The progressive nature of federal taxes ensures that higher earners contribute a larger share of their income to the federal budget.

State Income Tax

A significant benefit for residents of Washington is the absence of a state income tax on wages. Washington state does not have an individual or corporate income tax on earned income. This policy allows individuals to retain more of their earnings compared to residents of states with income taxes. The lack of a state income tax is a major factor that attracts businesses and individuals to the state.

Local Taxes

While Washington does not levy a state income tax on wages, local tax obligations vary depending on the municipality. The primary form of local taxation is sales tax, which can vary significantly from one city to another. For instance:

• The state sales tax rate is 6.5%. Combined with local rates, total sales tax generally ranges from 7.0% to 10.4% depending on the jurisdiction.
