Income tax return
The Dutch tax system
If you moved to the Netherlands and paid taxes in your country of origin, you are required to file a migration tax return (also called the M-form) if you are going to work here. You are obliged to arrange that according to the Dutch tax regulations. The Dutch tax office (De Belastingdienst) needs information about you and with the M-form you can provide that to them. Most expats will receive a tax refund because they didn’t live in the Netherlands for the whole year and therefore paid too much income tax. Read more about the M-form here.
