What this is really about
Your legal structure is the legal framework within which your venture operates. It affects who acts, who is liable, how complex your bookkeeping and administrative requirements become, how ownership stakes work, and how your business appears to the outside world.
For a side business in Germany, the goal is not to start with unnecessary complexity. It is about understanding which structure broadly fits your plans and knowing at which points you should involve official bodies, the IHK (Chamber of Commerce and Industry), a tax advisor, or legal counsel.
Important: 'freelance' (freiberuflich) is not a legal structure like UG or GmbH. It is first and foremost a classification of your activity. This question often comes before the choice of legal structure, because it can affect registration, the trade office (Gewerbeamt), and the tax office (Finanzamt).
Before the legal structure: freelance or trade-based activity?
Freelance professions (freie Berufe) cover certain self-employed activities, for example in fields that are catalogue-listed, advisory, artistic, scientific, teaching-related, or similar. Freelancers typically register their activity with the tax office (Finanzamt) rather than through a standard trade registration (Gewerbeanmeldung) at the trade office (Gewerbeamt).
Trade-based activities (gewerbliche Tätigkeiten) are typical for retail, online shops, brokerage, production, many local services, platform-based models, or whenever goods are sold. In these cases, trade registration, possible chamber membership, and trade tax (Gewerbesteuer) topics come into play.
The boundary is not always intuitive. A designer, developer, coach, or content offering can be classified differently depending on the specific service provided. For a binding tax classification, what ultimately matters is not the headline on your website, but the actual activity you carry out.
Einzelunternehmen (sole proprietorship): often the simplest solo start
If you are starting alone and do not want to form a company, the Einzelunternehmen (sole proprietorship) is the most straightforward framework for many small trade-based or freelance starts. It is comparatively simple, easy to understand, and often a good fit when you are testing an idea on the side.
The trade-off for this simplicity is the close connection between you and your business. Business risks can affect your personal assets. That is why liability, contracts, insurance, and the nature of your offering should not be ignored just because the structure seems simple.
For typical side projects such as small services, creative work, digital products, or first online shops, the Einzelunternehmen is often the starting point — but it is not automatically the best fit for risky products, larger contracts, or team setups.
GbR: when at least two people start together
The Gesellschaft bürgerlichen Rechts, or GbR (civil law partnership), is a simple partnership for at least two people pursuing a shared goal. It can become relevant for small teams, collaborations, or joint freelance projects.
Precisely because the GbR seems simple, it is often underestimated. Those involved should clarify in writing who contributes what, who has decision-making authority, how profits and costs are divided, what happens when someone leaves, and who is responsible towards clients or partners.
The key learning question for your starting path is: Am I truly starting together with others, or would a loose collaboration or contractor relationship be cleaner than forming a joint company?
e.K., OHG, and KG: more specialised than a typical side business start
The eingetragener Kaufmann or eingetragene Kauffrau (e.K.) — a registered sole merchant — applies to sole traders with an entry in the commercial register (Handelsregister). This is not the same as a small unregistered sole proprietorship and brings greater external credibility, but also more formal obligations.
The OHG (Offene Handelsgesellschaft, or general commercial partnership) is a partnership for a commercial business with multiple people. It is more formal than a simple GbR and better suited to commercially oriented ventures, not a quick small-scale test alongside a main job.
The KG (Kommanditgesellschaft, or limited partnership) separates roles more clearly: at least one person manages and bears greater liability, while others participate mainly with capital and a limited liability amount. This can make sense in certain situations, but for a typical small side business it is generally not a starting point without professional guidance.
UG and GmbH: limited liability with more structure
The UG (haftungsbeschränkt) — a mini limited liability company — and the GmbH (Gesellschaft mit beschränkter Haftung, or limited liability company) are both corporations (Kapitalgesellschaften). They are independent legal entities. This can structure liability, external appearance, ownership stakes, team building, or larger contracts differently than a sole proprietorship or GbR.
However, these structures come with significantly more administrative requirements: a notary, commercial register entry, articles of association, stricter bookkeeping, annual financial statements, and ongoing administration. A limited liability company is therefore not automatically the smart default for every small side business.
The UG can seem appealing as a smaller option when limiting liability becomes important but a GmbH still feels too large. Even so, the capital must realistically match the activity. A GmbH appears more professional and stable, but also carries more weight. Neither should be chosen purely for prestige.
How to approach the decision as a learning process
A helpful sequence is: classify your activity, clarify whether you are starting solo or with others, assess your liability risk, understand the bookkeeping and administrative burden, consider how you need to appear externally — and only then choose the appropriate structure.
For many side businesses in Germany, the first real choice comes down to a sole proprietorship (Einzelunternehmen), freelance activity as an individual, or a GbR if multiple people are involved. A UG or GmbH becomes more relevant when risk, growth, ownership stakes, larger contracts, or a professional external image justify it.

Questions that may matter for your case
These questions help you classify the topic. In the start plan they are connected to your situation. You can also think through the answers beforehand.
- Does your activity sound more like a freelance professional service or a trade-based business?
- Are you starting alone or together with other people?
- Are there relevant liability risks arising from advice, products, client projects, premises, equipment, or larger contracts?
- Is a simple start more important to you, or do you specifically need a limited liability company structure?
- How much bookkeeping, incorporation, and administrative effort is realistically manageable for your side business?
- Do you need a particular external image towards clients, banks, suppliers, or partners?
