Massachusetts property tax deadlines
12 sourced dates. 14 of 14 Massachusetts counties have at least one.
Massachusetts counties don't handle property tax. Each city and town bills and collects it, and the town's assessors handle abatements and exemptions, under chapter 59 of the General Laws. Most towns bill four times a year. The exact dates, weekend rules and interest are on your town's bill.
