North Dakota Property Tax Calculator - Estimate your annual North Dakota property tax from true and full value, the 4.5% assessment ratio, and your local mill levy.

The North Dakota property tax calculator estimates the annual tax on a home or other real property using the same steps North Dakota counties follow. Instead of taxing a house at its full market price, North Dakota first reduces that value by a statewide assessment ratio and then multiplies the result by a mill levy set by local districts.

• • Budget before buying: Homebuyers model the annual tax on a purchase price so they know the true carrying cost before signing.
• • Check a county bill: Owners compare the estimate against the official statement to catch valuation or mill-rate errors early.
• • Plan a sale: Sellers see how the low assessment ratio affects net proceeds and the comparison with other states.

You enter your property's true and full value, the assessment ratio (4.5% for most homes), your mill levy, and any exemption. The tool returns your assessed value, taxable value, estimated annual tax, and effective rate so you can read the result the way the county presents it.

North Dakota is unusual because the taxable base is a small fraction of market value. That design choice is why the state's average effective rate stays near 1% even when local mill levies look large.

If you rent out part of the home, the rental property tax calculator shows how the same North Dakota assessment rules apply to income-producing real estate.

North Dakota multiplies true and full value by the assessment ratio to get assessed value, subtracts any exemption, and then multiplies the taxable value by the mill levy per $1,000.

• True & Full Value: The county assessor's market-value estimate that starts every North Dakota tax calculation.
• Assessment Ratio: The fraction assessed for tax; 4.5% for most residential property under NDCC § 57-02-02.
• Mill Levy: The combined rate set by local districts, expressed as mills per $1,000 of taxable value (1 mill = $1 per $1,000).

The mill levy is the part most owners misread. A mill is one dollar of tax for every $1,000 of taxable value, so a 250-mill levy means $250 of tax per $1,000 of taxable value, or 25% of the taxable base.

Because assessed value is only 4.5% of true and full value for most homes, the effective rate on market value is far smaller than the mill levy suggests. That gap between the mill levy and the effective rate is what the calculator makes explicit.

As described in the Property tax in the United States overview, North Dakota applies the local mill levy to the equalized assessed value, with mills expressed per $1,000 of taxable value

The Tax Foundation ranks North Dakota in the middle of states by average effective property tax rate, near 1.0% of home value.

Because North Dakota property tax can be deductible on Schedule A, the federal income tax calculator helps you see how the deduction affects your overall federal bill.

True and full value, the 4.5% assessment ratio, and the mill levy explain most of what appears on a North Dakota tax statement.

Reading a statement becomes easy once these four ideas click. The county shows true and full value and the assessment ratio, then lists a mill levy that combines into the single number you enter here.

The assessment ratio is the quiet driver of North Dakota's moderate ranking. Other states assess closer to market value, so their effective rates look higher at similar mill levies.

To see why North Dakota's 4.5% assessment ratio produces such a moderate effective rate, the property tax comparison by state ranks North Dakota against other states.

Gather your assessor's notice and tax statement, then enter each value exactly as printed to estimate your annual bill.

1. 1 Locate true and full value: it appears on the county assessor's valuation notice, usually near the top of the form.
2. 2 Confirm the assessment ratio: Use 4.5% for most residential property, or the class ratio the assessor lists for your property type.
3. 3 Enter the mill levy: Copy the combined mill levy from the county treasurer's tax statement, expressed as mills.
4. 4 Add any exemption: Enter the assessed-value reduction from an eligible exemption such as the homestead credit.
5. 5 Read the result: The tool shows assessed value, taxable value, estimated annual tax, and the effective rate as a share of true and full value.

A Burleigh County owner with a $250,000 true and full value, 4.5% ratio, and 280-mill levy enters those figures and sees a $3,150 estimate that matches the county statement.

Once you have an annual tax estimate, the mortgage calculator with taxes and insurance folds that figure into your full monthly housing payment.

Estimating your bill early helps you budget, spot valuation errors, and plan a home purchase or sale with realistic carrying costs.

• • Catch assessment errors: Compare your estimate against the county bill to surface mistakes in value or ratio before the appeal window closes.
• • Model mill changes: See how a higher or lower mill levy changes your annual cost before buying or before a local bond election.
• • See the true effective rate: Report the effective rate so you can compare North Dakota's burden against other states on equal footing.

An estimate is also a negotiating tool. A buyer who knows the real tax can weigh a low list price against a high district mill levy that raises the monthly cost.

Sellers benefit too, because the moderate effective rate is a genuine selling point that the calculator quantifies rather than asserts.

Pairing your property tax estimate with the North Dakota paycheck calculator lets you confirm that after-tax income covers both housing and living costs.

Your bill moves with true and full value, the assessment ratio, the local mill levy, and any exemption you claim.

• • The estimate excludes special assessments such as sewer, water, and bond elections not included in the general mill levy.
• • It does not replace the official county bill, which reflects final budgets and any late adjustments.

Two homes at the same market price can owe very different tax if they sit in different districts or different property classes.

Exemptions are the lever owners control directly, so confirming homestead-credit eligibility is worth the effort before filing.

According to North Dakota Century Code § 57-02-02, most North Dakota property is assessed at 4.5% of its true and full value, with other classes assessed at different statutory ratios

When a moderate assessment ratio boosts your home's appeal at resale, the capital gains tax calculator estimates the federal tax on the eventual sale.
