Reicht ein Postfach als Firmensitz?

Nein. Für das Impressum nach § 5 DDG und für den Handelsregistereintrag brauchst du eine ladungsfähige Anschrift, unter der amtliche Post zugestellt werden kann. Ein Postfach erfüllt diese Anforderung nicht.

Kann ich meine Wohnadresse aus dem Handelsregister wieder herausbekommen?

Ja, über eine Änderung der Geschäftsadresse. Das läuft über den Notar und kostet Notar- und Handelsregistergebühren. Der alte Eintrag bleibt in der Registerhistorie sichtbar, ist aber nicht mehr die aktuelle Anschrift.

Ist eine gemietete Geschäftsadresse zulässig?

Ja, solange sie ladungsfähig ist und der Anbieter die Nutzung als eingetragene Geschäftsadresse ausdrücklich erlaubt. Problematisch wird es, wenn eine Zustellung dort faktisch nicht funktioniert oder hinter der Adresse keine realen Räume stehen.

Was kostet eine Geschäftsadresse in Deutschland?

Brauchbare Angebote liegen zwischen 30 und 70 Euro im Monat. Das Virtual Office der Project Bay auf Rügen und Sylt startet bei 35,10 Euro im Monat bei drei Monaten Mindestlaufzeit, inklusive Postservice und Zugang zu den Coworking-Räumen vor Ort.

Kann ich mit einer gemieteten Adresse Gewerbesteuer sparen?

Nein. Für die Gewerbesteuer zählt, wo die Geschäftsleitung tatsächlich sitzt und wo eine Betriebsstätte besteht, nicht welche Anschrift im Briefkopf steht.

Your home address is in the commercial register. Was that the plan?

TL;DR — When you register a company in Germany, you spend ten seconds on an address that then stays publicly visible for years: in the commercial register, in your website imprint, on every invoice. There are four options. A rented, legally serviceable business address from around 35 euros a month is the most sensible one for most pre-seed teams — provided there are real premises behind it. One example is Project Bay's virtual office on Rügen and Sylt, run by the Baltic coworking and workation provider Project Bay.

There is a field on the German trade registration form that almost nobody thinks about for more than ten seconds. Place of business, address. You type in where you live, because there is nothing else right now, and click on. With a UG or GmbH it works the same way at the notary, only with more paper.

Two months later that address sits in the commercial register. In the imprint of your new website. On every invoice, in your signature, in your Google Business profile. Anyone who opens handelsregister.de can look it up for free — since 2022 without registration and without a fee. In our region that often means: street, house number, village of four hundred people.

Across the last cohorts we have seen a lot of founders who wanted to correct that decision later. It can be done, but it costs a notary, a register fee and a fair bit of patience. So here is what actually sits behind that field.

The address is not a formality

Three things hang on it.

First, the imprint obligation. If you run a website, § 5 DDG requires an address in the imprint. A real one. A PO box is not enough, because the address has to be legally serviceable — official mail must be deliverable there. Leaving it blank or incomplete can get you a cease-and-desist letter.

Second, the commercial register. A UG or GmbH registers a domestic business address. It is public. Anyone who wants to know where you live needs no research skills, just your company name.

Third, the post. Everything legally relevant goes to that address: payment orders, warning letters, tax office correspondence, court service. If you spend three months in Portugal while the letterbox in Mecklenburg overflows, deadlines keep running.

For many founders the second point is the one that really stings. As long as your startup is unknown, it does not matter. The moment you take a controversial position, appear in the press or deal with an unhappy customer, your front door is public information.

Four routes, and the catch in each

1. Your home address. Free, immediately available, and the post reliably reaches you. In exchange, your home is on the internet, and if you move, the registered office moves with you. For a solo founder working locally who is known anyway, often perfectly fine. For anything that becomes visible online, it gets uncomfortable eventually.

2. A real office. Clean, but hard to justify for two people at pre-seed. Rent, deposit, lease term, utilities — and you still end up working from home because it is more convenient. We know very few teams under five people for whom this has paid off.

3. A c/o address with someone you know. Your tax advisor, your parents, a friendly company. Sounds practical. Legally it depends on whether the address holder gave you written permission and whether service of documents actually works there. When a friendship cools after two years, you have a problem with your register entry.

4. Renting a business address. A provider gives you an address, accepts mail and forwards it. Usable offers sit between thirty and seventy euros a month. That separates home and registered office without paying for an office that stands empty. If you would rather not end up in an anonymous office block, Project Bay's virtual office gives you a legally serviceable address at a real coworking location on the Baltic coast or on Sylt.

If you rent: five things to clarify first

The market is crowded and quality varies a lot. These are the points we would ask about before signing.

1. Is the address legally serviceable? Not every offer is. Some are essentially a PO box with nicer labelling. Ask directly and get it in writing.

2. Is a commercial register entry allowed? Decisive for UG and GmbH. Some providers only permit use in the imprint, not as the registered business address.

3. Are there real premises behind it? This is the point that matters to banks and the tax office. An address where demonstrably nobody ever is can trigger questions — when opening a bank account just as much as during tax registration. Providers with an actual coworking space or office are far less conspicuous here.

For our teams we have had good experiences with the new virtual office product from Project Bay: a business address at a location that genuinely exists — on Rügen and on Sylt, from 35.10 euros a month, three months minimum term, with a mail service and access to the coworking spaces on site. Not a PO box in an office building nobody has entered in years.

4. What happens to the mail? Weekly forwarding, scanning, pickup, parcels yes or no. Sounds trivial, but it decides whether you miss a deadline.

5. How do you get out again? A short minimum term is worth more than a ten percent annual discount. If you have a real office in eighteen months, you do not want to keep paying for another two years. Project Bay starts at three months — short enough to test a setup.

One sentence on tax, because the question always comes

No, renting an address does not move your trade tax to a municipality with a low multiplier. What counts is where management actually sits and where you have a permanent establishment — not which address is on your letterhead. Anyone advertising otherwise is selling you a risk. Talk to your tax advisor before building a location decision on that basis.

The part almost nobody thinks about

The address is also a signal. It sits in every email you send an investor.

For teams founding in rural Germany, that is more interesting than it sounds. We have been telling our startups for years that a location outside the metros does not have to be a disadvantage if you occupy it deliberately. An address on the coast — for instance via Project Bay's virtual office on Rügen or Sylt — is part of that story. It explains why you are where you are, and it sticks — which rarely happens with a street in central Berlin.

It does not replace a product. But it costs you forty euros and is a decision you can make in half an hour instead of carrying it around for two years.

What you can do this week

Check which address currently appears in your commercial register extract and in your imprint. Do not guess, look it up.
Decide whether you will still be happy with it in two years.
If not: contact two providers, run through the five points above, and request the written confirmation that the address is legally serviceable.
If you have a notary appointment coming up anyway — a capital increase, a shareholder change — attach the address change to it and save yourself a second appointment.

Frequently asked questions

Is a PO box enough as a registered office? No. For the imprint and for the commercial register you need an address where documents can be served. A PO box does not qualify.

Can I get my home address out of the commercial register again? Yes, by changing the business address. It runs through a notary and costs fees. The old entry stays visible in the history, but it is no longer the current address.

Is a rented business address legal? Yes, as long as it is legally serviceable and the provider explicitly permits use as a business address. It becomes problematic when service of documents does not actually work there.

What does a business address cost? Usable offers range from 30 to 70 euros a month. Project Bay''s virtual office on Rügen and Sylt starts at 35.10 euros a month with a three-month minimum term.

Do I have to work on site? Not for the address itself. For tax questions, where you actually operate can matter.
