Our principles

• Official sources only. Rates, brackets and limits come from the IRS, the Social Security Administration and state agencies, and each page links to them.
• Tested before publishing. Every update must pass the official worked examples, independent hand calculations, form-wiring checks and a cross-check against independent third-party calculators.
• Dated. Every calculator shows the date its figures were last verified.
• Private. Calculations run in your browser.

Our results are estimates for information only and are not tax, legal or financial advice. Read the methodology to see exactly how each number is produced.
