Report cross-border tax arrangements (2024)

• Read this information in Dutch

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 Administration. These are tax arrangements involving residents of different countries and which could possibly be used to avoid taxation.

Reporting cross-border tax arrangements

You can file a report on the data portal of the Netherlands Tax Administration. It is also possible to correct and to partially or fully delete a previously filed report. In the 'User instruction guide DAC6 data portal' you can read how and in which cases to file, to correct or to partially or fully delete a report.

More about reporting cross-border tax arrangements

• 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 flowchart 'MDR/DAC6: van melding tot toezicht' ('MDR/DAC6: from filing a report to supervision', only available in Dutch) you'll find a short overview of the hallmarks.

  There is also the 'Leidraad meldingsplichtige grensoverschrijdende constructies' ('Guidance on cross-border arrangements subject to mandatory disclosure', only available in Dutch). 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.

  Please note!

  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.

  • This infographic tells you when you need to take which steps to be well prepared for the mandatory disclosure of cross-border arrangements.

• 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 1January2021, you must always report within 30days.

  The DAC6 Directive also has retroactive effect.

  On 28February2021 at the latest, you are therefore required to have reported the cross-border arrangements you are involved in from 25June2018 to 1July2020.

  For reportable cross-border arrangements in which you are involved from 1July2020 to 1January2021 (the transitional period), you have reported 31January2021 at the latest.
