What are the 5 issues regarding the use of personal identification numbers in place of personal identification numbers by 2025 in Vietnam?
Below is a comprehensive summary of the five issues regarding the use of personal identification numbers in place of personal identification numbers according to Circular 86/2024/TT-BTC:
(1) Deadline for Mandatory Use of personal identification numbers in Place of personal identification numbers:
Based on Clause 2, Article 38 of Circular 86/2024/TT-BTC, the personal identification numbers issued by the tax authorities to individuals, households, and businesses will be implemented until June 30, 2025. Starting from July 1, 2025, taxpayers, tax authorities, organizations, and individuals involved in using personal identification numbers as per Article 35 of the Law on Tax Management 2019 will use personal identification numbers instead of personal identification numbers.
Thus, the mandatory period to use personal identification numbers in place of personal identification numbers begins on July 1, 2025.
(2) Use of personal identification numbers When Individual tax registration Information Matches National Database on Civil Information:
Per Clause 2, Article 39 of Circular 86/2024/TT-BTC, the use of personal identification numbers in this case is stipulated as follows:
If businesses, households, or individuals fitting the criteria for using personal identification numbers instead of personal identification numbers—as stated in Clause 5, Article 5 of Circular 86/2024/TT-BTC—have been issued personal identification numbers before July 1, 2025, and their tax registration information matches the individual information stored in the National Database, they will use their personal identification numbers starting from July 1, 2025, including adjusting tax obligations previously assigned by the previous tax number. Tax authorities will also manage the entire data of these entities using the personal identification numbers.
(3) Use of personal identification numbers When Individual tax registration Information Does Not Match the National Database:
According to Clause 3, Article 39 of Circular 86/2024/TT-BTC, if businesses, households, or individuals issued a tax number before July 1, 2025, have mismatched registration information, the tax authorities will assign the tax number to the "Tax Number Awaiting Personal Identification Number Update" status. Taxpayers must update their registration information per Clause 1, Clause 4, Article 25 of Circular 86/2024/TT-BTC before using personal identification numbers as stated in Clause 2, Article 38 of Circular 86/2024/TT-BTC.
(4) Use of personal identification numbers When an Individual Has More Than One Tax Identification Number:
As per Clause 4, Article 39 of Circular 86/2024/TT-BTC, if individuals possess more than one tax identification number, they must update their personal identification details accordingly to integrate their tax data under a single personal identification number.
Legal instruments involving the use of the previous tax number will remain valid for tax administration purposes, even after integration.
(5) If the Individual Has Not Been Issued a Personal Identification Number:
Clause 4, Article 40 of Circular 86/2024/TT-BTC stipulates that Vietnamese citizens not yet issued a personal identification number must contact the local police authority for information collection into the National Database for Civil Information, to receive a personal identification number before undertaking tax registration procedures as per Circular 86/2024/TT-BTC.
