Vietnam offices face tax compliance risks
Foreign firms looking to test Vietnam’s market often start with a representative office, a legal structure that lets them maintain a local presence without engaging in direct revenue‑generating activities. While the arrangement sidesteps many of the obligations that apply to branches or subsidiaries, it does not eliminate compliance duties, and the personal income tax (PIT) risk for the chief representative remains a notable concern.
What a representative office can and cannot do
Vietnamese regulations draw a clear line around the activities an RO may perform. Permitted actions include market research, brand promotion, liaison between the head office and local partners, and the display of products without selling them. The office may also gather and analyse information, act as a communication channel, and coordinate with local entities. It is expressly prohibited from conducting direct commercial activities, such as signing contracts or generating revenue.
Violating these limits can trigger administrative penalties, suspension of the office’s operations, or even revocation of its licence. Moreover, unauthorized commercial activity may create a permanent establishment (PE) in Vietnam, exposing the foreign parent to corporate income tax on profits attributable to that PE.

Ongoing compliance obligations
After an RO is approved, it must meet a series of recurring reporting requirements. Each year, the office files an activity report with the provincial Department of Industry and Trade by January 30, detailing operations, staff, and financial data. Even though it does not earn revenue, it must obtain a tax identification number and register for foreign contractor tax on cross‑border payments, as well as for PIT on employee wages.
The licence is generally valid for five years, and any changes—such as a new address, head‑office details, or legal representative—must be reported and approved. Labor compliance is also mandatory: the RO must enter into labor contracts, enroll staff in social, health, and unemployment insurance schemes, and secure work permits for foreign employees.
Corporate income tax (CIT) does not apply to the RO itself if it only carries out liaison functions. Yet, if tax authorities deem the office a PE, the head office’s profits linked to the RO could be taxed in Vietnam. The more immediate tax duty falls to PIT, where the RO must withhold and declare taxes for its staff.

Personal income tax risk for the chief representative
The chief representative’s tax exposure can extend beyond the salary reported on the payroll. During tax inspections, authorities often review expenses incurred by the RO to decide whether they constitute taxable benefits for the chief representative. Items lacking valid invoices, those that cannot be justified as serving a legitimate business purpose, or expenses that appear personal rather than operational are scrutinised closely.
Typical areas of focus include accommodation and housing costs, vehicle and transport fees, entertainment and hospitality outlays, and payments to third parties without sufficient documentation. If an expense cannot be substantiated as a genuine operating cost, the tax office may reclassify it as employment income, subject it to progressive PIT rates, and hold the chief representative personally liable for the tax due.
To mitigate this risk, foreign firms should keep complete invoices and supporting documents for all outlays, adopt internal policies that clearly separate business from personal spending, and enforce strict expense‑approval and reimbursement procedures. Robust documentation and regular internal reviews are essential to prevent unexpected tax reassessments.

In practice, these requirements mean that the chief representative must be meticulous about how the office funds its day‑to‑day activities. For staff on the ground, the distinction between a reasonable business travel cost and a perk that could be taxed is often a thin line, and the burden of proof rests with the office to show that each expense serves a bona‑fide corporate purpose. This reality can shape how expatriates plan their living arrangements and negotiate their compensation packages.
Overall, a representative office offers a low‑risk entry point for foreign businesses, but the compliance environment is anything but simple. Companies must stay vigilant about reporting deadlines, maintain accurate labor and tax records, and ensure that all expenses are properly documented to avoid turning a seemingly harmless cost into a personal tax liability for the chief representative.
Compliance is essential.
