Belgian DAC6/MDR Submission Process

On 23 November 2020, the Belgian Tax Authorities published guidance on the technological requirements of the DAC6/MDR reporting. The published documents include the MDR-DAC6 BE Scheme User Guide and the Validation Rules. The User Guide describes the electronic form “MDR-DAC6 BE Scheme” which must be used by the intermediary or the relevant taxpayer for reporting and explains which information must be included in the form. In order to file a valid reporting, the reporting person must comply with the principles described in the guide and also take into account the Validation Rules to guarantee the quality of the filed information.

The MDR-DAC6 BE Scheme User Guide and the Validation Rules are published in English and are available on the website of the Belgian Tax Authorities via this link.

What is the DAC6-submission process?

The DAC6-reporting in Belgium is based on the submission of an XML-file. The Belgian XML-scheme is designed by the Belgian Tax Authorities based on internationally agreed specifications whereby a number of national validation rules apply for the generation of the XML-file. As soon as an XML-file is generated, it can be submitted via the webportal “MyMinfin “. This submission process requires a permission right (“Role”) setup. After submission, the Tax Authorities will verify if the XML-file satisfies the requirements, with the help of the validation rules. When the XML-file is validated, the Tax Authorities will send a delivery receipt, including the identification references attributed to the new arrangement and/or new reporting. In case the XML-file is not valid, a failure report will be sent to the submitter.

What are the first submission deadlines?

The DAC6 legislation provides for the mandatory reporting of reportable cross-border arrangements by intermediaries and relevant taxpayers to the tax authorities within 30 days. The legislation is effective as from 1 July 2020, but due to the 6-months deferral of the reporting obligations, the following deadlines apply for the submission of the first reports:

  • reportable cross-border arrangements of the transitional period (i.e. where the first step in the implementation is made between 25 June 2018 and 30 June 2020) must be reported by the latest by 28 February 2021;
  • reportable cross-border arrangements that have been made available for implementation, or are ready for implementation, or where the first step in the implementation has been made in the period between 1 July 2020 and 31 December 2020, must be reported by 30 January 2021 (i.e. within 30 days staring on 1 January 2021);
  • the first periodic report for marketable arrangements must be submitted by 30 April 2021.
