Double Taxation in Sweden: 2026 Updated Legal Guide

How to avoid double taxation in Sweden? A comprehensive legal guide on Swedish tax residency, the Turkey-Sweden double taxation avoidance agreement, permanent establishment, dividends, interest, royalties, tax credits, and reciprocal agreement procedures.

Entrance

Double taxation in Sweden is one of the most critical issues in international tax law, particularly for Turkish citizens working in Sweden, entrepreneurs with companies in Turkey but doing business in Sweden, investors receiving dividends or interest income from Swedish companies, and individuals with assets in both countries. This is because both the source country and the country of residence can demand tax on the same income earned through cross-border transactions. This risk can lead to overpayment of taxes, misrepresentation, or missed tax refund opportunities if the agreement is not interpreted correctly. The Swedish Tax Administration also explicitly states that tax treaties and foreign tax credit rules are fundamental tools for preventing double taxation. (skatteverket.se)

The first key point regarding Sweden is the scope of tax liability. According to Skatteverket, have unlimited tax liability are subject to Swedish tax on all their income, regardless of whether it comes from Sweden or another country. The same institution states that all income must still be declared to the Swedish Tax Administration, even if there are exceptions in tax treaties or domestic law. Therefore, the approach of "my income was already taxed in Turkey, so I don't need to declare it in Sweden" is often legally incorrect. (skatteverket.se)

The same fundamental problem applies to Turkey as well. Individuals who are fully liable for tax in Türkiye are, as a rule, taxed on their worldwide income. Therefore, the risk of double taxation is real and tangible for individuals residing in Türkiye who earn income in Sweden, or vice versa. The legal solution to this risk lies in both domestic law and the tax treaty between the two countries. The agreement between Turkey and Sweden to avoid double taxation with respect to income taxes was signed on January 21, 1988, published in the Official Gazette for Turkey on September 30, 1990, and entered into force on January 1, 1991.

In this article, double taxation in Sweden, specifically in the context of Turkey-Sweden. First, I will explain the concept of double taxation and the logic of Swedish tax residency. Then, I will examine how the agreement allocates taxation rights for different types of income, the methods used to resolve double taxation, the most critical points for investors and companies, and finally, the mutual agreement procedure. (skatteverket.se)

What is double taxation?

Double taxation, simply put, is when two different states claim to tax the same income or earnings. This sometimes occurs simultaneously and on the same taxpayer; other times, it manifests as the source country withholding tax while the country of residence includes the same income in its annual declaration. Skatteverket states that tax treaties are designed precisely to prevent this double burden, and Sweden has signed numerous agreements with various countries for this purpose. (skatteverket.se)

The fundamental reason for the risk of double taxation is that states make tax claims based on different points of connection. One state might say, "The person resides in my country, therefore I tax their worldly income," while another state might say, "The income was born in my country, therefore I also tax it." Therefore, two main concepts stand out in international tax law: residency and source state. The Swedish Tax Administration's explanations of tax liability are based precisely on this framework. (skatteverket.se)

Tax treaties are not used to completely eliminate this conflict, but rather to first share the right to tax between states, and then to reduce the remaining double taxation through exemption or offsetting. Skatteverket's "Settlement of foreign tax" page also explicitly states that in most treaties, double taxation is resolved by offsetting the foreign tax in the resident state. (skatteverket.se)

Why is tax residency a determining factor in Sweden?

The first step in the double taxation debate in Sweden is determining the extent to which an individual or company is liable for Swedish tax. According to Skatteverket, unlimited tax liability can be taxed in Sweden on all their income. This rule applies not only to income originating in Sweden but also to income from Turkey or another country. The tax treaty is therefore of central importance for individuals with unlimited tax liability in Sweden, as it determines how to balance any potential tax rights in Turkey on the same income. (skatteverket.se)

In this context, the biggest practical mistake is the idea that "Sweden is not interested because the income comes from a foreign country." Skatteverket explicitly emphasizes that foreign income must still be declared, even if there is a tax treaty or an exception in domestic law. In other words, the treaty often changes the tax outcome, not the declaration obligation. Taxpayers who miss this distinction may face additional problems due to under-declaration, even though they have the right to avoid double taxation. (skatteverket.se)

The main function of the Türkiye-Sweden double taxation avoidance agreement

The main function of the Turkey–Sweden agreement is to determine which type of income will be taxed in which state and by what method double taxation will be settled. Türkiye's list of agreements in force as of 2025 officially indicates the entry into force date and implementation time of the Sweden agreement. Skatteverket also points to Sweden's current list of tax agreements, stating that these agreements are the primary source for resolving double taxation issues.

This agreement, in line with the logic of the classic OECD model, separates income types: real estate income, business profits, dividends, interest, royalties, self-employment income, wage income, honorariums, and other income are regulated in separate articles. For each type of income, the right to tax is first allocated; then, Article 23 explains how double taxation will be settled. Article 23 of the Turkish text specifically demonstrates that the two countries use different methods.

How to avoid double taxation on real estate income?

According to the Turkey-Sweden agreement, income derived by a resident of a contracting state from immovable property may be taxed in the state where the property is situated. This rule is included in Article 6 of the agreement and covers rental income and income from direct use. Therefore, rental income earned by a resident of Turkey from immovable property in Sweden, or income earned by a resident of Sweden from immovable property in Turkey, may primarily be taxed in the state where the property is situated.

This rule is very important for real estate investors because the general belief that income from real estate is taxed only in the country of residence is incorrect. The agreement grants a strong taxation authority in favor of the source state on real estate income. Subsequently, double taxation is eliminated by the state of residence through exemption or offsetting under Article 23.

Why is the concept of a business location so crucial to commercial profitability?

In Sweden, one of the most critical concepts for companies in terms of double taxation establishment. According to Article 7 of the Turkey-Sweden Treaty, the profits of an enterprise of a contracting state may be taxed only in the state in which it is resident, unless the enterprise carries on business through a permanent establishment situated in the other state. If a permanent establishment exists in the other state, then only the profits attributable to the permanent establishment may be taxed in that other state.

This rule is particularly important when companies based in Turkey establish projects, offices, personnel, warehouses, or regular representative structures in Sweden. The same agreement also explicitly states that one company controlling another does not, by itself, create a permanent establishment. This shows that shareholder relationships and the concept of a tax-related permanent establishment are not automatically the same thing. However, if there is a de facto fixed place of business, regular operation, or a dependent representative structure, the tax implications can change completely.

The practical conclusion is this: finding customers in Sweden is one thing, establishing a taxable permanent establishment in Sweden is another. However, many investors misinterpret this distinction. Once a permanent establishment is created, corporate tax, declaration, and accounting obligations may arise in Sweden. Therefore, a double taxation analysis regarding business profits should be conducted before company formation, focusing on the risk associated with establishing a permanent establishment.

How much tax can each country levy on dividend income?

Article 10 of the Turkey-Sweden agreement grants both the source state and the state of residence the right to tax dividend income; however, it limits the rate that the source state can apply. According to the agreement, if the beneficial owner of the dividend is a resident of the other state, the source state may apply withholding tax; however, the rate cannot exceed 15% if the company receiving the dividend directly holds at least 25% of the capital of the paying company, and 20% in all other cases .

This regulation is extremely important for investors. For example, if a company resident in Türkiye receives dividends from its subsidiary in Sweden, the applicable tax ceiling in the source state may vary depending on the shareholding ratio. Similarly, if an investor resident in Sweden receives dividends from a company in Türkiye, regardless of what Turkish domestic law says, the agreement limits the withholding tax to the specified ceilings. Subsequently, the state of residence applies the exemption or offsetting method according to Article 23.

The agreement also stipulates that an additional dividend-like tax may be levied on the profits of a company operating in a state through a permanent establishment, after the tax under Article 7 has been deducted; however, it is clear from the agreement text that this additional tax cannot exceed the upper limit set in Article 10. This detail is particularly important in discussions concerning branch profits and retained earnings.

What rules apply to interest income?

According to Article 11 of the agreement, interest arising in one contracting state and paid to a resident of the other contracting state may be taxed in the state of residence; however, the source state may also levy tax, and this tax 15% . The same article also provides for exceptions for certain interest paid to states or central banks: interest arising in Sweden and paid to the Government of Turkey or the Central Bank of the Republic of Turkey is exempt from Swedish tax, and interest arising in Turkey and paid to the Government of Sweden or the Sveriges Riksbank is exempt from Turkish tax.

This provision is important with regard to credit relationships, group company financing, bond yields, and cross-border debt restructuring. It is incorrect to consider interest income solely as money deposited into a bank account; income from government bonds and other debt-receivable relationships may also fall under this article. If there is a significant link between the receivable on which interest is paid and the business establishment located in the other state, the agreement also provides for a return to the business income regime under Article 7 instead of Article 11.

What is the tax limit for intangible rights fees?

Article 12 of the agreement grants a similar source state taxation authority with respect to royalties. Accordingly, royalties arising in one contracting state and paid to a resident of the other contracting state may be taxed in the state of residence; however, the tax levied by the source state 10% . The agreement text includes patents, trademarks, models, plans, secret formulas, know-how, and the right to use certain equipment within the concept of royalties.

This rule is particularly critical for technology licenses, software licensing, know-how agreements, and intergroup intellectual property payments. Whether a license payment is made in Türkiye or Sweden can sometimes directly affect the tax rate. Therefore, the main risk for investors is the incorrect identification of whether the payment is a service fee or a royalty. The agreement, when correctly classified, helps prevent double taxation by limiting the tax rate in the source state.

Board fees and foreign investors

One of the issues frequently encountered, but often overlooked, by foreign investors investing in companies in Sweden board members' fees. According to Skatteverket's SINK website, individuals living abroad who receive board members' fees from a Swedish company may be taxed under SINK on these fees; the company specifically states that these fees may be subject to SINK regardless of where the board duties are performed. The same website also adds that in some cases, tax treaties may result in exemptions in Sweden. (skatteverket.se)

Therefore, for Turkish investors investing in Swedish companies, payments such as director's fees or board fees, in addition to dividends, need to be analyzed separately. This is because these are neither dividends nor classic wage income; they may give rise to different tax categories and must be evaluated in conjunction with the relevant clauses of the agreement. (skatteverket.se)

How to resolve double taxation?

According to Skatteverket's "Settlement of foreign tax" page, in Sweden, double taxation settlement . The organization explicitly states that if the income is not exempt in Sweden, a settlement and/or deduction can be requested for taxes paid abroad; Sweden implements this under the rules of the Foreign Tax Credit Act. It is also noted that individuals residing in Sweden and working abroad can request a deduction from their Swedish tax by submitting documentation relating to the foreign tax paid. (skatteverket.se)

Article 23 of the Turkey-Sweden agreement establishes a more detailed structure, prescribing different methods for the two states. For Turkey, the general rule is that income taxable in Sweden is exempt in Turkey according to the agreement; however, the same article reverts to the offsetting method for specific incomes . Specifically, the article lists the earnings covered under Article 8, certain dividends, interest, royalties, certain capital gains, and certain director's fees as eligible for offsetting in Turkey. The same provision also states that the exemption rule for dividends received from a Swedish company applies only if a Turkish resident directly holds at least 10% of the Swedish company's capital and voting rights

Regarding Sweden, Article 23 generally a deduction system. According to the article, when a Swedish resident earns income that is taxable in Turkey under the agreement, Sweden allows a deduction from its own tax an amount equal to the tax paid in Turkey. However, an exemption mechanism is also provided on the Swedish side for certain business profits and some participation dividends. Therefore, the single-sentence statement "Sweden always applies the deduction, Turkey always applies the exemption" is incomplete; the method may vary depending on the type of income and circumstances.

Mutual agreement procedure in the Türkiye-Sweden agreement

One of the most critical safeguards in double taxation agreements the mutual agreement procedure (MAP). According to Article 25 of the Turkey-Sweden agreement, if a resident of a contracting state considers that the actions of one or both states have resulted in consequences not in accordance with the agreement, he or she may, without being bound by domestic remedies, bring the matter before the competent authority of the state of his or her residence. If the competent authority finds the objection justified and cannot provide a satisfactory solution, it shall negotiate with the competent authority of the other state to remedy the taxation not in accordance with the agreement.

The Turkish Revenue Administration's MAP guide also separately indicates the timeframes and application aspects regarding the Swedish agreement. According to this guide, applications on the Turkish side of the Swedish agreement are made within the timeframes stipulated in Turkish domestic law; on the Swedish side, the timeframes stipulated in Swedish domestic law apply, however, in cases arising from Turkish actions, the timeframes in Turkish legislation are also taken into account. The same guide also indicates that if a tax refund is to be requested as a result of the agreement reached with respect to Turkey, within one year . (Gib)

This mechanism is particularly important in disputes such as transfer pricing, place of business attribution, incorrect withholding, incorrect residency assessment, or different classifications of the same income by two countries. Many taxpayers only consider domestic appeals; however, in cases of double taxation contrary to agreement, the MAP mechanism can often be a more suitable tool.

The most common mistakes in practice

In Sweden, the most common mistake regarding double taxation is believing that the tax treaty eliminates the declaration requirement . However, Skatteverket explicitly states that unlimited taxpayers must declare all their income. In most cases, the treaty alters the tax outcome; it does not automatically eliminate the declaration obligation. (skatteverket.se)

The second major mistake is misclassifying income types such as dividends, interest, royalties, and service fees. In the Turkey-Sweden agreement, each of these income types is subject to different articles and withholding tax ceilings. While dividends have a 15%/20% limit, interest has a 15% limit, and royalties have a 10% limit; in the case of commercial profits, if there is no business establishment, the other state may not have the right to tax them. Misclassification can lead to unnecessarily high withholding taxes or incorrect offsetting calculations.

The third mistake is that investors underestimate place of business risk. If a company based in Turkey establishes a permanent place of business, a dependent representative, or a continuing project relationship in Sweden, taxation may not be limited to Türkiye alone. This is why Article 7 of the agreement is central.

Conclusion

In Sweden, the issue of double taxation is not merely a technical tax matter, but a strategic legal area with direct financial consequences, particularly for individuals with income, profit, and investment flows between Turkey and Sweden. Individuals with unlimited tax liability in Sweden may be required to declare their worldwide income; similarly, individuals residing in Turkey may face the risk of having that same income taxed in Turkey. This conflict is resolved by the Turkey–Sweden double taxation avoidance agreement, which has been in effect since January 1, 1991. (skatteverket.se)

The practical backbone of the agreement is clear: for real estate income, the state where the property is located may have taxing authority; for commercial profits, the source state may have taxing authority if there is a place of business; for dividends, the source state may have taxing authority limited to 15% or 20%; for interest, the source state may have taxing authority limited to 15%; and for royalties, the source state may have taxing authority limited to 10%. Subsequently, Turkey and Sweden eliminate double taxation through exemption and/or offsetting under Article 23. Even in the event of a dispute, the mutual agreement procedure under Article 25 provides an important safeguard mechanism.

Therefore, the most accurate approach for someone investing, working, receiving dividends, or running a company in Sweden is as follows: first, the tax residency and type of income must be correctly determined; then, the relevant clause of the agreement must be found; and finally, the declaration and offsetting mechanisms in Swedish and Turkish domestic law must be properly implemented. Even with an agreement in place, instead of expecting an automatic result, a separate legal analysis is necessary for each income item. Double taxation problems in Sweden can often be resolved; however, the solution is only truly effective if the provisions of the agreement are correctly understood and applications are submitted within the deadlines.
