Report an error
If you notice a wrong value or a calculation error, please tell us:
- which calculator you used (the easiest way is the link from “Copy share link”),
- which result you expected and where that value comes from.
We check every report. If we change a value as a result, we record the official source and the date of the check.
What we cannot do
We cannot give individual tax, legal or financial advice. Please do not send us payslips, tax assessments or other personal documents.
How we handle your email is explained in our privacy policy.
