An address for the company register and trade registration. Representative, quickly set up and flexible.
In principle yes, provided the address can receive service of process and you are genuinely reachable there. A plain post box is not enough. How strictly the authority reads this in a given case is worth clarifying with your tax adviser first.
Between roughly €45 and 150 a month, depending on the provider and what is included. Plain mail addresses sit at the lower end; a registered seat with a nameplate and real reachability sits in the middle. In Altach the business address is €59 and the registered office €99 a month, both cancellable monthly.
No. A GmbH needs a registered seat, not its own office space. Plenty of small companies work remotely and use a rented registered-office address. What matters is that someone is genuinely reachable at that seat.
Three short steps, then I'll be in touch.
