Washington Paycheck Tax Calculator: How Washington Payroll Works
A Washington paycheck calculator is really a federal
calculator with Washington pay rules on top. Your stub should show
federal income tax, Social Security, Medicare, WA PFML and WA LTC
(WA Cares), and nothing for
state withholding (SIT).
Our
pay stub abbreviations list
explains the codes you'll see.
Federal Withholding for Washington Paychecks
Federal withholding uses your Form W-4 and the 2026 federal
brackets. The calculator supports filing status, Step 2(c), Step 3
credits and Step 4(a), 4(b) and 4(c). If you claim the new overtime
or tips deductions, our
W-4 Step 4(b) worksheet guide
shows how to enter them, and our
2026 federal tax withholding guide
covers the rest. For tipped restaurant and hospitality workers, the
new federal tips deduction can make a real difference.
Working Across State Lines
Washington residents who work in
Oregon
or Idaho
owe that state's tax on those wages, which matters for the many
Vancouver residents who commute to Portland. Oregon and Idaho
residents working in Washington owe no Washington income tax, but
their home state taxes the wages, and they can apply for a WA Cares
exemption as out-of-state residents.
Washington's New High-Earner Tax
In March 2026 Washington passed a 9.9% tax on individual income
over $1 million, starting with the 2028 tax year. It's expected to
be challenged in court and doesn't change 2026 paychecks.
Bonuses
Only federal taxes apply to Washington bonuses. A bonus paid separately
usually gets a flat 22% federal withholding plus FICA. See
why bonuses are taxed so high.
Why Your Actual Washington Paycheck May Differ
This calculator is a close estimate, not your employer's payroll
run. Your W-4 on file, benefit elections, overtime hours,
year-to-date wages and a 27th biweekly payday in some years can all
move the result a little.
Three-paycheck months
change monthly cash flow but not the tax on each check. For a full
checklist, see why your paycheck is lower than expected.
At year-end, our W-2 form generator
can use the same totals.
