ZIP doesn't have ACS data — typically because it's a PO-box-only ZIP, a single-business ZIP, or a small area where the Census suppresses small-sample estimates. Try a nearby ZIP.

North Dakota's effective property-tax rate sits in the moderate range — around 0.99% of value statewide — and is set to ease further. The state taxes only a thin slice of a home's worth (residential taxable value works out to 4.5% of market), and the newly expanded Primary Residence Credit now knocks up to $1,600 off the bill on a main home, materially cutting effective bills going forward.

The explainer below covers the step-by-step taxable-value calculation, the annual February 1 assessment date, the Primary Residence Credit, and the Homestead and Disabled Veterans credits.
How North Dakota property tax works
North Dakota builds your taxable base in steps, which is why the rate looks low against market value. Local assessors first value property at true and full (market) value; assessed value is then set at 50% of that, and the taxable value is 9% of assessed value for residential property (10% for commercial). The two steps compound: residential taxable value comes out to just 4.5% of market value, so the Tax Commissioner's own example puts a $275,000 home at $12,375 of taxable value. Your county, city, school district, and any special districts each apply their mill rates to that taxable figure, and the combined levy is your bill. Property is reassessed annually as of February 1 at market value.
North Dakota's biggest homeowner break is the Primary Residence Credit. First created by HB 1158 in 2023 at $500, it was expanded by HB 1176 in 2025 to up to $1,600 per year, effective for the 2025 tax year (showing up on 2026 bills). There is no age or income limit — one credit per household — and owners apply between January 1 and April 1, 2026. The credit is subtracted directly from the property tax owed on a primary home.
Targeted relief is also available. The Homestead Credit for owners 65 and older or those permanently and totally disabled was widened by HB 1176: households at or below $50,000 of income get a 100% reduction (up to $11,250 of taxable value), those at or below $80,000 get 50%, and the renter refund cap rose from $400 to $600. Service-disabled veterans rated at least 50% can claim the Disabled Veterans Credit, worth up to 100% of the tax on the first $200,000 of true and full value ($9,000 taxable), scaled to the disability rating. On the policy side, HB 1176 (2025) is enacted, not proposed — it also added a 3% annual cap on the dollars a taxing district may levy without voter approval. (A separate 2024 ballot effort to abolish the property tax outright, Initiated Measure 4, failed at the polls.)
Why your actual bill differs
The numbers above describe a typical homeowner in this ZIP — not your specific bill. A few things move bills away from the median:
- Overlapping levies. Your bill stacks county, city, school-district, and special-district mill rates, so two similar homes in different districts can owe different amounts.
- The compressed taxable base. Because residential taxable value is only 4.5% of market, small differences in a home's market value and in local mill rates can swing a bill noticeably above or below the ZIP median.
- Credits. The Primary Residence Credit (up to $1,600 on a main home), the Homestead Credit for qualifying seniors and disabled owners, and the Disabled Veterans Credit each pull a qualifying owner's bill below the median.
North Dakota has no single statewide bill lookup — counties and cities run their own. Cass County's assessor and tax information is a working example; for other counties, search your county's assessor or treasurer site.
Methodology
Data on this page comes from the US Census American Community Survey 5-year estimates, 2020–2024 vintage (released January 29, 2026), at the ZIP Code Tabulation Area (ZCTA) level. After filtering ZCTAs the Census suppresses for privacy or small-sample reasons, this page covers 309 North Dakota ZIPs.
Topcoding in North Dakota. The Census caps median property tax at $10,000, reporting anything higher as $10,001. North Dakota's compressed taxable-value base keeps essentially every ZIP below the cap, so the figures here are true medians.

Frequently asked questions
Why is the median tax in my ZIP different from what I pay?
Median is the middle of the distribution, not your bill. North Dakota taxes only a thin slice of value — residential taxable value is 4.5% of market — then applies the combined mill rates of your overlapping county, city, school, and special-district levies. The Primary Residence, Homestead, and Disabled Veterans credits move qualifying owners further from the median.
Why might my ZIP show $10,001 as the median tax?
That's the Census topcode for privacy, but it's essentially absent in North Dakota — the compressed taxable base keeps medians under the $10,000 cap, so the figures here are true medians.
Where do I find my actual North Dakota property tax bill?
Through your county or city. North Dakota has no statewide portal; counties run their own. Cass County's assessor and tax page is a working example.
When does North Dakota data update on this page?
Annually, when the Census Bureau releases a new ACS 5-year vintage. The 2020–2024 vintage released January 29, 2026. The next vintage (2021–2025) typically follows the next year, though the Census has not yet posted its release date.
Why don't you cover other states yet?
State-by-state rollout. Each state needs its own context section (assessment method, exemptions, local taxing structure) to be genuinely useful. High-search-volume states are going live first.
