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.

Community Preservation Act surcharge

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 beginning with the Fiscal Year 2018 first-quarter tax bill in July 2017.
