Steps to register for sales tax in Wyoming

Step 1: Determine if you have nexus (physical presence, employees, or over the state's economic nexus threshold — usually $100k in sales or 200 transactions)
Step 2: Register through the state's Department of Revenue online portal (free in most states)
Step 3: Get a sales tax permit / seller's permit number
Step 4: Decide your filing frequency (state assigns based on expected volume)
Step 5: Collect the correct rate — many states are destination-based (rate is buyer's address, not seller's)
Step 6: File returns even on months with zero sales — a 'zero return' is required in most states
