This lesson provides an in-depth examination of the QDMTT, its function as the primary line of defence for source jurisdictions, its design features, and its interaction with the IIR and UTPR.

-
Definition and Purpose:Â A QDMTT is a Domestic Minimum Top-up Tax (DMTT) that meets the qualification criteria established by the OECD/G20 Inclusive Framework on BEPS. A DMTT is the domestic implementation of the Pillar Two rules, allowing a jurisdiction to claim primary rights to impose top-up tax over any low-taxed profits in that jurisdiction. The QDMTT is designed to protect the primary taxing rights of source jurisdictions over low-taxed profits.
-
Rule Order and Crediting:Â QDMTTs apply before qualified IIRs and the UTPR. If a jurisdiction’s DMTT is categorised as a QDMTT, the top-up tax imposed by the source jurisdiction under the QDMTT can be claimed as a tax credit in the calculation of top-up tax under the IIR in the parent entity jurisdiction. If the QDMTT fully collects the top-up tax, the parent jurisdiction loses its right to impose top-up tax under the IIR.
-
The QDMTT Safe Harbour: Recognition of qualified status is important for determining the order in which global minimum tax rules apply. If a DMTT meets specific criteria, it can fall under the QDMTT Safe Harbour, exempting that jurisdiction from IIR and UTPR application. The QDMTT Safe Harbour prevents MNE Groups from making the Pillar 2 calculation twice—once on jurisdictional level and once on a more global level.
-
The “Switch-Off” Rule:Â The Switch-off rule prevents a taxpayer from claiming the benefit of the QDMTT Safe Harbour when certain aspects of the local QDMTT render it inapplicable to one or more of the MNE Group’s constituent entities within that jurisdiction. In such cases, the QDMTT continues to function as a credit against IIR/UTPR top-up tax liability rather than providing safe harbour protection.
