Turkey Income Tax Guide for Expatriates (2025–2026)

Residency: In Turkey, individuals are tax residents if they have legal domicile in Turkey or reside over 6 months (183 days) in a calendar year. Residents are taxed on worldwide income; non-residents are taxed only on Turkish-source income. (Exception: short-term project assignments or force-majeure stays over 6 months do not create residency.) A resident is a “full taxpayer” (global income), while a non-resident is a “limited taxpayer.”

• Domicile or 6-month rule: Turkish nationals and foreigners with domiciles in Turkey, or foreigners staying >6 months/year, are residents.

• Special cases: Temporary project assignments (>6 mos) remain non-resident status, and forced stay (illness, arrest) does not trigger residency.

Tax Rates & Brackets: Turkey has progressive personal income tax rates (2025): 15%, 20%, 27%, 35%, 40%. For 2025, the brackets (annual taxable income) are:

• 0–TL158,000: 15%

• TL158,001–330,000: 20% (on income above TL158k)

• TL330,001–800,000: 27% (on income above TL330k)

• TL800,001–4,300,000: 35% (above TL800k)

• Over TL4,300,000: 40%

(These rates apply to general income; wage income brackets are slightly wider—e.g. 27% bracket extends to TL1,200,000—reflecting payroll “full-month” thresholds.) Income taxed at these rates includes salary and other earnings. There are no special expat rates; non-residents pay the same rates on their Turkish-source income.

Taxable Income: Both residents and non-residents are taxed on all Turkish-source income. Major categories include:

• Employment income (wages, salaries, benefits): All cash and non-cash compensation (bonus, housing allowance, etc.) is taxable. Resident’s foreign salaries are taxable; non-resident is taxed on Turkey-work or Turkey-paid wages (unless a DTT exemption applies). Employers withhold monthly tax under PAYE.

• Self-employment / business income: Net profits from Turkish activities are taxed for anyone (resident or not); a resident’s foreign business income is also taxed. Expats doing professional work in Turkey must keep accounting and file returns.

• Rental income: Income from Turkish real estate (houses, apartments, commercial) is taxable. However, rental income from a personal residence is exempt up to TL47,000 (2025). (If over, the excess must be declared.) Rental income from business property has thresholds based on combined income, but generally all rent is taxable after expenses.

• Investment income:

  • Dividends: Residents get 50% exemption on domestic dividends. (If the remaining taxable portion plus other income exceeds TL330,000, the full amount must be reported.) Foreign dividends >TL18,000 are taxable, with 50% exemption if the taxpayer owns ≥50% of the payer and remits by filing date. A 15% withholding applies to dividends (creditable).

  • Interest: Bank interest and bond income have statutory withholding rates (often final). Turkish government/corporate bond interest (issued after 2006) is 10% WHT. Bank deposit interest: 5–15% depending on currency and term (for residents; non-residents pay 10–25%). Foreign interest (above TL18k in total with other movable/immovable income) must be declared.

  • Capital gains: Gains on Turkish securities and government bonds are generally subject to withholding tax (often 0% or 10%) under Article 67. Gains not subject to final WHT (e.g. on certain bonds bought before 2006 or other assets) are taxed at regular rates via self-assessment. Capital gains on real estate: no general annual exemption for sales (except for long-term exemptions for principal residence after 5 years), so short-term property gains are taxable.

Filing & Deadlines: Tax year is calendar year. Returns for 2025 income are due by 31 March 2026. No extensions are allowed. In practice, the annual return season (beyannames) is typically 1–31 March of the following year.

• Who must file: Most wage earners have tax withheld and do not file returns, unless they meet certain conditions (e.g. second employer income >TL330k, total income tax base >TL4.3M, foreign salary with no Turkish withholding, etc.). All self-employed or business income earners must file. Expats leaving Turkey must settle any remaining tax and file before departure.

• Procedure: Taxpayers register with the Revenue Administration to get a Tax Identification Number (Vergi Kimlik No.). Returns are filed electronically via the Tax Authority’s portal (e-Beyanname), although paper filing at a local tax office is still possible. Payment is usually online or at banks. Any remaining tax due after withholding is paid in two installments (end-March and end-July). Quarterly advance (“temporary”) tax payments (15% of quarterly profit) are required for business income.

Documentation & Language: All filings and official documents must be in Turkish. Taxpayers should keep detailed records of income (pay slips, invoices, dividend statements, rent contracts, etc.) and deductible expenses (receipts for donations, education, insurance premiums, etc.). Foreign-source documents (pay stubs, interest statements from abroad) should be translated by a sworn translator. Commonly required documentation: Turkish ID or passport, signed tax returns, proof of income and taxes paid (e.g. employer withholding statements), receipts for deductions, and any tax treaty certificates. (All correspondence and returns with the Turkish tax office must be in Turkish.)

Withholding Obligations: Turkey relies heavily on withholding at source:

• Employment income: Employers withhold income tax each payroll (PAYE). Expats’ salaries paid through a Turkish payroll are taxed at source.

• Investment payments: Dividends (15% WHT on gross) and interest from Turkish bonds/bank accounts are generally withheld by the payer (often final for non-residents). Royalties, technical service fees and rent payments to individuals are subject to 20% withholding (non-residents) or 15–20% for residents (creditable). For example, lease of Turkish property by a company to a resident individual carries 20% WHT.

• Procedural note: WHT on salaries and investment income counts as a tax payment. Non-residents’ final tax obligation is usually satisfied by these withholdings (they need not file a return if only Turkish-source income was withheld). Residents may credit withholding against their final tax due.

Tax Credits & Deductions: Turkey has no personal allowance (everyone uses progressive brackets on net income). Instead, certain deductions and credits are allowed up to specified limits:

• Charitable donations: Gifts to approved charities and public institutions are deductible up to statutory limits.

• Education & health expenses: Taxpayers can deduct documented education or medical expenses for themselves or family members, up to 10% of the annual tax base. (Requires receipts and proper invoicing.)

• Insurance premiums: Life, disability and private health insurance premiums (for taxpayer, spouse, children) are deductible up to 15% of total taxable income or the annual minimum wage amount, whichever is higher.

• Employee social security: Mandatory employee Social Security (Sosyal Güvenlik) contributions are automatically deducted from payroll and reduce taxable salary (i.e. already taken into account in withheld tax).

• Home office / expenses: No general home office deduction unless incorporated as a business expense.

• Stopaj indirim (former payroll rebate): Note that recent law changes have effectively eliminated the former annual tax rebate for employees; instead, withheld tax is final upon filing if no deductions apply.

• Foreign tax credit: Residents can credit foreign income taxes paid (with proof) against Turkish tax on that income, up to the Turkish tax amount. This prevents double-taxation. Turkey has DTTs with many countries (US, UK, EU, etc.); treaty provisions (reduced WHT rates, exemptions) and foreign tax credits generally mitigate double-taxation.

• Tax treaties: Many treaties allow relief (e.g. exempting some foreign employment income, reducing WHT on dividends/interest, etc.). (See Foreign Income below.)

Foreign Income & Treaties: A Turkish tax resident is taxed on worldwide income. Any foreign income (salary, dividends, etc.) must be declared, with credit given for any taxes paid abroad. Under most tax treaties, foreign employment (if covered by home country social security) may be exempt or taxed only in the home country, etc. Residents should report foreign dividends/interest if they exceed reporting thresholds (TL18,000 for portfolio income in 2025). Non-residents pay tax only on Turkish-source income. Turkey has tax treaties with ~100+ countries; for instance, treaties often cap WHT on dividends/interest at lower rates and permit credits. Turkey also has bilateral social security agreements (EU, US, etc.) to avoid double contributions.

Penalties & Enforcement: Turkey enforces compliance with strict penalties:

• Late filing penalty: If the annual return is filed late, a fixed late-filing fine is imposed (for individuals, typically a few hundred TL per month of delay, up to a limit). (Exact amounts vary by year.)

• Late payment interest: Unpaid tax incurs a monthly default interest (gecikme zammı). As of Nov 2023, this rate is 3.5% per month of the overdue tax (up from 2.5%). It accrues daily on the unpaid balance.

• Underpayment penalties: Deliberate underreporting or evasion can trigger a “tax loss” penalty equal to 50–100% of the unpaid tax (higher for fraud). Failing to report foreign income or falsely claiming deductions may incur up to 100% penalty.

• Installment default: If installment payments are missed, interest and surcharges apply. The official “tecil faizi” (installment interest) is now ~36% annually on deferred tax.

• Other fines: Failure to register, missing WHT declarations, or non-compliance (e.g. payroll reporting) leads to statutory administrative fines (often several hundred TL per missing item).

• Enforcement: The tax authority can audit, freeze bank accounts, seize assets or block notary services for unpaid tax. Given Turkey’s increasing use of information exchange and digital records, aggressive enforcement and audits have become common. Penalties can be mitigated only by prompt voluntary disclosure (there is a small “voluntary disclosure” reprieve at 3.5% interest).

Key 2025–2026 Updates: The tax regime is largely stable, but thresholds and rates are updated annually:

• Bracket and allowance inflation indexation: 2025 brackets/deductions were increased by the revaluation rate (~43%). (For example, the top 40% bracket now starts at TL4.3M). All official thresholds (e.g. minimum taxable income, depreciation limits) rose similarly per the 329-series Income Tax Communiqué.

• Rental exemption: The exempt amount for residential rent rose to TL47,000 (2025) (up from TL44,000 in 2024). Over this, rental income must be declared.

• Other allowances: Tax-free fringe benefit caps were updated: e.g. meal allowances outside workplace increased to TL240/day (2025), and transport benefits to TL126/day. These affect employer withholding but are relevant to taxpayers with these benefits.

• Late interest: As above, late-payment interest is now 3.5% monthly (Nov 2023 change).

• No new expat regime: There is no new special tax break for foreigners. Previous temporary exemptions (e.g. for short-term foreign employment) remain unchanged. The government has signaled tighter enforcement (e.g. audits of returns).

• Legislation in progress: A 2025 draft law proposes limiting some PI tax exemptions (e.g. for R&D personnel), but this is still pending. Other recent measures (e.g. higher stamp-duty on filings, updates to vehicle expense rules) are largely administrative.
