Frequently asked questions

Does the staff cap (10%) apply to voluntary internships only?
Yes. The 10% cap applies specifically to voluntary internships.
What counts as disguised employment?
A voluntary internship that extends beyond 6 months, lacks a learning component, or places the intern in a regular production role.
Can a voluntary internship exceed 6 months?
No. Beyond 6 months the arrangement is at significant risk of being requalified by the ITM as disguised employment.
When do social contributions start applying to a voluntary internship?
As soon as the allowance crosses 40% of the SSM. At that point, the intern is treated as an employee for social security purposes.
