Expat Tax Services Vietnam help foreign employees, expatriate managers, and international companies manage personal income tax (PIT) obligations in Vietnam. Expatriates may receive salary from a Vietnamese company, an overseas employer, or several related companies. Therefore, their tax position can require a more detailed review than that of a local employee. Vietnam’s PIT rules changed significantly for the 2026 tax year. The new Personal Income Tax Law applies from July 1, 2026, while the rules on salary and wage income of resident individuals apply from the 2026 tax year. In addition, Decree 253/2026/ND-CP and Circular 87/2026/TT-BTC provide detailed guidance for PIT administration and calculation. Therefore, companies employing expatriates should review their payroll, benefits, tax residency, and reporting process carefully. At the same time, foreign employees should understand their own tax obligations before starting work, changing jobs, or leaving Vietnam.

I. What Are Expat Tax Services Vietnam?

1.1 Understanding Expat Tax Services

Expat tax services cover tax support for foreign individuals who work, live, or earn taxable income in Vietnam. Depending on the individual’s situation, the service can include tax registration, PIT calculation, tax withholding, annual tax finalization, tax residency review, and support with tax documents.

For example, an expatriate may sign an employment contract with a Vietnamese company while receiving part of the salary from an overseas parent company. Another employee may receive housing, school fees, insurance, relocation costs, or other benefits as part of an international assignment. Therefore, the tax review should cover the entire compensation package rather than only the monthly salary paid in Vietnam.

Common expat tax services can include:

• Personal tax code registration
• Tax residency assessment
• Monthly PIT calculation and review
• Tax withholding support
• Annual PIT finalization
• Tax gross-up calculations
• Tax equalization support
• Foreign income review
• Foreign tax credit review
• Tax compliance when leaving Vietnam

As a result, professional tax support can help employers and expatriates maintain consistent records throughout the assignment.

1.2 Who May Need Expat Tax Services?

Expat tax services can apply to many types of foreign employees. In particular, multinational companies often need tax support when they transfer employees to Vietnam for short-term or long-term assignments.

The service may be relevant to:

• Foreign employees working for Vietnamese companies
• Foreign managers and directors
• Expatriates assigned by overseas parent companies
• Foreign employees receiving salary from overseas
• Foreigners working for more than one organization
• Foreign employees receiving employment benefits in Vietnam
• Expatriates ending their Vietnam assignments

Therefore, the correct tax approach depends on the employee’s actual work, income, and residence arrangements.

II. PIT Rules for Expatriates in Vietnam

2.1 Taxable Employment Income

Vietnamese PIT can apply to salary, wages, and other taxable employment income. For resident individuals, the current rules calculate PIT based on taxable employment income without distinguishing where the income is paid.

This point is especially important for expatriates. For example, a foreign employee may receive salary from a Vietnamese company while the overseas parent company pays a bonus or other employment benefit. The company should therefore review the complete compensation arrangement when calculating Vietnamese PIT.

Employment-related items may include:

• Basic salary
• Bonuses
• Allowances
• Housing benefits
• Education benefits
• Insurance benefits
• Relocation benefits
• Other taxable employment benefits

However, not every benefit automatically creates taxable income. Therefore, each payment or benefit should be reviewed under the current Vietnamese rules.

2.2 New PIT Rules From 2026

The 2026 tax year introduces important changes for resident individuals with salary and wage income. The new law reduces the progressive PIT schedule from seven brackets to five brackets. It also increases the family circumstance deduction to VND 15.5 million per month for the taxpayer and VND 6.2 million per month for each dependent.

The five progressive tax brackets for resident employment income are:

• Up to VND 10 million: 5%
• Over VND 10 million to VND 30 million: 10%
• Over VND 30 million to VND 60 million: 20%
• Over VND 60 million to VND 100 million: 30%
• Over VND 100 million: 35%

Therefore, companies should update their expatriate payroll systems and tax calculation models for the 2026 tax year rather than continuing to use the previous seven-bracket system.

2.3 PIT Withholding for Foreign Employees

Employers generally need to withhold PIT when they pay taxable employment income. The current rules also provide specific treatment for foreign individuals working in Vietnam.

For a foreign individual, the withholding method depends in part on the person’s period of work in Vietnam. The current guidance distinguishes foreign employees who work in Vietnam for 183 days or more from those who work for fewer than 183 days in the tax year.

Therefore, employers should review the employee’s work period and tax status before deciding how to calculate and withhold PIT.

III. Tax Residency for Expatriates

3.1 Resident and Non-Resident Status

Tax residency is one of the most important issues in expatriate tax planning. A foreign employee’s tax position can differ depending on whether the person qualifies as a Vietnamese tax resident or non-resident.

The company should therefore review the expatriate’s time in Vietnam, residence arrangements, employment contract, and other relevant information. In addition, the company should consider any applicable tax treaty when the employee also has tax connections with another country.

For example, an expatriate may initially expect to be a non-resident because the employee plans to stay in Vietnam for only part of the year. However, the employee’s actual presence and residence conditions may produce a different result.

3.2 The 183-Day Test

The 183-day test is particularly important for foreign employees. The current rules use the individual’s presence in Vietnam and other residence conditions when determining tax residency.

Therefore, companies should keep accurate entry and exit records. These records can help establish the employee’s actual period in Vietnam and support the tax residency assessment.

Furthermore, the 183-day threshold should not be treated as the only factor in every case. Residence arrangements and applicable rules can also affect the final assessment.

3.3 Tax Residency and Foreign Income

For resident individuals, Vietnam’s PIT rules apply to employment income without distinguishing where the income is paid.

As a result, an expatriate who receives salary from an overseas employer may still have Vietnamese PIT obligations. This situation commonly occurs when a foreign employee remains on the payroll of a foreign parent company during a Vietnam assignment.

Therefore, employers should review both Vietnamese and overseas payroll records when preparing an expatriate’s tax calculation.

IV. Expatriate Tax Compliance and Services

4.1 Personal Tax Code Registration

Foreign employees who have Vietnamese tax obligations need appropriate taxpayer registration. A personal tax code allows the tax authority to connect the individual’s income, tax payments, and tax filings with the correct taxpayer record.

The registration process can depend on how the expatriate receives income. For example, an employee may authorize a Vietnamese income-paying organization to register the tax information, while another individual may need to complete the process directly.

Therefore, companies should check whether the expatriate already has a Vietnamese tax code before submitting a new registration.

4.2 Monthly PIT Calculation

Monthly payroll is an important part of expatriate tax compliance. The employer should identify taxable salary and benefits, apply the correct deductions, and calculate the PIT that needs to be withheld.

In addition, the company should review changes during the year. For example, an expatriate may receive a bonus, move into company-provided housing, change employment status, or receive additional income from an overseas company.

As a result, payroll teams should update the tax calculation when the employee’s compensation changes.

4.3 Annual PIT Finalization

PIT finalization allows the taxpayer to compare the total tax liability with the tax already withheld or paid during the relevant period.

For expatriates, the finalization can require a wider review because the employee may have changed employers, received foreign income, or worked in Vietnam for only part of the year.

The review may include:

• Total employment income
• Taxable benefits
• PIT already withheld
• Family deductions
• Dependent information
• Foreign income
• Tax residency
• Foreign tax paid, where relevant

Therefore, expatriates should keep their tax documents throughout the year instead of waiting until finalization.

V. Special Expatriate Tax Services

5.1 Tax Gross-Up Services

Many international employment contracts state that the company will pay the employee a net salary or bear certain Vietnamese tax costs. In this situation, the company may need a tax gross-up calculation.

A gross-up calculation starts with the agreed net amount and works backward to determine the related gross taxable income and PIT.

This process can become more complex when the employer also pays housing, insurance, school fees, or other benefits. Therefore, companies should include all relevant taxable items in the calculation.

5.2 Tax Equalization Services

Multinational companies may also use a tax equalization policy for expatriate assignments. Under this approach, the company compares the employee’s expected home-country tax position with the actual tax position created by the Vietnam assignment.

However, tax equalization remains an internal company policy. It does not replace Vietnamese PIT rules.

Therefore, the company should first calculate the employee’s Vietnamese PIT under current law. After that, it can apply its internal tax equalization policy to determine the employee’s final assignment adjustment.

5.3 Foreign Tax Credit Review

An expatriate may pay tax in both Vietnam and another country. In such cases, the company should review whether foreign tax can receive credit against Vietnamese PIT under the applicable rules.

The taxpayer may need supporting documents that prove the foreign tax payment. Therefore, expatriates should keep foreign tax returns, tax payment evidence, and other relevant documents.

Furthermore, the company should review the applicable tax treaty before applying a foreign tax credit.

VI. Expat Tax Services When Leaving Vietnam

6.1 Tax Finalization Before Departure

Leaving Vietnam can create additional tax compliance work for an expatriate. Foreign employees who end their employment should review their outstanding Vietnamese PIT before departure.

Current guidance states that a foreign resident who ends their employment contract in Vietnam must complete their PIT settlement before leaving Vietnam. The individual can complete the procedure directly or authorize another eligible party where the rules allow.

Therefore, companies should include tax finalization in their expatriate offboarding process.

6.2 Final Payroll and Tax Review

Before an expatriate leaves Vietnam, the employer should review the final salary, bonuses, taxable benefits, tax withheld, and other relevant income.

The company should also check whether the employee has outstanding tax obligations or potential tax refunds.

In addition, HR and accounting teams should make sure that the employee has the necessary tax documents for future reference.

6.3 Post-Departure Tax Support

Some expatriates may need tax support even after leaving Vietnam. For example, the employee may need to complete a tax finalization, respond to a tax authority request, or provide additional documents after returning to their home country.

Therefore, companies should keep expatriate tax records in an organized form. This approach makes it easier to respond to later tax questions.

VII. Conclusion

Expat Tax Services Vietnam cover a wide range of tax matters for foreign employees and international companies. These services can include personal tax registration, tax residency review, PIT calculation, payroll support, annual tax finalization, tax gross-up, tax equalization, foreign income review, and tax procedures when an expatriate leaves Vietnam.

In particular, resident employment income now follows a five-bracket progressive tax schedule, while the family circumstance deductions have increased to VND 15.5 million per month for the taxpayer and VND 6.2 million per month for each dependent.

At the same time, employers must pay close attention to foreign employees who receive income from overseas organizations. Vietnam’s current rules calculate PIT on resident employment income without distinguishing where the income is paid.
