TL;DR
Massachusetts property taxes are assessed annually at 100% of fair cash value. Proposition 2.5 limits annual tax levy increases to 2.5% plus new growth. The average effective rate is about 1.12%. Residential exemptions in some cities (notably Boston) shift tax burden to commercial properties. The Senior Circuit Breaker credit provides up to $2,590 for qualifying seniors. Appeal to the local Board of Assessors by the deadline on your tax bill, then to the Appellate Tax Board if needed.
Proposition 2.5
Proposition 2.5 (1980) limits Massachusetts property taxes in two ways:
- Levy ceiling: Total taxes cannot exceed 2.5% of total assessed value in the community
- Levy limit: The tax levy cannot increase more than 2.5% per year, plus taxes on new growth (new construction, improvements)
Override votes can permanently increase the levy limit. Debt exclusions temporarily increase it for approved capital projects.
Assessment
Local assessors value all property annually at full and fair cash value. Massachusetts requires certification by the state Department of Revenue every 5 years, with interim year adjustments.
