Washington State Tax Guide (2026)
Washington has NO ordinary individual income tax. It levies a 7% excise tax on LONG-TERM capital gains above a per-person exemption (~$270,000 for individuals, indexed). Community property state. WA has a state estate tax. No QSBS conformity applicable (no income tax).
Why it matters: State income tax is only part of the picture. Residency, sourcing of income, credits, and local taxes change the effective burden. Use the state income tax estimator for a number, and check reciprocity and convenience-rule status before a move or remote-work arrangement.
This guide summarizes structural facts for planning. It is not a substitute for the official Washington tax code or a licensed preparer.
