      <image:caption>Türkiye&apos;s Law No. 7582, adopted by the Turkish Parliament on 21 May 2026, rewrites the IFC ecosystem on two layers: extending the 100% corporate tax exemption to 2047, and introducing the Qualified Service Centre (QSC) status. Effective 0% corporate tax on foreign-source income, personnel salary exemption up to six times the minimum wage, full transit-trade relief in IFC and Industry Zones. But Pillar Two QDMTT, substance and transfer pricing decide who actually keeps the benefit.</image:caption>

      <image:title>Turkey Technopark 2026: 100% Corporate Tax Exemption and Hidden Compliance Costs</image:title>
      <image:caption>Law No. 4691 Provisional Article 2 grants 100% corporate income tax exemption on software, design and R&amp;D earnings in Turkish Technology Development Zones until 31 December 2028. For foreign investors the headline is attractive, but the operational picture is complex: branch requirement (liaison office structurally excluded under Law 4875), 3% venture capital fund obligation triggered at TL 5,000,000 exempt earnings for FY 2026 (Presidential Decree 10803, Official Gazette 31.12.2025), CPA (YMM) full-attestation report mandatory above TL 500,000 single item or TL 1,000,000 aggregate (Tebliğ 49, OG 30.12.2025), and the 40× minimum wage cap on payroll incentives at TL 1,321,200/month/employee for 2026 (Law 7555, OG 24.07.2025). Compared with Ireland Knowledge Development Box (10% effective, Section 40 Finance Act 2022, commencement order signed 5 Sept 2023, operative 1 Oct 2023) and UK Merged RDEC (20% headline, 15% net), Turkey wins for groups under €750M consolidated revenue; above that, OECD Pillar Two QDMTT (Law 7524) tops the rate up to 15% because the Turkish exemption is not a qualifying refundable tax credit.</image:caption>
