Afton's retail trade runs on agriculture and ranching), all of it at the 5.000% combined rate. The rate follows the transaction's sourcing, not the storefront's sign — three situations retailers here get wrong:

• In-store pickup vs. delivery: a picked-up order taxes at the store's rate; a delivered order follows Wyoming's sourcing rules to the customer's address
• Store locations near boundary lines: two branches of the same chain can sit in different local-tax jurisdictions — configure POS per location, never per brand
• Returns & exchanges: refund the tax actually charged at sale, even if the rate has since changed

The thresholds that decide it are in the table below; what they do not tell you is that crossing them obliges you to collect at the buyer's local rate, not a state average, which is why Afton and its neighbours have to be priced separately.

Audit & Compliance Warning: Because combined tax rates combine state and local tax components, calculating tax based purely on ZIP codes can lead to errors. Many ZIP codes span multiple municipal boundaries with differing rates. For precise auditing, always use address-level geo-lookup.
