Guides a business through determining nexus, registering with the North Dakota Office of State Tax Commissioner, and preparing and filing the North Dakota Sales and Use Tax Return (Form ST) covering state (5%) and applicable local rates, including SST sourcing rules for remote sellers.
Determine whether the business has physical or economic nexus in North Dakota. Economic nexus is triggered at $100,000 in gross sales into the state in the current or prior calendar year. North Dakota is a full SST (Streamlined Sales Tax) member, so multistate sellers using a Certified Service Provider (CSP) may register via the SST central portal instead of directly with the state.
Classify each product or service line against North Dakota's taxability rules. Key distinctions: SaaS and specified digital products are taxable at the full state rate; grocery food is exempt while prepared food is taxable; professional services are not taxable; manufacturing equipment and prescription drugs are exempt. Collect valid exemption certificates (ND Form E-595 or SST Exemption Certificate) from any exempt customers.
Apply destination-based sourcing rules to each North Dakota sale. The state rate is 5.00%; add the applicable local city or county rate (up to 3.50%, combined max ~8.50%) based on the ship-to address. Identify any untaxed purchases on which use tax is owed by the business itself (out-of-state purchases consumed in ND where the vendor did not collect ND tax).
Complete and file the North Dakota Sales and Use Tax Return (Form ST) through the Taxpayer Access Point at tax.nd.gov. Report gross sales, allowable deductions (exempt sales, out-of-state sales, etc.), taxable sales, state tax due at 5%, and local tax due by jurisdiction. Returns and payment are due by the 25th of the month following the close of the filing period.
