceed $75,000 in total income.³ Towns can also drop the qualifying age to 65 and shorten the residency requirement to five years.

How Income and Assets Are Counted

The definitions are broader than most people expect. “Gross receipts” includes Social Security, pensions, annuities, interest, dividends, IRA distributions, and other income before deductions. The main offset is the Social Security deduction, which the Commissioner of Revenue recalculates each year and which applies to Clause 41B, 41C, and related provisions.

The “whole estate” calculation captures bank accounts, stocks, bonds, IRAs, annuities, and any real estate beyond your home. Your primary residence is excluded as long as it does not exceed a certain number of dwelling units or produce rental income. Cemetery plots, registered motor vehicles, clothing, and household furnishings inside your home are excluded. If you co-own your home with someone other than your spouse, your exemption is prorated by your ownership share.

Municipalities can raise these limits well above the statutory base, and two towns ten miles apart can have very different qualifying thresholds. Your assessor’s office publishes the current numbers for your community each fiscal year, and that office is the only reliable source for the figures that will actually apply to your application.

The Senior Circuit Breaker Credit

Separate from the local exemption, Massachusetts offers a refundable state income tax credit that returns a portion of your property taxes when they consume a disproportionate share of your income. For tax year 2025, the maximum credit is $2,820.⁴ Because the credit is refundable, you receive the full amount even if it exceeds the income tax you owe.

To qualify, you must be 65 or older by December 31 of the tax year and own or rent a Massachusetts home as your primary residence. Income cannot exceed $75,000 single, $94,000 head of household, or $112,000 married filing jointly. For homeowners, your property tax plus half your water and sewer charges must exceed 10 percent of total income. For renters, 25 percent of annual rent must exceed that same threshold.³ Homeowners also face an assessed-value cap of $1,298,000 for tax year 2025.

You claim the credit by filing Schedule CB with your Massachusetts income tax return. It goes through the Department of Revenue rather than your assessor. You can receive both a local exemption and the Circuit Breaker, though the exemption amount reduces the property taxes counted toward the Circuit Breaker calculation. Many seniors who are turned down at the assessor’s office because their income is too high still qualify for the Circuit Breaker, so run the numbers even after a local denial.

Deferral: Postponing the Tax Rather Than Reducing It

If you don’t qualify for an exemption or need more substantial relief, Clause 41A lets seniors defer property tax payments until the home is sold or transferred. This is not forgiveness. It is a loan secured by a lien on your property that lets you stay in the home without paying the annual tax out of pocket.⁵

You must be 65 or older on July 1, domiciled in Massachusetts for ten years, and have owned and occupied the property for five years. The base income limit is $20,000 in gross receipts (including a spouse’s income), though your town can adopt a higher limit tied to the Circuit Breaker threshold. Interest accrues at 8 percent per year unless the town has voted a lower rate.¹

When you sell or transfer the property, all deferred taxes plus accumulated interest are due. The assessors record a lien at the registry of deeds when the agreement is signed. Reverse mortgage liens take priority over the deferral lien. Deferral makes sense when your home equity is substantial but cash flow is tight, though 8 percent interest is expensive over a long period. Ask whether your town has adopted a lower rate before signing.

Senior Tax Work-Off

Under Chapter 59, Section 5K, cities and towns can let residents age 60 and older volunteer their services in exchange for a property tax reduction of up to $2,000 per year.⁶ Volunteers are credited at the state minimum wage per hour, and the reduction stacks on top of any exemption or abatement you already receive. Towns can also allow an approved representative to perform the work for seniors who are physically unable, or cap participation at 125 service hours per year. Not every town has adopted the program, so ask your local selectmen’s or town manager’s office.

How to Apply

The standard form is State Tax Form 96-1, “Application for Statutory Exemption,” available from your Board of Assessors or on the Department of Revenue website.⁷ It asks about ownership, income, and assets. Call your assessor’s office first to confirm which clause your town has adopted, what its current limits are, and whether any local forms accompany the state form.

Bring supporting documents:

Proof of age, such as a birth certificate or Massachusetts driver’s license, usually only in your first year applying.
Income records: federal and state tax returns, Social Security statements, pension statements, and records of interest, dividends, and annuity payments for the preceding calendar year.
Asset records: bank statements, investment account statements, and records of any real estate beyond your primary home, valued as of July 1.

The filing deadline is April 1, or three months after the actual (not preliminary) tax bills for the fiscal year are mailed, whichever is later.⁷ Assessors have no authority to waive or extend this deadline. Filing does not pause tax collection, so keep paying your bills; if the exemption is approved, you receive a refund for any overpayment. You must reapply every fiscal year.

After You File

The Board of Assessors has three calendar months to act on your application. You can agree in writing to extend that period, but without such an agreement, if the board hasn’t responded within three months, the application is automatically deemed denied.⁷ Approved exemptions are applied to your tax bill and reduce the amount still owed for the fiscal year.

If denied, you can appeal to the Massachusetts Appellate Tax Board within three months of the denial date. To preserve your right to a hearing, you generally must have paid all of the real property tax for the fiscal year without incurring interest on any installment, with limited exceptions for taxes under $3,000.⁸ The assessors may also reach a settlement during the appeal window, so a local denial is not always the last word.
