Washington Tax Tables
Washington Tax Tables provide a complete reference of how state income tax is calculated for each supported year. These tables summarise the official rules issued by the Washington Department of Revenue and present them in a clear structure that matches the calculations used in our Washington Tax Calculator. They are useful for checking withholdings, estimating liability, reviewing historical tax years and understanding how state policy shapes taxable income.

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.
What Is Contained in the Washington Tax Tables?
Each tax-year page provides a structured summary of the components Washington uses to calculate individual income tax. While details vary by year, the state tax tables generally include the following elements:
- Retirement income rules including partial or full exemptions for pensions or Social Security.
Together, these elements provide a transparent breakdown of how Washington calculates tax for each year. This structure helps taxpayers review year-to-year changes, employers validate payroll withholding and financial planners analyse how Washington’s rules differ from federal requirements. All values shown in our Washington Tax Tables match the official figures published by the state.
Frequently Asked Questions

What if I move to a wage-tax state mid-year?
Use the other state’s page for the taxed portion and this page for WA months. Compare in the State hub to plan withholding.
Student loan interest—does it change my net?
