Terms of Use

Last updated: September 18, 2026

Acceptance of these terms

By using this website, you agree to these Terms of Use. If you don't agree with them, please don't use the site.

What this site provides

This site offers free calculators and written guides related to self-employment and 1099 taxes in the United States. The calculators produce estimates based on the numbers you enter and the tax rules programmed into them for the relevant tax year; the guides explain general tax concepts in plain language.

Not tax, legal, or financial advice

Nothing on this site is tax, legal, or financial advice, and using it does not create any professional relationship between you and the operator of this site. Tax rules are complex, change over time, and depend on facts specific to your situation that a general calculator cannot capture. Always confirm your actual tax obligations with a qualified tax professional or the IRS before making financial decisions or filing a return.

No warranty

This site and its calculators are provided "as is" and "as available," without warranties of any kind, express or implied, including but not limited to accuracy, completeness, or fitness for a particular purpose. While tax constants used in the calculators are sourced from official IRS and SSA publications and reviewed for accuracy, some figures — particularly certain state-level figures — may be sourced from secondary references or represent placeholders where official figures were not yet published at the time of writing; these are flagged where known. We do not guarantee that the results are complete, current, or free of error.

Limitation of liability

To the fullest extent permitted by law, the operator of this site is not liable for any direct, indirect, incidental, or consequential damages arising from your use of, or inability to use, this site or reliance on any information or calculation it provides, including any tax underpayment, penalty, or interest that may result.

Advertising and third-party links

This site may display advertisements served by third-party networks, including Google AdSense, and may link to other websites for reference. We don't control, endorse, or take responsibility for the content, accuracy, or practices of any third-party site or advertisement.

Use of this site

You're welcome to use the calculators and read the guides for your own personal or business informational purposes. Please don't scrape, republish, or redistribute the site's content or calculator logic wholesale without permission.

Changes to these terms

We may update these terms from time to time. Continued use of the site after a change means you accept the updated terms. The "last updated" date at the top of this page reflects the most recent revision.
