Draft Turkish Communique on the Implementation of Local and Global Minimum Top-Up Tax (Pillar 2) Has Been Published

In connection with the Domestic and Global Minimum Top-Up Tax (Pillar 2) provisions introduced by Law No. 7524 as Part V of the Corporate Income Tax Law, the Revenue Administration has published, a Draft Communiqué on the implementation of Pillar 2 rules and the template of the Global Minimum Top-Up Tax Information Return (“GIR”) on its official website.

As known, the provisions on Domestic and Global Minimum Top-up Tax and Provisional Articles were added as Part 5 to the Corporate Income Tax Law No. 5520 through Law No. 7524 and entered into force on August 2, 2024, to be applied for the taxation periods starting in 2024 and subsequent years.

Multinational enterprise (MNE) groups with a consolidated annual revenue exceeding 750 million Euros in at least two of the four fiscal years preceding the reporting year, as shown in the consolidated financial statements of their ultimate parent entity, are in scope of Domestic and Global Minimum Top-up Tax.

For entities operating on a calendar-year basis (starting January 1, 2024), the first Domestic Minimum Top-up Tax (“DMTT”) return must be submitted by December 31, 2025, covering resident parent entities and all group entities resident in Turkey.

It is expected that the DMTT return will be made available on the system as of December 1, 2025.

To improve the Draft Communique and contribute to its development, opinions and suggestions may be submitted until Monday, October 27, 2025.

The Draft Communique includes detailed explanations regarding the Domestic and Global Minimum Top-up Tax provisions introduced in the Corporate Income Tax Law No. 5520:

  • Definitions and abbreviations used throughout the Draft Communique are provided in detail. For example, the minimum corporate tax rate is specified as 15%. Low-tax jurisdictions and low-taxed entities are specifically defined within the scope of the Global Minimum Top-up Tax.
  • The Global Minimum Top-up Tax applies to constituent entities of MNE groups whose consolidated revenues, as reported in the ultimate parent’s financial statements prepared in accordance with applicable accounting standards, exceed 750 million Euros in at least two of the previous four fiscal years.
  • The revenue threshold is determined based on consolidated financial statements prepared in accordance with applicable financial accounting standards, covering the four fiscal years preceding the reporting year. Intra-group transactions are eliminated in the consolidation process and are not included in the threshold calculation. Special rules and examples are provided for newly established entities.
  • Group structure and definition of constituent entities are detailed. A group consists of entities under common control reported in the same consolidated financial statements. To be classified as an MNE group, there must be at least one constituent entity or permanent establishment outside the country of the parent entity.
  • Definitions of the ultimate parent entity (“UPE”) and constituent entity (“CE”) are provided in detail. The ultimate parent entity is defined as an entity that has direct or indirect control over one or more other entities and is not itself controlled by another entity. Certain public institutions and sovereign wealth funds are exempt from the rules under specific conditions.
  • Exemptions apply to public institutions, non-profit organizations, pension funds, certain investment funds, and real estate investment funds. Companies meeting specific conditions may also qualify for exemption. A waiver of exemption is permitted under the rules.
  • Income derived from international shipping and related activities may be exempt from taxation under specific conditions. The Draft provides examples demonstrating how such exemptions are applied and how associated expenses are to be calculated.
  • The liability for the Global Minimum Top-up Tax is established based on the rules under the Income Inclusion Rule (IIR) and the Undertaxed Profits Rule (UTPR). Under the IIR, the taxpayer for the Global Minimum Top-up Tax is the ultimate parent entity, intermediate parent entity, or partially owned parent entity located in Türkiye. The Draft provides examples explaining how tax liability is attributed, who qualifies as the taxpayer under the IIR or UTPR, and when such liability arises.
  • Additional tax accrual, tax credit mechanisms, and methods for computing taxes taking into account taxes paid in other jurisdictions are illustrated through comprehensive examples.
  • The Domestic Minimum Top-up Tax applies to members of MNE groups that are fully tax resident in Turkey. The calculation and filing processes will be based on the same accounting periods and standards used for the Global Minimum Top-up Tax.
  • Profit and loss are determined based on financial statements prepared under international accounting standards (including Turkish Financial Reporting Standards/TFRS, as being an authorized accounting standard). Adjustments and calculations related to specific income and expense items are illustrated with detailed examples.
  • The allocation of profits and taxes is regulated in cases where the constituent entity is a permanent establishment, a transparent entity, or a hybrid entity. The rules governing the allocation of covered taxes are also set out in detail.
  • Guidance is provided on how to handle group exits, transfers, and country-by-country computations.
  • Rules for calculating the tax burden, global minimum top-up tax base, and rates are included, with examples for substance-based income exclusion (SBIE) calculated based on payroll and tangible assets.
  • Special provisions are defined for mergers, demergers, share transfers, joint ventures, and specific investment entities such as insurance investment entities.
  • Detailed explanations and examples are included on deductible dividends, distribution-based taxation, deemed dividends, and how these are tracked through specific accounting systems.
  • The filing obligation, the form and content of the DMTT and Global Minimum Top-up Tax returns, filing and payment deadlines, principles of information exchange, and the procedures applicable to filings and payments made on behalf of and for the account of the group are specified.
  • Permanent and transitional Safe Harbour mechanisms (CbCR Safe Harbour, UTPR Safe Harbour, Simplified Calculations Safe Harbour, QDMTT Safe Harbour) are clearly described, along with eligible groups and applicable periods/selections.
  • Transitional provisions include rules on SBIE rates, first filing and payment periods, treatment of prior period losses and tax differences and technical guidance on deferred tax assets and liabilities.
  • The Draft Communique also contains various examples, formulas, and illustrative calculations related to implementation.
