Introduction
R&D tax incentives in Turkey are among the most important legal and financial tools available to innovative companies. Businesses operating in technology, manufacturing, software, biotechnology, pharmaceuticals, automotive, defense, electronics, artificial intelligence, machinery, medical devices, energy, chemicals and engineering may significantly reduce their tax burden if they carry out qualifying research, development, innovation or design activities under the applicable Turkish incentive regimes.
Turkey supports R&D and design activities mainly through Law No. 5746 on Supporting Research, Development and Design Activities, together with related corporate tax, income tax, VAT, customs and social security legislation. The Ministry of Industry and Technology identifies Law No. 5746 and the relevant regulations as the main legal framework for R&D and design centers.
The incentive package may include a 100% R&D and design deduction, income tax withholding support for qualifying personnel, employer social security premium support, stamp tax exemption, VAT exemption for machinery and equipment used in R&D and design projects, and customs duty exemption for imported goods used in R&D, innovation and design activities. PwC’s 2026 Turkey tax incentives summary lists these principal benefits under Law No. 5746, including 100% R&D deduction, income tax exemption rates of 95%, 90% or 80%, 50% employer social security premium support, VAT exemption for certain machinery and equipment, stamp tax exemption and customs duty exemption.
However, these incentives are not automatic. A company must determine whether its activities legally qualify as R&D, innovation or design. It must also obtain the required R&D center or design center approval where applicable, maintain project files, document personnel work, separate eligible and non-eligible expenditures, preserve invoices and payroll records, and comply with reporting and audit procedures. A company that treats ordinary production, routine software maintenance, standard testing, marketing activity or commercial adaptation as R&D may face denied deductions, tax assessments, penalties and repayment of incentives.
1. What Are R&D Tax Incentives in Turkey?
R&D tax incentives are tax and social security benefits granted to companies that conduct qualifying research, development, innovation or design activities. The policy objective is to increase technological capacity, support high-value production, encourage innovation, create qualified employment and improve Turkey’s competitiveness in international markets.
In practical terms, an R&D incentive allows a company to reduce its taxable base, reduce payroll tax cost, lower social security burden and reduce indirect tax cost on eligible R&D-related purchases. These benefits can be especially important for companies with high personnel costs, long product development cycles, technology investments or prototype expenses.
Turkey’s R&D incentive framework is especially attractive for companies that establish approved R&D centers or design centers. The official Ministry of Industry and Technology FAQ states that R&D and design centers may deduct 100% of their project-related expenditures from the corporate tax base.
This means that eligible R&D expenditure is not merely an accounting cost. It may also provide a tax deduction mechanism that improves the company’s after-tax position. For growth-stage technology businesses, manufacturers and exporters, this can materially affect cash flow and investment capacity.
2. Which Companies Can Benefit?
R&D incentives in Turkey may benefit a wide range of companies. These include technology startups, manufacturing companies, software companies, engineering firms, design businesses, pharmaceutical companies, medical technology companies, defense industry suppliers, automotive companies, machinery producers, electronics manufacturers, chemical companies and foreign-owned Turkish subsidiaries.
Foreign-owned companies may also benefit if they establish an eligible Turkish R&D or design center and satisfy the legal requirements. Turkey’s general investment incentives framework expressly includes R&D and design center incentives as support mechanisms for companies conducting R&D, innovation and design activities through approved centers.
The key point is that the company’s activity must be genuinely innovative or design-oriented. Merely being a technology company is not enough. A company must show that its projects involve research, development, technological uncertainty, innovation, product improvement, design development or qualifying technical work.
A software company developing a new artificial intelligence model, cybersecurity solution or cloud platform may qualify. A manufacturer developing a new production method, material, machine component or engineering solution may qualify. A design company developing original industrial design outputs may qualify. However, routine sales, ordinary production, basic customization, customer support, marketing, administrative work and standard quality control are generally not enough by themselves.
3. R&D Deduction: 100% Deduction from the Tax Base
The most important incentive is the R&D and design deduction. Under the incentive regime, eligible R&D and design expenditures may be deducted from the corporate tax base. PwC states that Law No. 5746 provides an R&D deduction of 100%.
This incentive can significantly reduce corporate tax liability. Turkey’s ordinary corporate income tax rate is generally 25% for ordinary companies, while certain financial sector companies are subject to 30%; therefore, deductions that reduce the corporate tax base can be financially meaningful for companies with substantial R&D spending.
Eligible expenditures may include R&D personnel costs, materials used in R&D, depreciation for eligible R&D assets, outsourced R&D services, general expenses directly connected with R&D activities, and other qualifying project expenditures. The exact scope depends on the legal framework, project type, accounting treatment and supporting documentation.
A company should not treat all technology-related expenses as R&D expenditure. Each cost must be linked to an eligible R&D or design project. Expenses related to ordinary production, sales, marketing, customer relationship management, distribution, after-sales services or general administration should be separated.
4. Income Tax Withholding Support for R&D and Design Personnel
Personnel costs are often the largest expense in R&D-intensive companies. Turkey therefore provides income tax withholding support for qualifying R&D, design and support personnel.
PwC’s 2026 Turkey tax incentives summary states that salaries of R&D, design and support personnel may benefit from income tax exemption at rates of 95%, 90% or 80%, depending on the personnel’s education and qualification level. Personnel with a PhD degree or a master’s degree in supported programs may benefit at the highest rate, while other categories benefit at lower rates. The exemption applies subject to the condition that salaries related to R&D or design activities do not exceed 40 times the gross minimum wage for the relevant period.
The 2025 amendments and application communiqués also clarified the implementation of income tax withholding support and stamp tax exemption for personnel working under Law No. 5746 and Law No. 4691; the Revenue Administration announced the relevant communiqué changes in September 2025.
This incentive requires employee-level tracking. A company should identify which employees are R&D personnel, design personnel, support personnel or ordinary administrative/commercial personnel. It should also document their qualifications, project assignments, working time, job descriptions and payroll calculations.
If an employee works partly on R&D and partly on commercial operations, the incentive should be applied only to the eligible portion where the law allows allocation. Companies should not apply the incentive to all employees simply because they work in an R&D center.
5. Social Security Premium Support
Another important benefit is employer social security premium support. PwC states that 50% of the employer portion of social security premiums for qualifying R&D, design and support personnel may be funded by the Ministry of Finance, subject to limits, including support personnel limits linked to full-time R&D and design personnel.
This support reduces the employer’s payroll cost and makes hiring qualified engineers, software developers, researchers, designers and technical personnel more affordable. For innovative companies, this can be decisive because R&D teams often require highly skilled employees whose salaries are above market averages.
However, the support must be applied carefully. The company must ensure that the employee is included within the eligible personnel list, that the work relates to approved R&D or design activities, and that social security declarations are made correctly. Misclassification may lead to correction, repayment and penalties.
6. Stamp Tax Exemption
R&D and design incentives also include stamp tax exemption. PwC states that documents prepared for R&D and design activities, including payrolls of R&D, design and support personnel, are exempt from stamp tax, again subject to the salary cap for payroll-related exemption.
This exemption can be useful because R&D companies sign many documents: project agreements, service contracts, collaboration agreements, personnel payrolls, supplier contracts, prototype development documents, grant agreements and university cooperation protocols. Stamp tax may seem small compared with corporate tax, but it can accumulate in high-value or document-heavy projects.
The exemption should be applied only to documents connected with eligible R&D, innovation or design activities. A commercial sales contract or ordinary distribution agreement should not automatically be treated as exempt merely because the company operates an R&D center.
7. VAT Exemption for Machinery and Equipment
R&D and design activities often require specialized machinery, laboratory tools, test equipment, servers, prototyping equipment, engineering devices, production trial equipment or design infrastructure. Turkey provides VAT exemption for certain machinery and equipment used in R&D, innovation and design projects.
PwC states that deliveries of machinery and equipment used for R&D, innovation and design projects by R&D centers are exempt from VAT.
This incentive improves cash flow. If a company purchases expensive equipment and pays VAT upfront, it may need to carry forward input VAT or wait for recovery. VAT exemption reduces this burden and makes capital investment easier.
However, the equipment must be genuinely used for eligible R&D, innovation or design projects. The company should preserve project approvals, invoices, fixed asset records, equipment lists, technical specifications and evidence showing how the equipment is used in qualifying projects.
8. Customs Duty Exemption for R&D Imports
Innovative companies may import specialized components, laboratory supplies, prototype materials, testing devices or engineering equipment that are not easily available in Turkey. Law No. 5746 also provides customs duty-related advantages for goods imported for use in R&D, innovation and design projects.
PwC states that goods imported for use in R&D, innovation and design projects are exempt from customs duties, and that related papers and transactions may also benefit from stamp tax and fee exemptions.
The exemption is valuable for companies in biotechnology, electronics, robotics, automotive R&D, defense technology, medical devices, clean energy and industrial engineering. Yet customs exemptions are documentation-sensitive. Imported goods should match project needs, customs classifications, import documents and internal R&D records.
If imported goods are later used for ordinary production, sold, transferred or not traceable, customs and tax risks may arise. Companies should build internal controls for imported R&D goods.
9. R&D Center and Design Center Approval
A company generally needs formal approval to operate as an R&D center or design center and benefit from the full incentive package. The Ministry of Industry and Technology’s official portal provides access to the laws, regulations and administrative framework for R&D and design centers, including Law No. 5746 and related regulations.
Approval is not merely symbolic. It creates the legal basis for applying the incentives. The company must satisfy personnel, project, physical space, reporting and documentation requirements. The Ministry of Industry and Technology’s FAQ confirms the availability of tax deduction benefits for R&D and design centers and reflects the project-based nature of the regime.
Before applying, a company should prepare its project portfolio, personnel list, technical infrastructure, organizational chart, physical location, accounting system and internal R&D procedures. A weak application may be rejected or may create later compliance issues.
10. What Activities Qualify as R&D?
Qualifying R&D activities usually involve creating new technical knowledge, developing new products, improving existing products, solving technological uncertainty, conducting experimental development, creating prototypes, developing new methods, improving production processes or generating innovative outputs.
Examples may include developing a new software algorithm, designing an advanced medical device, creating a new material, improving energy efficiency through a new engineering solution, developing a new production technology, creating a prototype machine, performing experimental tests for a new product, or developing an innovative industrial design.
Non-qualifying activities may include ordinary market research, sales activities, routine quality control, cosmetic changes, basic data entry, standard software maintenance, ordinary customer support, marketing campaigns, routine adaptation, administrative work and mass production without R&D content.
The classification of activities should be made carefully because tax authorities and Ministry auditors may examine whether the claimed R&D work is genuine.
11. Accounting Separation and Documentation
The success of an R&D incentive claim depends on documentation. Companies should maintain separate accounting records for eligible R&D and non-R&D activities. Eligible expenditures should be linked to specific projects. Payroll costs should be connected with personnel working on eligible projects. Equipment should be linked to R&D use.
A good R&D tax file should include:
Project approval documents.
Project descriptions and technical reports.
Personnel lists and job descriptions.
Timesheets or work allocation records.
Payroll records.
Invoices for R&D expenses.
Equipment and fixed asset records.
Outsourced service contracts.
Prototype and testing records.
Patent, utility model or design documents where relevant.
Accounting schedules separating eligible and non-eligible costs.
This documentation should be prepared contemporaneously. Documents created only after a tax audit begins are less persuasive.
12. R&D Incentives and Technology Development Zones
R&D incentives under Law No. 5746 should be distinguished from Technology Development Zone incentives under Law No. 4691. Both regimes support innovation, but they operate differently.
Technology Development Zones provide tax advantages for companies operating in technoparks, especially for eligible software, R&D and design income. Law No. 5746, on the other hand, supports approved R&D and design centers and specific R&D/design activities regardless of whether the company is located in a technopark.
Some companies may consider both options. For example, a software company may operate in a Technology Development Zone, while a manufacturer may establish an approved R&D center within its industrial facility. The correct choice depends on the business model, location, personnel structure, project type, income streams and long-term strategy.
Companies should not assume that the same expense can benefit from multiple incentives without limitation. Incentive overlap must be reviewed carefully.
13. R&D Incentives for Foreign Investors
Foreign investors can benefit from R&D tax incentives in Turkey if they establish a Turkish company or eligible Turkish operation that satisfies the applicable requirements. Turkey’s investment incentive framework expressly identifies R&D and design center incentives as a separate support mechanism for companies conducting R&D, innovation and design activities through approved centers.
This makes Turkey attractive for foreign companies seeking regional R&D hubs, engineering centers, software development teams, product localization units, prototype facilities or innovation centers.
However, foreign investors should coordinate R&D incentives with transfer pricing, intellectual property ownership, royalty payments, cost-sharing agreements and profit repatriation. If a Turkish R&D center develops valuable IP for a foreign parent company, the intercompany arrangement should reflect arm’s-length principles. The Turkish entity should be properly compensated for its functions, assets and risks.
14. R&D Incentives and Intellectual Property
R&D activity often leads to intellectual property, including patents, software, designs, trade secrets, technical know-how, algorithms, prototypes and engineering outputs. Companies should determine who owns the IP and how it will be commercialized.
If IP is developed by a Turkish R&D center but transferred to a foreign group company, transfer pricing and withholding tax issues may arise. If the Turkish company licenses IP to customers, royalty income and VAT issues should be reviewed. If the company files patents or design registrations, the documentation may strengthen the R&D incentive file.
A strong IP strategy improves both legal protection and tax defensibility. R&D incentives should therefore be coordinated with patent filings, software copyright records, employee invention rules, confidentiality agreements and intercompany IP policies.
15. R&D Incentives and Payroll Compliance
Payroll compliance is one of the most sensitive areas. Since income tax withholding support and social security premium support are employee-based, payroll records must be accurate.
Companies should verify:
Whether the employee is R&D, design or support personnel.
Whether the employee actually works on eligible projects.
Whether the employee’s education level supports the applied exemption rate.
Whether the 40-times-gross-minimum-wage salary cap is respected.
Whether working time is documented.
Whether social security declarations use the correct incentive codes.
Whether support personnel limits are exceeded.
Incorrect payroll application can lead to tax and social security corrections. Companies should conduct monthly payroll incentive reviews.
16. Common Mistakes in R&D Tax Incentive Use
The first common mistake is treating every technical expense as R&D. Not every engineering or software expense qualifies.
The second mistake is applying incentives before obtaining required approvals.
The third mistake is failing to separate eligible and non-eligible activities.
The fourth mistake is applying payroll incentives to employees who perform sales, marketing or administrative work.
The fifth mistake is not documenting working time and project allocation.
The sixth mistake is treating routine software maintenance as R&D.
The seventh mistake is failing to preserve invoices and technical reports.
The eighth mistake is applying VAT exemption to equipment not used in eligible projects.
The ninth mistake is ignoring transfer pricing when R&D is performed for foreign group companies.
The tenth mistake is preparing documentation only when an audit starts.
17. Practical Checklist for Innovative Companies
Before claiming R&D tax incentives in Turkey, a company should ask:
Does the company have an approved R&D center or design center where required?
Are the projects genuinely R&D, innovation or design projects?
Are project files complete?
Are eligible expenses separately recorded?
Are personnel roles and working time documented?
Are payroll incentives applied only to eligible employees?
Are support personnel limits observed?
Are VAT-exempt machinery and equipment used in eligible projects?
Are imported goods linked to R&D projects?
Are stamp tax exemptions applied only to relevant documents?
Are intercompany R&D arrangements arm’s length?
Is intellectual property ownership documented?
Can the company defend the incentive in a tax or Ministry audit?
This checklist should be reviewed before applying the incentives and updated every fiscal year.
18. Tax Audit and Ministry Inspection Risks
R&D incentives may be reviewed by tax authorities and relevant administrative bodies. The company may be asked to prove that the projects are real, the expenses are eligible, the personnel worked on qualifying activities and the incentives were calculated correctly.
Tax authorities may review corporate tax returns, payroll declarations, social security records, VAT exemption documents, invoices, fixed asset records, project files and accounting schedules. The Ministry may also examine whether the company continues to satisfy R&D or design center requirements.
If deficiencies are found, the company may face denied deductions, repayment of incentives, tax loss penalties, late-payment interest, social security corrections and administrative consequences.
Conclusion
R&D tax incentives in Turkey provide substantial legal and financial benefits for innovative companies. Under Law No. 5746, eligible companies may benefit from a 100% R&D and design deduction, income tax withholding support for qualifying personnel, 50% employer social security premium support, stamp tax exemption, VAT exemption for machinery and equipment used in R&D/design projects, and customs duty exemption for imported goods used in R&D, innovation and design activities.
These incentives can reduce corporate tax burden, improve cash flow, lower employment cost and support technology investment. They are particularly valuable for software companies, manufacturers, engineering firms, biotechnology companies, medical device producers, defense industry suppliers, automotive businesses and foreign investors establishing innovation operations in Turkey.
However, the regime requires disciplined compliance. Companies must obtain required approvals, classify projects correctly, separate eligible expenses, document personnel activity, comply with payroll rules, preserve VAT and customs exemption files, and prepare for possible tax or Ministry audits.
The safest approach is preventive planning. A company should design its R&D incentive system before claiming benefits. It should align legal, tax, accounting, HR, payroll, technical project management and intellectual property documentation. A properly managed R&D incentive structure can create meaningful tax savings and support innovation. A poorly documented structure may create tax assessments, penalties and loss of incentives.
For innovative companies operating in Turkey, R&D tax incentives should therefore be treated not merely as tax savings, but as a strategic legal framework for sustainable technology development, qualified employment and long-term competitive advantage.
