Turkey Personal Income Tax Guide 2026

Overview — Turkish Revenue Administration (Gelir İdaresi Başkanlığı)

The Turkish Revenue Administration (Gelir İdaresi Başkanlığı, GİB) under the Ministry of Treasury and Finance administers all taxes. Every taxpayer is assigned a Tax Identification Number (Vergi Kimlik Numarası). Turkey taxes its residents on worldwide income; non-residents are taxed only on Turkish-source income. The tax year runs from 1 January to 31 December. Annual tax returns (Yıllık Gelir Vergisi Beyannamesi) for the prior year must be filed by the end of March (31 March) and tax due is paid in two equal instalments (March and July).

Personal Income Tax Brackets (2026 Estimated)

Turkey's progressive IIT rates apply to taxable income (vergiye tabi gelir) after deductions. The following brackets are estimated for 2026 based on annual revaluation rates (yeniden değerleme oranı):

• Up to TRY 300,000: 15%
• TRY 300,001–TRY 700,000: 20% (minus TRY 15,000)
• TRY 700,001–TRY 1,700,000: 27% (minus TRY 64,000)
• TRY 1,700,001–TRY 3,000,000: 35% (minus TRY 200,000)
• Above TRY 3,000,000: 40% (minus TRY 350,000)

These brackets are indexed annually for inflation. The rates apply to employment income, business income, professional income, and other ordinary income categories. A separate flat 40% rate applies to certain income types such as copyright and patent income when the taxpayer elects lump-sum determination.

Standard Deduction and Allowances

Minimum Living Allowance (AGI): Abolished effective 2021. Previously, employees received a tax credit calculated as a percentage of the gross minimum wage. As of 2021, the minimum wage was increased significantly and the AGI was removed. Low-income earners effectively benefit from the tax-free minimum wage allowance (minimum geçim indirimi no longer applies; instead the minimum wage itself is exempt from income tax and social security premiums up to a certain base).

Special Education and Health Deductions: Taxpayers may deduct education and health expenses incurred for themselves, their spouses, and dependent children, up to 10% of their declared gross income. Qualifying expenses must be supported by invoices and receipts. These are deductible from the gross income before arriving at taxable income, provided they are documented and related to the taxpayer's or dependents' welfare.

Life Insurance Premiums: Deductible up to the higher of TRY 2,000 or 5% of annual gross income (for the taxpayer, spouse, and children).

Charitable Donations: Deductible up to 5% of gross income for donations to certain public benefit organisations; 100% deductible for donations to state schools, health facilities, and certain cultural institutions.

Employment Income — Pay-as-You-Earn (Stopaj)

Most employees have income tax withheld at source by their employer through the stopaj (withholding) system. The employer calculates the tax using the progressive IIT brackets and remits it to the tax office monthly. The employer must also withhold social security premiums (SGK) on behalf of the employee. Employees with a single employer and only employment income do not need to file an annual return — the withholding is considered final tax. Employees wishing to claim deductions (education, health, donations) may file a return to claim refunds.

Self-Employment and Business Income

Self-employed individuals (şahıs şirketi or freelance professionals) must file an annual income tax return. Business income is determined as gross revenue minus deductible business expenses. Turkey uses two methods: the balance sheet method (bilanço esası) for larger businesses and the simple method (işletme hesabı esası) for smaller enterprises. Freelance professionals (e.g., doctors, lawyers, consultants) are subject to withholding at source (20%) on their gross fees, which is credited against their final annual tax liability.

Filing and Payment

Annual return deadline: 31 March of the following year (e.g., 2025 income return due by 31 March 2026).

Tax payments: Tax is paid in two equal instalments — the first by 31 March and the second by 31 July.

Electronic filing: All tax returns must be filed electronically via the GİB's online portal (Hazır Beyan Sistemi for simplified returns or the main e-Declaration system).

Penalties: Late filing and late payment penalties apply, including tax loss penalties (vergi ziyaı cezası) of up to 100% of the underpaid tax plus monthly late payment interest.

FAQs

Is the minimum wage really tax-free?

As of 2021, the portion of income up to the minimum wage is exempt from both income tax and stamp tax for employees. This means employees earning minimum wage effectively pay zero income tax. The exemption applies only to employment income, not to business or rental income.

Can foreign residents claim deductions?

Yes, foreign residents are subject to Turkish IIT on their Turkish-source income only and can claim deductions proportionally related to that income. However, personal allowances (education, health) apply only to the extent the expenses are incurred in Turkey.

Do I need to file a return if I have only one employer?

No, if all your income is from a single employer and it has been subject to withholding (stopaj), no annual return is required. You may voluntarily file to claim deductible expenses that were not accounted for in withholding.

What if I have rental income in addition to salary?

Rental income (apart from exempt amounts) must be declared in an annual return. The salary income will also be included, and the progressive brackets apply to the combined income. The tax already withheld from salary is credited against the total tax due.
