If you sell taxable goods or services in North Dakota, you must obtain a sales tax permit from the Office of State Tax Commissioner before your first sale. The North Dakota sales tax registration requirements apply to any business with a physical presence in the state and to remote sellers whose taxable sales into North Dakota exceed $100,000 in the current or prior calendar year.1North Dakota Office of State Tax Commissioner.

Who Has to Register
State law prohibits anyone from operating as a retailer in North Dakota without first obtaining a sales tax permit.3North Dakota Legislative Branch. North Dakota Century Code 57-39.2 – Sales Tax – Section 57-39.2-14 Two kinds of connection to the state trigger that obligation.
The first is physical presence. If your business keeps a storefront, warehouse, office, inventory, or employees in North Dakota, you have physical nexus and must register regardless of your sales volume. There is no minimum dollar amount and no grace period beyond the recommended 30-day lead time for applying.
The second is economic nexus. If you have no physical presence but your taxable sales into North Dakota exceed $100,000 in the current or prior calendar year, you must register.1North Dakota Office of State Tax Commissioner. Marketplace Facilitator The first time you cross the threshold, you have 60 days to begin collecting tax, or you must start on January 1 of the following year, whichever comes first.
North Dakota does not use a separate transaction-count test. The $100,000 figure is the sole economic nexus trigger. Only taxable receipts count toward it; nontaxable and exempt sales are excluded.
Selling Through a Marketplace
If your only sales into North Dakota happen through a marketplace like Amazon, Etsy, or Walmart.com, the marketplace facilitator is generally responsible for collecting and remitting the tax. A qualifying marketplace facilitator that exceeds the $100,000 threshold must obtain its own permit and handle sales tax for all sales it facilitates.4North Dakota Legislative Branch. North Dakota Century Code 57-39.2 – Sales Tax – Section 57-39.2-02.3 The facilitator certifies to its sellers that it will collect, and sellers who accept that certification in good faith can leave those sales off their own returns.
That does not always end your registration obligation. If you also sell through your own website, at craft fairs, or on a platform that does not qualify as a marketplace facilitator, those direct sales still count toward your own nexus and require your own permit.
Multi-State Sellers and the Streamlined System
Remote sellers who need to collect tax in several states can register through the Streamlined Sales Tax Registration System instead of applying to each state separately. North Dakota is a member of the Streamlined Sales Tax Governing Board, and registering through that system satisfies the state’s permit requirement.2North Dakota Office of State Tax Commissioner. Sales and Use Tax Registration under the agreement does not by itself create nexus for other North Dakota taxes or fees.3North Dakota Legislative Branch. North Dakota Century Code 57-39.2 – Sales Tax – Section 57-39.2-14
What to Gather Before You Apply
The application asks for standard business identifiers. Have the following ready:
- Your Federal Employer Identification Number, or Social Security Number if you are a sole proprietor without an EIN
- The legal name and physical address of each business location in North Dakota
- Your North Dakota Secretary of State ID number, if you are a corporation, LLC, or partnership registered with that office
- The date you began or will begin making taxable sales in the state
- Names and contact information for the principal officers, partners, or members
State law also dictates who has to sign the application. A sole proprietor signs personally. A partnership or LLC needs a partner or member. A corporation needs an executive officer, and if anyone other than an officer signs, written proof of authorization must go with the application.3North Dakota Legislative Branch.

How to Apply Through ND TAP
Applications go through ND TAP, the North Dakota Taxpayer Access Point.5Office of State Tax Commissioner. ND TAP Information There is no fee to register, and you should submit at least 30 days before your first sale to give the tax commissioner time to process.2North Dakota Office of State Tax Commissioner. Sales and Use Tax
The application asks for your business name, the location of each place of business, and any other information the tax commissioner requires. Once the office confirms you are a legitimate retailer, you receive a permit for each business location.3North Dakota Legislative Branch. North Dakota Century Code 57-39.2 – Sales Tax – Section 57-39.2-14 Each permit is tied to a specific person and a specific address, and you must display it prominently where it was issued.
Permits are not transferable. If you sell your business or buy an existing one, the new owner has to apply for a new permit rather than take over the seller’s.2North Dakota Office of State Tax Commissioner. Sales and Use Tax
Local Taxes and Multi-City Sellers
Registration is a single process even if you sell across the state. More than 150 North Dakota cities impose their own local sales taxes on top of the 5% state rate, with local rates ranging from 0.5% to 3%.6North Dakota Office of State Tax Commissioner. Local Taxes by Location Guideline The Office of State Tax Commissioner administers those local taxes for the cities and counties, so no separate municipal registration is needed. Your state permit and state return handle local tax as well.2North Dakota Office of State Tax Commissioner. Sales and Use Tax
What Happens After You Register
Once your permit is issued, the tax commissioner assigns a filing frequency based on your expected sales volume. Quarterly filing is the default, with returns due on the last day of the month after each quarter. Businesses with $333,000 or more in taxable sales in the preceding calendar year file monthly.7North Dakota Legislative Branch. North Dakota Century Code 57-39.2 – Sales Tax – Section 57-39.2-12 Semi-annual and annual filing schedules are available for lower-volume sellers.8North Dakota Office of State Tax Commissioner. Sales and Use Tax Deadlines
All returns go through ND TAP, and a return is required for every period even if you had zero taxable sales. When a due date lands on a weekend or holiday, the deadline shifts to the next business day.
If You Should Have Been Registered Already
Businesses that discover they crossed the threshold or established physical presence in the past without registering can use North Dakota’s Voluntary Disclosure Program to come into compliance with reduced consequences.9North Dakota Office of State Tax Commissioner. Voluntary Disclosure Program Guideline Eligibility requires two things: you have not filed a return or made payments for the relevant tax in North Dakota, and you have not already been contacted by the Office of State Tax Commissioner or the Multistate Tax Commission about your filing status. You have to come forward before the state finds you.
The main benefit is a limited look-back period, generally three years, instead of assessment for every year you should have collected. The state may also waive penalties, though you still owe the tax and interest. If you actually collected tax from customers but never remitted it, full payment of the collected amounts is required, though penalties may still be waived.
Timing matters once the process begins. After you receive a Voluntary Disclosure Agreement, you have 60 days to sign and return it and another 30 days to submit the required returns, registration, and schedules. Missing either window voids the agreement, and the state can void it retroactively if it later finds misrepresentations.
