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 Rockingham County, NH

Rockingham County’s effective property tax rate of 1.576% sits below New Hampshire’s statewide median of 1.782%, yet it ranks eighth among the state’s ten counties — a reminder that New Hampshire’s overall property tax levels are high enough that even a below-average county here pays far more than most places nationally. The national median rate is 0.794%, roughly half of what Rockingham property owners owe. On a median home value of $497,500, that rate yields an annual tax bill of $7,839, set against a median household income of $118,331 and per-capita income of $61,558. Communities such as Auburn, Candia, and Chester share this tax environment. The picture that emerges is a county that looks comparatively affordable within its own state but still carries a notably heavier property tax load than the country as a whole.

Frequently asked questions

What is the property tax rate in Rockingham County, NH?
The effective rate is 1.58% — meaning the median tax bill equals about 1.58% of the median home value.
How much are property taxes on a median home?
On the median home ($497,500), the estimated annual bill is about $7,839.
Is Rockingham 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 Rockingham 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 Rockingham County assessor within the local deadline, typically with comparable sales as evidence.
