FY2026 Rates and How to Calculate Your Bill
The three FY2026 rates per $1,000 of assessed value are:1Patriot Properties. Bellingham WebPro
- Residential: $12.39
- Commercial and industrial: $19.45
- Personal property: $19.37
Divide your assessed value by 1,000 and multiply by the applicable rate. A home assessed at $450,000 owes $5,575.50 for the year. A commercial building at the same assessed value owes $8,752.50. The classification gap is real money if you own both types of property in town.
Year-over-year increases are constrained by Proposition 2½, which caps the total levy at 2.5 percent of full cash value and limits annual levy growth to 2.5 percent plus new growth, absent a voter override.2Massachusetts Municipal Association. An Overview of Proposition 2 1/2
How Your Assessed Value Is Set
Bellingham’s Board of Assessors values every parcel as of January 1 each year at full and fair cash value, meaning roughly what the property would sell for on the open market.3Bellingham, MA. Assessor The state Department of Revenue reviews municipal practices for compliance.4Massachusetts Department of Revenue. FY2025 Assessment Update
Assessors look at recent sales of comparable properties, then adjust for lot size, square footage, bedrooms and bathrooms, age, condition, and any renovations or additions. You can look up your own record and the data driving your valuation through the Patriot Properties database on the town website.
Because the valuation date is January 1, a market shift mid-year won’t show up until the following fiscal year. Expect a lag when neighborhood prices move.
When Property Tax Is Due
Bills come quarterly, with due dates of:5Bellingham, MA. Treasurer / Collector
- August 1 (Q1)
- November 1 (Q2)
- February 1 (Q3)
- May 1 (Q4)
Each bill lists your Map/Lot (Parcel ID) and account number. Keep those; you’ll need them for online payments and for pulling payment history. The Treasurer’s Office can reissue a lost bill.
Online payments are handled through Unibank, linked from the town’s Online Transactions page.6Bellingham, MA. Online Transactions You can also mail a check with the payment coupon to the tax collector’s lockbox, or pay in person at Town Hall during business hours and get a stamped receipt.
What Happens If You Pay Late
Massachusetts charges 14 percent annual interest on overdue property tax, calculated from the original due date.7General Court of Massachusetts. Massachusetts General Laws Chapter 59 – Section 57 The rate is fixed by statute.
Thirty days past due, the town issues a formal demand. If the balance stays unpaid 14 days after that demand, the municipality can record a tax taking at the Registry of Deeds, placing a lien on the property.8Mass.gov. The Tax Lien Foreclosure Process Six to twelve months after the taking, the town can file for foreclosure in Land Court.
You can redeem the property at any point before a final foreclosure judgment by paying the outstanding taxes, interest, and fees. Once judgment enters, your right to the property is gone. Interest at 14 percent compounds fast, so partial catch-up early is far cheaper than waiting.
Challenging Your Assessment
If you think your assessed value is too high, you can file for an abatement with the Board of Assessors between January 1 and February 1 of the fiscal year in question. Miss February 1 and the assessment stands for that year.
Strong applications include recent comparable sales, an independent appraisal, or documentation of conditions the assessor missed: structural damage, environmental issues, or wrong data in the property record such as overstated square footage. Disagreement alone rarely moves the number.
Appeal to the Appellate Tax Board
If the assessors deny your abatement or don’t act within three months, you have three months from the decision (or from the deemed denial) to appeal to the Massachusetts Appellate Tax Board.9Mass.gov. Real Estate Tax Appeals: A Helpful Guide for Taxpayers and Assessors When the tax in dispute is $25,000 or less per fiscal year, the ATB’s small claims procedure applies, with a $50 filing fee.10Mass.gov. Massachusetts State Tax Appeals Larger disputes use the formal procedure, with fees that scale with the abatement sought (minimum $65, maximum $5,000).
One rule catches people off guard: you have to keep paying your tax bill while the appeal is pending. Win, and you get a refund with interest. Skip payments and lose, and you owe the original amount plus 14 percent interest on the unpaid balance.
Exemptions That Can Lower Your Bill
Massachusetts General Laws Chapter 59, Section 5 authorizes several exemptions. None are automatic. Apply through the Bellingham Assessor’s Office by April 1 of the applicable fiscal year, with supporting documentation.
- Clause 41C for seniors 65 and older: $500 exemption. For FY2026, single applicants generally must have no more than $32,180 in gross income or $40,000 in assets excluding the home; married applicants, $48,267 in income and $55,000 in assets.

- Clause 22 for veterans: $400 exemption for a service-connected disability of 10 percent or more, with larger amounts up the disability scale and full exemption for paraplegic veterans or those with 100 percent service-connected blindness. Under the HERO Act, Bellingham may double these amounts or index them to inflation; confirm current local figures with the Assessor’s Office.11Mass.gov. Local Property Tax Exemptions for Veterans

State law gives the tax collector 10 days to issue the certificate after a written request (20 days in smaller towns). The statutory fee is $25, though complex properties can cost more.13General Court of Massachusetts.
