What Do the Amendments Introduced by the Decree Mean?
A. Amendments Regarding the Foreign Participation Income Exemption
I. From the Perspective of Individual Shareholders
Pursuant to Article 22 of the Income Tax Law, dividend income derived from foreign participations meeting certain conditions has been subject to a 50% income tax exemption, provided that such income is transferred to Türkiye by the deadline for filing the relevant annual income tax return. In order to benefit from this exemption, it was required that the individual hold a minimum participation interest of 50% in the foreign entity.
With Article 1 of the Decree, the minimum participation threshold required to benefit from the foreign participation income exemption has been reduced from 50% to 20%.
II. From the Perspective of Corporate Taxpayers
Similarly, the minimum participation threshold stipulated under Article 5/1-b of the Corporate Tax Law for the foreign participation income exemption has also been reduced from 50% to 20%. In addition, the portion of participation income that may be taken into account within the scope of the exemption has been increased from 50% to 80%.
Provided that these conditions are met, the obligation to transfer the participation income to Türkiye by the deadline for filing the corporate tax return for the relevant fiscal year continues to apply.
The said amendments entered into force on 30 April 2026, the date of their publication, and shall apply to income and earnings derived in taxation periods beginning on or after 1 January 2026.

Accordingly, the deduction rate applied at 80% under Article 89/1-13 of the Income Tax Law and Article 10/1-ğ of the Corporate Tax Law has been increased to 100% pursuant to the Decree.
