How the Washington estimate works
Enter gross pay for one pay period, federal W-4 adjustments, and the state details shown above. Federal withholding follows Publication 15-T. Washington individual state income tax is zero. When selected, the calculator applies the 2026 Paid Leave employee share of 1.13% × 71.43% up to $184,500 of wages from the employer, plus the 0.58% WA Cares employee premium without that wage cap.
Example: The Paid Leave wage-to-date field applies its annual employer-level cap. WA Cares can be cleared only when an approved or automatic exemption is effective for the paycheck. The calculator does not assume any unentered benefit deduction or invent a tax result.
Weekly, biweekly, semimonthly, and monthly are the supported paycheck frequencies. “Annual salary” is an earnings input and the annual view is a simple period multiplication; neither is an annual payroll-period method. The special Form W-4 adjustment for nonresident aliens is not modeled.
Does Washington have state income tax? Washington does not impose an individual state income tax. Paid Leave and WA Cares employee premiums can still apply in addition to federal withholding and FICA.
