Terms of Use

Last updated: October 11, 2026

By using Paybox, you agree to these terms.

Estimates only — not professional advice

All calculators on this site produce estimates for educational and informational purposes only. They are not tax, legal, or financial advice. Federal figures follow IRS publications and state figures use simplified formulas that exclude credits, local taxes, and individual elections. Always verify important decisions with official sources or a qualified tax professional.

Acceptable use

Use the site lawfully and responsibly. Do not attempt to disrupt the service, scrape content at abusive rates, or misrepresent the site’s output as professional advice.

Intellectual property

Calculator designs, text, and guides are the property of Paybox unless otherwise noted. You may link to our pages; reproducing substantial content requires permission.

External links

We link to official sources such as the IRS and state tax agencies for your convenience. We are not responsible for the content or accuracy of external websites.

Service availability

We aim to keep Paybox available and accurate, but we do not guarantee uninterrupted access or error-free calculations. Figures are updated when tax authorities publish annual revisions.

Limitation of liability

The site is provided “as is” without warranties. To the maximum extent permitted by law, Paybox is not liable for decisions made based on its estimates.

Governing law

These terms are governed by the laws of the United States, without regard to conflict-of-law principles.

Changes

We may update these terms; continued use constitutes acceptance.
