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 step-by-step process, and the costs involved.

Why Convert a UG to a GmbH?

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

• Mandatory reserve requirement: 25% of annual profit must be retained until share capital reaches €25,000
• Lower credibility: banks, investors and business partners often view GmbH as more established and trustworthy
• No in-kind contributions at founding: UG share capital must be paid in cash only

Once your capital reaches €25,000, the reserve requirement technically ends — but the 'UG' designation remains until you formally complete the conversion.

The Core Requirement: €25,000 Share Capital

To convert to a GmbH, your share capital must reach at least €25,000, with at least €12,500 paid in cash. There are two ways to get there:

• Organic growth via reserves: The accumulated 25% reserves are converted into share capital. Once reserves + existing capital = €25,000, you can proceed.
• Capital increase by cash injection: You or additional shareholders pay in the missing amount directly, without waiting for reserves to accumulate.

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:

• Shareholders' resolution: All shareholders approve the capital increase and the company name change — must be notarised.
• Capital increase: Share capital is raised to at least €25,000. If using accumulated reserves, the notary confirms the conversion in the commercial register filing.
• Notary appointment: The notary certifies the amendment to the articles and files the change with the commercial register.
• Commercial register entry: The local court records the new legal form. The GmbH is only legally effective from this point.
• Update all company documents: Letterheads, website, contracts, and invoices must all reflect 'GmbH' instead of 'UG'.

Conversion Costs at a Glance

The costs depend primarily on the share capital amount and the notary's complexity fees:

• Notary fees: approx. €300–800
• Commercial register fees: approx. €150–300
• Tax advisor / lawyer (optional but recommended): approx. €500–1,500

Total costs are typically around €800–2,500 — significantly less than forming a new GmbH from scratch.

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. The accumulated reserves are simply reclassified as registered share capital — a purely legal bookkeeping entry, not a taxable distribution.

If the capital increase is funded by external cash injections from shareholders, those funds must come from already-taxed income — there is no tax deduction for the contribution.

What Changes After the Conversion

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

• The company designation 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 remain the same (double-entry bookkeeping, annual financial statements)

Summary: A Cost-Effective Milestone

Converting a UG to a GmbH is the natural next step once your business has grown. It's cheaper than a fresh incorporation and tax-neutral. With solid bookkeeping in place, you'll have all the numbers ready when the time comes.
