Note: This article is for general information and does not replace individual legal advice. The requirements for a residence permit under § 21 of the Residence Act (AufenthG) are complex and are handled differently by immigration authorities. Please seek advice before submitting an application.

A convincing business plan, secure financing, and a business idea that benefits the German economy. These are the three keys that open the door to self-employment in Germany for non-EU citizens.

Sounds feasible? It is. But the details are what count. Which business ideas will convince the immigration authorities, why a corner snack bar has to meet different requirements than an IT consulting firm, and why freelancers have it significantly easier than tradespeople: all of this is regulated by § 21 of the Residence Act (AufenthG). And that's exactly what this article is about.

We explain the different paths to self-employment, the prerequisites, the application procedure, the required documents, and the path from a temporary residence permit to a settlement permit and then to Naturalisation.

The five routes under Section 21 of the Residence Act

• Section 21 of the Residence Act (AufenthG) does not describe a single set of circumstances, but rather summarises five different routes to self-employment. Which one is right for you depends on your qualifications, your business idea, and your current residency status.

Paragraph	For whom?	Core requirement	Fixed-term
Abs. 1	Businesses (e.g. trade, catering, crafts, IT services)	Economic interest, positive economic impact, secured financing	Max. 3 years
Abs. 2	Nationals of certain contracting states (e.g. USA, Turkey, Japan)	Reciprocity in international law	Max. 3 years
Section 2a	Graduates from German universities, researchers, scientists, Blue Card holders	Connection with studies/research. Facilitated prerequisites.	Max. 3 years
Section 2b	Skilled workers with start-up grants	Scholarship from a German organisation, living expenses covered	Maximum 18 months
Absolute 5	Self-employed professionals (e.g. doctors, architects, artists, interpreters, IT consultants)	Positive economic or cultural impact. Work permit.	Varied (often 1–3 years)

 

In addition, there is Section 21 Paragraph 6 of the Residence Act: Anyone who already possesses a residence permit for another purpose (e.g. study, family reunification, skilled worker) can obtain a permit to pursue self-employment. additionally received without having to meet the prerequisites of paragraph 1. The decision rests with the immigration authority. You can find an overview of the different purposes of residence in our article about residence purposes of the Residence Act.

Trade or profession: Why the distinction is crucial

In German law, there is a fundamental distinction between commercial and freelance activities. This difference has direct implications for your residence permit.

Commercial activity (§ 21 Para 1)

Anyone operating a trade or business (commerce, gastronomy, crafts, IT services through a GmbH or as a sole proprietor) must fulfil all the requirements of § 21 (1): economic interest, positive economic effects, and secured financing. The Chamber of Industry and Commerce or the Chamber of Crafts will be involved and issue a statement. The assessment standard is high.

Important: Businesses that cater exclusively to end consumers (e.g. a corner shop, a hair salon) do not automatically meet the criteria. Here, a specific regional need must be demonstrated. An IT company that creates jobs and operates with an export focus has significantly better prospects.

Example: A software developer from India with five years of professional experience, €40,000 in equity, and two signed Letters of Intent from German companies is applying for a residence permit for an IT consultancy as a sole proprietorship. The Chamber of Industry and Commerce (IHK) positively assesses the business plan: clear market niche, comprehensible earnings forecast, two secured initial contracts. The Foreigners' Authority grants the residence permit for three years. For comparison: an applicant without industry experience, without equity, and with a three-page business plan for a delivery service will have a considerably harder time.

Self-employment (§ 21 (5))

For freelancers, simplified conditions apply. The strict criteria of paragraph 1 (economic interest, Chamber of Commerce and Industry opinion) do not need to be met. It is sufficient that positive economic or cultural effects are expected from the activity and that the required professional permit is available or has been promised.

Self-employed activities as defined by Section 18 (1) of the German Income Tax Act (EStG) include, among others: doctors, dentists, lawyers, engineers, architects, auditors, tax advisors, interpreters, translators, artists, writers, and journalists. Software developers and IT consultants working independently can also be considered freelancers under certain conditions.

Warning: The English term „freelancer“ is not identical to the German „Freiberufler“. Whether your activity is classified as self-employed for tax and trade law purposes must be examined on a case-by-case basis. An incorrect classification can lead to your application being rejected.

Business registration and special permits

Regardless of your residence permit, you must meet the usual trade law requirements for commercial activities. This includes registering your business with the relevant trade office. For certain activities, you will require additional permits: a restaurant permit for the catering industry, registration in the craft register for trades requiring a licence (with a master craftsman's certificate or equivalent qualification), or a broker's permit (§ 34c GewO) for real estate agency.

Before submitting your application, clarify whether your planned activity requires a special permit. If this is missing, the immigration authority can reject the application for this reason alone.

Special route for university graduates and researchers (§ 21 para. 2a)

If you have successfully completed your studies at a German university of applied sciences or hold a residence permit for researchers or scientists under §§ 18b, 18d, 19c (1) of the Residence Act (AufenthG) or an EU Blue Card, shall You are to be granted a residence permit for self-employment. The word „shall“ means: the authority must grant it if the requirements are met. It is no longer a discretionary decision.

The prerequisite is that your planned self-employment must have a clear connection to your studies or your research activities. A computer science graduate founding a software company meets this. A computer science graduate opening a restaurant generally does not.

This route is particularly attractive because the strict assessment criteria of paragraph 1 (economic interest, Chamber of Industry and Commerce participation, proof of funding) do not apply. Proof of a connection to one's studies is sufficient.

The three requirements for tradespeople (§ 21(1))

For the residence permit for self-employment, three requirements must be met simultaneously:

1. Economic interest or regional need

The Immigration Office will assess whether your business idea holds a superior economic interest. The evaluation will be based on the viability of the business idea, your entrepreneurial experience, the amount of capital invested, the impact on employment and training, and the contribution to innovation and research.

A company that creates jobs, is innovative, or fills a gap in the regional market has a good chance. Another takeaway on a street with ten existing takeaways does not.

2. Positive effects on the economy

This checks whether your company can make a measurable economic contribution: turnover, jobs, tax revenue, innovation potential. The responsible Chamber of Industry and Commerce or Chamber of Crafts provides an expert opinion. This opinion is not binding, but the immigration authority usually follows it.

Projects that create skilled jobs, are located in a growing sector (e.g. IT, renewable energy, the health sector), or are export-oriented have particularly good prospects. Business models based solely on the local consumer market (retail, gastronomy) must demonstrate a specific regional need, for example, through municipal development plans or needs analyses by public bodies.

3. Secured Financing

You must demonstrate that the financing for your project is secured by equity or a commitment of credit. A business plan including an earnings forecast, investment plan, and liquidity plan is essential. The immigration authorities do not expect millions, but a realistic and comprehensible financial plan.

The Business Plan: What the Authority Wants to See

The business plan is the central document of your application. The Stuttgart Chamber of Commerce and Industry (IHK) recommends 25 to 40 pages. It should answer the following questions:

• Business idea: What exactly do you want to do in Germany? What problem does your company solve? Who are your customers?
• Market analysis What does the market look like? Who are your competitors? What makes you different?
• Qualification What entrepreneurial experience do you have? What industry knowledge? What degrees or certificates?
• Financial plan Capital requirements plan, investment plan, sales and earnings forecast for at least three years, liquidity plan.
• Jobs: Are you planning to hire staff? How many, and when?
• Location Why Germany? Why this location?

The business plan should be professionally prepared. If you are unsure, have it reviewed by a business consultant or tax advisor. A poorly prepared business plan is the most common reason for an application to be rejected.

What differentiates a good business plan from a bad one: The Chamber of Commerce regularly sees business plans that consist only of general statements („I want to start a successful business“) or whose revenue forecasts are clearly made up. A convincing plan, on the other hand, shows that you know your market, can estimate your costs realistically, and have a concrete strategy for the first three years. Industry-specific key figures, specifically named potential customers or clients, and a comprehensible break-even point make the difference.

Important: The business plan must be submitted in German or with a certified translation.

General requirements (§ 5 AufenthG)

In addition to the special requirements of Section 21, you must also meet the general requirements for granting a visa as set out in Section 5(1) of the Residence Act:

• Secure livelihood: You must be able to provide for yourself and your family without relying on state benefits.
• Health insurance Statutory health insurance or equivalent private health insurance in Germany. Foreign health insurance is not sufficient. Self-employed individuals are usually privately insured; expect monthly costs of 300 to 700 Euros, depending on age and tariff. This is a significant item in your financial planning.
• Identity and Passport Obligation: Valid passport. Identity must be established.
• No grounds for deportation No prior convictions, no ongoing investigation. Even fines can prevent a licence being granted.
• German language skills: There is no formal language requirement for a residence permit under § 21. However, the business plan must be submitted in German (or with a certified translation), and communication with the Chamber of Industry and Commerce (IHK) and authorities takes place in German. For a settlement permit after three years, B1-level proficiency is required.
• Retirement Planning (from age 45): From 01/07/2025, applicants over 45 years of age must prove that they will have a minimum monthly pension of €1,612.53 (for at least 12 years) or assets of at least €232,204 upon reaching the age of 67.

The application procedure step by step

Entry and visa

Fundamentally, you must have the residence permit before entry at the competent German mission abroad (embassy or consulate-general) in your home country. A Schengen visa A short-stay (C-visa) is not sufficient.

Exception: Nationals of certain countries may enter visa-free and submit their application to the local immigration authority. These include, among others, Australia, Japan, Canada, New Zealand, the United Kingdom, and the USA. However, even with visa-free entry, the following applies: work may only commence once the residence permit has been granted.

Application to the Foreigners' Authority

After entering the country (or if you are already in Germany with another residence permit), you submit the application to the foreigner's registration office in your place of residence. In many cities, applications can now be submitted online (e.g. Berlin, Frankfurt).

Involvement of specialist agencies and IHK opinion

The Foreigners' Registration Office involves the relevant Chamber of Industry and Commerce (IHK) or Chamber of Crafts, the trade regulatory authority, and, if applicable, other bodies. The IHK will review your business plan based on the legal criteria and provide an expert opinion. This step can take several weeks.

The statement is not binding, but it carries considerable weight. A negative Chamber of Industry and Commerce (IHK) statement almost always leads to the rejection of the application. Conversely, a positive statement provides a strong basis for approval.

The Chamber of Industry and Commerce pays particular attention to three things: Is the financial plan realistic and comprehensible? Does the founder have sufficient experience for the planned undertaking? And does the company create a recognizable added value for the regional economy? Submit the documents completely. Supplementary requests will delay the process by weeks.

Processing time

Expect a total of three to six months, depending on the immigration office and the complexity of the case. In large cities like Berlin, Munich or Frankfurt, it may take longer. Factor this waiting period into your company formation. If your current residence permit expires during the process, you will usually receive a Fictitious certificate, which secures your stay until the decision.

Tip: Make your application for an extension no earlier than four months before your current residence permit expires. This will prevent a gap in your residence status.

Extension of residence permit

When extending after two or three years, the authorities will check whether your self-employment is economically viable. The key evidence is the Audit report by a tax advisor, which confirms your income, business development, and livelihood. This report must be stamped with an official seal.

Additionally, the following are required: the latest income tax assessment, a net profit calculation, bank statements for the last six months, and proof of health insurance. Freelancers do not need to submit a formal audit report, but must prove their secure livelihood.

The crucial point is: your company doesn't need to be large. It needs to cover your living expenses. A small consultancy firm with a stable income will have a better chance of renewal than an ambitious start-up that is still making losses after two years.

Required documents

The exact list varies depending on the foreigners' registration office, but the following documents are regularly required:

• Valid passport
• Biometric passport photo
• Existing residence permit (if applicable)
• Business plan with financial plan (income forecast, investment plan, liquidity plan)
• Proof of financing (bank statements, loan commitment, proof of equity)
• Business registration or extract from the commercial register (if already available)
• Proof of qualifications (degrees, certificates, professional experience)
• Proof of health insurance in Germany
• Lease agreement for residential and commercial premises
• Proof of retirement provision (for applicants over 45 years of age)
• Upon renewal: Tax advisor's report on income and business development

From residence permit to settlement permit

The residence permit under § 21 is limited to a maximum of three years. After that, a particularly attractive option opens up:

After only three years Can self-employed individuals with a residence permit under § 21(1) apply for a settlement permit (§ 21(4) AufenthG)? This is faster than the usual route via § 9 AufenthG, which requires five years.

Requirements for the settlement permit after three years:

• You have been successfully self-employed for three years.
• The activity suggests further sustainable business development.
• Your livelihood and that of your family is secure.
• Sufficient knowledge of the German language and basic knowledge of the legal and social order (§ 9 para. 2 sentence 1 no. 4 of the Residence Act).

Warning: This shortened process does not apply to freelancers. Freelancers can only apply for a settlement permit under the regular conditions of § 9 AufenthG, which is usually after five years. More on this in our article on Settlement permit for skilled workers.

And after that: Naturalisation

With a settlement permit and secure livelihood, the path to German citizenship is open to you. Since the new Citizenship Act (In force since June 2024) naturalisation is possible after five years of lawful residence, and even after three years in cases of special integration achievements (e.g. C1 language certificate, voluntary work). Dual nationality has generally been permitted since 2024.

In concrete terms, this means: residence permit under Section 21, settlement permit after three years, naturalisation after a further two years. In favourable cases, you can transition from a visa to German citizenship within five years. You can find detailed information in our article on new citizenship law.

Family reunification for self-employed individuals

If you hold a residence permit according to § 21, your spouse and minor children can join you in Germany within the scope of family reunification (§§ 29–32 of the Residence Act).

Prerequisites for spouse reunification: adequate living space, secure livelihood (also for the spouse, without claiming social benefits) and, as a rule, basic German language skills (A1) of the joining spouse. Easier conditions apply for children reunification; children under 16 years of age have a general right to reunification.

Important for planning: Family reunification is only possible once your residence permit has been issued and you can demonstrate that the livelihood of the entire family is secured. The higher cost of living for a family will be taken into account in the calculation. Please include this in your business plan.

Typical problems and grounds for refusal

Not every application is successful. The most common reasons for rejection:

• Business plan not convincing Unrealistic sales forecasts, missing financial plan, no discernible market advantage.
• No positive economic effects demonstrable: Particularly for businesses that exclusively target end consumers, without creating jobs.
• Funding not secured Insufficient equity, no loan approval, unclear source of funds.
• Subsistence not secured The authority must assume that you and your family can live without social benefits.
• Incorrect classification of the activity Application submitted as a freelancer when the activity is commercial, or vice versa.
• Pure equity participation Mere participation in a company without actual entrepreneurial activity is not sufficient.
• Suspicion of bogus self-employment: If the authorities get the impression that you are factually working for only one client and are bound by instructions, there is no genuine self-employment. This can lead to both the rejection of the application and consequences under social security law.

If your application is rejected, you have the option to lodge an appeal or bring an action before the administrative court. In both cases, deadlines apply. Have a rejection reviewed by a lawyer promptly.

GmbH, UG or sole proprietorship?

Many founders wonder which legal form is suitable for the application according to § 21 AufenthG. The decisive factor is not the legal form, but whether you are actually engaged in entrepreneurial activity.

As a managing director of a GmbH or UG (limited liability), you can obtain a residence permit under § 21 if you are actually in a managerial role and have been appointed to the management by the company's articles of association. A mere capital investment without operational activity is not sufficient.

The application is also possible for sole traders or partners in a partnership (GbR, OHG, KG), as long as you yourself bear the entrepreneurial responsibility.

A common mistake: Founders who set up a limited liability company (GmbH) with a German business partner as the majority shareholder, while holding only a minority stake themselves and not being a managing director. In this scenario, from the authorities' perspective, there is no self-employed activity. Those who merely contribute capital as silent partners also do not meet the requirements.

There is no prescribed legal form. A UG (limited liability), GmbH, and sole proprietorship are all equally permissible. It is crucial that you can demonstrably exercise entrepreneurial management.

Frequently asked questions about the residence permit according to § 21 of the Residence Act

As an EU citizen, do I need a residence permit to be self-employed?

No. EU citizens and nationals of Iceland, Norway, Liechtenstein, and Switzerland enjoy freedom of establishment. They can set up a business in Germany without a residence permit.

How much capital do I need?

There is no statutory minimum amount. The previous requirement of an investment sum of €250,000 and five jobs was abolished in 2012. The crucial factor is that the financing of your specific project is demonstrably secured.

Can I convert my existing residence permit into a residence permit under Section 21?

Yes, that is fundamentally possible. Anyone who already holds a residence permit for another purpose can apply for a change of purpose at the immigration authority. For holders of a residence permit under §§ 18a, 18b (skilled workers) or an EU Blue Card, there are simplified conditions.

May I work while my application is being processed?

This depends on your current residence permit. A residence permit under § 21 only authorises self-employment specifically named in the permit. Do not commence any activity before the permit has been issued. A violation can have criminal consequences and jeopardise future applications.

What happens if my business fails?

If your livelihood is no longer secured, the immigration authorities may refuse to extend your residence permit. You can then try to switch to a different purpose of stay (e.g. skilled worker, if you meet the requirements). Taking up dependent employment may also be an option, provided that your residence permit allows for it.

Which international law agreements facilitate access?

Germany has agreements with the following states that allow for facilitated conditions for self-employment (§ 21 (2) of the Residence Act): Dominican Republic, Indonesia, Iran, Japan, Philippines, Sri Lanka, Turkey and USA. The exact scope of these benefits depends on the specific agreement and will be examined by the authorities on a case-by-case basis.

How much does the residence permit cost?

The fees are currently €100 for the initial application and €93 for the renewal. In addition, there are costs for the creation of the business plan (a professional plan costs between €1,000 and €5,000, depending on complexity), certifications, translations, and, if applicable, legal advice.

Can I change my business activities?

All changes to your self-employed activity must be reported promptly to the immigration office. A change of industry or a fundamental change to the business model may trigger a new review. Speak to your lawyer before making any significant changes.

Can I work as an employee alongside my self-employment?

The residence permit under Section 21 generally only authorises self-employment in the activity stated in the permit. Secondary employment as an employee must be approved separately by the immigration authority.

We advise you on your start-up in Germany

The residence permit according to § 21 AufenthG offers non-EU citizens one of the most attractive routes to Germany: self-employment, a settlement permit after three years, and naturalisation after five. However, the application is complex, and the immigration authorities have considerable discretionary powers.

What you will receive from us: An assessment of whether your project meets the requirements of § 21 and whether the self-employed or freelance route is the right one for you. Support with the application process and communication with the immigration authorities. And if necessary: Representation in objection or legal proceedings in the event of refusal.
