R&D Center or Technopark? 2026 Incentive Comparison (Turkey)
Two Turkish incentive regimes, two different mechanics: Law No. 4691 (technopark) exempts the earnings, while Law No. 5746 (R&D center) deducts the expense. This 2026 comparison covers the corporate tax exemption to 31 December 2028, the 100% R&D deduction, payroll income-tax withholding incentives, employer social-security support, the venture-capital fund obligations (3% vs 2%), and the statutory ban on claiming both regimes for the same activity (Law 5746 Art. 4/5).
If you build software, develop games, or run R&D-intensive operations, Turkey offers two major incentive regimes: the Technology Development Zone (technopark, Law No. 4691) and the R&D center (Law No. 5746). On paper both are described as “tax breaks” — yet their logic is fundamentally different. One exempts your earnings; the other deducts your expense. Pick the wrong regime and you lose cash incentive and risk running into the double-benefit ban.
This piece is organized around three concrete questions: Which regime fits my operating model? Can I use both at once? Where is the net 2026 impact higher?

Two regimes, two different mechanics
Technopark (Law 4691) is a place regime: your company (or branch) must physically operate inside a Technology Development Zone. Earnings from software, design and R&D activities carried out in the zone are exempt from corporate and income tax until 31 December 2028 under Provisional Article 2 of Law No. 4691.
R&D center (Law 5746) is an organization regime: you establish a Ministry of Industry and Technology–certified R&D center at your own premises. There is no zone requirement; instead there is a minimum headcount threshold and project discipline. The logic of Law No. 5746 does not exempt earnings — it deducts R&D expenditure from the tax base.
💡 Note from Gökay GÜL — CPA perspective: The most practical question separating the two regimes is: “Can I concentrate my activity geographically at a single point?” If yes, and your revenue/profit density is high, technopark fits. If no — my team is distributed but my spend is large — the R&D center is more compatible.
Earnings exemption vs R&D deduction
The difference is where the incentive touches your financials.
Technopark — earnings exemption. The profit generated from revenue you produce in the zone is directly outside the tax net. The more your company earns, the larger the incentive. For a high-margin, low-cost SaaS or game studio, this is the strongest lever.
R&D center — R&D deduction. Under Article 3(1) of Law No. 5746, the entire (100%) amount of R&D and innovation expenditure is deducted in determining the corporate tax base (Corporate Tax Law Art. 10 / Income Tax Law Art. 89). In years where earnings are insufficient, the deduction carries forward to later years, uplifted by the revaluation rate. This is a more accessible advantage for companies that have not yet turned a profit but carry large R&D spend — for example, a game project with a long development cycle.
⚠ Risk warning: The technopark exemption covers only the earnings from activity conducted inside the zone. Services rendered outside the zone, sales/marketing revenue, and incidental income such as interest or FX gains fall outside the exemption. 2025 Revenue Administration rulings separately assess how FX differences arising in the technopark are treated in determining the non-exempt corporate income — this split must be structured into your accounting from the outset.
Payroll incentives: withholding and social security
The shared strength of both regimes is lowering the cost of qualified personnel — but the technical structures differ.
Income-tax withholding incentive (Law 5746, R&D center). For the portion of R&D and support personnel wages not exceeding 40× the gross minimum wage (TL 1,321,200 per month per employee for 2026), the income tax computed after deducting the minimum-wage exemption is terminated on the withholding return at 95% for PhD holders (or those with at least a master’s in a supported program area), 90% for master’s/bachelor’s holders, and 80% for others (Law 5746 Art. 3/2, as amended by Law No. 7555 dated 20/7/2025, in force 1/8/2025).
Social-security premium support (Law 5746). Half (50%) of the employer’s share of the social-security premium computed on the same wages is covered by the Treasury (Law 5746 Art. 3/3).
Technopark (Law 4691). Wages of R&D, design and support personnel working in the zone also benefit from the income-tax withholding exemption; the social-security support provision of Law 5746 expressly covers personnel whose wages are income-tax exempt under Provisional Article 2 of Law 4691.
🎯 Strategic note for multinational groups: In both regimes, the portion of support personnel (administrative, finance, HR) eligible for the incentive is capped at 10% of the total full-time R&D/design headcount (Law 5746 Art. 4/2). Structuring your team composition against this ratio directly affects the realized return of the incentive.
Fund obligations: 3% and 2%
Both regimes impose a venture-capital contribution above a certain threshold. These are not penalties but “give-back” conditions attached to the incentive.
- Technopark (Law 4691): Where exempt annual earnings exceed the threshold (TL 5,000,000 exempt earnings for FY 2026, Presidential Decree 10803, Official Gazette 31.12.2025), 3% of the earnings is channeled to a venture-capital fund / incubation / R&D purpose. (See our hub article for the detail and cap.)
- R&D center (Law 5746): From 1/1/2022, corporate taxpayers whose annual R&D deduction claimed on the return is TL 1,000,000 or more must transfer 2% of that amount to a passive temporary account and channel it to venture-capital funds investing in Turkey-resident entrepreneurs or to incubation-stage entrepreneurs. This obligation is capped at TL 20,000,000 per year (Law 5746 Art. 3/14).
If the transfer is not made, 20% of the deductible amount cannot be subject to the R&D deduction that year — i.e., part of the incentive is clawed back.
The critical rule: you cannot claim both
This is the most frequently overlooked point and the most expensive to get wrong. Article 4/5 of Law No. 5746 expressly provides that those benefiting from the deductions, exemptions, support and incentives under this Law cannot additionally benefit from Income Tax Law Art. 89/13, Corporate Tax Law Art. 10/1-ğ, and Provisional Article 2 of Law No. 4691.
The practical consequence: for the same activity and the same personnel, you cannot stack the technopark exemption on top of Law 5746 R&D-center incentives. The choice must be made according to the structure of the activity unit — some groups use the two regimes separately across different legal entities or activity units, but this requires disciplined transfer pricing and cost segregation.
⚠ Risk warning: Structures built on the assumption “we’ll take both” end up, on audit, with a double-benefit finding and tax loss. Settling the regime choice at the setup stage is far cheaper than correcting it later.
Comparison table
| Criterion | Technopark (4691) | R&D Center (5746) |
|---|---|---|
| Type of regime | Place (must be inside the zone) | Organization (your own premises) |
| Form of tax advantage | Earnings exemption (corporate/income) | R&D deduction (100% of expense) |
| Time limit | 31 Dec 2028 (Provisional Art. 2) | Open-ended (permanent regime) |
| Profit dependence | High — grows as you profit | Low — runs on expense, carries forward in a loss |
| Payroll withholding incentive | Yes (zone personnel) | Yes (80–95%, 40× min-wage cap) |
| Employer social-security support | Within scope | 50% (Art. 3/3) |
| Minimum headcount threshold | None (zone admission suffices) | Yes (FTE personnel threshold) |
| Fund / VC obligation | 3% of earnings (above threshold) | 2% of deduction (≥ TL 1M, cap TL 20M) |
| Both at once? | No — Art. 4/5 ban | No — Art. 4/5 ban |
Which profile fits which regime?
High-margin SaaS / license revenue (software, product company): Because the earnings exemption hits profit directly, technopark is generally stronger. If revenue can be produced inside the zone, net incentive peaks.
Long development-cycle, not-yet-profitable projects (game studio, deep tech): An earnings exemption is worthless without profit; the expense-based R&D center deduction — which carries forward even in a loss — creates value earlier. Once profitable, the regime can be re-evaluated.
Distributed/remote team, multiple locations: If the physical zone requirement is constraining, an R&D center is operationally more feasible.
Mixed structure (group of companies): It is possible to place different activity units in different regimes; but this demands cost-segregation and transfer-pricing discipline.
💡 Field note: In practice the most common mistake is making the decision by asking “which incentive is bigger?” The right question is: “Which regime’s conditions does my operating model meet with the least friction?” A bigger incentive whose conditions you cannot meet stays on paper.
FAQ
What happens when the technopark exemption ends in 2028? The exemption period in Provisional Article 2 of Law 4691 has been extended several times; 31/12/2028 is the current statutory limit. An extension requires legislation, and this date should be flagged as a review point in any incentive planning.
How many personnel does an R&D center require? The Law envisages 50 full-time-equivalent R&D personnel; the President is authorized to reduce this to 15 for certain sectors (Law 5746 Art. 4/6). The current threshold varies by your field of activity — confirm before setup.
If I can’t use both, can I switch? Yes. Switching regimes is possible, but must be planned so as not to breach the conditions of incentives already claimed in prior years. The timing of the switch (start of the accounting period) matters.
Can a foreign-owned company benefit from either regime? Yes; neither regime distinguishes by ownership structure. What matters is the nature of the activity and meeting the physical/organizational conditions.
Action list
- Can you concentrate your operating model at a single location? (Yes → technopark axis; No → R&D-center axis.)
- Over a 12-month projection, is profit or expense dominant? (Profit → exemption; expense → deduction.)
- Does the support-staff share of your team exceed 10%? If so, recompute the incentive return.
- Does your annual R&D deduction exceed TL 1M? If so, budget the 2% venture-capital obligation.
- Settle the regime choice at setup / start of period — the Art. 4/5 ban makes later correction expensive.
