Do you want to start an online shop, work as a freelancer or launch a side hustle? Then you might be asking yourself: when do I have to register a business? For many people this is hard to judge at first, because not every self-employed activity automatically counts as a trade (Gewerbe).
Getting the timing right matters. Register too late and you risk fines, tax problems or questions from the tax office. In this article you’ll learn when an activity counts as a trade, which exceptions exist and what to keep in mind with a small business or a side business.
What is a trade (Gewerbe)?
Whether your activity counts as a trade often has a bigger impact than many people realise at the start. It doesn’t just determine whether you have to register with the trade office (Gewerbeamt). Topics such as taxes, invoices, trade tax (Gewerbesteuer) or obligations towards the authorities come into play later, too.
What are the features of a trade?
A trade is a self-employed activity that is carried out on a lasting basis and with which you want to earn money. At the same time, you have to appear publicly with your services or products, for example through an online shop, social media or your own website.
Self-employed means that you work on your own account and at your own responsibility. An activity is considered lasting when it is carried out regularly and not just offered once. That’s why even small or part-time earnings can already count as a commercial activity.
The intention to make a profit is also decisive. As soon as you plan to generate income in the long term, registering a business may become necessary.
Which activities count as a trade?
Typical trades include a retail shop, a café, a craft business or an online shop. Many services count as a trade as well. These include, for example, cleaning services, photography or marketing services.
Many digital business models also fall under this category. Anyone who regularly sells products, builds websites or offers paid services is often already running a trade.
What does not count as a trade?
Not every form of self-employment automatically counts as a trade. In many cases, freelancers (Freiberufler:innen) do not have to register a business. These include, for example, doctors, lawyers, tax advisors and journalists, as well as many academic, artistic or creative professions.
However, the distinction isn’t always clear-cut. What matters is the specific activity. In some cases, freelance and commercial activities come together. The commercial part may then require a business registration.
So-called primary production is also treated differently from a legal point of view. This includes, for example, agriculture and forestry. The same applies to pure asset management, such as long-term share investments or renting out property.
Especially at the beginning, the distinction is often not clear. That’s why it’s worth checking early how your activity is classified. This helps you avoid later problems with the authorities or the tax office.
Who has to register a business?
As soon as you carry out a commercial activity on a self-employed, regular basis and with the intention of making a profit, a business registration is usually required. Who has to register a business therefore depends above all on the type of activity. It makes no difference whether you start full-time, on the side, or build a company together with others.
Which legal forms have to register a business?
Business registration applies to most classic company forms. These include sole proprietorships, small businesses (Kleingewerbe), civil-law partnerships (GbR), general partnerships (OHG) and corporations such as the UG or GmbH.
The registration particularly often affects sole traders. This applies, for example, to people with an online shop, services or craft activities. Small side businesses are often subject to registration as well, as soon as the activity is carried out regularly.
In partnerships such as the GbR, usually all managing partners have to be named. Corporations register the business through their legal representatives.
Does business registration also apply to a side business?
Part-time activities can already make a business registration necessary, too. Many people start with a side hustle or build up an additional income alongside their main job. What matters is not the working hours, but whether your activity meets the criteria of a trade.
This applies, for example, to selling via Etsy, Vinted or classified ads, but also to coaching, social media services or smaller digital services.
Who is exempt from business registration?
Not every self-employed activity needs a business registration. Freelancers are usually exempt. These include, among others, doctors, lawyers, tax advisors and journalists, as well as many academic and creative professions.
Agriculture and forestry normally don’t count as a trade either. The same applies to pure asset management, such as renting out property or private capital investments.
Important, though: even without a business registration there are often tax obligations. Freelancers still have to report their activity to the tax office and pay tax on their income correctly.
When do you have to register a business?
Many people think a business registration only becomes necessary above a certain turnover or profit. What really matters, however, is when your activity legally counts as commercial. In many cases the obligation to register therefore begins earlier than expected.
The exact timing of the registration
As soon as you actively offer your activity to the outside world, a business registration can become necessary. This is often the case when you sell products, offer services, advertise or win your first customers.
When does a business have to be registered? In principle, as early as possible before you start or right at the beginning of the activity. Wait too long and you risk problems with the authorities or the tax office. A retroactive registration is sometimes possible, but it doesn’t automatically protect you from fines or follow-up questions.
When for a small business or side business?
Especially with small projects or side hustles, the uncertainty is often high. Many people ask themselves: when do you have to register a business if the activity only runs on the side or brings in little money at first?
It makes no difference whether you start full-time or part-time. What matters more is whether you offer services regularly and want to generate income in the long term. This can quickly be the case with Etsy shops, social media services, coaching or digital services.
Students, employees or self-employed people with an additional side income therefore also have to check whether their activity already counts as a trade.
From what turnover / profit do you have to register a business?
There is no fixed turnover threshold for business registration. When you have to register a business therefore doesn’t depend directly on how much money you earn.
Turnover and profit thresholds mainly play a role for tax topics, such as the small-business regulation (Kleinunternehmerregelung) or trade tax. For the small-business regulation, the current limits are €25,000 in the previous year and €100,000 in the current year. The obligation to register a business, however, can exist even before that.
That’s why it makes sense to classify your own activity correctly as early as possible. This helps you avoid later problems with taxes, invoices or the authorities.
Distinction: freelance activity, small business, side business
The terms freelancer, small-business owner (Kleinunternehmer:in) and side business are often confused. Behind them, however, are different legal and tax rules. That’s why it’s important to know the differences early on.
Freelancers: do they have to register a business?
Freelancers usually don’t need a business registration. These include, among others, doctors, lawyers, journalists or many creative and academic professions. What matters is the specific activity. Many still ask: when do I have to register a business? With digital professions in particular, the distinction can be difficult. Even without a trade licence (Gewerbeschein), freelancers have to report their activity to the tax office and pay tax on their income.
Small-business owner vs. small business vs. side business
Kleinunternehmer:in describes a tax regulation for VAT. Kleingewerbe, on the other hand, means a small commercial business. Nebengewerbe (side business) only means that the activity is carried out part-time. A designer, for example, can be both a small-business owner for VAT and the operator of a side business at the same time. When a business registration becomes necessary therefore doesn’t depend on the term, but on the actual activity.
Legal basics and consequences of a late registration
Business registration in Germany is regulated by law. Anyone who starts a commercial activity generally has to report it to the responsible trade office. Depending on the industry, additional rules may apply.
Legal basis of business registration
The legal basis for business registration is set out in the Trade Regulation Act (Gewerbeordnung). It stipulates that traders have to notify the responsible authority of their activity. Additional requirements apply to certain industries. These include, for example, licence-requiring activities such as gastronomy, security services, financial brokerage or certain crafts. Here, permits, proofs of competence or further documents may be required.
What happens if you register your business too late or not at all?
Anyone who registers a business late or not at all risks fines from the trade office. The tax office can also claim back taxes retroactively and charge late-payment surcharges or interest. Many people therefore wonder when they actually need a trade licence. Above all, it’s important to classify the activity correctly early on. Anyone who works permanently without registration takes not only tax-related, but also legal and business risks.
Step by step: how to register a business correctly
In many cities, business registration is now straightforward. Nevertheless, the process, responsibilities and requirements differ slightly depending on the industry, legal form and place of residence.
Where do you register a business?
The responsible office is usually the local trade office, the public order office (Ordnungsamt) or the city administration at the place of business. In larger cities there are often several district or citizens’ offices. Many municipalities now also offer business registration online. Which office is responsible depends on where your company is registered. On the cities’ websites you’ll usually find digital forms, appointment booking and information about the process.
Which documents do you need for business registration?
For the registration you usually need an identity card or passport, your address details and a description of the planned activity. When you have to register a business depends on the activity, but the documents are often similar. For corporations, additional documents such as a commercial register extract or articles of association are required. For certain industries, permits, proofs of competence or entries in the register of craftsmen (Handwerksrolle) may also be necessary.
The registration process (including online)
Business registration usually starts with filling in a form. There you state, among other things, the legal form, company name and activity. You then submit the documents and pay the fee. On site, you often receive the trade licence directly or a few days later. Online, processing can take a little longer. The exact process depends on the respective city or municipality.
Cost of business registration
The costs differ depending on the city and federal state. The fees for business registration are often between €20 and €60. When a business has to be registered is regulated by law; the level of the fees, however, is not standardised. Additional costs can arise, for example, from commercial register entries, notary fees, permits or special licences.
What happens after business registration?
With the business registration, the bureaucratic part isn’t yet completely done. After registration, the most important information is automatically forwarded to other authorities and institutions. These include, among others, the tax office, the Chamber of Industry and Commerce (IHK), the Chamber of Crafts and, depending on the activity, also professional associations or other bodies.
At first, many people only ask: do I have to register a business? But further important steps follow afterwards. As a rule, the tax office gets in touch shortly afterwards with the tax registration questionnaire. There you state, among other things, whether you want to use the small-business regulation and how your turnover is likely to look.
Which tasks come up for founders afterwards?
After registration, you should take care of bookkeeping, invoices and separating your private and business finances early on. With side businesses in particular, this is often underestimated at first. The question of whether VAT applies, or whether the small-business regulation makes sense, can also become important.
Health insurance also plays a role when your self-employment grows or is carried out full-time. Employees, students or self-employed people with several sources of income should therefore check early what effect the activity can have on insurance or contributions.
In addition, many founders receive letters from the IHK or the Chamber of Crafts. Depending on the industry, mandatory membership can arise there. Some activities also require registration with a professional association. So plan the next steps after business registration right from the start.

Special features in certain situations
Depending on your life situation or business model, additional rules can apply to business registration. So check early which special features are relevant to your situation.
Side business in different life situations
Employees are generally allowed to register a side business. Nevertheless, the employment contract, working time law or non-compete clauses can play a role. In many cases the employer has to be informed about the secondary activity.
Special rules also apply to students, pupils or unemployed people. Additional income or working hours can have an impact on BAföG (student aid), child benefit, health insurance or social benefits. That’s why you should check before you start which limits and obligations apply.
Relocation and changes
If your address, place of business or activity changes, the business often has to be re-registered. This also applies to changes to the company name, the legal form or the field of activity.
A business deregistration is necessary when the activity is permanently ended. Longer interruptions can be relevant, too. Depending on the change, the authorities require additional documents or new information. So report changes to the responsible trade office as early as possible.
Special types of trade
Besides classic trades, there are also special forms such as the itinerant trade (Reisegewerbe). Here goods or services are offered without a fixed location, for example at markets or directly at the customer’s.
Certain activities are additionally subject to a licence. These include, among others, gastronomy, security services or some trading and brokerage activities. Many crafts also require an entry in the register of craftsmen. Only after that – or at the same time – can the business registration take place.
From when do you have to pay trade tax (Gewerbesteuer)?
Many people confuse business registration with trade tax. In fact, these are two different topics. The obligation to register a business usually arises right at the beginning of a commercial activity. Trade tax, on the other hand, often only applies later, once certain profit thresholds are exceeded.
When does trade tax become due?
For sole proprietorships and partnerships, a tax-free allowance of €24,500 applies. Trade tax only becomes due once the annual trade income is above that. Smaller side businesses or new companies therefore often pay no trade tax at first.
Corporations such as the GmbH or UG, on the other hand, don’t have this allowance. There, trade tax can in principle become relevant from the first euro of profit.
Business registration and trade tax are not the same thing
Important: the obligation to register a business doesn’t depend on whether you already have to pay trade tax. Many people think they only have to register a business above a certain turnover or profit. More important than turnover or profit, however, is the type of activity.
How is trade tax connected to other taxes?
Trade tax is added on top of income tax or corporation tax. Sole traders and partnerships can have part of the trade tax they’ve paid credited against their income tax.
How high the actual burden is also depends on the assessment rate (Hebesatz) of the respective municipality. As a result, trade tax can vary in amount depending on the location.
Checklist: from when do you have to register a business?
Whether an activity already counts as a trade can’t always be recognised straight away. Especially with small projects, digital services or side income, the uncertainty is often high. These questions help you to classify your situation better. Do one or more of these points apply to you?
The more questions you answer with “yes”, the more likely a business registration is required. It’s best to document early what your activity looks like, what income is planned and how regularly you work.
This information also helps later in conversations with the trade office, the tax office or a tax advisor. Especially with digital business models or side businesses, it’s worth classifying your own activity correctly as early as possible.
