The question comes up in almost every initial conversation: should I register as a student employee or under a mini-job arrangement? The answer depends on just a few, but decisive, factors.
A mini-job allows a monthly income of up to 603 euros tax-free from 2026. There is no restriction on working hours - in theory you can work as many hours as you like, as long as the 603-euro threshold is not exceeded. The employer pays social security contributions on a flat-rate basis.
Mini-jobbers are exempt from social security contributions as long as monthly earnings do not exceed the mini-job threshold of 603 euros (§ 8 para. 1 SGB IV, as of 2026).
The mini-job is ideal for short, flexible assignments: trade fair jobs, event staffing, catering. No paperwork, no bureaucratic burden - the employer registers you with the mini-job centre.
As a student employee, you can earn significantly more than 603 euros per month. The so-called student employee privilege secures the favorable health insurance through your parents or the student tariff - under one central condition: a maximum of 20 hours per week during the lecture period.
For sporadic assignments (trade fairs, events, weekend cover), the mini-job is the simpler choice. Anyone who wants to earn regularly and more than 603 euros per month is much better off with student employee status. Many students combine both: a student employee job as a solid base, supplemented by mini-job assignments for larger trade fairs or events.
The mini-job threshold of 603 euros has been in effect since 1 January 2026 and is linked to the statutory minimum wage. At an hourly rate of 13.90 euros gross (minimum wage 2026), this works out arithmetically to around 43 hours of work per month. Earn even one euro more and you lose mini-job status - the job then becomes a social-security-liable midi-job.
For student employee positions, there is no income ceiling. What matters is solely the 20-hour limit during the lecture period. During semester breaks, the number of hours may be exceeded for up to 26 weeks per year. Anyone who plans carefully can achieve an annual income of 15,000 euros or more through holiday jobs and semester assignments without losing the student employee privilege.
The student employee privilege only applies if studies form the main focus of life. Weekly working hours during the lecture period must not exceed 20 hours on an annual average (§ 27 para. 4 SGB III).
Between the mini-job and student employment lies the midi-job: a social-security-liable employment relationship with a monthly income between 603.01 euros and 2,000 euros. Within this transitional range, the employee pays reduced social security contributions. For students, the midi-job is rarely the optimal model - it offers neither the simplicity of the mini-job nor the freedom of student employee status. Nevertheless, it can make sense when hours are too high for a mini-job but student employee status is not available.
This is the core point of the comparison: with a mini-job, the employer bears around 28 to 30 percent of gross wages in flat-rate contributions - for pension insurance, health insurance, and taxes. You as the employee pay nothing, but are only partially protected. Specifically: no statutory unemployment insurance, no independent health insurance membership through the job, no entitlement to sick pay after six weeks of continued pay.
As a student employee, however, you are liable to pay pension insurance - a small deduction from gross wages, but one that builds up pension credits. Health, nursing care, and unemployment insurance are waived under the student employee privilege. This makes student employee status more favorable overall than a regular social-security-liable employment relationship.
Student employees are exempt from health, nursing care, and unemployment insurance contributions, but pay the full pension insurance contribution of currently 18.6 percent (split equally between employer and employee). Legal basis: § 6 para. 1 no. 3 SGB V, § 27 para. 4 SGB III.
Students up to 25 years are usually covered free of charge under parental family insurance - both in a mini-job and in a student employee position. From age 25, or if personal income exceeds 565 euros per month (2026; or the mini-job threshold of 603 euros in the case of a pure mini-job), family insurance ends. The student health insurance then becomes relevant: it currently costs around 120 to 150 euros per month and remains in place until the age of 30 or the end of the 14th semester - regardless of whether you hold a mini-job or student employment. The income difference between the two models has no impact on this insurance status.
Not every position suits every employment status. In practice, there are clear patterns as to which sectors and job types work well with which model.
Particularly in the event industry, many employers deliberately use the mini-job for student jobs - because the administrative burden for individual assignments under mini-job status is lower. For positions with regular shifts and fixed planning, student employee status is significantly more attractive for both sides. Employers who regularly deploy students as student employees benefit from lower ancillary wage costs compared to regular part-time employment.
A widespread misconception: the mini-job is not automatically tax-free. It is exempt from wage tax if the employer assumes the flat-rate tax of 2 percent - which is standard practice at the mini-job centre. If you have multiple mini-jobs simultaneously and together exceed the 603-euro threshold, it becomes more complex and you are required to file a tax return.
For student employee positions, the normal wage tax deduction under tax class I (or adjusted) applies. As a student, you usually have a claim to a tax refund because your annual income is below the basic allowance of 12,348 euros (2026). A voluntary tax return almost always pays off - refunds of 300 to 700 euros are not uncommon for student employees. Tuition fees, specialist literature, and travel costs can be claimed as work-related expenses or special expenses.
Anyone who holds both a student employee position and mini-jobs in parallel must be careful: the working hours from all jobs are added together. If the combined total exceeds the 20-hour limit during the lecture period, you lose the student employee privilege - and become liable to social security contributions for all jobs. This is not a theoretical risk, but a real pitfall. Employers are obliged to ask about other jobs at the start of employment. False statements can lead to back payments.
Instead of long checklists, four concrete questions help to make the right choice:
At ucm.jobs, students are guided directly through the registration process - whether mini-job or student employee. On the student page, you will find all open positions filtered by model as well as information on next steps. Anyone who wants to start working quickly without fighting through bureaucracy: registration takes under five minutes.
