How Washington Calculates Income Tax
Washington uses a progressive tax system where income is divided into brackets and each portion is taxed at its marginal rate. These rules determine how wages and other taxable income are assessed for Washington returns, with updated tables released each year to reflect legislation and inflation changes. For a broader explanation of how tax tables work, see our Tax Tables guide.
