It’s that simple
You need a BayernID account, which can easily be created with a username and password.
An online ID function (eID) is not required.
There is now also an application form for voluntary re-registrations.
Information is available on the KVR Trade Licensing Office website in eleven languages.
Important note: Don’t lose any time - after registering your business with the Trade Licensing Office, make sure to also register it online with the tax office without being prompted! Further information is available from the Munich Start-up Office on the “Registration” page.
