Global Minimum Tax (GMT) Services

Navigating Global Tax Rules with Precision, Insights and Confidence

Overview

 

Global tax rules are shifting fast. With the enactment of PMK 136/2024, Indonesia officially enters the era of the Global Anti–Base Erosion (GloBE) Rules, including the Qualified Domestic Minimum Top-Up Tax (QDMTT) and other mechanisms that impact multinational groups with consolidated revenue of ≥ EUR 750 million.

 

For businesses operating in Indonesia, GMT is no longer a “wait and see” issue. It is a compliance obligation, a strategic tax matter, and a global competitiveness concern.
DDTC stands at the forefront to guide you through all of it.

Why GMT Matters Now

 

GMT affects more than your tax bill. It alters:

  • Global effective tax rates (ETR)
  • Intercompany pricing, incentive planning, and supply chain structures
  • Internal controls and data systems
  • Stakeholder expectations—from headquarters to regulators

Key Message

 

Indonesia’s adoption of QDMTT means local entities may face top-up tax even when parent jurisdictions apply transitional relief or side-by-side systems.

 

In other words: GMT will continue to create tax implication for entities in Indonesia
