Candy is considered food and is generally exempt unless sold from a vending machine. Candy from a vending machine is considered to be designed for immediate consumption and is therefore taxable.

Wyoming imposes sales tax on the retail sale or lease of tangible personal property, admissions fees, and some services. As a Streamlined Sales Tax state, Wyoming encourages businesses without a sales tax obligation to register with the state and collect.

How to Register

Applications for sales and use tax licenses are available at the Wyoming Department of Revenue website. Online registration is also available.

Businesses selling into multiple states may register with the Streamlined Sales Tax Project.

How to File and Pay

Online filing of sales and use tax returns is available.  Paper sales and use tax returns may also be downloaded and submitted to the department. Vendors are required to remit sales tax returns even when no sales were made during the filing period.

  • Businesses collecting up to $150 in tax per month file quarterly returns.
  • Businesses collecting more than $150 in tax per month file monthly returns.
