Technopark Payroll Incentives Are Their Own Regime, With Their Own Paperwork (2026)

Say “technopark” and people think of the corporate tax exemption first. Yet in most companies the side of a technopark that touches cash flow is payroll. The corporate tax advantage only helps once you are profitable; the payroll incentives reduce employer cost from the very first month.

I put the distinction to early-stage companies like this: the earnings exemption affects the tax on your profit, the payroll incentive affects the cost of your salaries. In a software company not yet making a profit, the second is far more concrete than the first.

There are two separate incentives, and they get conflated

The income tax withholding exemption. An exemption applies to the income tax computed on the wages of personnel working in R&D, software and design activities in the zone, in respect of those duties. This reduces the employer’s total cost without changing the employee’s net salary — or allows a higher net payment within the same budget. Which of those you choose is your own compensation policy.

The employer’s social security premium support. A portion of the employer’s social security share for in-scope personnel is met from the budget. It is a mechanism independent of the income tax side, and the two apply together.

These have to be tracked separately, because their scope and documentation requirements are not identical.

Support staff: the 10% and 20% rule

This is the limit most often missed. The number of support personnel who can benefit from the incentives cannot exceed 10% of the number of R&D and design personnel. In zone companies with total headcount up to 15, that ratio is applied as 20%.

What that means in practice: in a company with a 20-person R&D team, the number of support staff who can benefit is capped at 2. HR, accounting, administration, office management — all of these are support personnel, and any excess above the cap falls outside the incentive.

The 20% allowed for smaller companies is a deliberate flexibility: in a ten-person team it would be disproportionate for the single administrative employee to fall outside.

The critical point here is getting the classification right at the outset — who counts as “R&D personnel” and who as “support personnel”. The classification is made by reference to the work done on the project, not by job title on the payroll.

Personnel working outside the zone

Remote work is the part of the payroll incentives that attracts the most questions. The current rules allow work outside the zone at 100% for IT personnel and 75% for other project personnel, and that authorisation runs to 31 December 2026.

Because these ratios affect both the incentives and the exemption, and because the date is approaching, I have dealt with the topic separately: remote work in a Turkish technopark.

Documentation: the real condition

The legal basis for the incentives is solid, but in practice their survival depends on documents. Three things are asked for in an audit:

Notification to the zone management company. That the employee works in the zone, which project they are on and their status must be reported regularly. Where the notification discipline is poor, the incentive becomes contestable. A gap between headcount in the notifications and headcount on the payroll is one of the first things questioned.

The project file. Evidence that the project the employee works on is in scope. Project definition, outputs, progress records.

Time records. In particular, if an employee works on both in-scope and out-of-scope work, the portion of the wage subject to the exemption must rest on an allocation. Saying “it’s all R&D” does not remove the need for that allocation.

A company that builds these three has an advantage. A company that does not has an amount that may be reclaimed retrospectively.

Three common mistakes

One: A founder classifying themselves as R&D personnel while actually working on sales and management. This is the pattern spotted fastest in an audit.

Two: Not tracking the support staff ratio. As the team grows the administrative headcount grows with it and the 10% cap is quietly breached. It is noticed not in the month it happens but in the year it is examined.

Three: Not tracking the ratio for personnel working outside the zone. The permitted ratio is a ceiling; once exceeded, the incentive cannot be applied to the excess.

In short

The payroll advantage of a technopark arrives earlier than the corporate tax advantage and, in most early-stage companies, is larger. But it has three limits: the employee must actually work on an in-scope project in the zone, support personnel are capped at 10% (20% in small companies), and out-of-zone work is subject to the permitted ratio. All three rest on documentation.
