# Somerville Property Taxes in FY2026: What Rising Assessments Mean for Your Bill
Key Takeaways
•The rate barely moved: Somerville's FY2026 residential tax rate is $10.98 per $1,000 of assessed value, according to the City of Somerville Assessing Department.
•Your assessment is the real driver: If your home's assessed value rose, that increase — not the rate — is what pushes your bill higher.
•The bottom line: Under Proposition 2½, your bill tracks your home's value. Owner-occupants can cut it with the residential exemption (a discount for owners who live in their home).
•If your assessment looks too high: You can file an abatement (a formal request to lower your assessment). Confirm the current deadline and forms with the Somerville Assessing Department.
Why Did My FY2026 Somerville Tax Bill Feel Bigger?
If your bill felt heavier, your first thought may have been: "Did the city raise the tax rate?" Not really. Somerville's FY2026 residential rate was $10.98 per $1,000 of assessed value.

The bigger factor is usually your assessment — the city's estimate of your home's fair cash value. If the city said your home was worth more this year, your bill likely rose with it.
Is the Tax Rate Really the Problem?
Mostly no. The rate is the easy number to blame, but a small rate change adds only a modest amount to most bills.
There is also a state limit. Under Massachusetts' Proposition 2½, the city cannot raise its total property tax levy — the full amount it collects from property taxes — by more than 2.5% each year, plus allowances for new growth. So Somerville cannot simply raise the rate at will.
The city's assessing FAQ also states that elected officials cannot lower an individual assessment by request: "Can the Mayor or my Councilor get my assessment reduced? No. The law prohibits this."
Is My Assessment Driving the Increase?
Yes. Your tax bill follows a simple formula:
Assessed value × tax rate = tax bill
Because the levy is capped but individual assessments are not, the split between properties matters. A rate change moves most bills only slightly; a larger jump in your own assessed value moves your bill much more.
There is one silver lining: a higher assessment often reflects higher home value, and more equity if you own. But equity does not help when the bill is due — which is why exemptions matter. If you own and occupy your home, the residential exemption can cut thousands off the bill, so most owner-occupants pay meaningfully less than a raw value-times-rate estimate suggests.
Why Can My Bill Rise More Than 2.5%?
A common and fair question. Proposition 2½ limits the city's total tax levy. It does not cap the increase on every individual home.
So your bill can rise more than 2.5% if your home's assessment rises faster than other properties. In plain English: your share of the citywide tax pie got bigger. That is also why the citywide rate can shift while the total levy stays within its cap.
How Does Somerville Compare With the Rest of Massachusetts?
Somerville is not cheap by statewide standards. The Massachusetts Department of Revenue, Division of Local Services put the FY2026 average single-family tax bill at $8,113 and the average single-family value at $742,986.

Keep in mind this is not apples-to-apples. The state figure is a single-family average, while Somerville homes span all residential types. The comparison also cannot isolate how much of any gap is rate-driven versus assessment-driven.
What Should You Do If Your Assessment Looks Too High?
Start with the assessment, not the rate. If your value seems too high, confirm the current abatement deadline, required forms, and comparable-sales rules with the Somerville Assessing Department before the window closes. For future bills, keep the same playbook:
•Check your assessed value first, comparing it with similar homes that sold nearby.
•Pay the bill on time, and confirm how payment affects your appeal rights.
•Claim the residential exemption if you own and occupy the home.
•Review senior and other relief options if you may qualify.
The key point: Somerville's FY2026 rate barely moved — your assessment is what moves your bill. To know whether your home is fairly assessed, compare it against recent, similar Somerville sales before the next appeal window closes.
