This is our primary and preferred contact method for all inquiries. To help us respond quickly, please include a clear subject line and, where relevant, the full URL of the page you are writing about.
We aim to reply within 2 to 3 business days. Reports of incorrect calculations are prioritized and usually handled sooner. Privacy and data requests are handled within the timeframes required by applicable law, as described in our Privacy Policy.
This is the most valuable message you can send us. If a result looks wrong, or if a tool is using last year's tax brackets, contribution limits, or mileage rate, let us know. Please include:
Use the subject line "Calculation Error" so it reaches the right place immediately.
If a tool will not load, a button does not respond, a PDF or CSV export fails, or the layout breaks on your device, tell us. Please include your browser and version, your device type, and what you were doing when the problem occurred.
If there is a calculation you keep doing by hand, or a US-specific problem you cannot find a decent free tool for, describe it. Reader suggestions directly shape what we build next.
Beyond the math itself, if an explanation, a state-specific rule, a deadline, or a described process is inaccurate or out of date, we want to fix it. Please point to the specific sentence and, where possible, the correct source.
For advertising, sponsorship, partnership, or media inquiries, email us with "Business Inquiry" in the subject line. Please note that we do not accept paid placement within tool logic, calculation results, or our explanatory content.
