Terms of Use

By using this site you accept these terms. They are deliberately short.

Use the calculators as often as you like, for yourself, your household or your employees. Link to any page. Quote a reasonable extract with attribution and a link back.

What you may not do

Scrape or republish the content wholesale, present our calculations as your own product, or attempt to interfere with the operation of the site.

No warranty

The calculators and content are provided as they are, without warranty of any kind. Tax law changes, states publish corrections, and payroll systems differ. We work to keep everything current and we document our sources on the methodology page, but we cannot guarantee that every figure matches your employer's calculation.

Limitation of liability

To the fullest extent permitted by law, we are not liable for any loss arising from reliance on figures produced by this site. Verify anything material with your employer, your payroll provider or a qualified tax professional before acting on it.

We may update these terms. Continued use after a change means you accept the revised version.
