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.

Property taxes when buying or selling in Wellesley

When you sell, you pay the Massachusetts deeds excise of $4.56 per $1,000 of sale price at closing — a separate transfer tax. Taxes are prorated between buyer and seller at closing.

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.

Does Wellesley use a split tax rate?
No. Wellesley keeps a single uniform tax rate rather than adopting a split rate. Every property class — residential and commercial alike — is taxed at the same $10.17 per $1,000. Towns that adopt a split rate, like Newton or Watertown, shift more of the tax levy onto commercial property; Wellesley does not.
What does a typical Wellesley home pay in property tax?

A Wellesley home assessed at $1,675,000 owes $17,035 per year at the FY2026 rate of $10.17 per $1,000. That figure is based on assessed value, which the town sets and which typically trails current market value.
Is property tax based on what I paid for my home?
No. Massachusetts property tax is based on assessed value, set by the town as of January 1 of the prior year — not on your purchase price. In a rising market, assessments typically lag actual market values.
When are Wellesley property tax bills due?
Wellesley bills quarterly, like other Massachusetts towns. Preliminary bills are due August 1 and November 1; actual bills, reflecting the final FY2026 rate, are due February 1 and May 1.
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 Wellesley property tax assessment?
Yes. File an abatement application with the Wellesley 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 Wellesley Assessors for current programs.
How does property tax affect buying or selling in Wellesley?
Buyers should factor the annual tax into their carrying cost and loan qualification. Sellers pay the Massachusetts deeds excise of $4.56 per $1,000 of sale price at closing, separate from property tax. We prepare a full net-cost estimate for every Wellesley transaction.
