The Newton Community Preservation Act Surcharge: What It Is and What It Funds

Since 2001, Newton has added a Community Preservation Act (CPA) surcharge of 1% to property tax bills, funding affordable housing, historic preservation, open space protection, and outdoor recreation projects citywide. Unlike many other Massachusetts communities that have adopted the CPA, Newton did not adopt the standard exemptions available under the law — most notably, an exemption for the first $100,000 of a property's assessed value, which a number of other CPA towns do offer.

What is the Community Preservation Act, generally?

The CPA is a Massachusetts state law that lets individual cities and towns opt in, by local vote, to add a surcharge to property tax bills — within a range set by the statute — dedicated specifically to four categories: community housing, historic preservation, open space protection, and outdoor recreation. Adopting it is entirely a local decision; nothing in state law requires any town to have one, and towns that have adopted it vary both in their surcharge rate and in which exemptions they layered on top of it.

How much is Newton's surcharge, and how is it calculated?

Newton's surcharge is 1% of the property tax bill, adopted by local vote in 2001. Because Newton did not adopt the exemption many other CPA communities did, the surcharge generally applies to the full assessed value of a property, without the first $100,000 carved out the way it is in towns that added that exemption. If you're comparing your Newton tax bill to a friend's bill in a neighboring CPA town, this is one reason the CPA line item may not track the same way between the two.

What does the surcharge actually fund?

The four categories set by state law:

• Community housing, including affordable housing projects
• Historic preservation, including restoring and maintaining historic properties and records
• Open space protection, including conservation land and parks
• Outdoor recreation

A local Community Preservation Committee reviews project proposals and recommends funding allocations, which are ultimately approved through Newton's local legislative process.

If you're evaluating what your Newton property tax bill actually funds beyond the base tax rate, the CPA surcharge line is worth understanding on its own — it isn't a fee for a specific service you personally receive, but a dedicated funding stream for citywide housing, preservation, and open space projects, adopted and renewable only by future town vote.

Is there any way to reduce or avoid the surcharge?

Some Massachusetts communities offer exemptions for low-income households, low-to-moderate-income seniors, or the first portion of assessed value, but Newton's version of the CPA does not include these standard exemptions. If your circumstances have changed since 2001 and you believe this deserves another look, that's a question for Newton's Community Preservation Committee or your city councilor — not something adjustable at the level of an individual tax bill.

How does this relate to your regular property tax assessment?

The CPA surcharge is calculated as a percentage of your existing property tax bill, so it moves with your assessed value the same way your base tax does — it isn't a separately assessed tax in its own right.
