Tax authorities defeated in court over 12 billion VND penalty dispute regarding alleged illegal invoices

A protracted legal battle between a corporate entity and tax authorities in Ho Chi Minh City has culminated in a significant judicial ruling that highlights the stringent procedural requirements for state tax audits. The High People’s Court of Ho Chi Minh City recently upheld an appellate decision to annul a tax penalty and collection order totaling nearly 12 billion VND (approximately 480,000 USD) against a firm referred to as Company S. The court’s decision centered not on the substantive merits of the tax evasion claims, but on fundamental procedural flaws and the lack of proper credentials among the personnel conducting the tax audit.

The Origin of the Dispute

The conflict originated from a tax audit conducted between September 6, 2022, and October 10, 2022, covering the fiscal years 2011 through 2019. During this period, tax officials from the Ho Chi Minh City Tax Department scrutinized the financial records of Company S.

The dispute emerged when the tax authority flagged five specific invoices issued in 2019 by two separate entities, identified as Company T and Company F. The tax authorities alleged that these invoices were "illegal" because the issuing companies were no longer operating at their registered addresses at the time of issuance. Furthermore, the tax office noted that the tax declarations for these firms showed zero goods and services traded during the period in question, and both companies listed only a single individual in their respective personal income tax filings.

Based on these findings, the Ho Chi Minh City Tax Department issued a decision on November 1, 2022, mandating a total recovery and penalty of nearly 12 billion VND. This sum included:

• Approximately 5.6 billion VND in penalties for using illegal invoices to reduce corporate income tax (CIT) obligations.
• 5.9 million VND in penalties for incorrect declarations leading to tax underpayment.
• 5.9 billion VND in tax arrears (193.9 million VND in VAT and 5.7 billion VND in CIT).
• Additional late payment interest totaling 160 million VND and a reduction of 8.7 million VND in VAT credits for future periods.

Company S’s Defense and Initial Litigation

Company S contested the tax authority’s findings, arguing that the reduction of their cost-of-goods-sold (COGS) was inconsistent with both reality and legal regulations. The company asserted that the transactions were legitimate and backed by bank records. Specifically, the company maintained that payments for the goods in question were made directly from their bank account to the sellers, providing a clear audit trail of the funds.

Beyond the substance of the invoices, Company S raised a procedural challenge: they questioned the authority and professional standing of the members of the tax audit team. The company argued that the audit team failed to provide documentation verifying their status as qualified "tax inspectors" at the time of the audit. Consequently, Company S filed a lawsuit in the People’s Court of Ho Chi Minh City, requesting the total cancellation of the tax department’s administrative penalty decision.

The Judicial Process and Court Findings

At the first instance, the People’s Court of Ho Chi Minh City ruled in favor of Company S, finding that the tax audit was conducted improperly. The Ho Chi Minh City Tax Department appealed this decision, and the Prosecutor’s Office of the High People’s Court of Ho Chi Minh City similarly filed a recommendation to overturn the lower court’s ruling, arguing that the tax department’s actions were consistent with administrative necessity.

However, during the appellate hearing, the High People’s Court of Ho Chi Minh City conducted a detailed review of the audit team’s credentials. The tax department admitted that at the time of the audit, the personnel involved were not classified as "tax inspectors." Due to internal industry restructurings, all civil servants previously holding the "tax inspector" rank had been transitioned to "tax examiner" or "specialist" roles.

The court reached a definitive conclusion: the administrative proceedings were void. The judges stated that the lack of properly credentialed inspectors meant the audit report lacked legal validity. Furthermore, the court emphasized that administrative agencies cannot cite "staffing shortages" or "internal restructuring" as an excuse to bypass mandatory legal procedures. If a tax audit is not conducted by authorized individuals under the law, any resulting penalties and administrative decisions are inherently defective.

Regarding the allegations of tax evasion, the court noted that if the tax authority truly believed the transactions were fraudulent or constituted tax evasion, they were obligated to transfer the case files to investigative police agencies. By opting to issue an administrative penalty decision instead of pursuing a criminal investigation, the tax department had followed an incorrect procedural path, further invalidating the 12 billion VND penalty.

Broader Implications for Tax Administration

This ruling serves as a cautionary tale for state agencies regarding the necessity of strict procedural compliance. For businesses in Vietnam, the case underscores the importance of maintaining robust documentation—such as bank-to-bank payment records—to verify the legitimacy of transactions.

Legal experts point out that while tax authorities have broad powers to investigate and collect arrears, those powers are strictly delimited by the Law on Tax Administration. The court’s decision effectively reminds regulators that "the end does not justify the means." Even if the tax authority suspects illicit activity, they must act within the established legal framework regarding the qualifications of their auditors and the correct sequence of enforcement.

For the Ho Chi Minh City Tax Department, the verdict necessitates a review of their internal audit protocols. The case highlights that administrative actions, when challenged, are subject to the same level of scrutiny as the business practices they aim to regulate.

Chronology of the Dispute

• 2011–2019: Period covered by the tax audit of Company S.
• 2019: The five disputed invoices were issued by Company T and Company F.
• Sept 6 – Oct 10, 2022: The Ho Chi Minh City Tax Department conducts the audit.
• Nov 1, 2022: The Tax Department issues the decision to penalize and collect 12 billion VND.
• Late 2022 – Early 2025: Company S initiates litigation, leading to the first-instance trial.
• Sept 4, 2025: The High People’s Court of Ho Chi Minh City issues the final appellate judgment (Judgment No. 132/2025/HC-PT), upholding the cancellation of the tax penalties.

Analysis of the Verdict’s Impact

The outcome of this case is significant for several reasons. First, it reinforces the principle that procedural errors in administrative law can be just as fatal to a government agency’s case as substantive errors. The court’s refusal to accept "administrative reality" (such as the shifting of job titles within the tax office) as a justification for non-compliance with the Tax Law is a strong signal of judicial independence.

Second, it provides a degree of protection for taxpayers against potentially arbitrary or improperly conducted audits. Businesses often feel vulnerable during tax inspections; this ruling establishes a precedent that taxpayers have the right to demand proof of authority and to challenge the legality of the audit process itself.

Third, it clarifies the boundary between administrative tax recovery and criminal tax evasion. The court’s statement—that if evidence suggests criminal fraud, the tax authority should defer to the police—prevents tax agencies from unilaterally acting as both investigator and judge in complex cases involving potentially fraudulent invoice schemes.

As of the conclusion of the case, the 12 billion VND in penalties remains nullified. The Ho Chi Minh City Tax Department is expected to refine its training and credentialing processes to ensure that future audit teams meet the strict statutory requirements required to uphold such significant financial assessments. This case remains a vital reference for legal practitioners and corporate tax departments navigating the complexities of tax enforcement in Vietnam.
