Turkey published Presidential Decision No. 4625 in the Official Gazette on 17 October 2021, which provides for a temporary increase in the time that personnel are allowed to spend outside technology development zones (TDZs) and R&D and design centers, while still qualifying for related tax incentives. As provided in Law No. 7263 of 28 January 2021, the incentives were amended, including that the incentives for personnel engaged in R&D were extended to include time spent outside of TDZs and R&D and design centers, provided that the time spent outside does not exceed 20% of total working hours, which may be increased to 50% by presidential decision. Presidential Decision No. 4625 provides for such an increase to 50%, which applies from 17 October 2021 to 31 December 2022.
