Who Qualifies for the 20-Year Exemption?

The two-part eligibility gate

Eligibility for Türkiye's 20-year foreign income exemption turns on two questions. Do you become a Turkish tax resident from 1 January 2026 onward? And in the three calendar years before that, did you keep clear of Türkiye — with no domicile and no Turkish tax liability? Answer yes to both and, subject to the detail below, you are in scope of Mükerrer Madde 20/D.

Why "three calendar years" is not "36 months"

This distinction catches people out. The lookback is measured in full calendar years, not a rolling 36-month period counted back from the day you arrive. So the relevant window is the three complete tax years preceding the year you become resident — assessed year by year. And the test is unforgiving in one respect: a single disqualifying year defeats the whole claim. You cannot offset a bad year against two clean ones.

Past ties that do not disqualify you

Crucially, not every prior connection to Türkiye is fatal. The law protects tax liability that arose only from passive Turkish assets. If, during the lookback, your sole Turkish tax exposure came from:

• income from immovable property — e.g. rent on a Turkish home you own;
• income from movable capital — Turkish interest or dividend income; or
• capital gains on Turkish assets,

then your eligibility survives. Owning and letting a Turkish apartment, or holding a Turkish investment account, is compatible with the exemption.

What burns your eligibility

The disqualifiers are active connections to Türkiye. Turkish employment income in any of the three years is the most common one — a Turkish salary in the lookback denies the certificate. So does commercial, professional or business tax liability, and, of course, having been a full Turkish tax resident already. The theme is clear: the regime rewards genuine new arrivals and genuine returnees, not people who never really left.

Nationality is irrelevant

One of the most important features is what the test does not ask: your passport. The exemption is not limited by nationality. It reaches incoming foreigners and returning Turkish professionals on identical terms — what matters is prior non-residence, not where you were born.
