• Accurate information about the full name and date of birth of the dependent

Common errors when registering for dependent deduction via VNeID

During the process of adding dependents on VNeID 2026, users may encounter some technical problems. Here are quick solutions for common cases:

Information does not match the national database

• Cause: The demographic data (full name, date of birth, address) of the dependent on the tax system or old documents is inconsistent with the data on the National Population Database.
• Solution: You need to bring the citizen identification card or birth certificate of the dependent to the Commune/Ward Police where you permanently reside to request checking, updating, and correcting the identification information accurately.

Dependent has already been registered by someone else

Example: The husband has registered the deduction for the child; when the wife continues to register for that same child, the system will report an error.

• According to the provisions of Clause 3, Article 10 of the Personal Income Tax Law 2025, the principle of calculating family circumstance deductions is: “Each dependent is only calculated for deduction once for one taxpayer”.
• The family needs to agree for only one person to register. If you want to change the direct deductor (e.g., switch from father to mother), the current registrant must complete the procedure to reduce the dependent before the other person proceeds with the new registration.

System reports “Request is being processed” for too long

Due to the number of users registering dependents on VNeID at the same time, local overload may occur. You should check the “Request history” section again after 24h – 48h.

If there are still no results after 7 working days, you can contact the VNeID support switchboard or the one-stop department of the managing Tax Department to request support in checking the data flow.

Do I need to notify Human Resources (HR) after registering for dependent deduction via VNEID?

Even though you have successfully registered the dependent on VNeID, this only resolves the “data” part between the taxpayer and the Tax authority. To ensure the monthly PIT amount is directly deducted on your payroll, notifying the company’s HR is necessary to:

• Update the payroll software: HR cannot automatically access your personal VNeID account to know who you have added. They need the information to enter into the company’s payroll system.
• Year-end tax finalization: The company is the entity that pays income and performs tax finalization on your behalf. If HR does not have dependent information, they cannot apply the deduction during finalization.
