If you work in Vietnam as a foreign national, personal income tax (PIT) can depend on more than your nationality, visa, employer or number of days in the country. The starting point is whether Vietnam treats you as a tax resident, where the work is performed and which tax year is being assessed.
This guide explains Vietnam tax for foreign workers, including the residency tests, 2026 PIT rates, deductions, salary paid from overseas, employer withholding, annual tax finalization and double-tax treaty questions. It focuses on income from employment rather than business profits, investments or property transactions.
Quick answer
Foreign workers may owe Vietnam PIT on employment income. Tax residents generally fall under progressive rates and a worldwide-income scope; non-residents are generally taxed at 20% on employment income arising in Vietnam. Residency and treaty relief must be established from the facts, not assumed from a work permit or a short visit.
1. Do foreign workers pay income tax in Vietnam?
Often, yes. Vietnam taxes qualifying employment income under its personal income tax rules. Foreign nationality does not itself create an exemption, and having a valid work permit does not automatically make someone a tax resident. Equally, staying for fewer than 183 days does not automatically eliminate Vietnam tax.
The practical questions are whether you are a resident or non-resident for tax purposes, whether the income is taxable under Vietnam's domestic rules, and whether an applicable tax treaty changes the result. An employee may also need to consider overseas payroll, local employer cost allocations and tax withheld in another country.
| Question | Why it matters |
|---|---|
| Am I a Vietnam tax resident? | Determines the general income scope and the relevant resident salary tax schedule. |
| Where were my work duties performed? | Can affect the Vietnam-source element, including when a foreign company pays the salary. |
| Which tax year is involved? | The 2026 salary brackets differ from the rules for a 2025 tax-year return. |
| Is there an applicable treaty? | A treaty may change a result if all relevant eligibility and employment conditions are met. |
Legal basis: Vietnam's consolidated PIT Law 112/VBHN-VPQH and the October 2026 government tax-office explanation.
2. Vietnam tax residency: the 183-day rule and the accommodation test
The most familiar test is physical presence. Under Decree 253/2026/ND-CP, an individual may qualify as a resident if present in Vietnam for 183 days or more during a calendar year or during 12 consecutive months starting from the first arrival. Arrival and departure days count; entering and leaving on the same day counts as one day.
However, physical presence is not the only route to residency. A qualifying permanent or registered place of residence, including certain temporary-residence-card application records, can matter. A qualifying housing arrangement involving rental periods totaling 183 days or more during the tax year can also matter, including arrangements made by an employer. If a person has a qualifying place of residence but spends fewer than 183 days physically in Vietnam, evidence of tax residence in another country may affect the classification.
Physical-presence test
Track actual arrival and departure dates and assess the applicable calendar-year or first-12-month period. A travel log should be supported by entry and exit records.
Accommodation and foreign residence
Check the type of registered address, housing contracts, rental duration and any valid evidence of residence in another jurisdiction.
Example: A person who stayed 120 days in Vietnam may not satisfy the physical-presence test. It would still be unsafe to label that person non-resident without checking their qualifying housing or registration arrangements and any evidence of tax residence elsewhere.

3. Tax residents vs non-residents: what income is taxable?
The distinction affects both the tax base and the calculation method. Vietnam tax residents are generally assessed on taxable income arising inside and outside Vietnam, regardless of where the salary is paid or received. Non-residents are generally assessed on taxable income arising in Vietnam, also regardless of where payment is made or received.
| Issue | Tax resident | Non-resident |
|---|---|---|
| Employment-income scope | Generally taxable worldwide employment income | Generally employment income arising in Vietnam |
| Common domestic salary rate | Five progressive marginal bands for the 2026 tax year | Generally 20% on qualifying Vietnam-source employment income |
| Personal and dependent relief | Potentially available if statutory conditions are met | Do not assume resident salary deductions apply |
| Treaty considerations | An applicable treaty may modify the domestic result; the country and facts must be reviewed. | |
Do not interpret the 20% rule as meaning that every foreign employee pays a flat 20%. Resident employees are generally covered by the progressive resident scale; non-resident treatment depends on a valid residency analysis and the source of the income.
4. Vietnam personal income tax rates for foreign workers in 2026
For resident individuals' employment income in the 2026 tax year, Vietnam's updated law provides a five-band progressive schedule. The law generally took effect on 1 July 2026, while provisions relating to the wages and salaries of resident individuals apply from the 2026 tax year. A 2025 tax-year return submitted during 2026 should not be confused with 2026 income.
| Band | Monthly taxable income | Annual taxable income | Marginal rate |
|---|---|---|---|
| 1 | Up to VND 10 million | Up to VND 120 million | 5% |
| 2 | Over VND 10m to 30m | Over VND 120m to 360m | 10% |
| 3 | Over VND 30m to 60m | Over VND 360m to 720m | 20% |
| 4 | Over VND 60m to 100m | Over VND 720m to 1.2bn | 30% |
| 5 | Over VND 100 million | Over VND 1.2 billion | 35% |
These percentages are marginal rates. Reaching the 20% bracket does not mean that all your taxable income is taxed at 20%. The 35% rate applies only to the portion above the top threshold, not to the entire salary.

5. How to estimate monthly personal income tax
First distinguish gross salary, taxable employment income and income subject to the progressive calculation after permitted deductions. They are not interchangeable. Relevant mandatory insurance contributions, personal and dependent relief, and other permitted deductions may need to be taken into account before applying the rate table.
Illustration: VND 45 million of monthly taxable income
Assume an individual is a Vietnam tax resident and has VND 45 million remaining after all applicable deductions. This is an arithmetic example, not a gross-salary calculation.
| Taxable slice | Calculation | Tax |
|---|---|---|
| First VND 10m | 10m × 5% | VND 0.5m |
| Next VND 20m | 20m × 10% | VND 2m |
| Remaining VND 15m | 15m × 20% | VND 3m |
| Illustrative monthly PIT | VND 5.5m |
Actual payroll withholding and final annual liability can differ because the example assumes the tax base has already been established and ignores special adjustments, foreign-tax relief and filing circumstances.
If your offer letter states a gross or net salary, ask your payroll team which components are treated as taxable, which contributions are deducted and what assumptions have been used. A net-pay commitment may be calculated differently from a standard gross-pay arrangement.
6. Deductions and relief available to qualifying tax residents
The 2026 law sets a personal family-circumstances reduction of VND 15.5 million per month for an eligible resident taxpayer and VND 6.2 million per month per eligible dependent. These deductions affect taxable income, not the tax bill VND-for-VND.
| Potential deduction | 2026 treatment and important condition |
|---|---|
| Personal relief | VND 15.5 million/month for an eligible resident individual. |
| Qualifying dependent | VND 6.2 million/month per eligible dependent, subject to registration and evidence rules; one dependent cannot be claimed by multiple taxpayers for the same relief. |
| Relevant insurance contributions | Specified mandatory contributions and other contributions permitted by law may be deductible subject to conditions and limits. |
| Certain domestic healthcare costs | Up to VND 23 million/year for eligible expenses meeting the medical-service, invoice, reimbursement and documentation tests. |
| Certain domestic education and training costs | Up to VND 24 million/year for eligible domestic education/training expenses with the required documentation and without prohibited reimbursement. |
Who counts as a dependent?
Children and other relatives are not automatically eligible merely because you support them. The law defines specific dependent categories, ages or capacity conditions, and evidence requirements. For certain categories, Circular 87/2026/TT-BTC refers to an average monthly income from all sources of no more than VND 3 million. Do not apply that threshold indiscriminately to every child or relative.
Healthcare and education are not blanket expat allowances
Only specified costs incurred at eligible facilities in Vietnam can qualify. You may need compliant invoices, patient or student details and supporting medical paperwork. Amounts paid by insurance, an employer or another party are not automatically deductible again. These rules are not a general deduction for overseas school fees or any private health insurance premium.

7. Salary paid from abroad: can you still owe Vietnam tax?
Yes, depending on the facts. Receiving salary into an overseas bank account does not automatically remove Vietnam PIT. Equally, a foreign salary transferred into a Vietnam bank account does not automatically become taxable in Vietnam simply because of the transfer.
A Vietnam tax resident generally falls within the taxable worldwide employment-income scope, regardless of where payment is made. For a non-resident, the Vietnam-source analysis is central. This can become complicated when an employee works remotely for a foreign company, is seconded to a Vietnamese company, or has compensation paid abroad but ultimately charged to an entity in Vietnam.
Foreign company, work in Vietnam
Review physical work location, tax residence, the actual employer and any treaty provisions. Foreign payroll alone is not an exemption.
Vietnam company, overseas assignment
Review residence status, where the duties occur, any overseas taxes and whether relief is available under the relevant rules.
Foreign salary wired to Vietnam
The bank-transfer destination is not the deciding legal test. Check the origin of the salary and the recipient's tax status.
In an October 2026 government-published tax-office answer about Japanese employment income paid into a Vietnam bank account, the authority explained the need to establish tax residence and the income's territorial scope. That example is useful for understanding the approach, but it is not a ruling for every cross-border employee.
Keep employment agreements, payroll summaries, workday records and evidence of any tax paid overseas. Where income allocation or foreign-tax relief is contested, obtain case-specific advice from a qualified tax professional.

8. Employer withholding: what may be deducted from your pay?
Tax withholding is a payment mechanism, not always the final measure of a person's annual liability. In typical resident employment, the payer uses the applicable taxable monthly income and progressive schedule when withholding, subject to the relevant rules and exceptions.
Under Article 50 of Decree 253/2026/ND-CP, a payer making certain employment or remuneration payments to a resident individual without a contract or with an employment contract shorter than three months must generally withhold 10% when an individual payment is VND 5 million or more. Specific exceptions or declarations may affect temporary non-withholding. For payments below that threshold, the rule also allows withholding at the individual's request.
That short-contract rule should not be treated as the tax rate for every foreign freelancer, every non-resident or every long-term employee. Classification of the contract, employment relationship, tax residence and source of income still matters.
9. Double taxation agreements: why 183 days is not an automatic exemption
A double taxation agreement (DTA), where applicable, can allocate taxing rights or provide relief from double taxation. However, the treaty employment exemption is not the same as Vietnam's domestic tax residency test, even where both refer to 183 days.
Vietnam's 2026 treaty guidance describes an employment-income exception requiring multiple conditions to be satisfied together. The familiar issues include the individual's presence in Vietnam during the treaty-defined period, whether the actual employer is resident in Vietnam, and whether the remuneration is borne by a Vietnam permanent establishment of that employer. The precise treaty and its protocols control the applicable test.
| Domestic tax residence | Potential treaty employment exemption |
|---|---|
| Determines whether domestic resident or non-resident rules apply. | May restrict Vietnam's taxing right over specific employment income. |
| Looks at physical presence and qualifying accommodation, among other facts. | Requires the relevant treaty's time test and other employer/expense conditions. |
| Cannot be decided solely by a visa label. | Cannot be decided solely by a stay of fewer than 183 days. |
| May involve evidence of foreign tax residence. | Typically requires treaty eligibility and adequate tax-residence/employment evidence. |
A worker may also ask whether foreign income taxes can be credited against Vietnam PIT. Any such relief requires the applicable rules, acceptable proof and relevant limitations. It is not a promise that all overseas tax paid will be refunded or deducted in full.
Reference for general treaty principles: Circular 95/2026/TT-BTC, Article 34 (third-party legal text). For any claim of entitlement, check the authoritative circular and the actual treaty with a qualified adviser.
10. Tax registration, annual finalization and filing deadlines
Employers often handle routine payroll withholding. That does not mean they can always finalize an individual's PIT or that the employee has no independent obligations. Your filing route depends on your income sources, employment arrangements, possible deductions, refund request and departure situation.
When can an employer finalize for you?
Article 51 of Decree 253 permits employer-authorized finalization in certain cases, including eligible employees with an employment contract of at least three months and the relevant single-employer or specifically permitted additional-income circumstances. Other income, requests for certain deductions or particular departure situations can change the answer.
Annual deadlines to know
| Filing situation | General deadline principle |
|---|---|
| Tax-paying employer or income payer's annual finalization | Generally by the last day of the third month after the finalization period. |
| Individual directly finalizing annual employment PIT | Generally by the last day of the fourth month after the calendar year. |
| First-year 12-month residency determination | A separate first-period timing rule may apply, based on the relevant 12-month end. |
| Qualifying resident foreign employee ending a Vietnam employment contract | Finalization before departure and no later than 45 days after contract termination, subject to the applicable facts. |
These are general rules, not a universal filing calendar for every taxpayer. Public holidays, formal extensions, prior-year returns, filing status and year-specific implementing guidance can affect a real deadline. The special departure rule is linked to contract termination, not simply 45 days after the flight out of Vietnam.
Do you need to file personally?
Some taxpayers may be exempt from finalization or allowed to authorize an employer, while others must file directly. For example, rules allow limited exceptions where tax due is below tax already paid and no refund or credit is sought, or where specifically defined additional income has already been withheld. These are narrow exceptions, not a statement that the underlying income is tax-free.
Before filing, confirm whether you have a tax identification number, what your employer has reported, whether you need withholding evidence, and whether a refund, offset or additional payment is involved. For current forms, channels and required attachments, follow the official tax authority's instructions for your situation rather than an undated screenshot of an eTax interface.

11. Foreign worker tax checklist: what to prepare before filing
Keep a personal record of the facts needed to establish your tax position. A good checklist reduces the risk of missed deductions, incorrect residency assumptions and confusion over overseas payroll. You should retain these records securely for your own employer, tax authority or independently chosen qualified adviser.

12. Frequently asked questions about Vietnam tax for foreign workers
Do all foreigners pay 20% personal income tax in Vietnam?
No. The general 20% domestic salary rate concerns qualifying non-resident Vietnam-source employment income. Resident employees generally use the progressive five-band schedule for the 2026 tax year.
If I stay less than 183 days, am I automatically a non-resident?
No. Qualifying accommodation or registered-residence facts and proof of residence elsewhere may also be relevant. The day count alone does not always settle the classification.
Does a work permit or TRC automatically make me a tax resident?
Neither document alone resolves the tax analysis. Some registered-residence information associated with immigration documentation may be relevant, but the applicable statutory tests still need to be applied.
Will I owe PIT if my salary goes into a foreign bank account?
Payment location alone is not decisive. Your residence classification, the source of employment income and any treaty treatment need to be assessed.
Is a salary received into a Vietnam bank account automatically taxed in Vietnam?
No. A bank transfer is not, by itself, the complete legal test for employment-income tax. The underlying income and residence facts matter.
Do foreign teachers follow a special flat salary tax rate?
Teaching English or working in education does not by itself create a universal special PIT rate. The employee's tax residency, income source, contract and other applicable rules still determine the treatment.
Can I claim VND 6.2 million per month for every family member?
No. Each person must qualify under the legal dependent categories, documentation and registration conditions. Some dependent categories also have income and capacity tests.
Does a double-tax treaty exempt every worker under 183 days?
No. Treaty relief depends on the actual treaty and further conditions, including employer and remuneration-cost factors. A 183-day count is not a stand-alone exemption certificate.
Can my employer always submit the annual PIT finalization for me?
No. Employer authorization is limited to eligible cases. Multiple income sources, certain deductions, refunds or termination/departure facts can require a different filing route.
Do I use the 2026 tax brackets for my 2025 salary?
No. A return for the 2025 tax year should use the rules applicable to 2025, even if the return is submitted in 2026. The five-band table in this guide is for relevant 2026 income.
