After your EIN in Wyoming
| Account | Agency | Number you get | Register |
|---|---|---|---|
| State income tax withholding | None | Wyoming does not tax wages | Not needed |
| Unemployment insurance | Wyoming Department of Workforce Services | Account number issued at registration | WYUI |
| Sales tax | Wyoming Department of Revenue | Sales tax license | WYIFS |
Wyoming's Department of Workforce Services uses one joint business registration on WYUI to determine whether the business needs unemployment insurance and coverage under the state Workers' Compensation fund. Businesses based outside Wyoming also complete an out-of-state questionnaire.
Wyoming's Department of Workforce Services asks every new employer to complete its joint business registration, even a business that may be non-liable or optional under the state Workers' Compensation fund, because the registration is how DWS decides which coverage you need.
Getting a Wyoming sales tax license is a two-step process on the Department of Revenue's Wyoming Internet Filing System (WYIFS). You first apply for a WYIFS account, and once that is approved you use the same system to apply for the license and then manage the account.
Also on the Wyoming list
- File the annual report and pay the annual report license tax with the Secretary of State by the first day of the anniversary month each year; the tax is based on assets located in Wyoming.
- Register with the Wyoming Department of Revenue for a sales and use tax license if the LLC sells taxable goods or services, and with the Department of Workforce Services for unemployment insurance when it hires. Both ask for the EIN.

What is different about Wyoming
- Wyoming's articles of organization do not list the members or managers, so the public record shows only the company name, the registered agent, and the organizer. The annual report is where a manager or member signs, which is why Wyoming is chosen for privacy and why the annual report is the filing that matters.
- Wyoming has no state income tax and no general state business license, so for most LLCs the only recurring state filing is the Secretary of State annual report with its license tax, which is computed on assets located in Wyoming rather than on income. Above a certain tax amount the report must be filed on paper rather than online.
- The Wyoming Secretary of State assigns a filing ID at registration, and the online annual report wizard runs on it rather than on the company name. Owners who do not have the ID can look it up on the first page of the annual report screens by searching the LLC name.
Before you apply
The SS-4 must match the Wyoming Secretary of State, Business Division filing; its filing ID is a state index, not a tax ID.
Wyoming EIN questions
How do I get an EIN number in Wyoming?
File IRS Form SS-4 after the Wyoming Secretary of State, Business Division approves any formation filing; there is no Wyoming EIN application. Wyoming's Department of Workforce Services uses one joint business registration on WYUI to determine whether the business needs unemployment insurance and coverage under the state Workers' Compensation fund. Businesses based outside Wyoming also complete an out-of-state questionnaire.
Is there a Wyoming EIN or state tax ID number?
No; only the IRS issues EINs (also called the FEIN or federal tax ID). Wyoming's own numbers are the filing ID from the Wyoming Secretary of State, Business Division and the sales tax license from the Wyoming Department of Revenue.
Does Wyoming have state income tax withholding?
No. Wyoming does not tax wage income, so there is no state withholding account to open. The payroll registration Wyoming does have is unemployment insurance, with the Wyoming Department of Workforce Services through WYUI.
Where do I register for Wyoming unemployment insurance?
With the Wyoming Department of Workforce Services, online through WYUI. The account is separate from the federal EIN, which the registration asks for.
Do I need a Wyoming sales tax license?
Only if you sell what Wyoming taxes. The Wyoming Department of Revenue issues it through WYIFS, and your returns are filed under its number, not the EIN.
