Vietnam Tax Compliance for Overseas Digital Service Providers

Vietnam maintains a rigorous tax management system for non-resident e-commerce and digital platform providers. Under current regulations, especially Circular No. 80/2021/TT-BTC, overseas suppliers without a permanent establishment in Vietnam are permitted to directly fulfill their tax obligations without the involvement of Vietnamese customers.

For overseas suppliers generating income in Vietnam through e-commerce and digital platforms, a thorough understanding of these requirements, ranging from electronic registration to applicable withholding mechanisms, is essential to ensure compliance, mitigate the risk of administrative penalties, and proactively manage their tax obligations in Vietnam.

Key compliance entities

The regulations identify four primary stakeholders in the digital tax ecosystem:

• Overseas suppliers: Non-resident suppliers providing digital services or e-commerce goods to Vietnamese organizations and individuals.
• Vietnamese buyers: The recipients of goods or services (both B2B and B2C).
• Authorized tax agents: Vietnam-based entities or tax agents empowered by the overseas suppliers to handle tax procedures locally.
• Financial intermediaries: Commercial banks and payment service providers responsible for withholding taxes in specific scenarios.

Registration and electronic tax transactions

To streamline compliance, the General Department of Taxation (GDT) has centralized procedures through a dedicated electronic portal.

• Initial registration: Eligible overseas suppliers (OS) must register for an electronic tax transaction account and a Tax Identification Number (TIN). The process requires a valid email address for all official correspondence.
• Digital authentication: All transactions, including registration and filing, are authenticated via a transaction confirmation code issued by the GDT portal to the registered email address.

Online registration procedures for overseas suppliers in Vietnam

Overseas suppliers seeking to enter or maintain a presence in the Vietnamese digital market must follow a specific electronic registration workflow. This process is centralized through the GDT specialized portal, which facilitates cross-border compliance without a physical presence.

Mandatory electronic tax transaction registration

To initiate tax activities in Vietnam, overseas suppliers must register for electronic transactions concurrently with their initial tax registration. To streamline compliance, the GDT has centralized procedures through a dedicated electronic portal.

This digital-first approach requires the OS to meet two fundamental technical criteria:

• Reliable Internet Access: The ability to access and operate via the GDT’s e-portal system.
• Official Email Account: A designated, permanent email address used exclusively for official correspondence, notifications, and transaction confirmations from the Vietnamese tax authorities. This email address may be updated when necessary.

Issuance of Tax Identification Numbers

The TIN serves as the primary identifier for all regulatory filings in Vietnam. Whether an overseas supplier registers directly or through an authorized local representative, the registration must be completed using Form No. 01/NCCNN in accordance with the guidelines prescribed under Circular 80.

Once the initial registration is successfully processed via the portal, the GDT will transmit the account credentials and the assigned TIN directly to the supplier’s registered email address. This account becomes the gateway for all subsequent filing and payment activities.

Direct tax declaration and payment by overseas suppliers

Protocols for direct tax registration and data updates

Overseas suppliers are responsible for maintaining accurate registration data. The regulatory framework specifies the exact forms required for both initial entry and subsequent changes:

• First-time registration: Suppliers must submit Form No. 01/NCCNN (as provided in Appendix I of Circular 80) via the e-portal.
• Modifying information: Any changes to the supplier’s corporate details or contact information must be updated using Form No. 01-1/NCCNN.
• Authentication requirements: To ensure security and data integrity, overseas suppliers must use a Transaction Verification Code issued by the tax authorities via the e-portal to authenticate each registration or amendment filing.

Tax declaration and payment obligations

Overseas suppliers must:

• Register and file tax declarations electronically via the GDT’s e-portal.
• Use a transaction authentication code issued by the managing tax authority.
• Submit electronic tax returns to their directly supervising tax authority.
• Make payments in accordance with the guidance issued by the tax authority after successful submission of the tax returns.

Key compliance requirements include:

• Filing frequency: Quarterly
• Tax return form: Form No. 02/NCCNN (issued under Appendix I of Circular 80)
• Tax calculation method:
  • Value-added tax (VAT) and corporate income tax (CIT) are calculated using a deemed percentage on gross revenue.
  • Taxable revenue for both VAT and CIT purposes is the total revenue received by the overseas supplier.

Applicable percentage rates are determined in accordance with the prevailing VAT and CIT regulations. For example, the applicable tax rate for digital services are 10 percent VAT and 5 percent CIT.

If errors are identified after submission, overseas suppliers must file an adjusted declaration using Form No. 02/NCCNN.

To facilitate overseas suppliers in understanding and independently fulfilling their tax obligations, the tax forms are provided in bilingual format, and tax payments may be made in multiple currencies, not limited to VND.

Determination of Vietnam-sourced revenue

To determine whether a transaction arises in Vietnam for tax declaration purposes, overseas suppliers must rely on specified identification criteria.

Rules for transaction determination

To confirm that a transaction arises in Vietnam:

1. The overseas supplier must use two non-contradictory data points, including:
   • One payment-related indicator; and
   • One residency or access-related indicator.
2. If payment information is unavailable or inconsistent, the supplier may rely on:
   • One residency indicator; and
   • One access indicator, provided they are not contradictory.

Authentication, payment code, and record-keeping

• Overseas suppliers must use the electronic transaction authentication code issued by the tax authority when filing or adjusting declarations.
• After submission, the tax authority will issue a state budget payment identification number to facilitate tax remittance.
• Suppliers are responsible for retaining all information used to determine Vietnam-sourced transactions for inspection and audit purposes, in accordance with the Law on Tax Administration.

Double taxation agreements (DTAs)

Where an overseas supplier is resident in a jurisdiction that has signed a tax treaty with Vietnam, procedures for tax exemption or reduction shall be carried out in accordance with Article 62 of the Circular 80 and the applicable Double Taxation Agreement.

Please note that treaty relief is applicable only to the CIT portion.

Authorization and representation

Overseas suppliers may choose to authorize a local tax agent to manage their filings.

• Notification: If switching from direct filing to an agent, the OS must notify the TD at least five working days before the contract becomes effective.
• Compliance Responsibility: The authorized representative is liable for the accuracy of filings based on the documentation provided by the OS.

Enforcement: Local withholding mechanisms

Where an overseas supplier fails to register or pay tax, the TD shifts the compliance burden to local parties.

B2B transactions

Vietnamese organizations purchasing from non-compliant OS must withhold and remit the tax themselves under the prevailing tax regulations .

B2C transactions (Commercial bank obligations)

For individual buyers, commercial banks and payment intermediaries are responsible for:

• Withholding and remittance: Remitting tax by the 20th of each month for suppliers on the GDT’s “Non-Compliant” list.
• Tracking and reporting: If withholding is technically unfeasible (e.g., certain card transactions), banks must report transaction volumes to the GDT by the 10th of each month.

Key takeaways for businesses

Overseas suppliers deriving income from e-commerce and digital platforms in Vietnam should consider leveraging the prevailing regulatory framework, which permits direct tax registration, declaration, and payment in Vietnam. This mechanism enables overseas suppliers to independently manage and fulfill their tax obligations without reliance on Vietnamese customers or intermediary parties.

Adopting this approach strengthens overall tax governance, enhances compliance oversight, mitigates exposure to risks arising from potential non-compliance by Vietnamese counterparties, and minimizes the need for customer involvement in the event of future tax inspections or audits.
