Unemployment tax

Register with the Wyoming Department of Workforce Services online to obtain a UI Account Number and tax rate. The tax rate generally ranges from 1.28%–4.16% for new employers. You should receive this info in 3 months after registering online.

If your company does not reside in Wyoming, you will need to complete both the online Joint Business Registration as well as an Out-of-State Questionnaire. The agency will not begin processing your registration until both the online registration and the Questionnaire have been received. The Questionnaire can be sent via email to DWS-UI-OSQ@wyo.gov or FAX to (307) 235-3278. 

Also, if your business is a 501(c)(3), you will need to provide a copy of your 501(c)(3) letter from the IRS. 

If you have any questions about the process you should call the agency at (307) 235-3217. 

Workers' Compensation

You can register with the Wyoming Department of Workforce Services for your Worker’s Compensation (WC) Employer Number using the same registration form that was used to obtain your UI Account Number. You should receive your Workers' Compensation Employer Number in 4-8 weeks after registering online.
