Introduction
Intellectual property rights are among the most valuable assets in modern business. Patents, trademarks, software, copyrights, designs, utility models, know-how, trade secrets, algorithms, source code, databases, technical processes and brand systems can generate revenue through licensing, sale, transfer, franchising, SaaS subscriptions, royalty payments, technology service agreements and intra-group IP arrangements. In Turkey, the taxation of intellectual property rights requires careful legal and tax planning because the same transaction may trigger corporate income tax, withholding tax, VAT, reverse-charge VAT, transfer pricing, customs valuation, stamp duty and incentive rules.
The tax treatment depends on several factors: whether the IP owner is resident or non-resident, whether the payment is a royalty, service fee, software subscription or business profit, whether the IP is registered, whether the income arises from R&D or software activities, whether the IP is used in Turkey, whether a double taxation treaty applies, whether the parties are related, and whether the transaction is supported by proper documentation.
Turkey’s ordinary corporate income tax rate is generally 25% for companies outside the financial sector, while financial sector companies are generally subject to 30%. Resident companies are taxed on worldwide income, while non-residents are taxed only on Turkish-source income. Turkey has also applied a domestic minimum corporate tax mechanism from 2025, but certain exemptions, including Technology Development Zone exemptions and qualifying R&D/design allowances, are excluded from the minimum-tax base.
For IP transactions, one of the most important rules is withholding tax on royalties paid to non-residents. Turkish domestic law generally requires a Turkish payer to withhold 20% on royalty payments to non-residents, although double taxation treaties commonly reduce this rate, often to 10%, if treaty conditions are satisfied.
At the same time, Turkey offers important incentives for software and R&D-based IP, especially through Technology Development Zones and R&D/design legislation. Profits derived from eligible software activities or products developed through R&D in technoparks may be exempt from corporate income tax, and certain software and services developed in technoparks may also benefit from VAT exemption until 12 December 2028.
This guide explains how patents, trademarks and software are taxed in Turkey and what companies should check before licensing, selling, buying or developing intellectual property.
1. What Counts as Intellectual Property for Tax Purposes?
Intellectual property is a broad concept. For tax purposes, the most common IP rights include patents, utility models, trademarks, industrial designs, copyrights, software, databases, source code, trade names, know-how, technical formulas, secret processes, algorithms, integrated circuit topographies and commercially valuable technical information.
Turkish Industrial Property Law No. 6769 protects rights such as trademarks, geographical signs, designs, patents, utility models and traditional product names. The law’s stated purpose is to protect these rights and contribute to technological, economic and social progress.
Tax law does not always follow the same categories as IP law. For example, a software payment may be treated as a royalty, service fee, electronic service, business profit or mixed payment depending on what rights are granted. A trademark payment may be treated as a royalty. A payment for know-how may be treated as payment for commercial or scientific experience. A SaaS fee may be treated differently from a copyright license.
Therefore, the first step in IP taxation is classification. The contract title is not decisive. The tax authority will examine the legal rights transferred, the economic substance of the transaction, the use of the IP, the identity of the parties and the payment mechanism.
2. Corporate Tax on IP Income Earned by Turkish Companies
If a Turkish resident company owns patents, trademarks, software or other IP rights and earns income from them, that income is generally part of the company’s corporate income tax base unless a specific exemption applies. The ordinary corporate income tax rate is generally 25% for non-financial companies.
IP income may arise from:
Licensing a trademark to franchisees.
Licensing software to customers.
Selling source code or technology rights.
Receiving royalties for patents or utility models.
Transferring a registered design.
Charging SaaS subscription fees.
Receiving fees for know-how or technical processes.
Selling products manufactured with patented technology.
A Turkish company should record IP income separately where possible. This is especially important if the company claims technopark exemption, R&D incentives, patent box-style exemptions or transfer pricing positions. Mixed revenue streams can create audit risk. For example, a software company may have exempt software development income, taxable consulting income, taxable hardware resale income and royalty income subject to different treatment.
3. Patent Box and Industrial Property Rights Exemption
Turkey has a specific exemption for certain industrial property rights. Article 5/B of the Corporate Tax Law regulates an exemption for income derived from industrial property rights. Professional tax guidance summarizes that 50% of income derived from leasing, transfer, sale or serial production marketing of inventions created through R&D, innovation or software activities may be exempt, where statutory conditions are satisfied.
This exemption is particularly relevant for patents and utility models. It generally targets inventions resulting from R&D, innovation or software activities carried out in Turkey and protected by patent or utility model documentation. The exemption may apply to income from licensing the invention, selling the invention, marketing products produced through the invention, or selling products manufactured by using the patented invention.
However, the exemption is not automatic. A company must prove that the IP qualifies, that the invention is protected by patent or utility model rights, that the income is attributable to the qualifying invention, and that the statutory conditions are met. If only part of a product or production process is protected by patent or utility model, the exemption should be applied only to the portion of income attributable to the protected invention, not the entire product revenue.
For example, if a Turkish manufacturer sells a machine that includes one patented mechanism, the entire machine revenue should not automatically be treated as exempt. The company must determine the portion of profit attributable to the patented component or process.
4. Technology Development Zone Exemptions for Software and IP
Technology Development Zones, also known as technoparks, are highly important for software and R&D-based IP taxation in Turkey. Profits derived from software activities or products developed as a result of R&D activities in technoparks may be exempt from corporate income tax.
For income derived from the sale, transfer or lease of IP developed in technoparks, the relevant IP should generally be supported by patent or patent-equivalent documents, such as utility model certificates, design registration certificates, copyright registration certificates, integrated circuit topography certificates or similar documents. Contract-based R&D activities are treated differently because companies do not necessarily need IP registration for contract-based R&D activities to benefit from the corporate tax exemption.
Technopark companies may also benefit from VAT exemption on certain software and services arising from software development activities. The relevant categories include system management, data management, business applications, internet, games, mobile applications, sector applications and military command-control applications, with the exemption available until 12 December 2028.
This is highly relevant for SaaS companies, gaming studios, mobile app developers, enterprise software companies, cybersecurity firms and AI-driven software businesses. However, ordinary consulting, hardware resale, non-R&D services and unrelated commercial activities are not automatically exempt merely because the company is located in a technopark. PwC’s guidance expressly states that income from activities other than R&D and software income is subject to corporate income tax.
5. R&D and Design Incentives for IP Development
Companies developing IP in Turkey should also consider R&D and design incentives. Under Law No. 5746, eligible innovation, R&D and design expenditures made in R&D centers, design centers, technology centers or supported projects may be deducted from the corporate income tax base at a rate of 100%.
This is important because IP taxation is not only about taxing revenue after the IP is commercialized. It is also about reducing the cost of creating IP. A company developing patents, software, algorithms, industrial designs or technical processes may benefit from R&D deductions if the relevant conditions are satisfied.
The incentive regime may also include income tax exemption for qualifying R&D/design personnel, 50% employer social security premium support, VAT exemption for machines and equipment used in R&D/design projects, stamp tax exemption and customs duty exemption for goods imported for R&D, innovation and design projects.
A technology company should therefore build an integrated IP tax strategy: register IP where needed, classify income correctly, separate eligible and non-eligible revenue, document R&D expenses, protect source code and technical records, and align payroll incentives with project documentation.
6. Royalty Withholding Tax on Payments to Foreign IP Owners
Royalty withholding tax is one of the most important issues in cross-border IP transactions. If a Turkish company pays a foreign company for the use of patents, trademarks, software, copyrights, know-how, technical information or similar rights, Turkish withholding tax may apply.
Under domestic law, royalty payments to non-residents generally require 20% withholding tax by the Turkish payer. Double taxation treaties may reduce this rate, commonly to 10%, if the foreign recipient is treaty-resident, is the beneficial owner of the royalty and provides proper documentation.
Royalty payments may include:
Trademark license fees.
Patent royalties.
Software copyright license payments.
Know-how fees.
Franchise royalties.
Payments for secret formulas or processes.
Payments for technical or commercial experience.
Certain software license fees.
The Turkish payer should not wait until the end of the year to analyze withholding tax. The analysis should be done before payment. If withholding is not made when required, the Turkish tax authority may assess the unpaid tax, tax penalties and late-payment interest against the Turkish payer.
7. Double Tax Treaties and Reduced Royalty Rates
Turkey has an extensive double taxation treaty network. Many treaties reduce royalty withholding tax below the domestic 20% rate. PwC’s treaty table shows that many royalty treaty rates are 10%, while some treaties contain different rates depending on the type of royalty. For example, some treaties distinguish between copyrights, trademarks, patents, industrial equipment or scientific equipment.
Treaty relief is not automatic. The foreign IP owner must generally provide a valid certificate of tax residence. The recipient must also be the beneficial owner of the royalty. If the foreign company is merely a conduit entity that passes the royalty to another group company, treaty benefits may be challenged.
This is particularly important in IP holding structures. Multinational groups often own trademarks, software or patents through a foreign IP company. If the Turkish subsidiary pays royalties to that foreign company, the group should be able to prove that the foreign entity owns or lawfully controls the IP, has substance, assumes risks, controls the income and is not a paper intermediary.
8. VAT and Reverse-Charge VAT on IP Payments
VAT must be analyzed separately from withholding tax. Turkey’s general VAT rate is 20%, while reduced rates of 1% and 10% apply to certain categories. Deliveries of goods and services are subject to VAT, and Turkey applies a reverse-charge VAT mechanism for payments made by resident entities to foreign persons. Under this mechanism, the Turkish recipient calculates and pays VAT to the tax office and generally treats the same VAT as input VAT in the same month if deduction conditions are met.
IP payments to foreign licensors may therefore trigger reverse-charge VAT if the IP right or service is used or benefited from in Turkey. This may apply to software licenses, trademark licenses, patent licenses, know-how agreements, SaaS access, cloud software, technical support and foreign IP-related services.
A double taxation treaty may reduce royalty withholding tax, but it generally does not eliminate VAT. This is a common mistake. A Turkish company may correctly apply a 10% treaty royalty withholding rate but still fail to declare reverse-charge VAT. The two obligations are separate.
If the Turkish company has full input VAT deduction rights and enough output VAT, reverse-charge VAT may be largely cash-flow neutral. However, failure to declare it may still create penalties. If the company has exempt activities or insufficient output VAT, reverse-charge VAT may create a real cost or cash-flow burden.
9. Software Taxation: License, SaaS or Service?
Software is one of the most difficult areas of IP taxation. A software payment may be classified as a royalty, service fee, electronic service, SaaS subscription, copyright license, maintenance service or business profit depending on the rights granted.
A payment is more likely to be treated as a royalty if the Turkish customer receives rights to reproduce, modify, distribute, sublicense, commercialize or exploit software copyright. A payment may be closer to a service or subscription if the customer only receives limited access to a cloud-based platform for internal use.
However, Turkish tax practice can be cautious in software cases. Recent professional summaries of Turkish private rulings indicate that payments for computer software obtained from abroad may be treated under royalty provisions where software copyright use rights are involved, and treaty royalty provisions may reduce domestic withholding rates if the relevant conditions are met.
For software agreements, the contract should clearly state:
Whether the customer receives source code.
Whether the customer can copy or reproduce the software.
Whether sublicensing is allowed.
Whether the license is perpetual or subscription-based.
Whether maintenance and support are separate.
Whether the payment includes implementation services.
Whether the software is standard or customized.
Whether IP ownership remains with the provider.
Poor drafting can turn a simple commercial software purchase into a withholding tax dispute.
10. Trademark Royalties and Brand Licensing
Trademark licensing is common in Turkey in franchising, retail, consumer goods, cosmetics, food and beverage, hospitality, fashion, automotive services and e-commerce. A Turkish company may pay a foreign brand owner for the right to use a trademark, logo, trade name or brand system.
Trademark license payments are typically royalties. Therefore, payments to foreign trademark owners are generally subject to 20% domestic withholding tax unless a treaty reduces the rate. Some treaties have special provisions for trademark royalties, and at least some treaty notes distinguish trademarks from other forms of royalties.
Trademark royalties should also be supported by transfer pricing documentation where the parties are related. The Turkish licensee should prove that the royalty rate is arm’s length and that the trademark creates measurable business value. Evidence may include comparable royalty agreements, brand valuation, market studies, franchise agreements, benchmarking reports and profitability analysis.
A company should avoid paying high trademark royalties to a related foreign IP entity without evidence. The Turkish tax authority may disallow the excessive portion as disguised profit distribution through transfer pricing.
11. Patent Licensing and Patent Assignment
Patent licensing and assignment can create several tax consequences. A Turkish patent owner licensing a patent may earn royalty income subject to corporate tax unless an exemption applies. A foreign patent owner licensing a patent to a Turkish company may receive Turkish-source royalty income subject to withholding tax. A patent assignment may create capital gain or commercial income depending on the identity of the seller and the nature of the asset.
If the patent results from R&D, innovation or software activities in Turkey and the statutory conditions are met, the industrial property rights exemption may provide partial tax relief. If the patent is developed in a technopark, Technology Development Zone exemptions may also be relevant.
The agreement should clearly distinguish between license and assignment. A license allows use while ownership remains with the licensor. An assignment transfers ownership. The tax result, accounting treatment and legal formalities may differ.
Assignments of certain IP rights may also require written form, notarization or registration formalities under IP law. For example, professional IP guidance notes that patent assignment under Turkish IP Law must be in writing, signed by both parties and notarized before a notary public.
12. Know-How and Trade Secret Payments
Know-how and trade secrets are often more difficult to tax than registered patents or trademarks because they may not appear in public registries. However, payments for technical information, secret formulas, industrial processes, commercial experience or scientific experience are frequently treated as royalties under Turkish withholding and treaty rules.
A Turkish company paying a foreign company for manufacturing formulas, technical production methods, confidential algorithms, chemical processes, engineering documentation, recipes or industrial know-how should review withholding tax and reverse-charge VAT.
The contract should identify what is being transferred. If the payment is for general consulting, the tax treatment may differ from a payment for confidential know-how. If the agreement grants access to secret processes or commercial experience, royalty classification becomes more likely.
Documentation is essential. A company should preserve know-how transfer records, technical manuals, training materials, confidentiality clauses, delivery evidence, employee access records and business-use evidence.
13. Transfer Pricing in IP Transactions
Transfer pricing is central to IP taxation when related parties are involved. Turkish Corporate Tax Law includes transfer pricing rules based on OECD principles. If related-party transactions are not priced according to the arm’s-length principle, the related profits may be treated as disguised profit distribution and are not deductible for corporate income tax purposes.
IP transactions are particularly sensitive because intangible assets are difficult to value. A Turkish subsidiary may pay royalties to a foreign parent, license software from a group company, receive know-how from an affiliate, or pay brand fees to a foreign IP holding company. Each payment must be commercially justified and arm’s length.
A defensible transfer pricing file should include:
Description of the IP.
Legal ownership and economic ownership.
Functional analysis.
Development, enhancement, maintenance, protection and exploitation functions.
Royalty benchmarking.
Benefit analysis.
Comparable agreements.
Financial projections.
Contractual terms.
Evidence of actual use.
A royalty should not be deducted merely because it is included in an invoice. The Turkish licensee must prove that the payment is real, necessary, business-related and arm’s length.
14. Embedded Royalty Risk
Embedded royalty risk arises when a Turkish company imports goods or receives services from a related foreign party and the price includes the value of trademarks, brands or technology, but no separate royalty is stated. Turkish tax authorities may examine whether part of the payment should be recharacterized as a royalty.
KPMG commentary explains that the Turkish tax authority may challenge whether the transfer price of imported goods or intra-group services includes an embedded IP royalty, especially for trademarks and brands, and may seek to recharacterize part of the payment as royalty subject to withholding tax.
This issue is especially relevant for branded goods, luxury products, cosmetics, fashion, electronics, franchise supply chains, automotive parts and consumer goods. If the Turkish distributor pays high transfer prices for branded goods and no separate trademark royalty, tax authorities may ask whether the brand value is embedded in the goods price.
Companies should review supply agreements, distribution agreements, trademark licenses, customs valuation, transfer pricing studies and withholding tax positions together.
15. Customs Valuation and IP Royalties
IP royalties can also affect customs valuation. If imported goods are connected with licensed trademarks, patents, designs or know-how, customs authorities may examine whether royalty or license fees should be added to customs value. This can affect customs duty and import VAT.
For example, a Turkish company importing branded products while paying trademark royalties to a foreign brand owner may need to analyze whether the royalty is a condition of sale of the imported goods and whether it relates to those goods. If yes, customs value issues may arise.
This is why IP tax planning should not be limited to corporate tax and withholding tax. Customs, VAT and transfer pricing must be reviewed together.
16. Stamp Duty and IP Agreements
IP license agreements, assignment agreements, franchise agreements, software development agreements and technology transfer agreements may create stamp duty exposure if signed documents contain monetary amounts. Stamp duty should be reviewed before execution, especially for high-value contracts, long-term royalties, minimum guarantee clauses, milestone payments or penalty clauses.
A contract with a percentage-based royalty but no fixed amount may still require careful stamp duty analysis depending on the drafting. If the agreement states a minimum royalty, fixed license fee, guaranteed payment, penalty or purchase price, stamp duty may become more predictable and potentially significant.
The tax clause should identify who bears stamp duty and other transaction taxes.
17. Taxation of IP Sales
The sale of IP rights may be taxed differently from licensing. A sale or assignment transfers ownership. The seller may recognize gain. If the seller is a Turkish company, the gain is generally part of corporate taxable income unless an exemption applies. If the seller is non-resident, Turkish-source income and treaty rules should be reviewed.
For patents and utility models, the industrial property rights exemption may be relevant if the conditions are met. For software developed in technoparks, Technology Development Zone exemptions may be relevant. For trademarks, ordinary corporate tax rules may apply unless a specific incentive applies.
The sale agreement should clearly define what is transferred: source code, documentation, patents, trademark registrations, domain names, customer data, know-how, copyright, design files, databases, or only limited rights. The tax treatment depends on the assets transferred.
18. IP Holding Companies and Turkish Tax Risks
Some groups establish IP holding companies outside Turkey to own trademarks, software or patents and charge royalties to Turkish operating companies. This may be legitimate if the IP holding company has real substance, legal ownership, economic control, personnel, decision-making capacity and commercial purpose.
However, IP holding structures are high-risk if they are artificial. Turkish tax authorities may challenge treaty benefits, beneficial ownership, transfer pricing, royalty deductibility and withholding tax treatment. Controlled foreign company rules may also become relevant for Turkish resident shareholders of low-taxed passive IP entities.
A robust IP holding structure should include:
Real legal ownership of IP.
Development and maintenance functions.
Substance in the IP jurisdiction.
Board decision-making.
Valuation and benchmarking.
Beneficial ownership evidence.
Treaty documentation.
IP registration records.
Transfer pricing documentation.
Without substance, the structure may be treated as a tax avoidance arrangement.
19. Documentation for IP Tax Compliance
Documentation is the strongest defense in IP taxation. A company should maintain:
IP registration certificates.
Patent, trademark and software ownership records.
License agreements.
Assignment agreements.
Source code records.
R&D project files.
Technopark project approvals.
Invoices and payment records.
Royalty calculations.
Withholding tax returns.
VAT reverse-charge returns.
Tax residency certificates.
Transfer pricing reports.
Benchmarking studies.
Evidence of actual IP use.
Board approvals.
Customs files where imported goods are connected with IP.
The documentation should be prepared before or during the transaction. Documents prepared only after a tax audit begins are less persuasive.
20. Common Mistakes in IP Taxation in Turkey
The first common mistake is treating every software payment as a simple service fee without reviewing royalty risk.
The second mistake is applying treaty royalty rates without obtaining a certificate of residence.
The third mistake is paying royalties to foreign related parties without transfer pricing support.
The fourth mistake is failing to declare reverse-charge VAT on foreign IP payments.
The fifth mistake is assuming technopark location exempts all company income. Only eligible software and R&D income can benefit.
The sixth mistake is applying patent-related exemptions to the entire product revenue when only a component or process is patented.
The seventh mistake is ignoring embedded royalty risk in imported branded products.
The eighth mistake is failing to review customs valuation when royalties relate to imported goods.
The ninth mistake is drafting IP agreements without clear tax clauses.
The tenth mistake is failing to register or document IP ownership before claiming tax benefits.
21. Practical IP Tax Checklist
Before entering into an IP transaction in Turkey, a company should ask:
What IP right is involved: patent, trademark, software, know-how, design or copyright?
Is the transaction a license, assignment, service, SaaS subscription or mixed agreement?
Is the IP owner resident in Turkey or abroad?
Does Turkish withholding tax apply?
Is a double taxation treaty available?
Has a certificate of residence been obtained?
Is the recipient the beneficial owner?
Does reverse-charge VAT apply?
Can the Turkish recipient deduct the VAT?
Is the payment deductible for corporate tax purposes?
Are the parties related?
Is transfer pricing documentation required?
Does the IP qualify for technopark exemption?
Does Article 5/B industrial property rights exemption apply?
Is the IP properly registered?
Is the income attributable to eligible IP?
Does customs valuation need review?
Does the agreement create stamp duty?
Can the company defend the transaction in a tax audit?
Conclusion
Taxation of intellectual property rights in Turkey requires integrated legal and tax planning. Patents, trademarks and software can generate valuable income, but they also create complex tax obligations. Turkish resident companies earning IP income are generally subject to corporate income tax unless a specific exemption applies. The ordinary corporate income tax rate is generally 25% for non-financial companies, while financial sector companies are subject to 30%.
Cross-border IP payments are particularly sensitive. Royalty payments to non-residents generally require 20% withholding tax under domestic law, although double taxation treaties often reduce the rate, commonly to 10%, if the foreign recipient is treaty-resident and beneficial owner. VAT must be reviewed separately: Turkey’s reverse-charge VAT mechanism requires Turkish resident recipients to calculate and declare VAT on payments to foreign persons, with potential input VAT offset where conditions are met.
Turkey also offers valuable incentives for IP created through R&D and software activities. Technopark profits derived from software activities or R&D-developed products may be exempt from corporate income tax, and certain technopark software and services may benefit from VAT exemption until 12 December 2028. Article 5/B provides a patent box-style exemption for certain industrial property rights, commonly summarized as a 50% exemption for qualifying income from inventions created through R&D, innovation or software activities.
The safest approach is preventive compliance. Companies should classify IP payments correctly, draft clear license and assignment agreements, obtain treaty documents before payment, declare withholding and VAT properly, prepare transfer pricing files for related-party royalties, register IP where necessary, separate eligible and non-eligible income, and preserve audit-ready evidence.
A well-structured IP tax strategy can protect profits, support innovation and reduce tax risk. A poorly structured transaction may create withholding tax assessments, denied deductions, VAT liabilities, transfer pricing adjustments, customs valuation disputes, stamp duty exposure and loss of incentives. For this reason, IP taxation in Turkey should be treated as a strategic legal issue, not merely an accounting entry.
