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 Hillsborough County, NH

Hillsborough County’s effective property tax rate of 1.662% sits below New Hampshire’s statewide median of 1.782%, placing it seventh among the state’s ten counties. That ranking signals a middling position within a state known for high property taxes overall — Granite State rates run well above the national median of 0.794%, so even a below-average New Hampshire county like this one carries a heavier load than most American homeowners face. The median home value here is $421,100, yielding an annual tax bill of about $6,999. With median household income at $103,545 and per-capita income of $54,111, the county’s earnings help offset that bill. Manchester, the largest city in the county, anchors a tax landscape that is comparatively favorable by state standards but still steep by national ones.

Frequently asked questions

What is the property tax rate in Hillsborough County, NH?
The effective rate is 1.66% — meaning the median tax bill equals about 1.66% of the median home value.
How much are property taxes on a median home?
On the median home ($421,100), the estimated annual bill is about $6,999.
Is Hillsborough 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 Hillsborough 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 Hillsborough County assessor within the local deadline, typically with comparable sales as evidence.
