1. Summary

Personal Income Tax (PIT) in Vietnam applies to all individuals’ income within the country or to enterprises employing labor. Vietnam’s tax system, which is primarily governed by the Law on Personal Income Tax (Law 109/2025/QH15) and guiding circulars, requires stringent compliance for both professionals and employers.

• Tax residency status determines tax liability. Residents, those who have been in Vietnam for 183 days or more during a calendar year or a 12-month period beginning on their first day of arrival, or those who maintain a regular place of abode in Vietnam in accordance with the law, are subject to tax on income arising both within and outside of Vietnam.
• Enterprise and expatriate compensation packages can be structured efficiently by leveraging statutory tax-exempt benefits.
• Tax withholding operates on a monthly or quarterly basis through payroll, followed by annual finalization. Corporate employers must file annual returns by March 31, while individuals directly finalizing with the tax authority have until April 30.

2. What Is Personal Income Tax (PIT)?

Definition Under Vietnamese Law

Personal Income Tax is a direct tax levied directly on the taxable income of individuals arising from employment salaries and wages, business production activities, capital investments, capital assignments, real estate transfers, copyright royalties, commercial franchising, prize winnings, inheritances, and gifts, after subtracting statutory family relief deductions, compulsory social insurance contributions, and recognized charitable donations.

In Practical Terms

Personal Income Tax is deducted from individual earnings before net cash and reaches the government bank account.

For foreign investment international businesses operating in Vietnam (FDI), managing PIT is a core strategic function rather than a simple bookkeeping task.

Foreign executives and expatriate specialists frequently negotiate employment contracts on a net-salary basis. When compensation is set to net, the corporate employer absorbs the entire tax burden.

Enterprise workforce expenses increase, and overall project margins suffer whenever organizations miscalculate gross-up tax figures or fail to capitalize on tax-free allowance opportunities.

3. Who Must Pay PIT? Determining Tax Residency in Vietnam

In Vietnam, an individual’s tax residency status, rather than their nationality, determines their tax liability. Vietnamese tax law establishes two distinct categories of taxpayers:

Classification Factor	Tax Resident	Non-Resident
Physical Presence in Vietnam	Present in Vietnam for 183 days or more in a calendar year, or across 12 consecutive months from the initial date of arrival.	Present in Vietnam for fewer than 183 days in the relevant tax year.
Permanent Residence / Lease	Holds a registered permanent or temporary residence (TRC) or leases residential accommodation in Vietnam for 183 days or more.	Does not maintain a permanent residence or holds residential leases totaling fewer than 183 days.
Taxable Income Scope	Worldwide Income: Taxed on all income generated both inside and outside Vietnam, regardless of payment location.	Vietnam-Sourced Income Only: Taxed solely on income generated from work performed within Vietnam territory.
Applicable Salary Tax Rate	5-bracket progressive rate from 5% to 35%; eligible for personal and dependent family deductions.	Flat 20% tax rate on employment income; no family deductions allowed.
Burden of Proof	If renting a home for 183 days or more but staying under 183 days, must present a foreign Tax Residence Certificate to avoid resident status.	Must present passport arrival/departure stamps and home country fiscal residency proof.

The 183-Day Rule and the Rental Lease Presumption

Many expatriates mistakenly assume that spending fewer than 183 days physically in Vietnam automatically grants them non-resident status.

Under Circular 111/2013/TT-BTC, the tax authority presumes an individual to be a Vietnam Tax Resident if they sign a residential lease agreement for a house, apartment, or hotel room. This presumption applies if the lease term is 183 days or longer within a tax year.

To override this situation, the individual must provide a valid Certificate of Tax Residence issued by their home country tax authority for the same tax year. If they cannot document tax residency in another sovereign state. They are classified as a Vietnam Tax Resident and taxed on their worldwide earnings.

4. Taxable Income Categories: Worldwide Income, Overseas Payroll, and Digital Nomads

Vietnamese tax legislation identifies ten distinct categories of assessable income. For international personnel and enterprises, the following streams require careful management:

1. Employment Income: Salaries, wages, overtime pay, allowances, operational subsidies, performance bonuses, directors’ fees, and monetary or non-monetary benefits provided by employers.

2. Capital Investment Income: Dividends from joint-stock companies, profit distributions from limited liability companies, and interest received from corporate loans (personal bank deposit interest remains tax-exempt).

3. Capital Transfer Income: Gains realized from transferring capital contributions in LLCs (taxed on net profit) or selling shares and securities in joint-stock corporations (taxed on total gross sales proceeds).

4. Real Estate Transactions: Revenues earned from transferring real estate ownership, land use rights, or leasing physical property.

5. Royalties, Franchising, and Capital Gifts: Royalties from intellectual property, commercial franchising fees, lottery winnings, inheritances, and gifts with an individual value exceeding 10 million VND.

Special Case 1-Expatriates Paid Abroad

A frequent compliance vulnerability arises when foreign employees perform work in Vietnam but receive part or all of their remuneration directly from an overseas parent company into a foreign bank account (split payroll).

Under Vietnamese law, if the work is executed in Vietnam, that income is legally Vietnam-sourced.

For tax residents, worldwide income is taxable regardless of where funds are disbursed. Employers and employees are legally obligated to declare all offshore salary portions, converting foreign currencies into VND.

Omitting offshore compensation during tax filings constitutes tax under-declaration and evasion, exposing the business to heavy retrospective tax assessments and criminal liability.

Special Case 2-Remote Workers & Freelancers

Foreigners living in Vietnam on investor, business, or temporary visitor visas while providing remote consulting, software engineering, or creative services to foreign clients fall under strict tax scrutiny.

If they remain in Vietnam for 183 days or more in a calendar year, they become Vietnam Tax Residents.

They must register for a Vietnamese personal tax code and declare their worldwide service revenues.

Service income from independent commercial activities is subject to business tax rates or standard progressive employment tax rates.

5. Applicable PIT Rates: Progressive Brackets and Flat Tax Rates

Vietnam applies two taxation mechanisms: a progressive tax schedule for resident employment income. Flat proportional tax rates for non-residents and non-employment income streams.

Progressive Tax Brackets for Resident Employment Income

Monthly taxable income from employment is calculated by taking gross earnings and subtracting statutory insurance contributions, family relief allowances, and eligible non-taxable fringe benefits. The net figure is applied against the 5-bracket progressive schedule:

Flat Tax Rates on Other Income Categories

For non-resident employment income, the flat rate is 20%, and for non-wage income streams, flat tax rates apply without deductions:

Income Category	Tax Rate	Tax Calculation Base
Capital Investment (Dividends/Interest)	5%	Gross dividend or loan interest received
Capital Transfer (LLC Equity)	20% on net gain; or2% on sale proceeds	Net gain / Gross sales price
Securities / Shares in JSC	0.1%	Gross transfer proceeds per transaction
Real Estate Transfers	2%	Gross contract sales proceeds
Royalties & Franchising	5%	Income portion exceeding 20,000,000 VND per contract
Prizes, Inheritances, Gifts	10%	Asset value portion exceeding 20,000,000 VND per occurrence
Business / Independent Services	1% to 5%	Gross commercial service revenue by industry

6. Tax Period, Withholding Mechanisms, and Annual Finalization Deadlines

Vietnam’s personal tax administration operates on a continuous withholding and annual reconciliation cycle.

The Tax Year Framework

For tax residents, the standard tax period matches the solar calendar year (January 1 to December 31).

For foreign employees arriving in Vietnam for the first time, if their physical presence in the first calendar year is fewer than 183 days, their first tax year is calculated as 12 consecutive months starting from their first arrival date.

In the subsequent year, their tax period aligns back to the standard calendar year.

Monthly Withholding and the 10% Service Contract Rule

Employers must calculate and withhold provisional PIT each time salary is disbursed.

For local or foreign personnel engaged under temporary service or consulting contracts without formal labor contracts of 3 months or longer, the paying organization must withhold a flat 10% tax on any payment of 5 million VND or higher.

If the individual estimates their total annual income will fall below the taxable threshold, they may execute a formal commitment form (Form 08/CK-TNCN) to temporarily waive the 10% withholding.

Annual PIT Finalization

At year-end, provisional withholdings are balanced against actual full-year tax liability.

An employee may authorize their employer to finalize taxes on their behalf. Only if they have a single source of employment income during the year and are currently employed at the company.

Individuals who worked for two or more employers, individuals claiming personal tax refunds, or expatriates concluding their Vietnam contracts prior to departure must complete direct self-finalization with the local tax department.

Deadline for authorization and self-declaration

Corporate Filing Deadline (March 31): Enterprises paying employment income must consolidate all staff earnings, prepare Form 05/QTT-TNCN, and submit the filing to the tax authority no later than the last day of the third month following fiscal year-end (March 31).

Individual Direct Filing Deadline (April 30): Individuals who must file directly with the tax department have until the last day of the fourth month following year-end (April 30; if falling on a public holiday, extended to the next business day).

7. Tax-Exempt Income and Strategic Expatriate Fringe Benefits

Structuring compensation packages to maximize non-taxable allowances is fully legitimate under Vietnamese tax law and significantly reduces overall payroll costs.

1. Statutory Family Relief and Deductions:

• Personal Relief: 15,500,000 VND per month (186,000,000 VND per year) automatically deducted from gross income before applying tax brackets.
• Dependent Relief: 6,200,000 VND per month per qualifying dependent (minor children under 18, adult children in university with no income, or elderly parents unable to work). Dependent tax codes and supporting birth/family certificates must be registered with the tax bureau.
• Compulsory Insurance Deductions: Mandatory employee contributions for Social Insurance (8%), Health Insurance (1.5%), and Unemployment Insurance (1%) are 100% tax-deductible, along with voluntary pension contributions up to 1 million VND per month.

2. Non-Taxable Expatriate Allowances and Benefits:

Under Circular 111/2013/TT-BTC and related decrees, foreign employees can receive specific tax-exempt benefits when properly documented in employment contracts and company policies:

• Annual Home Leave Airfare: One round-trip airfare per year paid by the employer for the foreign employee to visit their home country is 100% exempt from personal income tax.
• Children’s School Tuition Fees: Tuition fees for general education (from kindergarten/preschool through high school grade 12) in Vietnam for children of expatriate employees, paid directly by the employer to the educational institution, are completely tax-exempt.
• The 15% Housing Benefit Ceiling: When an employer provides or rents housing for an employee, the taxable housing benefit included in employment income is legally capped at 15% of the employee’s total other taxable income (excluding housing). Any actual rental payment exceeding this 15% ceiling is completely tax-free.
• Lunch Allowances: Mid-shift lunch allowances are tax-exempt up to 1,200,000 VND per month if paid in cash, or entirely tax-exempt if the employer provides canteen meals or lunch catering directly.
• Uniform Allowances: Uniform allowances are tax-free up to 5,000,000 VND per employee per year if paid in cash, and fully tax-free without monetary limits if uniforms are provided in-kind with official VAT invoices.
• Relocation Allowances: One-time relocation allowances provided to foreign experts moving to Vietnam are non-taxable when supported by relocation invoices and flight tickets.

8. Double Taxation Avoidance (DTA) Agreements: How Foreign Personnel Prevent Dual Taxation

Vietnam has signed and enforced bilateral Double Taxation Avoidance (DTA) agreements with more than 80 countries and territories.

Including Singapore, Japan, South Korea, the United States, the United Kingdom, Germany, France, and Australia.

Core Objectives of Tax Treaties

DTAs prevent international personnel and multinational corporations from paying income tax twice on the same commercial earnings.

Vietnamese taxes can offset home country tax liabilities, or specific employment income may be fully exempt from Vietnamese tax. If qualifying criteria are met.

Three Mandatory Conditions for Employment Income Exemption Under DTA

A foreign employee assigned to work in Vietnam by an overseas enterprise is exempt from Vietnamese personal income tax on employment earnings if they simultaneously satisfy three conditions:

• The employee is physically present in Vietnam for fewer than 183 days in the relevant calendar year or 12-month period.
• The employer paying the compensation is not a tax resident of Vietnam.
• The salary expense is not borne or reimbursed by a permanent establishment (PE) or branch of the foreign enterprise located in Vietnam.

Procedural Requirements and Submission Deadlines

DTA tax exemption is not granted automatically.

The taxpayer or their employer must prepare a formal DTA exemption dossier. This dossier includes:

• The official DTA notification form
• An original Certificate of Tax Residence issued by the home country tax authority (consularly legalized and translated into Vietnamese)
• Certified employment contracts
• The original passport

The dossier must be submitted to the local Vietnamese tax department at least 15 days prior to commencing work in Vietnam or alongside the annual tax finalization return.

If the dossier is not submitted on time, treaty benefits will be forfeited, leading to standard 20% non-resident tax assessments and daily late payment interest of 0.03%.
