Expat Tax Residency in Turkey

Turkey's personal income tax framework treats resident individuals as full taxpayers subject to worldwide income, while non-residents face Turkish tax only on income sourced within Turkey. The Gelir Idaresi Baskanligi (GIB) -- the Revenue Administration -- administers the framework under the Gelir Vergisi Kanunu (GVK), the Income Tax Law.

Who counts as a Turkish tax resident?

Article 4 GVK establishes two independent paths to Turkish tax residency. The first is legal domicile (ikametgah) in Turkey under the Civil Code -- typically evidenced by a registered address, family presence, and the centre of vital interests being in Turkey. The second is continuous physical presence in Turkey exceeding six months within a single calendar year (1 January through 31 December). Either path alone is sufficient to trigger full tax liability on worldwide income under GVK Article 3. Non-residents are limited taxpayers (dar mukellef) taxed only on Turkish-source income under GVK Article 6 (PwC Worldwide Tax Summaries, Turkey -- Residence).

What exceptions apply to the six-month rule for foreigners?

Not every prolonged stay makes a foreigner a resident. GVK Article 5 carves out several categories that preserve non-resident status even when the six-month threshold is exceeded. Foreign nationals present in Turkey solely to fulfil a specific and temporary business project or assignment are not regarded as residents, regardless of duration. Additional exceptions cover foreign government and consular officials, students, healthcare recipients, and persons held involuntarily due to force majeure such as illness or legal custody. The practical implication is that a company-assigned expatriate on a defined project may remain a limited taxpayer throughout, while a freelancer or long-term digital nomad who crosses six months without a carve-out qualifying assignment will become a full taxpayer. Practitioners document the assignment scope, employer correspondence, and entry-exit records to substantiate any Article 5 position (Istanbul Lawyer Firm, Tax Residency for Foreigners: GVK 4 and DTT Rules).

What are the progressive income tax rates for residents?

Residents self-assess or face withholding on all income types -- employment, business, rental, investment -- at the following bands in effect from 1 January 2026. Thresholds are revalued annually for inflation by GIB; verify the current year's figures at gib.gov.tr before filing.

Thresholds for non-employment income differ at the upper end; the 40 percent rate applies above approximately 1,737,500 TRY for that income category. Half of dividends received from Turkish-resident entities is generally exempt from income tax; the taxable half must be declared when combined income exceeds 400,000 TRY for 2026. Non-residents are taxed on Turkish-source income only, often through withholding at source with no annual return requirement for employment income from a single employer (PwC Worldwide Tax Summaries, Turkey -- Taxes on Personal Income).

What is the new 20-year foreign income exemption under Law 7582?

Law No. 7582, published in the Official Gazette on 4 June 2026, introduces Article 20/D into the GVK. Individuals who become Turkish tax residents from 1 January 2026 onwards and who had no domicile in Turkey and no Turkish tax liability in any of the three preceding calendar years (2023, 2024, 2025) are exempt from income tax on income and earnings derived outside Turkey for 20 years from the date residency commences. Prior passive Turkish income -- rental receipts, securities income, or capital gains from Turkish assets -- alone does not disqualify an applicant. No annual return needs to be filed for income covered by the exemption. Related expenses are non-deductible and foreign taxes paid on exempt income cannot be credited against other Turkish liability. The Ministry of Treasury and Finance sets compliance documentation requirements. This exemption represents a major structural change; individuals considering relocation to Turkey should obtain current implementing regulations from GIB or a credentialed Turkish tax practitioner before relying on it (Mondaq, Law No. 7582 -- Income Tax Amendments, June 2026).

How do double tax treaties interact with Turkish residency?

Turkey has concluded double taxation agreements (DTTs) with over 94 countries, covering most OECD members, major emerging markets, and regional partners. Once an individual is a Turkish tax resident, the worldwide income framework applies, but treaty provisions may reduce or eliminate the Turkish tax due on specific income types sourced in a treaty partner jurisdiction. Treaty tie-breaker articles determine residency where a person qualifies under both countries' domestic rules -- typically resolved by reference to permanent home, centre of vital interests, habitual abode, and nationality, in that order. Non-resident employees from treaty countries may be exempt from Turkish tax on employment income where the employer is not a Turkish resident entity and the employee is not present in Turkey for more than 183 days in a twelve-month period (the standard Article 15 OECD threshold). Consult the relevant bilateral treaty text and any applicable Multilateral Instrument (MLI) modifications; Turkey signed the MLI in 2017.

A qualified Turkish tax professional registered with the relevant bar or professional chamber should be consulted before establishing or departing Turkish tax residency.
