What's in the Wyoming rate file
Wyoming data ships inside every edition — we do not sell single-state files. Each row carries the ZIP code, county and city name, the rate at each jurisdiction level, the combined total, and whether shipping is taxable. The higher editions add district reporting codes, FIPS codes, effective dates and sales tax holiday windows.

How local tax works in Wyoming. State-collected. County optional sales and use tax and county and municipal lodging taxes are voter-approved at county level but collected by the Excise Tax Division on a single state return.
Worth knowing. Rates vary only by county, so there are just 23 jurisdictions to track — but there is still no address-level lookup tool, so you work from the Master Rate Charts or the ZIP-code rate spreadsheets.
Questions
Wyoming sales tax questions
What is the sales tax rate in Wyoming?
The statewide base rate is 4%. Local jurisdictions add their own rate on top, so the rate you must actually charge is almost never the state rate.
Is shipping taxable in Wyoming?
Generally no. In Wyoming a delivery charge is not taxable, and combining it with handling does not make it taxable.
That distinction catches people out, which is why our file carries both flags — TAX_SHIPPING_ALONE and TAX_SHIPPING_AND_HANDLING_TOGETHER — on every row, for the specific jurisdiction. Your system doesn't have to encode the rule.
How many sales tax jurisdictions are there in Wyoming?
We track 25 bodies that actually levy a sales tax in Wyoming — 21 counties and 4 special districts — across 194 WY ZIP codes. We count a county, city or district only where it charges something, not merely because it appears in the file.
