How to start filling out your M-Form

Next steps.

We will inform the Belastingdienst that we will be your tax consultant for the fiscal year 2021. We will need your full name and address and BSN-number. You can find all this information on the dutch salary slip.

Download our checklist for 2021 in order to gather all info required for your form.  When we receive your information and checklist, we can start filling out your tax form immediately. We will contact you in case additional information is required.

Sometimes the Belastingdienst will respond by sending you the dutch form -registratie machtiging intermediair- .  With a special code on this letter, we have access to your data of 2018 that is already registered by the Belastingdienst. This is additional information we use to confirm the info you provided.

Requesting a postponement.

Please inform us if you need a postponement for your tax application for 2021. We can apply for it in most cases, even after the due date on the letter received from the Belastingdienst has passed.
If we require additional information, please use our use our contact form
