Effective date: 01 June 2025

Vietnam’s tax system has undergone a profound transformation over the past decade, driven by digitalisation, rising cross-border transactions, and the rapid expansion of platform-based business models. In this evolving environment, invoices are no longer merely accounting documents; they are now critical data instruments that enable tax authorities to monitor economic activity in real time, assess compliance risks, and align taxation with actual value creation.

Against this backdrop, Decree 70/2025/NĐ-CP (“Decree 70”), effective from 01 June 2025, represents an important recalibration of Vietnam’s electronic invoicing framework. Rather than introducing an entirely new system, the decree refines and strengthens existing rules to better reflect commercial realities particularly those arising from e-commerce, digital services, high-volume transactions, and export-oriented activities.

For businesses operating in Vietnam, including foreign-invested enterprises (FIEs) and offshore service providers, Decree 70 sends a clear signal: invoicing compliance is becoming more precise, more data-driven, and more closely integrated with tax administration and customs systems. Understanding the intent and implications of these changes is essential not only to avoid compliance risks, but also to operate efficiently in Vietnam’s increasingly digital tax environment.

A Broader Invoice Framework in a Digital Economy

One of the most notable developments under Decree 70 is the expansion of the scope of electronic invoicing to explicitly include foreign suppliers without a permanent establishment in Vietnam. This provision directly addresses a long-standing regulatory gap in the taxation of cross-border digital services.

Foreign suppliers without permanent establishment

Under the revised scope of application, foreign suppliers engaged in e-commerce, digital platform-based business, or other cross-border services may voluntarily register to use electronic invoices, including VAT invoices, in Vietnam.

This change reflects a broader policy shift. As Vietnam’s economy becomes more digitally connected, a growing share of consumption, ranging from advertising services and cloud computing to online subscriptions and platform-based services, is supplied by offshore entities. While tax registration and declaration mechanisms for such suppliers have existed, the lack of a clear invoicing framework has created practical challenges for both suppliers and Vietnamese customers.

By allowing foreign suppliers to issue electronic invoices within Vietnam’s tax system, Decree 70 improves transaction transparency and documentation quality. For Vietnamese enterprises purchasing services from overseas providers, this enhances the reliability of invoices used for tax declaration, expense recognition, and internal compliance. For foreign suppliers, while registration remains voluntary, commercial pressure from customers may increasingly make electronic invoicing a practical necessity rather than a mere option.

Electronic Commercial Invoices and Export Activities

Export-oriented businesses play a central role in Vietnam’s economic model, and Decree 70 introduces targeted measures to support and regulate invoicing practices in this sector.

Formal recognition of electronic commercial invoices

Decree 70 clarifies that organisations, businesses, and individuals engaged in exporting goods or providing services abroad may issue electronic commercial invoices, provided they satisfy the technical requirements for electronic transmission of invoice data to the tax authority.

This provision addresses inconsistencies that exporters have faced in practice, particularly when reconciling commercial invoices, VAT invoices, and customs documentation. By formally recognising electronic commercial invoices within the invoicing framework, the decree aligns tax documentation more closely with Vietnam’s increasingly digitised customs clearance system.

For exporters handling high transaction volumes or operating across multiple markets, this change offers the potential for more streamlined documentation processes. At the same time, it raises expectations around data accuracy, system integration, and timely transmission of invoice information to tax authorities.

Clarifying the Timing of Invoice Issuance

The timing of invoice issuance has historically been one of the most common sources of tax risk for businesses in Vietnam. Decree 70 introduces several targeted clarifications designed to reduce ambiguity while maintaining alignment with commercial realities.

Exported goods, including processing for export

For exported goods, including goods processed for export, the decree specifies that the invoice issuance time is determined by the seller’s issuance of an electronic commercial invoice, VAT invoice, or sales invoice. Crucially, the invoice must be issued no later than the next working day after the goods are cleared through customs.

This rule creates a clear and enforceable link between customs clearance and tax invoicing, reducing uncertainty and limiting opportunities for delayed or inconsistent invoice issuance.

Services provided to foreign organisations and individuals

For services provided to foreign organisations or individuals, Decree 70 aligns the invoice issuance timing with that applicable to domestic services. The invoice must be issued at the time of service completion, regardless of whether payment has been received.

This clarification marks an important shift in practice. Previously, some businesses delayed invoicing until payment was received, particularly for cross-border services. Under the new framework, service completion becomes the decisive factor, reinforcing accrual-based taxation principles and improving consistency in tax reporting.

Transactions requiring data reconciliation

Recognising the operational complexity of certain industries, Decree 70 introduces specific rules for transactions involving large volumes and frequent transactions that require data reconciliation between the parties.

In such cases, invoice issuance may be deferred until reconciliation is completed. However, this flexibility is subject to strict limits. The invoice must be issued no later than either:

• The 7th day of the month following the month in which the transaction occurred; or
•  Seven days from the end of the agreed reconciliation period.

This exception applies only to specific sectors, including e-commerce services, banking services (excluding lending activities), securities services, international money transfers, electronic lottery, road toll collection, railway support services, and other cases guided by the Ministry of Finance. Outside these narrowly defined cases, businesses remain subject to standard invoice issuance timing rules.

Strengthening Invoice Content and Data Integrity

Beyond timing, Decree 70 places greater emphasis on the content and quality of invoice data, reflecting the tax authority’s increasing reliance on electronic invoices as a primary source of compliance information.

Expanded buyer identification requirements

Invoices must now include, in addition to the buyer’s name, address, and tax code:

• The buyer’s personal identification number (for individuals); or
• The identification number of the budget-related entity (for organisations).

This enhanced identification requirement improves traceability and supports data matching across government systems.

Industry-specific information

Certain sectors are subject to additional content requirements. For example, food and beverage businesses must specify food and beverage items, while transportation service providers must include vehicle license plate numbers and route information. These requirements reflect a risk-based approach, targeting sectors where transaction verification and service delivery details are particularly relevant for tax administration.

Digital signing and transmission obligations

Where the time of invoice creation differs from the time of digital signing, the invoice must be digitally signed and transmitted to the tax authority no later than the following day. The decree also reiterates the distinction between invoices issued with tax authority codes and those issued without, clarifying the corresponding transmission obligations.

Importantly, the decree maintains clear principles regarding tax declaration timing: sellers declare tax based on the invoice issuance date, while buyers declare tax upon receipt of a valid and compliant invoice.

A New Approach to Invoice Errors: From Cancellation to Adjustment

Another significant shift under Decree 70 is the removal of the concept of invoice cancellation for incorrectly issued electronic invoices.

Adjustment and replacement as the new standard

Under the revised framework, errors must be corrected through invoice adjustment or replacement. Before issuing an adjusted or replacement invoice involving enterprise buyers, the seller and buyer must enter into a written agreement clearly identifying the inaccuracies.

The decree also introduces flexibility by allowing a single adjustment or replacement invoice to cover multiple incorrect invoices issued in the same month to the same buyer, provided a detailed list is attached. This change reduces administrative burden while preserving transparency and auditability.

Clear guidance is also provided on the timing of tax declaration for adjusted and supplementary invoices, reducing uncertainty for both sellers and buyers.

Implications for Businesses Operating in Vietnam

The changes introduced by Decree 70 have practical implications across a wide range of business models.

For foreign suppliers without a permanent establishment, voluntary registration for electronic invoicing may increasingly become a commercial expectation, particularly when dealing with corporate customers in Vietnam. While registration enhances transparency, it also brings greater visibility to tax authorities, underscoring the need for robust compliance systems.

Exporters must ensure that invoicing processes are tightly aligned with customs clearance timelines and that electronic commercial invoices meet all transmission requirements. Delays or inconsistencies may not only trigger penalties but also complicate VAT refund claims.

Service providers, especially those engaged in cross-border or platform-based activities, should reassess how service completion is defined and tracked. In many cases, this will require closer coordination between operational teams and accounting functions to ensure invoices are issued at the correct time.

Accounting and tax compliance teams should expect higher expectations around invoice data quality. ERP systems, invoicing software, and internal controls may need to be updated to capture additional information and support revised adjustment procedures.

Looking Ahead

Decree 70/2025/NĐ-CP reinforces Vietnam’s commitment to building a modern, digital, and data-driven tax administration system. While the decree introduces more detailed rules and higher compliance expectations, it also brings greater clarity and consistency particularly in areas that have historically posed challenges for businesses.

For enterprises registered in Vietnam, including foreign-invested companies and offshore service providers, early alignment with the new invoicing requirements will be critical. Those that proactively adapt their systems and processes will not only reduce compliance risk but also position themselves to operate more efficiently in Vietnam’s increasingly sophisticated tax environment.

As electronic invoicing continues to evolve, Decree 70 serves as a reminder that compliance and strategy are no longer separate considerations. In Vietnam’s digital tax landscape, they are increasingly one and the same
