Westport's FY 2026 rates by class of property
The Division of Local Services lists a rate for each class of property, and each city and town decides whether to tax the classes alike. Westport applies the same $7.28 per $1,000 to residential, commercial and industrial property, as 223 of the 351 cities and towns do. Personal property, such as business equipment, pays $7.28.
Massachusetts assessments are meant to be fair cash value as of January 1 before the fiscal year: for FY 2026, January 1, 2025 (Massachusetts Appellate Tax Board). Because every city and town measures against the same standard, the residential rate is a fairer comparison between Massachusetts towns than a rate is in a state where assessments sit at different shares of value. The bill on this page is before the exemptions and credits an owner may qualify for.
Westport's rate in FY 2025 and FY 2026
The residential tax rate fell $0.17 per $1,000 (2.28%) from $7.45 per $1,000 in FY 2025, and the same $300,000 assessment owes $51.00 less than at last year's rate. In FY 2025 Westport ranked 319th. The commercial rate went from $7.45 to $7.28. Each year's rate applies to that year's assessed values, so a lower rate on a higher assessment can still mean a higher bill.
Tax on common assessed values in Westport
| Assessed value | FY 2026 bill | At the FY 2025 rate | Versus MA median rate |
|---|---|---|---|
| $200,000 | $1,456.00 | $1,490.00 | −$1,032.00 |
| $300,000 | $2,184.00 | $2,235.00 | −$1,548.00 |

| $750,000 | $5,460.00 | $5,587.50 | −$3,870.00 |
Each bill is the assessed value divided by 1,000 and multiplied by $7.28, before exemptions, credits or special charges. These are assessed values, not sale prices, though in Massachusetts the assessment is meant to be the property's fair cash value on January 1, 2025. The last column is the difference from the same assessment at the $12.44 per $1,000 state median.

Appealing a Westport assessment
In Massachusetts the first step is an abatement application to Westport's board of assessors. Where bills are quarterly it is due by February 1, the due date of the first actual installment; where bills go out twice a year it is generally 30 days after the bill is mailed (G.L. c. 59 § 59). The assessors have three months to act, after which the application is deemed denied, and an appeal to the Appellate Tax Board must be filed within three months of their decision (G.L. c. 59 §§ 64, 65), with the tax paid on time unless the Board waives it. The question is fair cash value on January 1: on Westport's FY 2026 residential rate each $10,000 of assessment costs $72.80 a year.
