How to reach us
What you can write about
Calculator questions
If something in the breakdown isn’t clear — tell us what you entered and the result you expected.
Data corrections
If you think a rate or amount is off, send a correction with its source — nobody has signed the figures off, so a sourced correction genuinely helps.
Suggestions
An idea for a new calculator or a note on the content — we’re glad to consider it.
Note
Please don’t email us personal payslip data — your name, citizen-service number (BSN), or exact amounts. An anonymised example is enough for a rough estimate, and the site neither collects nor stores personal data.
