VAT registration in Vietnam is crucial for foreign companies to ensure compliance with Vietnamese tax laws, avoid penalties, and conduct business smoothly in the Vietnamese market. This guide explains the GST/VAT/HST/CST registration in Vietnam, and procedures for foreign companies seeking VAT registration in Vietnam.

Why Non-Resident Firms Must Register for VAT/GST in Vietnam

Non-compliance with GST/VAT/HST/CST registration in Vietnam can result in severe penalties, including fines up to VND 25 million for late filing, blocked marketplace access, and customs holds on imports. Foreign suppliers who fail to register may face administrative violations ranging from VND 2-25 million, depending on the delay period, plus interest charges of 0.03% per day on unpaid VAT amounts. 

The Vietnamese government has actively enforced these regulations; for instance, in December 2024, the trade ministry ordered Chinese online retailer Temu to suspend its operations in Vietnam after missing a registration deadline. Such enforcement underscores the importance of timely VAT/GST registration to maintain business continuity and compliance.

When Does a Foreign Business Need to Register? Key Triggers

Foreign companies must register for VAT/GST in Vietnam when their activities establish a taxable presence or involve specific transactions that trigger VAT obligations. Key scenarios include:

  • Digital services and e-commerce: Foreign suppliers providing digital services, e-commerce activities, or operating digital platforms to Vietnamese consumers must register, regardless of physical presence
  • Import and local sales: Companies importing goods into Vietnam or establishing local inventory/warehouses trigger immediate registration requirements
  • Marketplace facilitation: Businesses operating through Vietnamese e-commerce platforms or facilitating transactions for other sellers require registration
  • Trade shows and temporary activities: Participating in Vietnamese trade exhibitions or conducting temporary business activities may require registration

Country-Specific Examples:

  • UK digital services company: A British software provider offering SaaS solutions to Vietnamese businesses must register for VAT upon first sale, as the nil threshold means immediate registration is required.
  • Chinese e-commerce seller: An online retailer from China selling directly to Vietnamese consumers through local platforms must register and collect 10% VAT starting July 2025.

Understanding these triggers helps foreign businesses comply with Vietnamese tax obligations before commencing operations.

Registration Thresholds & Nexus Tests
