Side hustle without a permit - Fines, Central Trade and Industry Register and criminal liability - Criminally overemployed in Germany Part 4

Upwork jobs on weekends, an Etsy shop, or a YouTube channel with advertising revenue: Many skilled workers in Germany build a side hustle as a second source of income, register a business, and consider the matter settled. But from a residency perspective, it isn't.

When do I need a permit?

Whenever the conditions (Nebenbestimmung) in your residence permit, usually on the supplementary sheet (Zusatzblatt), do not already allow self-employment.

If it says “Erwerbstätigkeit gestattet” (gainful employment permitted), you may engage in any gainful employment, including self-employment. Self-employment is also allowed if it says “Selbstständige Tätigkeit gestattet” or “Selbstständige Tätigkeit erlaubt” (self-employment permitted). In Berlin, you may then found a company, run a business or work as a freelancer without any further application. This is how the Berlin Immigration Office (Landesamt für Einwanderung, LEA) describes it (as of March 10, 2026).

We have explained the basics of § 21 Abs. 6 AufenthG (German Residence Act), including the requirements and application process, for self-employment with the Blue Card and for residence permits for self-employment, including the so-called freelance visa. Regarding freelance remote work, we have explained when a permit is required.

According to § 2 Abs. 2 AufenthG, gainful employment (Erwerbstätigkeit) means self-employment, employment as defined in § 7 SGB IV (Social Code Book IV), and work as a civil servant. According to established case law of the Federal Social Court (BSG), self-employment differs from employment, based on an overall assessment, primarily through the individual's own entrepreneurial risk, their own business premises, the ability to dispose of their own labor, and the essentially unrestricted organization of their work and working hours. If you work via Upwork and are effectively subject to instructions from a single client, this may constitute employment – in which case the rules for a second job apply.

This question usually does not arise for Etsy shops or YouTube channels. Anyone who generates income on a permanent basis and with the intention of making a profit – advertising revenue, sponsorships, shop sales – is generally considered self-employed.

I hardly earn anything from it!

There is no de minimis threshold. How much you earn only affects the amount of the fine (§ 17 Abs. 3 OWiG, Administrative Offences Act).

Any self-employed activity requires a permit, as the term “gainful employment” in § 2 Abs. 2 AufenthG has no lower quantitative limit. The only exceptions are activities without the intention of making a profit, such as a pure hobby like a YouTube channel without monetization.

So do I need to register a business for that?

Yes, if it is a business in the legal sense (Gewerbe).

According to established case law of the Federal Administrative Court (BVerwG), this is the case if it is “a self-employed activity that is not socially unacceptable (generally not prohibited), aimed at generating profit, and intended to be permanent, and which does not belong to primary production, the liberal professions (freie Berufe), or the mere management of one's own assets” (BVerwG, decision of March 11, 2008 – 6 B 2.08).

According to this, an Etsy shop is considered a business, and a monetized YouTube channel usually is as well in practice. For Upwork assignments, it depends on the type of work: translating, designing, or programming can be considered liberal professions. In that case, business registration is not required – but you still need a permit from the immigration authority (Ausländerbehörde). A business must be registered according to § 14 Abs. 1 S. 1 GewO (Trade Regulation Act) – in Berlin, this can be done online at the trade office (Gewerbeamt). Important: Business registration (Gewerbeanmeldung) does not replace the permit under residence law, and vice versa.

What happens if you haven't done everything perfectly, as required by German law?

Double risk of fines

As we have explained for a second job with a Blue Card and for the Opportunity Card, it is an administrative offense to intentionally or negligently engage in self-employment contrary to § 4a Abs. 3 S. 4 AufenthG (§ 98 Abs. 3 Nr. 1, Abs. 5 AufenthG). Intentional violations can result in a fine of up to €5,000, while negligence can result in a maximum fine of €2,500 (§ 17 Abs. 2 OWiG). German Customs (Zoll) is responsible for enforcement (§ 71a Abs. 1 S. 1 AufenthG). Since December 24, 2025, self-employment with the Opportunity Card (Chancenkarte) for job search has also been subject to a fine (§ 98 Abs. 3 Nr. 1 in conjunction with § 20a Abs. 2 AufenthG).

If you have not registered a business, a fine of up to €1,000 may be added (§ 146 Abs. 2 Nr. 2 lit. b, Abs. 3 GewO). This fine is not imposed by Customs, but by the authority responsible under state law. Not registering in order to stay under the radar therefore does not help.

Could I end up in the Central Trade and Industry Register?

Yes, if the fine is legally binding and exceeds €200.

Up to this point, self-employment as a side hustle hardly differs from a second job without a permit – with one small difference: the entry in the Central Trade and Industry Register (Gewerbezentralregister). This register is kept by the Federal Office of Justice (Bundesamt für Justiz) (§ 149 Abs. 1 GewO). You can think of it as a kind of certificate of good conduct for entrepreneurs. Among other things, it records all legally binding fines exceeding €200 for an offense committed in or in connection with the operation of a business or of another commercial enterprise (§ 149 Abs. 2 S. 1 Nr. 3 GewO).

In the case of a business without a permit and without registration, two fines are therefore conceivable: one for the missing permit (§ 98 Abs. 3 Nr. 1 AufenthG) and one for the missing registration (§ 146 Abs. 2 Nr. 2 lit. b GewO). If each exceeds €200, each can also lead to an entry in the Central Trade and Industry Register. For the fine under the Residence Act, this applies because the offense is likely to be connected with the operation of the business.

When does it become a crime?

If you conceal your side job in your application to the immigration authorities or provide false information there, or if you persistently repeat violations. A fine and a register entry alone, on the other hand, are not a criminal record and do not in themselves lead to deportation.

In practice, two scenarios are particularly relevant:

Firstly, there is the temptation to omit information about small-scale self-employment when, for example, applying for an extension of your residence permit. Deliberately providing false or incomplete information to obtain a residence permit is a criminal offense under § 95 Abs. 2 Nr. 2 AufenthG (imprisonment of up to three years or a fine) and gives rise to an interest in expulsion (Ausweisungsinteresse) under § 54 Abs. 2 Nr. 8 lit. a AufenthG. This does not automatically lead to expulsion. However, it can jeopardize the extension, because a residence permit is generally only granted if there is no interest in expulsion (§ 5 Abs. 1 Nr. 2 AufenthG).

Secondly, fine notices (Bußgeldbescheide) are often not taken seriously enough. If the offense continues unabated, this can be considered intentional, persistent repetition, potentially leading to prosecution under § 11 Abs. 1 Nr. 2 lit. d SchwarzArbG (Act on Combating Undeclared Work), with imprisonment of up to one year or a fine.

If such a conviction involves a sentence exceeding 90 daily rates (Tagessätze) or more than three months' imprisonment, it is also entered in the Central Trade and Industry Register (§ 149 Abs. 2 S. 1 Nr. 4 GewO). The threshold of 90 daily rates also plays a role when you apply for German citizenship (Einbürgerung) (§ 12a StAG, Nationality Act).

Conclusion: Break the chain as early as possible

As you can see, these kinds of cases don't start with a serious offense, but with seemingly trivial matters and minor fines. The danger isn't the individual fine, but the spiral it can trigger. This also increases the risk of getting caught. Ideally, of course, you'd plan your side hustle so thoroughly that there's no risk from the outset. But in reality, hobbies tend to gradually evolve into side hustles that become larger and more lucrative. Mistakes happen in dynamic situations – that's normal. A fine notice is a clear warning sign that you should not ignore, but actively take into account in your planning.

What matters is the order: first the permit from the immigration authority, then starting your side hustle and registering your business at the same time. If you are already working without a permit, pause the activity and apply for the permit before you submit your next extension application. You can only file an objection (Einspruch) against a fine notice within two weeks of service (§ 67 Abs. 1 OWiG). If you receive a hearing questionnaire (Anhörungsbogen), seek legal advice before making any statement.

Quick answer

• A self-employed side hustle on an EU Blue Card or another German residence permit, such as an Etsy shop, a YouTube channel with ad revenue or freelancing on Upwork, is only allowed if the conditions on your supplementary sheet (Zusatzblatt) permit it, for example with “Erwerbstätigkeit gestattet” (gainful employment permitted). Otherwise, you first need a permit from the immigration authority (Ausländerbehörde) (§ 21 Abs. 6 AufenthG).

• There is no minimum income threshold. Only a hobby without the intention of making a profit is exempt (§ 2 Abs. 2 AufenthG).

• Registering a business (Gewerbeanmeldung) does not replace the permit. If you run a business, you need both (§ 14 Abs. 1 S. 1 GewO).

• Without a permit, German Customs (Zoll) can impose a fine of up to €5,000 (§ 98 Abs. 3 Nr. 1 AufenthG). Failing to register a business can add up to €1,000 (§ 146 Abs. 2 Nr. 2 lit. b GewO). Fines over €200 can be entered in the Central Trade and Industry Register (Gewerbezentralregister) (§ 149 Abs. 2 S. 1 Nr. 3 GewO).

fr

• A fine is not a criminal record and does not in itself lead to deportation. It becomes a criminal offense if you conceal your side job or give false information in your application to the immigration authority (§ 95 Abs. 2 Nr. 2 AufenthG), or if you intentionally and persistently repeat violations (§ 11 Abs. 1 Nr. 2 lit. d SchwarzArbG).
