Property Taxes in Massachusetts: Rates, Due Dates, and Appeals

Property taxes in Massachusetts are set and collected by your city or town, not the state, and your bill depends on your home’s assessed value as of January 1, the local tax rate per $1,000 of value, and any exemptions you qualify for. The fiscal year runs July 1 through June 30, most communities bill quarterly, and late payments draw interest at 14 percent.¹²

How Your Bill Is Calculated

Every parcel in Massachusetts must be assessed at full and fair cash value, meaning the price a willing buyer and willing seller would agree on in an open-market transaction.³ The valuation date is January 1, so improvements you make after that date won’t appear on the tax rolls until the following fiscal year. Local Boards of Assessors handle the work, inspecting properties on a cycle and adjusting values to reflect recent sales.⁴

The tax rate itself comes from simple division. Municipal officials build a budget, subtract state aid and other non-property revenue, and the remainder is the levy. Divide the levy by the total assessed value of all taxable property in town, and you get the rate per $1,000. On a home assessed at $500,000 with a rate of $12 per thousand, the annual bill is $6,000 before any exemptions.

Not every community charges one rate across the board. Under the classification system, a city or town can adopt a residential factor that shifts a larger share of the levy onto commercial, industrial, and personal property.⁵ Boston, Worcester, and Springfield use split rates. Smaller towns more often apply a single rate to all property classes.

If your town has adopted the Community Preservation Act, a surcharge of up to 3 percent appears as a separate line on the bill, funding open space, affordable housing, historic preservation, and recreation. Over 200 Massachusetts municipalities participate. CPA communities typically exempt the first $100,000 of residential value and low-income residents from the surcharge.

Why Rates Change: Proposition 2½

Massachusetts caps how much total property tax revenue a community can collect through Proposition 2½. Two separate limits work together. The levy ceiling prevents any city or town from collecting more than 2.5 percent of the total fair cash value of all taxable property. The levy limit restricts the annual increase in total taxes to no more than 2.5 percent above the prior year’s maximum levy limit.⁶

Communities can add “new growth” on top of the 2.5 percent increase, capturing added value from new construction, major renovations, or property that becomes taxable for the first time. When a town needs more revenue than those limits allow, voters can approve an override, a debt exclusion, or a capital outlay expenditure exclusion.⁷ An override permanently raises the levy limit. A debt exclusion only lifts the limit temporarily, to pay off a specific borrowing such as a school construction bond, and the extra taxing authority ends when the debt is retired. All of these require a majority vote at the ballot box, which is why your tax rate can jump in a year when nothing about your own property has changed.

When Property Taxes Are Due

Most larger communities use quarterly billing, with payments due August 1, November 1, February 1, and May 1. If a due date falls on a weekend or holiday, it shifts to the next business day. The first two bills are preliminary, based on the prior year’s tax. The third and fourth bills reflect the current year’s assessed value and rate, which is when any increase from a reassessment or override typically shows up. Smaller municipalities may bill semi-annually instead.

Late payments trigger interest at 14 percent per year, calculated from the original due date.² If you pay within 30 days after a bill is first mailed, interest already accrued on that bill is waived, but that narrow window only matters when the municipality itself sent the bill late.

Tax Liens and Tax Takings

Unpaid taxes in Massachusetts can eventually cost you the house. If your taxes remain unpaid after the fourth-quarter due date, the municipality sends a demand notice requiring payment within 14 days. If you ignore it, the city or town can record an instrument of taking with the Registry of Deeds, placing a tax lien on the property. You typically have at least 12 months after that to pay the outstanding balance, interest, and costs. If you still don’t pay, the municipality can petition the Land Court to foreclose on your right to redeem. Once the Land Court issues a foreclosure decree, you lose ownership.

Exemptions That Reduce Your Bill

Massachusetts offers several statutory exemptions that reduce the tax you owe rather than your assessed value. The base statutory amounts are modest, but many communities have voted to double them, so check with your local assessor for the actual figure in your town. You must apply each year through the assessor’s office, and you can claim only one exemption per property per year, so if you qualify under more than one clause, pick the largest.

Seniors (Clause 41C): homeowners age 70 or older who meet income and asset limits. Base exemption is $500 off the bill or the tax on $500 of valuation, whichever reduces the bill more.⁸
Veterans (Clause 22): veterans with a service-connected disability rating of at least 10 percent, plus their spouses, surviving spouses, and Gold Star parents. Clauses 22A through 22F provide higher exemptions for more severe disabilities, Purple Heart recipients, and paraplegic or blind veterans.⁸
Blind persons (Clause 37): base exemption of $500 off the bill or the tax on $5,000 of valuation, whichever is greater.⁸
Surviving spouses (Clause 17D): base exemption of $175 off the bill or the tax on $2,000 of valuation, whichever is greater.⁸

Residential Exemption

Some municipalities also offer a residential exemption that shifts tax burden off owner-occupied homes and onto higher-value properties, investment properties, and non-owner-occupied apartments. The exemption subtracts a percentage of the average assessed residential value from every qualifying homeowner’s taxable valuation. If you own and live in the home, you benefit. If you own rental property or a second home, you pay more. Boston’s residential exemption is among the best known and produces significant savings for owner-occupants whose homes are valued below the local average. Not every community offers this, and the percentage varies.

The Senior Circuit Breaker Credit

The Circuit Breaker is a Massachusetts income tax credit, separate from the property tax exemptions above, that many eligible seniors miss. If you are 65 or older and your property taxes (or 25 percent of your rent) exceed 10 percent of your total Massachusetts income, you can claim a credit on your state return. For tax year 2025, the maximum credit is $2,820.⁹

Total Massachusetts income cannot exceed $75,000 for single filers, $94,000 for head of household, or $112,000 for married filing jointly. Your home’s assessed value must be $1,298,000 or less as of January 1 of the tax year.⁹ You claim it by filing Schedule CB with your state return. Renters qualify too, so this is one of the broader forms of tax relief available to older residents.

Challenging Your Assessment

If you believe the assessors have overvalued your property, file State Tax Form 128 with your local Board of Assessors.¹⁰ The application needs a clear description of the property and a specific explanation of why the value is too high. An independent appraisal or recent comparable sale data makes a real difference. Assessors reject a large share of abatement requests that arrive with nothing more than a general complaint about the bill.

The deadline is strict and cannot be extended. You must file by the due date of the first actual tax bill of the fiscal year. In quarterly-billing communities, that means February 1. Miss it by a day and you lose your right to challenge that year’s assessment.

If the assessors deny the abatement or fail to act within three months, you can appeal to the Massachusetts Appellate Tax Board. You have 60 days from the denial notice to file. Cases involving $25,000 or less in disputed tax can use a simplified small claims procedure. Larger disputes go through a formal hearing. File three copies of your petition and keep one stamped copy for your records.¹¹

Federal Deduction and Mortgage Escrow

You can deduct Massachusetts property taxes on your federal return if you itemize. For the 2026 tax year, the state and local tax deduction cap is $40,400 for most filers, covering the combined total of property taxes, state income taxes, and local taxes. For taxpayers with modified adjusted gross income above $500,000, the cap phases down but will not drop below $10,000. Itemizing only pays off if your total itemized deductions exceed the standard deduction, which for 2026 is $32,200 for married couples filing jointly, $16,100 for single filers, and $24,150 for heads of household.¹² A single homeowner whose only large itemizable expense is a $5,000 property tax bill will almost always do better with the standard deduction.

If you have a mortgage, your lender probably collects property taxes with your monthly payment and holds the money in escrow. Federal law caps the cushion your servicer may hold at one-sixth of estimated annual disbursements, roughly two months of escrow payments, and the servicer must perform an annual escrow analysis showing collections, payments, and any shortage or surplus.¹³ When your assessed value rises, expect your monthly mortgage payment to go up after the next analysis. If the servicer misses a tax payment, send a written notice of error right away. A missed payment can lead to a lien on your property even when the mistake was the servicer’s.¹⁴
