The QSC Income-Tax Break for Qualified Personnel

What the personnel break does

The Qualified Service Centre (QSC) regime is best known for its corporate deduction, but it carries a second, quieter benefit that lands on the payroll. For qualified service personnel, the part of salary up to three times the gross minimum wage is exempt from income tax. The exemption attaches to the individual's pay, so the effect is felt directly in the cost of employing the people who actually run the centre.

The mechanic is a ceiling, not an all-or-nothing switch. Salary within the band — anything up to three times the gross minimum wage — comes out of the income-tax net; anything above that ceiling is taxed under the ordinary rules. So a senior hire whose pay sits well above the threshold still enjoys the exemption on the sheltered portion, with normal taxation only on the excess.

Because the exemption is expressed as a multiple of the gross minimum wage rather than a fixed lira figure, the sheltered band moves with the statutory minimum wage over time instead of being frozen at a nominal amount.

Who counts as qualified service personnel

The break is not a general payroll subsidy — it is targeted at the people delivering the centre's qualifying work. In substance, that means the staff engaged in the qualifying service functions the regime is built around: the coordination, management, treasury and support roles that a QSC provides to related group entities abroad. These are the regional-headquarters people — the group finance and treasury team, the regional managers, the coordination and shared-service staff.

Getting the population right matters, because eligibility for the QSC itself depends on the company meeting the four cumulative conditions — capital-company form, three-country reach, the 80% foreign-affiliate revenue threshold, and activity within the qualifying categories. If you are still testing whether the centre qualifies at all, start with do you qualify as a Qualified Service Centre; the personnel break only comes into play once the centre is inside the regime.

Why it lowers the cost of placing senior staff

Relocating senior people is expensive, and income tax on their salaries is a large part of that cost. By lifting income tax off the salary band up to three times the gross minimum wage, the QSC break reduces the real, after-tax cost of stationing experienced coordination, treasury and management staff in Türkiye. For the same net pay in an employee's pocket, the employer's gross cost is lower — or, put the other way, the same budget buys more senior talent.

How it sits alongside the corporate deduction

The personnel exemption and the corporate deduction are separate levers that pull in the same direction. At the company level, the centre deducts 95% of qualifying foreign-source service income — 100% inside the Istanbul Financial Centre or an approved zone, as explained in 95% vs 100% and the IFC uplift. At the payroll level, the qualified staff enjoy the income-tax exemption on the sheltered salary band. Together they lower both the group's Turkish corporate tax on the qualifying income and the cost of employing the people who generate it, which is exactly what a regional-headquarters incentive is meant to do.
