Massachusetts property tax

Massachusetts’s average effective property tax rate is about 1.14% of a home’s value per year. Counties and municipalities set their own rates and assessments, so your actual bill can be higher or lower. Use your county assessor’s rate for precision — the figures here are statewide averages that change over time.

How it’s calculated

Annual property tax = home value × effective property tax rate. The monthly figure divides that by 12. This page uses Massachusetts’s statewide average effective rate by default — replace it with your county or city rate for a closer estimate.

Effective rates are statewide averages (statewide average) and vary widely by county and municipality. Check your local assessor for an exact figure. Estimate only.
