GmbH vs. UG: Which Legal Entity Should You Choose for Your German Startup?

Every founder incorporating in Germany faces the same first question: GmbH or UG? The answer is straightforward in most cases, but the details matter, especially if you plan to raise capital later.

The short answer

If you are building a venture-backed startup, choose the GmbH. If you are testing an idea solo and want liability protection at minimal cost, start with a UG.

That covers eighty percent of cases. The remaining twenty percent is where it gets interesting.

What is a GmbH?

A GmbH (Gesellschaft mit beschränkter Haftung) is Germany's standard limited liability company. It requires EUR 25,000 in share capital, of which at least EUR 12,500 must be deposited before registration. The company is registered with the Handelsregister (commercial register) after a notarized formation deed.

The GmbH is the default entity for any serious business in Germany. Banks, investors, enterprise clients, and government agencies all expect it. There is no credibility discount.

What is a UG?

A UG (haftungsbeschränkt), sometimes called the "Mini-GmbH", is a variant introduced in 2008. It offers the same liability protection as a GmbH but allows incorporation with as little as EUR 1 in share capital.

The catch: a UG must retain 25% of its annual net profit until accumulated reserves reach EUR 25,000. At that point, you can convert to a full GmbH (though you are not required to).

Capital requirements compared

The EUR 25,000 for a GmbH is not a fee. It is company money. After registration, the capital sits in the company's bank account and can be used for business expenses. It is not dead money.

When the GmbH is the right choice

You plan to raise venture capital. Every institutional investor in Germany expects a GmbH. If you incorporate as a UG and then approach VCs, the first item on their list will be conversion. That costs notary fees, time, and sometimes a pause in fundraising while the commercial register catches up. Start right.

You have co-founders. A GmbH's established legal framework handles multi-shareholder dynamics better. Articles of association, shareholder agreements, and cap table management all work more smoothly with a GmbH.

You need credibility with enterprise clients. Some large companies have internal procurement rules that filter out UGs. Whether this is rational is debatable. It is real.

You can afford EUR 25,000. If the capital is available (whether from savings, a founding loan, or friends and family), there is no reason to choose the UG.

When the UG makes sense

You are a solo founder testing a business idea. You want liability protection without committing EUR 25,000 to a company that might pivot or shut down in six months. The UG gives you a real legal entity for under EUR 500 in total setup costs.

You need a personal holding vehicle. A common setup for founders: establish a UG as your personal holding, which then holds shares in the operating GmbH. The holding UG has no revenue initially, so the low capital requirement is practical. The tax benefits of this structure (roughly 1.5% effective tax on share sales vs. 26% as a private individual) far outweigh the modest setup.

You are bootstrapping with no external funding plans. If you are building a profitable small business and have no intention of raising institutional capital, a UG works fine indefinitely. Many agencies, consultancies, and SaaS micro-businesses run on UGs.

The holding structure angle

Most founders who ask "GmbH or UG?" should also be asking about holding structures. The optimal setup for a venture-track founder looks like this:

1. Personal holding UG, owned by you, costs under EUR 500 to set up
2. Operating GmbH, owned by your holding UG (and your co-founders' holdings)

When the operating GmbH is eventually sold or goes through a liquidity event, your holding UG receives the proceeds. Dividends and capital gains between German corporations are 95% tax-exempt. You only pay full tax when you distribute from the holding to yourself.

This structure must be in place before the operating GmbH gains significant value. Restructuring later triggers tax on the unrealized gain. Do it at incorporation or not at all.

Conversion: UG to GmbH

If you start as a UG and later want to convert, the process requires:

1. A shareholder resolution to increase share capital to at least EUR 25,000
2. A notarized amendment to the articles of association
3. Proof of capital deposit
4. Registration of the change with the Handelsregister

Cost: roughly EUR 1,000–2,000 in notary and registration fees. Timeline: 2–6 weeks for the register entry.

It is not complicated, but it is not free. If you know you will need a GmbH within twelve months, skip the UG.

Practical timeline and costs

GmbH formation: EUR 800–1,500 in notary fees, EUR 150 registration fee, plus EUR 25,000 share capital. Ready to operate in 2–6 weeks after notarization.

UG formation: EUR 300–600 in notary fees (less if using a model protocol), EUR 150 registration fee, plus your chosen share capital (minimum EUR 1). Ready to operate in 2–6 weeks.

Both timelines assume you already have a German bank account open. If not, add 1–4 weeks for account opening. This is often the real bottleneck.

Bottom line

Once you've chosen the entity, the step-by-step GmbH formation guide covers the full path from first decision to operating company. For the end-to-end view across entity choice, holding setup, registrations, and first-year duties, see the complete GmbH formation guide. The GmbH is the default. Choose it unless you have a specific reason to start smaller. The UG exists for founders who need liability protection without upfront capital. It is a legitimate tool, not a second-class entity. But know that the path from UG to GmbH costs time and money, and investors will expect the conversion before writing a check.

Pick the entity that matches where you will be in twelve months, not where you are today. And keep an eye on the EU Inc., a pan-European alternative proposed in March 2026 that could change the calculus for cross-border founders.
