Understanding Tax Audits for Representative Offices in Vietnam
The purpose of tax audits for representative offices in Vietnam is to establish their payable tax by meticulously examining all expenses during the tax term for tax declaration and payment. Over recent years, the frequency of these audits has increased significantly, particularly when a representative office closes its tax code. This uptick in audits underscores the need for constant preparedness and compliance.
Representative offices in Vietnam must submit activity reports for the previous year to the Department of Industry and Trade by January 30 each year. This annual report submission is a critical component of the audit process, and timely and accurate report submission can prevent unnecessary complications and delays during audits.
One of the common challenges faced during tax audits is the frequent data requests and inquiries made by tax authorities. These can be overwhelming and time-consuming if not handled efficiently. A robust system for maintaining and retrieving records can significantly ease the audit process, making all necessary documentation readily available.

Key Points of Tax Audits for Representative Offices
Tax audits for representative offices in Vietnam predominantly focus on verifying expenses rather than revenue, as these offices do not independently generate income. This unique aspect means that the audit process revolves around scrutinizing the financial transactions and expenses recorded by the office. Therefore, maintaining detailed and accurate records of all expenses is crucial.
Although representative offices are not mandated to maintain detailed accounting records, it is highly advisable to keep comprehensive expense reports and supporting documents to facilitate audits. Proper documentation can prevent the disallowance of input VAT credits and deductions for corporate income tax, which could otherwise result in additional liabilities. All expenses should be well-documented and justified to ensure audit readiness.
Tax audits are typically initiated upon the closure of a representative office’s tax code. This requires thorough documentation and reporting of all relevant expenses. Organizing annual reports and adhering to submission deadlines helps avoid unnecessary complications during a tax audit. A proactive approach to maintaining compliance and readiness can make the audit process smoother and more efficient.
Personal Income Tax (PIT) Filing and Payment
A representative office must declare its Personal Income Tax (PIT) returns during its operation. This is a necessary obligation for compliance. The deadline for filing and payment of monthly PIT returns is the 20th day of the subsequent month. Timely submission of these returns is crucial to avoid complications with local tax authorities. Documenting all payments properly ensures compliance with tax regulations in Vietnam.
For domestic transactions, contracts and purchase orders are particularly important, especially for higher-value expenses. For international payments, maintaining customs documents, commercial invoices, and import tax payment receipts is mandatory. These documents serve as proof of the legitimacy of transactions and are critical during tax audits, which is why it is essential to discuss the key points.
Acceptable payment documentation includes bank transfer vouchers or cash payment receipts, depending on the transaction amount. Accounting vouchers, which often require signatures from accountants and company heads, validate financial entries and ensure that all transactions are accounted for correctly. Meticulous record-keeping and adherence to sufficient supporting documents facilitate smooth PIT filing and payment processes.

Avoiding Common Pitfalls in Tax Compliance
One common misconception among representative offices is that they do not need to maintain accounting records. This belief can lead to significant issues during tax audits. Vietnamese tax authorities are intensifying their focus on areas like personal income tax, which affects both representative offices and their employees. Not maintaining proper documentation for expenses can complicate matters during tax inspections and lead to penalties.
Insufficient documentation during tax audits can result in the disallowance of input VAT credits and deductions for corporate income tax, leading to additional liabilities. The penalties for tax non-compliance in Vietnam can vary widely, from minor administrative fines to significant tax penalties that may exceed the additional tax owed. Awareness of potential consequences and maintaining thorough records are crucial.
The statute of limitations for tax penalties in Vietnam is five years, but in cases of tax evasion, authorities can pursue unpaid taxes indefinitely. Decree 125/2020 establishes various penalties for tax and invoicing violations, effective December 5, 2020. Adhering to these regulations is critical to avoid legal issues and severe penalties.

Preparing Comprehensive Expense Reports
A comprehensive expense report helps avoid challenges from tax authorities during audits. Suggested documents to include in these reports are VAT invoices, financial policies, approved expense reports, and copies of bank payments. Representative offices should ensure that all expenses are well-documented and justified to facilitate smooth audits.
Having a structured planning process helps ensure that all documentation required for audits is accurately retained and easily accessible. Utilizing digital tools for accounting and invoicing can streamline the documentation process, making audits more efficient. These tools can help organize and store records systematically, reducing the risk of missing or incomplete documentation during audits.
A proactive approach to documentation and reporting can significantly ease the audit process. Accurate records and necessary documentation help representative offices navigate tax audits more effectively.
Consequences of Non-Compliance
Representative offices often face challenges if they neglect to register their employees for social insurance and other mandatory contributions. Failing to comply with these obligations can lead to significant administrative challenges and complications during audits including:
- Administrative penalties of 20% or from 1 to 3 times the evaded PIT liabilities for tax fraud or evasion
- Late payment interest on overdue PIT at a rate of 0.03% per day
Additionally, representative offices must submit an annual activity report to the Department of Industry and Trade by January 30, which is an integral part of the audit process.

Role of Parent Company in Supporting RO Compliance
The parent company plays a crucial role in ensuring that its representative offices comply with local tax regulations. By providing necessary resources, guidelines, and support for preparing comprehensive tax documentation, the foreign company can help the representative office navigate the complexities of tax compliance.
Representative offices need to register for a tax identification number with the tax authority as part of their compliance with Personal Income Tax (PIT) obligations. Regular communication and updates from the parent company help ensure that the representative office is aware of any changes in tax legislation or compliance requirements.
Parent companies can also assist by providing training and support to key staff members, ensuring that they are well-prepared to handle tax audits and compliance requirements.
