Understanding Income Tax in Turkey: A 2026 Guide for Foreigners
Turkey taxes residents (full taxpayers) on their worldwide income and non-residents (limited taxpayers) only on income from Turkish sources, at progressive rates running from 15% to 40%. Whether that bites depends on one question: are you a Turkish tax resident? This guide explains how residency is decided, the seven income categories Turkey taxes, the live 2026 brackets, the rules that matter most to foreign property owners, and how double-tax treaties stop the same income being taxed twice.
The legal framework for income tax in Turkey
Personal income tax in Turkey rests on three statutes. The substance of who pays and on what is set by the Income Tax Law No. 193 (Gelir Vergisi Kanunu, GVK), in force since 1 January 1961. The machinery — registration, declarations, assessment, penalties and time limits — is governed separately by the Tax Procedure Law No. 213 (Vergi Usul Kanunu, VUK). The earnings of companies are not taxed under the GVK at all; they fall under the Corporate Tax Law No. 5520.
So income tax is a tax on individuals. For a foreigner the practical starting point is always the same two-part question: are you a Turkish tax resident, and which of your earnings does Turkey have the right to tax? Get that wrong and you either overpay or expose yourself to penalties — get it right and the rest is arithmetic.
Tax residency: full taxpayer vs. limited taxpayer
This single distinction controls everything that follows. Turkey splits taxpayers into full taxpayers (tam mükellef), taxed on worldwide income, and limited taxpayers (dar mükellef), taxed only on Turkey-source income.
Full taxpayers (tam mükellef)
The full-liability principle is set in GVK Article 3. You are "settled in Turkey" — and therefore a full taxpayer — if either test in GVK Article 4 is met:
- You have your domicile (ikametgah) in Turkey, meaning a settled home as defined in the Turkish Civil Code No. 4721; or
- You reside in Turkey for more than six months in a single calendar year. Temporary absences do not reset the count.
GVK Article 5 then carves out exceptions: foreigners who come to Turkey for a defined, temporary purpose — a fixed assignment, business, study, medical treatment or a holiday — may not become full taxpayers even after six months.
Limited taxpayers (dar mükellef)
If you do not meet either Article 4 test, you are a limited taxpayer under GVK Article 6, and Turkey taxes only your Turkey-source income. What counts as Turkey-source is itself defined — by GVK Article 7 — and covers, for example, rent from a Turkish apartment, profit from a business carried on in Turkey, or wages for work physically performed in Turkey.
Turkey's domestic six-month rule is not the same as the 183-day test used as a tie-breaker in double-taxation treaties. They can point in different directions, which is exactly why treaty analysis matters whenever two countries both claim you. If your residency status is tied to a permit, our note on residence permits and your tax residency status explains how the two interact.
The seven categories of taxable income
GVK Article 2 lists income exhaustively. If an earning does not fall into one of these seven categories, it is generally outside the scope of income tax altogether:
- Commercial income (ticari kazanç) — profit from a trade or business.
- Agricultural income (zirai kazanç) — farming, livestock and similar activity.
- Salaries and wages (ücret) — employment income, usually taxed at source through withholding.
- Self-employment income (serbest meslek kazancı) — independent professional services and freelance work.
- Income from immovable property (gayrimenkul sermaye iradı, GMSİ) — rental income from real estate and rights; a very common item for foreign owners.
- Income from movable capital (menkul sermaye iradı) — dividends, interest and similar investment returns.
- Other earnings and income (diğer kazanç ve iratlar) — including capital gains, such as the gain on selling property within five years (see below).
Each category carries its own rules on deductible expenses, exemptions and how the income is declared, so two people earning the same amount can owe very different tax depending on where the money came from. If your income is commercial, structuring it through a company can change the picture entirely — see setting up a company in Turkey.
Income tax rates and brackets in 2026
Turkish income tax is progressive under GVK Article 103: the marginal rate climbs through five bands from 15% to 40%, and only the slice of income inside each band is taxed at that band's rate. The lira thresholds are reset every year for inflation. Crucially, Turkey runs two parallel tariffs: wage (employment) income gets wider upper bands than non-wage income, so a salary reaches the higher rates more slowly than rent, business or investment income does.
2026 brackets (Communiqué No. 332)
| Rate | Wage / employment income (TRY) | Non-wage income (TRY) |
|---|---|---|
| 15% | 0 – 190,000 | 0 – 190,000 |
| 20% | 190,001 – 400,000 | 190,001 – 400,000 |
| 27% | 400,001 – 1,500,000 | 400,001 – 1,000,000 |
| 35% | 1,500,001 – 5,300,000 | 1,000,001 – 5,300,000 |
| 40% | over 5,300,000 | over 5,300,000 |
The two tariffs share the first two thresholds and the 40% starting point. They diverge in the middle: non-wage income crosses into the 35% band at TRY 1,000,000, while a salary stays in the 27% band until TRY 1,500,000.
A worked example (illustrative only)
Say a limited taxpayer has TRY 500,000 of net taxable rental income in 2026. Applying the non-wage tariff: the first 190,000 is taxed at 15% (28,500), the next 210,000 at 20% (42,000), and the remaining 100,000 at 27% (27,000) — roughly TRY 97,500, an effective rate of about 19.5%. Your top marginal rate (27%) is always higher than your effective rate, because the lower bands are taxed at lower rates. These numbers are illustrative, not advice: actual liability depends on exemptions, deductions and your residency facts.
Rental income for foreign property owners
Rent from Turkish real estate is income from immovable property (GMSİ) under GVK Article 70, and it is taxable in Turkey even if you are a non-resident, because the property is a Turkish source under Article 7. This is the single most common tax question foreign owners ask, so it deserves its own treatment.
The residential-rent exemption
Income from letting a residential property carries an annual exemption (mesken istisnası). For rental income earned in 2026 the exemption is TRY 58,000. If your residential rent for the year stays at or below that figure and you have no other income obliging you to file, you generally do not declare it; above it, only the excess is taxed. The exemption does not apply to commercial-premises rent, and it is lost if your total income (including salary and investment income) exceeds a separate annual ceiling set each year.
Lump-sum vs. actual expenses
Against your taxable rent you may deduct either:
- a lump-sum deduction (götürü gider) — a fixed percentage of gross rent, with no receipts needed (not available to those who choose the actual-expense method, and not for certain income); or
- actual expenses (gerçek gider) — real, documented costs such as interest, repairs, management and depreciation.
You pick the method that gives the lower tax, but the choice binds you for two years. The rented income is then declared on the annual GMSİ return (see deadlines below).
Selling Turkish property: the 5-year capital-gains rule
Foreign buyers — especially those who acquired property as part of a property investment for citizenship — repeatedly ask whether selling at a profit is taxed. The answer turns on how long you held it.
- Sold within five full years of the date on the title deed (tapu): the gain is a taxable "value-increase gain" (değer artış kazancı) in the "other earnings" category, after deducting an annual exempt amount and indexing the cost for inflation. The taxable balance is then charged at the progressive 15%–40% rates.
- Sold after five years: the gain is generally exempt from income tax for an individual (this exemption does not extend to property held as business stock or by a company).
Filing, declarations, deadlines and your tax number
Turkey runs an annual income tax declaration (yıllık gelir vergisi beyannamesi). The core rules:
- The tax year is the calendar year.
- The annual return is filed by 31 March of the following year — a hard statutory date with no general extension.
- Tax is paid in two equal instalments, by the end of March and the end of July.
- Income already fully taxed at source — such as a single employer's salary — often needs no separate return; rental, business, self-employment and multiple-source income usually does.
Getting a Turkish tax number
A tax number (vergi kimlik numarası) is the first step for any foreigner with Turkish income, and you also need it to buy property, open a bank account or form a company. You can obtain one free of charge:
- in person at any local tax office (vergi dairesi) with your passport; or
- online through the Revenue Administration's interactive portal (interaktif.gib.gov.tr) or via e-Devlet.
Income tax should not be confused with social security (SGK) premiums, which are a separate charge on employment and self-employment — being liable for one does not automatically mean you owe the other.
Avoiding double taxation
If you are a full taxpayer, Turkey taxes your worldwide income, which can collide with tax claimed by your home country. Two mechanisms reduce or remove the overlap:
- Double Taxation Avoidance Agreements (DTAs). Turkey has treaties with more than 85 countries. Each allocates taxing rights between the two states and includes tie-breaker tests — including the 183-day rule, a permanent-home test and a centre-of-vital-interests test — to decide which country treats you as resident.
- Foreign tax credit. The GVK lets tax paid abroad on foreign-source income be credited against the Turkish tax on the same income, within limits.
Claiming treaty relief usually requires a certificate of tax residency from the relevant country. Settle the residency analysis early — before you have filed in either country — to avoid the far harder job of unwinding a double charge after the fact.
How Lexin Legal helps foreign taxpayers
Cross-border tax is rarely a pure numbers exercise — it turns on residency facts, treaty wording and which of the seven categories your income falls into. We help foreigners in Turkey determine their residency status, register with the tax authorities and obtain a tax number, handle rental and property-sale reporting, structure commercial and corporate income (including the interaction with corporate tax and structuring for foreign businesses under the Corporate Tax Law No. 5520), prepare annual declarations and apply treaty relief so the same income is not taxed twice.
If you are unsure how your salary, rent, dividends, capital gain or business profit will be treated, contact Lexin Legal for advice tailored to your facts. You may also find our guide to customs duties when importing into Turkey useful if you trade goods across the border.
Frequently asked questions
When does a foreigner become a Turkish tax resident?
Under GVK Article 4, you are a full taxpayer if you have your domicile in Turkey or reside there for more than six months in a calendar year (Article 3 sets the worldwide-income principle; Article 5 lists temporary-purpose exceptions). Full taxpayers are taxed on worldwide income. If you meet neither test you are a limited taxpayer under Articles 6-7, taxed only on Turkey-source income.
What are the income tax rates in Turkey for 2026?
Income tax is progressive under GVK Article 103, with five bands from 15% to 40%. For 2026 (Communiqué No. 332) the bands are 15% to TRY 190,000, 20% to 400,000, 27% to 1,500,000 (wages) or 1,000,000 (non-wage income), 35% up to 5,300,000, and 40% above. Only the slice within each band is taxed at that rate, so your effective rate is lower than your top rate.
Is rental income from a Turkish property taxable for a foreign owner?
Yes. Rent from Turkish real estate is income from immovable property (GMSİ) under GVK Article 70 and is taxable even for non-residents. Residential rent carries an annual exemption (TRY 58,000 for 2026 income); above it you file an annual return by 31 March, deducting either a lump-sum or your actual documented expenses.
Is selling property in Turkey taxed?
It depends on how long you held it. If an individual sells within five full years of the title-deed date, the gain (after an annual exempt amount and inflation indexing) is taxed at the progressive 15%-40% rates as a value-increase gain. If you sell after five years, the gain is generally exempt from income tax.
How do I get a Turkish tax number?
Free of charge: in person at any local tax office (vergi dairesi) with your passport, or online through the Revenue Administration's interactive portal (interaktif.gib.gov.tr) or e-Devlet. You need a tax number before you can file, buy property, open a bank account or form a company in Turkey.
Will I be taxed twice if my home country also taxes me?
Often not. Turkey has double-taxation treaties with more than 85 countries that allocate taxing rights, and the GVK allows a credit for foreign tax paid on foreign income. A tax residency certificate is generally required to claim treaty relief, so confirm your position before filing in either country.
