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
Capital-gains distributions—do they affect this Washington wage view?
They affect your federal tax and AGI; wages here are unchanged. Washington has a capital-gains excise that isn’t a wage tax and isn’t computed on this page—handle gains via Schedule D, then address any WA excise separately.
Is overtime taxed differently in Washington?
Overtime is ordinary wage income—federal and FICA/Medicare only. Washington has no wage income tax to layer on top.
HSA/FSA pre-tax in Washington?
Pre-tax HSA/FSA contributions reduce federal wages, increasing net pay (and sometimes FICA impact), even without state wage tax.
I’m a nonresident working remotely from Washington for an out-of-state employer—do I owe state wage tax?
Washington does not tax wage income. Taxation in another state generally depends on where you physically perform work (and that state’s nexus rules), not just employer location.
