Yes, a virtual office is fully compliant with the law—provided it serves as a business address to which legal notices can be served. While modern, location-independent work has long been the norm, German law often lags behind. Therefore, a mere post office box is not sufficient for registration in the commercial register or for a legally compliant legal notice.
To withstand any audit by tax authorities and government agencies, the chosen registered office must be a tangible location. Legally compliant providers address this issue: They offer founders, Freelancers and companies concepts that go beyond a „cheap office“ and meet all strict legal criteria. Another feature: Membership in the Bundesverband Business Center e.V.
Be wary of rock-bottom offers: Not every provider is legally sound. Dubious „mailbox companies" are often not recognized by authorities. With a professional solution, however, you can ensure the flexibility you need without jeopardizing your company’s legal credibility.
The Criteria in a Nutshell: What Makes a Business Address Legally Valid?
Cargo Capacity: Ensuring Accessibility
It must be possible to deliver mail and packages on a permanent basis. Authorized individuals must be available on-site and able to accept mail (delivery to a mailbox alone is not sufficient). “Capable of receiving service” therefore means not only that mail can be delivered to this address, but also that a person authorized to receive service can actually be reached at the address. Thus, there must at least be the possibility of handing over a document to at least one authorized person.
Important registered mail, such as court documents (e.g., payment orders and lawsuits), must be officially delivered to the „jurisdiction" of the respective company. If someone wants to Rent a business address where mail can be received, by renting a virtual office, he ensures that important deadlines are not missed. Therefore, it is important that a staffed reception desk can ensure that important correspondence is received.
Office location – a physical presence rather than just a mailing address
A physical, actual office location must be in place. This must include a permanent office structure. A mere mailing address is not permitted. Tax authorities scrutinize this very closely and generally deny registration requests from unscrupulous providers.
There is a reception area with staff on site who accept mail; depending on the provider, the Mail Forwarding for Businesses takes over and welcomes visitors. When registering a business address that can be served with legal notices, the tax office requires that the actual location of business management be specified—often the founder’s home address. For public relations purposes and as a mailing address, the client uses the address Leipziger Platz 15—without the “c/o” notation.
There must be a fully functional office infrastructure in place, meaning it must be possible at any time to Office for Rent or Booking Conference Rooms. It is therefore not permissible for a provider to have, for example, „only" 3 offices at a given location, yet have hundreds of companies registered there.
Transparency in External Relations and Public Image
Either it must be possible to attach a company sign to the building, or the company name must be listed on the mailbox. A reputable office location is crucial and builds trust, because a legally valid business address is of little use if the location is unknown or questionable.
What does „permanent establishment" mean under Section 4 of the German Trade Regulation Act (GewO), and is a virtual office considered a permanent establishment?
According to Section 4(3) of the Trade Regulation Act, a branch office exists when an independent commercial activity is actually carried out for an indefinite period of time and through a permanent facility from that location. This definition of a permanent establishment can also be found in the Value-Added Tax Act and is the key factor in determining whether your virtual office legally qualifies as a permanent establishment.
For a long time, a closed-off and thus permanent office space was mandatory under Section 42 of the GewO (old version). Since a change in the law in 2009, the definition of „permanent facility" has been broadened. Today, government agencies also accept other work arrangements under certain conditions:
- Permanent position: Desks within an office community or in a shared office are usually accepted without any problems.
- Coworking & Flexible Solutions: Flexible workstations with a permanent component (e.g., storage space for business documents) may be sufficient. Important: Assign lockable cabinets or rolling file cabinets on a permanent basis.
- Drafting the Contract: When reviewing your service contract—often referred to as a „lease and service agreement"—make sure it does not include a short-term term.
Your choice of provider could affect your taxes
It is well known that tax authorities maintain a list of providers of business addresses. If service providers offer only post office boxes without the aforementioned infrastructure, tax authorities are increasingly refusing to issue tax identification numbers.
The Checklist for Government Agencies and Offices: What Points Are Important for Your Contract?
To ensure that nothing stands in the way of registering your business or obtaining your tax ID number, important criteria must be included in your new service agreement. Be sure to pay particular attention to the following points:
- Indefinite term: The service or lease agreement should be signed by you and your Virtual Office Providers be entered into for an indefinite term and without any restrictions on use.
- Fixed allocation: Consider the possibility of having a permanent facility—such as a locker or a workstation—assigned to you on a clear and permanent basis.
- Infrastructure Guarantee: Make sure that the provider you choose for your virtual office has sufficient staff and resources to perform all services independently and reliably.
- Structural stability: The goal here is to ensure that your company isn't just a „flash in the pan." So pay attention to your personnel and technical infrastructure to signal that your company's headquarters is here to stay.
Management vs. Shell Companies: Why Are Mailbox Addresses Alone Not Enough?
Due to the large number of dubious providers, government agencies and authorities are taking strong action against so-called „mailbox companies." So if you plan to rent a address that can be used for official service of process without verifiable business activity at the chosen location, you will sooner or later run into problems with the authorities.
Focus on Management (Section 10 of the German Fiscal Code)
Section 42(3) of the Trade Regulation Act states that a company’s registered office is considered a branch office only if the business operator has an office space set up for permanent use and also uses it on a regular basis. The Tax Code (AO) states the following in this regard:
Headquarters as the central hub of management: The relevant tax offices will only issue tax identification numbers if management activities can take place at the specified location within the meaning of Section 10 of the German Fiscal Code (AO). It is important to note that a company’s registered office is not the same as a permanent establishment. The permanent establishment is the location of management where decisions are made on a daily basis and day-to-day business operations are conducted. Therefore, the permanent establishment can also be, for example, your home office.
Exclude shell companies: Mere mailbox addresses that simply forward mail or calls do not meet the requirements for a branch office or corporate headquarters.
What do experts and associations say about minimum requirements?
The Bundesverband Business Center e.V. provides an excellent summary of the case law (based, among other sources, on Wank/Tettinger). The Bundesverband Business Center e.V. comments on the minimum requirements as follows:
- Ownership of rooms is not required: Actual control over the premises (and thus the rental of space) is sufficient. Separate, enclosed rooms or clearly defined areas are permitted. Modern business centers provide reception staff—and thus secretarial services—as well as conference rooms for shared use. These features support the recognition of a commercial establishment.
- Equipment options: In order for management to be recognized by the authorities, there should be at least one fully equipped office workstation that is permanently available.
- Regular attendance trumps mandatory attendance: As a business owner, you do not have to be present at your company’s headquarters around the clock. The only important thing is that you use the virtual office regularly and consistently to ensure that government agencies can reach you.
Don't compromise when choosing a location for your company headquarters. Instead, put your trust in reputable partners who have established long-standing structures.

FAQ – Frequently Asked Questions
Here you'll find answers to the most common questions we receive every day.
Is a virtual office legal?
Yes, a virtual office is fully compliant with the law—provided it serves as a business address that can be used for service of process. Therefore, a mere post office box is not sufficient for registration in the commercial register or for a legally compliant legal notice. To withstand any scrutiny by tax authorities and government agencies, the chosen registered office must be a physical location.
What does „permanent establishment" mean under Section 4 of the German Trade Regulation Act (GewO), and is a virtual office considered a permanent establishment?
According to Section 4(3) of the Trade Regulation Act, a branch office exists when a self-employed commercial activity is actually carried out for an indefinite period of time and from a fixed facility. Since a change in the law in 2009, the definition of „permanent facility“ has been broadened. Under certain conditions, authorities now also accept other work arrangements, such as desks within a shared office space, shared offices, or flexible workspaces with a permanent component.
When does the tax office refuse to issue a tax ID number for a virtual office?
When it comes to registering businesses and issuing tax ID numbers, companies with a registered office in a business center are treated very differently in many parts of Germany.

If service providers offer only post office boxes without any infrastructure, tax authorities are increasingly refusing to issue tax identification numbers.
Why aren't simple email accounts enough?
Mere mailbox addresses that simply forward mail or calls do not meet the requirements for a branch office or corporate headquarters. Government agencies and authorities are cracking down heavily on so-called „mailbox companies.“ If you rent an address that can be used to serve legal notices without verifiable business activities at the chosen location, you will sooner or later run into problems with the authorities.
