Post-establishment procedures for a construction company in Vietnam
Applying for a sub-license is one of the important procedures after establishing a construction company. If the construction company registers for a group of common civil and industrial sectors, without specific requirements on capital, qualifications or experience, it does not need to apply for a sub-license. However, for some specialized industries, after establishing a construction company, it is necessary to apply for a sub-license from the competent authority. Specifically, these industries include:
According to Clause 4, Article 37 of the Law on Enterprise 2020, the company name must be attached to the company’s headquarters, branches, representative offices, and business locations. This is a mandatory regulation, one of the ways to prove the legal existence of a construction company. If not complied with, the company will be subject to administrative sanctions.

Required information for a company nameplate
According to Article 34 of the Advertising Law 2012, company nameplates must have the following information:
After establishing the company, the company owner needs to go to the bank and open a company account. After having an account, the company needs to draft an official letter and send it directly to the Tax Authority in charge so that this authority can confirm that the account number exists and is the bank account of the construction company.
Note: Personal bank accounts cannot be used for newly established companies. Therefore, the company owner must open a separate account for the company and cannot use their own personal account.
