What is IB 1041?
An extension moves the filing date, not the payment. Interest can still run on tax due, so an extension is a way to avoid a late-filing problem rather than a way to pay later.
The form is short, but it has one hard requirement: the request must reach the Belastingdienst before the final filing date of the return. A request that arrives afterwards is too late to help.
Who files IB 1041?
- People who will not have their figures together by the deadline
- Taxpayers waiting on documents from abroad
- Anyone whose adviser cannot file in time and who has no beconnummer arrangement
- People who have had a change in circumstances mid-year
How to fill out IB 1041

- Name the tax year the request covers.
- Say until when you need the extension.
- Print the form, sign it, and post it before the filing deadline.

Frequently asked questions
Can I request this after the deadline?
No. The form is explicit that the request has to be made before the final filing date. After that you are late, and a different conversation starts.
Does an extension stop interest?
No. Belastingrente can still be charged on tax owed, so file as soon as you can even with an extension.
My accountant files for me.
Advisers with a beconnummer have their own extension scheme, which usually gives more time than this form. Ask them first.
