M Form 2019
If you have only lived in the Netherlands for part of the year, because you immigrated to the Netherlands or emigrated from the Netherlands in 2019, you must file a tax return using the M Form.
You are required to file your return before the deadline stated on the return form. If you need more time, you may apply for a postponement.
If you did not receive an M Form and you wish to file a tax return for 2019, you can apply for an M Form online. Unfortunately, you cannot file this particular tax return online.
