I. Introduction: Why Foreign Employees MUST Obtain a Personal Tax Identification Number in Vietnam
A Personal Tax Identification Number (TIN) is a unique ID issued by the Vietnamese tax authority to manage an individual’s tax obligations.
For foreigners working in Vietnam, this number is mandatory for:
- Signing employment contracts
- Receiving income from a Vietnamese or foreign employer while working in Vietnam
- Monthly personal income tax (PIT) withholding
- Annual tax finalization
- Applying for family dependents deductions
- Claiming tax refunds
- Applying double taxation agreements (DTA) between Vietnam and other countries
Under the Law on Tax Administration 2019, any individual with taxable income in Vietnam must have a TIN.
Failure to register a TIN may result in:
- Being taxed at a flat 20% foreign non-resident rate
- Inability to finalize tax or receive refunds
- Inability to declare dependents
- Penalties under Decree 125/2020/ND-CP for non-compliance
Therefore, obtaining a TIN is not only a legal requirement but also a financial advantage for foreign professionals.

VI. Common Mistakes Foreign Workers Make When Registering a TIN (And How to Avoid Them)
1. Poor-quality passport scans
Vietnamese tax authorities often reject low-resolution scans.
Asia Legal Group solution:
We optimize scans following ICAO standards for guaranteed acceptance.
2. Incorrect date of birth or nationality entry
A very common issue.
Results:
- Duplicate TIN
- Error during tax finalization
- Inability to claim refunds
Asia Legal Group solution: Internal verification to ensure 100% accuracy before submitting to the tax authority.
3. Changing passport but failing to update information
Regulation: Must update within 10 days (Circular 105).
Failure causes:
- Incorrect residency declaration
- Inability to finalize PIT
- Loss of tax benefits under DTA
Asia Legal Group handles passport update filings on behalf of clients.
4. Missing the 10-day registration deadline after signing a contract
This is a violation under Article 33 of the Law on Tax Administration.
5. Confusing visa types with residency status
Many foreigners mistakenly assume:
- TRC = tax resident
- Visa DN = non-resident
- Visa LV1 = resident
But residency is determined by 183 days rule, not visa type.
Asia Legal Group performs OECD-standard residency assessment to minimize tax liabilities.
VII. How TIN Relates to Annual Tax Finalization for Foreigners
1. No TIN = No tax finalization
Without a TIN, foreigners:
- Are treated as non-residents
- Pay a flat 20% tax on income
- Cannot receive any refund
- Cannot register dependents
2. DTA Benefits Require a TIN
Only individuals with a TIN can:
- Avoid double taxation
- Deduct taxes paid abroad
