Wyoming rules in plain English

In Wyoming you need a sales tax license. The Wyoming Department of Revenue's Excise Tax Division issues it. You apply online through the Wyoming Internet Filing System (WYIFS) in two steps. First you open a WYIFS account, and once it is approved you apply for the license there. The Division says the whole process usually takes about two weeks. Paper applications are still accepted but take longer. The license costs $60, a one-time fee for new vendors. There is no renewal, but the license can be forfeited if you stop filing returns, and reinstating it costs another $60. Sellers outside Wyoming need a license once their sales into the state pass $100,000 in the current or previous calendar year. Since July 1, 2024, the number of transactions no longer counts. The state rate is 4%, and counties add local taxes. Tax is based on where the customer takes possession. The Division assigns monthly, quarterly or annual filing based on how much tax you collect. Returns are due the last day of the month after the period. The mistake to avoid: letting returns lapse. Missed returns can lead to forfeiture of the license and penalties.
