Minijob, Werkstudent, or HiWi? Choosing a Student Job and Understanding the Tax in Germany (2026)
Most international students in Germany work on the side — for living costs, for experience, and to practice German. But which type should you choose: a Minijob, a Werkstudent (working student) role, or a HiWi (student assistant) job? Each comes with very different limits on hours, tax, and social-insurance contributions.
This guide explains the three most common forms, with a comparison table and notes on the work-time limit written on your residence permit.
📋 The Three Job Types at a Glance
| Job type | What it is | Best when |
|---|---|---|
| Minijob | a "mini" job with a monthly earnings cap | you want flexible, low-admin work |
| Werkstudent | max 20 hrs/week during the lecture period | you want field-related, higher-paid work |
| HiWi | student assistant at the university | you like research/teaching, close to campus |
| General note | hours limited by your residence permit | always check the current rules |

🎯 The Work-Time Limit for Non-EU Students
Students from non-EU countries may only work a limited number of days per year. The old rule was 120 full days or 240 half-days; under the 2024 reform this was increased (commonly cited as 140 full / 280 half-days). The figure can change and depends on your permit.
> 💡 Important: Always read the exact condition (Nebenbestimmung) noted on your residence permit (Aufenthaltstitel) — that is the limit binding on you, and you should re-confirm the current thresholds/days.
One important exception: a HiWi job at your own university is usually not counted toward this 120/140-day limit — but still ask the Ausländerbehörde to be sure.
🔍 How Minijob, Werkstudent, and HiWi Differ
The three forms differ in hours, pay, tax, and social insurance:
| Criterion | Minijob | Werkstudent | HiWi |
|---|---|---|---|
| Cap / limit | ~€556/month (2025) | max 20 hrs/week (lecture period) | per university contract |
| Pay level | low–medium | usually higher | by university pay grade |
| Social insurance | flat-rate (employer pays most) | Werkstudentenprivileg (reduced) | usually like Werkstudent |
| Field-related | usually no | usually yes | yes (research/teaching) |
| Income tax | usually very little/none | refundable | refundable |
Your Steuer-ID (tax ID) is what you must give your employer in all three job types so they calculate tax correctly.
🧮 Rules on Hours, Tax & Social Contributions
| Aspect | Minijob | Werkstudent / HiWi |
|---|---|---|
| Earnings limit | monthly cap (~€556 in 2025, rises with minimum wage) | no hard cap, but a 20-hr/week limit |
| During semester breaks | monthly cap stays | may work more than 20 hrs/week (days per visa) |
| Pension (Rentenversicherung) | small contribution (exemption possible) | usually mandatory |
| Health/care/unemployment | employer pays a flat amount | exempt via the Werkstudentenprivileg |
| Year-end refund | rarely needed | filing a Steuererklärung is worth it |
Figures like the Minijob cap or the hours threshold change yearly — check the official source (minijob-zentrale.de, your university's page, the Ausländerbehörde) for the current limit.
💼 Which One Should You Choose?
- Choose a Minijob if you want flexible, low-commitment work and only a small, steady top-up each month — for example serving, retail, or warehouse work.
- Choose Werkstudent if you want higher pay, field-related work, and can commit up to 20 hrs/week during the lecture period. It also strengthens your CV later.
- Choose HiWi if you enjoy the academic environment and want to work close to professors on research/teaching — very useful if you're aiming at the path to staying on to work after graduation.
Whatever you choose, track your total days/hours so you never exceed the limit on your residence permit.
⚠️ Common Mistakes & Tips
- Exceeding the day/hour limit: a breach of your residence conditions — it can seriously affect renewing your visa.
- Confusing "month" with "year": the Minijob cap is monthly; the 120/140-day limit is annual.
- Not giving your Steuer-ID: the employer withholds tax at a higher rate (Steuerklasse VI).
- Skipping the tax refund: many Werkstudenten/HiWis get money back by filing a tax return.
- Not prioritizing your studies: too many hours can slow your progress and risk the Werkstudentenprivileg.
❓ Frequently Asked Questions
Can I have a Minijob and a Werkstudent job at the same time? Possibly, but the total of your hours/days must stay within your residence permit's limit, and combining them can change how social insurance is calculated. Check with your health insurer.
What is the Werkstudentenprivileg? A rule under which students working up to 20 hrs/week during the lecture period are exempt from most social-insurance contributions (except pension), so net pay is higher.
Does a HiWi job count toward the 120/140-day limit? Work at your own university is usually not counted, but rules can vary — confirm with the Ausländerbehörde and your International Office.
Do I pay tax on a Minijob? A Minijob is usually taxed at a low flat rate handled by the employer, so you see almost no deductions — but always check the current threshold.
