Acceptance of terms
By accessing or using CalcSumly (calcsumly.com), you agree to be bound by these Terms of Service. If you do not agree to these terms, please do not use this site.
Description of service
CalcSumly provides free, browser-based calculators designed to help US freelancers and self-employed individuals understand their potential tax obligations. All tools are provided at no cost and without registration. We reserve the right to modify, suspend, or discontinue any part of the service at any time without notice.
No professional advice
The calculators, articles, and all other content on CalcSumly are provided for educational and informational purposes only. They do not constitute financial, legal, or tax advice and do not create a professional relationship between you and CalcSumly or any of its contributors.
Tax laws change frequently and may vary based on your specific circumstances. Always verify results with the official IRS or SSA publications cited on each tool, and consult a licensed CPA, enrolled agent, or tax attorney before making financial decisions.
Accuracy and limitations
We make reasonable efforts to keep tax figures current and accurately cite their sources. However, we make no warranties — express or implied — regarding the completeness, accuracy, or fitness for a particular purpose of any calculator output. Results are estimates based on the inputs you provide and the tax year constants shown; they may differ from your actual tax liability.
Limitation of liability
To the fullest extent permitted by applicable law, CalcSumly and its operators shall not be liable for any direct, indirect, incidental, special, consequential, or punitive damages arising from your use of — or inability to use — this site or its calculators, including any errors or omissions in calculator outputs.

Personal, non-commercial use is permitted. You may not reproduce, redistribute, or create derivative works from this content for commercial purposes without written permission.
