What you'll pay, at a glance

Property taxes are the largest local tax most homeowners pay. The effective rate measures the real tax bill as a share of home value — a more useful number than the nominal “mill rate,” because assessment practices vary county to county.

How this is calculated

The effective property tax rate is the median real-estate tax bill divided by the median home value — both for owner-occupied homes, from the U.S. Census Bureau's American Community Survey (ACS 5-year estimates)1. Median income is also from the ACS1. Federal and state income-tax figures use IRS2 and Tax Foundation3 data.

About Suffolk County, MA

The effective rate here is 0.659%, well under Massachusetts's statewide figure of 1.063% and also beneath the national median of 0.794%. That gap shows up in the annual tax: about $4,649 on a median-priced home. With a median household income of $95,631, the yearly levy amounts to roughly five percent of what a household earns. Boston, the county's largest city, anchors a market that also includes Dorchester and Roxbury. Among Massachusetts's 14 counties, Suffolk ranks 12th by property tax rate, so only two charge less. High purchase prices paired with a lower rate can suit buyers who expect to stay long enough to benefit from that lighter ongoing cost.

Frequently asked questions

What is the property tax rate in Suffolk County, MA?
The effective rate is 0.66% — meaning the median tax bill equals about 0.66% of the median home value.
How much are property taxes on a median home?
On the median home ($705,800), the estimated annual bill is about $4,649.
Is Suffolk County's rate high or low?
Compare it to the state median of 1.06% and the national average near 1.1%.
How does the effective rate differ from my mill rate?
A mill rate is the nominal levy per $1,000 of assessed value. The effective rate reflects what you actually pay after exemptions and assessments — it's the median tax bill as a share of median home value, so it better predicts your real cost.
Will a reassessment raise my tax bill?
Not necessarily. If your home's assessed value rises, your bill can go up, but only if the mill rate and exemptions stay flat. Contact the Suffolk County assessor's office to review your current assessment.
Can I appeal my property tax assessment?
Yes. Most counties allow an appeal when you believe the assessed value exceeds the market value. File with the Suffolk County assessor within the local deadline, typically with comparable sales as evidence.
