Know what you actually take home.

Paycheck calculators for every state, federal tax and withholding tools, and the money calculators people use every day. Each one shows its formula, cites the IRS or state source for every rate, and is checked against the 2026 tables.

Why the numbers hold up

Official sources, cited

Federal figures come from IRS Revenue Procedure 2025-32, Publication 15-T and the SSA wage base ($184,500 for 2026). State rates are taken from each state's 2026 schedule via the Tax Foundation's January 2026 dataset and linked on every page.

Tested against the IRS tables

The withholding engine reproduces the 2026 Publication 15-T percentage-method tables exactly; the automated test suite checks it, plus FICA caps and every state's schedule, before any page is published.

Formulas on the page

Every calculator explains the math it uses, shows a worked example produced by the same code, and links to how we calculate. No black boxes.
