The 30-Hour Average Rule Explained (Aliens Act § 77)
Under Section 77 of the Finnish Aliens Act (Ulkomaalaislaki 301/2004), a student residence permit grants unrestricted right to engage in gainful employment if the average working hours do not exceed 30 hours per week across the calendar year.
- Term-time average: Calculated over the academic year, allowing flexible week-to-week variations as long as the 30h average is maintained.
- Summer & Winter Recess: During official school holiday periods when no teaching takes place, students may work full-time (up to 40h/week or more) without restriction.
- Internships & Practical Training: Mandatory degree practical training (harjoittelu) and thesis work are exempt from the 30-hour limitation.
Collective Agreement Protection for Student Workers
Student employees in Finland enjoy identical legal rights, minimum wage floors, and working condition protections as full-time Finnish employees. Employers are legally prohibited from paying below the applicable collective agreement (TES) rate simply because a worker is a student or foreign national.
Tax Cards and Verokortti for Students
All student income in Finland is subject to Finnish taxation. Before receiving your first paycheck, you must obtain a tax card (verokortti) from the Finnish Tax Administration (Verohallinto). If your estimated annual income is low, your withholding tax percentage may be 0% or very low.
