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 Sagadahoc County, ME

Sagadahoc County’s effective property tax rate of 1.041% lands almost exactly on Maine’s statewide median of 1.042%, effectively a tie with the middle of the state. Among Maine’s 16 counties, Sagadahoc ranks 10th, placing it in the lower-middle tier — below the state’s midpoint but not among its cheapest. Against the national median of 0.794%, however, the county’s rate runs noticeably higher, as is common across much of New England. On a median home value of $333,300, that rate yields an annual tax bill near $3,470, set against a median household income of $87,806 and per-capita income of $47,808. Topsham, the largest of the county’s principal communities, anchors a stretch of towns along the lower Kennebec. The takeaway: property taxes here track the state norm closely, while exceeding what most American homeowners pay.

Frequently asked questions

What is the property tax rate in Sagadahoc County, ME?
The effective rate is 1.04% — meaning the median tax bill equals about 1.04% of the median home value.
How much are property taxes on a median home?
On the median home ($333,300), the estimated annual bill is about $3,470.
Is Sagadahoc County's rate high or low?
Compare it to the state median of 1.04% 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 Sagadahoc 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 Sagadahoc County assessor within the local deadline, typically with comparable sales as evidence.
