Worldwide income return
The Opgaaf wereldinkomen form decides the final amount of your Dutch benefit or CAK healthcare contribution. The Belastingdienst sends it after a year you spent partly or fully outside the Netherlands. It applies if you, your partner, or a relative had a Dutch benefit or paid the CAK healthcare contribution abroad. The CAK is the Dutch agency that collects the healthcare contribution abroad. It is not an income tax return, but it is mandatory.
We check your situation and file it before the deadline. Helping a parent or relative abroad with theirs? We handle that too.
Whether you count as a Dutch tax resident is on our page about tax residency.

The difference is the check, not the form. Ignore the form and the Belastingdienst sets your worldwide income itself, usually to your disadvantage.

We file your form before the date on the cover page or request a postponement if you need more time.
You agree to a fixed fee in writing before any work starts. The number of years and family members involved sets your fee, and we tell you up front. Filing a Dutch tax return this year too? Ask about combining both. Read how our Dutch income tax return service works.
“Most people worry when this form lands. It's usually simple once we know your situation abroad and in the Netherlands. We just need the details, once.”

Reviews
Menno has been a great help, always on top of the next steps in the process, and we greatly appreciate his efforts and expertise.
Pleasant communication with Bram! Quick answers to our questions, and after uploading our documents an online conversation to go through our tax return.
Nadya was very helpful and responsive, the process ran smoothly and now the last step is to wait for the provisional tax assessment from the belastingdienst :-) 10/10!
