North Dakota Business Property Tax: Personal Property Is Exempt, Real Property Assessed at 50%, 5% Discount by Feb 15

If you are forming a business in North Dakota, you may hear that you will owe a business personal property tax on your equipment, furniture and inventory. For most businesses, that is not how the system works. Under North Dakota law, personal property is exempt from property tax unless it falls into one of a few listed cases. The property tax that reaches most business owners is on real property, meaning the land and buildings you own or lease in a way that makes you the taxpayer of record.

This guide explains what is taxed, how the taxable value is calculated, the dates that matter, and what to confirm with your county before you budget for property tax. It is a practical starting point, not a substitute for advice from a qualified professional.

Informational content only. This article is not legal, tax or accounting advice. North Dakota rules can change, and the answer for your property depends on facts this guide cannot see. Confirm current requirements with your county, the Office of State Tax Commissioner and the Secretary of State. For complex situations, such as property in several counties, real estate held inside an entity, or assets that may fall under an exception, talk with a North Dakota attorney or a CPA.

Personal Property Is Exempt, With Three Exceptions

North Dakota Century Code 57-02-08(25) exempts personal property from property tax. That means movable business property such as office furniture, computers, shop tools and inventory is generally not on the property tax roll. The exemption does not apply in three situations:

Property of entities assessed by the State Board of Equalization.
Property taxed in lieu of property tax.
Property taxed under another law.

Whether a specific asset fits one of these exceptions is a fact-specific question. Do not assume either answer. If you are unsure how an asset is treated, ask your county in writing and keep the response with your business records.

Because the default rule is exemption, most small businesses should focus their property tax planning on real property rather than on the equipment they use every day.

What North Dakota Does Tax

The categories that remain on the property tax roll are:

Real property. This includes land and buildings, along with the heating, cooling and plumbing systems that are part of the building. Removable trade machinery is not treated as part of the building, so it does not fall into the real property base.
Mobile homes that are 27 feet or longer or that sit on utilities.
Centrally assessed property, including railroads, utilities, pipelines and airlines.

Telecommunications companies pay a 2.5% gross receipts tax in lieu of property tax, so they follow a separate track from a typical commercial owner.

For most readers, the practical question is whether the building or land they own, or the building they are buying, is on the real property roll. If it is, the valuation rules below control the bill.

How Real Property Is Valued

Real property tax is calculated in three steps:

True and full value. This is the market value of the property (NDCC 57-02-01).
Assessed value. Assessed value is 50% of true and full value.
Taxable valuation. For commercial and centrally assessed property, taxable valuation is 10% of assessed value. For residential property, it is 9%.

The result is that a commercial building is taxed on about 5% of its market value. The table below uses a hypothetical $1,000,000 commercial building to show the steps.

Step	Calculation	Result
True and full (market) value	Assumed for this example	$1,000,000
Assessed value	50% of market value	$500,000
Taxable valuation (commercial)	10% of assessed value	$50,000
Property tax	Taxable valuation multiplied by the total mill levy for the parcel	Depends on location

A mill is one dollar of tax for every $1,000 of taxable valuation, so the final bill depends on the total mill levy that applies to your parcel. Each taxing district sets its own levy, which means the rate depends on where the property sits. North Dakota does not publish a single statewide property tax rate. Counties assess and collect the tax, and your county can tell you the total levy for your parcel.

Key Dates for Real Property Tax

The calendar is short, and the deadlines are where owners lose money. Keep these dates on your business calendar:

Date	What Happens
January 1	Taxes are due.
February 15	If the full real estate tax is paid by this date, a 5% discount applies (NDCC 57-20-09).
After March 1	The first installment of real estate tax becomes delinquent. A 3% penalty applies, and later dates carry additional penalties.
After October 15	The second installment of real estate tax becomes delinquent.

The February 15 discount is worth planning for. On a hypothetical $10,000 real estate tax bill, paying the full amount by February 15 would reduce the payment by $500. Whether early payment makes sense depends on your cash flow, your borrowing costs and how much you expect to owe. Confirm how the installments are split and how penalties are calculated with your county before you rely on a specific schedule.

Other Business Charges to Plan For

Property tax is one line in a broader cost picture. North Dakota does not have a franchise tax, and it does not issue a general statewide business license. Other charges that new owners commonly face include:

Sales and use tax. The state rate is 5%, plus city and county taxes. Any business making taxable sales must hold a sales and use tax permit from the Office of State Tax Commissioner, applied for through ND TAP about 30 days before opening.
Limited liability company annual report. The fee is $50 and is due November 15 each year for business LLCs. Farming or ranching LLCs are due April 15 instead.
Corporation annual report. The fee is $25 and is due August 1 each year for domestic corporations.
Contractor license. If you do construction work and the cost, value or price of a job exceeds $4,000, you must hold a North Dakota contractor license issued by the Secretary of State. Licenses renew annually by March 1.

North Dakota licenses by activity, not by general business. If your business is not in one of these categories, you may still need a license from a state board or agency that covers your trade. Confirm that with the relevant agency before you open.

Steps to Take Before Your First Tax Year

Sort your assets. Separate real property (land, buildings and the built-in systems that are part of them) from everything else.
Get your assessment information. Ask your county for the true and full value, assessed value and taxable valuation for each parcel you own.
Confirm the mill levy. Ask your county for the total levy that applies to each parcel, since levies are set by each taxing district.
Calendar February 15. Decide in advance whether paying the full real estate tax early is a good use of cash.
Get unusual assets in writing. For trade machinery attached to a building, mobile homes or property connected to a regulated utility, ask the county how the asset is treated and keep the answer on file.
Have a CPA review your books. Ask a CPA to confirm how property is recorded and reported on your tax return, particularly if you hold real estate inside an LLC or corporation.

Where to Confirm Current Requirements

Rules, fees and deadlines can change. Verify anything that affects your budget with the agency that administers it:

Office of State Tax Commissioner: https://www.tax.nd.gov/
Sales and use tax permit application through ND TAP: https://tap.tax.nd.gov/?Link=Application
North Dakota Secretary of State: https://www.sos.nd.gov/
North Dakota Small Business Development Centers, hosted by the University of North Dakota Nistler College of Business and Public Administration: https://und.edu/ndsbdc/index.html
Your county: North Dakota has 53 counties, and each county assesses and collects property tax for the parcels within it.

For most small businesses, the good news is that personal property is exempt, which keeps the property tax conversation focused on real property. The three things to get right are the valuation chain from market value to taxable valuation, the mill levy for your parcel, and the February 15 discount deadline. Confirm each with your county, and bring a CPA or attorney in when the facts get complicated.
