Vietnam Personal Income Tax for Expats: The Complete 2026 Guide

The short answer

Expats in Vietnam are taxed based on residency status, not nationality or visa type. Tax residents (present 183+ days in a calendar year or 12 consecutive months, or maintaining permanent accommodation in Vietnam) are taxed on worldwide income at progressive rates now running from 5% to 35% across five brackets under Vietnam’s new Personal Income Tax Law (Law No. 109/2025/QH15), effective from 1 July 2026 with employment and business income provisions applying from the 2026 tax year. Non-residents are taxed at a flat 20%, but only on Vietnam-sourced income.

Residency: the single most important classification

An individual becomes a Vietnam tax resident if any of the following apply:

• Present in Vietnam for 183 days or more in a calendar year, or

• Present in Vietnam for 183 days or more across any rolling 12-month period from first arrival, or

• Maintains a registered permanent residence or a qualifying leased dwelling in Vietnam

Any one of these conditions independently triggers resident status — meeting just one is enough. This classification determines everything else: whether worldwide income is taxable in Vietnam, which rate structure applies, and what deductions are available.

What changed under Law 109/2025/QH15

• PIT brackets simplified from seven to five, effective 1 January 2026, for tax resident progressive rates (5% to 35%)

• Personal deduction increased to VND 15.5 million per month (up from the prior VND 11 million)

• Dependent deduction increased to VND 6.2 million per month per registered dependent (up from VND 4.4 million)

• Expanded exemptions, including a five-year PIT holiday for qualifying high-tech talent

• Extended coverage to income from digital platforms, e-commerce, and certain digital asset transactions

• Detailed implementing guidance for some measures (education/healthcare deductions, gold transaction thresholds) awaits further decrees and circulars — taxpayers should apply the law conservatively until these are issued

Deductions available to resident expats

• Personal deduction: VND 15.5 million/month

• Dependent deduction: VND 6.2 million/month per registered dependent

• Mandatory social, health, and unemployment insurance contributions

• Approved charitable donations, with proper documentation

Filing obligations and deadlines

• Employer-managed PIT is generally withheld monthly, with annual finalization due by 30 April (or the next working day) for the prior tax year

• Individuals with multiple income sources, or who file independently, must complete their own annual finalization

• Foreign workers ending their Vietnam contract must settle PIT within 45 days of their exit date, either self-filed or through employer authorization

• Non-resident foreigners who don’t meet the 183-day test and have no continuing Vietnam income source generally aren’t required to file an annual finalization, unless seeking a refund

Where expats most often get this wrong

1. Assuming a work permit or visa type determines tax status — it doesn’t; only the residency tests matter.

2. Not tracking days in Vietnam carefully, especially for those who travel regionally for work and inadvertently cross the 183-day threshold mid-year.

3. Missing the double taxation dimension for US citizens specifically — with no US-Vietnam tax treaty in force, planning around the Foreign Tax Credit and Foreign Earned Income Exclusion needs to be more deliberate (see our US-Vietnam Tax Treaty: Why There Is (Still) No Treaty in Force - and What US Businesses and Individuals Should Do Instead).

4. Missing the pre-departure filing deadline, which carries fines of up to VND 25 million plus daily interest on unpaid tax.
