If a vendor doesn’t file a return, the Department of Revenue will issue a written notice requiring the return to be filed by the end of the month following the notice. If the vendor still doesn’t comply, the Department will create a return based on the best available information.

The resulting tax is treated as a deficiency and may incur penalties and interest. However, if the vendor submits the return within 30 days of receiving the notice, the Department may charge a $10 penalty.

Can I amend a Wyoming sales tax return?

Yes. You can file an amended form to correct any mistakes or omissions on your previous filed return.
