2. Are dependents eligible for a Tax Identification Number (TIN)?

According to Clause 3, Article 30 of the 2019 Law on Tax Administration, an individual’s dependents are issued a tax code. This tax code is used for the purpose of personal relief when calculating personal income tax. It is noteworthy that the tax code issued to the dependent will also become their personal tax code when the dependent incurs tax obligations to the state budget in the future.

3. Regulations on issuance of tax identification numbers:

a) Enterprises, economic organizations, and other entities are issued a single TIN to be used throughout their entire operation, from tax registration until deactivation. Taxpayers with branches, representative offices, or dependent units that directly fulfill tax obligations are issued dependent TINs. If registration is conducted through a one-stop mechanism along with business registration, the business registration number also serves as the tax code.

b) Each individual is issued one unique TIN to be used throughout their lifetime. Dependents of taxpayers are also issued TINs for the purpose of family circumstance-based deductions for PIT. The TIN assigned to a dependent will later serve as that individual’s TIN when they become liable for tax obligations to the state budget.

c) Enterprises, organizations, and individuals responsible for withholding or paying taxes on behalf of others are issued a substitute TIN to declare and remit taxes on behalf of the taxpayer.

d) A TIN once issued shall not be reassigned to another taxpayer.

đ) The TIN of an enterprise, economic organization, or other entity remains unchanged in cases of conversion, transfer, inheritance, or restructuring.

e) The TIN issued to a household, household business, or individual business is the same as the TIN of the household representative or the individual conducting the business.
