Property taxes are an important part of owning real estate in Massachusetts, but what happens if you believe your property has been assessed incorrectly? Depending on the circumstances, you may be able to request a property tax abatement.
A tax abatement can reduce the property tax owed when a local assessment does not accurately reflect a property's value, classification, or proportional share of taxes. Because Massachusetts municipalities establish property assessments and administer local property taxes, the process and exact dates can vary depending on where your property is located.
Here's what Massachusetts property owners should know about property tax abatements, including how the process works and the deadlines to keep in mind.
What Is a Property Tax Abatement in Massachusetts?
A property tax abatement is a reduction in the tax assessed on a property. Massachusetts law allows an eligible taxpayer to apply for an abatement when they believe a property has been taxed at more than its fair share, improperly classified, or assessed above its fair cash value.
Importantly, an abatement isn't simply a request to lower a tax bill because the amount has increased. It challenges the underlying assessment or treatment of the property.
Property tax abatements are handled locally. Applications are submitted to the board of assessors in the city or town where the property is located, rather than to the Massachusetts Department of Revenue.
When Can You Request a Property Tax Abatement?
There are several circumstances that may provide grounds for requesting an abatement. For example, a property owner might question an assessment because:
The assessed value appears to exceed the property's fair cash value.
The property was improperly classified.
The assessment is disproportionate compared with other properties.
Information used to assess the property is inaccurate.
Before filing, it can be useful to review your property record and assessment information. Details such as square footage, lot size, property type, condition, and other characteristics can affect how a property is valued.
An increase in assessed value by itself does not necessarily mean an assessment is incorrect. Assessments can change as market conditions and property characteristics change.
How to Apply for a Property Tax Abatement in Massachusetts
Property owners generally begin by obtaining the approved abatement application from their local assessor's office. Massachusetts provides a standard application, but owners should check directly with their municipality for its filing procedures and requirements.
Supporting information can play an important role in an abatement request. Depending on the circumstances, this could include property records, documentation of factual errors, photographs, or information about comparable properties.
The assessors review the application and determine whether an adjustment is warranted.
Filing an application does not automatically suspend the obligation to pay the property tax bill. Massachusetts guidance advises taxpayers to continue paying taxes as assessed while the application is pending to avoid interest, collection issues, or potentially affecting appeal rights.
Massachusetts Property Tax Abatement Deadlines
Deadlines are especially important because local assessors generally cannot extend or waive the statutory filing deadline.
Under Massachusetts law, an abatement application generally must be filed by the due date of the first installment of the actual tax bill issued after the municipality establishes its tax rate.
In communities using quarterly billing, that date is commonly February 1, although circumstances such as a later mailing date can affect the deadline. Semiannual billing communities follow a different schedule.
Always confirm the deadline printed on your tax bill and with your local assessor rather than assuming a particular date applies.
Boston Property Tax Abatements
Boston provides a useful example of how the process works locally.
For Fiscal Year 2027, Boston property owners may file an abatement if they believe their property is overvalued, disproportionately assessed, improperly classified, or eligible for a statutory exemption. Applications become available after third-quarter bills are issued, and the FY2027 deadline is February 1, 2027.
Boston's Assessing Department has three months to review an abatement application and respond.
Tax Abatement vs. Tax Exemption: What's the Difference?
Although the terms are sometimes confused, a property tax abatement and property tax exemption are not the same thing.
An abatement generally challenges the assessment or taxation of a property for a particular fiscal year.
An exemption reduces the taxable value or tax obligation when a property or owner meets specific eligibility requirements established by law or a local program.
For example, Boston offers a residential exemption for qualifying homeowners who occupy a property as their principal residence. The residential exemption reduces the tax bill by excluding a portion of the property's value from taxation.
The filing deadlines can also differ. For Boston Fiscal Year 2027, the real estate tax abatement deadline is February 1, 2027, while the residential exemption application deadline is April 1, 2027.
Property owners should confirm which program applies to their circumstances before filing.
What Happens if a Property Tax Abatement Is Denied?
A denial from the local assessor does not necessarily end the process. Depending on the circumstances and whether applicable requirements have been met, a taxpayer may have the right to appeal to the Massachusetts Appellate Tax Board.
Appeal deadlines are separate from the initial abatement deadline and can be strict. Property owners considering an appeal should review the Massachusetts Appellate Tax Board requirements promptly after receiving a decision.
Why Property Taxes Matter When Buying Massachusetts Real Estate
Property taxes can represent a significant ongoing ownership expense, particularly when comparing homes across different Massachusetts cities and towns.
Before purchasing a property, buyers should review the current assessed value, recent tax bills, applicable municipal tax rate, and available exemption programs. It's also important to remember that the current owner's tax bill may not necessarily reflect what a new owner will pay.
Understanding these details early can provide a clearer picture of the ongoing costs associated with a property.
