An EIN is the federal tax-identification number the IRS assigns to a business or other entity. The number itself is free directly from the IRS. Form the Wyoming LLC first, then apply through the IRS route that matches where the business is principally located and whether the responsible party has an SSN or ITIN.

What an EIN Is & Who Needs One
An Employer Identification Number (EIN) is a nine-digit federal tax ID the IRS issues to your business. It identifies your LLC on tax filings the way a Social Security number identifies a person. For a Wyoming LLC, you'll use it to open a business bank account, hire employees, and file taxes.
- Multi-member LLCs must have one — it's required for partnership tax filing.
- Any LLC with employees must have one — it's needed for payroll taxes.
- Single-member LLCs with no employees can technically use the owner's SSN, but an EIN is strongly recommended — banks require it and it keeps your SSN private (a nice fit with Wyoming's privacy focus).
Never pay for an EINThe EIN itself is 100% free directly from the IRS. Sites that charge $50–$300 for "EIN filing" are just filling out a free form for you. Apply yourself at IRS.gov, or let your formation service include it.
EIN Application Method Finder
The right application route depends on where the business's principal place of business is located and whether the responsible party has an SSN or ITIN. Use the finder below as a practical guide.
The route depends on where the business is principally located and the responsible party's taxpayer ID.
Who Is the Responsible Party?
The IRS requires the EIN application to identify the responsible party—generally the person who ultimately owns or controls the entity or exercises effective control over it and its assets. For most privately owned LLCs, that means a real individual rather than a formation-company nominee.
- Use the actual responsible party: nominees are not authorized to apply as the responsible party.
- Online application: the responsible party needs an SSN or ITIN and the principal place of business must be in the U.S. or a U.S. territory.
- Daily limit: the IRS limits applications to one EIN per responsible party per day.
How to Apply, Step by Step
- Wait until your LLC is approved. Apply only after the Secretary of State has accepted your Articles, so your details match.
- Online (with SSN/ITIN): use the IRS EIN Assistant, Monday–Friday, and you'll get your number instantly at the end.
- By fax/mail (Form SS-4): complete Form SS-4 and submit it — about 4 business days by fax, 4 weeks by mail.
- Save the confirmation letter (CP 575). Your bank will ask for it — keep a copy with your records.

After the EIN: Prepare for Business Banking
An EIN is commonly part of an LLC's banking setup, but each financial institution decides what documents it requires. Before applying, keep your formation document, EIN confirmation and signed operating agreement available.
Bank requirements varyDo not assume an EIN alone guarantees account approval. Banks may request formation documents, ownership/control information, identification, an operating agreement, business address information or other compliance documents. Compare business banking options →
