Auditing foreign direct investment (FDI) enterprises plays a crucial role as a growth driver for the Vietnamese economy, with registered capital reaching tens of billions of USD each year. To ensure transparency and protect the rights of investors as well as the State, Vietnamese law has enacted strict regulations on controlling financial data. Conducting audits is not only a legal responsibility but also a measure of a company's financial health and reputation in the international market.
According to the regulations at Article 37 of the Independent Auditing Law 2011Auditing foreign-invested enterprises is a prerequisite for having their annual financial statements audited by independent auditing organizations. The coordination between... Decree 17/2012/ND-CP The Vietnamese Auditing Standards (VSA) have created a solid legal framework, helping to ensure transparency in foreign capital flows and profits. Let's explore these regulations in detail to ensure absolute compliance for your business.
Subjects that are required to be audited and those that are encouraged to be audited. Foreign-invested enterprises according to the latest regulations
According to current regulations, many entities are required to undergo annual independent audits to control tax and financial risks, including foreign-invested enterprises, parties to BCC contracts, credit and financial institutions, public companies, state-owned enterprises with capital exceeding 50%, and nationally important projects. In addition, the State encourages businesses, especially FDI enterprises, to conduct voluntary audits to improve governance, meet loan requirements, secure strategic partnerships, and increase transparency in business operations.

Entities subject to mandatory annual audits
In Vietnam, the identification of entities required to undergo independent audits is clearly defined to prevent tax risks and financial fraud. Auditing foreign-invested enterprises is always a top priority for inspection agencies.
Below is a detailed list of mandatory subjects under the Independent Auditing Law:
- Foreign invested enterprisesThis applies to all types of companies, from Limited Liability Companies to Joint Stock Companies, with foreign ownership.
- Parties to a Business Cooperation Contract (BCC)Especially projects with foreign involvement or large scale.

Typically, businesses opt for voluntary audits when required by banks for loan application review or when needing to provide data to strategic partners in the global supply chain. This demonstrates the professionalism of foreign-invested enterprises in auditing their business operations in Vietnam.
Legal framework governing the auditing of foreign-invested enterprises.
Auditing activities for foreign-invested enterprises are governed by several important legal documents, including the Independent Auditing Law 2011, Decree 17/2012/ND-CP, Circular 200/2014/TT-BTC, and Decree 41/2018/ND-CP. Chief accountants need to be familiar with these regulations to avoid errors and potential penalties.

Late submission may result in fines ranging from 10 to 50 million VND and negatively impact the enterprise's tax compliance.

Procedures and deadlines for submitting audit reports for foreign-invested enterprises.
Auditors of foreign-invested enterprises need to pay attention to the deadline for submitting reports to avoid being listed as late by the tax and statistics authorities. Typically, audited financial statements must be submitted within 90 days of the end of the fiscal year.
Late submission of audit reports can result in foreign-invested enterprises facing fines ranging from 10 million to 50 million VND according to Decree 41/2018/ND-CP. This not only causes financial losses but also negatively impacts the enterprise's tax compliance record.
Reasons why auditing foreign-invested enterprises should be prioritized.
Auditing foreign-invested enterprises should prioritize audits to enhance the transparency and reliability of financial reports, giving investors peace of mind for remote management and facilitating tax settlements. Audit reports are also crucial for raising capital, obtaining bank loans, or conducting M&A transactions, ensuring objective business valuation. Simultaneously, audits help businesses proactively comply with the law, control transfer pricing risks, and mitigate legal issues when tax authorities intensify their oversight.

Enhancing the transparency and reliability of data.
For foreign investors, remote operation requires an accurate financial reporting system. Independent audits provide an objective view of the financial situation of foreign-invested enterprises, giving investors peace of mind about their capital.
Audited financial statements are a crucial "passport" when auditing foreign-invested enterprises for tax settlement or dealing with customs authorities. This transparency helps shorten inspection time and minimize the risk of internal accounting errors.
Meeting the requirements for raising capital and expanding business.
When expanding their scale, foreign-invested enterprises often require financial support from banks or international credit institutions. An audit report is a mandatory document in the assessment dossier to evaluate solvency in the most transparent manner.
Furthermore, in mergers and acquisitions (M&A) transactions, the value of a foreign-invested enterprise audit will be assessed more accurately. This ensures fairness and protects the rights of all parties involved in business cooperation in Vietnam.
Comply with the law and avoid legal risks.
Vietnam is tightening its management of transfer pricing and tax evasion by foreign entities. Foreign-invested enterprises can self-assess risks related to related-party transactions and transfer pricing before being inspected by authorities.
Compliance is a solid foundation for auditing foreign-invested enterprises that want to operate long-term. Proactive auditing helps accounting departments promptly correct errors according to new tax policies, protecting businesses from complex legal risks.
Standard procedures for auditing foreign-invested enterprises.
The audit process for foreign-invested enterprises typically consists of three stages. The first stage involves system survey and planning to assess internal controls and risks. Next, auditors conduct on-site inspections, compare data, control foreign exchange transactions, and propose adjustments as needed. Finally, the audit report and management letter are issued, providing an independent opinion and recommendations to improve governance and ensure legal compliance.

System preparation and survey phase
Before beginning the audit, the auditing unit will conduct a survey of the internal control system of the foreign-invested enterprise. This step aims to assess the level of risk and develop a detailed audit plan, focusing on material items.
Accountants auditing foreign-invested enterprises need to prepare complete accounting records, original documents, and major economic contracts. Close coordination between the two parties in the initial phase will determine the progress and quality of the entire audit.
Conduct a physical inspection and verify the data.
Auditors will conduct bank balance reconciliation, inventory checks, and debt verification. For audits of foreign-invested enterprises, foreign currency transactions and exchange rate differences are always carefully controlled to ensure compliance with Vietnamese accounting standards.
During this process, adjusting entries will be proposed if there are differences between actual and book values. Auditors of foreign-invested enterprises should discuss directly with the auditor to fully understand the nature of the adjustments and learn from this experience for future accounting practices.
Issue audit reports and management letters.
The final product is an audit report with an opinion on the fairness and integrity of the financial statements. In addition, a management letter will point out weaknesses in the governance system of the audited foreign-invested enterprise and offer recommendations for improvement.
This is a valuable document for the management of foreign-invested enterprises to optimize operational processes. The insights from experienced auditing experts will help businesses improve management and prevent potential financial losses.
Common mistakes in corporate auditing foreign investment FDI
Auditing foreign-invested enterprises (FDI) often presents numerous risks due to their cross-border operations and the need to comply with multiple accounting standards simultaneously. Among these, errors in accounting for related-party transactions and confusion between IFRS and VAS are two common issues, easily leading to discrepancies in figures, difficulties in explanation, and the risk of tax assessments. Early identification of these errors helps businesses proactively improve their documentation, enhance transparency, and ensure legal compliance.
Discrepancies in accounting for related-party transactions.
Many auditors of foreign-invested enterprises face difficulties in determining the market price for transactions with the parent company. This often leads to tax assessments by the tax authorities if the audit report fails to explain the reasonableness of the incurred expenses.
The most common error is the lack of documentation proving the independence of prices. Auditors of foreign-invested enterprises need to coordinate with consulting firms to build a complete and accurate record of related-party transactions right from the start of the transaction.
Confusion between International Financial Reporting Standards (IFRS) and Vietnamese Accounting Standards (VAS)
Multinational corporations often require foreign-invested enterprises to report according to IFRS, but in Vietnam, they must comply with VAS. The differences in revenue and expense recognition between these two systems often lead to significant discrepancies in data.
The accounting team at foreign-invested enterprises must be able to seamlessly transform (mapping) financial statements. Failure to handle these discrepancies effectively will cause difficulties for the enterprise when explaining its financial situation to both the parent company and the tax authorities.
Conclude
Auditing foreign-invested enterprises in Vietnam presents both significant opportunities and stringent financial regulations. Understanding and complying with auditing requirements helps businesses avoid legal risks and gain a competitive advantage in terms of reputation. Transparent financial reporting is the foundation for the sustainable development of FDI projects in Vietnam.

Frequently Asked Questions about Business Auditing foreign investment FDI
Do newly established foreign-invested enterprises need to undergo an audit immediately?
Yes. From the very first fiscal year, foreign-invested enterprises must have their financial statements audited if they engage in business activities or capital investments. The law does not specify a minimum capital requirement for FDI businesses to be exempt from auditing.
If a business doesn't generate revenue, is an audit still necessary?
Even without revenue, if a foreign-invested enterprise incurs expenses or changes its equity capital, an audit is still mandatory. This is to determine the amount of losses carried forward to the following year and to ensure the legality of the investment capital.
How are audit fees for FDI enterprises calculated?
The fee depends on the size of the assets, revenue, and complexity of the transaction. A foreign-invested enterprise with many branches or complex foreign trade transactions will have higher audit fees than a simple representative office.
