How do I pay my property taxes?

Municipal Tax Collector (city or town level - each of Massachusetts's ~351 cities and towns)

Step by Step

How to do it

Locate your tax bill: Massachusetts cities and towns issue quarterly or semi-annual tax bills; most larger cities use quarterly billing; some smaller towns use semi-annual
Review your bill for the correct amount, parcel number, and due dates
Choose your payment method: in person at the city/town Tax Collector's or Treasurer's office, by mail, or online through your municipality's payment portal
Pay by the quarterly or semi-annual due dates - varies by municipality; typical quarterly schedule:
FIRST QUARTER (PRELIMINARY BILL): August 1
SECOND QUARTER (PRELIMINARY BILL): November 1
THIRD QUARTER (ACTUAL BILL - this is the key abatement deadline trigger): February 1
FOURTH QUARTER (ACTUAL BILL): May 1
NOTE: Some smaller towns use semi-annual; some dates shift by a few days - verify with your municipality
Retain receipt as proof of payment

Massachusetts Notes

Massachusetts property taxes are ENTIRELY MUNICIPAL - no county property tax; no state property tax.
Assessment date: January 1 each year (the "lien date"); applies to the fiscal year beginning the following July 1.
PROPOSITION 2½: Massachusetts law limits the total amount of property taxes a municipality can levy (2½% of total assessed value) and limits increases to 2½% annually; this cap protects against dramatic year-over-year tax increases.
RESIDENTIAL EXEMPTION: A local-option exemption under Ch. 59 §5C allowing cities/towns to shift tax burden from owner-occupied residential to commercial properties; Boston, Cambridge, and some other cities use this significantly - check your city's website.
HOMEOWNER EXEMPTION (Circuit Breaker): Massachusetts offers a state income tax credit (Schedule CB) for eligible seniors 65+ who pay more than 10% of their income in property taxes; file with state income tax return.
SENIOR TAX WORK-OFF PROGRAMS: Many municipalities offer senior residents the ability to reduce property taxes through volunteer work; contact your city/town.
Massachusetts has state certification of assessors' methodologies every 3 years (triennial certification by Department of Revenue).
