Turkey sits at the crossroads of Europe and Asia and has become an increasingly popular base for expats, remote workers, and retirees — particularly those attracted by its lower cost of living and strategic time zone. But Turkey's tax system has some distinctive features that expats must understand: the 6-month residency trigger, annually adjusted brackets due to high inflation, and significant social security obligations.
This guide covers Turkey's income tax structure for 2026, when tax residency triggers, how social security works, what the currency environment means for USD- or EUR-paid expats, and what US citizens in Turkey must file with the IRS.
According to the Gelir İdaresi Başkanlığı (Turkish Revenue Administration), Turkey's income tax uses five progressive brackets. The rates themselves are stable, but the income thresholds are adjusted annually for inflation — Turkey has experienced very high inflation in recent years, so the TRY amounts change significantly each year:
| Taxable Income (TRY) | Rate |
|---|---|
| Up to ~110,000 | 15% |
| ~110,001–~230,000 | 20% |
| ~230,001–~580,000 | 27% |
| ~580,001–~3,000,000 | 35% |
| Above ~3,000,000 | 40% |
Important: These thresholds are approximate 2026 figures. Turkey adjusts brackets annually to account for inflation — always verify current thresholds directly at gib.gov.tr before filing.
For USD or EUR-paid expats, the TRY equivalent of your income changes with the exchange rate. At 2026 exchange rates (approximately 35–38 TRY per USD), an expat earning $60,000 USD falls comfortably into the 35% bracket on their TRY-equivalent income.
Turkey's tax residency rules differ from many European countries in a key way: the threshold is 6 months (183 days) in Turkey within a calendar year. This is the primary trigger for worldwide income taxation.
Expats spending fewer than 6 months in Turkey in a calendar year are treated as non-residents and taxed only on Turkish-source income. This makes Turkey relatively accessible for part-year residents and digital nomads who stay under the threshold.
Foreigners who come to Turkey specifically for business, scientific research, education, or health treatment, and who do not intend to settle in Turkey, may not be considered tax residents even after 6 months — but this is fact-specific and requires confirmation with a Turkish tax adviser.
Turkey's social security system is administered by the Sosyal Güvenlik Kurumu (SGK). Employees and employers both contribute based on gross salary:
| Component | Employee Rate | Employer Rate |
|---|---|---|
| Long-term insurance (pension/disability) | 9% | 11% |
| Short-term insurance (work accidents) | 0% | ~1.5% (sector-based) |
| General health insurance | 5% | 7.5% |
| Unemployment insurance | 1% | 2% |
Total employee SGK: approximately 14% of gross salary. Total employer SGK: approximately 22–23% of gross salary.
Foreign employees working in Turkey under an employment contract with a Turkish employer are generally required to enrol in SGK. Turkey has social security totalization agreements with several countries — if your home country has an agreement, you may be exempt from Turkish SGK contributions while continuing to contribute to your home country system. Check whether a totalization agreement exists between Turkey and your country of origin.
Turkey's high inflation and currency depreciation create unique tax planning considerations for expats paid in foreign currency:
Income received in USD, EUR, or other foreign currencies is converted to Turkish Lira (TRY) at the exchange rate on the date of receipt for tax purposes. As the TRY has depreciated significantly, this means USD-paid expats' tax liability (in TRY) rises every year simply due to currency movements — even if your USD income is flat.
An expat earning $60,000 USD per year in 2023 would have had a different TRY-equivalent tax bracket than the same person in 2026. Always calculate your expected Turkish tax liability in TRY using the current exchange rate, not a historical one.
Converting TRY salaries to USD, EUR, or GBP is subject to Turkish banking regulations. Large transfers require documentation of the tax source of funds. Using an international transfer service ensures compliance and significantly reduces conversion costs versus Turkish retail bank rates.
Turkish tax returns (yıllık gelir vergisi beyannamesi) are filed annually with the local Vergi Dairesi (tax office). Key dates:
Employees whose only income is salary subject to withholding (stopaj) at source may not need to file a separate return — the employer's withholding settles their liability. However, expats with:
...must file a full annual return.
Online filing is available via the Turkish Revenue Administration's portal (GİB Portal). A Turkish tax number (vergi kimlik numarası) is required for all taxpayers and can be obtained from any Vergi Dairesi or online.
US citizens living in Turkey must file US federal tax returns annually. Turkey's income tax rates are generally lower than US marginal rates at lower to mid incomes, so the Foreign Tax Credit may not fully offset US liability in all cases.
