The property tax rate in Weston, MA for fiscal year 2026 is $10.88 per $1,000 of assessed value, a single uniform rate that applies to both residential and commercial properties.1Weston, MA. Tax Rate History On the town’s median residential assessment of roughly $1,683,500, that works out to about $18,316 a year.
Where the Rate Has Been Headed
The FY2026 rate is slightly lower than FY2025’s $11.10 and FY2024’s $11.12.1Weston, MA. Tax Rate History A falling rate doesn’t automatically mean a smaller bill. Weston’s total assessed values have been climbing, so the town can collect the same or more revenue at a lower rate per dollar. If your home’s assessment rose faster than the rate dropped, your bill still went up.
Calculating What You Owe
Divide your assessed value by 1,000, then multiply by the rate. A home assessed at $1,500,000 comes to 1,500 × $10.88, or $16,320 for the year. A home at the median assessment of about $1,683,500 owes roughly $18,316.
The assessed value is not what you paid for the house and not what Zillow shows. It’s the figure the Board of Assessors assigned based on comparable sales and your property’s physical characteristics as of the prior January 1. If that number looks wrong, there is a process for challenging it.
How Weston Sets the Rate
Each year the Select Board holds a public tax classification hearing with the Board of Assessors. Officials decide whether to tax all property at a single rate or shift more of the burden onto commercial and industrial owners. Weston has consistently chosen a uniform rate, so residential and commercial owners pay the same amount per $1,000 of value. The vote then goes to the Massachusetts Department of Revenue for certification before bills are issued.
How Your Property Is Assessed
Massachusetts law requires every property to be assessed at its “fair cash valuation,” meaning what it would sell for on the open market between a willing buyer and seller.2General Court of Massachusetts. Massachusetts General Laws Part I, Title IX, Chapter 59, Section 38 Weston’s assessors use a mass appraisal system that pulls recent sale prices across town and adjusts every property’s value each year based on market trends.
Properties also get physically inspected on a rolling schedule. State guidance calls for a visit at least once every ten years, though assessors can come more often.3Mass.gov. Ask DLS: Assessor Inspections Inspections verify square footage, room counts, condition, and any additions or renovations. Enclose a porch or finish a basement, and expect an adjustment.
Supplemental Bills After Major Work
If a property’s value jumps by more than 50% because of new construction or a major renovation that triggers an occupancy permit after January 1, the town issues a supplemental tax bill. The amount is the value of the improvement multiplied by the current rate, prorated for the portion of the fiscal year remaining after the permit was issued. It comes on top of the original bill. If your mortgage servicer handles taxes through escrow, you’re responsible for telling them about the supplemental charge.
Exemptions That Reduce the Bill
Massachusetts offers several personal exemptions that cut a fixed dollar amount off your tax bill. They are granted one fiscal year at a time, so you reapply annually. Eligibility is measured as of July 1 of the fiscal year.4Weston, MA. Personal Exemptions
Seniors
Under Clause 41C, homeowners age 70 or older can receive a $1,000 reduction. You must have owned and occupied your home (or another Massachusetts property) for at least five years and been a state resident for at least ten consecutive years. Income and asset limits apply and are updated periodically. For FY2026, gross income (after a Social Security deduction) must fall below roughly $30,000 for a single filer or about $42,000 for a married couple. Assets, excluding the home itself, registered vehicles, and personal effects, cannot exceed about $50,000 for a single filer or $62,000 for a married couple.
Veterans
Disabled veterans and their surviving spouses qualify for exemptions that scale with the severity of the disability. A veteran with a service-connected rating of at least 10% receives $400 off. Loss of use of one hand, foot, or eye in the line of duty brings $750. A 100% disability rating is worth $1,000. Loss of both hands, feet, or eyes brings $1,250, and veterans requiring specially adapted housing receive $1,500. Surviving spouses of service members who died in active duty or went missing may qualify for a full exemption.5Mass.gov. Local Property Tax Exemptions for Veterans Have your DD Form 214 or equivalent military documentation ready when you apply.
Other Categories
Exemptions also exist for legally blind residents and for certain surviving spouses. Applications are available through the Weston Assessors’ Office. You’ll need your parcel ID, current assessment details, and documentation specific to the exemption you’re claiming.
If You Think Your Assessment Is Too High
You can file an abatement application with the Board of Assessors. The deadline is the day the third-quarter tax bill is due, which in Weston typically falls on February 1. Miss that date and you lose the right to challenge your assessment for that fiscal year.
Strong abatement cases rest on concrete evidence: a recent independent appraisal showing a lower value, comparable sales of similar properties that closed for less, or documentation of structural problems like foundation issues or a failing roof that the assessors may not have accounted for. Believing your taxes are too high isn’t enough. You have to show that the assessed value doesn’t reflect what the property would actually sell for.
The Board of Assessors has three months to act. If they grant the abatement, your bill is adjusted. If they deny it, or fail to act within three months (which counts as a denial), you can appeal.
Appealing to the State
You have three months from the date of denial to file with the Massachusetts Appellate Tax Board. If your application was deemed denied because the assessors never acted, the three-month appeal window starts when that initial waiting period ends.6Mass.gov. Real Estate Tax Appeals: A Helpful Guide for Taxpayers and Assessors The Appellate Tax Board hears disputes independently of the local assessors. The process is more formal than Town Hall, and many homeowners bring in an attorney or tax consultant, particularly for high-value properties. You must pay your taxes in full while the appeal is pending; winning results in a refund, not permission to withhold payment.
Paying the Bill
Weston bills quarterly. The due dates for the current cycle are August 1, November 3, February 2, and May 1.7Weston, MA. Assessors’ Office Key Dates The first two quarters are preliminary bills based on the prior year’s tax. Once the new rate is set, the third and fourth quarter bills reflect the actual amount owed, with credit for what you already paid.
You can pay online through the town’s portal, which runs on City Hall Systems.8Weston, MA. Pay Taxes and Bills or Renew Online Credit and debit payments carry a percentage-based convenience fee, and electronic checks carry a flat fee. Those fees go to the payment processor, not the town. You can also mail a check to the lockbox address or drop one at the Treasurer’s office to avoid the fee.
Late payments accrue interest at 14% per year from the original due date.9General Court of Massachusetts. Massachusetts General Laws Part I, Title IX, Chapter 59, Section 57 On a quarterly bill around $4,500, a few months of delay adds up quickly. Prolonged nonpayment can lead to a tax taking recorded against your property and, eventually, foreclosure through the Land Court.10General Court of Massachusetts.
