A question about the site, a mistake you spotted or a partnership idea? Write to us.
What to write to us about
- Errors in calculations — if a result does not match your payslip or tax assessment, tell us which calculator and figures you used;
- Suggestions — new calculators, guides or improvements;
- Partnerships and advertising — collaboration or advertising proposals.
We do not give personalised tax advice. For your specific case, contact the Tax Authority, Social Security or a certified accountant.
What to include
For a calculation, tell us the calculator, tax year, region and the figures you entered (rounded is fine — we do not need personal data or your NIF), and what result you expected and where it came from.
Response time
We read every message and usually reply within a few working days.
