Virtual Office as Business Registration Address: Is It Legal?

This English version is translated from the Vietnamese original. In case of any discrepancy, the Vietnamese version prevails.

Using a virtual office as a business registration address is an increasingly popular choice among startup communities and small and medium enterprises in Vietnam. However, many business owners, chief accountants, and investors remain uncertain about one key question: is this model legal, and if so, what conditions must be met to avoid legal risks — particularly the risk of penalties from tax authorities? The article below by A&D Law Firm analyzes common misconceptions and compares them against actual legal regulations.

Misconception 1: "Virtual offices are illegal"

Actual regulation: Vietnamese law does not prohibit using a virtual office as a business registration address. What matters is that the address must meet the proper legal requirements for a principal place of business.

According to the Law on Enterprises 2020 (No. 59/2020/QH14), Article 42 – Principal place of business of an enterprise:

"The principal place of business of an enterprise is located on the territory of Vietnam, serves as the enterprise's contact address and is defined according to the boundaries of the administrative unit; it has a telephone number, fax number and email address (if available)."

The law does not require an enterprise to own or lease long-term premises at its principal place of business. The core requirement is: the address must actually exist on Vietnamese territory, be identifiable according to administrative units, and be reachable for contact. As long as the virtual office provider supplies an address that meets these elements, the registration is entirely lawful.

What you should do: Before signing a virtual office contract, carefully verify that the address on the contract clearly shows the house number, street name, ward/commune, district/province and city — this is mandatory information for business registration declarations.

Misconception 2: "One virtual office address cannot be registered for multiple enterprises"

Actual regulation: The Law on Enterprises 2020 contains no provision limiting the number of enterprises that can be registered at the same address. This is a common practical feature of the virtual office model — multiple enterprises can share a single commercial address.

However, the risk does not arise from the registration perspective but from the tax and inspection perspective. When dozens or hundreds of enterprises are registered at a single address, the tax authority may verify actual business activities and require enterprises to prove they are operating at that address.

What you should do: Choose a reputable virtual office provider with clear contracts that can assist in receiving mail, government notices, and provide reception facilities when needed.

Misconception 3: "Having an address is enough; no need to worry about registration details"

Actual regulation: According to the Law on Enterprises 2020 (No. 59/2020/QH14), the contents of the business registration application must be complete, including:

"The address of the enterprise's principal place of business, telephone number; fax number, email address (if available)."

Thus, the principal place of business address must be declared accurately from the initial registration application. Any discrepancy between the registered address and the actual operating address can lead to legal risks during inspections and audits.

According to the Law on Enterprises amending and supplementing certain provisions of the Law on Enterprises 2020 (No. 76/2025/QH15), the business registration application must include information about the enterprise owner. Enterprises should note the disclosure requirements when carrying out registration procedures.

What you should do: Ensure the virtual office address matches exactly with the address shown on the Enterprise Registration Certificate. Keep the virtual office lease contract and payment receipts as supporting documents.

Misconception 4: "Using a virtual office has no impact on taxes"

Reality: This is the misconception carrying the greatest latent risk. Tax authorities have the right to verify the actual location of an enterprise's principal place of business. If verification shows that an enterprise has no actual business activities at the registered address, fails to receive notices from government agencies, or the address provider is invalid, the enterprise may face:

• Classification as a high tax risk entity;

• Demands for explanation and documentation proving business activities;

• Consideration of tax code revocation or administrative penalties in the business registration field.

According to Decree 168/2025/NĐ-CP on business registration, business registration documents must be submitted to the business registration office where the enterprise has its principal place of business. This confirms that the principal place of business is a fundamental legal element, not merely a formality.

What you should do: Maintain the ability to receive mail and official documents at the virtual office address throughout the entire operating period. Consider registering an additional business location if the enterprise conducts actual production, processing, or direct sales activities.

Conditions for a virtual office to be accepted as a lawful business registration address

Summarizing current regulations, for using a virtual office as a business registration address to comply with the law, an enterprise must ensure:

1. The address actually exists on Vietnamese territory, identifiable according to administrative unit boundaries (house number, street, ward/commune, district/province, city);

2. It is reachable for contact: the address must be able to receive mail, telephone calls, and documents from government agencies;

3. A valid virtual office service contract: signed with a service provider with legal capacity, clearly stating the address, term of use and accompanying services;

4. Compliance with conditional business sector requirements: if the business license for a sector requires on-site inspection at the registered address (such as medical facilities, restaurants, food processing facilities, etc.), an enterprise cannot use a virtual office as its principal business registration address;

5. Consistent declared information: the address on the registration application, Enterprise Registration Certificate, invoices and tax records must be identical.

Business types that should not (or cannot) use a virtual office as their principal place of business

Not all enterprise types are suitable for the virtual office model. Some cases require special caution:

Business Type / Sector	Reason unsuitable for virtual office
Healthcare facilities, pharmaceuticals	Requires on-site inspection and compliance with material infrastructure standards at the operation location
Restaurants, food processing facilities	Authorities inspect food hygiene and safety conditions at the registered address/business location
Security companies, conditional security services	Business license requires the location to be inspected by public security authorities
Household businesses with fixed-location activities	Under Decree 168/2025/NĐ-CP, when a household business engages in activities at a fixed location, it must register its principal place of business at the location where such activities are conducted

For other business types and sectors — particularly technology enterprises, consulting firms, e-commerce, agencies, and brokers — a virtual office is entirely a lawful and cost-effective choice.

How to mitigate tax-related risks

To minimize the likelihood of being classified as high-risk in tax management, enterprises using virtual offices should note:

• Choose a provider with a clearly identified address, not listed in the register of "fictitious" addresses previously flagged by tax authorities;

• Maintain continuous lease contracts and fully retain payment receipts to present when required;

• Register supplementary business locations (if actual work locations exist elsewhere) to ensure transparency in disclosures to authorities;

• Promptly update when changing the principal place of business — delays in reporting address changes constitute a violation of business registration obligations;

• Designate a mail receiving point at the virtual office address: ensure all notices from tax authorities and business registration offices are received and responded to on time.

Summary: Using a virtual office as a business registration address — legal or not?

The short answer: Legal — if the address meets all legal conditions for a principal place of business under the Law on Enterprises 2020 (No. 59/2020/QH14) and the business sector does not require actual physical facilities at the registered address. The law does not require an enterprise to own or physically occupy premises at the registered address. What matters is that the address must actually exist, be identifiable according to administrative units, and the enterprise must maintain the ability to be contacted there throughout its operations.

The risk does not come from the virtual office model itself, but from enterprises failing to maintain contact capability, providing inconsistent information, or using an invalid address. Correctly identifying risks and establishing appropriate operational practices is the key to leveraging the benefits of a virtual office without violating the law.
