Did a small extra line on your Sudbury tax bill catch your eye? If you are budgeting for a home purchase or planning improvements, that line can raise questions fast. You want to know what it funds, how much to expect each year, and whether your household could qualify for an exemption. In this guide, you will learn how Sudbury’s Community Preservation Act (CPA) surcharge shows up on your bill, how it is calculated, common exemption pathways, and what to do during a purchase or sale. Let’s dive in.
CPA basics you should know
The Community Preservation Act, known as M.G.L. c.44B, lets Massachusetts communities adopt a local property tax surcharge to support four areas: affordable housing, historic preservation, open space, and outdoor recreation. When a town adopts the CPA, it sets a local percentage and creates a Community Preservation Fund that can receive state matching dollars.
In practice, this means Sudbury adds a small surcharge to property tax bills. The town’s Community Preservation Committee recommends projects that align with the CPA’s allowed uses, and the town follows local procedures to fund and administer them. This surcharge is in addition to regular property taxes and is shown as its own line on your tax bill.
Where it appears on your Sudbury tax bill
You do not have to hunt for it. The CPA surcharge typically appears as a separate line item labeled something like “CPA surcharge” or “Community Preservation Surcharge.” It is listed alongside your regular real estate tax. If a parcel is fully tax-exempt and does not receive a real estate tax bill, there will be no CPA surcharge for that parcel.
How the CPA surcharge is calculated
The surcharge is calculated as a percentage of your annual property tax, not as a percentage of your assessed value. Here is the general formula:
- Annual property tax is determined by the town based on assessed value and the tax rate.
- CPA surcharge equals the town’s CPA percentage multiplied by your annual property tax.
Examples to make this real:
- If your annual property tax is $8,000 and the CPA rate is 1.5 percent, the CPA surcharge is $8,000 × 0.015 = $120 per year.
- If the CPA rate were 3.0 percent, that same $8,000 tax would carry a $240 per year surcharge.
Sudbury sets its own CPA percentage by local vote. If you need the current rate for a purchase or refinance, confirm with the Sudbury Assessors’ Office or review the most recent tax bill for the property.
Billing timing and due dates
You will see the CPA surcharge billed in the same cycle as your property taxes. It follows the same bill dates, due dates, and collection process. If a tax bill is adjusted, the surcharge is typically adjusted in step.
Who pays and who may be exempt
Most taxable properties pay the CPA surcharge because it is tied to the property tax. There are a few situations where you may not see the surcharge or where you might qualify for relief.
Properties that do not pay
- Tax-exempt parcels: Properties that are fully exempt from property taxation do not receive a tax bill, so no CPA line appears. This can include certain municipal, state, charitable, religious, or educational properties.
- Publicly owned open space or conservation land: These are commonly tax-exempt and do not bear the surcharge.
Common local exemption pathways
Under M.G.L. c.44B, cities and towns can vote to adopt certain exemptions or abatements for the CPA surcharge. What is available in Sudbury depends on local adoption and current policy. Common options include:
- Low-income senior or low-income disabled homeowner exemptions: Many communities adopt relief for qualifying owner-occupants who meet age and income guidelines. Where adopted, this can reduce or eliminate the CPA surcharge for those households.
- Certain affordable housing properties: Deed-restricted affordable units, local housing authority properties, or qualifying nonprofit-owned housing may be treated differently. Some may already be tax-exempt, while others could have special treatment if that was part of local adoption.
Availability and details depend on local votes and administration. Exemptions are not automatic. If you think you qualify, you must apply.
Application and documentation
Exemption applications usually run through the Assessors’ Office. Expect to provide proof of ownership and occupancy, and for income-based programs you may need to submit documented income information. Deadlines matter. If you miss a filing window, you may have to wait until the next cycle. If you are uncertain, contact the Assessors’ Office early and ask which forms, deadlines, and documents apply to your situation.
What buyers and sellers should expect at closing
Because the CPA surcharge is part of the property tax levy, it is commonly prorated at closing just like property taxes.
Proration practice in a nutshell
Closing attorneys, escrow officers, and title companies typically prorate taxes using the most recent tax bill or a pro forma figure supplied by the Assessors. That proration includes the CPA surcharge unless your purchase agreement says otherwise. If the CPA rate changed recently, ask your closing team to verify the current figure.
Best practices for buyers and sellers
- Ask for the most recent tax bill early in the transaction, and look for the CPA line item.
- Confirm Sudbury’s current CPA percentage if the bill looks outdated or if you heard about a recent vote.
- Ask your closing attorney or title company how they handle CPA proration and whether they rely on a municipal pro rata figure.
- If you believe you qualify for a surcharge exemption, start the application process with the Assessors as soon as you take ownership and meet the criteria.
Budgeting: quick rule-of-thumb examples
The CPA surcharge is recurring. Build it into your annual operating budget. Use your most recent tax bill and the current CPA percentage to estimate.
Here are simple illustrations you can adapt:
- If annual property tax is $6,000:
- At a 1 percent CPA rate, the surcharge is $60 per year, about $5 per month.
- At a 3 percent CPA rate, the surcharge is $180 per year, about $15 per month.
- If annual property tax is $10,000:
- At a 1 percent CPA rate, the surcharge is $100 per year.
- At a 3 percent CPA rate, the surcharge is $300 per year.
Use your own tax amount and plug in Sudbury’s current CPA rate to get a precise estimate.

How Sudbury adopts rates and exemptions
