PIT Filing for Foreigners with Foreign-Sourced Income: A Detailed Guide

For foreigners living and working in Vietnam, complying with Personal Income Tax (PIT) regulations is crucial. The process can be particularly complex for individuals who receive their salary from a foreign country, requiring meticulous preparation.

This article uses a practical case study to clarify the necessary steps, helping you understand and fulfill your tax obligations in Vietnam correctly.

1. Case Study

Mr. John, a US citizen, moved to Vietnam in August 2025. He works remotely for a foreign organization and receives his salary in USD to his bank account in the US.

The question is: Is Mr. John required to file and pay tax in Vietnam, and what is the specific procedure?

2. A Step-by-Step Guide to Tax Filing

Under Vietnamese law, Mr. John’s tax obligations will depend on whether he is determined to be a tax resident.

Step 1: Determine Tax Residency Status

An individual is considered a tax resident in Vietnam if they:

• Reside in Vietnam for 183 days or more in a calendar year.

• Or have a permanent place of residence (a lease contract for 183 days or more).

In Mr. John’s case, although he arrived in August 2025 (less than 183 days in that calendar year), Vietnam applies a consecutive 12-month rule. If his total days of residency from August 2025 to July 2026 amount to 183 days, he will be determined to be a tax resident.

As a tax resident, Mr. John must file PIT on his worldwide income, including the salary received from abroad.

Step 2: Register for a Personal Tax Code

To file taxes, Mr. John needs to register for a personal tax code with the tax authority in his place of residence. The required documents typically include:

• Passport and visa.

• Employment contract with the foreign company.

• Housing lease contract in Vietnam.

• A prescribed registration form.

This process usually takes about 10 working days.

Step 3: Quarterly Tax Filing and Annual Tax Finalization

• Quarterly filing: Mr. John must file his taxes directly with the Vietnamese tax authorities using Form 02/KK-TNCN. The deadline is the last day of the first month of the following quarter (e.g., Q3 income must be filed by October 31st).

• Annual finalization: After the first 12 months or at the end of the calendar year, Mr. John must finalize his PIT for his entire worldwide income.

If he overpays tax and wants a refund, he will need to provide a tax payment certificate from the foreign tax authority, which must be a complex process.

3. Practical Recommendations

To ensure a smooth tax compliance process in Vietnam, consider these recommendations:

• Manage cash flow: Arrange with the foreign company to receive the full salary without any foreign tax deductions, then file and pay tax directly in Vietnam.

• Streamline procedures: Instead of going through the complex refund process for overpaid tax, individuals can opt to carry the overpaid amount forward to offset tax in future periods. This saves time and effort.

• Plan ahead: Research tax regulations as soon as you arrive in Vietnam to avoid legal risks and ensure full compliance.

If you are a foreigner facing difficulties with PIT filing and finalization, seeking professional assistance is essential. A reputable tax advisory firm can help you understand the regulations, optimize your tax obligations, and ensure all procedures are carried out correctly, giving you complete peace of mind.
