Vietnam Personal Income Tax 2026: Complete Guide for Expats

The Essential Overview

Vietnam taxes its residents on worldwide income at progressive rates of 5% to 35%. Non-residents pay a flat 20% on Vietnam-sourced income only. The critical threshold is 183 days - cross it in any calendar year and you become a tax resident.

In January 2026, Law No. 109/2025/QH15 brought Vietnam's most significant personal income tax reforms since 2012. If you have been relying on older guides, much of what they say is now outdated.

Tax Residency: The 183-Day Rule

You are a Vietnamese tax resident if you spend 183 days or more in Vietnam within:

• A single calendar year (January 1 to December 31), OR
• Any consecutive 12-month period starting from your first entry date

Days do not need to be consecutive. Brief exits do not reset the clock.

Non-Residents

If you spend fewer than 183 days in a year:

• Only income sourced from Vietnam is taxed
• Flat rate: 20%
• No personal tax return required (employer withholds at source)

Tax Residents

If you spend 183+ days:

• Worldwide income is subject to Vietnamese PIT
• Progressive rates apply (see below)
• Annual tax return required

2026 Tax Rates for Residents

Vietnam uses a progressive bracket system applied to monthly employment income:

| Monthly Taxable Income (VND) | Approx. Monthly (USD) | Rate | |

|

|

| | Up to 5,000,000 | Up to $200 | 5% | | 5,000,001 - 10,000,000 | $200-400 | 10% | | 10,000,001 - 18,000,000 | $400-720 | 15% | | 18,000,001 - 32,000,000 | $720-1,280 | 20% | | 32,000,001 - 52,000,000 | $1,280-2,080 | 25% | | 52,000,001 - 80,000,000 | $2,080-3,200 | 30% | | Over 80,000,000 | Over $3,200 | 35% |

These are progressive brackets - you pay the lower rate on the portion of income falling in each band, not the top rate on everything.

What Changed in 2026

Law No. 109/2025/QH15 (effective January 1, 2026 for employment income) introduced:

• Raised personal deduction thresholds - the first increase since 2013, easing pressure on middle-income earners
• Clearer rules for remote/digital income - better sourcing guidance for income paid by overseas employers
• High-tech sector incentives - preferential treatment for qualifying technology professionals
• Updated dependent deduction amounts - revised upward for the first time in over a decade

Deductions That Reduce Taxable Income

Personal Deduction

Every tax resident receives a personal deduction reducing monthly taxable income. The 2026 reforms raised this amount - the exact figure will be confirmed by implementing decree. Monitor official announcements for the final number.

Dependent Deductions

Qualifying dependents (children under 18, dependent parents, disabled relatives) each reduce your monthly taxable income by a fixed amount per person.

Social Insurance Contributions

Mandatory contributions to Vietnamese social, health, and unemployment insurance are deductible if you are employed by a Vietnamese entity.

How Employment Income Is Taxed

Working for a Vietnamese Employer

Your employer withholds PIT monthly and remits it to the tax authority. You receive net income. Annual reconciliation is required by March 31 (employer) and April 30 (individual).

Working Remotely for a Foreign Employer

This is where it becomes complex:

If you are a tax resident (183+ days), you must declare and pay Vietnamese PIT on your worldwide employment income. The overseas employer does not withhold - you are responsible for self-assessment.

If you are a non-resident (under 183 days), income for work performed outside Vietnam is generally not Vietnam-sourced. However, if you are physically performing the work from Vietnam, the General Department of Taxation may argue the income is Vietnam-sourced.

The practical reality: most remote workers who carefully manage their days under 183 face very low enforcement risk. But this gray area is shrinking as Vietnam develops its international tax information exchange agreements.

Non-Employment Income

Business Income

Profits of a Vietnamese-registered company are subject to Corporate Income Tax at 20%. Dividends paid to foreign shareholders are then subject to a 5% withholding tax.

Investment Income

| Income Type | Rate | |

|

| | Dividends | 5% | | Bank interest | 5% | | Securities gains (per transaction) | 0.1% of sale value | | Real estate transfer | 2% of sale value |

Pension Income

Most overseas pension income of a Vietnamese tax resident is included in worldwide income. Whether it is actually taxable in Vietnam depends on your tax residency status and whether a tax treaty between Vietnam and your home country allocates that income to the source or residence country.

Tax Treaties

Vietnam has tax treaties with 80+ countries including the USA, UK, Australia, Germany, France, Japan, South Korea, and most EU nations.

Treaty provisions commonly:

• Prevent double taxation of the same income
• Allocate taxing rights between countries
• Reduce withholding tax rates on dividends and interest

Important: A tax treaty does not mean you pay zero tax - it means you do not pay the full rate in both countries. You typically claim a foreign tax credit in your home country for taxes already paid in Vietnam.

US Expats: Additional Obligations

Americans do not escape the IRS by living abroad.

Filing requirement: US citizens and green card holders must file a US tax return regardless of residency, if income exceeds the filing threshold (~$14,600 for singles in 2026).

Foreign Earned Income Exclusion (FEIE): Qualifying US expats can exclude approximately $120,000-130,000 of foreign earned income from US tax (2026 amount - indexed annually).

Foreign Tax Credit (FTC): Alternatively, claim a dollar-for-dollar credit for Vietnamese taxes paid against your US liability.

FBAR: If your Vietnamese bank accounts exceed $10,000 at any point in the year, file an FBAR (FinCEN 114) by April 15 (auto-extended to October 15).

FATCA Form 8938: Report foreign financial accounts exceeding $200,000 at year-end (or $300,000 at any point).

US expat taxes in Vietnam are genuinely complex. Most Americans here work with a specialist US expat tax firm in addition to managing their Vietnamese PIT obligations.

UK Expats: Key Considerations

UK residents are taxed on worldwide income. If you leave the UK and become non-UK resident under the Statutory Residence Test (SRT), your foreign income is generally not taxable in the UK.

Key points:

• The SRT has specific day-count rules - get formal advice on breaking UK residency before assuming you are no longer subject to UK tax
• UK-source pension income may remain taxable in the UK depending on treaty provisions
• ISA income is UK tax-free, but Vietnam may tax it if you are a Vietnamese tax resident

Filing Deadlines

| Obligation | Deadline | |

|

| | Employer monthly PIT withholding | By the 20th of the following month | | Annual employer PIT reconciliation | March 31 | | Individual annual PIT return | April 30 | | Self-employed quarterly PIT | 30th of month after quarter end |

How to Get a Tax Code

Foreign individuals earning income in Vietnam need a personal Tax Identification Number (Ma So Thue / MST).

Process:

1. Apply at the local Tax Department or through your employer
2. Provide passport, Vietnamese visa or TRC, and basic personal details
3. Processing time: 5-10 working days

Once issued, all Vietnam-sourced income must be declared under this code.

Common Mistakes Expats Make

1. Assuming e-visa status removes tax obligations - Tax residency depends on days spent, not visa type
2. Ignoring the worldwide income rule - Tax residents must declare all income globally, not just Vietnamese income
3. Missing self-assessment obligations - Remote workers paid by foreign employers must file themselves; no one withholds for them
4. Not tracking days carefully - The 183-day threshold is unforgiving; keep a travel log
5. Forgetting home country obligations - Paying Vietnamese PIT does not automatically reduce what you owe at home
