Steps to filing sales tax in Wyoming
Filing your sales tax returns in Wyoming is straightforward. As long as you understand what’s taxable and keep diligent records, you can handle this essential requirement for retailers and service providers.
Step 1: Create an online account
The first step is to create an online account with the Wyoming Department of Revenue's Tax and Revenue Center. This is mandatory for modern electronic filing. Visit the direct sign-up link and check the box to agree to the terms and conditions.

Select "No" when asked if you need to convert an existing account.

Then enter all required personal and business information to complete your registration. This includes:
- Name
- Contact details
- Social Security Number
- Federal EIN (if applicable)
- Business classification
- Sales tax license number

Make sure everything matches the details on your sales tax permit. It can take up to 72 hours to receive your account PIN by email after signing up. This allows you to access the system.
Step 2: Login and access sales tax forms
Once your account is active, visit the Wyoming Department of Revenue website and click “Sign In” to log into your account. Enter your new credentials when prompted.

Navigate to the sales tax section.

Here you will find your sales tax license number, registered business name, account balance, and links to file returns. You can also submit license applications if you need to register a new establishment.
Step 3: Enter tax details
Now it’s time to work on your actual sales tax returns. In your account, access and open the forms for your reporting period. You'll need to file monthly, quarterly, or annually based on your business activities.

The sales tax return form has four sections:
- Page 1) Overview of gross sales and allowed exemptions
- Page 2) Calculation of purchases subject to use tax
- Page 3) Local tax jurisdiction breakouts
- Page 4) Summary totals and amount due
Note: These pages are subject to change when their systems upgrade.
Enter gross sales and deductions first. Allowable exemptions include merchandise purchased for resale, ingredient costs at restaurants, and sales shipped out of state. The cost of goods sold cannot be deducted though.
Next, determine any use tax owed on out-of-state purchases, which offsets uncollected sales tax. Complete local tax sections if operating in multiple cities/counties. Finally, summarize totals and calculate administrative fees based on filing frequency.
Step 4: Submit payment
Double-check your sales tax form to verify all entries appear correct. Misreporting amounts or tax due dates can lead to penalties and interest charges. After reviewing, proceed to online payment.

Choose your preferred payment method–electronic bank check or credit/debit card.

Enter details and submit payment to finalize your return for the period. Make sure to avoid rejected payments by updating any expired cards or low account balances.
Step 5: Finalize and keep records
Print or download a copy of your completed sales tax return and payment confirmation for your records right away. Retain returns, receipts, and all supporting tax documents for a minimum of 3 years.
Congratulations - you successfully filed and paid sales tax in Wyoming for the period! Repeat these steps regularly per your assigned filing frequency to avoid disruptions.

FAQs
When is my sales tax return due in Wyoming?
The due date for filing your Wyoming sales tax return is the last calendar day of the month following the end of the reporting period. For example, if your reporting period ends on January 31, your sales tax return must be filed by February 28. It is crucial to file by the due date to avoid any late fees or penalties.
How often do I need to file sales tax returns?
The sales tax return filing frequency in Wyoming is monthly for most general retail businesses. Some exceptions are made for seasonal retailers and smaller operations, which may qualify to file returns quarterly instead of monthly. To confirm your required filing frequency, check in with the Wyoming Department of Revenue or review the notice you received when registering for your sales tax license.
What if I accidentally collect excess sales tax from my customers?
If you inadvertently collect too much sales tax from customers, you still need to remit the full tax amount to the state of Wyoming as per the law. Later, you can file an amended return or claim a credit on your next return to reconcile the over-collection. It is not legal to keep any excess sales tax collected.
What sales tax records do I need to retain? For how long?
You must keep detailed records, such as sales invoices, receipts, purchase logs, and tax collection logs for a minimum of three years. These records must be provided if you receive an audit request from the Wyoming Department of Revenue. Proper documentation is crucial for supporting all taxes collected and remitted.
Which Wyoming businesses must collect sales tax?
If you are launching a new startup or small business in Wyoming, mandatory sales tax registration hinges primarily on your expected gross revenue. The Department of Revenue guidelines say that "engaging in business" means:
- Having $100,000+ in gross sales OR
- Conducting 200+ separate transactions
You need to obtain a seller's permit once exceeding either threshold based on the prior year's revenue. Unfortunately "hobby" businesses or mini side gigs no longer avoid requirements once hitting these realistic volume markers.
Note that SaaS products are not taxable in Wyoming.
