How does Massachusetts property tax work?

Massachusetts property tax is set locally and billed quarterly. Each town sets its own rate per $1,000 of assessed value, with the assessment fixed as of January 1 of the prior year. Statewide rules:

  • •Assessed, not market. Tax is based on assessed value, not your purchase price.
  • •Proposition 2½. A town's total levy can grow only 2.5% per year, plus new growth, unless voters override.
  • •Quarterly bills. Preliminary bills due August 1 and November 1; actual bills due February 1 and May 1.
  • •Abatements. File with the Board of Assessors after the Q3 actual bill, by the printed deadline.

FY2026 rates per $1,000 of assessed value. Median assessed value is the median of residential properties (single-family, condo, and small multi-family) on each town's assessor roll from our 135,000-property dataset; “tax on median home” is that median × the residential rate, before any exemptions. Assessed values typically trail market prices.

What is Proposition 2½?
Proposition 2½ is a Massachusetts law that caps a town's total property tax levy growth at 2.5% per year, plus new growth from new construction, unless voters approve an override. It limits how fast the overall levy can rise.
Can I appeal my Dedham property tax assessment?
Yes. File an abatement application with the Dedham Board of Assessors after the Q3 actual tax bill is issued, by the deadline printed on that bill. An abatement challenges your assessed value, not the tax rate. Some Massachusetts communities also offer exemptions for seniors, veterans, and owner-occupants — check with the Dedham Assessors for current programs.
