Foreign Subsidiaries in Turkey: How the New "Local Minimum Tax" Impacts Your Bottom Line

If you are operating a subsidiary in Turkey as part of a large Multinational Enterprise (MNE) with consolidated revenues exceeding €750 million, the tax landscape has just shifted significantly.
Turkey has introduced the Local Minimum Complementary Corporate Tax (Domestic Top-up Tax) as part of its alignment with the OECD's Pillar 2 rules. While much of the local discussion confuses this with domestic regulations, for foreign investors, the message is clear: The era of effective tax rates below 15% due to incentives is coming to an end, but the tax revenue will now stay in Turkey.
Here is what foreign subsidiaries need to know based on the latest insights from the Tax Inspection Board.
1. The "Capture" Mechanism: Why Turkey is Implementing This
For MNEs, the logic is straightforward: If your effective tax rate in a subsidiary country is below 15%, the difference will be collected. The only question is who collects it.
If Turkey had not implemented this Local Minimum Tax, the tax revenue (the difference between your effective rate and 15%) would have been collected by the country where your headquarters is located. Turkey’s stance is pragmatic: "If there is a tax to be paid to reach the 15% global minimum, it should be paid to the Turkish Treasury, not transferred abroad".
The Key Takeaway: You will likely pay the top-up tax regardless. The new regulation ensures that Turkey captures this revenue rather than ceding tax rights to other jurisdictions.
2. Impact on Investment Incentives
Many foreign subsidiaries, such as large automotive manufacturers or industrial plants, operate in Turkey partly due to generous investment incentive certificates. These incentives can sometimes drive the effective tax rate down to as low as 2%.
Under the new system:
Previous Scenario: You paid 2% in Turkey and enjoyed the tax savings.
New Scenario: You will pay the 2% normal corporate tax, plus a 13% top-up tax to Turkey to reach the 15% global standard.
The Turkish administration’s message to foreign investors is clear: Come to Turkey for its geostrategic location and investment climate, not solely for ultra-low tax competition.
3. The Compliance Challenge: VUK vs. IFRS
Perhaps the most significant operational challenge for foreign subsidiaries will be the calculation method. Turkish tax laws (VUK) are strictly rule-based, whereas the Global Minimum Tax relies on International Financial Reporting Standards (IFRS/UFRS), which are principle-based,.
The Conflict: Standard Turkish tax reporting follows specific depreciation rates and doubtful receivable rules set by local law. However, the new tax base will be determined using IFRS financial statements, which rely on economic reality and auditor judgment.
The Risk: This requires a shift in mindset. Tax inspectors and company finance teams will need to bridge the gap between local tax code compliance and international accounting standards.
4. The Silver Lining: Substance-Based Carve-Outs
The system is not entirely rigid. To support the "real economy," the regulation allows for Substance-based Income Exclusions.
A percentage of your eligible payroll costs and the net book value of tangible assets can be deducted from the tax base.
These rates start higher (around 9.8% for assets and payroll) and will gradually decrease to a fixed 5% over time.
This ensures that companies with significant physical presence and employment in Turkey receive a reduction in the top-up tax liability compared to purely digital or holding structures.
Conclusion
For foreign subsidiaries in Turkey, the Local Minimum Complementary Corporate Tax represents a transition from tax competition to tax harmonization. While the overall tax burden may increase for those heavily utilizing incentives, the compliance burden—specifically the reliance on IFRS for tax purposes—requires immediate attention from your finance and tax departments.
