The landmark tax incentive introduced under Mükerrer Article 20/D of the Turkish Income Tax Law (GVK) (via Law No. 7582) offers an unprecedented 20-year income tax exemption on foreign-sourced earnings for individuals relocating to Turkey.

To qualify for this extensive "tax holiday," an individual must meet several strict, cumulative conditions outlined in the law and the subsequent General Communiqué No. 333, which finalized the rules on July 4, 2026

1. Establishment of Tax Residency in Turkey (Tam Mükellefiyet)

The individual must qualify as a tax resident (unlimited tax liability) in Turkey under GVK Article 4. This requires meeting at least one of the following criteria:

• Establishing a legal domicile (residence) in Turkey.
• Staying in Turkey continuously for more than six months within a single calendar year (temporary absences do not interrupt this residency period). The exemption applies strictly to individuals who are deemed to have established tax residency in Turkey on or after January 1, 2026.

2. The Three-Year Non-Residency Rule

Prior to the date they establish residency in Turkey, the individual must not have had a legal residence or been considered a tax resident in Turkey during the preceding three calendar years. This rule ensures that the system is not utilized as a short-term loop by individuals who recently exited the Turkish tax system.

3. The Three-Year Non-Taxpayer Rule (With Vital Exceptions)

The applicant must not have had any active income tax liability in Turkey during the preceding three calendar years. However, to accommodate global investors, the law provides a major exception. Having prior tax liability or filing returns in Turkey during those three years solely for the following categories does not disqualify the applicant:

• Rental income from immovable property (gayrimenkul sermaye iradı).
• Capital income such as interest, dividends, or securities (menkul sermaye iradı).
• Capital gains from the sale of assets (değer artışı kazancı).

4. Real Person Status

This exemption is strictly reserved for natural persons (individuals). It is open to both Turkish citizens (such as returning expats/gurbetçiler) and foreign nationals who move to Turkey. Corporations, businesses, or corporate tax entities cannot claim this exemption, even if they relocate their operations or business headquarters to Turkey.

5. Mandatory & Timely Application for the "Exemption Certificate"

The 20-year exemption does not apply automatically; you must proactively obtain an "Exemption Certificate for Earnings and Revenues Obtained from Abroad" (Yurt Dışından Elde Edilen Kazanç ve İratlar İçin İstisna Belgesi) from your authorized local tax office.

• The Deadline: As a general rule, the application must be submitted by the end of the calendar year in which you are first deemed to have established residency.
• The Winter Extension: If you are deemed to have established residency in the final two months of the year (November or December), you have until the end of February of the following calendar year to submit your application

Important Operational Rules of the Exemption

• Scope of Income: The exemption covers all seven elements of income under Turkish tax law, provided they are earned outside of Turkey. This includes foreign salaries, foreign dividends/interest, rental income from foreign real estate, foreign capital gains, foreign pensions, and foreign royalties.
• No Annual Declarations: Qualifying foreign-sourced income does not need to be declared on an annual tax return, nor is it included in returns filed for taxable local incomes.
• Non-deductibility of Related Costs: Any expenses, costs, or losses incurred in connection with the exempt foreign income cannot be deducted from your taxable Turkish-source income.
• No Foreign Tax Credits: Taxes paid in foreign countries on these exempt earnings cannot be offset or credited against any income tax liabilities generated within Turkey.
• Subsequent Loss of Status: If it is later discovered that an individual did not meet the conditions (e.g., they had an undisclosed commercial registration in the prior three years), the exemption is canceled, and unpaid taxes are recovered with tax loss penalties and interest

Summary of Compliance and Strategic Implementation

The "İstisna Belgesi" is the taxpayer's primary legal shield. Without this government-stamped document—the template for which (EK-1) is found in Seri No. 333—an individual is treated as a standard taxpayer, liable for Turkish tax on their worldwide income.

Strategic Checklist for New Residents:

1. Verification: Confirm non-taxpayer status (excluding passive income) for the three full calendar years preceding the move.
2. Residency: Formally establish residency after January 1, 2026, and document the date of entry and domicile.
3. Application: Submit the application for the Exemption Certificate to the tax office within the statutory window (end of year or February extension).
4. Segregation and Documentation: Maintain Contemporaneous Documentation, including foreign bank statements and dividend vouchers, to clearly segregate exempt foreign income from any Turkish-source activities.

General Communiqué Seri No. 333 provides the definitive roadmap for these procedures and remains the final authority for compliance. When executed with precision, GVK Mükerrer Madde 20/D offers one of the most competitive wealth management environments in the world.
