5 programs homeowners can claim

None of these are applied for you automatically. Each one is free to apply for. If you upload your bill, we check which ones are already on it and which may fit you.

Veterans exemptions (Clause 22 series)

Who
A Massachusetts veteran who lives in the home as their domicile on July 1. The veteran needs a service-connected disability of at least 10%, a Purple Heart, certain decorations, POW status, loss of a limb or sight, or a 100% disability, depending on the clause. Surviving spouses qualify under some clauses. Gold Star parents qualify under Clause 22. In a multi-unit building only your own unit counts.
What you get
Set amounts off your tax: Clause 22 $400, 22A $750, 22B $1,250, 22C $1,500, 22E $1,000. Or a set slice of assessed value if that gives you more. Clause 22D is a full exemption for surviving spouses of those killed in combat or who died of a service-connected injury, on stated conditions. Clause 22F is a full exemption, with a small amount left in some cases. Your town may also have accepted 22I (cost-of-living increase) or 22J (up to 100% more). The state reimburses part of the cost.
How to apply
Apply to your local board of assessors. Ask whether your town accepted 22I or 22J.
Deadline
You must live in the home as your domicile on July 1 of the fiscal year. The filing deadline is local.
After that
File as your assessors require.

Who
Your home is your domicile in a city or town that accepted MGL c. 59, s. 5C. It does nothing in towns that have not.

How to apply
Usually automatic based on your domicile. Some cities require an application.
Deadline
Set locally.

The percentage is voted each year. Acceptance continues until the town revokes it.

Senior Circuit Breaker tax credit (Schedule CB)

Who
Age 65 or older by December 31 of the tax year. You own or rent and live in a Massachusetts principal residence and are not a dependent. For tax year 2025, Massachusetts income can't be over $75,000 single, $94,000 head of household or $112,000 joint. Married filing separately does not qualify. The home's assessed value can't be over $1,298,000 as of January 1, 2025.
What you get
A refundable income tax credit of up to $2,820 for tax year 2025.
How to apply
File Schedule CB and Schedule HC with your Massachusetts income tax return.
Deadline
With your return for that tax year.
After that
Every year.

Schedule CB and Schedule HC: the form

Flat charges and parcel taxes. Where your town has adopted the Community Preservation Act surcharge, it has local exemptions for the first $100,000 of residential value and for certain low-income and senior owners. Ask your local assessors or town hall.
Think your value is too high?

Asking for a lower assessed value (full and fair cash value)

Free review
There is no statewide informal program. You can ask your assessors to review your value before you file an abatement.
Formal appeal
Your board of assessors, on an abatement application. After that, the Appellate Tax Board.
Deadline
The abatement application is due on or before the due date of the first installment of the actual tax bill, typically February 1.
Good to know
Check with your assessors on whether a review could raise your value. Keep paying your bill on time while your abatement is reviewed. You can prepare the abatement yourself.

A formal appeal reopens your whole value: the board can raise it as well as lower it. Bring recent sales of similar homes.

Source · We never charge for help asking for a lower value.

What can't come off

Charges you can't remove

Your bill can include the Community Preservation Act surcharge where your town adopted it, usually 1% to 3%. Water, sewer and betterments may be liens on the same bill, and they are not personal exemptions. Motor vehicle excise is a separate bill.
