Turkish Tax Residency When You Move Abroad (2026)
Key takeaways
- Two statuses. Full liability (tam mükellefiyet) means tax on worldwide income; limited liability (dar mükellefiyet) means tax only on income arising in Türkiye.
- The residence tests. You are resident if you are domiciled in Türkiye (per the Civil Code) or you reside in Türkiye for more than six months in a calendar year; brief trips abroad do not break that period.
- Exceptions exist. Certain people on temporary assignments (experts, business people, journalists, students, those here for treatment or travel) are not treated as resident even beyond six months.
- Leaving flips the switch. When you leave permanently and no longer meet the tests, later worldwide income falls outside Turkish tax; only Türkiye-source income remains taxable.
- Treaties decide ties. Türkiye’s double-taxation agreements contain tie-breaker rules that settle which country taxes you if both claim you in a transition year.
- Keep your tax number. The 10-digit vergi kimlik numarası stays valid and is needed for any remaining Turkish filings, property sales or bank matters.
Full versus limited liability: the core distinction
Turkish personal income tax rests on a single question: are you a full taxpayer or a limited taxpayer? Under Article 3 of the Income Tax Law No. 193 (Gelir Vergisi Kanunu), individuals who are “resident in Türkiye” are subject to tam mükellefiyet — full liability — and are taxed on all income they earn, whether inside or outside Türkiye. This is the worldwide-income basis. By contrast, individuals who are not resident are limited taxpayers (dar mükellef) under Articles 6 and following, and Türkiye taxes only the income they derive from Turkish sources. The full text of the law is published by the Presidency’s legislation portal, mevzuat.gov.tr, and the Revenue Administration (Gelir İdaresi Başkanlığı) explains the framework at gib.gov.tr.
The practical upshot for anyone emigrating is straightforward: while you remain resident, a salary, rental income or business profit earned anywhere in the world can be within the Turkish net; once you cease to be resident, only what arises in Türkiye stays taxable here.
The residence tests under Article 4
Article 4 of Law No. 193 defines who counts as “resident” (yerleşmiş sayılanlar). Two independent tests apply. First, anyone whose legal domicile (ikametgâh) is in Türkiye is resident — domicile carries the meaning set out in the Turkish Civil Code, broadly the place where a person settles with the intention of remaining. Second, anyone who stays in Türkiye for more than six months in a calendar year is resident. The law adds an important clarifier: temporary absences do not interrupt the running of that six-month period, so you cannot reset the clock with short trips abroad. Türkiye’s own residency description filed with the OECD confirms both limbs of the test (OECD — Türkiye residency for tax purposes).
Because the count is measured “in a calendar year”, presence is assessed year by year. Someone who leaves partway through a year may still be resident for that year if they had already crossed six months; the following full year abroad they generally will not be.
Article 5 exceptions: staying long without becoming resident
Article 5 lists people who are not deemed resident even if their stay exceeds six months. These include business people, scientists, experts, officials and press correspondents who come to Türkiye for a specific or temporary assignment, and people who come for study, medical treatment, rest or travel. The logic is that a defined, temporary purpose does not create Turkish residence. This matters mainly in reverse for emigrants — it shows that Turkish law looks at the nature of a stay, not merely the day-count, which supports the position that a genuine, permanent departure ends residence. The provision sits in the same statute at mevzuat.gov.tr.
What “leaving” changes, and what stays taxable
When you emigrate for good and stop satisfying the Article 4 tests — you give up your Turkish domicile and no longer spend more than six months a year in the country — you become a limited taxpayer. From that point Türkiye may tax only Türkiye-source income. The main categories are income from immovable property located in Türkiye (for example rent from a Turkish flat), business profits earned through a permanent establishment in Türkiye, employment income for work physically performed in Türkiye, and Turkish-source dividends, interest and royalties. Much of the passive income of non-residents is collected through withholding at source under Article 94 of the law, which often settles the Turkish tax without a separate return. The Revenue Administration publishes a dedicated English guidebook for non-resident taxpayers on rental income at gib.gov.tr.
Worldwide income you earn after you cease to be resident — a foreign salary, foreign investment returns — is outside the Turkish base. The pivot is your residence status, not your citizenship: Turkish nationals living genuinely abroad can be limited taxpayers, and the law even treats certain citizens posted overseas by Turkish public bodies as a special case.
Double-taxation treaties and the transition year
In the year you move, both Türkiye and your destination may each consider you resident under their domestic rules. Türkiye has an extensive network of double-taxation agreements (çifte vergilendirmeyi önleme anlaşmaları) whose “tie-breaker” article decides a single residence for treaty purposes — typically by permanent home, then centre of vital interests, then habitual abode, then nationality. The Revenue Administration lists the treaties in force at gib.gov.tr. If you keep a Turkish property, pension or bank interest after leaving, the relevant treaty may also cap the Turkish withholding rate, so it is worth reading the article that covers each income type.
Practical steps on departure
There is no general “exit tax” on individuals simply for emigrating, but you should close your Turkish tax affairs cleanly. Notify your tax office (vergi dairesi) of your change of status and address, file any final income tax return covering the part of the year you were resident, and settle outstanding liabilities. Keep your tax number (vergi kimlik numarası) — the 10-digit identifier issued by the Revenue Administration — because you will need it for any remaining Turkish filings, to sell property, or to reclaim over-withheld tax under a treaty. Foreign nationals can obtain or confirm a tax number online through the Digital Tax Office at dijital.gib.gov.tr. If you still owe Turkish tax on rent or other local income after leaving, you may need to file as a limited taxpayer or rely on withholding, as explained in the Revenue Administration guidance.
Is there an exit tax, and what about the year you leave?
Türkiye does not levy a general “exit tax” on individuals for the act of emigrating, and it does not tax unrealised gains simply because you cross the border. What you do face is ordinary settlement: for the calendar year in which you leave, you are typically a full taxpayer for the part of the year you were resident, so income earned worldwide up to your departure can fall within Turkish tax, while income after you cease to be resident is assessed on the limited (Türkiye-source) basis. Annual income tax returns are normally filed in March for the previous year, so a mid-year departure usually means a return the following spring covering your resident period. If tax was withheld at source on Turkish income and a treaty gives a lower rate, you can seek a refund of the excess. The Revenue Administration sets out filing obligations and deadlines at gib.gov.tr, and the statutory basis remains the Income Tax Law No. 193 at mevzuat.gov.tr.

Frequently asked questions
Does moving abroad automatically end my Turkish tax residency?
Not automatically — it ends when you stop meeting the tests in Article 4 of Law No. 193, meaning you give up your Turkish domicile and no longer stay more than six months a year in Türkiye. Read the statute at Source.
What is the difference between tam mükellef and dar mükellef?
A full taxpayer (tam mükellef) is taxed on worldwide income; a limited taxpayer (dar mükellef) is taxed only on Türkiye-source income. The distinction is set out by the Revenue Administration at Source.
Will Türkiye still tax my rent from a Turkish flat after I leave?
Yes. Income from immovable property located in Türkiye is Türkiye-source income and remains taxable for non-residents; the Revenue Administration publishes a non-resident rental-income guidebook at Source.
Does the six-month count reset if I take short trips out of Türkiye?
No. Article 4 states that temporary absences do not interrupt the six-month residence period. See Source.
What if both Türkiye and my new country treat me as resident?
The applicable double-taxation treaty contains tie-breaker rules that assign a single residence for treaty purposes. Türkiye lists its treaties at Source.
Should I keep my Turkish tax number after emigrating?
Yes. The vergi kimlik numarası remains valid and is needed for any Turkish filings, property sales or refunds; foreigners can manage it via the Digital Tax Office at Source.
