Turkey Issues a Draft Communique for Detailed Pillar 2 Implementation

On October 3, 2025, Turkey published the Draft Communique on the Minimum Tax Law, and the Draft GIR, for consultation. Whilst Turkey has enacted its Minimum Tax Law, a lot of the detailed application of the GloBE rules was left to a further Regulation. 

This Communique therefore provides for the detailed rules for the implementation of the GloBE rules in Turkey.

The Law includes an income inclusion rule (IIR), an under-taxed profits rule (UTPR) and a domestic minimum tax (intended to be a Qualified Domestic Minimum Top-Up Tax (‘QDMTT’)).

Although the Law provides that it will apply to profits arising in 2024 and subsequent fiscal years, Article 50 provides that the UTPR aspects are to apply from January 1, 2025.

Key Aspects of the October 2025 Draft Communique include:

OECD Administrative Guidance

Aspects of the First Set of OECD Administrative Guidance included in the Law are:

-Debt release Election (Article 2.4)

-Equity Gain or loss inclusion election (Article 2.9)

The only aspects of the Second Set of OECD Administrative Guidance included in the Law are Marketable Transferable Tax Credits (aside from the Transitional UTPR Safe Harbour). As such the additional rules for the substance-based income exclusion and currency conversion rules are not included. No aspects of the Third or Fourth Set of OECD Administrative Guidance are included in the Law.
