Email TaxCalcTool
[email protected] is our inbox for corrections, accessibility feedback and questions about the site.
Report a calculation or content issue
Include the page address, country, tax year and the result you expected. If possible, link to the official rule or guidance that explains the difference. A rounded, invented example is enough to reproduce most problems.
Please do not send tax identification numbers, returns, payslips, bank details or other sensitive documents. We do not need your personal financial records to investigate a software issue, and this inbox does not provide individual tax advice.
For educators and publishers
You can link directly to a country calculator, explanation or official-source entry. Keep the country, year and calculation scope with any example you share: several tools calculate bracket tax before credits, rather than take-home pay. If you are preparing a classroom resource, tell us the topic and audience so we can point you to the relevant explanation.
How corrections are handled
We check the cited evidence and whether the case is within the calculator’s supported scope. Material rule changes need verified sources and reference calculations before release. See our content and correction policy, source register and published updates.
