What can change your bill?

The ACS effective rate is a ratio of medians, not a statutory rate. Local assessed values, levies, classification, caps and exemptions determine the actual bill.

Exemptions & assessment

No uniform flat exemption is applied. Enter your assessor-provided assessment ratio and qualifying exemption for a separate statutory scenario.

Payment dates & appeals

Towns and cities use their adopted billing schedule, including semiannual collection where authorized. Read the partial and final bills; a utility-tax deadline is not a homeowner property-tax deadline.

The state reference manual places the initial municipal abatement deadline at March 1 or 60 days after the final bill, whichever is later. A later BTLA or Superior Court appeal has a separate September deadline.

Check New Hampshire’s official property-tax guidance

Use an assessed value, exemption, and local millage

This separate scenario needs your assessor’s inputs. An exemption applies only to eligible levies; do not apply it to the county’s historical effective rate.

1 mill = $1 per $1,000 of taxable assessed value.

Good questions. Clear answers.

How much is property tax on a $400,000 home in New Hampshire?

The historical effective-rate estimate is $6,626 per year, or $552 a month. It multiplies $400,000 by 1.66%.

Is the effective rate the rate on my tax bill?

No. It is median real-estate taxes paid divided by median home value in the ACS 2020-2024 survey. Your taxing districts, assessed value, classification and exemptions determine your bill.

Can I subtract a homestead exemption from this estimate?

Use the separate statutory scenario with a qualifying levy. Subtracting an exemption from an ACS effective-rate estimate can double-count relief already reflected in taxes paid.

Does a higher purchase price change my assessment?

Assessment rules and reassessment dates vary by state and locality. Contact the linked official property-tax office before relying on a historical county ratio.

How do I appeal a property-tax assessment?

Read the deadline and procedure on your assessment notice, then use the official state guidance above to locate your assessor or review board. County survey data does not establish your appeal deadline.
