Worked example

Take a $75,000 gross salary for a single US filer in 2026. A 5% 401(k) contribution ($3,750) and the $16,100 standard deduction bring taxable income down to about $55,150. Federal tax is charged in bands — 10% on the first slice, 12% on the next and 22% on the rest — not 22% on everything. On top of that, FICA takes 6.2% for Social Security and 1.45% for Medicare on the full salary, and a 5% state tax applies. What is left after all of that is your take-home cash.

How progressive tax actually works

The single most common payslip myth is that moving into a higher tax band taxes your whole income at the higher rate. It does not. Tax bands are marginal: only the portion of income that falls inside a band is taxed at that band's rate. That is why your effective rate (total tax ÷ gross) is always lower than your marginal rate (the band your last dollar or pound sits in). A pay rise can never leave you with less money after tax — only the extra slice is taxed more heavily. Pre-tax contributions such as a 401(k) or a salary-sacrifice pension reduce the income that gets taxed, which is why they can be such an efficient way to save.
