Set up a sole proprietorship: business address for the self-employed
Protect your private address with a professional business address in 1010 Vienna. Suitable for trade registration and the GISA entry.
What is a sole proprietorship (e.U.)?
The sole proprietorship is the simplest and most common legal form in Austria. As a sole proprietor you are the only owner and make all decisions yourself. From an annual turnover of 700,000 euros, or voluntarily, you have the option to register in the commercial register as a registered trader (e.U.).
Advantages of the sole proprietorship:
- Simple and quick formation without a notary
- No minimum share capital required
- Full decision-making freedom as the sole owner
- Lower running costs (no publication obligations)
- Small-business scheme available (up to 55,000 € turnover/year)

Frequently asked questions about the sole proprietorship
Can I use the virtual office address for my trade registration?
Yes, our address is suitable for trade registrations. You receive a contract that you can submit as proof of location to the trade authority.
Do I need a business address as a small business?
Yes, even as a small business you have to provide a business address during the trade registration. You also need an address for your imprint if you run a website.
What is the difference between a sole proprietorship and an e.U.?
A sole proprietorship is the legal form. You receive the additional designation 'e.U.' (registered trader) once you are entered in the commercial register. This is mandatory from 700,000 € annual turnover or possible voluntarily.
Can I use my private address as a business address?
In principle yes, but your private address then becomes publicly visible (imprint, GISA, invoices). With our virtual office solution you protect your privacy.
How quickly can I set up my sole proprietorship?
The business address is available after the contract is signed. The trade registration itself can often be completed within a few days.
