CPA Background

The Community Preservation Act (CPA) was created by state law (G.L. c. 44B) to help cities and towns preserve the character of their community. In 2001, Cambridge residents voted to adopt the CPA locally, which allowed the City to implement a 3% surcharge on Property Tax bills to fund eligible projects.

The Commonwealth of Massachusetts provides "matching" funds in addition to those raised locally by the surcharge. The percentage of the state match varies from year to year, depending on two factors: the amount of fees paid at Registries of Deeds throughout the state, and the number of communities that have adopted the CPA locally (thereby receiving a share of the state match).

Each year, the City is required to spend at least 10% of its annual CPA revenues on each category - open space, historic preservation and community housing. The remaining percentage can be used towards any of the three funding categories.

Through FY27, the City has appropriated/reserved a total of $347.9 million for CPA projects, including $278.5 million for affordable housing initiatives. To date, the City has allocated $75.5 million in state matching funds, $229.4 million from local surcharges, and $43.0 million from the CPA Fund Balance.

How much is the Cambridge Surcharge and how is it calculated?

A 3% surcharge is levied against your property tax amount, not the value of the property. For example, a CPA surcharge of 3 percent on a real property tax bill of $1,000 would be $30, or 3 percent of $1,000, per year. Note: the numbers below are provided as an illustration. Actual CPA surcharges depend on assessed values, tax rates, and residential exemptions, which are set on an annual basis.

1. Owner-Occupied Residential Property

Prop Value	City Residential Exemption	CPA Residential Exemption	Tax Rate	CPA Surcharge	Calculation
$1,000,000	$450,000	$100,000	$6.00/$1,000	$81.00	(Value - Res Exempt - CPA Res Exempt) x Tax Rate x 3%

2. Residential Property, Not Owner-Occupied

$1,000,000	N/A	$100,000	$6.00/$1,000	$162.00	(Value - CPA Res Exempt) x Tax Rate x 3%

3. Mixed-Use Property, Not Owner-Occupied
