Registered office or business address?

Registered office versus business address in Austria: a legal view

The terms registered office and business address are often used in the same breath in Austria, yet in law they mean different things. While a registered office is a basic requirement for a company to exist at all, a business address can exist independently of it. So what follows from that in legal terms?

The business address does not have to be the same address as the registered office

This article explains the differences, covers key terms such as the address for service and sets out the legal requirements under Austrian company law.

1. Definitions and distinctions

1.1. Registered office (section 3 UGB) – a company's legal centre

The registered office (also called the seat of the company) is a company's official legal seat. It is entered in the commercial register and determines, among other things, which authorities and courts have local jurisdiction.

Key features of the registered office:

• Entered in the commercial register (section 3 UGB)

• Determines court jurisdiction for claims and official proceedings

• Has tax consequences (which tax office is responsible)

• May differ from the place of business or the business address

In Austria the registered office is often the same as a company's central administration, but it does not have to be. A company may, for example, have a place of business in another federal state while the legal registered office stays where it is.

1.2. Business address – a company's practical address

The business address is the address at which a company can be reached. It does not have to be identical to the registered office. In Austria it is possible to run a business address at another location, for example in a coworking space or a virtual office.

Key features of the business address:

• Not a mandatory legal requirement

• May differ from the registered office

• Often used for business correspondence (client contact, receiving post)

• May also be in a business centre or coworking space

📌 Example:

A company has its registered office in Vienna but uses a business address in Salzburg to serve clients there.

2. Address for service – what does that mean?

The term "address for service" matters particularly for corporations and other companies.

Definition:An address for service is an address at which a company can be reached in a legally binding way. Authorities and courts use it to deliver official documents (for example RSa/RSb letters, reminders, claims or official notices).

Requirements:

• There has to be genuine physical reachability

• Deliveries have to be accepted by authorised persons (managing directors or persons authorised to accept service)

• It cannot simply be a PO box, unless that box is a physical letterbox declared as an address for service

📌 Why this matters for companies:

For virtual offices or postal addresses in particular it is important to secure an address for service so that legal validity is not put at risk.

4. Legal requirements for a registered office and business address in Austria

4.1. The legal basis for the registered office

• Under section 3 UGB the registered office has to be entered in the commercial register.

• The seat is to be set where the actual administration takes place (the centre of decision-making).

• For corporations (GmbH, AG, FlexCo) the seat has to be set out in the articles of association.

4.2. Requirements for the business address

• A business address is not required by law, but it is sensible to have one.

• If an address for service is used, it has to meet the requirements of the Service of Documents Act.

5. Tax consequences: registered office versus place of business

The registered office determines which tax office is responsible, but a place of business can trigger additional tax obligations.

Registered office and tax liability:

• The registered office determines the competent tax office.

• Companies pay corporation tax and VAT under Austrian tax law.

Place of business and tax liability:

• If a physical place of business exists (a branch, for example), it can trigger an additional tax liability.

• As a rule, trade tax is payable in the municipality where the place of business is located.

6. Can a business address be used as a registered office?

Yes, under certain conditions. A business address can be entered as the registered office if the business is actually run from there.

Permitted:

✔ Using a business address as the registered office if administration happens there

✔ Using a virtual office with an address for service

Not permitted:

❌ Using a purely postal address with no physical presence

❌ Letterbox companies with no actual business activity

📌 Careful: giving a sham address as the registered office risks legal consequences.

In summary

The difference between a registered office and a business address carries considerable legal weight in Austria.

• The registered office is a company's legal seat and determines both the place of jurisdiction and which tax office is responsible.

• The business address is an operational address that may differ from the registered office.

• An address for service is necessary for many companies so that official documents can be received.

• The place of business, in turn, is a physical establishment with tax consequences.

When choosing a registered office and business address, companies should look carefully at which options make legal sense and are commercially advantageous.
