Understanding Tax Residency Status in Türkiye

The foundation of any tax strategy begins with determining your residency status. In Türkiye, individuals who reside in the country for more than six months within a calendar year are considered tax residents and are subject to taxation on their worldwide income. Non-residents, conversely, are only taxed on income sourced from Türkiye.

This distinction carries significant implications for your tax obligations, filing requirements, and available deductions. Many expatriates find themselves in complex situations where they maintain ties to multiple countries, creating potential double taxation scenarios or unclear residency positions. Professional guidance from an experienced Istanbul accountant becomes invaluable in these circumstances.

Tax Resident Status

You are generally considered a tax resident in Türkiye if:

• You reside in Türkiye for more than six months in a calendar year, or
• You have a permanent home or center of vital interests in Türkiye.

Tax residents are subject to worldwide income taxation, meaning global income must be declared in Türkiye.

Determining Your Tax Residency in 2026

The first step in any tax planning strategy is determining whether you are a “Full” or “Limited” taxpayer. In 2026, the 183-day rule remains the primary benchmark.

• Full Taxpayers (Residents): If you reside in Türkiye for more than 183 days in a calendar year or have a legal domicile here, you are taxed on your worldwide income.
• Limited Taxpayers (Non-Residents): If you stay for less than six months, you are only liable for income earned from Turkish sources (e.g., rental income from an Istanbul property or a salary paid by a Turkish entity).

Updated Income Tax Brackets for 2026

Türkiye employs a progressive tax system. For the 2026 fiscal year, rates range from 15% to 40%. Accurate tax compliance requires staying ahead of these thresholds, which are adjusted annually for inflation.

Non-Resident Status

Non-residents are taxed only on income sourced in Türkiye, such as:

• Rental income from Turkish real estate
• Employment income earned in Türkiye
• Business income attributable to Turkish activities
• Capital gains from Turkish assets

Correctly determining residency is critical and often requires professional analysis, especially for expats with cross-border income streams.

Scope of Expat & Non-Resident Tax Services

Our expat-focused solutions are structured to address the full lifecycle of your tax obligations in Türkiye, from registration to reporting and strategic planning.

Tax Registration and Initial Setup

Before any declaration can be made, expats and non-residents must complete proper tax registration with the Turkish Revenue Administration. This includes:

• Obtaining a Turkish tax identification number
• Registering rental, employment, or business income
• Aligning registrations with residence permits or work permits

Early errors during registration often lead to long-term compliance issues. Professional handling ensures accuracy from the outset.

Income Tax Compliance for Expats

Employment Income

Foreign nationals working in Türkiye are subject to progressive income tax rates. In certain cases, exemptions or treaty benefits may apply, particularly for short-term assignments or foreign payroll structures.

Self-Employment and Freelance Income

Remote workers and consultants earning income connected to Türkiye must assess:

• Whether a permanent establishment exists
• Whether VAT registration is required
• Withholding obligations and advance tax payments

Our team ensures full tax compliance while preventing overpayment or duplicate taxation.

Rental and Real Estate Taxation

Many non-residents own property in Türkiye as an investment or secondary residence. Rental income is subject to:

• Annual income tax declarations
• Allowable deductions (expenses or lump-sum method)
• Withholding considerations in commercial leases

Capital gains tax may also apply when selling property within specific holding periods. Accurate reporting and strategic planning can significantly reduce exposure.

Double Taxation Treaties and Treaty Relief

Türkiye has an extensive network of double taxation avoidance agreements (DTAs) with many countries. These treaties are essential for expats and non-residents as they:

• Prevent the same income from being taxed twice
• Allocate taxing rights between countries
• Reduce withholding tax rates on certain income types

Treaty application requires correct interpretation, documentation, and disclosure. Improper use may trigger audits or penalties.

Tax Planning for Expats and International Individuals

Effective tax planning goes beyond annual filings. For expats and non-residents, it includes:

• Structuring income to minimize global tax burden
• Timing of residency transitions
• Asset ownership and inheritance considerations
• Exit tax implications when leaving Türkiye

Strategic planning is especially important for high-net-worth individuals, executives, and foreign entrepreneurs with multi-jurisdictional exposure.

Social Security and Payroll Considerations

Expats working in Türkiye may also face social security obligations, depending on:

• Bilateral social security agreements
• Duration of assignment
• Local vs. foreign employment contracts

Correct payroll structuring ensures compliance while avoiding unnecessary contributions or penalties.

Ongoing Reporting and Audit Support

Tax obligations in Türkiye do not end with filing. Authorities may request additional documentation, explanations, or initiate audits. Our firm provides:

• Ongoing reporting support
• Representation before tax offices
• Audit defense and reconciliation services

Having a trusted local Istanbul accountant ensures continuity and responsiveness in all dealings with Turkish authorities.

Why Professional Local Expertise Matters

Turkish tax legislation is detailed, frequently updated, and strictly enforced. For expats and non-residents, language barriers and unfamiliar procedures increase risk. Working with a specialized Turkish accounting firm ensures:

• Full alignment with current legislation
• Accurate interpretation of international tax rules
• Efficient communication with authorities

Our multilingual team delivers tailored solutions under one roof, covering accounting, reporting, and advisory needs through integrated accounting services in Türkiye.
