Corrections Policy

Report an error

Please use the contact form and include:

1. the page URL;
2. the statement or calculation you believe is wrong;
3. the tax year and relevant circumstances; and
4. a primary source, if available.

Do not send a BSN, tax return, payslip, bank statement, or other sensitive personal information.

How we handle corrections

We reproduce calculator issues against the same calculation functions and tests used by the site. Tax-rule reports are checked against the Belastingdienst, Rijksoverheid, legislation, or another appropriate primary source.

Material corrections update the article’s verified or modified date. We distinguish factual corrections from changes caused by a new tax year.

Dutch Tax Calculator provides educational estimates and cannot review an individual tax return or assessment. Contact the Belastingdienst or a qualified tax adviser for personal tax advice.
