Tewksbury Property Tax Rate: Exemptions, Deadlines, and Appeals

The Tewksbury property tax rate for fiscal year 2026 is $12.56 per $1,000 of assessed value on residential property and $24.90 per $1,000 on commercial, industrial, and personal property.¹ A home assessed at $500,000 produces a base tax of about $6,280 before the Community Preservation Act surcharge or any exemptions. Rates reset each fiscal year based on the town budget, total assessed values, and how the Select Board divides the levy between the residential and commercial classes.

How the Split Tax Rate Works

Tewksbury does not use a single uniform rate. Every fall the Select Board holds a classification hearing and votes on how to split the total tax levy between residential property and the commercial/industrial/personal class. Shifting more burden onto business property lowers the residential rate and raises the commercial rate. The Board of Assessors supplies the data; the Select Board casts the final vote. The authority for this comes from M.G.L. c. 40, § 56.

Recent history shows how the rates move:¹

FY2026: $12.56 residential / $24.90 commercial
FY2025: $13.22 residential / $24.97 commercial (revaluation year)
FY2024: $13.39 residential / $25.24 commercial

The residential rate fell in FY2026 because assessed values rose, spreading the same levy across a bigger base. A lower rate does not automatically mean a lower bill. If your home’s assessed value climbed by more than the rate dropped, your bill goes up anyway. That is the piece a lot of homeowners miss when they see a rate cut announced.

Proposition 2½ caps the whole system. Total property tax revenue cannot exceed 2.5% of the town’s aggregate assessed value, and the annual levy can grow no more than 2.5% over the prior year’s maximum plus new growth from construction and similar changes.² Voters can approve an override at the ballot box, but without one, the cap limits how fast bills can rise.

Calculating Your Bill

The formula is simple. Divide the assessed value by 1,000, then multiply by the tax rate. A house assessed at $450,000 at the FY2026 residential rate: 450 × $12.56 = $5,652 in base property tax.

Then add the Community Preservation Act surcharge. Tewksbury charges 1.5%, and the first $100,000 of assessed value is exempt from the surcharge calculation.³ On that same $450,000 home, the surcharge applies to $350,000 of value: 350 × $12.56 × 1.5% = about $65.94. CPA money funds open space, affordable housing, historic preservation, and recreation projects.⁴

Total annual bill on that $450,000 home: roughly $5,718, or about $1,429 per quarterly installment.

Assessed value itself is set by the Board of Assessors as of January 1 each year and is meant to reflect fair cash value — what a willing buyer would pay a willing seller on the open market under M.G.L. c. 59, § 38.⁵ The assessors work from recent sales, building permits, and comparable properties.

When Bills Are Due

Tewksbury bills quarterly.⁶ The four due dates are:

August 1 (preliminary, Q1)
November 1 (preliminary, Q2)
February 1 (actual, Q3)
May 1 (actual, Q4)

August and November bills are preliminary and based on the prior year’s total tax. Once the new fiscal year’s rate is set, the February and May bills adjust to the actual amount owed, minus what was already paid.⁷

You can pay online, by mail, or in person at the Collector’s office. Electronic check payments through the online portal are free. Credit card payments carry a convenience fee of up to 2.95% with a $1 minimum, and the fee is non-refundable.⁸ On a $1,500 quarterly payment, that is about $44 in fees — enough to make the free e-check route worth setting up.

What Happens If You Pay Late

Interest starts the moment you miss a due date. The statutory rate is 14% per year, calculated from the original due date, and it is not negotiable.⁹ On a $6,000 annual bill, a three-month lag on one quarterly payment adds roughly $50.

If a balance stays unpaid long enough, the town can start a tax taking. Property taxes create a lien from January 1 of the assessment year, and if taxes remain unpaid 14 days after a formal demand, the collector can levy by sale or taking.¹⁰ Legal fees and recording costs get added to what you already owe. One more consequence catches people off guard: unpaid taxes strip you of the right to appeal your assessment to the Appellate Tax Board. Withholding payment while you fight a valuation ends the fight.

Exemptions That Reduce the Bill

Several statutory exemptions can lower a Tewksbury tax bill for qualifying residents. Each falls under a different clause of M.G.L. c. 59, § 5.

Elderly Exemption (Clause 41C)

Homeowners who turned 70 before the fiscal year began and occupy the property as their primary residence can qualify. The default income limits are $13,000 for a single applicant and $15,000 for a married couple, with a deduction allowed for Social Security and certain government pension income. Asset limits are $28,000 single or $30,000 married, not counting the home itself.¹¹ Applicants must have lived in Massachusetts at least ten years and owned property in the state at least five. Towns can vote to raise these thresholds, so check with the Assessor’s Office for Tewksbury’s current numbers.

Disabled Veteran Exemption (Clause 22)

Veterans with a service-connected disability rating of 10% or more from the VA or their branch of service qualify. The base exemption is $400 in actual taxes or $2,000 of assessed taxable valuation, whichever produces the larger reduction.¹¹ Higher disability ratings and specific circumstances — loss of a limb, blindness, Purple Heart — trigger more generous exemptions under clauses 22A through 22F. Once granted, you do not need to re-prove the disability rating each year unless it changes.

Senior Tax Deferral (Clause 41A)

Homeowners 65 and older who cannot afford the full bill can defer all or part of it. Deferred taxes accrue interest at 8% per year, or lower if the town votes to reduce it.¹¹ The default income limit is $20,000 in prior-year gross receipts, and municipalities can raise that ceiling.¹² Total deferred taxes plus interest cannot exceed 50% of your proportional share of the property’s fair cash value. The balance comes due when the property is sold or transferred, so the deferral acts as a lien settled from sale proceeds.

Filing Deadline

Exemption applications must be filed by April 1 of the fiscal year the tax relates to, or within three months after the tax bill is mailed, whichever is later.¹³ Miss the window and you wait until the next fiscal year. Applications go to the Board of Assessors at Town Hall.

Tewksbury also runs work-off programs that let qualifying seniors and veterans earn credit against their tax bill through volunteer service for the town. The veteran work-off program offers up to $1,000 in annual credit. Contact the Assessor’s Office or the Council on Aging for current eligibility and openings.

Challenging Your Assessment

If your property looks overvalued, or assessed disproportionately compared to similar homes, you can file for an abatement. Valid grounds are an assessment above fair market value, a classification error, or a disproportionate assessment relative to comparable properties.¹⁴

The application must reach the Assessor’s Office by the due date of the first actual tax bill. For FY2026 that deadline is February 2, 2026 at 4:30 p.m., because February 1 falls on a Sunday. Bring evidence: recent appraisals, comparable sales, photos of conditions the assessors did not see, or documentation of errors on your property record card. The Board of Assessors has three months to approve, partially approve, or deny. No action within that window counts as a denial.¹⁴

A denial can be appealed to the Massachusetts Appellate Tax Board within three months of the assessors’ decision (or the deemed-denial date). Filing fees scale with assessed value, from $10 for property assessed at $20,000 or less up to a $5,000 cap on the largest properties.¹⁵ One rule matters more than the fee: you must keep paying your tax bill on time to preserve appeal rights before the Appellate Tax Board.¹⁴
