Windsor'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. Windsor applies the same $9.43 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 $9.43.
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.
Windsor's FY 2027 rate
Windsor is one of 23 cities and towns whose FY 2027 rate was already in the Division of Local Services table on October 26, 2026: $11.02 per $1,000 residential. That is $1.59 (16.86%) higher than the FY 2026 rate, and on a $300,000 assessment it comes to $3,306.00, $477.00 more than the FY 2026 bill at the same assessment. Each fiscal year's rate applies to that year's assessed values, set as of the January 1 before it, so the change in an actual bill also depends on how the assessment moved. The rankings on this site stay on FY 2026 until every city and town has a FY 2027 rate.
Windsor's rate in FY 2025 and FY 2026
The residential tax rate fell $1.91 per $1,000 (16.84%) from $11.34 per $1,000 in FY 2025, and the same $300,000 assessment owes $573.00 less than at last year's rate. In FY 2025 Windsor ranked 232nd. The commercial rate went from $11.34 to $9.43. 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.

Each bill is the assessed value divided by 1,000 and multiplied by $9.43, 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 Windsor assessment
In Massachusetts the first step is an abatement application to Windsor'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 Windsor's FY 2026 residential rate each $10,000 of assessment costs $94.30 a year.
