About Us

Paybox is a free toolbox of US paycheck calculators. Our mission is simple: help every American worker understand exactly what lands in their bank account — before payday.

What we do

We build interactive salary tools: the flagship 50-state US paycheck calculator, state-specific take-home calculators, and specialist tools for RSUs, overtime, 401(k) contributions, bonuses, and hourly pay conversion. Every tool pairs a live calculator with a plain-English guide.

How our numbers work

Federal figures follow IRS Revenue Procedure 2025-32 (2026 tax brackets and standard deductions). FICA uses the Social Security Administration’s 2026 wage base of $184,500. State taxes use simplified formulas based on each state’s published brackets or flat rates. Full methodology is documented on our US Paycheck Calculator page.

What we are not

Paybox is not a tax preparer, financial advisor, or law firm. Our calculators produce estimates for educational purposes only — not tax, legal, or financial advice. Always verify important decisions with official sources or a qualified professional.

Editorial responsibility

Paybox is an independent publication. Our calculators and guides are researched, built, and verified by our editorial team — every worked example on this site is computed with the same engine that powers the live calculator, and figures are re-checked whenever the IRS publishes annual updates. We do not accept payment to alter results, and advertising never influences our methodology. If you find an error, tell us — verified corrections are fixed promptly.
