Decree No. 252/2026/ND-CP, which provides detailed guidance for the implementation of the Law on Tax Administration, goes beyond introducing procedural updates. It reflects Vietnam’s continued efforts to modernise its tax administration through digitalisation, greater data connectivity, compliance-based administration and a more comprehensive regulatory framework for emerging business models.
For businesses, this is more than a routine legal update. It signals a gradual shift in the way tax authorities administer the tax system – and, consequently, how businesses should approach tax compliance. Meeting filing obligations alone is no longer sufficient. Businesses are increasingly expected to maintain reliable tax data, strengthen internal governance and proactively manage tax risks.
Against this backdrop, Decree No. 252/2026/ND-CP introduces several noteworthy changes that may have practical implications for businesses operating in Vietnam. Below are six key developments that deserve particular attention.
1. Strong Tax Compliance May Unlock Preferential Administrative Treatment (Article 48)
One of the Decree’s most significant developments is the introduction of a preferential regime for eligible taxpayers.
Under Article 48, taxpayers that satisfy the prescribed conditions may benefit from a number of administrative facilitation measures, including:
- Pre-populated information on tax returns using shared government databases;
- A refund-first, audit-later approach for eligible tax refund applications;
- Exclusion from on-site tax inspection plans for tax periods or matters assessed as presenting low tax risk; and
- Priority treatment in certain tax administrative procedures, including Advance Pricing Agreements (APA) and the Mutual Agreement Procedure (MAP).
This represents an important development in Vietnam’s tax administration framework. Rather than focusing solely on enforcement, the Decree also encourages voluntary compliance by providing administrative incentives for taxpayers with a strong compliance record.
Key Takeaways for Businesses
- Assess your current level of tax compliance against the evolving regulatory expectations.
- Review whether tax records, supporting documentation and tax data are complete, accurate and consistent.
- Strengthen internal tax governance to improve long-term compliance and position your business to benefit from preferential administrative treatment where applicable.
2. The Window for Correcting Tax Errors Has Been Shortened to Five Years (Article 12)
Another significant change is the reduction of the statutory period for submitting supplementary tax declarations. Under the Decree, taxpayers may amend previously filed tax returns within five years from the statutory filing deadline, compared with ten years under the previous regulations.
After the five-year period expires, taxpayers will no longer be able to correct tax declarations through the standard supplementary filing mechanism and must instead submit an explanation dossier for review and processing by the tax authority in accordance with the regulations.
This change increases the importance of timely tax reviews, particularly for businesses with complex transactions or historical tax positions that have not been reviewed on a regular basis.
Key Takeaways for Businesses
- Perform periodic Tax Health Checks rather than waiting until a tax audit or inspection takes place.
- Identify and rectify tax errors within the five-year statutory period wherever possible.
- Establish an annual tax review process to monitor potential tax exposures before they become more difficult to address.
3. Data Integrity Will Become Central to Tax Administration (Articles 49, 51 and 58)
Decree No. 252/2026/ND-CP establishes the legal framework for developing an integrated Tax Administration Information System, enabling greater digitalisation, inter-agency data sharing and the broader application of technology in tax administration.
The Decree also provides for enhanced data connectivity between the tax authorities and other government agencies, including the State Bank of Vietnam, the Ministry of Public Security and the Ministry of Industry and Trade, among others, in accordance with the applicable legal framework.
As tax authorities gain access to a broader range of digital information, data consistency will become increasingly important. Discrepancies between accounting records, e-invoices, financial statements and tax filings are likely to receive greater scrutiny through automated data matching and risk assessment.
Key Takeaways for Businesses
- Review the consistency of data across accounting records, e-invoices, financial statements and tax filings.
- Strengthen data governance and internal controls to improve data quality and reliability.
- Consider whether existing ERP systems and accounting processes are capable of supporting increasingly data-driven tax administration.
4. Cross-border Profit Repatriation Will Require Closer Tax Planning (Article 27)
For foreign-invested enterprises (FIEs), the Decree formally incorporates the conditions for overseas profit remittance into the regulatory framework.
In particular:
- An enterprise must have no outstanding tax liabilities at the time profits are remitted overseas; and
- Upon the termination of an investment project or business operations, all tax obligations must be fulfilled, including taxes that have not yet fallen due in accordance with the Decree.
These requirements reinforce the close relationship between tax compliance and cross-border cash flow management. Profit distribution decisions should therefore be considered alongside the enterprise’s overall tax position rather than as a standalone treasury matter.
Key Takeaways for Businesses
- Review tax compliance status before planning annual profit remittances, restructuring exercises or investment exits.
- Incorporate tax compliance reviews into cross-border cash flow planning.
- Ensure all tax obligations are identified and addressed well in advance of any planned profit remittance.
5. Tax Non-compliance May Have Direct Consequences for Business Owners and Executives (Article 28)
Decree No. 252/2026/ND-CP further clarifies the rules on temporary exit suspension for individuals associated with enterprises that are subject to tax enforcement measures.
Under Article 28, temporary exit suspension may be applied where an enterprise has outstanding tax liabilities of VND 500 million or more that remain overdue for more than 120 days. The scope of application extends beyond the legal representative to include the beneficial owner of the enterprise, where applicable under the Decree.
At the same time, the Decree provides a mechanism for lifting the temporary exit suspension immediately once the taxpayer satisfies the prescribed conditions and rectifies the overdue tax position in accordance with the regulations.
This development highlights that tax compliance is no longer solely a corporate matter. In certain circumstances, unresolved tax liabilities may have direct implications for individuals responsible for the business.
Key Takeaways for Businesses
- Monitor outstanding tax liabilities on an ongoing basis rather than only at year-end.
- Establish internal procedures to address overdue tax obligations promptly.
- Businesses with foreign ownership or complex ownership structures should assess the potential implications for legal representatives and beneficial owners.
6. New Rules Affect Both E-commerce Tax Compliance and Businesses under Invoice Enforcement (Articles 43 and 69)
The Decree introduces clearer rules for tax administration in the digital economy while also providing a practical mechanism for businesses facing invoice enforcement measures.
For e-commerce, operators of online marketplace platforms that facilitate both ordering and payment are responsible for withholding, declaring and remitting taxes on behalf of household businesses, individual business operators and overseas suppliers in accordance with the applicable regulations.
Another noteworthy development is found in Article 69, which provides a practical solution for businesses that are subject to enforcement measures suspending the use of invoices.
Where a business needs to issue an invoice on a transaction-by-transaction basis, it may do so by paying at least 18% of the invoice’s total payment value into the state budget. In such cases, the tax authority will also temporarily suspend bank account enforcement measures (for an amount corresponding to the total payment value of the invoice used) for up to 10 working days in accordance with the Decree.
This mechanism enables businesses to continue issuing invoices, maintain commercial transactions and generate cash flow while progressively addressing their outstanding tax obligations.
Key Takeaways for Businesses
- Businesses operating through e-commerce platforms should establish reconciliation procedures between sales data and taxes withheld and remitted by the platform.
- Businesses facing cash flow constraints should familiarise themselves with the relief mechanisms available under the Decree to minimise disruptions to normal business operations.
Conclusion
Decree No. 252/2026/ND-CP represents more than an update to Vietnam’s tax administration regulations. It reflects the country’s continued move towards a tax administration framework that is increasingly digital, data-driven and compliance-oriented.
Beyond introducing new procedural requirements, the Decree reinforces a broader policy direction: encouraging voluntary compliance, strengthening the use of technology and data in tax administration, and enhancing oversight of emerging business models and cross-border activities.
As Vietnam’s tax administration continues to evolve, tax compliance should no longer be viewed solely as a statutory obligation. Increasingly, it has become an integral part of corporate governance, operational resilience and sustainable business growth. Businesses that prepare early will be better positioned to navigate the changing regulatory landscape with confidence.
