When Do Property Tax Bills Come Out in Massachusetts? Key Dates and Deadlines
TL;DR
Massachusetts tax bills arrive in December-January with assessed values included. The deadline to apply for an abatement with the local board of assessors is February 1 (or 30 days after the third quarter bill, whichever is later). If denied, you can appeal to the Appellate Tax Board. Massachusetts reassesses annually. Tax bills are due quarterly in most communities: August 1, November 1, February 1, and May 1. The February 1 deadline is critical. Miss it and you wait another year.

Massachusetts Assessment System
Massachusetts reassesses all property annually. The Board of Assessors in each municipality determines values based on market data, and the state Department of Revenue certifies the assessments.
Massachusetts assesses at 100% of fair cash value. The assessed value on your tax bill should represent what the assessor believes your home would sell for on the open market as of January 1.
Understanding this topic fully means looking at both the big picture and the specific details that apply to your situation. Every property is different, and the strategies that save the most money are the ones tailored to your particular home, location, and circumstances.
Start by gathering the basic facts about your property: its assessed value, the tax rate in your jurisdiction, and any exemptions currently applied. Then compare your situation to what is available. You may find opportunities for savings that you did not know existed.
The Abatement Process
Massachusetts does not call it an "appeal." Instead, you apply for an "abatement" (a reduction in your assessed value).
Step 1: File for Abatement (by February 1)
File an abatement application with your local board of assessors. The form is available from the assessor's office or the municipality's website. Include:
- Your property details and parcel ID
- Current assessed value
- Your opinion of fair cash value
- Comparable sales supporting your opinion
The board has 3 months to act on your application. If they do not respond within 3 months, the application is deemed denied.
Step 2: Appellate Tax Board (if Denied)
If the local board denies your abatement (or does not respond within 3 months), you can appeal to the Massachusetts Appellate Tax Board within 3 months of the denial (or deemed denial). There is a $50 filing fee for residential properties.
The ATB conducts a more formal hearing. You present evidence, the assessors present theirs, and the ATB issues a written decision.
Massachusetts Exemptions
| Exemption | Benefit | Eligibility |
|---|---|---|
| Residential exemption | Varies by community (shifts tax burden to commercial) | Owner-occupied primary residence (adopted by some municipalities) |
| Senior (Clause 41C) | Up to $1,000 exemption | Age 65+, income under limit, asset limits |
| Blind (Clause 37A) | $500 exemption | Legal blindness |
| Disabled Veteran (Clause 22) | $400-$1,500 depending on disability percentage | Veterans with service-connected disability |
| 100% Disabled Veteran (Clause 22E) | Full exemption | 100% disability rating |
| Senior Tax Deferral (Clause 41A) | Defer taxes until property transfers | Age 65+, income under limit |
Some municipalities have adopted a residential exemption that shifts part of the tax burden from residential to commercial properties. If your municipality offers this, it is applied automatically to owner-occupied homes.
Do not assume you are automatically enrolled. Most exemptions require an application, and many homeowners lose years of savings simply because they never filed. Contact your county assessor's office or check their website for the application form. Bring proof of eligibility (age verification, disability documentation, veteran status, etc.) and file well before the deadline.
If you qualify for multiple exemptions, apply for all of them. In most jurisdictions, exemptions stack. A senior homeowner who is also a veteran can often claim both exemptions simultaneously, doubling the savings.
Massachusetts Tax Bill Structure
Massachusetts uses a quarterly billing system:
- Preliminary bills (Q1 and Q2): Based on the prior year's tax. These are estimated payments.
- Actual bills (Q3 and Q4): Reflect the current year's assessed value and tax rate. The total tax minus preliminary payments equals what you owe in Q3 and Q4.
The third quarter bill (arriving in December-January) is where you first see your new assessed value for the year. This is when you need to decide whether to file for an abatement.
Even if you are appealing your assessment, you typically must pay your tax bill on time. Failing to pay while appealing can trigger penalties and interest charges that offset any savings from a successful appeal. Pay the amount due, and if your appeal succeeds, you will receive a refund or credit for the overpayment.
If paying the full amount creates a hardship, check whether your jurisdiction offers installment plans or partial payment options. Some counties allow you to pay the undisputed portion while your appeal is pending.
Your Next Steps
Here is what to do right now:
- Check your state's deadline. Use the tables above to find your state's specific dates. If your deadline is within the next 60 days, start preparing immediately.
- Open your assessment notice. If you received one recently, read it today. Do not set it aside. Check the assessed value, property details, and the appeal deadline printed on it.
- Gather comparable sales. If your assessed value looks too high, pull 3 to 5 recent sales of similar homes in your area. This is the single most important piece of evidence for any appeal.
- File for exemptions you have not claimed. Many homeowners miss exemptions simply because they never applied. Check what is available in your state and file before the deadline passes.

Frequently Asked Questions
What if I just bought my home?
Massachusetts does not automatically reassess upon sale, but the annual reassessment will reflect recent sales in your area, potentially including yours. If the new assessment exceeds your purchase price and the sale was recent and arms-length, your purchase price is strong evidence in an abatement application.
Is the February 1 deadline firm?
Yes. Massachusetts law sets February 1 (or 30 days after the third quarter tax bill is sent, whichever is later) as the deadline. There are no extensions.
How much does an abatement save?
Massachusetts has an average effective rate of about 1.12%. On a $500,000 home, a 10% reduction saves about $560 per year. In higher-rate communities, savings can be larger.
The most effective strategy combines multiple approaches. Start with exemptions since they are free to file and provide guaranteed savings if you qualify. Then check your property record for errors since corrections are straightforward and hard for the assessor to dispute. Finally, if your assessed value still exceeds your home's market value, file a formal appeal with comparable sales data.
Each of these steps compounds. A homeowner who claims an overlooked exemption, corrects a square footage error, and wins an appeal on comparable sales can reduce their annual tax bill by 20% or more. That savings repeats every year until the next reassessment.
