Why this matters
Students often start with little capital but a lot of flexibility. At the same time, BAföG, health insurance, family insurance coverage, working hours, and registration all depend heavily on your individual situation. Clarifying these things early prevents uncomfortable follow-up questions later.
Turn knowledge into a start plan
This guide explains one topic. Whether it is really a priority for you right now depends on your answers in the start plan.
Create start planThe most important distinction: testing an idea vs. working self-employed on a regular basis
A university project, a one-off test, or a small favour for friends is something different from an ongoing offer with prices, customers, a platform, a shop, or invoices.
As soon as you regularly offer services or sell goods, you should check whether registration with the Gewerbeamt (trade office) or the Finanzamt (tax office) becomes necessary.
Talk to your health insurance early — about family coverage too
Students must have health insurance. Your income and the number of hours you work can affect whether family insurance (Familienversicherung), student health insurance (studentische Krankenversicherung), or a different classification applies to you.
The Deutsches Studierendenwerk (German National Association for Student Affairs) points out that multiple activities can be assessed together in terms of hours worked. That is why you should realistically estimate not just your revenue but also your weekly hours — and ask your health insurer before relying on assumptions.
Do not guess at how BAföG and income interact
BAföG (Bundesausbildungsförderungsgesetz — Germany's student financial aid) depends on several factors. Your own income and assets can be taken into account, but the exact calculation varies from case to case.
Use official information or contact your Amt für Ausbildungsförderung (student aid office) if you receive or want to apply for BAföG. A side business can make practical sense, but you should understand the funding rules and documentation requirements beforehand.
Time is your scarcest start-up resource
A side business alongside your studies competes with lectures, exams, a part-time job, rest, and everyday living costs. So plan not just for revenue, but for a repeatable weekly routine.
For many students, a small, clearly defined offer works better than a shop that permanently demands support, shipping, returns, and content creation.
A simple setup is often enough
Start with a clear description of your activity, registration and tax registration, a folder for receipts, a simple invoice template, and clear payment methods. Only after that does it make sense to choose tools.
If you sell goods, packaging, an Impressum (legally required site notice), and platform data come into play. If you offer services, the focus is more on a description of your services, contracts, invoicing, and liability.
Quick checklist
- Describe your activity in one sentence.
- Note down as a key question: commercial (gewerblich) or freelance (freiberuflich)?
- Contact your health insurer before starting any regular activity.
- Check the impact on BAföG through official channels or your student aid office, if relevant.
- Plan your weekly hours realistically and factor in exam periods.
- Prepare your registration, tax questionnaire (Steuerfragebogen), and receipts.
- If selling goods, check LUCID (packaging register), Impressum requirements, and platform data obligations.
Common mistakes
- Focusing only on revenue and forgetting about hours worked.
- Only informing your health insurer once income is already coming in regularly.
- Estimating the impact on BAföG based on forum posts instead of checking officially.
- Not accounting for exam periods and busy study phases when planning your offer.
- Buying expensive tools too early, before you have a repeatable offer in place.
Frequently asked questions
Can I register a side business as a student?
In principle, this can be possible. What matters is your specific activity, registration requirements, insurance situation, BAföG, hours worked, and your individual circumstances.
Do I need to inform my health insurer?
If you are regularly earning income from self-employed work, you should contact your health insurer early. The number of hours you work and your income can both be relevant for how you are classified.
What is the best way for students to get started?
A small, clearly defined offer with clean documentation is often better than a complex shop or tool stack. The starter guide helps you find the right order of steps.
