On 10 April 2025, the Belgian tax authorities published a new version of the draft Belgian Qualified Domestic Minimum Top-up Tax return (also referred to as QDMTT return) to be submitted by Belgian entities subject to the Belgian law introducing a global minimum tax (or Pillar 2).
This new version is an update of the first QDMTT return published on 18 October 2024. Although the version published on 10 April 2025 is expected to be close to final, it remains provisional until formal publication in the Belgian Official Gazette.
As a reminder, the Belgian QDMTT return should be filed, regardless of whether the transitional CbCR Safe Harbours are met, on an annual basis within 11 months after the last day of the reporting year in scope. For in-scope groups with a financial year aligned with the calendar year, this means the first due date to file the return will be 30 November 2025.
While the information requested in this new draft, applicable to assessment year 2025 (financial years ended between 31 December 2024 and on or before 30 December 2025), is overall slightly lighter, it does not include any major adjustments compared to the first version. Below is an overview of the information to be reported based on the latest draft return:
This section also suggests that the prepayments made for Belgian QDMTT purposes in relation to assessment year 2025 lead to a credit of 12% regardless of when the payments were made. On the contrary, the prepayments made in excess for corporate income tax purposes lead to a credit of 12%, 10%, 8% or 6% depending on the quarter during which these payments were made. Note that the credits are to be offset against (but limited to) the surcharge of 9% of the Belgian QDMTT due.
The Belgian tax authorities noted on their website that the final Belgian QDMTT return as well as further administrative guidance on the return will be published at a later stage. The additional guidance is intended to provide clarification on the data points to be reported in the Belgian QDMTT return as well as further information on the actual filing of the QDMTT return. The XSD scheme is also expected to be released as soon as possible.
As the deadline for the Belgian QDMTT return will be fast approaching and is also very close to the deadline for filing Belgian corporate income tax returns, immediate action is required to ensure that all data points are readily available, initiate data collection and assess whether the transitional CbCR safe harbours can be claimed for Belgium.
We would also be happy to assist with the computation and optimisation of the advance tax payments to be made for assessment year 2026 in relation to Belgian QDMTT and/or IIR (also considering advance tax payments for Belgian corporate income tax) and define your Pillar 2 compliance game plan.
