How to get an EIN in North Dakota comes down to one free federal step, as of 2026. The IRS issues the EIN at no cost through its online EIN Assistant, usually the same day, and a North Dakota LLC then opens any tax accounts it needs through ND TAP, with unemployment handled separately by Job Service North Dakota.
North Dakota EIN: The Short Version
A North Dakota EIN is a free federal tax ID issued by the IRS, not a state number, and most LLC owners receive it online the same day once the North Dakota Secretary of State approves the company; state tax accounts come afterward through ND TAP. Single-member and multi-member LLCs, plus any business that hires or sells taxable goods, will want one before banking or payroll.
- Cost: $0 directly from the IRS. Paid filing sites charge $150 to $300 for the same free service.
- How: Online EIN Assistant, same day, or Form SS-4 by fax, around 4 business days, or mail, roughly 4 weeks.
- Hours: Monday to Friday, 6:00 a.m. to 1:00 a.m. ET, with shorter weekend windows.
- State accounts: withholding and the Sales and Use Tax Permit through ND TAP; unemployment through Job Service North Dakota.
- Contacts: IRS Business and Specialty Tax Line, 800-829-4933; international applicants call 267-941-1099.
Does Your North Dakota LLC Need an EIN?
Not every North Dakota LLC is legally required to hold an EIN, but almost every one ends up needing it. A single-member LLC with no employees counts as a disregarded entity, so the IRS lets the owner file federal taxes under a Social Security number.
That logic breaks the moment the business hires, adds a second member, or wants a bank account, since banks won’t open one without the number. It helps to form the North Dakota LLC first, then read the table below against your own setup.
| Business type | EIN required? | Notes |
|---|---|---|
| Single-member LLC, no employees | Not federally required | Disregarded entity; still smart for banking and payroll readiness |
| Single-member LLC with employees | Yes | Needed for payroll and withholding |
| Multi-member LLC | Yes | Taxed as a partnership by default |
| LLC taxed as S-corp or C-corp | Yes | Required for the corporate election and payroll |
| Sole proprietor, no employees | Not required | Optional; avoids sharing an SSN |
| Partnership | Yes | Always required |
A multi-member LLC needs the number from day one because the IRS treats it as a partnership. If the members haven’t documented their ownership split, a clear North Dakota operating agreement belongs in place before payroll and tax filings start.
How to Apply for Your North Dakota EIN Online
The fastest route is the online application, and it works once the LLC is approved and the responsible party has an SSN or ITIN ready. The IRS issues the number on the spot when the application clears, so there’s no waiting on the mail.
- Confirm your LLC is approved: The EIN name has to match the Secretary of State record, so owners wait for FirstStop approval first. How long North Dakota LLC approval takes depends on the filing method.
- Open the IRS EIN Assistant: It runs Monday to Friday 6:00 a.m. to 1:00 a.m. ET, Saturday 6:00 a.m. to 9:00 p.m. ET, and Sunday 6:00 p.m. to midnight ET as of 2026.
- Choose the entity type: This is the screen that trips people up; an LLC selects “Limited Liability Company,” not “Corporation,” unless it has filed Form 8832 or Form 2553.
- Enter the legal and trade names: The legal name must match the Articles of Organization; any DBA goes in the trade-name field.
- Name the responsible party: A natural person with an SSN or ITIN, never a nominee or another company.
- Download the CP 575 right away: The IRS won’t resend this confirmation notice, so save the PDF and print a copy before closing the window.
North Dakota EIN Approval: Save Your CP 575 Before You Open ND TAP, UI EASY, or WSI
When the IRS approves your online EIN application, the confirmation letter is the CP 575. This is the document you save before closing the IRS screen, because it proves the federal EIN you will use for banking, payroll setup, ND TAP tax accounts, Job Service North Dakota unemployment, and WSI workers’ compensation.
The CP 575 should match your North Dakota LLC record.
Before you move on to state registrations, confirm that the legal name on the letter matches the LLC name approved by the North Dakota Secretary of State. Do not confuse this federal EIN letter with any state account number issued later.
- Use the EIN for your bank, W-9s, payroll setup, and state account registrations.
- Use ND TAP separately for withholding and Sales and Use Tax Permit accounts.
- Use UI EASY and WSI separately for unemployment and workers’ compensation steps.
Sample IRS CP 575 EIN confirmation letter for a North Dakota LLC.
Save it immediately: the IRS will not reissue the original CP 575 if you lose it. If you need proof later, an authorized person can request a 147C verification letter from the IRS, but that is not the same as downloading the original confirmation when it first appears.
Owners who can’t file online have other paths. Faxing Form SS-4 runs around 4 business days with a return fax number, mail takes roughly 4 weeks, and applicants whose principal business sits outside the U.S. can call 267-941-1099 on weekdays. Either way, the form and the IRS EIN application itself cost nothing.
That free part matters, because sites charging $150 to $300 for a “North Dakota EIN filing” are selling help with something the government does for free. Owners weighing setup help can see which North Dakota formation services earn their fee instead.
One rule catches repeat filers: the IRS issues only one EIN per responsible party per day, no matter whether the request comes online, by fax, by phone, or by mail.
Keep the North Dakota LLC and EIN records lined up before state accounts.
The EIN is free from the IRS, but the filing still needs to match your North Dakota Secretary of State record before you use it for banking, ND TAP, UI EASY, WSI, or payroll setup. Bizee can help with North Dakota LLC formation and optional EIN filing support, so the legal name, responsible party, and CP 575 record stay organized from the start.
What You Need Before You Apply for an EIN in North Dakota
A little prep keeps the session from expiring, since the online application can’t be saved and times out after 15 minutes of inactivity. Most owners who gather these details first finish in a single sitting.
- Approved LLC legal name: Exactly as it reads when you search the Secretary of State’s records, including the “LLC” ending.
- Formation details: The entity type and formation date from the Articles of Organization filed through FirstStop.
- Responsible party and TIN: A natural person’s SSN or ITIN.
- Reason for applying: Usually “started a new business” for a fresh LLC.
- Registered agent and address: North Dakota requires a North Dakota registered agent with a physical in-state address.
Order matters more than people expect. In Aaron Kra’s experience filing across 25-plus states, the name-mismatch refile is the most avoidable mistake of all, and it shows up whenever owners apply for the EIN before the state approves the LLC. Budget separately for what a North Dakota LLC costs to set up, since those state fees have nothing to do with the free federal number.
EIN vs North Dakota State Tax ID: ND TAP, UI EASY, and WSI
A federal EIN and a North Dakota state tax account aren’t the same thing, and mixing them up is the most common error in the state’s payroll setup. The EIN comes from the IRS; the state accounts come from three different North Dakota agencies, each with its own portal.
| Identifier | Issued by | Used for |
|---|---|---|
| Federal EIN | IRS | Banking, payroll setup, W-9s, 1099s, opening state accounts |
| Sales and Use Tax Permit | ND Office of State Tax Commissioner (ND TAP) | Collecting and remitting state and local sales/use tax |
| Income Tax Withholding account | ND Office of State Tax Commissioner (ND TAP) | Withholding state income tax, filing Form 306 |
| UI employer account | Job Service North Dakota (UI EASY) | Paying unemployment contributions and wage reports |
| WSI account | North Dakota Workforce Safety and Insurance | Workers’ compensation coverage before hiring |
One caution before anyone copies a number off a payroll blog: third-party pages publish conflicting North Dakota withholding and UI account formats. The agencies confirm the accounts and portals, so owners should pull their exact numbers from ND TAP and UI EASY directly.
The mix-up I see most isn’t even federal. Last year, a client in Fargo handed their payroll provider the Secretary of State entity number, swore it was the “state tax ID,” and ran two months of withholding under an account that didn’t exist.
We fixed it with one call to ND TAP and a corrected return, but it cost them a late filing. So I tell every hiring client the same thing: write down four numbers and label which agency owns each.
My rule: label the EIN, the ND TAP withholding ID, the Job Service UI account, and the WSI policy before payroll starts. It takes five minutes and saves a quarter of cleanup.
How to Register North Dakota Tax Accounts After Your EIN
The EIN unlocks the state layer, and North Dakota spreads it across more than one portal. Which accounts a business opens depend on whether it hires, sells taxable goods, or both, so there’s no single registration that covers everything.
ND TAP Income Tax Withholding Account
An employer paying wages for work done in North Dakota generally has to withhold state income tax and open a withholding account with the Office of State Tax Commissioner through ND TAP. Filing runs on Form 306, and the Form 307 reconciliation is satisfied by e-filing W-2s and qualifying 1099s.
North Dakota adds a payroll quirk that generic guides skip: wages paid to Minnesota and Montana residents working in the state are exempt from North Dakota withholding when the worker files Form NDW-R, under reciprocity agreements with both neighbors.
ND TAP Sales and Use Tax Permit
A business selling taxable goods, recreational admissions, or lodging needs a Sales and Use Tax Permit, also through ND TAP, and the state asks applicants to register about 30 days before opening. The base rate is 5%, with local city and county taxes on top in many areas, as North Dakota’s sales and use tax rules spell out.
A Bismarck storefront and an out-of-state web shop don’t register the same way. Remote sellers with no physical presence register only once taxable sales into North Dakota top $100,000 in the current or prior calendar year, while marketplaces like Etsy or Amazon collect the tax on sales made through them.
Job Service North Dakota Unemployment Insurance (UI EASY)
Hiring triggers a second agency entirely. Employers register for unemployment insurance with Job Service North Dakota through UI EASY within 20 days of first employing workers, and liability generally starts at $1,500 in wages in a calendar quarter, per Job Service North Dakota’s employer guide.
For 2026, the taxable wage base is $46,600, and the new-employer rate for most non-construction businesses is 1.00% on a positive account balance. Construction new employers pay a far steeper rate, so the industry code on the application isn’t a throwaway field.
WSI Workers’ Compensation
North Dakota runs workers’ compensation differently from almost every other state, and it’s the step that ambushes new employers.
Here’s the one that blindsides out-of-state founders every time. North Dakota is a monopolistic state, so there’s no private workers’ comp carrier to shop; coverage runs only through WSI, and it has to be active before the first employee clocks in, not the week after.
I watched a contractor try to start a three-person crew on a Monday with the WSI application still pending, and it was a flat stop, no work until coverage cleared.
My rule: set up WSI the week before you hire, not the morning of.
Local and Special Taxes
Beyond the core accounts, North Dakota layers on transaction-specific taxes that hit only certain businesses. These run from local lodging and restaurant taxes and motor vehicle rental tax to gross receipts rates such as 7% on alcohol and 3% on new farm machinery used in agriculture.
Every ND TAP account asks for the EIN during setup, which is exactly why the federal number comes first. Once those accounts are live, the LLC keeps up its other filings, including the North Dakota LLC annual report due each November 15.
North Dakota EIN Mistakes That Cost LLC Owners Time
A short list of errors shows up again and again on North Dakota applications. None is fatal when caught early, but each one can stall payroll or trigger a late filing.
- Choosing the wrong entity type on Form SS-4: Marking “Corporation” for a standard LLC creates a classification snarl that often forces a refile.
- Naming a nominee instead of a real person: The responsible party has to be a natural person with an SSN or ITIN.
- Assuming the EIN covers state obligations: It doesn’t; ND TAP, UI EASY, and WSI are all separate registrations.
- Treating ND TAP as the whole state: It handles tax accounts, but the unemployment account lives in UI EASY at Job Service North Dakota.
- In-state sellers waiting for the $100,000 mark: That threshold is for remote sellers; a business with physical presence registers when it starts selling taxable goods.
- Skipping WSI before the first hire: Coverage must be active before anyone starts work, with very limited exceptions.
How to Find a Lost EIN or Update Your North Dakota LLC
Losing an EIN happens, and it’s almost never a real problem. The original CP 575, a prior tax return, or the business bank account all carry the number, and an authorized person can request a 147C verification letter from the IRS by phone.
Anyone who needs to track down your federal tax ID can pull it from those records, then find the matching state accounts in ND TAP and the employer account in UI EASY.
A new EIN isn’t always required, though. Structural changes, like converting a sole proprietorship to an LLC or adding members to a single-member LLC, call for a fresh one, while a simple name or address change uses Form 8822-B, and a tax-classification change uses Form 8832.
Common North Dakota EIN Questions from LLC Owners
These are the questions North Dakota LLC owners ask most when setting up. Each answer reflects current IRS and North Dakota agency guidance as of 2026.
Is a North Dakota EIN the same as a federal EIN?
Yes, they’re identical. North Dakota doesn’t issue its own EIN; the “North Dakota EIN” people search for is simply the federal IRS number used by a business based in the state. Any separate North Dakota numbers are state tax accounts, not EINs.
What is ND TAP, and is it the same as my EIN?
No. ND TAP is the North Dakota Taxpayer Access Point, the online portal where the Office of State Tax Commissioner issues withholding and sales tax accounts. It sits entirely apart from the federal EIN, and a business uses the EIN to register inside ND TAP.
When does a North Dakota employer have to register with Job Service North Dakota?
Within 20 days of first employing workers. Unemployment liability generally kicks in once a business pays $1,500 or more in wages in a single calendar quarter, or employs at least one worker in 20 different weeks of the year, so most employers register right after their first hire.
Does North Dakota require WSI workers’ comp before the first employee starts?
Yes, and there’s no way around it. Coverage through Workforce Safety and Insurance must be active before any employee begins working, and WSI is the only provider in the state because North Dakota doesn’t allow private workers’ comp carriers.
Do Minnesota or Montana residents change North Dakota payroll withholding?
They can. North Dakota holds reciprocity agreements with both states, so wages paid to qualifying Minnesota and Montana residents working in North Dakota are exempt from state withholding once the worker hands the employer a completed Form NDW-R.
Can a non-US resident get an EIN for a North Dakota LLC without an SSN?
Yes. An applicant without an SSN or ITIN can’t use the online tool, but can still get an EIN by filing Form SS-4 by fax or mail. Owners whose principal business is outside the U.S. can also call the IRS international line at 267-941-1099 on weekdays.
