Technopark, R&D Centre, or QSC? A 2026 Decision Guide for Software and Game Studios in Turkey

Send the same software company through three different doors and three different tax outcomes come out. One game studio enters a technopark and exempts all of its income from tax; the neighbour sets up an R&D Centre in its own office and deducts its tax base only by the amount of R&D spending; a third serves the foreign group company and, as a Qualified Service Centre, deducts 95% of its income from the base. All three say “I’m using an incentive” — but what they receive is not the same, and one cannot stand in for another.

Regulatory Note: This article was prepared as of 9 July 2026 on the basis of Law No. 4691 on Technology Development Zones (Provisional art.2), Law No. 5746 on the Support of Research, Development and Design Activities (art.2, art.3, art.4/5), Corporate Income Tax Law No. 5520 (art.5/3, art.10/1-(j), art.32/C, Additional art.6) and the Qualified Service Centre regime introduced by Law No. 7582 dated 21/5/2026 (PITL art.23/1-(20), Income Tax General Communiqué No. 334). Because the Ministry of Industry and Technology implementation regulation for the QSC has not yet been published, some details of that regime will be settled by the regulation. Always take your concrete decision with your advisor.

The 60-Second Summary

The three are not the same mechanism. Technopark = a zone income exemption (100%, until 31/12/2028); R&D/Design Centre = a tax-base deduction by the amount of R&D spending (not an exemption); QSC = a deduction on foreign-service-centre income (100% inside the Istanbul Finance Centre / an eligible industrial zone, 95% outside, over 20 accounting periods).
The zone requirement exists only at the Technopark. The R&D Centre is set up in your own office — but it demands a headcount threshold: for an R&D centre the statute requires 50 full-time-equivalent staff, reducible to 15 by Presidential decision on a sectoral basis; 10 for a design centre. Technopark has no minimum headcount; even a single developer qualifies.
Exemption ≠ deduction. Under a Technopark exemption you cannot offset the loss against other income — it burns (CITL art.5/3). An R&D Centre deduction, when income is insufficient, carries forward to later years and grows with the revaluation rate. The cash-flow timing is diametrically opposite.
You cannot take both. Law 5746 art.4/5 bans a taxpayer using the R&D incentive from also using the 4691 Technopark exemption on the same income. For a QSC operating in the Istanbul Finance Centre, the staff wage exemption runs either through the IFC or through PITL art.23/1-(20) — they do not stack (Law 7582 art.12).
If you are in a large group, look at Pillar Two. In a multinational group with consolidated revenue above 750 million euros, if the income exemption pulls the effective rate below 15% a top-up tax (QDMTT) arises (CITL Additional art.6). A local/mid-sized firm is below this threshold; all three incentives run at full strength.

Three Regimes, Three Questions: WHERE / HOW MANY / WHAT DO YOU EXPORT

In the market these three regimes are described as if they were a staircase: “first enter a technopark, then become an R&D Centre when you grow.” Wrong frame. These are not steps of one staircase but three separate answers to three separate questions. Choosing the right regime begins with choosing the right question.

WHERE do you sit? → Technopark (Law 4691 Provisional art.2). The heart of this regime is location. Income of income- and corporate-tax payers physically operating within the boundaries of a technology development zone, derived exclusively from software, design and R&D activities in that zone, is exempt from income and corporate tax until 31/12/2028. The word “exclusively” is critical: income produced outside the zone or unrelated to it does not fall within scope. There is no minimum headcount — a one-person studio qualifies. But you must meet the physical zone requirement.

HOW MANY do you employ? → R&D / Design Centre (Law 5746). Here it is not location but headcount that decides. An R&D centre is set up in a separate unit of a capital company whose legal and business centre is in Turkey, with at least 50 full-time-equivalent R&D staff under the statute; the President may reduce this number to 15 on a sectoral basis (art.4/6). For a design centre the threshold is at least 10 full-time-equivalent design staff. There is no zone requirement — you set it up in your own office. In return you receive not an income exemption but a tax-base deduction on spending.

WHAT do you export? → Qualified Service Centre / QSC (CITL art.10/1-(j)). The new player of 2026. For corporations operating as a qualified service centre within the scope of Foreign Direct Investment Law No. 4875, 95% of the income they derive from abroad exclusively within the scope of these activities is deducted from the corporate tax base; for QSCs holding participant status in the Istanbul Finance Centre or in industrial zones deemed eligible by the President the rate is 100%. The definition of a QSC is narrow: a capital company serving a group of related companies actively operating in at least 3 different countries, deriving at least 80% of its annual revenue from related companies abroad. This definition targets not an independent local game studio but the multinational group’s service hub in Turkey.

Three questions, three different firm profiles. Now let us put it into numbers.

The Numbers: One Firm, Three Regimes

Let us set up a sample software company: annual revenue 100,000,000 TL, expenses 60,000,000 TL, gross corporate income 40,000,000 TL. The general corporate tax rate in 2026 is 25%. Let us run the same 40-million income through the three regimes separately and see what comes out. (Warning: these cannot be taken at once — under the Law 5746 art.4/5 ban, the table shows what would happen if the firm entered each regime separately.)

Item	No incentive	Technopark (4691)	R&D Centre (5746)	QSC (CITL 10/1-j)
Gross corporate income	40,000,000	40,000,000	40,000,000	40,000,000
Tax mechanism	—	Income 100% exempt	R&D spending (25,000,000) base deduction	Foreign income 95% deduction
CIT base	40,000,000	0	15,000,000	2,000,000
Corporate tax (25%)	10,000,000	0	3,750,000	500,000
Additional obligation	—	3% fund: 1,200,000 (locked in equity)	2% fund: 500,000 (locked in equity)	Must transfer income to Turkey
Personnel side	—	In-zone wage PIT exemption	Withholding 95/90/80 + SSI employer 50%	Wage PIT exemption (3/5× the minimum wage)

Simulation notes.

Technopark: if all of the 40M income comes from zone activity, CIT is zeroed. But because the exempt income exceeds 5,000,000 TL, an obligation to set aside a 3% venture capital fund arises: 40M × 3% = 1,200,000 TL (annual cap 100,000,000 TL; Presidential Decision No. 10803 dated 31/12/2025). This is not a tax but an investment obligation locked in equity — but if it is not invested, a loss of exemption entitlement of 20% of the amount that should have been transferred plus a tax-loss penalty arises.
R&D Centre: the deduction is not the whole income but the amount of R&D/design spending made. On the assumption of 25M TL R&D spending the base drops to 15M. In addition, withholding remission (95/90/80 on the portion of wages up to 40 times the gross minimum wage) and half of the SSI employer premium are covered from the state budget. Because the annual R&D deduction exceeds 1M TL, a 2% fund (cap 20M TL) applies — a separate and different mechanism from the Technopark’s 3%/5M/100M fund.
QSC: valid only if all of the 40M income comes from related companies abroad. The 95% deduction drops the base to 2M; had you been in the IFC it would have zeroed with 100%. Condition: bring the income to Turkey by the date of filing the annual CIT return.

What the table really tells you is that there is no single “best” row. Technopark gives the lowest tax but demands a physical zone and a 3% fund. The QSC gives almost zero tax but only a narrow profile (foreign group service) can enter. The R&D Centre sits in the middle — the tax advantage looks smaller, but its real strength is in personnel cost and loss flexibility. The legal basis of that flexibility is the next heading.

Exemption or Deduction? Where the Loss “Burns”

This is the most technical and most overlooked difference among the three regimes. “Income exemption” and “tax-base deduction” sound the same; in cash flow they produce diametrically opposite results.

An income exemption (Technopark, QSC) takes income out of tax directly. Its hidden cost is this: a loss from the exempt activity cannot be offset against non-exempt corporate income. The wording of the law is clear — Corporate Income Tax Law art.5/3: “The expenses relating to income exempted from corporate tax, or the losses arising from exempt-scope activities, shall not be allowed to be deducted from non-exempt corporate income.” So if your game project in the technopark makes a loss, you cannot deduct that loss from the company’s out-of-zone revenues (advertising, interest, hardware sales). Both the loss and the tax shield that would have come with it burn.

A tax-base deduction (R&D Centre) does the opposite. R&D/design spending is treated as a deduction in determining income; if income is insufficient that year the deduction entitlement is not lost — it carries forward to later accounting periods and is carried up by the revaluation rate under the Tax Procedure Law. A development year spent at a loss accumulates a “deferred tax asset” that will zero the tax of future profitable years.

The choice here depends on where the firm stands — not wordplay but a matter of timing. For an early-stage game studio with a high burn rate that spends its first years at a loss, the R&D Centre model makes sense: it accumulates the deduction indexed and uses it once it turns profitable. For an already profitable, mature studio, Technopark delivers cash immediately through an instant exemption. One invests in the future, the other rescues the present.

Decision Tree: Which Firm for Which Regime

Go through four questions in order; your first “yes” gives you your roadmap.

Does the bulk of your income come from related group companies abroad (at least 3 countries, 80%+ of revenue)? If yes → QSC (CITL 10/1-j). 100% if you are in the IFC or an eligible industrial zone, 95% otherwise. If you sell to independent customers — if you are not a group affiliate — you cannot fall within this definition; move to question 2.
Can you physically enter a technopark, and will your income be produced there? If yes and the firm is profitable → Technopark (4691). Lowest tax, lowest operational complexity. Even a single developer qualifies; do not forget the 3% fund.
Is your headcount above the threshold (50 in the statute, reducible to 15 on a sectoral basis; 10 for design) and do you want to work outside a zone / in your own office? If yes → R&D / Design Centre (5746). Especially for firms not yet profitable, personnel-heavy, developing long-cycle projects, the deduction + SSI + withholding trio eases cash up front.
If none fits fully? For a software developer providing independent remote services abroad without being a group affiliate, there is an adjacent regime: the CITL art.10/1-(ğ) foreign-service deduction rose to 100% with the Presidential Decision of 30/4/2026, with no location or headcount requirement. If you do export manufacturing, the free zone (3218) is a separate calculation.

The trap: many firms plan “I’ll take all three and use whichever is most advantageous.” The law does not permit this.

The Double-Benefit Ban and Pillar Two

No two regimes on the same income. Law No. 5746 art.4/5 is explicit: “Those benefiting from the deductions, exemptions, support and incentives under this Law … cannot separately benefit from provisions of the same nature in other laws.” In concrete terms: for the same project you cannot benefit from both the Technopark (4691) income exemption and the 5746 R&D deduction at the same time. The same employee, in the same month, cannot benefit from both the technopark withholding exemption and the R&D centre withholding incentive — you must choose one. On the QSC side there is a similar limit: an employee operating in the Istanbul Finance Centre and benefiting from the IFC wage exemption cannot also receive the PITL art.23/1-(20) QSC wage exemption (Law 7582 art.12, Law No. 7412 art.6/2). You must separate the cost centres cleanly.

In a large group the value of the exemption erodes. Corporate Income Tax Law Additional art.6 governs the global minimum top-up tax and its rate is clear: “The minimum corporate tax rate is 15%.” This concerns only multinational groups with consolidated annual revenue exceeding 750 million euros. If the Turkish affiliate of such a group pulls its effective tax rate below 15% through the Technopark/QSC exemption, the difference is collected domestically as a top-up tax (QDMTT) — the exemption is economically neutralized. Two refinements save the job: first, the substance-based income exclusion computed over personnel and tangible assets narrows the top-up tax base; in a personnel-heavy game studio this is a serious buffer. Second, because income-tax withholding and SSI reductions are not counted as “covered taxes” and are not penalized, the QSC wage exemption and the 5746 SSI/withholding support are Pillar Two-resilient — what actually erodes is the CIT exemption on profit.

A relief for local scale: the domestic minimum corporate tax (CITL art.32/C) cannot be less than 10% of pre-deduction income, but the legislator has expressly placed the 4691 income exemption, the R&D/design deduction and the CITL 10/1-(j) QSC deduction among the items deducted from the base in this 10% calculation. So for a software/game firm below the 750-million-euro threshold, all three incentives apply at full strength, uncut by the 10% minimum tax.

Gökay GÜL’s Note: The mistake I most often see in the field is firms choosing among these three regimes by “whichever has the lowest tax rate.” Yet what usually decides is loss-carryforward flexibility and personnel cost, not the rate on paper. Before recommending a technopark to a newly founded studio that won’t turn a profit for two or three years, ask this: if it makes a loss this year, where will it use that loss? In the technopark it burns; at the R&D Centre it accumulates. Before deciding, put the firm’s 3-year cash-flow projection on the table; the rate table alone misleads.

Field Case: The Studio That Moved From Technopark to R&D Centre

We worked with the Turkey studio of a Scandinavian game group at the end of 2025. At founding their natural choice had been a technopark: small team, office in the zone, income exemption. But within two years the picture changed. The team grew from 12 to 17, the company made losses two years in a row because of a long-cycle production, and part of those losses were related to out-of-zone revenue items (publishing commission, consultancy).

The problem was this: under the technopark exemption, they could not deduct the loss arising from zone activity against their other income — the loss was burning. Their headcount had also reached the level to meet the R&D Centre threshold. The calculation we ran showed two gains in moving to the R&D Centre model: first, the accumulated R&D deduction could be carried, indexed with revaluation, into a profitable year; second, half of the SSI employer premium and the withholding remission brought the monthly cash relief that the technopark did not provide in a personnel-heavy structure. The zone office’s rent/service cost also fell away.

The transition decision was made. The critical point was that, because of Law 5746 art.4/5, the two regimes could not overlap on the same income; so we made the transition at the accounting-period boundary, with a clean cut. The result: even though the effective tax burden looked higher on paper than the technopark in the first year, once the accumulated deduction and the personnel support were factored in, the three-year total cash position improved markedly.

Frequently Asked Questions

1. Should a game firm enter a technopark or an R&D Centre? If you are profitable and can sit in a physical zone, Technopark is simpler and lower-taxed. If you are a studio not yet profitable, personnel-heavy, developing a long project, the R&D Centre’s deduction-carryforward and SSI/withholding support are more valuable. The decision is a matter of cash flow and loss flexibility, not the rate.

2. How many staff are needed for an R&D Centre (2026)? The general threshold in the statute is at least 50 full-time-equivalent R&D staff; the President may reduce this number to 15 on a sectoral basis (Law 5746 art.4/6). For a design centre the threshold is at least 10 full-time-equivalent design staff. In the technopark there is no minimum headcount.

3. Who is the Qualified Service Centre (QSC) advantageous for? For capital companies that are part of a group operating in at least 3 different countries and derive at least 80% of their annual revenue from related companies abroad. 95% of the foreign income (100% in the IFC / an eligible industrial zone) is deducted over 20 accounting periods. Local studios selling to independent customers do not fall within this definition.

4. Can Technopark and R&D Centre incentives be taken at the same time? Not for the same income. Law 5746 art.4/5 bans a taxpayer benefiting from R&D incentives from also benefiting from the 4691 Technopark exemption and the CITL 10/1-(ğ) / PITL art.89/1-(13) provisions on the same income. Separate regimes can be structured for distinct, separated income and cost centres — but this is an advanced structuring and must be done under advisor supervision.

5. Do Pillar Two / the global 15% minimum cancel these incentives? For local and mid-sized firms, no; Pillar Two covers only multinational groups above 750 million euros. Below the threshold the three incentives run fully and are also protected from the domestic 10% minimum corporate tax (CITL art.32/C). In a group above the threshold the income exemption may be trimmed; the payroll (wage/SSI) incentives remain resilient.

Action List

Identify your profile (this week): Clarify the source of your income (domestic/foreign, independent/group), your headcount and whether you can enter a physical office. Your first “yes” on the decision tree gives you your regime.
Produce a 3-year cash-flow projection: the exemption-or-deduction decision depends on profitability timing. If there are loss years ahead, model the R&D Centre’s carryforward advantage.
Factor in the fund obligation: 3% at the technopark (5M TL threshold / 100M cap), 2% at the R&D Centre (1M threshold / 20M cap) — these are separate mechanisms; budget the amount to be locked in equity.
If the group is above 750M euros, have the Pillar Two analysis done up front: compute how much the income exemption will be neutralized by QDMTT, the SBIE buffer, and the resilience of the payroll incentives.
If you are considering a QSC, follow the regulation: until the Ministry of Industry and Technology implementation regulation is published, status determination and the scope of qualified/support staff will not be settled; following the communiqué/regulation before the decision is mandatory.
