How to Get a Tax ID Number in North Dakota for a New Business

To get the appropriate tax ID number for a new North Dakota business, first determine whether you need a federal EIN, a North Dakota Sales Tax Permit, a state withholding account, or a combination of these registrations. North Dakota does not use one universal tax ID registration for every new business. The accounts you need depend primarily on whether the business will make taxable sales, hire employees, or conduct activities that trigger another tax or regulatory obligation.

Keep business formation and tax registration separate in your planning. If your business must be registered with the North Dakota Secretary of State, that registration is started through the FirstStop Portal after you choose a business structure, business name, and, when required, a registered agent. Completing a formation filing does not by itself answer which federal or state tax accounts the business needs.

Which tax ID does your North Dakota business need?

Start with the activities the business will perform rather than searching for a single “North Dakota tax ID.” Different business activities lead to different registrations.

A business selling products or services subject to North Dakota sales tax must apply for a North Dakota Sales Tax Permit. For more detail on that registration, see North Dakota State Sales Tax Number Identification Registration. Businesses buying items for resale may also want to review how to get a resale certificate in North Dakota, because a resale document and a sales-tax account serve different compliance purposes.

If the business plans to have employees, it must obtain an EIN if it does not already have one and apply for a North Dakota withholding account. State withholding applies when employees perform services in North Dakota or when the business is based in North Dakota.

Prepare the business information before applying

Using consistent information across formation and tax applications helps prevent avoidable mismatches. Assemble a working record containing the legal business name, any DBA or trade name, business structure, principal address, mailing address, responsible party details, expected business activities, and information about planned employees and taxable sales.

The legal name deserves particular attention. Use the name associated with the entity rather than casually substituting a storefront name, website name, or DBA. If an address, ownership detail, or business name is still unsettled, resolve it before submitting applications whenever practical. This reduces the chance that different registrations will describe the same business differently.

Also decide which registration must come first. A business that must complete a North Dakota Secretary of State registration should choose its structure, name, and registered agent, when one is required, before beginning that filing through the FirstStop Portal. A business planning to hire should identify its EIN and withholding needs. A seller should classify its products and services carefully enough to determine whether a Sales Tax Permit is required.

Licensing is a separate part of startup compliance. Tax registration does not necessarily address occupational, professional, local, or activity-based approvals. Use the Business License Requirements in North Dakota: Starter Checklist to organize that review without treating a license as a substitute for a tax account.

A practical registration sequence

1. Define the business structure and legal identity. Decide how the business will be organized and establish the exact name and address that will appear on its records.
2. Complete applicable business registration. North Dakota Secretary of State business registrations are started through the FirstStop Portal after the applicant chooses a structure, name, and, when required, a registered agent.
3. Determine whether the business needs an EIN. If applying, verify the responsible party information and check that another request has not already been submitted. The IRS limits issuance to one EIN per responsible party per day, regardless of whether the request is made online, by telephone, fax, or mail.
4. Evaluate sales-tax activity. If the company will sell products or services subject to North Dakota sales tax, apply for a North Dakota Sales Tax Permit. The overview of North Dakota State Sales Tax can help place this account in the broader sales-tax process.
5. Evaluate employment activity. A business planning to have employees must obtain an EIN if it does not already have one and apply for a North Dakota withholding account. Consider both where services will be performed and where the business is based.
6. Set up account management after approval. North Dakota Taxpayer Access Point, or ND TAP, is the Office of State Tax Commissioner’s online system for managing tax accounts, returns, and payments. To establish access, a user must first apply for and receive an approved Sales and Use or Withholding Tax Account.
7. Preserve the resulting records. Keep notices, identification numbers, account details, and copies of submitted information with the business’s permanent records. Share sensitive identifiers only with people who need them for legitimate business administration.

Do not treat ND TAP account access as the initial application for every type of state account. For the applicable Sales and Use or Withholding Tax Account, approval comes before the user establishes ND TAP access.

Common problems that delay a clean setup

Applying for a generic “state tax ID”

This wording can hide the actual decision. A seller may need a Sales Tax Permit, while an employer may need a withholding account. Some businesses may need both, and another business may need neither based solely on sales and employment. Name the account according to the activity it covers.

Confusing formation, licensing, and tax registration

These are related startup tasks, but they are not interchangeable. Organizing an entity does not automatically establish every tax account, and obtaining a tax number does not resolve every license question. Track each category separately so one completed filing does not create a false sense that all compliance work is finished.

Submitting duplicate EIN requests

Before making another EIN request, confirm whether a partner, owner, organizer, or service provider has already submitted one. The one-EIN-per-responsible-party-per-day limit applies across all application methods, not only to online requests. Coordinate responsibility for the filing and retain the resulting documentation.

Trying to enter ND TAP before account approval

ND TAP manages eligible state tax accounts after the relevant setup stage. A user seeking access must first apply for and receive an approved Sales and Use or Withholding Tax Account. Keep the approval information available when moving to account-access setup.

Overlooking changes in planned activity

A business model can develop between initial planning and opening. Recheck the registration decision if the company adds employees, begins making taxable sales, changes what it sells, opens another location, or enters a regulated line of business. The correct result should reflect actual operations rather than an outdated startup outline.

Final decision checklist

• Have you selected the business structure and exact legal name?
• If Secretary of State registration applies, have you identified the registered agent when one is required and started the filing through the FirstStop Portal?
• Have you determined whether the business needs an EIN and verified that no one else is submitting a duplicate request?
• Will the business sell products or services subject to North Dakota sales tax?
• Will employees perform services in North Dakota, or is the employing business based in North Dakota?
• Have you applied separately for each applicable state account instead of looking for one universal North Dakota tax ID?
• Have you waited for approval of the applicable Sales and Use or Withholding Tax Account before trying to establish ND TAP access?
• Have you reviewed licenses and regulated activities separately from tax registration?
• Are the legal name, address, responsible party details, and business activity descriptions consistent across filings?
• Have you saved the approval notices and account information in a secure business record?

The central task is to match registrations to operations. Establish the business identity, identify the federal and state accounts associated with planned sales and employment, complete each applicable registration, and preserve the resulting account information for ongoing administration.
