Washington Paycheck Calculator

No income tax, but not an empty pay stub

Washington levies no personal income tax on wages, which is a significant part of what makes Seattle-area compensation competitive. But Washington is not Texas or Florida: the state funds two social-insurance programmes through premiums withheld directly from employee wages, so your stub does carry state lines.

Paid Family and Medical Leave and the WA Cares Fund both take a small percentage of wages. Neither is an income tax — they buy defined benefits, paid family leave and a long-term care benefit respectively — but both reduce take-home pay, which is why the estimate above includes them rather than pretending Washington is a zero-deduction state.

How the state programmes differ from a tax

PFML premiums are split between employer and employee and apply up to the Social Security wage cap, so higher earners stop contributing partway through the year. WA Cares applies to all wages with no cap at all, which means it keeps taking a slice of every paycheck no matter how much you earn — the opposite shape to most payroll deductions.

That difference matters for high earners. As the year progresses, Social Security and PFML both switch off at their caps while WA Cares does not, so your late-year paychecks are larger than your early-year ones but not as much larger as you might expect.

Equity compensation in the Seattle market

A large share of Washington's technology and aerospace workforce receives a meaningful part of total compensation as restricted stock rather than salary. RSUs are ordinary income when they vest, valued at the vesting-day price, and they are typically withheld at the flat federal supplemental rate.

For anyone whose marginal rate exceeds that flat supplemental rate, this under-withholds — and because the shortfall scales with the size of the vest, it can be substantial. The calculator above models salary; treat vesting income as additional ordinary income on top, and consider extra W-4 withholding in a heavy vesting year.

Planning around Washington's structure

The state premiums are effectively fixed, so the lever you control is federal. Pre-tax 401(k) and HSA contributions reduce federal taxable income, and Washington imposes nothing that offsets the benefit.

Washington also relies heavily on sales tax, with high combined rates in the Puget Sound area. As with Tennessee, the no-income-tax headline is genuine but partial — it favours savers over spenders, and none of it appears on your pay stub.

How Washington taxes your paycheck

Washington has no state income tax on wages, though it withholds WA Cares and Paid Family & Medical Leave premiums. Use the calculator above to estimate your take-home pay after all withholdings.

Every US paycheck also has federal income tax, Social Security (6.2% up to the annual wage base), and Medicare (1.45%, plus 0.9% on high earners) withheld. Your taxable income is your gross pay minus pre-tax deductions such as 401(k) and pre-tax health premiums.

Washington has no income tax, but most workers see WA Cares Fund and Paid Family & Medical Leave premiums withheld from their wages. These are modelled here as a single estimated payroll premium.
