What Is the New Hampshire Property Tax Calculator?
The New Hampshire Property Tax Calculator estimates the annual property tax on a Granite State home or building from its full market value, the property class, and the local tax rate. New Hampshire raises most of its local government, school, and county revenue through property tax because it charges no general sales tax and no tax on wages, so the property bill is often the single largest tax a New Hampshire household pays. This tool takes the market value you enter, applies the statutory assessment ratio for the chosen property class, and multiplies the resulting assessed value by your town's tax rate per $1,000.
- • Estimate before you buy: Model the annual bill on a purchase price so you know the true carrying cost before signing.
- • Compare towns: Swap only the tax rate to see how much the same home costs across neighboring communities.
- • Test an exemption: Quantify the dollar saving from an elderly, disabled, blind, veteran, or homestead credit you may qualify for.
You enter the full market value, pick the property class, add your town's rate in dollars per $1,000 of assessed value, and list any exemptions. The tool returns assessed value, annual tax, monthly tax, and the effective rate against market value so the result reads the way New Hampshire presents it.
New Hampshire's rate is unusual because it is printed per $1,000 of assessed value, not as a percent of market price, and the assessed base is only a fraction of market value. The calculator handles both conversions so the bill matches the town statement.

How the New Hampshire Property Tax Calculator Works
The New Hampshire Property Tax Calculator runs New Hampshire's classified system rather than taxing property at full value: build the assessed value from the class ratio, subtract exemptions, then apply the local rate per $1,000.
- Market Value: The full market (fair cash) value that starts every New Hampshire tax calculation.
- Class Assessment Ratio: The statutory share of market value assessed for tax: about 4.5% residential, 10.5% apartments, 12.5% commercial, 15% industrial under RSA 75:1.
- Tax Rate per $1,000: The combined town, county, school, and state rate expressed per $1,000 of assessed value.
$400,000 residential home at $20 per $1,000
Market value $400,000, residential ratio 4.5%, town rate $20 per $1,000, no exemption.
Assessed value = 400,000 x 0.045 = $18,000. Tax = 18,000 x (20 / 1,000) = $360.
Estimated annual tax = $360; monthly = $30; effective rate = 360 / 400,000 = 0.090% of market value.
The effective rate looks tiny because only 4.5% of the value is assessed.
According to NH Department of Revenue Administration - Municipal Tax Rates, New Hampshire municipalities assess property by class at statutory ratios and levy tax in dollars per $1,000 of net assessed value.
According to the New Hampshire Department of Revenue Administration property tax overview, New Hampshire law (RSA 75:1) sets different assessment ratios for residential, apartment, commercial, and industrial property.
If you own a rented building, the rental property tax calculator applies the same New Hampshire ratios to income-producing property.
Key New Hampshire Property Tax Concepts
Four ideas explain why a New Hampshire tax bill looks different from a simple percentage of home price.
Market Value
The estimated price the property would fetch on the open market. It is the starting point for every New Hampshire tax calculation and the number you challenge if you believe the town overvalued the home.
Class Assessment Ratio
The statutory share of market value New Hampshire assesses for tax. Residential is about 4.5%, apartments 10.5%, commercial 12.5%, and industrial 15% under RSA 75:1. Only the assessed value, not the full price, is taxed.
Tax Rate per $1,000
The combined town, county, school, and state rate expressed in dollars per $1,000 of assessed value. A rate of $20 means $20 of tax for every $1,000 of assessed value; dividing by 1,000 turns it into the decimal used in the formula.
Exemptions and Credits
New Hampshire allows dollar exemptions that lower assessed value before the rate is applied: credits for elderly, disabled, blind, and certain veteran homeowners, plus homestead-type relief. Because they cut assessed value directly, a $2,000 exemption can reduce the bill by more than $2,000 in a high-rate town.

How to Use This Calculator
Four inputs produce a complete estimate; gather them from the town assessment record and your tax bill.
- 1 Find market value: Use a recent sale price, appraisal, or the town's assessment record.
- 2 Pick the property class: Choose residential, apartments, commercial, or industrial so the correct statutory ratio is applied.
- 3 Enter the town rate: Copy the combined rate in dollars per $1,000 of assessed value from your tax bill or the NHDRA municipal rates report.
- 4 Add exemptions: Enter the dollar total of any elderly, disabled, blind, veteran, or homestead credit you qualify for.
- 5 Read the result: The tool shows assessed value, annual tax, monthly tax, and the effective rate against market value.
A buyer comparing two towns for a $350,000 home enters $350,000 as residential, then tries a rate of $18 in Town A and $28 in Town B. Town A yields about $283 a year and Town B about $441, a $158 annual gap that shows how much the town rate drives the New Hampshire bill.
The Alabama property tax calculator works the same way for a state that uses a flat 10% residential ratio, useful when relocating.
Benefits of Using This Calculator
The New Hampshire Property Tax Calculator turns town jargon into numbers you can act on before money changes hands.
- • Plan housing cost: Budget monthly and annual cost before committing to a purchase, since New Hampshire has no sales or wage tax to offset a high property bill.
- • Compare towns directly: Swap only the tax rate to see whether a higher-priced home in a lower-rate town actually costs less.
- • See the true effective rate: Report the effective rate so you can compare New Hampshire's low-ratio system with flat-ratio states on equal footing.
- • Quantify exemptions: Confirm how much an elderly, disabled, blind, veteran, or homestead credit actually saves you each year.

Factors That Affect Your Results
The New Hampshire Property Tax Calculator isolates three variables that move the result more than any other input.
Town Tax Rate
The statewide average is about $19.90 per $1,000 of assessed value, the highest average in the nation, but individual towns range from roughly $12 to over $34 per $1,000, so the same home can owe very different amounts a few miles apart.
Property Class
The class sets the assessment ratio, and that ratio quietly changes the effective rate even when the dollar rate per $1,000 looks similar. Commercial and industrial classes are assessed at two to three times the residential share.
Exemptions and Credits
They lower assessed value directly, so the saving equals the exemption times the rate per $1,000, which can exceed the exemption amount in high-rate towns.
- • Estimates only; the official tax bill and the town's equalized assessment control what you actually owe.
- • You must supply the current local tax rate; the tool does not fetch it by town.
- • It does not model every special district, bond, or the separate education tax overlay some towns levy.
According to Tax Foundation - Property Taxes by State, New Hampshire relies heavily on property tax and ranks among the highest average property tax burdens in the country.
The statewide average municipal tax rate is about $19.90 per $1,000 of assessed value (see the New Hampshire Department of Revenue Administration municipal tax rates tables), the highest average in the nation.

Frequently Asked Questions
Q: How is New Hampshire property tax calculated?
A: New Hampshire finds the assessed value as the market value times the statutory assessment ratio for the property class, subtracts any exemptions, then multiplies by the local tax rate in dollars per $1,000 of assessed value. For a residential home, the ratio is about 4.5%, so a $400,000 house is assessed near $18,000 before the rate is applied.
Q: What is the New Hampshire residential assessment ratio?
A: Residential property is assessed at about 4.5% of market value under New Hampshire's classified system. Apartments are assessed near 10.5%, commercial near 12.5%, and industrial near 15%. The ratio converts full market value into the smaller assessed value that the tax rate is applied to.
Q: What is the New Hampshire property tax rate per $1,000?
A: Towns state the rate in dollars per $1,000 of assessed value. The statewide average is about $19.90 per $1,000, the highest average in the country, but individual towns range from roughly $12 to over $34. Because the residential assessment ratio is low, this high-looking rate produces a small effective rate against the sale price.
Q: Why are New Hampshire property taxes so high?
A: New Hampshire has no general sales tax and no tax on wages, so cities and towns rely on property tax for schools, roads, and county services. The dollar rate per $1,000 is high to raise that revenue, although the low residential assessment ratio keeps the effective rate against market value modest compared with the rate number alone.
Q: What is the difference between assessed value and market value in New Hampshire?
A: Market value is the estimated sale price. Assessed value is the smaller base the tax is computed on, equal to market value times the class assessment ratio minus exemptions. A $400,000 home is typically assessed near $18,000 on the residential ratio, which is why the tax bill looks small next to the home's price.
Q: Are there property tax exemptions or credits in New Hampshire?
A: Yes. New Hampshire allows dollar exemptions for elderly, disabled, blind, and certain veteran homeowners, plus homestead-type relief in some cases. They reduce assessed value before the rate is applied, so the savings equal the exemption times the tax rate per $1,000, which can exceed the exemption amount in high-rate towns.
