Overwhelmed by Vietnam’s PIT rules? You’re not alone. With twenty years advising on FDI in Asia, I’ve seen expats and their HR teams stumble over residency tests, dual‑income reporting, and complex withholding obligations under the PIT Law 2007 (amended 2024). Foreign individuals, including expats and freelancers, face unique tax challenges in Vietnam due to complex rules around taxable income and residency. HR leaders miss out on cost savings while expats risk costly mistakes. This is where insight turns complexity into clarity.

Income Tax in Vietnam

Income tax in Vietnam is the foundation of the country’s tax system, shaping the financial landscape for individuals and businesses. The Vietnamese government has established a comprehensive framework to ensure taxation is fair, transparent and effective for national development. At the heart of this system is personal income tax (PIT) which applies to a wide range of personal income sources – employment income, business profits and other earnings.

For tax residents, personal income tax is on worldwide income, meaning all income earned both in and outside Vietnam is subject to PIT. According to Article 2 of the PIT Law 2007 (amended 2024), a resident is defined as an individual present in Vietnam for 183 days or more within a 12-month period, or having a permanent abode. Non-residents, however, are taxed at a 20% flat rate only on their Vietnam-sourced income. This is why individuals and companies must understand their tax status and obligations. The government’s focus on compliance and anti-tax evasion means both individuals and businesses must be vigilant to avoid penalties. Navigating income tax in Vietnam requires understanding the tax system, types of income subject to PIT, and the responsibilities that come with being a tax resident or non-resident.

Key Takeaways:

• Residency Is Crucial: 183‑day physical presence (or 12‑month arrival test, or permanent residence) under Article 2, PIT Law 2007 (amended 2024) determines whether worldwide or Vietnam‑only income is taxed.
• Personal Income Tax Rates: Residents face 5–35% progressive rates on total income; non‑residents pay 20% flat on Vietnam‑source earnings (PIT Law, Schedule II).
• Taxable Benefits: Housing, school fees, relocation allowances, and stock‑based compensation all attract PIT unless specifically exempted under Circular 111/2024/TT‑BTC.
• DTAs to the Rescue: Claim relief via exemption or credit methods under your country’s DTA (over 80 in force)—submit a Certificate of Residence to GDT for credit under Law on Tax Administration 2019 (amended 2024).
• Compliance is Tough: Employers must withhold PIT monthly via the eTax portal and finalize returns by April 30 each year—late or incorrect filings incur fines up to 20% of tax due under Law on Tax Administration.
• Plan Compensation Wisely: Balance cash salary with tax‑favored benefits (e.g., relocation, education) and consider gross‑up clauses to manage PIT liabilities—structured under Circular 111/2024/TT‑BTC for maximum relief.

Tax Residency and PIT

Your first step in understanding your tax obligations is to determine your residency status. This single factor is the key to how you will be taxed in Vietnam.

As a tax resident, you are taxed on your worldwide income. Foreign-source income is taxed the same as domestic income for residents.

183-Day Rule and Residency Tests

The most common test for tax residency is physical presence. Under Clause 1, Article 2 of the PIT Law, an individual is considered a tax resident if they are present in Vietnam for 183 days or more in a calendar year or within a 12-month period from their date of arrival. Other tests also apply, such as maintaining a permanent residence or leasing a home for 90 days or more. As a tax resident, you are taxed on your worldwide income. If you do not meet these criteria, you are considered a non-resident and are taxed only on income generated in Vietnam.

Resident vs Non-Resident PIT Obligations

The difference is huge.

• Tax Residents are taxed on employment income at progressive rates from 5% to 35% (progressive rates mean higher income is taxed at higher tiers).
• Non-Residents are taxed at 20% on Vietnam-sourced income.

This is critical for structuring assignments for long-term expats and short-term project-based workers.

Taxable Income for Foreign Professionals

It’s a common myth that only your base salary is taxed. Vietnam takes a broad view of what is taxable income. Individuals carrying out business activities in Vietnam are also subject to PIT.

What is Taxable in Vietnam?

Beyond salaries and bonuses, most benefits provided by an employer are also taxable. Under Article 3, PIT Law 2007, monthly taxable income includes salary, bonuses, allowances (housing, utilities, tuition), and equity grants. Dividends and capital gains are taxed per Article 28–29 rules, depending on residency.. According to KPMG’s “Thinking beyond borders” guide (2023), this includes housing allowances, utilities and school fees for children. Equity compensation like stock options also falls within the scope of taxable income, though specific rules apply to their valuation and timing. Other income, such as dividends or capital gains, may also be subject to PIT depending on the source and residency status.

Exemptions, Allowances and Deductions

While most income is taxable, there are important exemptions and deductions. Some types of income are non-taxable, such as real estate transfers between relatives, scholarships and overseas remittances which are exempt from personal income tax and do not need to be declared. As highlighted in a 2025 guide from the Global Referral Group, certain benefits are non-taxable, such as one-time relocation allowances for moving to Vietnam, round-trip airfare for an employee’s home leave once a year and direct payments for tuition fees. Tax residents can also claim a personal deduction of VND 11 million per month and a further VND 4.4 million per month for each qualified dependent.

These exemptions are supported by Circular 111/2024/TT-BTC, which also clarifies key exemptions and deductions including:

• Scholarships, family remittances, and intra‑family real estate transfers.
• One‑time relocation allowance and annual home‑leave airfare.
• Resident Deductions: VND 11 million personal + VND 4.4 million per dependent monthly.

Foreign Contractor Withholding Tax: What Employers and Contractors Need to Know

Foreign contractor withholding tax is a key consideration for any business engaging foreign contractors in Vietnam. This tax is imposed on income earned by foreign contractors for services performed in Vietnam and it is the employer’s responsibility to withhold the appropriate amount before making payments. The applicable tax rates depend on the nature of the income and any tax treaties in place between Vietnam and the contractor’s home country which can affect the final tax rate applied.

Employers must ensure timely tax payment by withholding PIT from contractor payments and remitting it directly to the tax authorities. Missing tax payment deadlines or failing to withhold the correct amount can result in heavy penalties. Both employers and contractors must also comply with transfer pricing regulations, ensuring all transactions are at arm’s length to avoid tax authority scrutiny. Understanding foreign contractor withholding tax is key to compliance and avoiding penalties in Vietnam’s ever-changing tax environment.

Compulsory Insurances and Benefits: The Hidden Side of Payroll Compliance

Vietnam mandates contributions to social insurance (17.5% employer, 8% employee), health insurance (3% employer, 1.5% employee), and unemployment insurance (0.5% each for employer and employee) for both Vietnamese and foreign employees with work permits. These contributions are calculated on the employee’s base salary (capped at 20 times the regional minimum wage for social and health insurance) and are deductible for PIT purposes. Non-compliance with contribution deadlines (monthly, by the last day of the following month) can lead to fines and penalties.

Double Taxation Agreements and Global Income Planning

When DTAs Apply—and When They Don’t

Double Taxation Agreements are a key tool in a risk-free strategy for global mobility. These treaties prevent your income from being taxed twice, once in your home country and again in Vietnam. The relief typically works through either an exemption method (one country gives up its right to tax) or a credit method (one country allows you to deduct the tax paid in the other). You must have a Certificate of Residence from your home country’s tax authority to claim these benefits.

Structuring Compensation to Minimise Tax

Strategic insight into compensation structuring can unlock big wins. For senior executives, “gross-up” agreements, where the employer covers the PIT liability, provide certainty. But a more nuanced approach involves balancing taxable benefits with non-taxable ones and leveraging the provisions of a DTA to their full potential.

Global Minimum Tax for Multinational Employees

The global minimum tax is a major change in international tax regulation aimed at profit shifting by multinational corporations. For foreign employees in Vietnam, this means big implications especially if their employer is part of a multinational group. The global minimum tax rate is 15% and multinational companies must ensure their global tax payments meet or exceed this threshold to avoid extra tax liabilities.

Employers sending foreign employees to Vietnam need to consider the global minimum tax in their overall tax strategy and compliance obligations. Failure to comply can result in tax penalties and tax authority scrutiny. Navigating the global minimum tax requires careful planning and often tax expertise to advise on cross-border tax issues and help companies stay compliant in a rapidly changing global economy.

Filing and Compliance: What Every HR Manager Should Know

For HR and finance leaders, compliance is not just a task; it’s a risk management function. Meeting the tax payment deadline is key to avoid penalties and ensure both employers and employees are in good standing with tax authorities.

Annual Filing vs Monthly Withholding

Employers must withhold PIT from employee salaries on a monthly basis and remit it to the tax authorities. At the end of the year, a tax finalization is required. The filing window for the annual finalization is from the start of the year until the last day of the fourth month after the year-end. While the tax year for individuals is the calendar year, companies may operate on a different fiscal year which can affect reporting and compliance deadlines. In most cases, the employer can file on behalf of the employee but individuals with income from multiple sources must often file their own tax returns.

Required Documents and e-Tax Platform

Proper documentation is your best defense in an audit. This includes a valid labor contract, proof of residency, payslips and evidence for any claimed deductions. Vietnam’s tax administration operates on digital platforms and companies are required to register and use the e-Tax system for declarations and payments. Tax authorities oversee the e-Tax system and ensure compliance with tax regulations.

• Register all foreign employees for a personal tax code upon hiring.
• Determine tax residency status for each employee at the start and end of the year.
• Classify all components of compensation (salary, bonus, taxable benefits).
• Withhold and pay PIT before the deadline.
• Get required documents for dependent deductions (birth certificates, etc.).
• Prepare and submit annual tax finalization reports before the deadline.
• Provide employees with proof of tax payment for DTA claims in their home country.

Late Filing Penalties and Audit Triggers

The penalties for late filing or underpayment can be severe including interest on the outstanding tax amount and administrative fines. Common triggers for a tax audit include large cash allowances paid to employees, inconsistently reported benefits and aggressive use of split-pay contracts. Tax inspections may also be conducted by authorities to ensure compliance with tax regulations.

Advanced Tax Planning for Cross-Border and Remote Workers

Multi-Country Income and Remote Work Tax Risks

The rise of remote work has introduced new challenges. Logging into your work system from Vietnam can potentially trigger a tax presence. For employees who split their time between Vietnam and a head office, a careful day count and income apportionment are necessary to avoid tax disputes. Employers also face the risk of creating a “permanent establishment” if remote work is not managed with strategic insight. Proper documentation and reporting are essential for tax purposes when dealing with multi-country income.

Executive Tax Optimization Strategies

For senior leaders, more advanced strategies like tax equalization or tax protection policies ensure that the employee is no worse off than if they had stayed in their home country. As outlined in Deloitte’s “Vietnam Tax Highlights 2025”, the interaction of local PIT rules with international assignment policies requires careful planning to be both compliant and competitive. The choice of visa, family status and even the province of residence can all impact the final tax outcome. Executives may also benefit from preferential tax rates if they work in encouraged sectors or regions.
