North Dakota has 53 counties, and property assessment is handled close to home. If you own a house in Grand Forks, a farm near Carrington or a storefront in Bowman, your value starts with a local office. In most counties that office is called Tax Equalization. This page lists 56 assessor offices across the state. The sections below explain what they do, who oversees them and how to get a clear answer from one.
The listings come from county and city offices. Some are staffed full time. Others share a courthouse with several county departments and keep limited hours. Knowing the difference saves you a wasted trip, especially where the nearest office is an hour's drive away.
How the Property Tax Cycle Runs in North Dakota
Property tax rules are set out in North Dakota Century Code Title 57. Property is assessed as of February 1 each year. The assessor estimates a true and full value, which is meant to reflect what the property would sell for in a normal market sale. The assessed value is 50 percent of that figure. Taxable value is then a smaller share of assessed value: 9 percent for residential property and 10 percent for commercial property.
Those layers confuse people, so keep one point in mind. The assessor sets value only. The assessor does not set the tax rate. Taxing districts such as the county, city, school district and park district adopt budgets, and those budgets become mill levies. The county auditor applies the levies to taxable value, and the county treasurer sends and collects the bill. When your bill rises, ask two questions. Did my value change, or did a levy change? Only the first question belongs at the assessor's counter.
Agricultural land is valued differently. In North Dakota, farmland is valued on its productivity and agricultural income, using soil data and a state-supplied formula, not on the latest sale price of a neighboring quarter section. That is why a rural office will talk about soil types and land classes rather than comparable sales.
Oil and gas production also sits outside the local property tax. It is taxed through state production and extraction taxes. Houses, shops, apartments and other improvements near well sites are still assessed locally.
Who Runs Assessor Offices in North Dakota
State law lets a county appoint a director of tax equalization, and many counties do. That is why so many entries here read Tax Equalization rather than Assessor. The director's office values property in the townships and smaller cities, and often in the county seat too. Larger cities may keep their own assessor. Wahpeton, for example, lists a City Assessor at 1900 4th Street North, phone 701-642-8449, inside Richland County.
Above the local level sits the Office of State Tax Commissioner and its property tax division. The Tax Commissioner supervises assessment practice statewide, issues forms and guidance, and runs the training and certification that assessors rely on. The office also assesses centrally valued property, such as pipelines, railroads and utilities. These cross many counties and cannot be valued by one local office.
Boards of equalization are the formal appeal path. Township and city boards meet in the spring, usually April. The county commission then sits as the county board of equalization, typically in June. Those meetings are your best chance to challenge a value. After they close, relief is limited and usually comes through an abatement request to the county commission, which has strict deadlines. Confirm the dates with your county each year, because they can shift.
Rural Counties, Oil Country and College Towns: How North Dakota Offices Differ
The state's population is small and spread out, and staffing reflects that. Cass County Tax Equalization, at 211 9th Street South in Fargo (701-241-5616), serves the largest city in the state and its suburbs, with a deep parcel base and more specialized staff. In Grand Forks County, the office at 151 South 4th Street (701-780-8201) deals with a university city, steady new construction and farmland in the same county. Burleigh County, which covers Bismarck, lists PO Box 5518 and phone 701-222-6693, so call before you plan a visit.
Western North Dakota is a different story. McKenzie County has seen oil-driven growth, and its office at 201 5th Street Northwest in Watford City (701-444-6852) handles the new housing and commercial buildings that came with it. Our records carry that listing under the name Mcintosh County Tax Equalization, so confirm which county's records it holds before you visit.
Farther south and west are quiet ranching counties. Slope County has one small office at 206 Main Street in Amidon (701-879-6370). Golden Valley County works from Beach (701-872-4673). Bowman County is at 104 1st Street Northwest in Bowman (701-523-3129). In offices this small, one person may handle valuation, records and questions from the public.
In the north and east, farmland dominates the rolls. Ramsey County has its office at 524 4th Avenue Northeast in Devils Lake (701-662-7012). Bottineau County is at 314 5th Street West (701-228-2901). Towner County is at 315 2nd Street in Cando (701-968-4352). Burke County uses PO Box 174 in Bowbells (701-377-2661), and Foster County uses PO Box 257 in Carrington (701-652-3060).
Several offices list only a post office box. A box is for mail, not walk-in visits. Phone the courthouse for the street address and public hours before you drive.
What to Bring and When to Go in North Dakota
A short, prepared visit gets better results than a long, open-ended one. Bring what the office needs to find your parcel and judge your case:
- Your parcel number or legal description, found on your tax statement.
- The tax statement or valuation notice you are questioning.
- Photos and dates for any renovation, fire, flood damage or demolition.
- A recent appraisal, closing statement or sales you consider comparable.
- For farmland, a field map, soil information and notes on any change in use.
Timing matters. Valuation work wraps up in the spring, ahead of the April and June board meetings, so that is when questions are most useful. Early calls also leave time to fix a simple error, such as the wrong square footage or a building that no longer exists, before a board ever needs to hear it.
Ask about credits at the same visit. The Tax Commissioner administers the Homestead Credit for qualifying seniors and people with disabilities, and income limits apply. The county office can tell you where to file. Other credits exist for some disabled veterans, and the rules change from time to time, so check current requirements.
Finally, remember that an assessor explains how a value was reached. That is a different job from setting your levy or collecting your bill. Bring tax-rate questions to the county auditor, and payment questions to the county treasurer. Sending each question to the right desk saves time for you and for the staff.
Property assessor offices in North Dakota operate under state property tax statutes that specify how properties must be valued, how often reappraisals occur, and what exemptions are available to qualifying homeowners. The state department of revenue or taxation typically provides oversight and technical guidance to county assessors to ensure consistent valuation practices statewide.
Assessor locations are available in 52 cities across North Dakota. They are spread across 52 counties.
Cities with the highest concentration include Devils Lake, Wahpeton, Watford, where high real estate activity and complex commercial properties create greater demand for assessor services and property valuation resources.
Property owners in North Dakota should verify that their primary residence homestead exemption is active and confirm the annual appeal deadline with their local assessor office, as missing the deadline means waiting until the following tax year to contest a valuation.

Finding the Right Assessor Office in North Dakota Counties
County seats here are small, and the assessor's office is usually inside or beside the courthouse. Stark County Tax Equalization sits at 51 3rd Street East in Dickinson, phone 701-456-7671, and serves the hub of the southwest. In the Red River Valley, Walsh County's office is at 600 Cooper Avenue in Grafton, and Pembina County's is at 301 Dakota Street West in Cavalier, phone 701-265-4697. Adams County Tax Equalization is at 602 Adams Avenue in Hettinger, phone 701-567-2990. The Sioux County office is at 302 2nd Avenue in Fort Yates, phone 701-854-3481.
Property records are public in North Dakota. You can usually ask to see the property record card for a parcel, which shows land size, building details and valuation history. Many counties publish this data online, but not all do, so call if you cannot find it. Having both a parcel number and an address speeds up the search.
Part of the state is tribal land. Fort Yates sits within the Standing Rock Reservation, and the ownership status of a parcel can affect whether and how it is taxed. If your land is held in trust, ask the office before you assume a bill applies.
Keep notes on every call: the date, the person you spoke with and what they said. If a dispute reaches a board, those notes carry weight.
