In the context of increasingly stringent tax administration, the trading of invoices and the use of fraudulent documents for accounting purposes continue to occur in various enterprises. Such conduct is commonly intended to legitimize expenses, reduce tax liabilities, and poses significant legal risks relating to taxation and accounting compliance.

I. The current situation of invoice trading for the purpose of legitimizing expenses

In current business practice, the trading of invoices and the use of fraudulent documents for accounting purposes remain prevalent to varying degrees, particularly among small and medium-sized enterprises or entities with inadequate internal control systems. The primary purpose of such conduct is to legitimize input expenses, reduce taxable profits, thereby lowering corporate income tax obligations, or to present a more favorable financial position in financial statements. In some cases, enterprises utilize documents unsupported by actual transactions or invoices issued by “shell companies” to justify fund movements.

Although tax authorities and competent State agencies have strengthened the application of technology, data reconciliation, inspections, and audits, these practices have become increasingly sophisticated through methods such as splitting transactions, using multiple intermediary entities, or legitimizing transactions through complex corporate structures.

Such situations not only cause losses to the State budget but also expose enterprises to substantial legal risks, including tax reassessments, administrative sanctions, and even criminal prosecution where organized fraudulent activities are identified.

II. Concept of using fraudulent documents for accounting purposes

1. What constitutes the use of fraudulent documents for accounting purposes?

The use of fraudulent documents for accounting purposes refers to an act whereby an enterprise or accounting personnel utilize illegal, forged, or fictitious documents that do not reflect actual economic transactions for recording in accounting books and records.

Under accounting regulations, documents may only be used for accounting purposes when they accurately reflect actual economic transactions and satisfy the requirements of legality, validity, and reasonableness. However, if fraudulent documents are used, these requirements are not met, resulting in inaccurate recognition of revenue, expenses, or tax obligations.

Such conduct is typically intended to legitimize expenses, reduce taxable income, or manipulate business performance contrary to reality, and may lead to serious legal consequences under accounting and tax legislation.

2. What types of documents are commonly forged for accounting purposes?

  • The content of the documents is inconsistent with the enterprise’s business operations or registered business lines;
  • Inconsistencies in invoice or contract information (incorrect tax identification numbers, addresses, signatures, seals, issuance dates, etc.);
  • Absence of actual payment records or failure of large-value transactions to be conducted through banking channels;

IV. Questions regarding the use of fraudulent supporting documents for accounting purposes

1. Is the use of purchased invoices considered the use of fraudulent documents?

The use of purchased invoices by an enterprise is not automatically deemed the use of fraudulent documents for accounting purposes. A purchased invoice is only considered a fraudulent document if it does not reflect an actual economic transaction or is issued in violation of legal regulations.

Specifically, a purchased invoice may be regarded as a fraudulent document in the following circumstances:

  • The sale and purchase transaction did not actually occur;
  • The invoice was issued by a “shell company” that does not conduct actual business operations;
  • Goods or services were never supplied, yet an invoice was issued to record expenses;
  • Information on the invoice was falsified for the purpose of legitimizing expenses.

Conversely, if a purchased invoice accurately reflects an actual transaction and is supported by complete documents, valid payment records, and proper acceptance documents, it remains a lawful accounting document in accordance with accounting and tax regulations.

2. Can an accountant be held liable for using fraudulent documents under the instruction of a superior?

An accountant may still take legal responsibility for using fraudulent documents for accounting purposes, even if such actions were carried out under the instruction of a superior. Specifically:

  • Regarding administrative sanctions, Clause 3, Article 8 of Decree No. 41/2018/ND-CP provides that forging or making false declarations in accounting documents, where the conduct does not yet warrant criminal prosecution, is subject to a fine ranging from 20,000,000 VND to 30,000,000 VND. In addition, Clause 3 of the same Article stipulates that any person who agrees with or compels another person to forge or falsify accounting documents shall be subject to equivalent sanctions. 
  • If the conduct results in serious consequences, the accountant may be subject to criminal prosecution under Article 221 of the Criminal Code 2015 (as supplemented by Clause 1 and Clause 3, Article 2 of the Law Amending the Criminal Code 2017) concerning the offense of violating accounting regulations causing serious consequences.

However, when determining liability, competent authorities will also consider factors such as:

  • The accountant’s role and level of involvement;
  • Whether the accountant was coerced into committing the act;
  • Whether the accountant was fully aware of the fraudulent nature of the documents.

3. Does the use of fraudulent documents affect financial statements?

The use of fraudulent documents for accounting purposes directly and significantly affects the accuracy and reliability of financial statements. Specifically, it may:

  • Distort revenue, expenses, and profits, causing business results to fail to reflect actual performance;
  • Affect the balance sheet through the inaccurate recognition of assets, liabilities, or equity;
  • Reduce the transparency and credibility of financial statements, creating risks during audits or tax inspections;
  • Result in accounting adjustments, tax reassessments, and administrative sanctions if discovered by competent authorities.

Furthermore, where the use of fraudulent documents is systematic in nature or causes serious consequences, the enterprise may also face legal risks under accounting and tax regulations, including potential criminal liability.

4. How can the legality of invoices and accounting documents be verified?

To mitigate the risks associated with the use of fraudulent documents, enterprises should verify the legality of invoices and accounting documents based on legal requirements and actual transaction records, including:

  • Verifying the seller’s legal information, including tax identification number, enterprise name, and operational status on the tax authority’s system;
  • Comparing invoice details with the actual transaction to confirm that goods or services were genuinely provided and supported by contracts and acceptance records;
  • Verifying the validity of electronic invoices through the tax authority’s e-invoice portal to ensure that the invoice was lawfully issued;
  • Reviewing payment documents, with priority given to bank transfers for high-value transactions to ensure transparency of cash flows;
  • Examining the consistency of the supporting documents, including invoices, contracts, goods receipt and delivery notes, and handover records, to ensure consistency in content, timing, and value;
  • Assessing risk indicators relating to business partners, such as unusually newly established enterprises, entities lacking actual business operations, or those with a history of invoice-related violations.
