The Wyoming Department of Revenue notes that "The state of Wyoming does not levy a personal or corporate income tax. Wyoming does not impose a tax on intangible assets such as bank accounts, stocks, or bonds either. In addition, Wyoming does not assess any tax on retirement income earned and received from another state. There is no current legislation in the works to create an income tax.        

Corporate Law:

The State's corporations law, based on the American Bar Association's Model Act, minimizes government regulation and maximizes corporate flexibility.  The Wyoming version is even more business-friendly than the Model Act.  Wyoming has three laws, domestication, continuation, and transfer, that allow corporations to move from other states or countries while retaining their corporate identity.

Sales and Use Taxes:  

The sales tax, imposed on retail sales, rentals, and some services, is levied on gross retail sales.  The use tax (4%) is based on the sale price of tangible personal property that is used, consumed or stored in the state.  The base sales tax is 4%, but counties may levy up to two percent additional sales tax.

Property tax:  

All tangible property (except personal property) not specifically exempted is subject to taxation.  The normal rate for commercial and residential property is 9.5% of market value.  Industrial property is usually assessed at 9.5%.  Residential and commercial properties are generally assessed at 9.5 percent of their market value. Industrial property is assessed at 11.5 percent. 

Personal property in transit in interstate commerce and goods manufactured or assembled in Wyoming that will be sent out of state are exempt from property tax.  Pollution-control equipment is exempt, as are trucks and trailers used in interstate commerce and operated by Interstate Commerce Commission permittees.

Workers' compensation insurance rates are very low, far below those in most other states.  Property such as industrial fuels and raw materials, used in manufacturing, compounding or processing of tangible personal property, including containers, cases, and labels, is exempt from sales tax.
