About Property Taxes in Massachusetts
Massachusetts property taxes are administered at the city and town level — the state has no county-level property tax. Each municipality has its own assessors who set values at 100% of fair cash value (market value). Massachusetts reassesses property values annually, though a full statistical analysis is required at least every three years. Property taxes in Massachusetts are moderately high and fund a significant share of public school costs. Major cities like Boston, Cambridge, and Worcester offer significant residential exemptions that substantially reduce taxes for owner-occupants compared to investors.
Payment & Assessment
Most Massachusetts cities and towns issue quarterly tax bills: First and second quarter: Preliminary bills based on prior year's tax; due approximately August 1 and November 1. Third and fourth quarter: Final bills based on current year's assessment; due approximately February 1 and May 1. Some smaller towns bill semi-annually. A demand charge of $30 plus 14% annual interest applies to late payments. Most cities and towns offer online payment through the municipal tax collector's website. Contact your local tax collector for available payment methods.

About Suffolk County
Suffolk County is located in the Commonwealth of Massachusetts, in the United States. As of the 2020 census, the population was 797,936, making it the fourth-most populous county in Massachusetts. The county comprises the cities of Boston, Chelsea, and Revere, and the town of Winthrop. The traditional county seat is Boston, the state capital and the largest city in Massachusetts. The county government was abolished in 1999, resulting in Suffolk County now functioning only as an administrative subdivision of state government and a set of communities grouped together for some statistical purposes. Suffolk County is located at the core of the Boston-Cambridge-Newton, MA-NH Metropolitan Statistical Area as well as the greater Boston-Worcester-Providence, MA-RI-NH-CT Combined Statistical Area.
