Can You Write Off Washington state income tax?
Short answer: Washington has no tax on wages, but it taxes long-term capital gains above a large threshold, and its sales tax is among the highest.
No state income tax means nothing to deduct for state income tax on your federal return, but sales and property taxes can still count toward the SALT deduction if you itemize.
Records to keep: Keep receipts, statements (1098, 1098-T, 1099, W-2G), and a note of what each cost was for. Compare itemizing to the 2026 standard deduction before you claim.
