Comprehensive 2026 International Tax Guide by GARS Consulting Corporate Law Department
Double Taxation Avoidance Agreements (DTAA / ÇVÖA) play a pivotal role for international investors, foreign business owners, and expatriates operating in Turkey. By 2026, Turkey has active bilateral tax treaties with over 85 countries, preventing cross-border income from being taxed twice and substantially reducing withholding tax (Stopaj) on corporate dividends, royalties, interest, and professional services.
Determining Tax Residency in Turkey
- Individuals (Full Tax Liability): Residing in Turkey continuously or cumulatively for more than 183 days within a calendar year, or establishing a legal permanent domicile.
- Legal Entities: Companies having either their legal registered seat (Kanuni Merkez) or their place of effective management (İş Merkezi) in Turkey.
- Tax Residency Certificate (Mukimlik Belgesi): Official document issued by the Turkish Revenue Administration (GİB) certifying Turkish tax residence.
