Property Tax in Seekonk, MA: Rates, Due Dates, and Appeals

The Seekonk MA property tax rate for fiscal year 2026 is $12.27 per $1,000 of assessed value on residential property, and $25.77 per $1,000 on commercial and industrial property.¹ A home assessed at $400,000 owes roughly $4,908 for the year. Bills come quarterly, and the town offers exemptions and an abatement process that can lower what you owe, provided you meet the deadlines.

Current Rates and What You’ll Owe

Seekonk uses a split tax rate, so residential and commercial properties are taxed differently. The certified FY2026 rates are:

Residential: $12.27 per $1,000 of assessed value
Commercial and industrial: $25.77 per $1,000 of assessed value
Personal property: $25.74 per $1,000 of assessed value

To estimate your bill, divide your assessed value by 1,000 and multiply by the rate that applies to your property. A home assessed at $350,000 owes $4,294.50 for the year. A commercial property at that same value owes $9,019.50.¹

When Your Tax Bills Are Due

Seekonk bills property taxes on a quarterly schedule. The first two quarters are preliminary bills based on last year’s taxes. The second two are actual bills that reflect the current year’s assessment and newly certified rate.²

First quarter (preliminary): August 1
Second quarter (preliminary): November 1
Third quarter (actual): February 1
Fourth quarter (actual): May 1

The two preliminary payments together add up to about what you paid for the entire previous year. When the actual bills arrive, the town subtracts those preliminary payments from your true annual tax and splits whatever is left between the February and May bills.² If your assessment went up, those two bills will be noticeably bigger than the first two.

How the Rate Gets Set

The Seekonk Board of Assessors values each property at its full and fair cash value, meaning what a willing buyer would pay a willing seller on the open market. Massachusetts General Laws Chapter 59 requires this standard statewide.³ Assessors rely on recent comparable sales, property characteristics, and local market conditions.

Each year, residents vote on a municipal budget at town meeting that determines how much revenue the town needs to raise from property taxes. The assessors divide that amount by the town’s total taxable value to produce the rate per $1,000. The Massachusetts Department of Revenue must certify the rate and underlying assessments before any bill goes out.

Proposition 2½ caps how fast the total tax levy can grow. The town’s overall property tax collection cannot increase by more than 2.5 percent over the prior year’s limit, plus revenue from new construction.⁴ Voters can override the cap at the ballot box, but otherwise this law keeps annual tax growth relatively predictable even when property values climb.

Exemptions That Can Lower Your Bill

Massachusetts law provides property tax exemptions for several groups of residents, and Seekonk administers them locally. These exemptions reduce your bill by a set dollar amount. You can generally claim only one exemption per property per year.⁵

Seniors

Under Clause 41C, homeowners who turned 70 before the start of the fiscal year may qualify for an exemption of up to $500. You need to have lived in Massachusetts for at least 10 years and owned and occupied your home (or another Massachusetts property) for at least five years. Income and asset limits apply: prior-year gross income generally must fall below $13,000 if single or $15,000 if married, and total estate excluding your home cannot exceed $28,000, or $30,000 for married couples.⁶ Towns can adopt higher limits, so check with the Seekonk Assessors’ office for the local thresholds.

Separately, Massachusetts offers a Senior Circuit Breaker Tax Credit on your state income tax return. For tax year 2025, the maximum credit was $2,820, available to seniors 65 and older with total income below $75,000 (single), $94,000 (head of household), or $112,000 (married filing jointly).⁷ This one is claimed on your state return, not through the town.

Veterans

Disabled veterans qualify for exemptions that scale with the severity of their service-connected disability. The base exemption under Clause 22 is $400 for veterans with at least a 10 percent disability rating or those who received a Purple Heart. Veterans who lost a limb or sight in one eye receive up to $750, and amounts increase for more severe injuries, up to a full exemption for surviving spouses of service members killed in action.⁶ Bring your military discharge papers and VA documentation when you apply.

Blind Residents and Surviving Spouses

Legally blind residents and surviving spouses who meet certain criteria also qualify for exemptions under Chapter 59, Section 5. Each category requires supporting documentation, such as certification from the Massachusetts Commission for the Blind. Applications are available at the Seekonk Assessors’ office in Town Hall.

Challenging Your Assessment

If you think the town overvalued your property, you can file an abatement application asking the Board of Assessors to reduce your assessed value and your tax bill. The deadlines are strict, and missing them means losing your right to appeal.

You file using the state’s official form (State Tax Form 128), available at the Assessors’ office or on the Department of Revenue’s website. Your application must reach the Board of Assessors by the due date of the first actual tax bill for the fiscal year. For Seekonk’s quarterly schedule, that date is February 1.⁸ You can deliver it in person or send it by certified mail.

Your application should explain why the assessment is wrong, with specific evidence: recent sales of comparable homes that came in lower, documentation of property defects, or proof that similar neighborhood properties are assessed at less per square foot. Vague complaints that the bill is too high rarely succeed.

One point that catches people out: filing an abatement does not pause your obligation to pay the tax bill. You have to keep paying on time while the application is pending, or you risk losing the right to appeal if it is denied.⁹ If the abatement is granted, the town refunds the overpayment.

Appealing to the Appellate Tax Board

The Board of Assessors has three months from the date you file to act on your application. If they don’t respond within that window, the application is automatically deemed denied by operation of law.¹⁰ Whether the denial is formal or automatic, you then have three months to file an appeal with the Massachusetts Appellate Tax Board.

The ATB offers a formal procedure for complex cases and an informal procedure that works for most residential disputes. Forms and fee information are on the ATB’s website. One trap worth flagging: if your tax bill exceeds $5,000, your payment must physically be in the collector’s hands by the due date to preserve your appeal rights. A postmark alone is not enough.¹¹

What Happens If You Pay Late

Missing a quarterly deadline triggers interest immediately. Under Massachusetts law, unpaid property taxes accrue interest at 14 percent per year, calculated from the original due date.¹² That is higher than most credit cards, and it compounds quickly on a balance of several thousand dollars.

The town’s first formal step is a written demand notice, which adds a fee of up to $30 on top of the overdue amount.¹² If the balance remains unpaid, the town can initiate a tax taking, which places a lien on your property recorded at the Bristol County Registry of Deeds. That lien attaches to the property’s title, so you cannot sell or refinance until the debt, interest, and fees are fully paid.

A tax taking is not the end of ownership. Massachusetts law gives property owners a right of redemption: you can reclaim clear title at any time before the town files a foreclosure petition by paying the full tax title balance plus 8 percent interest on the original amount, along with any added charges.¹³ The treasurer can also grant payment plans. If you fall behind, call the Seekonk Collector’s office early. The earlier you start the conversation, the more options you have.

If Your Mortgage Lender Pays Your Taxes

Most homeowners with a mortgage don’t pay the town directly. The lender collects a portion of the estimated annual tax each month as part of your mortgage payment and holds it in escrow, then pays the quarterly bills on your behalf.

Federal law caps what your lender can keep in that account. Under the Real Estate Settlement Procedures Act, your servicer can hold a cushion of no more than one-sixth of annual escrow disbursements, roughly two months of reserves.¹⁴ Your servicer must also send you an annual escrow analysis showing what was collected, what was paid, and whether the account has a shortage or surplus.¹⁵

When Seekonk’s rate changes or your property is reassessed higher, the analysis often shows a shortfall, and the lender raises your monthly payment to cover it. That is the most common reason mortgage payments climb for homeowners who haven’t refinanced. Review the annual statement carefully, confirm the assessed value matches what the town recorded, and if you win an abatement, notify your servicer so the escrow can be adjusted.

Deducting Seekonk Property Tax on Your Federal Return

If you itemize on your federal return, you can deduct property taxes paid to Seekonk. The deduction falls under state and local taxes, which also includes state income taxes. For 2026, the combined SALT deduction is capped at $40,000 for most filers, or $20,000 if married filing separately, and cannot drop below $10,000 regardless of income.¹⁶

For many Seekonk homeowners, Massachusetts state income tax alone eats a significant share of that cap, leaving less room for property tax. Anything above the cap gives you no federal benefit. You can only deduct property taxes in the year you actually pay them, and special assessments for local improvements like sidewalks or sewer lines generally don’t qualify unless they cover maintenance or repairs.¹⁶ The standard deduction has been high enough in recent years that many homeowners do better by not itemizing, so run the numbers both ways.
