Wyoming Sales Tax Rate (2026)

Wyoming imposes a statewide base sales tax rate of 4%. Wyoming is a destination-based sales tax state, meaning the tax rate is determined by the buyer's delivery address.

County taxes: Wyoming counties can levy additional sales tax on top of the state rate, and rates vary by county.

City taxes: Cities in Wyoming may impose their own sales tax, adding further variability to combined rates.

Special district taxes: Special taxing districts (transit authorities, improvement districts, etc.) in Wyoming can add additional taxes that apply within their boundaries.

Rates in Wyoming are typically updated quarterly. Businesses should monitor rate changes regularly to maintain compliance.

The combined sales tax rate a customer pays in Wyoming depends on the specific jurisdiction of the transaction. Local governments use sales tax revenue to fund essential services such as infrastructure, public safety, and education.

This means that two addresses within the same city may have different tax rates if they fall in different special taxing districts. ZIP codes are particularly unreliable for tax determination because a single ZIP code can span multiple counties or tax jurisdictions.

For businesses operating in Wyoming, manually tracking these rate changes across every jurisdiction is impractical. An automated API solution ensures you always apply the correct rate at the point of sale, reducing compliance risk and audit exposure.
