Disclosure is usually performed automatically by the Business Registration Office if you choose the public service when submitting the application.
If submitting directly or via post, it is recommended to check the disclosure status at dangkykinhdoanh.gov.vn.
2. Display the Company Name Board
Regulation:
According to Article 37 of the 2020 Enterprise Law, the company’s office must have a signboard clearly displaying:

7. Choose the Method for Calculating Value-Added Tax (VAT)
Two methods for calculating VAT:
-
Deduction method – applied to enterprises with revenue over VND 1 billion or voluntarily registered.
-
Direct method on revenue – for small enterprises and household businesses.
Tasks to perform:
-
Submit the VAT calculation method registration form to the tax authorities.
-
Prepare initial tax declaration documents:
-
Register the accounting method
-
Decision appointing chief accountant or hiring accounting services

8. Set Up the Accounting System
-
Legal basis: According to the 2015 Accounting Law, when an enterprise is established, it must set up an accounting system, record economic transactions, maintain books and documents, and prepare tax reports.
-
Two forms of accounting organization:
-
Internal accounting department: The enterprise builds its own accounting team (usually applied to medium and large enterprises with many financial transactions).
-
Outsourced accounting service: For small, newly established enterprises that want to save costs and use professional services.
-
Steps to implement:
- Appoint or contract a chief accountant or accounting service provider.
- Develop internal finance and accounting regulations: rules for income and expenditure, payments, and document management.
- Set up accounting books, determine the appropriate accounting method, and prepare internal decision templates.
- Store documents and reports in compliance with accounting and tax regulations (e.g., retain electronic invoices for at least 10 years).
Additional note: Many newly established enterprises skip this step or do it formally → leading to risks during inspections and administrative fines if audited by the tax authorities.
