Washington has no state income tax. On $120,000 that is worth roughly $6,000 a year compared with a typical 5% flat-tax state, and considerably more against California or New York. The state does collect WA Paid Family & Medical Leave ($792 a year) and WA Cares Fund ($696 a year) from employees, which is why the state line is not quite zero.
Seattle does not levy a municipal income tax, so the local line on your pay stub is zero — the only layers are federal, FICA.
The federal bill is $17,570. After the $16,100 standard deduction, $103,900 of taxable income runs through the 10%, 12%, 22% brackets; the marginal rate is 22% but the effective federal rate on gross pay is 14.6%. Every extra dollar of pre-tax 401(k) contribution at this salary saves 22 cents federally.
FICA is the flat layer: 6.2% Social Security plus 1.45% Medicare on every dollar, $9,180 in total. Unlike income tax it is not reduced by the standard deduction or by a 401(k) contribution — only pre-tax health, dental and FSA premiums under a Section 125 plan escape it.
How a 401(k) changes the monthly number
Each dollar deferred costs less than a dollar of cash flow because it leaves before income tax. The gap between "contribution" and "cash-flow cost" is your immediate tax saving.

How this audit was computed
The figures above are produced by a deterministic tax engine, not a survey. Gross pay is reduced by the 2026 federal standard deduction and run through the seven federal brackets; FICA is applied to wages with the Social Security cap and Additional Medicare threshold; Washington's lack of an income tax is applied next. Rent is a median asking price for a 1-bedroom, refreshed quarterly.
Assumptions: single filer, standard deduction, no dependents, no itemized deductions, no bonus or equity, employer-side taxes excluded. Actual withholding on a pay stub depends on Form W-4 elections and pay frequency; year-end liability is what is shown here. Read the full methodology or report a correction.
