How Foreigners Can File Personal Income Tax Returns in Vietnam

Filing personal income tax (PIT) in Vietnam is a legal obligation for many foreigners working or earning income in the country. Whether employed by a local company, investing in Vietnamese assets, or receiving rental income, foreign individuals are subject to specific tax rules and deadlines. In most cases, employers assist with filing, but it’s still essential to understand how the process works to ensure accurate reporting and avoid penalties.

Knowing your obligations ahead of time helps prevent errors and unnecessary complications with the tax authorities.

Understanding your tax residency status

Establishing tax residency status is a critical first step in navigating Vietnam’s income tax system. The classification between resident and non-resident shapes the scope of tax obligations. A foreign national is considered a tax resident if they stay in Vietnam for at least 183 days within 12 months or have a registered permanent residence with the local authorities.

This distinction carries significant consequences. Tax residents are subject to tax on their global income, whereas non-residents are only taxed on income earned within Vietnam. Beyond the tax base, residency status also influences applicable tax rates, deductible items, and filing requirements.

Alongside these rules, Vietnam has signed over 80 double taxation avoidance agreements (DTAAs), which may reduce or eliminate tax liabilities on various types of cross-border income.

Clarifying residency status and reviewing relevant treaty provisions are, therefore, essential to fulfilling tax obligations accurately.

Types of income subject to personal income tax

Foreigners in Vietnam are typically liable to pay tax on income such as salaries, business profits, capital gains, dividends, rental income, and royalties. Employment income remains the most common category, but investment-related income is also taxable if sourced locally. Vietnam does not generally tax foreign-sourced income for non-residents.

However, residents with global income, including from overseas investments, may be subject to taxation unless exempted by a tax treaty. Allowances such as housing, transportation, and relocation support may also be taxable unless specifically exempt.

Tax rates applicable to foreign individuals

For tax residents, Vietnam applies a progressive tax rate ranging from 5 percent to 35 percent based on annual income brackets. Non-residents are subject to a flat 20 percent rate on income sourced from within the country. Investment income, such as dividends, interest, and capital gains, may be taxed at separate fixed rates. For example, capital gains from securities are generally taxed at 0.1 percent on the gross transfer value.

It is important to verify the applicable rate and whether your income qualifies for special treatment under a DTAA.

Preparing the required documents for filing

Before filing your PIT return, you will need to gather key documents such as your Tax Identification Number (TIN), proof of income, and supporting documents for any deductions you wish to claim. For employees, this may include employment contracts, monthly payslips, and social insurance contribution records.

If you are self-employed or earning from multiple sources, proper recordkeeping is essential. Taxpayers must also use the correct forms, such as Form 02/QTT-TNCN for annual finalization, and ensure that all personal information is up to date.

If a refund is expected, valid bank account details must also be provided.

Step-by-step process to file your personal income tax return

Filing your PIT as a foreigner in Vietnam involves a few clear steps that help ensure compliance and avoid mistakes.

Many foreign employees will have their PIT finalized by their employer, especially if they have a single source of income. Still, it is essential to monitor the process and ensure that all income and deductions have been reported correctly.

Registering for a Tax Identification Number

Register for a Tax Identification Number (TIN) if you have not already done so. This is typically arranged through your employer, but individuals can also register directly with the local tax office.

Collecting income records and deduction documents

Gather all relevant income documentation, including payslips, contracts, rental or investment income statements, and receipts for allowable deductions such as insurance contributions or dependents.

Completing the PIT finalization form

Download or access the PIT finalization form, most commonly Form 02/QTT-TNCN, and fill it out accurately. You can also access this through the eTax online portal.

Submitting the tax return

Submit the completed form to the local tax authority or file online through the General Department of Taxation’s eTax portal. If your employer is assisting with your return, confirm that it has been filed on your behalf.

Paying outstanding tax

Pay any outstanding tax due via bank transfer or through Vietnam’s approved online payment gateways. Keep the payment receipt as proof.

Retaining documentation and monitoring refunds

Retain a copy of your filed return and all supporting documents. If you are entitled to a refund, monitor your registered bank account for disbursement.

Filing deadlines and penalties for late submission

Vietnam’s tax year aligns with the calendar year, and personal income tax returns must be finalized by March 31 of the following year. Late submissions may result in administrative penalties and interest charges on any unpaid tax. For foreign nationals preparing to depart Vietnam permanently, an exit tax clearance may be required before leaving the country.

Early preparation is recommended, particularly in cases involving complex income structures or multiple sources of income, to ensure accurate and timely compliance.

Avoiding common filing mistakes

Many foreigners encounter challenges due to misclassifying their residency status or underreporting income. Others overlook allowances or submit incomplete documentation. In some cases, relying solely on employers for filing may lead to errors if the provided information is outdated.

Another frequent issue is failing to update personal information, such as address or employment status with the tax authority, which can delay processing.
