Tax = Price × 4 ÷ 100 Price before tax = Total ÷ 1.04

| Sales tax at 4% | $10.00 |
| Total | $260.00 |

Selling to Wyoming from another state
Since the 2018 South Dakota v. Wayfair decision, states can require out-of-state sellers to collect sales tax once their sales into the state pass an economic nexus threshold, even without a physical presence. Marketplaces such as Amazon and Etsy usually collect and pay the tax for sales made through them. Check the Wyoming revenue department for the current threshold and registration steps.
