Registering a UG (haftungsbeschränkt) in Germany: The Mini-GmbH for Startups

Not every budding entrepreneur has €25,000 in spare capital for a classic GmbH at the outset. It's precisely for such cases that German law has, since 2008, offered the UG (haftungsbeschränkt) — a "mini-GmbH" that can be registered with symbolic capital starting at €1. The UG is not a separate legal form in its own right, but rather a variant of the GmbH with its own special rules set out in § 5a of the Limited Liability Companies Act (GmbHG). In this article, we look at how the UG differs from a classic GmbH, how to register one, and what obligations it places on founders.

1. What Is a UG (haftungsbeschränkt) under § 5a GmbHG?

The UG (haftungsbeschränkt), short for Unternehmergesellschaft (haftungsbeschränkt), was introduced by the 2008 GmbH-law reform (MoMiG) as a "starter version" of the GmbH — with a lower minimum capital requirement, but with full limited liability for shareholders from the moment of formation. Legally, the UG is not governed by a separate statute but by the same GmbHG: all the general rules on governing bodies, director liability, the commercial register, insolvency proceedings, and so on apply to it, subject to a handful of exceptions expressly set out in § 5a. The company name must include the full designation "Unternehmergesellschaft (haftungsbeschränkt)" or the abbreviation "UG (haftungsbeschränkt)" — using "UG" alone, without "(haftungsbeschränkt)," is prohibited by law (§ 5a(1) GmbHG), since the full designation alerts business partners to the company's status and its reduced capital.

2. UG vs. GmbH: Key Differences

The most common misconception about the UG is that it somehow provides only "partial" limited liability. That's not the case: from the moment of registration, UG shareholders are liable for the company's obligations exactly as GmbH shareholders are — solely with the company's assets. The real differences lie elsewhere:

• Share capital. A GmbH requires at least €25,000; a UG requires as little as €1 per shareholder.
• Type of contribution. A GmbH allows both cash and in-kind contributions (Sacheinlagen); a UG allows only cash contributions, and these must be paid in full before registration.
• Mandatory legal reserve. A UG must set aside part of its annual profit into a reserve (see below); a GmbH has no such obligation.
• How business partners perceive it. A GmbH is generally seen by banks and business partners as a more established, reliable form, whereas a UG is sometimes associated with an early-stage business.

3. Share Capital: From €1, and No In-Kind Contributions

Formally, § 5a(1) GmbHG allows a UG to be registered with capital of as little as €1 per shareholder share. In practice, almost no one forms a company with €1 in capital — such a company would have no working capital even for its first expenses, which tends to discourage business partners rather than reassure them. A sensible benchmark in practice is capital somewhere between €100 and a few thousand euros, depending on the nature of the business. The real restriction lies elsewhere: § 5a(2) sentence 2 GmbHG expressly prohibits in-kind contributions (Sacheinlagen) when forming a UG — you cannot contribute equipment, a stake in another company, or other property as your contribution, only cash. And unlike a GmbH, where paying in half the capital is sufficient at the time of registration, a UG requires the entire declared capital to be paid into the company's account in full — before the registration application is filed with the Handelsregister.

4. The Mandatory Legal Reserve (Ansparpflicht)

The trade-off for the UG's reduced starting capital is an obligation to set aside part of its profit in a statutory reserve. Under § 5a(3) GmbHG, a UG must transfer at least 25% of its annual net profit (Jahresüberschuss, after deducting any loss carried forward from the prior year) into a legal reserve (gesetzliche Rücklage) every year — and must keep doing so until the sum of the nominal capital and the accumulated reserve reaches €25,000, the minimum capital threshold for a classic GmbH.

5. The Registration Process: Musterprotokoll and Simplified Notarization

Forming a UG largely mirrors the process for a GmbH, but turns out noticeably cheaper thanks to the low capital requirement. For straightforward cases — up to three shareholders and one director — the same standardized-protocol principle applies as for a GmbH: the Musterprotokoll combines the articles of association, the appointment of the Geschäftsführer, and the shareholder list into a single document. Since notary fees under the Court and Notary Fees Act (GNotKG) are tied to the amount of share capital (Geschäftswert), a UG's minimal capital means notary costs for a Musterprotokoll come out close to the minimum fee tier. The remaining steps are the same as for a GmbH: notarization (including, in simple cases, online notarization via video call), opening a bank account and paying in the capital in full, the notary filing the application with the Handelsregister, registration with the Gewerbeamt, and tax registration with the Finanzamt. Because using a Musterprotokoll means no Sachgründungsbericht is needed (since in-kind contributions are prohibited), registering a UG is usually faster and cheaper than registering a GmbH with individual articles.

6. Pros and Cons of a UG for Startups and Small Businesses

Advantages. The minimal capital threshold makes the UG a convenient vehicle for testing a business idea, converting a freelancer's practice into a legal entity, or quickly launching a tech startup. Registration is generally simpler and cheaper than for a GmbH, and limited liability applies right from the start — in that respect, the UG is every bit the equal of a GmbH. The company can later convert into a classic GmbH without going through liquidation and re-formation.

Disadvantages. The mandatory 25% profit set-aside limits how much can be distributed to shareholders in the early years. The ban on in-kind contributions means you can't, for example, contribute existing equipment, intellectual property, or an operating sole proprietorship when forming the company. The Musterprotokoll doesn't allow for individual arrangements — as soon as investors or co-founders with special terms (vesting, drag-along rights, a right of first refusal on shares) come on board, you'll need to switch to individual articles of association. Some banks, landlords, and business partners view the UG as a less established form compared to the GmbH, and given the low nominal capital's actual insufficiency for real business needs, banks and leasing companies often still require personal guarantees from the founders regardless. Finally, a director's duties — in particular, the duty to file for insolvency proceedings without delay (Insolvenzantragspflicht, § 15a InsO) — apply to a UG to exactly the same extent as to a GmbH, regardless of its modest capital.

7. Converting from a UG to a Classic GmbH

Once a company's accumulated capital (nominal capital plus reserve) reaches €25,000, it becomes eligible to convert to full GmbH status. Formally, this is carried out as a capital increase (Kapitalerhöhung) — either funded from the company's accumulated funds (Kapitalerhöhung aus Gesellschaftsmitteln, using the reserve) or through an additional cash or in-kind contribution from the shareholders. The resolution to increase capital must be notarized and entered in the Handelsregister; only then can the company drop the mandatory reserve requirement and the "(haftungsbeschränkt)" designation from its name, registering instead as a "GmbH."
