3Frequently Asked Questions about Personal Tax Code Lookup

What should I do if I find two personal tax codes during the lookup?

This situation may occur if you have used two different ID cards/identity cards to register for tax codes. In this case, you need to terminate the later tax code for the earlier one to take effect.

Do I have a tax code if I haven’t joined the workforce yet?

Individuals who haven’t joined the workforce will have a tax code if they are dependents of their working parents or guardians who have tax codes. This is to claim a monthly deduction of VND 4.4 million for dependents. Therefore, individuals who haven’t started working yet must have a tax code, which remains valid until they join the workforce.

Do I need to change my tax code when switching from an ID card to an identity card?

No, you don’t need to change your tax code. You only need to update your information with the Tax Authority.
