Official Letter No. 4937/CT-NVT dated July 17, 2026, issued by the Tax Department, provides detailed guidance on tax registration procedures under Decree 252/2026/ND-CP and Circular 90/2026/TT-BTC. Branches and Representative Offices of foreign companies in Vietnam should note the following:
1. Key procedural deadlines:
- New registration / Information changes / Tax code termination: All filings must be submitted within 10 working days.
- Temporary suspension of operations: Notification must be submitted at least 1 working day in advance (each suspension period not exceeding 12 months).
2. Five-year record retention obligation:
Branches/Representative Offices must retain all records and documents relating to beneficial ownership information for at least 5 years from the end of the calendar year or the year operations cease.
3. Tax authorities tightening oversight from July 2026:
Declared data will be cross-checked against the national database and centrally managed on the TMS system on a periodic basis, before the 20th of each month.
👉 Recommendation for businesses: Proactively review your Branch’s/Representative Office’s tax registration information to be ready to respond to or supplement documentation upon request from the tax authorities, avoiding a reactive position during operations!
