If you're registered for Wyoming sales tax, you must file returns and pay any tax due according to the filing frequency assigned by the Wyoming Department of Revenue. This guide focuses on the filing and payment process most relevant to remote sellers and out-of-state businesses using Wyoming Revenue Online. Note that Wyoming's due date is the last day of the month following the reporting period, which is later than the 20th deadline used by most other states.

How to prepare your Wyoming sales tax return
Before working on your sales tax return, collect all sales information for the tax period.
Sales transactions
You need to know your total gross sales to Wyoming buyers and your taxable sales. Wyoming generally taxes digital goods and SaaS, so those sales should be included in your taxable sales figures.
Key reporting figures
In addition to your gross Wyoming sales, filing a return requires:
- Total sales and income
- Taxable sales (Wyoming uses destination-based sourcing, so you charge the combined rate for the buyer's county)
- Non-taxable sales and exemptions
- Deductions and adjustments
- Total sales tax collected from customers during the filing period
How to complete and file a Wyoming sales tax return
Wyoming sales tax returns are filed electronically through Wyoming Revenue Online and must be reported in US dollars.
Step-by-step: file a Wyoming sales tax return
1. Collect all necessary information
Gather your sales records for the tax period. Wyoming uses destination-based sourcing, meaning the tax rate is determined by the buyer's county. The state rate is 4%, with county rates adding 1% to 2% on top of that.
2. Log in and file online
- Log in to Wyoming Revenue Online.
- Navigate to your Sales Tax account.
- Select the filing period you want to file.
- Enter your gross sales, taxable sales, exemptions, and total tax collected.
- Review and submit your return.
3. Receive confirmation
After submitting, you will receive a confirmation number. Save this as your record of filing.
How to pay sales tax in Wyoming
Wyoming requires businesses to file and pay electronically through Wyoming Revenue Online. You can pay directly within the portal after filing your return. Payment options typically include electronic bank transfers and other methods accepted through the portal.
What happens after filing and paying Wyoming sales tax
After filing and paying, keep a copy of your return and payment confirmation for your records.
- Save your filing confirmation and payment receipt
- Keep records supporting the reported amounts
- Continue filing according to your assigned frequency, remembering Wyoming's last-day-of-month due date

Late filing penalties and interest
If you miss a Wyoming sales tax filing deadline, file as soon as possible. Failure to file returns and remit collected tax on time results in penalties and interest charges that increase the longer you wait.
