Personal Property Tax
Movable, physical property is subject to the personal property tax, but there are exceptions. Learn more about personal property tax.
Community Preservation Act (CPA) Surcharge
In November 2016, Boston voters approved the Community Preservation Act (CPA) by voting “yes” on Ballot Question 5. By adopting the act, the City has created a Community Preservation Fund.
The City finances the fund in part by a 1% property tax-based surcharge on residential and business property tax bills. You may see the surcharge on your property tax bills.
Taxpayer Referral and Assistance Center
"TRAC" offers a "one-stop" service at City Hall for Boston taxpayers on tax-related matters.
