North Dakota Sales Tax Guide for Small Businesses and Online Sellers

North Dakota sales tax is simple at a glance, but the details matter. State rates, local taxes, remote seller rules, exemption certificates, and filing deadlines can all affect how much tax your business must collect and remit.

If you sell taxable goods, certain admissions, or lodging accommodations in North Dakota, you need a clear process for registration, collection, filing, and recordkeeping. This guide explains the main rules so you can stay compliant and avoid unnecessary penalties.

How North Dakota Sales Tax Works

North Dakota charges a 5% state sales tax on most retail sales. In addition to the state rate, cities and counties may impose local sales and use taxes. Some local jurisdictions also levy special taxes such as lodging taxes, lodging and restaurant taxes, and motor vehicle rental taxes.

In practice, that means the tax rate you collect can vary depending on where the sale is sourced or where the item is delivered. Using the state rate alone is not enough.

A few special rates also apply in limited situations:

• Alcohol at 7%
• New farm machinery used exclusively for agricultural production at 3%
• New mobile homes at 3%

What Is Taxable in North Dakota?

North Dakota sales tax generally applies to retail sales of tangible personal property. Some business categories also face tax on specific transactions, including admissions to recreational activities and lodging accommodations.

Common taxable examples include:

• Store inventory sold to customers
• Equipment and office supplies
• Many in-state retail transactions
• Lodging and certain admissions
• Taxable items sold through a marketplace platform

If you are unsure whether a product or service is taxable, it is better to verify before you start collecting. Incorrectly treating a taxable sale as exempt can create back taxes, interest, and penalties.

Who Must Collect Sales Tax?

You generally need a North Dakota sales tax permit if you:

• Have a physical presence in North Dakota and sell taxable goods or services
• Operate a retail business that sells taxable tangible personal property, lodging accommodations, or admissions to recreational activities
• Sell taxable items online into North Dakota and meet the remote seller threshold
• Operate as a marketplace facilitator that is responsible for collecting and remitting tax

Remote Sellers

North Dakota requires remote sellers with no physical presence in the state to collect state and local sales tax once taxable sales into North Dakota exceed $100,000 in a calendar year. Once that threshold is met, the seller must register and begin collecting according to the state’s rules.

Marketplace Facilitators

Marketplace facilitators can also be required to collect North Dakota tax. If a facilitator has physical nexus in the state, it must collect and remit tax. If it does not have physical nexus, it generally must collect once taxable sales delivered into North Dakota exceed $100,000 in the current or prior calendar year.

How to Register for a North Dakota Sales Tax Permit

North Dakota says sellers should apply for a sales and use tax permit about 30 days before opening for business. If you buy an existing business, you need to apply for your own permit because permits are not transferable.

The application is available through ND TAP, North Dakota’s online taxpayer portal.

Before you apply, gather:

• Your legal business name and address
• Federal Employer Identification Number
• Business ownership details
• Expected start date and sales activity
• Any supporting information needed for your business type

Once registered, keep your permit information in a secure place and use it whenever you file returns or request exemption certificates.

How to Calculate the Right Tax

To calculate North Dakota sales tax correctly, you need to know:

• Whether the transaction is taxable
• Which state rate applies
• Which local taxes apply
• Whether any special tax or exemption changes the total

For businesses that sell in multiple locations or ship to different destinations, a tax rate locator is essential. North Dakota’s local taxes are location-based, so the rate can change from one city or county to another.

Good recordkeeping helps here. Each transaction should show:

• Date of sale
• Item or service sold
• Tax collected
• Destination or delivery location
• Exemption certificate, if applicable

Filing and Paying Sales Tax

North Dakota sales and use tax returns can be filed through ND TAP. If you have a permit, you will be assigned a filing frequency, and you must file each period whether tax is due or not.

That point matters. A zero-tax period still needs a return.

When you file, you typically report:

• Gross sales
• Taxable sales
• Exempt sales
• Sales tax collected
• Use tax owed on taxable purchases where no tax was charged

If tax is due, pay it by the deadline assigned to your filing period. Late filing can trigger penalties, even when the amount due is small.

How Use Tax Works

Use tax is the companion to sales tax. If you buy taxable tangible personal property for storage, use, or consumption in North Dakota and the seller did not collect the correct sales tax, you may owe use tax instead.

This often comes up when businesses:

• Buy equipment from out-of-state vendors
• Order office supplies online
• Bring property into North Dakota for use in the state
• Purchase items in another state where the tax collected was lower than North Dakota’s applicable rate

For businesses, use tax is easy to miss because it often shows up after the purchase, not at checkout. Reviewing vendor invoices and purchase records regularly can prevent surprises.

Common Exemptions and Certificates

Not every sale is taxable. North Dakota law includes a number of exemptions, but exemption claims need documentation.

Common exempt categories include:

• Sales to government entities
• Certain sales to tribal governments or tribal members in qualifying situations
• Specific organizations and institutions that meet North Dakota’s exemption rules
• Purchases for resale
• Certain manufacturing, processing, agricultural, and contractor purchases when the correct certificate is used

Important: North Dakota does not provide a blanket exemption for all religious, charitable, or nonprofit organizations. Some purchases by churches are taxable, although certain printed religious materials may be exempt under state law.

For business purchases, the right certificate matters. Examples include:

• Certificate of Resale
• Certificate of Processing
• Contractor’s Certificate
• Streamlined Sales Tax Certificate of Exemption
• Multistate Tax Commission Uniform Sales and Use Tax Resale Certificate

If you accept an exemption certificate, keep it on file. In an audit, missing documentation can turn an otherwise exempt sale into a taxable one.

Local Taxes, Caps, and Refunds

Some North Dakota cities and counties impose local maximum taxes, sometimes called tax caps. If the tax charged on a transaction exceeds the local maximum, the purchaser may be able to request a refund from the state.

This is especially relevant for larger purchases where the local cap can limit the amount of tax due on a single invoice. Businesses that invoice customers should understand local caps before collecting tax on big-ticket items.

What Can Trigger an Audit?

North Dakota may review businesses that have:

• Missing or late returns
• Repeated payment problems
• Inconsistent sales figures
• Exemption certificates that are incomplete or misused
• Significant differences between reported sales and known business activity

The best defense is organized records. Keep copies of:

• Filed returns
• Proof of payment
• Exemption certificates
• Purchase invoices
• Sales reports from your point-of-sale or ecommerce platform

A clean paper trail reduces the time and cost of responding to questions later.
