Under Vietnamese personal income tax, the starting point for an expatriate package is simple: everything the employee receives because of employment is taxable employment income — cash, allowances and benefits paid in kind — unless the law specifically exempts it or excludes it. Several items typical of expatriate packages have long had special treatment: housing is taxable but only up to a cap, and school fees for expatriates' children and an annual home-leave trip have been excluded under conditions. Whether and how those rules continue depends on the current PIT law and its guidance, so each item needs checking against the text in force.
The second point is the one that causes most back-tax: when the company agrees to pay the employee's tax — a net-pay or tax-equalised package — the tax paid is itself a benefit, and taxable income must be grossed up. This guide covers both, item by item, for HR and payroll teams that design or run expatriate packages.
Where the rules sit
Taxable employment income, exemptions and exclusions are set by the Law on Personal Income Tax, now guided by Decree 253/2026/ND-CP and Circular 87/2026/TT-BTC; for earlier years, Circular 111/2013/TT-BTC was the reference most advisers used. The rules on expatriate items were developed mostly in that older guidance. We describe the long-standing treatment below and flag where you should confirm it; we do not restate 2026 provisions.
Deductibility of the same costs for the company is a separate question under corporate income tax. As a rule, expatriate benefits are deductible for CIT when they are set out in the labour contract, assignment letter or internal policy and supported by documents — which is another reason to write the package down properly.
Item by item: the usual treatment
| Item | Long-standing treatment | What to check |
|---|---|---|
| Housing paid by the employer | Taxable, but only up to a cap linked to the employee's other taxable income | The cap and how it is calculated |
| School fees for children of expatriates, kindergarten to high school in Vietnam | Excluded from taxable income when paid by the employer under the conditions set | Whether the exclusion and its conditions continue |
| Annual home-leave trip | One round trip a year excluded when paid by the employer | Frequency, who travels, documentation |
| One-off relocation allowance on arrival | Excluded under conditions | Whether it is truly one-off |
| Cost-of-living, hardship, language allowances | Taxable | — |
| Company car used privately, club memberships | Generally taxable when they benefit the individual | How private use is identified |
Treat the table as a map of where to look, not a ruling. The conditions attached to each exclusion — for example, payment made directly by the employer to the school or airline, or the benefit written into the contract — have often decided the outcome in audits.
Housing: the cap and the paperwork
Employer-provided housing is the largest benefit in most packages. Under the long-standing rules it is included in taxable income but only up to a cap calculated by reference to the employee's other taxable income; the part above the cap is not taxed. Check the current cap before setting up the calculation, and remember that utilities, furniture rental and service charges may be treated differently from the rent itself.
Paperwork decides whether the treatment holds. A lease in the company's name, rent paid directly by the company to the landlord against a proper invoice, and a clause in the assignment letter describing the benefit make the position clear. Cash housing allowances paid through payroll, with no lease on file, are much harder to defend as housing and may simply be treated as salary.
Housing also interacts with residence: a rented home in Vietnam is part of the habitual residence test, so the housing arrangement can affect whether the expatriate is a tax resident at all.
Net-pay packages and gross-up
Many expatriates are hired on a net basis: the employee receives an agreed amount after tax and the company pays whatever tax arises. The Vietnamese rules treat the tax paid by the company as additional income of the employee. Taxable income therefore has to be grossed up — worked back from the net amount to the gross amount that, after tax at the progressive rates, leaves the agreed net.
Practical points:
- Run the gross-up every month in payroll, not once a year; bonuses and benefits in kind change it.
- Gross up benefits in kind as well as cash, if the company also bears the tax on them.
- Keep the net agreement in writing. Without it, the tax office may treat the payroll figures as gross and question the tax the company has paid.
- Make sure the rates loaded for the gross-up are the current ones; a gross-up calculated on old bands compounds the error.
Tax equalisation policies, where the employee bears a notional home-country tax and the company covers the actual host-country tax, work the same way in Vietnam: the company-paid Vietnamese tax is income and must be grossed up.
Insurance, pensions and social security
Foreign employees who hold work permits generally participate in compulsory social insurance in Vietnam under the social insurance law, with exceptions such as certain intra-company transferees; health insurance applies as well. The employee's compulsory contributions are deducted from taxable income. Check the current participation rules for each assignee type.
Voluntary cover is different. Premiums the company pays for life or other insurance that benefits the individual can be taxable employment income, depending on the type of product and the rules on voluntary pension and insurance schemes. Group policies bought at regional level for all staff should be reviewed for the Vietnamese employees before the first premium is allocated to them.
Contributions to a home-country pension or social security scheme are a treaty and social-security-agreement question as well as a PIT one; they need a specific analysis rather than a default.
Share awards and bonuses from the parent
Options, restricted share units and performance shares granted by a foreign parent to employees of a Vietnamese subsidiary are generally income from employment in Vietnam for the period the employee worked here, even though the parent grants them and the shares are held abroad. When the income arises and what value is used are set by the rules, and group plan documents written for another country rarely map neatly onto them. Take advice on each plan, and set up a process so that vesting and exercise events reach the Vietnamese payroll.
Bonuses paid by the parent follow the same principle: work performed in Vietnam gives Vietnam-source income, wherever the bonus is paid. If the Vietnamese company does not pay it, the employee usually has to declare it directly — which many do not realise until finalisation.
Designing a package that holds up
- Write every benefit into the labour contract or assignment letter, with who pays and how.
- Pay housing, school fees and travel directly to the provider where the rules make that a condition.
- Decide net or gross at the start, and document it.
- Route parent-paid items, including share awards, into Vietnamese payroll or into the employee's own declaration.
- Review the package against the current PIT and CIT rules each year, and after any change in the law.
The individual can check the tax withheld for them in the individual e-tax account or the mobile tax app; the company sees its withholding returns in its e-tax account. Where the two views differ at year end, the cause is usually a benefit that never reached payroll.
Frequently asked questions
Is employer-paid rent taxable for an expatriate in Vietnam?
Yes, but under the long-standing rules only up to a cap linked to the employee's other taxable income. Check the current cap and keep the lease and payment records.
Are international school fees for my children taxable?
Fees paid by the employer for expatriates' children at kindergarten to high school level in Vietnam have long been excluded under conditions. Confirm the exclusion and its conditions under the current rules, and have the employer pay the school directly.
My contract guarantees my net salary. Who pays the tax?
The company pays it, but the tax it pays counts as your income, so taxable income is grossed up. Keep the net agreement in writing so the calculation can be explained.
Is the tax on share awards from our overseas parent due in Vietnam?
Generally yes, to the extent the award relates to work performed in Vietnam. The timing and value are set by the rules, so take advice on each plan and make sure vesting events reach payroll.
Do foreign employees pay social insurance in Vietnam?
Foreign employees with work permits generally participate in compulsory social insurance, with exceptions such as certain intra-company transferees. Their compulsory contributions reduce taxable income.
Is a cash housing allowance treated the same as company-paid rent?
Not necessarily. Without a lease and direct payment, a cash allowance is harder to defend as housing and may be treated as ordinary salary. Structure the benefit before the first payment.
Are home-leave flights for my whole family excluded from tax?
The long-standing exclusion covered one round trip a year paid by the employer, and its conditions define who can travel under it. Check the current rules and have the employer buy the tickets or pay the airline directly.
