As remote work becomes the global standard, many Turkish residents working for international companies—such as those based in Finland—are questioning their tax obligations. Specifically, is a salary received in foreign currency from a non-resident employer exempt from Turkish Income Tax, or is an annual tax return mandatory? This guide is based on the advance tax ruling dated April 18, 2023, issued by the Yozgat Provincial Treasury. It examines the tax status of an expert providing green building certification and life-cycle assessment services from Türkiye to a Finnish firm. Case Summary: The “Finnish Engineering” Scenario A specialist residing in Türkiye works full-time for a company headquartered in Finland. The relationship is strictly employer-employee: The employee follows a set weekly schedule and employer instructions. The company’s software infrastructure and guidelines are used. The salary is paid in foreign currency from Finland. The employer has no legal or business center in Türkiye. The ruling evaluates whether this income qualifies for the “Foreign Currency Wage Exemption” under Article 23/14-a of the Turkish Income Tax Law (GVK). Defining the Income: Wage vs. Self-Employment The ruling first establishes that the income is a “wage”, not self-employment income. This classification is based on the subordination factor: working under instructions, following a set schedule, and using employer-provided systems. This distinction is vital because it opens the door to wage-specific exemptions under GVK 23/14-a. Mandatory Conditions for Tax Exemption According to GVK 23/14-a and the ruling, a foreign currency salary is exempt from income tax ONLY if the following five conditions are met simultaneously: Non-Resident Employer: The employer must be a limited taxpayer (dar mükellef) with no legal or business headquarters in Türkiye. No Local Revenue: The employer must not engage in any activities that generate income within Türkiye. Foreign Earnings: The salary must be paid out of the employer’s profits generated outside of Türkiye. Foreign Currency: The payment must be made in a foreign currency (USD, EUR, etc.). No Local Expense Claim: The salary must not be recorded as an expense in any accounts or tax filings in Türkiye. Crucial Warning: If the foreign employer has even a small income-generating operation in Türkiye, the exemption is voided, and the employee must file an annual income tax return. The Türkiye-Finland Double Taxation Agreement (DTA) The ruling also references the Türkiye-Finland DTA. Under the treaty: If the service is performed remotely from Türkiye, the taxing right belongs to Türkiye. If the service were performed physically in Finland, taxing rights would depend on the “183-day rule” and whether the salary is paid by a Finnish permanent establishment. Since the expert works from home in Türkiye, the domestic GVK 23/14-a rules remain the primary legal framework. When Do You Need to File a Tax Return? If the exemption criteria (especially the “no local activity” rule for the employer) are not met, the income is taxable. Under GVK Article 95, the employee must: Declare the total annual income via an Annual Income Tax Return. Pay tax based on the progressive tax brackets in Türkiye. Note that since there is no local employer to perform withholding, the burden of declaration lies entirely on the employee. FAQ Table: Remote Work and Foreign Currency Wages Question Answer Is my USD/EUR salary from abroad tax-exempt? Yes, if your employer is a non-resident, has no business in Türkiye, and pays you from foreign profits. What if my employer starts selling services in Türkiye? You lose the exemption and must file an annual tax return (GVK 95). Is receiving the money in FX enough for exemption? No. The source of the money and the employer’s status are equally critical. Why is my income called a “wage”? Because you work under an employer’s direction, use their tools, and follow their schedule. What is a “Non-Resident Employer”? A company with no legal or business headquarters registered in Türkiye. Do I have to pay tax in Finland too? Generally no, if you perform the work in Türkiye, per the DTA. How do I prove the exemption if audited? By showing your contract, proof of FX payment, and documenting the employer’s lack of activity in Türkiye. What happens if I don’t file a return for non-exempt income? You may face tax assessments plus late payment interest and penalties. Does this apply to freelancers? No; freelancers are usually “self-employed” and fall under different rules (like GVK 20/B or 89/13). What is the most critical check for remote workers? Confirming that your foreign employer has zero revenue-generating activity in Türkiye. Legal Notice: The information in this article is intended for information purposes only.
