Complete Guide: Legal Requirements for Registered Business Address in Vietnam 2026

Are you planning to set up a company in Vietnam but unsure whether your office location can legally be used as a registered business address? For foreign investors, misunderstandings about the legal requirements for a registered business address in Vietnam are common and can create unexpected obstacles during company registration and compliance procedures. What types of addresses are allowed? Which locations are restricted? And why does this requirement matter more than many investors initially expect? This article addresses these key questions and helps clarify what foreign investors need to know before choosing a registered business address in Vietnam.

What is a Registered Business Address in Vietnam?

A registered business address in Vietnam is the official legal location where a company is established and legally domiciled. This address must be a clearly identifiable physical location within the territory of Vietnam and is used for administrative management, tax registration, official correspondence, and communication with competent authorities. Under Article 42 of the Law on Enterprises 2020, as amended by Law No. 76/2025/QH15 (effective from 1 July 2025), a company’s head office must be located in Vietnam and specified by a complete postal address, including house number, street, ward, district, and city or province, together with contact information such as a phone number and email address (if any). This registered business address serves as the primary reference point for the Business Registration Authority, tax authorities, and other state agencies throughout the company’s operation.

Legal Requirements for a Registered Business Address

To successfully register a company in Vietnam, foreign investors must declare a registered business address that satisfies both legal and practical requirements. First, the address must be a real and physical location within Vietnam, capable of lawful use as a registered office. It must exist in reality, be reachable, receive official correspondence, and allow inspections by competent authorities when required. The use of fictitious, non-existent, or overseas addresses is strictly prohibited. In practice, shared offices or business centers may be accepted, provided the premises are legally approved for business use and supported by valid lease or service agreements.

In addition, the registered business address must not be a residential apartment, unless the area is explicitly approved for commercial or mixed-use purposes. Pursuant to Point c, Clause 8, Article 3 of the Housing Law 2023, residential apartment units may not be used for non-residential purposes, including business registration or office operations. Only designated commercial floors, service areas, officetel units, or other non-residential spaces stated in the construction permit or project approval may be used. Using a residential apartment as a business address may result in rejection of registration applications, administrative penalties, and mandatory rectification measures, including a forced change of address and potential tax-related enforcement.

Furthermore, the registered address must be clearly and fully described in accordance with Vietnam’s official administrative addressing system, enabling authorities to identify the exact physical location. Generally, the address should include the street number and name, ward or commune, and city or province, and must reflect the updated administrative names following the 2025 mergers of districts and wards. The declared address must be consistent with the lease agreement or ownership documents and comply with official postal and administrative standards.

Finally, the company must have legal proof of the right to use the registered address. Acceptable documents typically include a valid lease or service agreement with the lawful owner or authorized lessor, ownership and land-use right certificates where applicable, or written confirmation in cases of sublease or shared office arrangements. These documents are mandatory during the Investment Registration Certificate (IRC) application process to evidence the project location. While they may not always be physically submitted for the Enterprise Registration Certificate (ERC), the address must remain legally valid and available for post-registration inspection. Tax authorities may conduct verification or on-site inspections, and failure to maintain contact or justify absence at the registered address may trigger tax-related enforcement measures.

What If the Company Does Not Operate at Its Registered Address?

Vietnamese authorities apply a risk-based management approach to ensure that companies maintain an actual and identifiable physical presence at their registered business address. Under the Law on Tax Administration and Decree No. 125/2020/ND-CP, as updated in 2025, if a company cannot be contacted or verified at its registered location, tax authorities may classify the enterprise as “not operating at the registered address” (Status 06). Once this status is imposed, the company will be blocked from issuing electronic invoices, effectively suspending its ability to conduct commercial transactions.

In addition to operational disruption, the company may face administrative penalties for providing inaccurate information or failing to properly notify an address change, with fines typically ranging from VND 10,000,000 to VND 30,000,000. If the violation is not remedied within the prescribed timeframe, the Business Registration Office may initiate procedures to revoke the Enterprise Registration Certificate (ERC), resulting in forced suspension of business activities.

Particular attention should be paid to the use of residential apartments as business addresses, which is considered a significant compliance risk in 2025. Vietnamese authorities increasingly rely on digital housing and administrative databases to cross-check registered addresses, and in certain cases, non-compliant businesses may be subject to immediate enforcement measures without prior on-site inspection.

Changing Registered Business Address: Legal Procedure

Legal Procedure Companies must update their registration within 10 days. Note that in 2025, many administrative units (districts/wards) have been merged or renamed.

Case 1: Relocating within the same Province or City

• Same Tax Management Area: Direct notification to the Business Registration Office to update the ERC.
• Different Tax Management Area: Even if moving within a newly merged city/district, if the managing tax office changes, you must file Form 08-MST to transfer your tax records before updating the ERC.

Case 2: Relocating to a different Province or City

• Step 1 (Tax): Finalize tax obligations and obtain a transfer confirmation from the current authority.
• Step 2 (Investment): Update the Investment Registration Certificate (IRC) first to reflect the new project location.
• Step 3 (Enterprise): Submit the dossier to the Business Registration Office in the new province for a new ERC.

Note on Administrative Mergers: If your office address changes only in name (due to government restructuring of districts/wards), you should update your ERC and electronic invoice information to ensure your tax deductions remain valid and consistent with the national database.

Can Foreign Companies Use Virtual or Shared Offices?

Yes, in principle, foreign-invested companies may use shared offices or virtual office arrangements provided that such arrangements are lawful, suitable for the registered business lines, and accepted by the relevant authorities. The permissibility of virtual or shared offices in Vietnam is not uniform and may vary depending on the nature of the business activities, licensing requirements, and post-registration compliance practices of tax authorities.

In major cities such as Ho Chi Minh City and Hanoi, shared offices and serviced offices are commonly used, particularly for consulting, trading, technology, and non-location-dependent service sectors. However, companies operating in conditional or regulated industries, or those requiring operational facilities, warehouses, laboratories, or customer-facing premises, may not be permitted to use virtual offices as their registered business address.

In practice, companies using shared or virtual offices are often subject to closer scrutiny during post-registration tax management, especially where physical presence cannot be readily verified. To mitigate compliance risks, companies should ensure that the premises are legally approved for business use, that a valid lease or service agreement expressly allows business registration, and that the arrangement enables receipt of official correspondence and accommodation of inspections by competent authorities when required. Where applicable under local practice, company signage should also be displayed at the registered address.

A lack of verifiable physical presence, particularly when combined with other risk indicators such as delayed tax filings or inconsistent declarations, may trigger tax enforcement measures, suspension of invoice issuance, or other administrative actions.

Conclusion

Choosing a compliant Registered Business Address in Vietnam is not merely a procedural step but a critical foundation for long-term legal and tax compliance. From initial company setup to ongoing operations, an incorrect or non-compliant address can trigger registration rejection, tax enforcement measures, or even license revocation. As regulations and administrative boundaries continue to evolve in 2026, foreign investors must ensure their registered address fully aligns with current legal requirements and industry-specific conditions.
