Do Foreigners Without Salaries in Vietnam Have to Pay Taxes? How to Comply and Avoid Double Taxation?

For foreigners living and working in Vietnam, understanding the local tax framework is an important part of meeting Personal Income Tax (PIT) obligations and managing cross-border income. Tax treatment depends on factors such as tax residency, the type and source of income, and whether a Double Taxation Agreement (DTA) applies.

This guide explains the key tax requirements for foreigners in Vietnam, including tax residency rules, applicable PIT rates, taxable and exempt income, tax deductions and the role of DTAs in addressing income that may be taxable in more than one jurisdiction. It also covers key compliance considerations and penalties for late or inaccurate tax filings.

Who Needs to Comply with Tax Obligations in Vietnam?

Tax obligations in Vietnam apply to all foreigners generating income within the country, regardless of whether they receive a salary or earn through other means. The tax framework distinguishes between:

• Tax Residents: Individuals staying in Vietnam for 183 days or more within either a calendar year or 12 months from their arrival date. These residents are subject to progressive tax rates ranging from 5% to 35% on their worldwide income.

• Non-Tax Residents: Those staying less than 183 days, are subject to a flat 20% tax rate on their Vietnam-sourced income.

Understanding Double Taxation Agreements

A cornerstone of Vietnam's international tax framework is its extensive network of Double Taxation Agreements (DTAs).  As of December 2025, Vietnam had signed 81 DTAs, of which 77 were in effect. These agreements can determine how specific categories of cross-border income are taxed and may provide relief from double taxation, subject to the relevant treaty and applicable conditions.

• Eliminating or reducing the burden of double taxation

• Providing clear frameworks for tax liability allocation between countries

• Enhancing Vietnam's attractiveness for foreign investment

• Facilitating international trade and cross-border business activities

The significance of DTAs cannot be overstated in today's globalised economy. Based on OECD Model Tax Convention principles, these agreements establish clear guidelines for:

• Determining tax residency status

• Defining various categories of taxable income

• Setting provisions for dispute resolution

• Offering potential tax relief through exemptions or reduced rates

Why Understanding These Regulations Matters?

Compliance with Vietnamese tax regulations is essential for several reasons:

1. Legal Compliance: Violations of tax regulations can result in penalties and legal complications that may affect your ability to continue working or doing business in Vietnam.

2. Financial Planning: Understanding your tax obligations helps you plan better, especially given Vietnam's significant allowable deductions.

3. Investment Benefits: Knowledge of DTAs can help you manage your tax position, and avoid unnecessary double taxation on your international income.

4. Business Operations: For those running businesses or investing in Vietnam, understanding tax implications is crucial for making informed business structure and operations decisions.

Do Foreigners Without Salaries Need to Pay Taxes?

Foreigners without employment income in Vietnam may still need to pay taxes if they receive other forms of taxable income as defined by Vietnamese tax regulations. Even without salary income, foreigners are subject to Personal Income Tax (PIT) on various types of income.

These include business income when yearly revenue exceeds VND 100 million, investment income such as interest or dividends (except deposit interest from banks and credit institutions), and earnings from capital transfers through share exchanges or other forms. They must also pay taxes on income from real estate transactions unless it is their only property or a transfer between family members.

Additionally, foreigners must pay taxes on prize winnings, income from copyright or royalties, earnings from franchising, and any inheritances or gifts in the form of stocks, capital contributions, real estate, or other assets that require registration of ownership or use rights. This comprehensive taxation framework ensures that all significant forms of income are properly regulated and taxed, regardless of the individual's employment status.

Tax Exemptions and Foreign Currency Conversion

Vietnamese tax law does provide several exemptions. Foreigners, like Vietnamese citizens, are not required to pay tax on:

• Overseas remittances

• Interest earned from life insurance contracts

• Compensation received under life or non-life insurance contracts

• Income from agricultural activities, including salt-making, cultivation, forestry, or fisheries

• Income from real estate transfers between family members

• Income from the transfer of a single residential house or land plot
  
  

For tax calculation purposes, any taxable income received in foreign currency must be converted to Vietnamese Dong:

• Use the average trading exchange rate from the inter-bank foreign currency market, as published by the State Bank of Vietnam

• Apply the rate in effect on the date the income was received

This ensures consistent, fair taxation regardless of the currency the income was originally paid in.

In short: whether or not you draw a salary in Vietnam, most meaningful forms of income are taxable, with the specific exemptions covered above.

Tax Residency Status & Applicable Tax Rates in Vietnam

Vietnam's income tax (PIT) system distinguishes between tax residents and non-residents, with different tax implications for each status:

• Tax Residents: Subject to PIT on worldwide taxable income, regardless of where it is paid or received

• Non-Residents: Subject to PIT only on Vietnam-sourced income, with consideration given to applicable double taxation agreements (DTAs)

Tax Rates for Residents

1. Employment Income (Progressive Tax Rates)

2. Business Income Rates

Individuals earning business income below VND 100 million per calendar year are exempt from PIT.

3. Other Income Types for Residents

Tax Rates for Non-Residents

Tax Residency Status

A person is considered a tax resident if they are:

• Present in Vietnam for 183 days or more, or

• Have a permanent residence in Vietnam

The residency status significantly impacts tax obligations in two main ways:

Income Tax Rates

1. Residents:

• Subject to progressive tax rates from 5% to 35%

• The tax applies to worldwide income (both Vietnam and foreign-sourced)

• Eligible for personal deductions

2. Non-residents:

• Fixed 20% tax rate on Vietnam-sourced salary/wages

• Only taxed on income generated within Vietnam

• Not eligible for personal deductions

How to Avoid Double Taxation (DTA – Double Taxation Agreements)?

Vietnam's Double Taxation Avoidance Agreements:

Double Taxation Agreements (DTAs) are crucial international treaties designed to prevent the same income or property from being taxed twice. These agreements, signed between the two countries, aim to foster economic cooperation and ensure fair taxation for individuals and businesses operating internationally. Vietnam has actively pursued DTAs to encourage cross-border activity and provide clarity for taxpayers.

Beyond bilateral agreements, Vietnam participates in multilateral tax arrangements like the ASEAN-China Free Trade Agreement (ACFTA). The ACFTA Decree 118/2022/ND-CP, effective December 30, 2022, reinforces preferential import duty commitments under the ACFTA for 2022-2027. Vietnam is also committed to international tax standards, notably measures against Base Erosion and Profit Shifting (BEPS) through its involvement in the Global BEPS Forum.

Methods to Avoid Double Taxation:

Vietnam employs one or a combination of three methods to mitigate double taxation, as outlined in its treaties:

• Tax Deduction Method: Vietnamese residents whose income is taxed in another treaty country can deduct the tax paid from their Vietnamese tax liability.

• Fixed Tax Deduction Method: For Vietnamese residents with income taxed abroad, a fixed tax amount is deducted from their Vietnamese tax liability.

• Indirect Tax Credit Method: Vietnamese residents receiving income from a company in the other treaty country can deduct indirect taxes paid in that country from their Vietnamese tax liability. This deduction is capped at the amount of tax owed in Vietnam. If a treaty does not address indirect tax credits, but Vietnamese law does, the domestic law will apply.

How Do DTAs Work?

In Vietnam, DTAs impact both corporate and personal income tax. They are applied as follows:

• DTAs supersede domestic tax laws when a direct conflict arises.

• Domestic tax laws prevail when the relevant tax obligations in the DTA do not exist in Vietnam, or when the DTA tax rates exceed domestic rates. For instance, if the other country imposes a tax Vietnam does not recognise, Vietnam's tax laws will apply.

• DTAs do not affect the rights and immunities of diplomatic and consular missions, as protected by international treaties to which Vietnam is a signatory.

Utilising DTAs Effectively

DTAs between Vietnam and ASEAN member states offer a valuable mechanism to reduce or eliminate double taxation for individuals and businesses engaged in cross-border activities. However, simply knowing these agreements exist is insufficient. A strategic approach is essential to maximise their benefits.

Understanding the DTA Landscape

The first step is identifying the relevant DTA. This depends on your residency status and the source of your income. Vietnam and the respective ASEAN countries should provide information on their DTAs. Reviewing the DTA text is crucial, though the legal language can be complex. Consulting a tax professional specialising in Vietnamese tax law and DTAs is highly recommended to interpret the provisions relevant to your situation.

Claiming Treaty Benefits

Claiming treaty benefits might require gathering documentation like residency certificates, tax residency certificates, or contracts detailing your income. Some DTAs offer exemptions from specific taxes or reduced withholding tax rates. The application process may involve submitting documentation to Vietnamese tax authorities. A tax professional can guide you through the correct procedures.

Even with treaty benefits, filing tax returns in both Vietnam and the relevant ASEAN countries is essential. However, you may be able to claim tax credits for taxes paid in the other country.

Optimising Tax Efficiency with Professional Guidance

Understanding residency rules is critical, as DTAs often have specific criteria. A tax professional can clarify these rules and ensure proper classification to maximise treaty benefits. DTAs often include anti-abuse clauses. A tax professional can help structure your cross-border activities to comply with these clauses and optimise tax efficiency.

Staying updated on DTA changes is also important. Consulting a tax professional ensures you are aware of any revisions that may affect your eligibility.

Benefits Realised

Effectively using DTAs offers numerous advantages, including a reduced tax burden, simplified compliance, and enhanced investment opportunities. DTAs can lower tax liabilities, especially for cross-border income. Understanding DTAs also streamlines Vietnamese tax filing and makes cross-border ventures within ASEAN more attractive.

Penalties for Non-compliance in Vietnam

a. Penalties for Late Tax Filing

As outlined in Article 13 of Decree 125/2020/ND-CP, individuals who fail to file their personal income tax returns on time may face the following consequences:

1. Warning for Minor Delays: If the tax return is submitted 1-5 days late and there are mitigating circumstances, a warning may be issued.

2. Monetary Fines: For longer delays, fines ranging from 2 to 25 million VND can be imposed, depending on the length of the delay.

In addition to these penalties, taxpayers must pay the full amount of tax due, along with any late payment fees.

b. Importance of Timely and Accurate Tax Filing

Filing taxes on time and accurately is crucial for several reasons. It ensures compliance with legal requirements, helps avoid penalties and interest charges for late payments, and reduces the risk of tax audits. Additionally, timely tax filing contributes to maintaining financial credibility and supports the national budget, which funds essential public services and socio-economic development.
