About Massachusetts property tax

Massachusetts property tax is billed and collected county by county, so the collector — not the state — issues the bill. Cities and towns that adopt G.L. c.59 s.57C bill quarterly on Aug 1, Nov 1, Feb 1 and May 1, while non-adopting towns use the semiannual Nov 1 / May 1 dates.
