Wyoming EIN Number: How to Get One (2026)

What is a Wyoming EIN number?

A Wyoming EIN number is the 9-digit federal tax ID the IRS assigns to a business registered in Wyoming. It is issued on Form SS-4, which carries 18 numbered fields. The IRS fee is $0 through every method.

The number prints in a 2-digit and 7-digit format, split by a hyphen. It belongs to the entity for the life of that entity. It never renews and never expires, which puts the cost in year 2 at $0 and the cost of every year after that at $0.

A Wyoming business uses the EIN to open a US bank account, to onboard with Stripe or PayPal, to file federal returns, and to hire. Wyoming itself asks for the EIN when a business registers for a sales and use tax license. The state does not issue the number and does not charge for it.

Word definitions for CP-575, ITIN, responsible party, and disregarded entity sit in the ein terms glossary.

Is a Wyoming EIN number different from another state’s EIN?

No. An EIN is federal. The same 9 digits, the same 18-field Form SS-4, and the same $0 fee apply in all 50 states. No state issues EINs, and no digit in the number marks it as Wyoming.

The IRS ended geographic EIN prefixes in 2001. Before that year the first 2 digits pointed to the service campus that issued the number. Since then the prefix points to the issuing system, so a Wyoming LLC and a Delaware corporation formed on the same day draw from the same pool.

What Wyoming controls is everything around the number: the entity that holds it, the fee to create that entity, the annual report, and the state tax account. Those 4 things change from state to state. The 9 digits do not.

How do you get a Wyoming EIN number?

Register the entity with the Wyoming Secretary of State for $100, wait for approval, then file Form SS-4 with the IRS. Applicants with an SSN file at irs.gov in 15 minutes. Applicants without one file by fax.

1. Appoint a Wyoming registered agent. Wyoming requires a registered agent with a physical street address inside the state. A P.O. box fails.
2. File Articles of Organization with the Wyoming Secretary of State ($100). Wyoming charges $100 to form an LLC and $100 to incorporate. Keep the filed copy: it holds your line 1 name and your line 11 date.
3. Wait for the Wyoming approval before you touch Form SS-4. The IRS issues EINs to entities that legally exist. An SS-4 filed before Wyoming approval gets rejected by mail.
4. Complete all 18 fields of Form SS-4. Line 1 copies the Wyoming name character for character. Line 6 takes the Wyoming county. Line 7b takes an SSN, an ITIN, or the word Foreign.
5. File it: irs.gov in 15 minutes, or fax. An SSN or ITIN on line 7b opens the online tool. Foreign on line 7b sends the form to 855-641-6935, or 855-215-1627 from outside the US.

Wyo. Stat. 17-29-108 requires the LLC name to end in one of 9 accepted forms: Limited Liability Company, Limited Company, Limited Liability Co., Ltd. Liability Company, Ltd. Liability Co., L.L.C., LLC, L.C., or LC. Whichever one the Articles of Organization carry is the one that goes on line 1 of Form SS-4. LLC and L.L.C. read as 2 different entities to the IRS.

The full field-by-field rule set lives on the Form SS-4 checklist, and the LLC-specific route lives on the EIN for an LLC page.

When in the Wyoming formation process do you apply for the EIN?

After the Wyoming Secretary of State approves the Articles of Organization, never before. Line 1 needs the approved name and line 11 needs the approval date. An SS-4 filed early gets rejected by mail.

This is the one sequencing mistake that costs Wyoming founders the most time. The IRS reports a rejected fax filing by mail, not by email, so a form sent 3 days early can burn weeks before the founder learns anything went wrong. Nothing in the process recovers those weeks.

Steps 1 to 3 are Wyoming. Steps 4 to 6 are federal and identical in all 50 states. Step 7 is Wyoming again, and most non-resident Wyoming LLCs skip it entirely.

Does a Wyoming EIN replace a Wyoming state tax registration?

No. The EIN is the federal number. A Wyoming sales and use tax license is separate and costs $60. Wyoming levies 0% personal income tax and 0% corporate income tax, so no state income account exists.

Wyoming is unusual here. In a state with a corporate income tax, a new entity opens a state income tax account soon after formation. Wyoming has no such account to open. The state raises revenue from sales and use tax instead: a 4% state rate published by the Wyoming Department of Revenue, plus county options capped at 2% more by the same department, so 4% + 2% sets the combined ceiling at 6%.

That leaves 2 clean triggers for a Wyoming state registration. Selling taxable goods or services with nexus in Wyoming triggers the $60 sales and use tax license. Paying wages triggers an unemployment insurance account with the Wyoming Department of Workforce Services. A Wyoming LLC that sells software to customers in Germany triggers neither.

How does a Wyoming LLC get an EIN number?

A Wyoming LLC gets an EIN by filing Form SS-4 after the state approves its Articles of Organization. Line 8a is Yes, line 8b takes the member count, and line 8c is Yes for a Wyoming LLC.

Line 8b decides federal tax treatment for the life of the entity. 1 member defaults to a disregarded entity. 2 or more members default to a partnership. The number on that line is the member count on the day of filing, not a plan for next year.

Line 8c asks whether the LLC was organized in the United States. A Wyoming LLC answers Yes, and it answers Yes even when every member lives outside the United States. Wyoming organized it, so the entity is domestic. The members’ residence changes federal reporting, not that answer.

What changes for a foreign owner forming in Wyoming?

Line 7b takes the word Foreign, lines 4a and 4b take a non-US mailing address, and the entity files Form 5472 every year. The IRS penalty for a missing Form 5472 is $25,000.

A single-member Wyoming LLC owned by a non-resident is a disregarded entity that still files. It files a pro forma Form 1120 with Form 5472 attached, once a year, reporting transactions between the LLC and its foreign owner. The EIN is the account number those filings post to, which is why the EIN comes before the first bank transfer, not after it.

Wyoming’s 0% income tax has no effect on that duty. State tax and federal reporting are 2 separate systems, and only 1 of them turned off.

Two address rules cause confusion. The registered agent’s Wyoming street address satisfies a Wyoming statute; it is not automatically the mailing address on line 4a. The IRS accepts a foreign mailing address on lines 4a and 4b, with the province, the postal code, and the country. Lines 5a and 5b stay blank when there is no separate US street address, and no P.O. box is accepted on line 5a.

Country-by-country detail for founders who own a Wyoming LLC from abroad sits on the ein by country page.

How do you get a Wyoming EIN number without an SSN?

Enter the word Foreign on line 7b of Form SS-4, then fax the form to the IRS. The IRS issues EINs to responsible parties holding no SSN and no ITIN. No passport and no identity document is required.

Line 7a still takes a person. A parent company, a Wyoming registered agent, or an accountant on line 7a triggers rejection. The IRS accepts exactly 1 responsible party per application, and that party has to be the individual who controls the entity and its funds.

How long does a Wyoming EIN number take?

An application filed at irs.gov with an SSN issues the EIN in 15 minutes. A faxed Form SS-4 takes days to weeks. Mail takes 4 weeks. einnumber.co files by fax within 5 business days, or within 24 hours.

Source: IRS Form SS-4 instructions, verified July 2026. Business days are Monday to Friday, excluding US federal holidays.

The IRS publishes the online assistant hours: Monday to Friday, 7 a.m. to 10 p.m. Eastern. The IRS also publishes the timeout, so the session ends after 15 minutes of inactivity and restarts from the first screen. The tool validates the responsible party against SSN and ITIN records, which stops applicants who hold neither at that screen, wherever the entity is formed.

The einnumber.co clock starts the moment your Wyoming details are complete. Standard files by fax within 5 business days and lands 12–14 business days total. Fast files within 24 hours with the IRS call included and lands under a week. Your confirmation email prints the filing date, and missing the filing window makes the filing free.

Full timing detail by method is on the how long does an EIN take page.

What does Wyoming charge every year after the EIN arrives?

Wyoming charges an annual report license tax of $60, or $0.0002 per dollar of assets located in Wyoming, whichever is greater. It falls due on the first day of the anniversary month of formation. The EIN costs $0 that year.

The formula is what separates Wyoming from states that bill a flat fee. Multiply the assets located in Wyoming by 0.0002, then compare that figure to $60 and pay the larger one. An entity holding assets outside Wyoming pays the $60 minimum.

Two rules attach to the date. The report is due on the first day of the anniversary month, so an LLC approved on 14 March owes it every 1 March after that. An entity left delinquent for 60 days is administratively dissolved by the Wyoming Secretary of State.

Administrative dissolution does not cancel the EIN. The IRS never reissues or deletes an EIN once it has been assigned. The number stays attached to that entity name permanently, and the IRS closes the business account on written request instead. That is 1 more reason line 1 has to be right the first time.

How much does a Wyoming EIN number cost?

A Wyoming EIN costs $0. The IRS charges nothing for Form SS-4 and nothing for the EIN, through every method. It costs $0 in year 2 and every year after, because an EIN never renews.

Competitor prices verified July 2026. Northwest reflects the no-SSN rate.

Read this before paying anyone, including us. Holding an SSN means the IRS issues your Wyoming EIN at irs.gov in 15 minutes for $0. The $67 exists for the applicants the online tool blocks: a paper form, a fax line with no tracking number and no status page, and 18 fields that have to be right the first time. $97 moves that filing to 24 hours and adds the IRS call.

Set beside the Wyoming state fees, the picture is simple. The state charges $100 to create the entity and a $60 minimum every year. The IRS charges $0 for the number, forever. The full breakdown sits on the how much does an EIN cost page, or get started with your EIN now.
