Digital tax system Vietnam compliance 2026
In line with the Government’s directive to accelerate digital transformation, the Tax Department is implementing a series of solutions applying AI, big data, and biometrics to tax management. This trend not only helps increase transparency and combat fraud but also facilitates citizens and businesses in fulfilling their digital tax system Vietnam compliance.
1. Building a data- and AI-based tax management system
Identifying digital transformation as a central and continuous task, the Tax Department is gradually shifting from a traditional management model to smart governance based on data and digital technology. According to the Technology, Digital Transformation and Automation Department of the Tax Department, the implementation of the Tax System Reform Strategy to 2030 and Resolution 57-NQ/TW on national digital transformation has created a foundation for the Tax Department to form a centralized data ecosystem, interconnected with ministries, sectors, and localities.
To realize this goal, the tax sector is focusing on three major pillars: building a centralized big data system; connecting and sharing inter-sectoral data through open APIs; and implementing a Compliance Relationship Management (CRM) system, shifting strongly from a “management” mindset to one of “partnering with and serving” taxpayers.
According to Deputy Director of the Tax Department Dang Ngoc Minh, digital transformation is a long journey but offers great opportunities to comprehensively change the method of electronic invoicing changes Vietnam law. The application of technology not only helps improve the efficiency of state management but also facilitates citizens and businesses, reduces compliance costs, and increases the transparency of the business environment.
2. AI supports tax filing, biometrics prevent fraud
One of the highlights in the digital transformation roadmap of the Tax sector is the application of AI to support tax filing using natural language on the e invoice system upgrade Vietnam 2026 platform.
Accordingly, taxpayers, especially business households, only need to answer simple questions from the virtual assistant instead of having to fill out complex forms themselves. The AI system will automatically identify the business location, calculate tax obligations, and create a complete electronic tax return.

The entire filing process only takes about 1-2 minutes. In the future, when electronic invoice data is synchronized, many data entry steps will continue to be automated, moving towards a “nearly contactless tax filing” model.
From October 2025, the eTax Mobile application will also include an AI chatbot to assist in looking up information about income, dependents, real time tax reporting Vietnam requirements, or temporary travel bans due to tax obligations.
In parallel with facilitating taxpayers, the Tax Department is also strengthening security solutions to prevent fraudulent business activities and illegal invoice trading.
According to Pham Quang Toan, Head of the Technology, Digital Transformation and Automation Department, the tax authorities will implement biometric authentication when registering to use electronic invoices on eTax Mobile.
When businesses register for a new service or change the information of their legal representative, the system will require facial authentication and compare it with the National Population Database. If the data does not match, the application will be rejected.
This solution is expected to curb the use of forged documents to establish “phantom” businesses, buy and sell invoices, or exploit leaked personal information to commit illegal acts.
According to the plan for 2030, the tax sector will continue to build a Big Data Center, applying AI and Machine Learning in transaction analysis, fraud detection, risk scoring, and management decision support.
The combination of big data, AI, and biometrics is expected to create a foundation for a modern, transparent digital tax ecosystem, contributing to a healthy business environment and sustainable digital economic development.

3. Assessing the Role of Accounting and Auditing in Tax Compliance Risk Management
In invoice data integration tax authority Vietnammanagement, accounting and auditing hold a central position because these two fields directly create, verify, and confirm the reliability of financial information, which forms the basis for determining the tax obligations of taxpayers.
Practice in Vietnam shows that most tax compliance risks discovered through inspections and audits stem from discrepancies in accounting recording, expense classification, determination of taxable revenue, and handling of complex transactions. This reflects the close relationship between the quality of accounting work and the level of tax compliance of businesses.
Overall, S4B Vietnam perspective suggest that managing tax compliance risk is not solely a matter for the tax authorities, but should be approached as an integral part of the quality of accounting, auditing, and financial transparency of businesses.
