The Belgian tax authorities Federal Public Service (SPF) announced that the prepayment system for the Domestic Minimum Top-Up Tax (DMTT) and Income Inclusion Rule (IIR) top-up tax was activated on 2 September 2024.

Taxpayers who prepay these taxes by 20 December 2024 can benefit from the related prepayment tax reductions. These groups can make their advance payments for the year 2024, provided they have their company number obtained after notification.

However, such prepayments are limited to groups registered for Pillar Two minimum taxation in Belgium.

The initial registration deadline for groups intending to prepay was 15 July 2024.

Earlier, Belgium’s Ministry of Finance published the Royal Decree of 7 July 2024 in the Official Gazette on 16 July 2024.

This Decree establishes the guidelines for companies to make advance payments towards the minimum tax under Belgium’s Pillar Two global minimum tax regulations. This applies to large multinational and domestic businesses that have generated over EUR 750 million in revenue in two of the last four years.

The Decree also states that advance payments must be made to the financial accounts of the “Collection Centre – Advance Payments Service” via payment or transfer.

Taxpayers should submit requests for rectification, reimbursement, or postponement of advance payments through the MyMinfin platform.
