Vietnam PIT Finalization: 2026 Filing Guide for Foreign Employees
Foreign employees working in Vietnam may need to complete annual personal income tax finalization even when their employer has withheld tax from monthly salary payments.
Vietnam PIT finalization is the process of reconciling an individual’s total taxable employment income, permitted deductions, tax already withheld and final tax liability for the relevant tax year. The process determines whether the employee must pay additional tax, is entitled to a refund or has fully satisfied the tax obligation.
The procedure can become more complicated when an employee receives income from multiple companies, is paid partly from overseas, changes employers, claims foreign tax credits or leaves Vietnam before the end of the year.
This guide explains who must complete PIT finalization in Vietnam, when an employee can authorize an employer to file, which documents are required and what foreign employees should do before leaving the country.
Key Takeaways
Annual PIT finalization generally applies to Vietnamese tax residents earning salary or employment income.
Eligible employees may authorize their employer to complete PIT finalization on their behalf.
Employees with multiple material income sources, overseas income or special deductions may need to file directly.
For the 2026 tax year, an income-paying organization generally files by the last day of the third month following year-end.
A resident individual filing directly generally files by the last day of the fourth month following the calendar year.
A resident foreign employee ending employment in Vietnam must finalize PIT before departure or authorize another organization or individual to complete the procedure.
The 2026 PIT calculation uses the new family deductions and five-bracket progressive tax table applicable to resident employment income.
The forms and procedures introduced under Circular 89/2026/TT-BTC apply from July 1, 2026.
What Is Vietnam PIT Finalization?
During the year, employers normally deduct PIT from salary and other taxable employment payments. However, the tax deducted each month may not equal the employee’s final annual liability.
Annual PIT finalization brings together:
Salary and wages received during the year;
Bonuses, commissions and allowances;
Employer-paid benefits;
Income paid by an overseas employer;
Income received from other organizations;
Permitted insurance contributions;
Personal and dependent deductions;
Other eligible deductions;
Vietnamese PIT already withheld;
Eligible foreign tax credits;
Tax previously paid directly by the employee.
The result may show that the employee has additional tax to pay, has overpaid and can request a refund, or has no remaining tax obligation.
PIT finalization is different from monthly or quarterly withholding. Withholding is a provisional collection during the year, while finalization establishes the final liability for the complete tax period.

Who Must Complete PIT Finalization in Vietnam?
Organizations paying taxable employment income and resident individuals receiving salary or wages generally have annual PIT finalization responsibilities.
For foreign employees, the first step is to confirm tax residency. Resident individuals are generally taxed on worldwide employment income and may be required to complete annual finalization. Non-residents are generally taxed at 20% on employment income connected with work performed in Vietnam and normally fall outside the annual finalization regime that applies to residents.
An individual’s nationality does not determine whether annual finalization is required. The employee’s residence status, income sources, withholding position and employment circumstances must be reviewed together.
A resident foreign employee will commonly need to file directly when the employee:
Receives taxable employment income from more than one organization and does not satisfy the conditions for employer authorization;
Receives salary or employment benefits directly from an overseas company;
Has income that was not fully included in the Vietnamese payroll;
Has additional tax payable after the annual calculation;
Wants to claim a PIT refund or offset an overpayment against a later period;
Is not working for the relevant income-paying organization when finalization is performed;
Claims special tax relief or deductions that require direct filing;
Ends an employment contract and prepares to leave Vietnam;
Needs to claim a foreign tax credit for tax paid outside Vietnam.
Having multiple sources of income does not always mean the employee must file directly. An exception may apply when the additional income satisfies the conditions discussed below.
When Is PIT Finalization Not Required?
Under the 2026 rules, a resident individual may not be required to finalize PIT in certain circumstances.
The Employee Has Overpaid but Does Not Request a Refund
An individual whose final tax liability is lower than the tax already paid may choose not to file if the individual does not request:
A refund of the overpaid amount; or
An offset of the overpayment against a subsequent tax period.
The employee should review the amount before deciding not to file. A material overpayment may justify completing the finalization and refund procedure.
Additional Income Meets the Incidental Income Exception
A resident employee may not have to finalize an additional income source when:
The employee has income from another payer;
The additional income averages no more than VND 15 million per month during the year;
The additional income has already been subject to 10% PIT withholding; and
The employee does not request finalization of that additional income.
If the employee chooses to file directly, the tax information system may support the aggregation of salary income reported by different payers. The employee should still check whether all income and withholding data are complete and accurate.
Can a Foreign Employee Authorize an Employer to Finalize PIT?
An eligible employee may authorize an income-paying organization to complete PIT finalization on the employee’s behalf.
Authorization may generally be available when the employee:
Has one source of salary or wage income;
Has an employment contract with a term of at least three months;
Is actually working for that organization when PIT finalization is performed; and
Otherwise satisfies the applicable authorization requirements.
The employee does not need to have worked for the company for the entire 12-month period.
Authorization may also be available when the employee has one principal employment source and additional income that qualifies for the incidental income exception: average additional income of no more than VND 15 million per month that has already been subject to 10% withholding.
Where an employee is transferred from an old organization to a new organization due to a merger, consolidation, division, separation, conversion of enterprise type or an internal transfer within the same corporate system, the new organization may be able to finalize PIT for income paid by both organizations. Supporting payroll information and withholding certificates should be transferred and reconciled.
Eligible employees should provide the employer with the PIT finalization authorization form, Form 08/UQ-QTT-TNCN, before the employer submits its finalization return.
Employer Authorization vs Direct Filing
Situation | Likely filing method |
One employer, contract of at least three months and still employed at finalization | Employer authorization may be available |
One principal employer plus qualifying incidental income already withheld at 10% | Employer authorization may be available |
Two or more material employment income sources | Direct filing is generally required |
Salary paid from overseas without full Vietnamese withholding | Direct filing is generally required |
Employee no longer works for the employer at the time of finalization | Direct filing is generally required |
Employee requests qualifying special tax relief | Direct filing is required |
Resident foreign employee ends employment and leaves Vietnam | Direct filing or authorization to another organization or individual |
Tax overpaid and no refund or offset is requested | Finalization may not be required |
The correct method depends on the employee’s complete facts. Employers should not accept authorization automatically without checking all income sources and the employee’s employment status.
What Changed for the 2026 PIT Finalization?
Vietnam’s revised Personal Income Tax Law took effect on July 1, 2026. However, the provisions concerning salary and employment income of resident individuals apply from the 2026 tax year.
This means the 2026 annual calculation must reflect the new rules, including:
A personal deduction of VND 15.5 million per month;
A dependent deduction of VND 6.2 million per dependent per month;
A five-bracket progressive tax table ranging from 5% to 35%;
New requirements concerning certain deductions for eligible healthcare and education expenses;
A VND 5 million payment threshold for mandatory 10% withholding on qualifying short-term or non-contractual payments;
Updated annual finalization and authorization rules.
Income and PIT already declared before July 1, 2026 generally do not need to be re-declared for each prior month or quarter solely because the new rules became effective. Necessary adjustments are made through the 2026 annual finalization.
This makes payroll reconciliation especially important for 2026. Employers should verify that calculations for the entire tax year are aligned with the rules applicable to resident employment income for 2026.
Vietnam PIT Finalization Deadlines
Deadline for Employers and Income-Paying Organizations
The annual PIT finalization return is generally due by the last day of the third month following the end of the tax year.
For an organization using the calendar year, the expected deadline for the 2026 finalization is:
March 31, 2027
Employers should collect authorization forms and reconcile payroll information before this date.
Deadline for Individuals Filing Directly
A resident individual filing PIT finalization directly generally has until the last day of the fourth month following the end of the calendar year.
For the 2026 tax year, the nominal statutory date is:
April 30, 2027
Because April 30 is a Vietnamese public holiday, the operational deadline may move to the next working day under the applicable deadline rules. Taxpayers should confirm the official 2027 working and holiday calendar before filing.
First Tax Year Based on 12 Consecutive Months
A foreign individual may be present in Vietnam for fewer than 183 days during the first calendar year but reach 183 days during 12 consecutive months from the first arrival date.
In that situation, the first tax period may be based on the relevant 12 consecutive months. The finalization deadline is generally the last day of the fourth month following the month in which that first 12-month period ends.
Deadline for Foreign Employees Leaving Vietnam
A resident foreign employee ending an employment contract in Vietnam must finalize PIT before leaving the country. Under the 2026 rules, the filing should also occur no later than 45 days after the employment contract ends.
If the employee cannot personally complete the procedure before departure, the employee may authorize the employer or another organization or individual to perform the finalization. The employee remains responsible for the resulting tax obligation.
Employers should begin departure finalization before the employee’s last working day rather than waiting until the planned departure date.
Documents Required for Vietnam PIT Finalization
The exact documents depend on the employee’s income sources, residence position, deductions and filing method.
Documents for an Individual Filing Directly
A typical file may include:
Form 02/QTT-TNCN: PIT finalization return for a resident individual receiving salary or wage income;
Form 02-1/BK-QTT-TNCN: dependent deduction appendix, where applicable;
Copies of PIT withholding certificates issued by income-paying organizations;
Bank documentation for tax paid outside Vietnam when a foreign tax authority does not issue a tax payment certificate;
Documents confirming income paid by an overseas employer, international organization, embassy or consulate;
Documents supporting eligible charitable or humanitarian contributions;
Documents supporting eligible healthcare and education deductions;
Information concerning the taxpayer’s bank account when a refund is requested;
Employment contracts, assignment letters and salary statements where required to reconcile income;
Passport and entry or exit information where the tax residence period must be verified;
Supporting documents for dependents that are not already available to the tax authority through connected government databases.
Where a document is issued overseas, Vietnamese translation, certification, consular legalization or another verification process may be required depending on the document and the tax authority’s request.
Documents for Employer-Authorized Finalization
An employer should normally maintain:
Form 08/UQ-QTT-TNCN: authorization for PIT finalization;
Payroll records for the entire tax year;
Details of taxable salary, bonuses and benefits;
PIT withholding and payment information;
Tax identification information;
Dependent registration information;
Records of overseas compensation or salary recharges;
Withholding certificates received from a former employer where an eligible corporate transfer has occurred;
Supporting documents for relevant deductions.
Under Circular 89/2026/TT-BTC, employers generally use:
Form 05/QTT-TNCN;
Form 05-1/BK-QTT-TNCN;
Form 05-2/BK-QTT-TNCN; and
Form 05-3/BK-QTT-TNCN.
The applicable appendices depend on the employees and income reported.
How to Complete Vietnam PIT Finalization
Step 1: Confirm Tax Residency
Determine whether the employee is a Vietnamese tax resident or non-resident for the relevant period.
Review:
Days physically present in Vietnam;
Registered or regular residence;
Lease arrangements;
Evidence of tax residence in another country;
The applicable double taxation agreement;
The first 12-month period from the initial arrival date.
Do not determine residency solely from the work permit, visa or nationality.
Step 2: Identify the Correct Tax Period
Most resident employees use the calendar year. However, a foreign employee’s first tax period may be based on 12 consecutive months when the individual does not reach 183 days in the first calendar year but reaches the threshold during the first 12 months in Vietnam.
The correct tax period affects income aggregation, deductions and the filing deadline.
Step 3: Collect Worldwide Employment Income
For a resident foreign employee, review employment income paid both inside and outside Vietnam.
Potential items include:
Local salary;
Overseas salary;
Bonuses;
Commissions;
Housing benefits;
School fees;
Tax reimbursements;
Insurance paid by the employer;
Relocation allowances;
Stock-based compensation;
Benefits provided by a parent or group company.
The bank account receiving the payment does not determine whether income must be reported in Vietnam.
Step 4: Reconcile PIT Already Withheld
Compare payroll records and withholding certificates with the income and PIT information recorded by the Vietnamese tax system.
Errors commonly arise when:
The employee’s tax identification information is incorrect;
An employer reports income under the wrong taxpayer;
Overseas income is missing;
A former employer has not issued a withholding certificate;
The amount withheld differs from the amount reported or paid;
Dependent information has not been updated.
Any discrepancy should be addressed before the final return is filed.
Step 5: Determine Whether Authorization Is Available
Check the employee’s contracts, income sources and employment status.
If the authorization conditions are satisfied, the employee should submit Form 08/UQ-QTT-TNCN to the employer before the employer completes its annual finalization.
If the conditions are not satisfied, the employee should file directly.
Step 6: Recalculate the Annual Liability
Calculate total taxable employment income for the relevant tax period and subtract eligible amounts, which may include:
Mandatory insurance contributions;
The personal deduction;
Properly supported dependent deductions;
Permitted retirement or insurance contributions;
Eligible charitable and humanitarian contributions;
Eligible healthcare and education expenses;
Other deductions permitted by law.
Apply the progressive resident rates to annual taxable income and compare the result with PIT already withheld or paid.
Where foreign tax has been paid on income also taxable in Vietnam, a foreign tax credit may be available subject to the applicable limits, supporting documents and any relevant tax treaty.
Step 7: Submit the Return to the Correct Tax Authority
For individuals with employment income from two or more sources, the competent authority is generally the tax authority directly managing the organization that paid the largest amount of income during the year.
If two largest income sources are equal, the individual may generally select one of the corresponding tax authorities.
An individual with one income source who files directly generally submits to the authority managing the income-paying organization. An individual who is no longer working for any payer at the time of finalization may be required to file with the authority responsible for the individual’s place of residence.
Electronic filing may be completed through the official electronic tax system or eTax Mobile where the relevant function is available.
Step 8: Pay Additional Tax or Request a Refund
If the annual liability exceeds the amount already paid, the outstanding amount should be paid by the applicable deadline.
If tax has been overpaid, the employee may:
Request a refund; or
Request that the overpayment be offset against a later tax obligation.
A refund may be delayed if withholding information, taxpayer identification data, bank details or employer declarations do not match the tax authority’s records.
Employees With Multiple Income Sources
Multiple-income cases are among the most common causes of incorrect PIT finalization.
An employee may receive:
Salary from a Vietnamese employer;
Income from a former Vietnamese employer;
Overseas salary from a parent company;
Director fees;
Consulting or service payments;
Bonuses paid after an employment contract ends;
Short-term payments already subject to 10% withholding.
The employee should not assume that every payer has access to the complete income picture.
When two or more material sources must be included, direct filing is generally required. The income should be aggregated and the progressive annual rates applied to the final taxable amount.
The incidental income exception should only be used when all conditions are satisfied, including the VND 15 million monthly average limit and prior 10% withholding.
Overseas Salary and Foreign Tax Credits
A Vietnamese tax resident is generally taxable on worldwide employment income. Therefore, salary paid by a foreign company may still need to be included in the Vietnamese return.
The employee should obtain:
Overseas payroll statements;
Confirmation of gross salary and benefits;
Evidence of foreign tax withheld or paid;
Bank payment records where appropriate;
Assignment agreements;
A breakdown of income connected with work inside and outside Vietnam;
Evidence supporting any claimed foreign tax credit.
Foreign tax paid is not automatically refunded or fully credited in Vietnam. The allowable credit is generally limited and must be supported by adequate documents. The relevant double taxation agreement should also be reviewed.
Departure PIT Finalization for Foreign Employees
Departure finalization requires early coordination between the employee, local employer, overseas employer, payroll provider and immigration team.
Before the employee leaves Vietnam, the employer should confirm:
The expected last working day;
The planned departure date;
The employee’s final residence status;
Local and overseas income up to the end of the assignment;
Final bonus and benefit payments;
Remaining PIT liabilities;
Availability of withholding certificates;
Whether the employee will file directly or appoint a representative;
How a later refund or additional assessment will be handled.
An employee who authorizes another party remains responsible for the accuracy of the information and the resulting tax obligation.
Where bonuses or other employment payments will be made after departure, the employer should determine how those amounts will be reported and whether an additional or amended filing may be necessary.
Employer Checklist for PIT Finalization
Before filing, employers should:
Identify all employees who received taxable income during the year.
Separate resident and non-resident employees.
Determine which employees are eligible to authorize finalization.
Collect Form 08/UQ-QTT-TNCN from eligible employees.
Reconcile local payroll with overseas payroll and salary recharge data.
Review taxable benefits, including housing and employer-paid expenses.
Verify tax identification and personal information.
Check dependent registrations and deduction periods.
Reconcile tax withheld, declared and paid.
Issue withholding certificates to employees filing directly.
Review departing foreign employees before their final working day.
Submit the return and applicable appendices by the deadline.
Retain payroll, authorization and supporting documents for inspection.
Common PIT Finalization Mistakes
Assuming Monthly Withholding Completes the Tax Obligation
Monthly deductions are provisional. Annual income, deductions and actual residence status may produce a different final liability.
Excluding Salary Paid Outside Vietnam
A resident employee may be taxable on worldwide employment income, including salary paid directly to an overseas account.
Accepting Authorization Without Checking Other Income
An employer should confirm that the employee satisfies all authorization conditions before including the employee in the employer’s finalization return.
Using the Old Incidental Income Threshold
Under the 2026 rules, the relevant additional income threshold is an average of no more than VND 15 million per month, provided the income has already been withheld at 10% and the employee does not request finalization of that income.
Applying the Wrong Tax Period
A foreign employee’s first tax period may be based on 12 consecutive months rather than the first calendar year.
Filing Departure Finalization Too Late
Waiting until the employee has left Vietnam can make it difficult to obtain signatures, foreign payroll information and supporting documents.
Missing Overseas Tax Evidence
A foreign tax credit can be challenged if the employee cannot demonstrate the amount of foreign income and tax paid.
Failing to Check Tax-System Data
Incorrect taxpayer information or employer reporting may cause delays, refund problems or inconsistent income records.

Frequently Asked Questions
Is Vietnam PIT finalization mandatory for every foreign employee?
No. Annual finalization generally applies to resident individuals, but exceptions may apply. Non-residents are generally taxed through withholding, while a resident with an overpayment may choose not to file if no refund or offset is requested.
Can a foreign employee authorize the employer to finalize PIT?
Yes, if the employee satisfies the authorization conditions. The employee generally needs one principal employment income source, a contract of at least three months and ongoing employment with the organization when finalization is performed.
Can an employee authorize the employer after changing jobs?
Generally, an employee who is no longer working for the former employer at the time of finalization cannot authorize that employer. A special rule may apply to transfers within the same corporate system or qualifying corporate reorganizations.
What if the employee has income from two companies?
Direct filing is generally required when the employee has two or more material employment income sources. An exception may apply to qualifying additional income averaging no more than VND 15 million per month that has already been withheld at 10%.
What form is used for direct PIT finalization?
A resident individual filing directly uses Form 02/QTT-TNCN. Form 02-1/BK-QTT-TNCN is also used when dependent deductions are reported.
What form is used to authorize the employer?
An eligible employee uses Form 08/UQ-QTT-TNCN to authorize the income-paying organization to complete finalization.
When is the 2026 PIT finalization deadline?
An income-paying organization generally files by the last day of the third month after year-end. A resident individual filing directly generally files by the last day of the fourth month after the calendar year.
