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.
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 |

| 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.
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.
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.
