Report cross-border tax arrangements (Mandatory Disclosure Rules/DAC6)
As a result of the Dutch implementation of the European Directive Mandatory Disclosure Rules (MDR)/DAC6 intermediaries and/or taxpayers must report potentially aggressive cross-border tax arrangements to the Netherlands Tax and Customs Administration. These are tax arrangements involving residents of different countries and which could possibly be used to avoid taxation.
Are you responsible for reporting cross-border tax arrangements?
You can file a report via the data portal of the Netherlands Tax and Customs Administration. It is also possible to correct a filed report. How to correct a filed report is explained in the 'User instruction guide DAC6 data portal'. You can find the user instruction guide on this page under 'Where can I find more information?', under 'Useful links’.
To log on to the data portal you need eHerkenning level 3 or higher. Apply for eHerkenning well in advance via the eHerkenning website. Select 'Gegevensportaal Belastingdienst' when applying for eHerkenning. Do you want to file a report but is eHerkenning not available to you, for example because you are a private person? Then you can register for a username and password via the data portal. If you have questions about logging on to the data portal, please contact the contact center.
- Which arrangements need to be reported?
Cross-border arrangements that meet one of the hallmarks must be reported. You will find a list of these hallmarks in the DAC6 Directive. For a number of hallmarks, you only need to report the arrangement if the most important benefit (or one of the most important benefits) of the arrangement is gaining a tax advantage.
In the checklist you'll find a short overview of the hallmarks.
Guidance on cross-border arrangements subject to mandatory disclosure is available. In this guidance you find amongst others examples of arrangements subject to mandatory disclosure for each hallmark.
- Who files the report?
If you are involved as an intermediary in a cross-border arrangement that must be reported, you are responsible for reporting it. There are two exceptions to this rule. You are not required to report the cross-border arrangement subject to mandatory disclosure in the following cases:
- Another intermediary has already reported the arrangement. And this intermediary has given you a reference number as proof.
- You have a legal professional privilege.
The DAC6 Directive applies to all intermediaries. For example: tax advisers, lawyers, accountants, civil-law notaries, financial advisers, banks and trust offices.
The taxpayer for whom a cross-border arrangement is intended must report it himself in the following cases:
- Only an intermediary from outside the European Union is involved in the arrangement.
- The intermediary involved in the arrangement has invoked his legal professional privilege, and is therefore not required to do so.
- No intermediary at all is involved in the arrangement.
Are you not sure if anyone else involved in the arrangement has already reported it? When in doubt, report the arrangement yourself.
- What happens if you fail to report?
In that case you risk a substantial fine.
- When do you have to report?
For cross-border arrangements in which you are involved as from 1 January 2021, you must always report within 30 days.
The DAC6 Directive also has retroactive effect.
On 28 February 2021 at the latest, you are therefore required to have reported the cross-border arrangements you are involved in from 25 June 2018 to 1 July 2020.
For reportable cross-border arrangements in which you are involved from 1 July 2020 to 1 January 2021 (the transitional period), you have reported 31 January 2021 at the latest.

- What will happen to your disclosure?
Once you have reported a disclosure we will send you a reference number.
We forward your disclosure to a European database which is accessible to the tax authorities of the European Member States. In addition, we use the information from your disclosure within the Netherlands Tax and Customs Administration for supervisory purposes, for example.
