Official Letter No. 1902/CT-CDS: A Wake-Up Call for Vietnamese Businesses Operating “Dual Accounting Systems”

On 31 March 2026, the General Department of Taxation of Vietnam issued Official Letter No. 1902/CT-CDS, calling for coordinated action to prevent tax fraud through the use of multiple financial accounting systems.

Although the Official Letter is formally addressed to providers of e-invoicing solutions, accounting software, point-of-sale (POS) systems, and electronic tax service platforms, its message extends far beyond the technology sector. It delivers a clear signal to Vietnam’s business community: the era of managing businesses with two sets of financial records is coming to an end.

According to the tax authority, some businesses continue to operate two or more financial accounting systems within the same accounting period. One system is used for statutory reporting to tax authorities, while another records the company’s actual revenues and business activities for internal purposes. Such practices are often intended to understate taxable income and reduce tax liabilities.

This is not merely poor governance—it constitutes a serious violation of Vietnam’s accounting and tax legislation and, in certain circumstances, may expose businesses to criminal liability.

A Robust Legal Framework

Official Letter No. 1902/CT-CDS explicitly refers to several key legal provisions:

• Clause 10, Article 13 of the 2015 Law on Accounting, which prohibits maintaining two or more financial accounting systems or issuing inconsistent financial statements for the same accounting period.
• Article 17 of the 2019 Law on Tax Administration, requiring taxpayers to submit tax declarations that are accurate, truthful, complete, and legally accountable.
• Article 143 of the 2019 Law on Tax Administration, which classifies the omission of taxable revenues from accounting records as an act of tax evasion.
• Article 221 of the 2015 Penal Code, establishing criminal liability for serious violations of accounting regulations, including maintaining multiple accounting systems to conceal assets, liabilities, revenues, or financial resources.

The Tax Authority Is Also Targeting Technology Providers

One of the most significant aspects of the Official Letter is that the General Department of Taxation is not focusing solely on businesses.

Software developers and technology providers are requested not to design, integrate, market, or support accounting solutions capable of operating multiple accounting systems.

Furthermore, software providers are encouraged to incorporate:

• automated audit trails;
• data change history;
• anomaly detection mechanisms; and
• seamless integration between sales systems, accounting software, and electronic invoicing platforms to ensure that transaction data is transmitted completely and automatically to the tax authority.

This represents a major step toward building a fully digital, transparent tax administration ecosystem.

A Fundamental Shift in Corporate Governance

For many Vietnamese SMEs, maintaining separate “internal books” and “tax books” was once regarded as a practical management approach.

However, in today’s environment—where electronic invoices, digital banking, POS systems, accounting software, and tax databases are increasingly interconnected—this practice has evolved into a significant legal and financial risk.

Data inconsistencies can now be detected far more easily through automated cross-checking between multiple digital systems.

The cost of maintaining dual accounting records is becoming exponentially higher than any perceived short-term tax benefit.

One Accounting System: A Financial Passport to Global Capital

From the perspective of sustainable business development, maintaining one transparent accounting system is no longer simply about complying with tax regulations.

It has become a prerequisite for accessing international sources of finance—particularly green finance, impact investment, and ESG-linked capital.

International investors, development finance institutions, and impact funds do not evaluate businesses solely on innovative products or compelling social impact stories.

They assess businesses through measurable evidence:

• genuine revenue;
• genuine cash flow;
• genuine costs;
• genuine profitability; and
• genuine governance capability.

For this reason, a single transparent accounting system has become a financial passport enabling Vietnamese enterprises to access international capital markets—where trust is built not through promises, but through verifiable data, reliable reporting, and governance systems capable of independent validation.

More Than an Anti-Fraud Measure

Official Letter No. 1902/CT-CDS should therefore be viewed as more than an anti-tax-fraud initiative.

It reflects the Vietnamese Government’s commitment to a new governance standard:

Every economic and financial transaction must be recorded accurately, completely, promptly, and consistently within one unified financial accounting system.

Three Immediate Priorities for Businesses

Businesses should promptly:

• review all accounting, sales management, inventory management, and electronic invoicing software currently in use;
• reconcile revenue, invoices, banking transactions, receivables, inventory records, and accounting data; and
• eliminate any operating model that creates or supports multiple sets of financial records.

Transparency Is No Longer Optional

In the era of digital taxation, transparency is no longer simply an ethical principle.

It has become a fundamental requirement for business survival.

Transparency determines a company’s ability to:

• comply with tax regulations;
• obtain bank financing;
• attract investment;
• improve enterprise valuation;
• participate in global supply chains; and
• achieve sustainable long-term growth.

From the perspective of EDUBELIFE and BIZMAP, businesses that establish transparent accounting systems today are not merely reducing legal risks—they are building the institutional trust required to compete in the global economy.
