TAX OBLIGATIONS IN TURKEY FOR INDIVIDUALS EARNING INCOME ABROAD
The taxation of income earned in Turkey is, as a rule, carried out within a clear and predictable system, either through withholding at source or by means of an annual tax return. However, when it comes to income obtained from abroad, the necessity to evaluate factors such as the nature of the income, the place where it is earned, and the status of the taxpayer significantly complicates the taxation process.
With the involvement of international tax law, the question of which country’s legislation will apply arises; moreover, double taxation avoidance agreements (DTAAs) further deepen the technical dimension of the practice. In this context, even the smallest mistake may lead to serious tax penalties, default interest, and additional financial liabilities, making it of utmost importance to address the matter carefully and systematically.
WHAT ARE THE CONDITIONS FOR BEING A TAXPAYER IN TURKEY?
Tax liability in Turkey is a legal status determined based on how individuals or entities earn income and their connections with Turkey. The conditions for being a taxpayer are not solely dependent on earning income in Turkey; rather, they are shaped by a combined assessment of factors such as the place of residence, duration of stay, and the economic center of the individual.
In this context, the distinction between full tax liability (unlimited liability) and limited tax liability constitutes the foundation of the taxation regime, and the correct determination of taxpayer status directly affects both the scope of tax obligations and the declaration and payment processes. Therefore, a proper understanding of the conditions for being a taxpayer in Turkey is of great importance in preventing potential tax risks.
Distinction Between Full and Limited Tax Liability in Turkey
In the taxation of income earned abroad, the first and most critical step is to accurately determine the individual’s taxpayer status in Turkey, as the scope of tax liability varies directly depending on this status. In this regard, the question “Am I required to pay tax in Turkey?” requires a joint evaluation of fundamental concepts such as full tax liability, limited tax liability, place of residence, and type of income.
Under the Turkish tax system, for individuals, tax liability is divided into two categories: full tax liability and limited tax liability.
- Individuals subject to full tax liability are taxed in Turkey on their worldwide income, regardless of whether it is earned in Turkey or abroad.
- In contrast, individuals with limited tax liability are taxed only on income earned in Turkey.
Pursuant to the Turkish Income Tax Law:
- Individuals residing in Turkey,
- Turkish citizens working abroad on behalf of public institutions or organizations headquartered in Turkey,
are considered fully liable taxpayers in Turkey.
Therefore, the mere fact that a person is physically working abroad does not, by itself, eliminate tax liability in Turkey. Especially in digital and remote working models, incorrect assessment of taxpayer status may lead to serious tax risks.
The 183-Day Rule and the Residency Criterion in Determining Tax Liability
One of the most important criteria in determining tax liability is the place of residence (domicile) and, in connection with this, the 183-day rule.
Individuals who stay in Turkey for more than six months (183 days) within a calendar year are, as a rule, deemed to be residents in Turkey and fall within the scope of full tax liability. However, when calculating this period, it is also necessary to consider whether the stay in Turkey is temporary and linked to a specific purpose.
On the other hand, for individuals who actually live abroad but establish a company in Turkey or issue invoices from Turkey within the scope of self-employment activities, the question arises as to which country has the right to tax the income. At this point, two fundamental principles come into play:
- Residence (domicile) principle: The state where the individual resides has the authority to tax the individual’s worldwide income.
- Source principle: The country where the income is generated may assert the right to tax that income.
In cases where these two principles conflict, double taxation avoidance agreements (DTAAs) to which Turkey is a party come into effect, determining which state has the taxing rights.
Determination of The Type of Income In Taxation
Another key determining factor in taxation is the legal nature of the income earned. In practice, the most common distinction is whether the income qualifies as employment income (salary) or self-employment income.
Employment income refers to payments made to individuals who work under an employer and are affiliated with a specific workplace, and the legal framework of this relationship is defined by an employment contract under Turkish labor law.
In contrast, if an individual operates independently, works on their own behalf and account, and provides services, the income derived is classified as self-employment income. In such cases, the individual is responsible for declaring their income and personally fulfilling all tax obligations in Turkey. This distinction is particularly important for freelancers, consultants, and remote professionals providing services abroad, as the applicable tax regime, declaration obligations, and even the social security implications may vary depending on the nature of the income.
However, for certain professions operating on an international scale, taxation may involve a more complex structure. For example, the earnings of professional athletes are often based on contracts involving multiple countries, where both the place of performance of the service and the legal nature of the contract become decisive for taxation. Similarly, the wages and receivables of seafarers (maritime workers) are subject to special assessments, due to factors such as the flag of the vessel, the residence of the employer, and the fact that the work is performed in international waters.
In conclusion, the accurate taxation of income earned abroad depends on the correct legal determination of, first, the taxpayer status, second, the residency criteria, and finally, the type of income.
WHICH INCOMES ARE CONSIDERED FOREIGN-SOURCED INCOMES UNDER TURKISH TAX LAW?
One of the most common issues in the taxation of income earned abroad is the failure to correctly determine which income qualifies as “foreign-sourced income.” In Turkish tax law, this distinction is not based solely on which country the payment is made from; rather, it depends on criteria such as the legal source of the income, the place where the activity is performed, and the economic connection.
In general, for income to be considered foreign-sourced in Turkey, it must be linked to a foreign employer, client, investment instrument, or economic activity. However, it should always be noted that each specific case must be evaluated individually.
Taxation in Turkey of Remote Employees
If a person residing in Turkey works remotely for an employer located abroad, the income earned is, as a rule, classified as employment income (salary). In this case, if the individual is a full taxpayer, such income will be subject to declaration in Turkey pursuant to Article 7/3-a of the Income Tax Law.
However, since the employer is located abroad, withholding tax is generally not applied in Turkey, which results in the taxation responsibility being directly borne by the employee. Furthermore, the fact that the work is physically performed in Turkey strengthens the tax nexus with Turkey. Additionally, if the conditions set out in Article 23/14-a of the Income Tax Law are met, foreign-sourced salary income may be exempt from taxation in Turkey.
Beyond salaries, employment-related receivables such as severance pay, notice compensation, overtime pay, annual leave entitlements, reinstatement compensation, and wrongful termination compensation received by remote employees are also considered income and are subject to taxation in Turkey. This highlights that, alongside the protection of employee rights, the proper fulfillment of tax obligations is equally important in remote working models.
Taxation in Turkey of Freelancers Earning Income from Abroad
For individuals who independently provide services abroad, the income earned is generally classified as self-employment income. In this context, payments received from abroad for activities such as software development, design, content creation, and consultancy are considered taxable income in Turkey and must be declared accordingly. Such individuals are responsible for declaring their income through an annual tax return and for fulfilling all relevant tax obligations. The fact that the income is earned in foreign currency does not eliminate the tax liability.
Taxation Of Consultancy Fees Received From Abroad In Turkey
Consultancy services are also considered, by their nature, within the scope of self-employment activities. The fact that the service is provided to a foreign individual or entity does not change the tax nature of the income; it merely triggers the application of international taxation rules. In particular, the place where the service is performed—whether it is rendered physically in Turkey or abroad—is crucial in determining which country has taxing rights.
Taxation Of Foreign Stock Market Capital Gains In Turkey
Gains derived from buying and selling shares on foreign stock exchanges are classified under Turkish tax law as capital gains (value appreciation income). For fully liable taxpayers, such gains are subject to declaration in Turkey, within certain exemptions and thresholds. In these transactions, it is of utmost importance to correctly determine the purchase and sale prices, take into account exchange rate differences, and perform calculations in accordance with the relevant legislation.
Taxation Of Dividend Income In Turkey
Dividend (profit share) income obtained from foreign companies is treated as income from securities capital. For fully liable individuals, such income is taxed in Turkey under certain exemption and credit mechanisms. In particular, whether tax withheld abroad can be credited in Turkey must be evaluated separately under the provisions of double taxation avoidance agreements (DTAAs).
Taxation Of Crypto Asset Income Earned On Foreign Exchanges In Turkey
Although the taxation of crypto assets has not yet been subject to a clear and comprehensive legal regulation in Turkish law, in practice such income is generally assessed either as capital gains (value appreciation income) or as business income, depending on the nature of the activity. Income obtained through foreign cryptocurrency exchanges may also be subject to tax review in Turkey if the individual is a fully liable taxpayer. For this reason, it is of great importance that transactions are properly recorded and income is accurately reported.
Taxation In Turkey Of Income From Investment Funds
Income derived from foreign-traded ETFs and investment funds is classified either as dividend income or capital gains, depending on its nature. For fully liable individuals, the general rule is that such income must be declared in Turkey. In particular, factors such as the distribution structure of the funds, accumulating (reinvestment) models, and tax withholding mechanisms directly affect the taxation process.
Taxation In Turkey Of Income From Intellectual Property Rights
Income derived from the use or exploitation of intellectual property rights abroad—such as copyrights, patents, trademarks, and software licenses—is also considered foreign-sourced income in Turkey. Such income generally arises as royalty (licensing fee) income, and when these rights are utilized abroad, the income is regarded as foreign-sourced earnings for tax purposes.
Taxation In Turkey Of Foreign Inheritance Income
Inheritance and succession income obtained after the death of a person located abroad is considered foreign-sourced income in Turkey, depending on the location of the estate. Accordingly, the acquisition through inheritance of cash, movable, or immovable assets located abroad, without renouncing inheritance rights, is treated as the acquisition of foreign assets by succession. For fully liable taxpayers in Turkey, inheritance acquired through a will or any form of mortis causa disposition is generally not directly subject to income tax; however, income generated from these assets in the future may become subject to taxation in Turkey under Turkish Inheritance Law.
Taxation In Turkey Of Income Derived From Foreign Real Estate
Income arising from immovable properties located abroad—such as rental income and capital gains from the sale of such properties—is considered foreign-sourced income within the scope of Turkish real estate law transactions.
In the case of renting out a foreign immovable property, the income obtained is classified as real estate capital income (rental income) under Turkish Law. Similarly, if the property is sold, the resulting gain is taxed under certain conditions as a capital gain (value appreciation income). In addition, if any income is derived from encumbrances such as easements, usufruct rights, or habitation rights (e.g., servitude rights, right of residence, etc.) registered on such property, this income must also be considered foreign-sourced income in Turkey.
For individuals who are fully liable taxpayers in Turkey, such income is subject to declaration in Turkey. However, if tax has already been paid abroad on the same income, it may be possible to offset (credit) such taxes against Turkish tax liability under the relevant Double Taxation Avoidance Agreement (DTAA) between Turkey and the respective country.
The fact that income is foreign-sourced does not mean it is exempt from taxation in Turkey. On the contrary, for individuals subject to full tax liability, many types of foreign income give rise to an obligation of declaration and taxation in Turkey, provided that certain conditions are met.
In practice, the fact that the same income has already been taxed in another country does not automatically mean it will not be taxed in Turkey. For example, compensation awarded by a court decision due to medical malpractice (doctor error) may be taxed in the country where it is received. However, relying solely on such foreign taxation and failing to declare the income in Turkey may lead to tax loss penalties and criminal sanctions. In such cases, double taxation avoidance agreements, the legal nature of the income (e.g., what type of damage the compensation covers), and the relevant legislation must all be evaluated together.
For this reason, it is of utmost importance that each type of foreign-sourced income is individually analyzed from a legal perspective, and that tax obligations are determined accordingly.
SHOULD A TAX REGISTRATION BE ESTABLISHED IN TURKEY WHEN INCOME IS EARNED FROM ABROAD?
If the activity qualifies as business income or self-employment income, it is necessary to establish a company in Turkey or register for tax purposes, thereby formalizing tax liability status. In contrast, for certain exceptional and temporary types of income, different assessments may apply; however, this always requires an individual case-by-case evaluation.
For professionals providing services abroad in Turkey, it is not only the taxation of income that is important, but also the legal structure under which such income is generated. The chosen business model directly determines the tax burden, declaration procedures, deductible expenses, and administrative obligations. Therefore, whether an individual earning income from abroad is required to establish tax residency in Turkey must be assessed together with the nature and continuity of the income.
Individuals earning income from abroad may either establish a new company in Turkey or operate as a foreign company branch or liaison office. These options provide flexibility and various advantages in terms of tax planning.
In this context, the question “Which structure is the most tax-efficient in Turkey?” does not have a single universal answer. It must be evaluated separately for each case, taking into account factors such as business volume, income level, type of activity, and long-term business strategy. Failure to choose the correct structure may result in an increased tax burden as well as the emergence of significant tax risks in the future.
Comparison of Sole Proprietorship and Limited Company in Turkey
In Turkey, the two most common structures for individual activities are the sole proprietorship and the limited liability company.
In sole proprietorships, the profit is considered the income of the individual and is taxed progressively according to the income tax tariff. The most significant advantages of this model are that the establishment and closure procedures are relatively fast and low-cost, and accounting and administrative obligations remain more limited. For this reason, it provides a practical solution, especially for freelancers and newly established professionals.
In limited liability companies, however, the profit is generated within the legal entity and is subject to corporate income tax. If dividends are distributed to shareholders, dividend taxation also becomes applicable. On the other hand, the limited company structure may offer advantages in terms of corporate image, limited liability, and in certain cases tax planning opportunities.
Accordingly, for low and medium-scale individual activities in Turkey, a sole proprietorship is often a more economical structure, while as income levels increase and the business becomes more institutionalized, the limited company model may become more appropriate.
Home Office and Deductible Expenses
A significant number of professionals providing services abroad operate in a home office setting in Turkey. Turkish tax legislation allows, under certain conditions, the deduction of expenses incurred for the conduct of business from taxable income.
Within this scope:
- A portion of rent expenses,
- General utility costs such as electricity, water, natural gas, and internet,
- Computers, software, and office equipment,
may be considered deductible expenses, provided that they are directly related to the business activity and comply with the principle of proportionality.
However, it is important that such expenses are distinguishable from personal consumption and are properly documented and provable when necessary. Otherwise, such deductions may become subject to dispute during a tax audit in Turkey.
Is It Possible to Earn Income from Abroad Without Establishing a Company in Turkey?
Another frequently asked question in practice is whether individuals earning income from abroad can operate without establishing a company in Turkey. From the perspective of Turkish tax law, activities that are continuous in nature and carried out with the intention of generating profit are, as a rule, required to be conducted within a commercial or professional organizational structure. Therefore, individuals who regularly provide services abroad and earn income are generally expected to establish a sole proprietorship or register as a self-employed taxpayer, depending on the nature of their activity.
However, there may be exceptional cases regarding occasional (non-continuous) income. It should nevertheless be noted that such exceptions are interpreted narrowly in practice, and most activities are evaluated within the scope of continuity in Turkey.
If income is earned without establishing a company or fulfilling tax registration obligations in Turkey, such earnings may be treated as undeclared (informal) income, which can result in tax loss penalties, default interest, and other administrative sanctions.
In conclusion, for professionals working with foreign clients, determining the most appropriate business structure should not be based solely on tax rates, but should instead consider the continuity of the activity, income level, and legal risks together. A proper structuring ensures both tax efficiency and the prevention of potential disputes.
INCENTIVES THAT REDUCE THE TAX BURDEN ON FOREIGN-SOURCED INCOME IN TURKEY
Turkey aims to eliminate this issue through Double Taxation Avoidance Agreements (DTAAs) concluded with many countries. Within the scope of these treaties:
- Which type of income is taxed in which country,
- How taxing rights are allocated between states,
- How taxes paid abroad are taken into account in Turkey,
are all regulated in detail.
In practice, the most common method is the tax credit (offset) system, under which the tax paid abroad can be deducted from the tax calculated in Turkey, within certain limits. However, the amount to be credited cannot exceed the tax calculated in Turkey.
Therefore, if the same income is taxed in two countries, the relevant DTAA provisions must first be examined; taxing rights must be determined under the treaty, and if necessary, the foreign tax should be credited against Turkish tax liability.
Let us assume a taxpayer who is a full tax resident in Turkey provides remote services to a US-based company and earns a monthly income of USD 5,000. The developer performs the services from Turkey and earns this income as employment income without establishing a company structure.
In this case, the income is first classified under full tax liability in Turkey, meaning it must, in principle, be declared in Turkey. The developer reports this income through an annual income tax return in Turkey. At this point, the Turkey–United States Double Taxation Avoidance Agreement becomes applicable. Under this treaty, if the same income is taxed both in the US and in Turkey, double taxation is eliminated.
For example, assume the US company withholds 10% tax at source (withholding tax) on the payment. In this case, the developer may credit the tax withheld in the US against the income tax payable in Turkey.
The credit mechanism operates as follows:
- The total annual income is calculated and the Turkish income tax is assessed,
- The tax paid in the US (e.g., 10% withholding tax) is documented and deducted from the Turkish tax liability,
- This ensures that the same income is not taxed twice.
The critical point here is that the tax paid in the US must be properly documented and compliant with the provisions of the relevant treaty. Otherwise, the right to claim a tax credit may be denied.
In this scenario:
- The income is declared in Turkey,
- The tax withheld in the United States is credited,
- Taxation in Turkey is applied only to the remaining amount after the credit.
This example clearly demonstrates that in foreign-sourced income cases, it is not only the country where the income is earned that matters, but also the taxpayer’s obligations in Turkey. When correctly applied, DTAA provisions and the tax credit mechanism provide an important legal safeguard against double taxation.
HOW IS FOREIGN-SOURCED INCOME TAXED IN TURKEY?
In the taxation of income derived from abroad in Turkey, the theoretical framework is as important as the practical implementation of compliance obligations. Incorrect or incomplete reporting may lead to serious consequences such as tax loss penalties and administrative sanctions. This section addresses filing procedures, emerging income models, and key practical considerations.
Tax Return Filing Procedures for Foreign Income in Turkey
For income earned by individuals that has not been subject to withholding (stopage) taxation, filing an annual income tax return in Turkey is mandatory. In Turkey, this obligation is generally fulfilled in March of each year.
This requirement is not limited to foreign-sourced income; it also applies to domestic income. In fact, income that is not subject to withholding or that exceeds certain exemption thresholds must also be declared through an annual tax return in Turkey. Accordingly, income such as:
- Rental income,
- Gains arising from rental increases,
- Occasional (incidental) income,
- Under certain conditions, capital gains from Turkish stocks and investment funds,
must also be included in the annual declaration.
Foreign-sourced income such as salary, self-employment income, dividends, or capital gains must be included in the tax return for full tax resident individuals in Turkey.
During the declaration process:
- The type of income must be correctly classified,
- Income earned in foreign currency must be converted into Turkish Lira,
- If applicable, foreign taxes paid must be taken into account under the tax credit mechanism,
must be properly considered.
Tax returns can be submitted electronically through the Turkish Revenue Administration system, and the calculated tax is payable in two installments.
Taxation of New-Generation Foreign Income Models
With digitalization, new types of income have emerged. Although these are novel in form, they are generally classified under traditional tax categories such as self-employment income or business income. Therefore, correctly determining the legal nature of digital income is crucial for tax compliance.
For digital nomads, the most critical issue is the relationship between the place of physical work and tax residency. Individuals considered tax residents in Turkey are not exempt from Turkish tax obligations simply because they perform their work in different countries. If their place of residence and economic ties remain in Turkey, their worldwide income must still be declared in Turkey.
Income earned by YouTubers, influencers, and content creators from foreign platforms is also generally considered business or professional income and is subject to taxation in Turkey. Receiving income through a platform does not eliminate tax liability; on the contrary, when such income is earned regularly and systematically, it may require the establishment of a formal tax registration.
Similarly, income generated through artificial intelligence (AI) tools, online courses, and digital platforms is also taxable depending on the nature of the activity. In cases where income is earned on a continuous basis, tax registration and declaration of income become mandatory.
The common feature of these new-generation income models is that income is often earned from abroad and, in many cases, there is no withholding mechanism at source. Therefore, the obligation to declare lies directly with the taxpayer, making accurate determination and timely reporting of income critically important.
Key Considerations When Issuing Invoices For Foreign Clients From Turkey
Invoices issued for services provided abroad from Turkey must comply not only with tax legislation, but also with principles of international trade law and commercial practice. In this context, the following issues are particularly important:
- Currency denomination: Invoices may be issued in foreign currency; however, during the tax declaration process, the relevant amounts must be converted into Turkish Lira.
- Exchange rate differences: Differences arising between the invoice date and the collection date may, from a tax perspective, be treated as additional income or deductible expense items.
- Supporting documentation: Documents proving that the service was actually provided abroad and that payment was received must be retained. These may include bank transfer receipts, contracts between the parties, and platform records.
In particular, in order to benefit from the VAT exemption under the scope of export of services, it is crucial that the transaction can be clearly documented as being rendered to a foreign customer.
The correct taxation of foreign-sourced income depends not only on theoretical legal knowledge but also on the proper execution of declaration procedures and the maintenance of accurate accounting records. In this regard, taxpayers who fulfill their obligations timely and completely with respect to both traditional and new-generation income models will significantly reduce potential tax risks.
Does Not Bringing Foreign Income Into Turkey Eliminate Tax Liability?
One of the most common misconceptions in practice is the belief that income earned abroad is not taxable if it is not physically transferred into Turkey. However, under the Turkish tax system, especially for full tax resident individuals, taxation is based on the principle of “income realization”, not on the place where the money is held.
Therefore, income earned abroad and kept in foreign bank accounts must still be declared in Turkey, provided that the relevant conditions are met. The transfer of income into Turkey does not, in principle, determine whether a tax liability exists or not. Only in certain special exemption or incentive regimes may the transfer of income into Turkey be required as an additional condition.
WHAT ARE THE CONSEQUENCES OF NOT DECLARING FOREIGN-SOURCED INCOME IN TURKEY?
One of the most common problems in the taxation of foreign-sourced income is the failure to properly or fully comply with declaration obligations. Such situations may lead not only to unpaid taxes, but also to serious sanctions such as tax loss penalties, late payment interest, and administrative fines in Turkey. In addition, enforcement proceedings under Turkish execution and bankruptcy law may be initiated for collection purposes, and in certain circumstances, criminal proceedings for fraud-related offenses may also be brought against the taxpayer.
Tax Penalties Arising from Failure to Declare Foreign Income in Turkey
The sanctions provided under Turkish tax legislation are not only aimed at collecting unpaid taxes, but also at ensuring that taxpayers fulfill their obligations accurately and on time. The most common penalties in this context under Turkish tax law are explained below:
