In 2025, PIT finalization for expatriates demands absolute precision in determining residency status and declaring global income. To ensure legal compliance and avoid administrative penalties, businesses must master the deadlines, dependent documentation requirements, and the latest regulations on electronic transactions.
1. Expatriates Subject to PIT Finalization
Correctly identifying the subject is the prerequisite step to applying the appropriate tax rate. Under current regulations, foreigners working in Vietnam are divided into two main groups based on their duration of stay and residence.
Resident Individuals
An individual is identified as a resident of Vietnam if they satisfy one of the following conditions:
-
Being present in Vietnam for 183 days or more within a calendar year or within 12 consecutive months from the first day of arrival in Vietnam.
-
Having a regular residence in Vietnam according to the law on residence or having a leased house for stay in Vietnam with lease contracts of 183 days or more within the tax year.
For resident individuals, taxable income is income arising within and outside the territory of Vietnam, regardless of where the income is paid.
Non-resident Individuals
Individuals who do not meet the above conditions are considered non-residents. This group is only liable for PIT on the portion of income arising in Vietnam at a flat tax rate of 20%, with no family relief deductions allowed.
Authorized Finalization Cases
A business may perform the finalization on behalf of an employee if that individual only has income from wages or salaries, has signed a labor contract of 3 months or more with the business, and is actually working there at the time of finalization.
2. Standard PIT Finalization Process for Foreign Experts
To ensure accuracy and optimize time, businesses should apply a streamlined yet comprehensive control process as follows:
-
Review and Collect Documents: Gather all tax withholding certificates, Letters of Confirmation for income paid abroad, and invoices/documents related to insurance or charities.
-
Determine Deductions: Check family relief records for the individual and their dependents. Note that dependent documents from abroad must be consularly legalized in accordance with regulations.
-
Prepare and Submit Declarations: Use the latest HTKK software or declare online via the General Department of Taxation’s e-portal. Ensure that taxable income and withheld tax figures match the accounting books.
-
Tax Payment or Refund: After submission, the business or individual pays any additional tax (if underpaid) or proceeds with tax refund/offset procedures for the next period (if overpaid).
3. Updates on the Latest 2025 Legal Regulations and Decrees
The year 2025 marks a turning point in the digitalization of tax management. Decree 126/2020/NĐ-CP and Law on Tax Administration No. 38 remain the primary legal frameworks, but new guiding circulars have emphasized the following:
-
Personal Digital Signatures: Individuals performing self-finalization are encouraged and gradually required to have a digital signature or register an e-tax transaction account to approve documents online.
-
Submission Deadlines: For individuals performing self-finalization, the deadline is the last day of the 4th month from the end of the calendar year. For businesses finalizing on behalf of employees, the deadline is the last day of the 3rd month.
-
Global Income Processing: Tax authorities are increasing the review of international tax information exchange data to monitor income earned outside of Vietnam by foreign experts.
4. Calculating PIT for Expatriates with Global Income
This is the most complex aspect of tax finalization. For resident individuals, income from all sources worldwide must be converted into Vietnam Dong (VND) using the average interbank foreign exchange market rate at the time the income arises.
Applying Double Taxation Agreements (DTA)
Vietnam has signed DTAs with over 80 countries and territories. If a foreigner has paid income tax in their home country (e.g., Japan), they may deduct the tax paid abroad from the tax payable in Vietnam, provided it does not exceed the tax payable calculated under Vietnam’s tax tariff.
Utilizing DTAs effectively not only ensures compliance with international law but also helps businesses significantly optimize senior personnel costs.
| Monthly Taxable Income (Million VND) | Tax Rate |
| Up to 5 | 5% |
| Above 5 to 10 | 10% |
| Above 10 to 18 | 15% |
| Above 18 to 32 | 20% |
| Above 32 to 52 | 25% |
| Above 52 to 80 | 30% |
| Above 80 | 35% |
5. Required Documents for Expatriate PIT Finalization
A well-prepared dossier will help businesses shorten the processing time with tax authorities. Essential documents include:
-
Tax finalization return Form No. 02/QTT-TNCN (for individuals) or 05/QTT-TNCN (for organizations).
-
Appendix listing details of dependents for family relief.
-
Certified copy of passport to verify the number of days stayed in Vietnam.
-
Tax withholding certificates and global income confirmation from the parent company or paying entity abroad.
-
Dependent supporting documents (if any): Birth certificates, marriage certificates—consularly legalized and notarized with translation.
6. PIT Refund for Foreigners upon Completion of Assignment in Vietnam
When foreign experts finish their term and leave Vietnam, they must perform tax finalization up to the date of departure. This is a crucial step to close the tax identification number (TIN) and complete obligations to the Vietnamese state.
In many cases, the monthly withheld tax is higher than the actual tax payable based on the actual working time. In such instances, the individual is entitled to a tax refund. Vina Boueki recommends that businesses support experts in completing this procedure before they leave the territory to ensure their rights and avoid future legal complications should they wish to return to work.
7. Common Mistakes and Legal Risks for Businesses
Below are the errors Vina Boueki frequently records during consulting:
-
Incorrect Determination of Residency Status: Calculating a flat 20% tax for the entire year when the individual was actually in Vietnam for over 183 days.
-
Omission of Income: Failing to declare cash allowances or non-monetary benefits (such as tuition for children or home leave airfare) which are taxable.
-
Invalid Deduction Documents: Using overseas documents without the mandatory consular legalization stamp from the Vietnamese consulate.
-
Late Submission: Leading to high administrative tax penalties as stipulated in Decree 125/2020/NĐ-CP.
