Senate amendments set QMDTT to take effect from the law’s enactment date.
Uruguay’s Senate has confirmed the effective date for the qualified minimum domestic top-up tax (QMDTT) in the 2025–2029 Budget Bill amendments on 3 December 2025.
The Senate-approved amendments establish that the tax will take effect from the law’s enactment date, replacing the previous reference to the parliamentary sanction date. The QMDTT is expected to apply to fiscal years ending 31 December 2025 and beyond, in line with the Executive Branch’s plans.
Following Uruguay’s legislative process, the Budget Bill will return to the House of Representatives for a second approval. Once finalised, the Executive Branch will enact the law and publish it in the Official Gazette.
Earlier, Uruguay’s 2025–2029 Budget Bill, submitted on 31 August 2025, introduced a Pillar 2 Qualified Domestic Minimum Top-Up Tax (QDMTT), known in Spanish as the Impuesto Mínimo Complementario Doméstico (IMCD), and set out the rules for its application.
