Working Student & Internship Tax Calculator Germany 2026

Most working students pay little to no income tax in Germany. With the 2026 tax-free allowance (Grundfreibetrag) of €12,348 per year, you only start paying income tax once your annual earnings exceed approximately €13,614 (after deducting the €1,230 Werbungskostenpauschale and €36 Sonderausgabenpauschale). For social security, working students benefit from the Werkstudentenprivileg and only pay pension insurance at 9.3% of gross salary.

The Werkstudentenprivileg (working student privilege) is a German social security exemption for enrolled university students working up to 20 hours per week during the lecture period. It exempts you from health insurance, unemployment insurance, and nursing care insurance contributions. You only pay pension insurance (9.3% of your gross salary). During semester breaks, you can work full-time and still keep this privilege.

If you only have one employer and are in Tax Class I, you generally don't need to file a tax return. However, filing voluntarily is often beneficial — you may get a refund if your employer withheld more tax than necessary, especially if you didn't work the full year or had expenses like commuting costs. You can file for the previous 4 years retroactively.

In 2026, the mini-job threshold (geringfügige Beschäftigung) is €603 per month. If your earnings stay at or below this amount, your employer pays a flat-rate tax of 2%, and you receive your full gross salary with no deductions for taxes or social security contributions. This is tied to the minimum wage (currently €13.90/hour).

Yes. Compulsory internships (Pflichtpraktikum) required by your university curriculum are completely exempt from social security contributions, regardless of how much you earn or how many hours you work. Voluntary internships follow standard employment rules — if you're enrolled as a student, the Werkstudentenprivileg may apply (only pension insurance). Income tax is calculated the same way for both.

During lecture periods, you can work a maximum of 20 hours per week to maintain your Werkstudentenprivileg. During semester breaks (vorlesungsfreie Zeit), you can work full-time without losing the privilege. If you consistently exceed 20 hours during lectures, you may lose the working student status and become subject to full social security contributions — significantly increasing your deductions.
