How to File Sales Tax in Wyoming


How to Register: You may apply online or by downloading and mailing in the appropriate form.

Registration Cost: One-time fee of $60.

Filing Requirements: Sales taxes are reported on Forms 41-1 or 42-1. These forms are pre-printed with the vendors “Doing Business As” (d/b/a) name, address, license number, filing period, and due date. A barcode on the form identifies the particular filing period as well as other identifying information of the vendor. The returns are mailed or posted on the online 30 days prior to the due date of the return. If you are going to file via paper, these pre-printed forms must be used.

If you would like to use the online system, once you are registered user, (completing your user name and password and receiving a PIN number from the Department) you may apply online and complete your returns online.


Due Date: Returns are due on or before the last day of the month following the last month in the reporting period in which the sale occurred.

Where to File: Wyoming Internet Filing System for Business

What Will You Need: Submitting a return is a multipage process. Page 1 will reconfirm your business information and allows for a bypass if the business had no sales for the period.

There will be jurisdiction(s) listed that the system expects you to be reporting in based on your last return. If you need to file taxes in a jurisdiction not already listed in the Table, select the jurisdiction from the drop down list and “Add”. If you do not know the county, you can search by Zip Code.

Once you have submitted your return, you will be directed to a CONFIRMATION Screen. Once here you will be prompted to (a) print a copy of the return for your records, (b) print a voucher to submit with a paper check, or (c) submit the payment electronically – either E-Check or Credit Card

Please note: You may choose to file electronically and still pay by check. Renewal:
