UG (haftungsbeschränkt) financial statements: the mini-GmbH explained

A UG is legally a GmbH

The UG is not a separate legal form; it is a GmbH founded under the simplified capital rule of § 5a GmbHG. That means the entire HGB apparatus applies without modification: a UG is a corporation under § 264 HGB and must prepare a balance sheet (Bilanz), an income statement (GuV) and, unless it is a micro entity, notes (Anhang). Preparation, shareholder adoption, filing and penalties follow the same rules as any GmbH.

In practice almost every UG is a micro (Kleinst) or small entity under § 267a / § 267 HGB, because the whole point of the form is to start small. That usually means no statutory audit, no Lagebericht, wide Anhang exemptions, and the ability to deposit a shortened balance sheet rather than publish a full one (§ 326 Abs. 2).

The mandatory 25% legal reserve (§ 5a Abs. 3 GmbHG)

The single feature that sets a UG's accounts apart from an ordinary GmbH's.

Because a UG starts with less than the €25,000 minimum capital of a normal GmbH, the law forces it to build capital from its own profits. Under § 5a Abs. 3 GmbHG the UG must transfer at least one quarter — 25 percent — of its annual surplus (the Jahresüberschuss, reduced by any loss carried forward) into a statutory reserve each year. The reserve may only be used to increase the share capital, to offset an annual deficit, or to cover a loss carried forward.

On the balance sheet this reserve appears within equity as a revenue reserve (gesetzliche Rücklage) under § 272 HGB, alongside the small subscribed capital figure. Getting this allocation right every year is the most common UG-specific error, so it is worth checking the reserve movement each fiscal year.

The path from UG to full GmbH

The reserve requirement is a runway, not a permanent burden. Once the UG has accumulated enough capital — through the forced reserve and any additional contributions — to reach the €25,000 minimum share capital of a GmbH, the shareholders may resolve a capital increase from company funds and re-register the company as a plain "GmbH". At that point the § 5a reserve obligation falls away.

The conversion is a change of designation, not a new company: the same legal entity, tax number and continuity of accounts carry forward. The first set of statements after the change simply drops the mandatory reserve allocation and shows subscribed capital of at least €25,000.

What a UG typically files

• A micro UG may deposit (hinterlegen) a shortened balance sheet with the Unternehmensregister instead of publishing it, and can omit the Anhang if it shows a few figures beneath the balance sheet (§ 264 Abs. 1 Satz 5).
• A small UG files an abridged balance sheet and reduced notes, without the income statement.
• No statutory audit applies to a micro or small UG (§ 316 HGB), and no Lagebericht is required (§ 264 Abs. 1 Satz 4).
• Filing is still mandatory even for a dormant UG, within twelve months of the balance sheet date (§ 325 HGB); missing it triggers Federal Office of Justice penalties starting at €2,500.

Frequently asked questions

Does a UG have to file annual accounts?

Yes. A UG is a GmbH, so it must prepare and file statutory statements under the HGB and § 325. Even a dormant UG with no activity must file, and missing the deadline leads to automatic penalties from the Federal Office of Justice starting at €2,500.

What is the 25% reserve a UG must build?

Under § 5a Abs. 3 GmbHG a UG must transfer at least a quarter of its annual profit, reduced by any loss carried forward, into a statutory reserve each year. The reserve can only be used to raise the share capital or to cover losses.

When does a UG become a GmbH?

Once its accumulated capital reaches the €25,000 GmbH minimum, the shareholders can resolve a capital increase from company funds and re-register as a GmbH. The mandatory 25 percent reserve obligation then ends.

Does a UG need an audit?

Almost never. A statutory audit applies only to medium-sized and large corporations (§ 316 HGB), and a UG is virtually always a micro or small entity. Micro and small companies are audit-exempt.

Where does the UG reserve appear on the balance sheet?

Within equity, as a statutory revenue reserve (gesetzliche Rücklage) under § 272 HGB, shown next to the subscribed capital. Its movement should be reconciled each fiscal year.
