Norfolk County, MA Property Tax: File With Your City or Town

If you own property in Quincy, Brookline, Weymouth, or any other Norfolk County city or town, your property tax appeal goes to your own municipality's Board of Assessors — not to "Norfolk County." Property assessment and abatements are a municipal function everywhere in Massachusetts, and that stays true in Norfolk County even though Norfolk is one of the few counties that never had its county government abolished. Miss your city or town's abatement filing deadline, which is tied to your actual (third-quarter) tax bill, and your next option is a state-level appeal to the Massachusetts Appellate Tax Board.

Why property taxes are set by your city or town — not Norfolk County

Massachusetts eliminated county government in many counties starting in the late 1990s (Worcester County's county government, for example, ended on July 1, 1998). Norfolk County is different: it still operates as a functioning county government, with an elected three-member County Commission and county-level offices including the Registry of Deeds, County Treasurer, courts, a correctional facility, and Norfolk County Agricultural High School, according to the county's official website.

None of that changes how your property tax bill gets set or appealed. The official Norfolk County government site lists its departments — Registry of Deeds, Treasurer, Engineering, Human Resources, Purchasing, the Agricultural High School — and property assessment or tax abatements are not among them. That's because under Massachusetts General Laws Chapter 59, assessing has always been a city and town responsibility statewide, regardless of whether a given county still has its own government. Norfolk County having a working Registry of Deeds and Sheriff doesn't give it any role in valuing your house or hearing your abatement — that authority sits entirely with your city or town's Board of Assessors.

How assessments work in Norfolk County's cities and towns

Every Massachusetts property is assessed based on its ownership and condition as of January 1 each year — Chapter 59, Section 11 ties the tax obligation to "the owner on January 1." Cities and towns then bill quarterly: two preliminary bills (roughly August and November) based on an estimate, followed by two "actual" bills (roughly February and May) once the new fiscal year's tax rate and your final assessed value are set.

Each municipality sets its own rate independently — there is no single "Norfolk County tax rate." For fiscal year 2026, for example, Quincy's assessors set a residential rate of $11.78 per $1,000 of assessed value and a commercial rate of $23.53 per $1,000, while Brookline set a residential rate of $10.24 per $1,000 and a commercial/industrial/personal-property rate of $17.16 per $1,000. Weymouth and Norfolk County's other cities and towns each set their own rate the same way, through their own local tax classification process — check your own city or town's assessors' office for the current figure rather than assuming a county-wide number.

Whether you should file an abatement

An abatement challenges your assessed value or classification, not the size of your tax bill on its own. It's usually worth filing if you can show your assessed value is higher than fair market value as of January 1 — for example, based on recent comparable sales of similar homes nearby — or if the assessors' record contains a factual error, such as wrong square footage, an incorrect number of bedrooms or bathrooms, or a listed feature (a garage, finished basement, extra bath) that doesn't exist. A high tax rate alone, or a bill that simply went up because your town's overall budget or rate changed, is not grounds for an abatement.

Step-by-step: how to file

1. Get your actual (third-quarter) tax bill. This is the bill that reflects your city or town's finalized rate and your assessed value for the fiscal year, and it carries the abatement deadline.
2. Confirm the deadline with your local Board of Assessors. Under Chapter 59, Section 59, an abatement application is due "on or before the last day for payment, without incurring interest... of the first installment of the actual tax bill" — in practice, this is the due date printed on your actual bill, commonly (but not universally) around February 1. Confirm the exact date with your own city or town, since it can shift if bills are mailed late.
3. Gather your evidence. Recent comparable sales, a recent appraisal, and photos or documentation of any factual errors in the assessors' property record card all strengthen an application.
4. File the abatement application with your city or town's Board of Assessors by the deadline — most Norfolk County assessors' offices offer both paper and online forms, and late applications generally cannot be accepted.
5. If denied (or not acted on), you can appeal to the Massachusetts Appellate Tax Board, a five-member board appointed by the governor within the state's executive Office of Administration and Finance. Under Chapter 59, Section 65, that appeal must be filed within three months of the assessors' decision, or within three months of the date the application is deemed denied.
6. Separately, check exemptions. If you're a senior, a veteran, legally blind, or facing financial hardship, Massachusetts law allows statewide exemption programs that are adopted and administered locally. These generally must be filed by April 1, or within three months of your bill or assessment notice going out, whichever is later.

Local tips

Because Norfolk County has no assessing office of its own, always start with your specific city or town. Quincy's Board of Assessors, for instance, can be reached at Quincy City Hall, 1305 Hancock Street, or by phone at (617) 376-1170, and posts current tax rates and exemption programs — including exemptions for residents 65+ and 70+, legally blind residents, disabled veterans, and surviving spouses or minor children of deceased public safety personnel — on its own assessors' website. Brookline publishes its current rates and abatement information through its own Assessors Division. Weymouth and Norfolk County's other municipalities each run a comparable local process; look up your own city or town's assessors' office rather than searching for a "Norfolk County assessor," since no such office exists for setting or appealing your tax bill.

Keep documentation of your property's condition as of January 1, since that's the legal valuation date regardless of any changes you make later in the year. And don't wait until the deadline is close — most assessors' offices will discuss your assessment informally before you file, which can resolve simple data errors faster than a formal abatement.
