Property taxes in North Dakota are assessed and collected at the local level — primarily by counties and municipalities — with rates varying significantly depending on where your home is located. The statewide average effective rate for 2025is 0.98%, meaning a homeowner with a $253,100 median-value home typically pays around $2,480 per year in property taxes. For a monthly perspective, that works out to roughly $207/month — a line item that should factor into every home purchase decision in North Dakota.
North Dakota uses a 9.0% assessment ratio for primary residential properties. This means the county assessor sets your home's taxable (assessed) value at 900% of its market value. On a $400,000 home, for example, the taxable assessed value would be $36,000. Mill rates (the nominal tax rate per $1,000 of assessed value) are then applied to this lower figure.
Available Exemptions in North Dakota
Homestead Tax Credit: for seniors 65+ or disabled — credit varies based on income (up to $9,000 for the lowest income bracket). Equivalent to roughly $66,667 market value reduction.
Homestead Credit for seniors 65+ or disabled persons with income under $42,000: property tax credit of $500–$4,500 depending on income tier.
100% service-connected disabled veterans: $10,000 off assessed value (~$111K market equivalent at 9% ratio). Less disabled: proportional reductions.
What Makes North Dakota's Property Tax System Unique
North Dakota uses a 9% residential assessment ratio, one of the lowest in the country, which keeps nominal rates high but effective rates moderate. Oil boom counties (Williams, McKenzie) have fluctuating tax bases. Cass County (Fargo) is the most populous.
When Are North Dakota Property Taxes Due?
North Dakota property taxes are paid on a semi-annual (twice per year) basis. Due dates: February 15 and October 15. Missing a due date typically results in penalty interest (often 1–2% per month) and eventually tax liens, so it is important to calendar these dates well in advance — especially if you have a mortgage and your lender handles property tax through escrow (in which case they pay on your behalf from your escrow account).
How to Appeal Your Property Tax Assessment in North Dakota
If you believe your property has been over-assessed — which is surprisingly common, especially after rapid market changes — you have the right to appeal. File with your county Board of Equalization by April 15. Further appeals go to the State Board of Equalization.
To build a strong appeal, gather comparable sales (homes similar in size, age, and condition that sold recently for less than your assessed value), photos documenting property defects, and any independent appraisals you have. Many homeowners who appeal see their assessments reduced — and some jurisdictions allow free informal hearings before a formal appeal is required.

Pro Tips for North Dakota Property Owners
- Apply for every exemption you qualify for — many homeowners leave money on the table by not filing for the homestead or senior exemption. Applications are typically annual or one-time, and deadlines are firm.
- Review your assessment notice every year. If the county's estimate of your home's market value seems too high relative to what similar homes are actually selling for, appeal it. Even a 10% reduction on a $400,000 assessment saves $400–$700/year at typical North Dakota rates.
- If you have a mortgage, confirm with your lender whether property taxes are paid via an escrow account. If so, ensure your escrow balance is adequate — under-funded escrow leads to an escrow shortage and a sudden increase in your monthly mortgage payment.
- Pay early if your state offers discounts. Some states (like Florida) give 1–4% discounts for early payment. On a $5,000 tax bill, a 4% early-payment discount saves $200 — for essentially zero work.
- Property taxes are generally deductible on your federal income tax return as part of the SALT deduction (state and local taxes), subject to the $10,000 cap introduced by the Tax Cuts and Jobs Act. For high-tax states, this cap is often a binding constraint.
