By using TaxCalc you agree to these terms. The short version: the calculators are free planning aids provided as-is, the numbers are estimates that can differ from your real tax liability, and you remain responsible for your own filings and decisions.
The calculators implement published 2026 United States federal tax parameters (IRS Revenue Procedure 2025-32, Social Security Administration wage base announcements) and simplified state models that are identified as estimates on the pages where they appear. They deliberately omit facts a full return would consider — itemized detail, credits we flag as excluded, state exceptions, local taxes, the Alternative Minimum Tax in most scenarios. Results are planning estimates, not tax, legal or accounting advice, and no relationship with a professional advisor is created by using this site. Verify anything consequential with a qualified professional or official IRS resources before acting on it.
The service is provided “as is” without warranties of any kind, express or implied, including accuracy, fitness for a particular purpose and non-infringement. To the maximum extent permitted by law, the operators of TaxCalc are not liable for any loss arising from use of the site — including tax penalties, interest, missed deadlines or decisions made on the basis of an estimate. Figures reflect the law and tables as verified on the date shown in the site footer; tax law and tables change, and past accuracy does not guarantee current accuracy.
The site’s name, design, text and code are the property of its operators. You may quote or link to pages freely (attribution appreciated); bulk reproduction of the calculators or content is not permitted without written permission. These terms may be updated; the effective date is the last-updated date shown at the bottom of this page. Questions about these terms: hello@taxcalc.urbansmartguide.com.
