You probably know that Germany has a tax-free Minijob system for students, but you might not realize how much you can optimize it—when earning over €538 is fine, when it causes problems, and what other legal income paths exist. This article explains the rules clearly.
Minijob: Basic Rules
A Minijob (mini job) is a form of marginal employment. The core rules:
- Monthly income cap: €538 (as of 2024, adjusted annually with the minimum wage)
- For you as employee: no income tax, no social security contributions (you can opt into pension insurance)
- For your employer: pays about 30% surcharge (pension, health, accident insurance) from their own costs
- No legal maximum working hours, but €538 divided by the minimum wage (€12.82/hour) ≈ 42 hours per month
The main appeal for students: Minijob income is not counted for income tax and does not affect your student public health insurance (GKV) rate. As long as you stay under €538/month, your insurance status stays the same.
What Happens If You Earn Over €538?
If your monthly income consistently exceeds €538, the job becomes a regular employment relationship (Midijob or standard employment):
- You pay income tax (Lohnsteuer)
- You pay social security contributions (pension, health, unemployment, care insurance), but with a transitional zone (Midijob: €538–€2,000/month, with gradually increasing contribution rates)
- If your monthly income exceeds a certain threshold, you may lose your student public health insurance eligibility and must insure as an employee, which is much more expensive
Occasionally exceeding the limit by a small amount (e.g., extra hours during holidays) won't trigger immediate problems—your employer can handle it via annual summary reporting. But if you exceed it for three consecutive months, you should discuss adjustments with your employer.
Working Hour Limits for Students
As a student visa holder in Germany, besides the Minijob income cap, there's another rule:
- Non-EU students can work a maximum of 120 full days or 240 half days per year
- Exceeding this requires special permission from the Foreigners' Office (Ausländerbehörde)
- A Minijob does not exempt you from this rule—if you have two Minijobs, you must combine the hours
In most cases, a single Minijob of 10–12 hours per week (monthly income around €400–€500) is fully compliant, so you don't need to worry.
HiWi: Academic Assistant Jobs
HiWi (Wissenschaftliche Hilfskraft, research assistant) is a student job within the university, usually hired by professors or lecturers.
- Hourly wage: €12–€16 (depending on the university and task type), above minimum wage
- Tasks: literature review, lab assistance, data processing, tutoring (Tutorium)
- If your monthly salary is ≤€538, it can be treated as a Minijob (tax-free); anything above is taxed as normal wage
- Closer contact with your supervisor—great for future recommendation letters
Annual Income and Tax-Free Allowance
Germany's income tax allowance (2026) is approximately €11,784 per year. If your total annual income (excluding tax-free Minijob income) is below this, you effectively pay zero tax.
Strategy:
- If you have a HiWi job with taxable income, file a tax return via ELSTER at year-end—you can likely get a full refund
- Many students get back €300–€600 per year, money that is often overlooked
Multiple Jobs: How It Works
- You can have two Minijobs simultaneously, but total monthly income must not exceed €538
- You can have one Minijob + one regular job (HiWi or standard employment)—tax and social security are calculated separately
- Remember: total working hours from both jobs must stay within the 120 full-day annual limit
Where to Find Minijobs
- Your university's Studentenwerk website job board
- minijob-zentrale.de (Federal Minijob Center, with job search function)
- Indeed.de search for "Minijob" + "your city"
- Ask directly at supermarkets, cafés, and fast-food restaurants—many small businesses need help but don't post online
- eBay Kleinanzeigen for local tutoring, moving help, parcel delivery, etc.
Summary
A Minijob (≤€538/month) is the easiest way for students to earn extra income—tax-free, no impact on public health insurance, and flexible. HiWi jobs pay more and connect you with academia, ideal for STEM students. Combining both, plus year-end tax refunds, can legally add €400–€700 net per month, significantly easing your living costs without crossing legal lines.
