Import and export businesses often face a mismatch between customs clearance and invoice issuance. This guidance document resolves a long-standing legal bottleneck.
Through these directives, the tax authorities clearly define the boundary between VAT obligations and revenue accounting. This provides a solid legal basis for independent audits and tax settlements.

Furthermore, the document protects the rights of businesses against disputes regarding the timing of deductible expenses when determining corporate income tax. Businesses can easily provide logical explanations to tax inspectors during tax settlement periods.
Which entities are directly affected by Official Letter 7533/TNI-QLDN2?
The scope of this guideline is not limited to Tay Ninh province but also serves as a reference for the entire Vietnamese business community. Accurately identifying the affected groups helps all parties proactively implement the guidelines.
- The first group consists of businesses operating in the export and processing of goods for export. These entities often engage in complex foreign exchange transactions and transport goods through multiple customs checkpoints.
- The second group includes organizations and individuals providing services with advance payment transactions or receiving deposits from customers. Managing the timing of invoicing in this case is very prone to errors.
- The third group consists of accounting personnel, internal auditors, and tax agents. These are the people directly responsible for operating the documentation system and declaring financial obligations to the State.
How to determine the timing and exchange rate for issuing VAT invoices for exported goods according to Official Letter 7533/TNI-QLDN2?
Incorrectly determining the timing of export invoice issuance is one of the most common errors leading to administrative fines for invoice violations. The guidance in the official document clarifies the maximum time frame and rules for determining exchange rates for export activities. Businesses engaged in exporting goods (including processed goods for export) must strictly adhere to principles regarding the timing and exchange rates of transactions.
Time of invoicing for export goods
According to Clause 1, Article 9 of Decree 254/2026/ND-CP, the time of issuing a sales invoice for goods in general is the time of transferring ownership or the right to use the goods to the buyer, regardless of whether payment has been received or not. However, for goods exports (including processing for export), the time of issuing the electronic commercial invoice, electronic VAT invoice, or electronic sales invoice is determined by the seller, but no later than the next working day from the date the goods are cleared through customs as stipulated by customs law. In cases where businesses use internal warehouse release and transportation slips to transport goods to ports or customs clearance locations, the management and documentation must comply with the regulations specified in point c, clause 3, Article 6 of Decree 254/2026/ND-CP.
Exchange rate when issuing VAT invoices in foreign currency.
When issuing VAT invoices for exported goods denominated in foreign currency, businesses must clearly state the exchange rate to Vietnamese Dong (VND). Based on the guidance in point c, clause 8 of the Appendix issued with Decree 254/2026/ND-CP, the exchange rate recorded on the invoice is determined specifically according to the regulations on the actual transaction exchange rate or the accounting exchange rate at the time the transaction occurs. Accountants need to be mindful of recording the correct exchange rate of the commercial bank where the business has its transaction account at the time of invoice creation to avoid discrepancies in cash flow.
Accounting and recording of export revenue
To accurately record expenses and prepare financial statements, the company must consistently apply the principles set forth in Circular 99/2025/TT-BTC. The company determines its tax obligations based on the actual circumstances and makes declarations on the VAT tax return and the corporate income tax final settlement return in accordance with the law. Exchange rate differences between the time of customs clearance, the time of invoicing, and the time of actual collection of foreign currency must be accurately reflected in the financial operating revenue or financial expense account for the period.
What are the regulations regarding the timing of issuing service invoices when payment is collected in advance?
Many businesses often confuse advance payments for services with deposits, leading to delays in invoicing and subsequent tax audits by the tax authorities. (Clause 2, Article 9) Decree 254/2026/ND-CP These legal boundaries have been clearly defined.
For service provision activities (including providing services to foreign organizations and individuals), the general principle is that the time of invoice issuance is the time when the service is completed, regardless of whether payment has been received or not.
If the service provider collects payment before or during the provision of services, the time of invoice issuance is the time of payment.
The only exception: In cases where a deposit is collected in accordance with the Civil Code to guarantee the performance of a service contract, an invoice does not need to be issued at the time the deposit is received.
In cases of multiple deliveries or handover of individual items or service stages, an invoice must be issued for each delivery or handover, specifying the quantity and value of goods or services delivered, in accordance with Clause 3, Article 9 of Decree 254/2026/ND-CP.
Experts at MAN emphasize that the nature of the contract and payment receipts will determine whether the amount is an "advance payment" or a "deposit." If the contract states it's a deposit but it's essentially a prepayment according to the progress schedule, the tax authorities have grounds to consider it a delay in issuing the invoice.
Legal responsibilities of buyers of goods and services when using invoices.
Not only is the seller responsible for the legality of the invoice, but the buyer also bears strict legal obligations when including the invoice in the accounting of deductible expenses and input VAT deductions.
According to Clause 3, Article 18 of Decree 254/2026/ND-CP, buyers of goods and services have two core responsibilities:
- Use invoices for their intended purpose: Purchase invoices must directly serve the legitimate production and business activities of the enterprise. The buying, selling, and use of fictitious or illegal invoices to legitimize expenses is strictly prohibited.
- Provide invoice information: It is the responsibility to proactively and promptly provide the information recorded on invoices to competent state agencies when requested for inspection or audit.
When the buyer fails to fulfill this responsibility, all related costs may be disallowed as deductible expenses for corporate income tax purposes, and they may also be subject to retroactive collection of VAT and late payment penalties.

Practical Case Study: Managing Exchange Rate Risk and Invoice Timing in Export Businesses
Below is a real-life case study that tax consultants at MAN directly assisted in resolving for a client in the agricultural processing and export sector in Tay Ninh in Q3/2026.
Situational context
Moc Xanh Joint Stock Company is exporting cassava starch to the European market.
- September 10, 2026: Goods completed customs clearance procedures (Green channel declaration). Shipment value: USD 100,000. Exchange rate on the customs declaration: VND 25,400/USD.
- September 12, 2026 (Sunday): Weekend holiday.
- September 15, 2026: The new accountant will issue the electronic VAT export invoice. Bank exchange rate on September 15, 2026: 25,500 VND/USD.
Legal risks and expert analysis
Upon reviewing the records, MAN's tax risk management department identified two serious violations:
- Regarding the timing of invoice issuance: The customs clearance date is Friday (September 10, 2026). According to Clause 1, Article 9 of Decree 254/2026/ND-CP, the next working day should be Monday (September 13, 2026). The business issuing the invoice on September 15, 2026, is two working days late. This action violates the regulations regarding the timing of invoice issuance.
- Regarding accounting exchange rate differences: The accountant used the exchange rate of September 15, 2026 (25,500 VND/USD) to record revenue on the invoice instead of the accurate exchange rate on the date of the legally issued invoice (September 13, 2026, which is 25,420 VND/USD), causing discrepancies in revenue for VAT and corporate income tax purposes.
The solution from MAN
To correct errors and minimize penalties, the solution from MAN – Master Accountant Network is implemented as follows:
- Proactively prepare a record to correct erroneous electronic invoices, adjusting the issuance date and exchange rate to the correct date of September 13, 2026.
- Submit supplementary VAT tax returns and adjust accounting records in accordance with Circular 99/2025/TT-BTC before the tax authority issues an inspection decision.
- Providing detailed written explanations of objective reasons helps businesses minimize administrative penalties to the minimum level stipulated by tax regulations.
MAN experts' assessment of tax risks and practical audit experience.
From MAN's perspective, the new regulations in Official Letter 7533/TNI-QLDN2 and Decree 254/2026/ND-CP have tightened data connectivity between Customs and Tax authorities. Any discrepancies in time and value are automatically alerted by the tax sector's risk management system.
In practice, auditing and tax settlement for hundreds of FDI enterprises and large import-export businesses in Vietnam have revealed the following common errors:
- Not closely monitoring the customs clearance date: Accountants often wait for original documents or notifications from the logistics service provider before issuing invoices, resulting in invoices exceeding the "next business day after customs clearance".
- Confusion between customs exchange rates and invoice exchange rates: The exchange rate on the customs declaration is used to calculate import and export taxes. The exchange rate on the electronic invoice is used to account for sales revenue. Using the wrong exchange rate will lead to discrepancies in corporate income tax obligations.
- Deliberately recording advance payments as deposits: The purpose was to postpone the issuance of the VAT invoice. When the tax authorities inspected the economic contract and cash flow, the entire amount of output VAT was collected retrospectively, along with a late payment penalty of 0.031 TP3T/day.
With over 30 years of experience, MAN's team of experts advises businesses to immediately establish an automated coordination process between the Import/Export and Accounting departments. Simultaneously, businesses should conduct periodic tax health checks to detect and address invoice discrepancies promptly before the tax settlement period.
