Forming a GmbH in Cologne: Procedure, Costs and Typical Mistakes

A GmbH only comes into existence upon its entry in the commercial register. Until then, five steps must be completed: articles of association, notarisation, capital contribution, commercial register application and – after registration – trade and tax registration. This guide shows how the incorporation process works in practice in Cologne, what it costs based on current fees, what role the standard protocol plays and at which points mistakes later prove to be expensive.

When the GmbH is the right choice

The GmbH is by far the most commonly chosen type of limited liability company in Germany. It generally limits liability to the company's assets and leaves sufficient scope in contract design to reflect almost any structure, ranging from a two-person venture to a family business.

The GmbH is typically worthwhile if one of the following scenarios applies:

• You want to protect your private assets. Once your contribution has been made in full, you as a shareholder are generally not personally liable for the company's liabilities. Separate liability risks exist, inter alia, prior to registration, in the case of personal collateral and—for managing directors—in the event of a breach of their own duties.
• You are planning with investors or a later sale. GmbH shares are transferable in notarial form, divisible and can be structured in various ways – for example, with voting agreements or preferential rights.
• You need a legal entity for your business operations. Banks, landlords and clients often treat a GmbH differently to a sole proprietorship; for certain business models, the limited company is practically a prerequisite.

Requirements for setting up a GmbH

Before the initial notary appointment, three points should be clarified: shareholders and shares, share capital and company name. The notary notarises what is presented to them – they do not negotiate.

Shareholders and shares

A GmbH can be founded by a single person alone or by several shareholders together; both natural and legal persons are eligible, including those with their registered office abroad. The point of contention is rarely the number, but rather the distribution of shares, the appointment of the management and the voting rights structure. These questions belong in the articles of association – not in a later supplementary document.

Share capital: cash contribution or non-cash contribution

The minimum share capital is €25,000 (Section 5 GmbHG). It can be provided in cash or as a non-cash contribution. Both methods differ significantly:

• Formation of a company Before registration in the Commercial Register, at least 25 % must have been paid up against each share and a total of at least €12,500 (Section 7(2) of the GmbHGThe rest remains owed and can later be claimed by the company – including by an insolvency practitioner.
• Formation with non-cash contributions Non-cash contributions must be made in full prior to registration. In addition, Section 5(4) of the GmbHG requires a non-cash formation report in which the value is transparently demonstrated. If the actual value falls short of the stated value, the liability for deficits under Section 9 of the GmbHG applies.

Company name and legal form suffix

According to Section 18 of the German Commercial Code (HGB), the company name must possess the capacity for identification and distinctiveness, and in accordance with Section 30 of the HGB, it must clearly differ from existing companies at the same location. The legal form suffix „GmbH“ or „Gesellschaft mit beschränkter Haftung“ is mandatory (Section 4 of the German Limited Liability Companies Act (GmbHG)). A non-binding preliminary check by the IHK Cologne is free of charge and avoids the situation where the register court rejects the entry due to a risk of confusion – the notarisation appointment would then be in vain.

Registered office and domestic business address

Two terms that are often confused: The constituent meeting (§ 4a GmbHG) is a German location specified in the articles of association – comparable to the legal „registered office of the company“. The domestic business address (Section 8 (4) GmbHG) is the specific address at which the company can actually be reached; it is registered separately with the commercial register and entered there. Both do not have to be identical, but they must be real and capable of receiving mail.

The process step by step

Step 1: Preparation and partnership agreement

According to Section 3 of the German Limited Liability Companies Act (GmbHG), the articles of association must contain at least the company name, registered office, business object, share capital, and the number and nominal amounts of the shares. In practice, a good agreement regulates considerably more: appointment and dismissal of management, reservation of consent, voting rights, non-compete clauses, rules for departure, severance formulas, and succession in the event of death. Those who clarify these points before the notarisation appointment will noticeably save time and costs in the event of a dispute.

Step 2: Notarisation

The articles of association must be notarised (§ 2 para. 1 GmbHG). The notary reads out the contract, clarifies any questions and notarises the signatures. The managing directors are frequently appointed and the commercial register application prepared during the same appointment.

Online notarisation. Since 1 August 2022, notarial attestation of the formation of a limited liability company (GmbH) via video conference has been permitted (§ 2 para. 3 GmbHG). The prerequisites are an approved video communication system of the Federal Chamber of Notaries and an electronic identity document. This option has since been significantly expanded – it now also covers multi-person formations, resolutions amending the articles of association, and, within the legal framework, certain formations with non-cash contributions.

Step 3: Deposit of share capital

Following the notarisation, the directors open a business account in the name of the company „i. G.“ (in the process of being formed). The shareholders pay their cash contributions into this account – at least 25 % per share and a total of at least €12,500. Upon registration in the Commercial Register insured the managing director pursuant to section 8 (2) of the GmbHG that the contributions are at the free disposal of the company. In practice, the notary's office often requires proof of a bank account prior to submission; the registry court may request additional documents in the event of justified doubts.

Step 4: Application for registration in the commercial register

The managing directors apply for registration of the company in the commercial register (§§ 7, 8 GmbHG). The application is made in notarially certified form and is submitted electronically to the local court by the notary’s office. Enclosed are, among other things, the notarised articles of association, the shareholder list and – in the case of formations involving contributions in kind – the report on the formation involving contributions in kind. The register court examines the application pursuant to § 9c GmbHG and registers the company. Upon registration, the GmbH comes into existence as a legal entity (§ 11 para. 1 GmbHG).

Step 5: Business registration and tax registration

The business registration is carried out with the City of Cologne – Public Order Office, Trade Licensing Department. For limited companies, Cologne offers its own procedure that already includes a registration before Commercial register entry permitted („Business registration of a limited company – not yet entered in the commercial register“The actual start of the commercial activity is decisive.

Parallel is the Questionnaire for tax registration purposes to be completed and electronically via ELSTER to be submitted to the tax office – within one month of commencing the activity (§ 138 para. 1b AO). It forms the basis for the allocation of the tax number and – if required – the VAT identification number. In accordance with § 14 para. 4 UStG, invoices showing VAT must state either the tax number or the VAT ID number.

Model protocol or bespoke articles of association?

For simple formations, Section 2 Subsection 1a of the GmbH Act provides for Model protocol before: a legally pre-drafted document that combines the articles of association, appointment of the managing director and shareholder list in a single instrument. Notary fees are noticeably lower as a result – partly because the otherwise applicable minimum business value pursuant to Section 105 of the German Court and Notary Costs Act (GNotKG) does not apply here.

The standard memorandum of association is exclusively open for incorporations with

• at most three shareholders,
• exclusively to a managing director and
• cash deposits only.

Individual arrangements (such as on consent requirements, non-compete clauses or succession) are not possible – for these, an individual partnership agreement must be notarised.

Rule of thumb: As soon as two or more shareholders are involved, it should be considered whether an individual contract justifies the later effort. In the case of a single-person GmbH with a standard structure, the standard protocol is frequently the more efficient choice.

How much does it cost to set up a GmbH?

The total costs depend on the share capital, the chosen type of contract (standard protocol or individual contract) and the advisory effort. For the three largest mandatory items – notary, commercial register and business registration – the amounts can be stated quite precisely today:

Note: The exact notary's fees depend on the scope of the deed, the number of implementation services and supplementary declarations. The appointed notary's office will provide you with specific amounts before the appointment. Since 1 June 2025, in accordance with the Costs Law Amendment Act 2025 (KostBRÄG 2025), value-based fees in the Federal Lawyers' Fees Act (RVG) have been around six per cent higher. The €190 and €250 caps for initial consumer consultations (§ 34 RVG) have remained unchanged.

How long does the incorporation take?

With careful preparation, two to four weeks pass from the initial consultation to the entry in the commercial register. Following complete registration and prompt payment of costs, processing time at the Cologne District Court is about one week in straightforward cases (as also stated by the Cologne Chamber of Commerce and Industry).

Experience shows that time bottlenecks arise in three places:

• Appointment with the notary. Free appointments – especially with individual contracts – are not always available at short notice.
• Account opening and deposit. Without proof of the capital contribution, the registration cannot be sensibly submitted; opening an account „i. G.“ (in formation) takes anywhere from a few days to several weeks, depending on the bank.
• foundation report. In the case of contributions in kind, the documentation of value can take additional time; in cases of doubt, the register court will request an expert opinion.

What documents you should prepare

For a prompt notary appointment, the following information and documents are helpful:

• Identity card or passport of all shareholders and managing directors
• Proposed company name (ideally with preliminary Chamber of Commerce and Industry check) and proposed registered office
• Corporate purpose – formulated as specifically as possible
• Amount of share capital and distribution of shares
• Details of the appointment and representation authority of the managing directors
• Drafting of the partnership agreement or selection of the model protocol
• For non-cash contributions: non-cash formation report and evidence of value
• For foreign shareholdings: current commercial register extract or proof of representation of the participating company, with an apostille or legalisation and certified translation where applicable
• Bank details for the business account „i. G.“ – ideally with account opening arranged in advance

Common mistakes when setting up a GmbH

1. Do not have the company name checked in advance

If the company is first objected to by the register court, registration is delayed – the notary appointment may have to be repeated. The preliminary review by the Cologne Chamber of Commerce and Industry costs nothing and takes a few days.

2. Standard template chosen, even though an individual contract was necessary

The standard incorporation protocol saves on notary fees, but makes any individual arrangement impossible. Disputes regarding voting rights, distributions or the departure of a shareholder are then decided exclusively in accordance with the law. Subsequent restructuring is generally more complex than an individual agreement would have been at the beginning.

3. Physical contribution underestimated

The formation report on non-cash contributions must reliably document the value. If the value is questioned by the court of registration or if the differential liability pursuant to section 9 of the German Limited Liability Companies Act (GmbHG) applies later, the shareholder is personally liable for the difference. For larger non-cash contributions, an external valuation report is practically indispensable.

4. Address without guaranteed delivery

The domestic business address (§ 8 para. 4 GmbHG) must be genuinely reachable. If service of documents is not possible there, the court orders public service pursuant to § 15a HGB – deadlines then run against the company without it realising. Virtual office addresses are permitted if mail is actually processed and forwarded; empty mailbox solutions are risky.

5. Omitted legal form suffix

Anyone who acts in legal transactions without using the suffix „GmbH“ (§ 4 GmbHG) – on letterheads, invoices, in the legal notice – may expose themselves to liability based on apparent legal status. Whether and to what extent personal liability arises depends on the individual case.

Tax registration delayed

The questionnaire for tax registration must be submitted actively via ELSTER, generally within one month of commencing the activity (§ 138 para. 1b of the German Fiscal Code - AO). Anyone who waits for the tax office to write usually misses this deadline.

7. Overlooked Transparency Register

The GmbH is required to notify the transparency register of its beneficial owners (§ 20 GwG). Breaches of reporting obligations can be penalised with fines – in cases of intent, quite easily reaching five-digit figures.

What follows after registration in the commercial register

With the registration, the company has come into legal existence. Ongoing operations entail their own obligations:

• Questionnaire for tax registration (ELSTER, Section 138 (1b) of the German Fiscal Code (AO)): Submit electronically within a month. After that, the tax office will issue the tax number and – if required – the VAT ID number.
• Transparency Register (Section 20 Money Laundering Act (GwG)): The beneficial owners must be registered without delay and kept up to date.
• Income tax and national insurance: As soon as the GmbH employs staff, the corresponding registrations are due. For employed managing directors, the obligation to pay social security contributions depends on the individual case – in particular on the level of shareholding and subjection to instructions. In cases of doubt, a status determination procedure with the German Pension Insurance is advisable.
• Requirement to keep accounting records: As a commercial company by virtue of its legal form (§ 6 HGB), the GmbH is fully subject to the obligation to keep proper books of account; a tax adviser should be involved at an early stage.
• Annual accounts and filing: To be prepared in accordance with §§ 242 et seq. of the German Commercial Code (HGB) and disclosed in the company register depending on size.
• Legal notice: The website is subject to the requirements of Section 5 of the DDG (formerly Section 5 of the TMG); the company name, legal form, register court, commercial register number and managing directors are mandatory details.

Formation of a GmbH with foreign shareholders

Foreign natural persons and legal entities can become shareholders of a German GmbH without special approval. The act of incorporation follows the same rules, but in practice it is made more difficult by three issues:

• Proof of representation authority of legal entities. If a foreign company is involved, the notary regularly requires a current commercial register excerpt and proof of representation, frequently with Apostille or consular legalisation, as well as a certified translation. For individuals, a valid passport or identity card is generally sufficient.
• Online notarisation. Section 2(3) of the GmbHG (German Limited Liability Companies Act) permits notarisation via video conference. For shareholders outside Germany, this can significantly simplify the appointment – the prerequisite is an electronic identity verification, which not every foreign identity document offers.
• Account opening. When there is foreign participation, German banks are often hesitant when opening a business account for a company i. G. (in formation). The banking issue should be resolved early on so that the capital contribution does not become a bottleneck.
