Converting a UG to a GmbH in Germany 2026: Requirements, Costs and Process

The UG (haftungsbeschränkt) is Germany's low-cost entry into limited liability – you can start with as little as €1 in share capital. But as your business grows, you'll eventually face a natural question: when and how do you convert your UG into a full GmbH? This article explains the requirements, the two routes to the capital increase, the step-by-step process, and the costs involved in 2026.

Key Points at a Glance

• Not a true conversion: UG and GmbH are the same legal form (§ 5a GmbHG). You don't found anything new – you raise the share capital to €25,000 and change the name suffix.
• Requirement: Registered share capital must be increased to at least €25,000, with at least €12,500 paid in.
• Two routes: Convert reserves into share capital (capital increase from company funds) or pay in fresh cash (cash capital increase).
• Costs: Typically €800–2,500 – significantly cheaper than founding a new GmbH.
• Tax-neutral: The conversion triggers no income tax, because no assets change hands.
• Mandatory? No. Even with €25,000 in capital you may stay a UG – converting is voluntary.

UG and GmbH: The Same Legal Form, Just a Variant

Many people think the UG is a separate legal form. Legally it isn't: the UG (haftungsbeschränkt) is governed by § 5a of the German Limited Liability Companies Act (GmbHG) and is simply a variant of the GmbH with a lower starting capital. That's why the "conversion" is technically not a conversion under the Transformation Act (UmwG), nor a change of legal form. You transfer no assets and found no new company – the legal entity stays the same; only its outer form changes.

Concretely, two things happen in a single notary appointment:

1. The share capital is raised to at least €25,000 through a capital increase.
2. The name suffix "UG (haftungsbeschränkt)" is replaced by "GmbH" (amendment to the articles).

This exact structure is what makes the process cheap and tax-neutral. The UG's special status ends automatically: under § 5a (5) GmbHG, the UG-specific rules – above all the reserve requirement – no longer apply once share capital reaches or exceeds €25,000.

When Is the Conversion Worth It?

The UG comes with several restrictions that become more limiting as the business scales:

• Mandatory reserve requirement: 25% of annual profit must be set aside in a statutory reserve each year (§ 5a (3) GmbHG) until share capital reaches €25,000. This reserve is restricted and can only be used for the capital increase or to offset losses.
• Lower credibility: Banks, investors and business partners often view the GmbH as more established – the "(haftungsbeschränkt)" tag signals thin equity.
• No in-kind contributions: At UG founding, contributions in kind are not permitted (§ 5a (2) GmbHG); share capital must be paid fully in cash.

A common misconception: the reserve requirement does not end automatically once your equity or reserves cross the €25,000 mark. It ends only when you raise the nominal, registered share capital to €25,000 through a formal capital increase. Postpone that for years, and you must keep tying up 25% of your profit.

The Core Requirement: €25,000 Share Capital

The single most important criterion: the future GmbH's share capital must be at least €25,000 (§ 5 (1) GmbHG). Of that, at least €12,500 must actually be paid in at the time of filing (§ 7 (2) GmbHG). As a UG, you have two ways to build this capital – and they differ significantly in effort, cost and requirements.

Two Routes to the GmbH: Reserves or Cash Injection

The route you choose often decides the total cost:

Route 1 – convert reserves: The 25% reserves accumulated since founding are reclassified into registered share capital. The German Federal Court of Justice has confirmed that a UG may use a capital increase from company funds for this – the UG's ban on in-kind contributions does not stand in the way, because the company becomes a full GmbH the moment it reaches €25,000 (BGH, decision of 11 April 2011, II ZB 9/10). The catch: the resolution must be based on an audited balance sheet, which means additional auditor fees.

Route 2 – cash injection: You or additional shareholders pay in the missing amount directly, without waiting for reserves to accumulate. For a UG with, say, €1,000 in share capital, that would be €24,000, of which at least the €12,500 threshold must be paid in. This route is simpler and faster because no audited balance sheet is required. For the mechanics of the increase, see our article on the GmbH capital increase.

Step-by-Step: How the Conversion Works

The conversion is carried out through a capital increase followed by an amendment to the articles of association:

1. Shareholders' resolution: All shareholders approve the capital increase and the change of name suffix – notarisation is mandatory.
2. Carry out the capital increase: Share capital is raised to at least €25,000 – via reserve conversion or cash injection, depending on the chosen route.
3. Notary appointment: The notary certifies the resolution and the amended articles and files the change with the commercial register.
4. Commercial register entry: The local court records the capital increase and the new company name. The GmbH is only legally effective from this point.
5. Update all company documents: Letterheads, website, contracts, imprint, and invoices must reflect "GmbH". The transparency register should also show the new name.

From notarisation to entry, the process usually takes one to three weeks, depending on the workload of the competent register court.

Conversion Costs in 2026 at a Glance

Costs depend primarily on the share capital, the chosen route, and the notary's complexity. Notary and court fees follow the GNotKG and rise with the transaction value:

If you take the simple cash-injection route, you tend to stay at the lower end of the range because the costly audit is avoided. Either way, the conversion is significantly cheaper than a full GmbH incorporation from scratch – and faster, since many formalities are already done.

Tax Implications of the Conversion

The conversion itself is tax-neutral: it does not constitute a sale or transfer of assets and does not trigger income tax. Under Route 1, the accumulated reserves are reclassified as registered share capital – a purely legal bookkeeping entry, not a taxable distribution. So no capital gains tax arises.

Under a cash injection from outside (Route 2), shareholders pay the amount from already-taxed funds – there is no tax deduction for the contribution, but no extra burden either. The paid-in capital simply increases the acquisition cost of the shareholding.

What Changes After the Conversion

Once the commercial register entry is made, the GmbH is legally and commercially in effect. Key changes:

• The company suffix changes from "UG (haftungsbeschränkt)" to "GmbH".
• The 25% reserve requirement no longer applies – profits can be fully distributed.
• Creditworthiness and business reputation typically improve.
• Accounting obligations stay the same: double-entry bookkeeping, annual financial statements, and publication in the Federal Gazette.

Common Mistakes That Delay the Conversion

• Confusing reserves with share capital. €25,000 in the bank or in reserves is not enough – only the formal increase of the nominal share capital ends the UG status.
• Forgetting the audited balance sheet. If you convert via reserves, an audited balance sheet is mandatory – otherwise the register court rejects the filing.
• Not updating the name everywhere. If "UG" remains on invoices or in the imprint, you risk competition-law warnings and customer confusion.
• Going to the notary without current bookkeeping. If the annual profit or reserve isn't cleanly documented, the whole process stalls.

Norman Keeps Your Numbers Conversion-Ready

Whether you convert via reserves or a cash injection, both routes require clean, provable bookkeeping. Norman automates exactly that for GmbHs and UGs:

• AI bookkeeping sorts receipts GoBD-compliant and keeps the profit reserve traceable at all times.
• The annual statement is generated at the push of a button from ongoing entries – the basis for Route 1.
• VAT returns, corporate tax and e-invoicing run straight from your receipts.

That way the €25,000 is provable when the notary appointment comes – and your GmbH bookkeeping keeps running afterwards with no extra effort. Bookkeeping is always free.

Frequently Asked Questions About Converting UG to GmbH

Can you simply convert a UG into a GmbH?

Yes. Because UG and GmbH are the same legal form, you don't need a new incorporation. You raise the share capital to at least €25,000 and have the notary change the company name from "UG (haftungsbeschränkt)" to "GmbH". The commercial register entry makes the GmbH legally effective.

What does it cost to convert a UG into a GmbH?

Usually between €800 and €2,500, depending on the route. That includes notary and commercial register fees; the reserve route adds the cost of an audited balance sheet. The cash-injection route is usually cheaper.

Do I have to convert my UG once I reach €25,000?

No. Even with equity of €25,000 or more, you may remain a UG. Converting is voluntary. Only the formal increase of the share capital ends the UG's reserve requirement.

Is the conversion taxed?

No. The conversion is tax-neutral because no assets are transferred or sold. Neither reclassifying the reserves nor a cash injection triggers income or capital gains tax.

How long does the conversion take?

After the notary appointment, the commercial register entry usually takes one to three weeks. Adding preparation (resolution and, if needed, an audited balance sheet), you should plan for a few weeks depending on the route.

Summary: A Cost-Effective Milestone

Converting a UG to a GmbH is the natural next step once your business has grown. It's not a fresh incorporation but a capital increase with a name change – cheaper than a GmbH from scratch and tax-neutral. The key decision is the route: convert reserves or pay in fresh cash. With solid bookkeeping in place, you'll have all the numbers ready when the time comes.
