Now that is bs. Because you also need to register with the tax authorities (Finanzamt) to get your tax id after that. Oh, and if you want to do your VAT declarations ("Umsatzsteuervoranmeldung") yourself, don't forget to request a digital certificate for ELSTER, which is sent - yes- via snail mail. And good luck if you want a EU VAT id, which is another separate step/appointment. And when you want to pay out first dividends you are in for a surprise when the tax account asks all of the shareholders/owners of the GbR/GmbH for their proof of church membership (for dividends tax), which you have to request individually from the Finanzamt just to send it back to them later...
