Single-member GmbH (Einpersonen-GmbH)
Also: Einpersonen-GmbH, Ein-Personen-GmbH, one-person GmbH
In short
A single-member GmbH has only one shareholder, who is usually also its managing director. The same rules apply to it as to any GmbH, including the €25,000 share capital.
Single-member GmbH (Einpersonen-GmbH) explained
The GmbH Act expressly allows formation by one person (Sec. 1 GmbHG). Since the GmbH reform of 2008, it no longer requires additional security for the unpaid part of the share capital. Two special features remain: the sole shareholder must record their resolutions in writing and sign them without delay (Sec. 48 (3) GmbHG). If they are also the sole managing director, the prohibition of self-dealing under Sec. 181 BGB applies to their transactions with the GmbH, and these transactions must be recorded in minutes (Sec. 35 (3) GmbHG). With less capital, the same is possible as a single-member UG.
