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 Carroll County, NH

At 0.989%, Carroll County's effective property tax rate sits well beneath New Hampshire's statewide median of 1.782%, yet it still edges past the national figure of 0.794%. That gap matters: even the lowest rate among New Hampshire's ten counties remains above what a majority of American homeowners pay. A median home value of $388,900 generates an annual tax bill of roughly $3,848, set against a median household income of $86,463 and per-capita income of $50,677. Communities such as Center Sandwich, North Sandwich, and Bartlett fall within this county, where the tax climate is gentler than the rest of the state but not quite aligned with national norms. Ranking last within New Hampshire signals that buyers here encounter the state's least aggressive property taxation, though the comparison with national figures tempers any impression of an outright bargain.

Frequently asked questions

What is the property tax rate in Carroll County, NH?
The effective rate is 0.99% — meaning the median tax bill equals about 0.99% of the median home value.
How much are property taxes on a median home?
On the median home ($388,900), the estimated annual bill is about $3,848.
Is Carroll County's rate high or low?
Compare it to the state median of 1.78% 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 Carroll 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 Carroll County assessor within the local deadline, typically with comparable sales as evidence.
