Hampshire County property tax: the real numbers
Property tax is the most local tax there is. Two homes of the same value in different counties – sometimes in different towns of the same county – can carry very different bills, because the rate is the sum of every overlapping district that taxes you: the county, the town or city, the school district, and often fire, library or water districts on top. So the hampshire county property tax figure below is an average across the whole county – your own bill depends on which districts you sit inside.
| Figure | Hampshire County | National |
|---|---|---|
| Median annual property tax bill | $5,589 | $4,271 |
| Effective property tax rate | 1.36% | about 0.90% |
| Median home value | $390,300 | – |
Source: U.S. Census Bureau American Community Survey (5-year), the same dataset the Tax Foundation uses. The effective rate is total real-estate taxes paid divided by total owner-occupied home value – so it reflects what people actually pay, not the headline millage rate.
Who actually sets your hampshire county property tax value
This is the part most guides get wrong. In Massachusetts, your city, town or township sets your assessed value – not Hampshire County. If you ring the county about your assessment, you are ringing an office that did not set it. Start with your local assessor. The county still matters for the appeal itself, which is covered below.
Worth knowing about Hampshire County:
In Massachusetts the TOWN/TOWNSHIP assesses; the county does not. The generator must say so.
How often your hampshire county property tax value is reassessed:
Each of 351 cities/towns (no county property tax) values property at 100% full and fair cash value as of January 1, with the state DOR certifying values at least every few years. Proposition 2 1/2 caps how much a community’s total tax levy can grow (2.5% a year plus new growth) – a levy cap, not a cap on your individual assessment.
How to appeal your hampshire county property tax assessment
⚠ The deadline — miss it and you usually wait a full year
The due date of your FIRST ACTUAL tax bill – usually February 1
IMPORTANT – IN MASSACHUSETTS YOUR TOWN OR TOWNSHIP ASSESSES, NOT THE COUNTY. Hampshire County does not set your value. Find your local assessor and start there. Massachusetts calls it an ‘abatement.’ File an Application for Abatement (State Tax Form 128) with your local Board of Assessors by the due date of the first ACTUAL tax bill (usually February 1). The assessors have three months to act (no answer = ‘deemed denied’); then appeal to the state Appellate Tax Board within three months.
Pay the tax as billed to protect your rights.
Almost every hampshire county property tax appeal comes down to one claim: the assessor thinks my home is worth more than it really is. Everything below is about proving that.
Do this first, before you file anything: ask for your property record card and read it. A surprising share of assessments are simply wrong on the facts – the wrong square footage, a bathroom you do not have, a finished basement that is bare concrete, a garage that was torn down. Factual errors are the easiest appeals to win, because there is nothing to argue about.
Then build the one thing that actually wins appeals: comparable sales. Find three to five homes near you, as similar as you can get on size, age, and condition, that sold recently for less than your assessed value. Not listings – sales. Not Zillow estimates – recorded sales. Boards ignore opinions and respond to comps.
A successful hampshire county property tax appeal does not change your tax rate – it lowers the value the rate is applied to, which lowers the bill for as long as the new value stands.

Appeals are heard by the Local Board of Assessors (abatement), then the Appellate Tax Board. In most places there is a free, informal step first – a conversation or a paper review with the assessor – and it resolves a large share of cases without a hearing. Take it. It costs you nothing and it is the fastest way to win.
One honest warning: an appeal reviews your value, and a review can go up as well as down. That is uncommon when you bring real comparable sales, and it is exactly why you check your comps before you file.
Where to go: find your office through Massachusetts DOR, Division of Local Services, which lists the assessing office for every county in Massachusetts.
Hampshire County property tax exemptions you may qualify for
This is where most homeowners quietly overpay their hampshire county property tax. Exemptions are almost never applied automatically – you have to claim them, and many people simply never do. It is worth ten minutes of your time to check.
HOMESTEAD: Where adopted, up to 35% of average residential value (Boston ~$350,000 off; ~$3,600 savings). Confirm with your city/town assessor. | SENIOR: Clause 41C ~$1,000+ off tax (local); state circuit-breaker credit up to ~$2,730 (income limit about $64,000 single). Confirm with your assessor / MA DOR. | VETERAN: $400-$1,500+ by rating, up to a full exemption at 100%. Confirm with your city/town assessor. | DISABILITY: Blind (Clause 37A) $500+ off tax; hardship varies. Confirm with your city/town assessor.
Homestead: Massachusetts has no statewide homestead exemption, but many cities (Boston, Cambridge, Somerville, Worcester, and others) adopt a local-option Residential Exemption that cuts the taxable value of owner-occupied homes by up to 35% of the average residential value – a very large benefit where offered (Boston removes roughly $350,000 of value). File annually with your local assessor (Boston uses Form RES) by about April 1.
Senior / over-65: Seniors have several ‘clause’ options: Clause 41C/41C½ knocks $1,000+ off the tax for owners 65+/70+ with income and asset limits (towns can enhance it); Clause 41A lets 65+ owners DEFER taxes (lien, ~6-8% interest). Separately, the state Senior Circuit Breaker (an income-tax credit, Schedule CB) refunds property tax above 10% of income – up to about $2,730 – for owners 65+ under the income limit.
Veteran: Veterans exemptions (MGL c. 59 sec. 5, Clause 22 series): reduce the tax by $400 up to $1,500+ based on VA disability rating; a veteran who is 100% disabled (or certain paraplegic/specially-adapted-housing cases) can be fully exempt. Surviving spouses and Gold Star families qualify. Apply with your local assessor.
Disability: Blind residents get a Clause 37A exemption ($500+ off the tax, with annual certification), and a Clause 18 hardship exemption is available at the assessors’ discretion. Disabled seniors can also use the state Senior Circuit Breaker credit. Apply with your local assessor.
Common questions about hampshire county property tax
Why did my hampshire county property tax bill go up when I did nothing to the house?
Two different things can raise a bill: your assessed value went up, or a taxing district raised its rate. They are separate, and only the first one can be appealed. Your notice will show which changed.
Do I call Hampshire County about my assessment?
No. In this state the county does not set your value – your city, town or township assessor does. Start there.
Is it worth appealing my hampshire county property tax?
Ask one question: would a similar home near mine sell for less than the value the assessor has put on mine? If yes, you have a case, it is usually free to file, and in many places the informal review settles it without a hearing.
Do I need to hire someone to appeal?
No. The informal review and the local board are built for ordinary homeowners to use themselves, and there is normally no fee. Appeal services exist and can be worth it for some people, but you are not required to use one and you should never be told you are.
How is my hampshire county property tax bill actually calculated?
Your assessed value is multiplied by the combined rate of every district that taxes you, then any exemptions you have claimed are subtracted. That is why two neighbours can pay different amounts on identical homes – one of them claimed an exemption the other never did.
