PaycheckStates exists because the top paycheck calculators on the internet are lead-generation tools for payroll software — slow pages, sign-up nags, and numbers that are hard to trust because nothing is cited.
We do one thing: fast, accurate, fully-cited take-home pay calculators for every US state, free, with the maths open on every page. Built and maintained by a senior software engineer, every state's calculation is covered by automated tests with hand-computed expected values and cross-checked against major payroll providers before it ships — the full approach is on the methodology page.
The site is funded by unobtrusive display advertising, which is why nothing here asks for your email, your phone number or a “free trial”.
