Note: Washington has no state income tax. Only the Federal Income Tax applies.

Washington is one of seven states that do not collect a personal income tax. However, revenue lost to Washington by not having a personal income tax may be made up through other state-level taxes, such as the Washington sales tax and the Washington property tax.

While Washington collects no personal income tax, it does levy a Business & Occupation Tax on the gross receipts of almost all businesses located in the state. The tax amount varies by industry.
