Adjusting your tax return

Adjusting your income tax or corporate income tax return

You can only amend an income tax return or corporate income tax return if you have not yet received a final assessment from the Tax and Customs Administration. Simply modify your old return and send in the new version.
Have you already received a final assessment? If so, you can only pass on a change with the online objection form. You can find this in the secure part of belastingdienst.nl (in Dutch).

Do you think the final assessment is too low? For instance, because your income was higher? If so, you can request an additional assessment in writing.

Adjusting your VAT return

Have you reported too much or too little VAT? If so, you can only adjust the VAT return digitally by submitting a supplementary VAT return. You can do so:

online, using the secure part of the belastingdienst.nl website (formerly login for entrepreneurs; in Dutch only)
using your own software
using your tax advisor’s software

Are you receiving a refund of €1,000 or less, or do you have to pay €1,000 or less? You are allowed to offset that amount in your next VAT return.

Adjusting your payroll tax return

Is your tax return for payroll taxes incorrect or incomplete? If so, you will always have to adjust your tax return. You can find out how to do this (in Dutch) in the Tax Administration Handboek Loonheffingen.
