UG (haftungsbeschränkt) Formation Guide — Germany's Startup GmbH
The UG (haftungsbeschränkt) is a German limited-liability company requiring as little as €1 share capital. It is governed by GmbHG and is the go-to structure for founders with limited startup capital.
What Is the UG (haftungsbeschränkt)?
The Unternehmergesellschaft (haftungsbeschränkt) — abbreviated UG — was introduced in 2008 by the MoMiG reform to the GmbHG as a variant of the GmbH. It can be incorporated with as little as €1 share capital, compared to the €25,000 minimum of a full GmbH. The suffix "(haftungsbeschränkt)" must appear in every commercial document, invoice, and contract, and cannot be abbreviated. The UG enjoys identical legal status to a GmbH — full legal personality from Handelsregister entry under GmbHG §13.
- Minimum share capital: €1 (GmbHG §5a(1))
- Mandatory profit retention of 25% per year until reserves reach €25,000
- Legal form: variant of GmbH, governed by GmbHG in full
- Full limited liability — personal assets of shareholders not at risk
- Can convert to GmbH when share capital reaches €25,000
UG vs. GmbH — Key Differences
The UG and GmbH are legally almost identical. The two critical differences are the mandatory capital reserve accumulation requirement of §5a(3) GmbHG, and the inability to make contributions in kind (Sacheinlagen) during formation — UG capital must always be paid in cash.
| Feature | UG (haftungsbeschränkt) | GmbH |
|---|---|---|
| Min. share capital | €1 | €25,000 |
| Capital in kind (Sacheinlagen) | Not permitted | Permitted |
| Annual profit reserve | 25% until €25,000 accumulated | Not required |
| Conversion option | Converts to GmbH at €25,000 | N/A |
| Musterprotokoll eligible | Yes (up to 3 shareholders) | Yes |
| Supervisory board | Optional | Optional (mandatory for 500+ employees) |
Formation Process Step by Step
UG formation follows the same notarial procedure as a GmbH under GmbHG §2. The simplified Musterprotokoll (standardised articles) is permitted for formations with up to 3 shareholders and 1 director, reducing notary costs to approximately €200–400. Custom articles drafted by a lawyer cost more but allow flexibility in shareholder rights, drag-along clauses, and voting structures.
- Step 1: Draft articles of association (Gesellschaftsvertrag) or use Musterprotokoll
- Step 2: Notarial certification (Beurkundung) before a German Notar — GmbHG §2
- Step 3: Open a German business bank account and deposit share capital
- Step 4: File with Handelsregister via notary — notary fee ~€200–600
- Step 5: Receive Handelsregisternummer (HRB) and tax registration questionnaire
- Step 6: Submit Fragebogen zur steuerlichen Erfassung via ELSTER
The Mandatory Reserve Requirement
Under GmbHG §5a(3), a UG must allocate 25% of its annual net profit (Jahresüberschuss) to a statutory reserve (gesetzliche Rücklage). This reserve cannot be distributed to shareholders. Once the combined share capital and reserve equal €25,000, the UG may resolve to convert to a GmbH through a capital increase (Kapitalerhöhung) and notarial amendment. The conversion requires shareholder resolution and Handelsregister filing.
The mandatory reserve makes the UG a self-capitalising vehicle. A UG earning €20,000 net profit per year accumulates the full €25,000 reserve in approximately 5 years, after which conversion to GmbH is available. Until then, the reserve is locked and cannot be paid out as dividends.
Registered Address Requirement
The UG must have a German registered address (Sitz) as required by GmbHG §4a. A physical office is not mandatory — a virtual office address (Briefkastenanschrift) is sufficient for Handelsregister registration, Finanzamt correspondence, and business bank account opening. Virtual addresses in Berlin, Frankfurt, Düsseldorf, or Munich are available from €490 per year and ensure that official post from courts, tax authorities, and the Handelsregister is received and forwarded.
- German registered address mandatory under GmbHG §4a
- Virtual office address is sufficient — physical office not required
- Address visible in public Handelsregister entry
- Address changes require notarial amendment and Handelsregister re-filing
Tax Treatment of the UG
The UG is taxed identically to a GmbH. It pays Körperschaftsteuer (15%) plus solidarity surcharge (0.825%), and Gewerbesteuer at the municipal Hebesatz (combined effective rate ~28–33%). VAT registration is required once annual turnover exceeds €22,000. The mandatory 25% reserve allocation reduces distributable profit but does not reduce the taxable profit — tax is calculated before the reserve transfer.
| Tax | Rate | Basis |
|---|---|---|
| Körperschaftsteuer | 15% | KStG §23 |
| Solidaritätszuschlag | 0.825% | SolZG |
| Gewerbesteuer (Berlin example) | 14.35% | GewStG (Hebesatz 410%) |
| Combined (Berlin) | ~28–33% | KSt + Soli + GewSt |
| Dividend withholding tax | 25% + Soli | KapErtSt §43 EStG |
Annual Accounts and Bundesanzeiger Filing
Every UG must prepare annual financial statements (Jahresabschluss) comprising a balance sheet (Bilanz) and profit and loss account (GuV) under HGB §242. Small UGs qualifying under HGB §267(1) may file abbreviated accounts. The Jahresabschluss must be submitted to the Bundesanzeiger within 12 months of the financial year-end. Late filing triggers automatic fines starting at €2,500, escalating to €25,000 for persistent non-compliance.
- Jahresabschluss required under HGB §242
- Bundesanzeiger filing deadline: 12 months after financial year end
- Small company threshold (HGB §267): turnover ≤€8.8M, balance sheet ≤€4.4M, ≤50 employees
- Audit only required if UG exceeds medium-size thresholds under HGB §316
Banking for a UG
Opening a German bank account for a UG requires the notarised formation deed, Handelsregister extract, and valid ID of all directors. Traditional banks (Deutsche Bank, Commerzbank, Sparkasse) typically require in-person attendance. Fintech banks including Penta, Qonto, and Holvi offer remote account opening for UGs with the same Handelsregister requirement. The bank must confirm share capital deposit before the notary can file with the Handelsregister — even if the capital is €1.
Several German fintech banks accept non-resident UG directors for account opening via video identification. The account must be in the UG's name (not the founder's personal name) before the notary can certify the capital deposit confirmation letter required for Handelsregister filing.
Converting UG to GmbH
When the UG's accumulated reserve plus share capital reaches €25,000, shareholders may resolve to convert to a full GmbH by capital increase under GmbHG §5a(5). The conversion requires a shareholder resolution (Gesellschafterbeschluss), notarial certification, and Handelsregister amendment filing. The GmbH suffix replaces the UG suffix. All existing contracts, tax numbers, and bank accounts transfer automatically — no new company is created.
- Shareholder resolution required — GmbHG §5a(5)
- Notarial certification and Handelsregister filing required
- No new legal entity created — same company, new suffix
- Useful milestone: removes the mandatory reserve restriction
- Steuernummer and USt-IdNr remain unchanged after conversion
Frequently Asked Questions
What is the minimum capital for a UG in Germany?
Under GmbHG §5a(1), the minimum share capital for a UG (haftungsbeschränkt) is €1. In practice, most founders use at least €100–€500 to cover initial costs before revenue. However, any amount from €1 is legally valid. The capital must be paid in cash — contributions in kind (Sacheinlagen) are not permitted for UG formation.
How does the 25% profit reserve work for a UG?
GmbHG §5a(3) requires that 25% of annual net profit (Jahresüberschuss) be allocated to a statutory reserve each year. This reserve cannot be distributed as dividends. It accumulates until the total of share capital plus reserve equals €25,000, at which point the UG may convert to a GmbH. The reserve is an equity balance on the balance sheet, not a separate bank account.
How long does UG formation take in Germany?
UG formation using the Musterprotokoll typically takes 2–4 weeks from notary appointment to Handelsregister entry. Custom articles require additional drafting time. The Registergericht processes the filing in 1–4 weeks depending on the court. The UG has no legal personality until the Handelsregister entry is complete.
Can a non-German resident be the sole director of a UG?
Yes. GmbHG imposes no residency requirement on the Geschäftsführer (managing director). A non-resident director is fully valid. However, a local contact address for Finanzamt correspondence and legal service is advisable. If the director consistently exercises management outside Germany, the UG may have its effective management (Ort der Geschäftsleitung) located abroad, creating potential double-taxation issues.
Can I use the Musterprotokoll for a UG formation?
Yes, provided the formation has no more than 3 shareholders and 1 managing director. The Musterprotokoll is the standardised articles of association form introduced by MoMiG, and notary fees for Musterprotokoll formations are significantly lower (approximately €200–400 vs. €600–1,200 for custom articles). The template is very limited — any bespoke shareholder or governance provisions require custom articles.
Is a UG treated differently from a GmbH by German banks?
Some traditional German banks are reluctant to open accounts for UGs with very low share capital (e.g. €1–€100), viewing them as higher credit risk. Fintech banks such as Penta, Qonto, and Holvi are more willing. For higher-value transactions and trade finance, converting to a GmbH with €25,000 capital removes this friction. The UG is a fully legitimate legal form and is not inherently treated as a lesser entity for contracting purposes.
What are the total formation costs for a UG?
Using the Musterprotokoll: notary fees ~€200–400, court registration fee ~€150, total excluding capital approximately €500–700. With custom articles drafted by a lawyer: notary fees ~€600–1,200, legal drafting ~€500–1,000, court fee ~€150, total approximately €1,500–2,500. Professional formation services (including address) start from approximately €990. The share capital itself (minimum €1) is deposited into the company account and is available for business use after registration.
Does a UG pay VAT in Germany?
A UG is subject to German VAT (Umsatzsteuer) under UStG §2 if it carries out economic activity. It must register for VAT with the Finanzamt once annual turnover exceeds €22,000 (Kleinunternehmerregelung under UStG §19). Below this threshold it may opt for the small business exemption. A USt-IdNr (DE + 9 digits) is required for all intra-EU B2B transactions regardless of turnover.
Can a UG hold shares in other companies?
Yes. A UG can act as a holding company and hold shares in subsidiaries (GmbH, UG, or AG). Dividends received from a German GmbH subsidiary qualify for the §8b KStG participation exemption (95% exempt from Körperschaftsteuer). This makes even a UG with minimal capital an effective holding vehicle for German corporate structures, though the mandatory reserve restriction still applies to the UG's own profits.
What happens if a UG does not retain 25% of profits?
Failure to allocate the mandatory 25% annual reserve violates GmbHG §5a(3) and constitutes an unlawful distribution. The directors bear personal liability for any resulting loss to the company. The Finanzamt may also challenge the accounts. If a shareholder receives distributions that should have gone to the reserve, they are required to repay them. A Steuerberater reviews the annual accounts to ensure compliance.
How does a UG convert to a GmbH?
Under GmbHG §5a(5), once share capital plus accumulated statutory reserve equals €25,000, the shareholders resolve to increase capital to at least €25,000 via the existing reserve. A notarised shareholder resolution, updated articles of association, and capital increase documentation are filed with the Handelsregister. The Handelsregister amends the entry, replacing UG (haftungsbeschränkt) with GmbH. No new legal entity is created.
Is a UG suitable for a holding company structure?
A UG can serve as a holding company but the mandatory reserve requirement applies to profits of the UG itself. Since dividend income from German subsidiaries is 95% exempt under §8b KStG, a UG holding company typically accumulates little taxable profit, meaning the reserve requirement is rarely a material constraint in a pure holding scenario.
What documents are required to form a UG?
Required documents: valid passport copies of all shareholders and directors, current proof of address (utility bill or bank statement, dated within 3 months), and if using a legal entity as shareholder — current Handelsregister extract and articles of association of that entity. All foreign documents must be translated into German by a sworn translator. If a director cannot attend the notary, a notarised power of attorney is required.
