How Is PIT Calculated on Housing Allowance for Foreign Workers in Vietnam?
Vietnam taxes employer-paid housing as employment income, but with a statutory ceiling: only the portion not exceeding 15% of the employee’s other taxable income enters the personal income tax base. Whether you hit that ceiling depends on two variables: your tax residency status, which determines whether progressive rates of 5%–35% or a flat 20% applies, and whether your contract is structured as Gross or Net. This guide covers the rules, the calculation steps, and the worked examples you actually need.

What Qualifies as a Taxable Housing Benefit Under Vietnam’s PIT Rules?
A housing benefit is subject to Vietnam’s personal income tax when the employer pays rent directly to a landlord on behalf of the foreign employee. Vietnamese tax law calls this arrangement “trả thay” (paid in lieu). Under this structure, the amount added to the PIT base is capped at 15% of the employee’s total other taxable income in the same pay period. Rent above that ceiling is excluded from the PIT calculation entirely.
Article 11 of Circular 111/2013/TT-BTC, as supplemented by Circular 92/2015/TT-BTC, establishes this rule: housing paid by the employer on behalf of the employee is counted as taxable income at the actual amount paid, but not exceeding 15% of total taxable income from wages and salary arising at that employer in the same period, excluding the housing costs themselves. The rule applies regardless of whether the income is paid from inside or outside Vietnam.
The nature of the housing arrangement determines which tax treatment applies:
| Housing Arrangement | Subject to PIT? | 15% Cap Applies? |
|---|---|---|
| Employer pays rent directly to landlord (trả thay) | Yes | Yes |
| Cash housing allowance folded into monthly salary | Yes, full amount | No |
| Employer-provided housing at industrial zones (free of charge) | No | N/A |
| Employer-built housing at economically difficult areas | No | N/A |
The critical operational distinction is between housing paid by the company directly to the landlord and a cash housing allowance added to the monthly payslip. Only the “trả thay” structure benefits from the 15% ceiling.
When a fixed housing allowance is included in the payslip as a standard salary component, without separate documentation as a direct rent payment, Vietnam’s tax authorities treat the full amount as regular employment income. The 15% cap does not apply, and the entire allowance is taxable. For foreign teachers and professionals, the employer should confirm in writing which structure applies and document it consistently in the labor contract or salary policy to avoid PIT underreporting risk during audit.
How Much of the Housing Allowance Is Actually Subject to PIT?
The taxable housing amount is the lower of two figures: the actual rent the employer pays, or 15% of the employee’s total other taxable income from the same employer in that pay period. Rent above the ceiling is simply excluded from the PIT base. If actual rent falls below the ceiling, the full rent amount is taxable.
Article 11 of Circular 111/2013/TT-BTC specifies that the 15% base is calculated on total taxable income from wages and salary arising at that employer, explicitly excluding the housing amount itself, as well as tax-exempt income items such as annual round-trip airfare, children’s school fees paid directly to an educational institution, and meal allowances within the legally specified limit.
| Scenario | Actual Rent (VND) | 15% Cap (example: VND 50M base) | Taxable Housing Added (VND) |
|---|---|---|---|
| Rent below cap | 5,000,000 | 7,500,000 | 5,000,000 (actual) |
| Rent equals cap | 7,500,000 | 7,500,000 | 7,500,000 |
| Rent above cap | 15,000,000 | 7,500,000 | 7,500,000 (capped) |
| Rent far above cap | 30,000,000 | 7,500,000 | 7,500,000 (capped) |
The “total other taxable income” base includes base salary, performance bonuses, taxable allowances, and all other taxable employment benefits from that employer in the same period. A one-time bonus in a given month increases the base for that month, raising the 15% ceiling accordingly. For a foreign teacher earning VND 30,000,000 in base salary plus a VND 5,000,000 taxable bonus in December (total VND 35,000,000), the housing ceiling for December is VND 5,250,000, not VND 4,500,000.
A higher base income produces a higher ceiling. An employee on a lower salary may find that most or all of their employer-paid rent falls within the cap and is therefore fully taxable.

How Does Tax Residency Status Determine the PIT Calculation Method?
Tax residency status determines which rate structure applies: the 5-bracket progressive system (5%–35%) for tax residents, or a flat 20% for non-residents. A foreign worker qualifies as a tax resident if they are present in Vietnam for 183 days or more in a calendar year or 12 consecutive months from first entry, hold a rental contract of 183 days or more in the tax year, or have a registered permanent or temporary address in Vietnam confirmed by immigration authorities.
Personal Income Tax Law No. 109/2025/QH15, effective from 01 January 2026, defines tax residency through these same criteria. The law also restructured the progressive brackets from 7 to 5 and increased personal deductions, both of which directly affect the net PIT liability on housing income for tax residents.
| Criteria | Tax Resident | Non-Resident |
|---|---|---|
| Presence threshold | 183 days or more in Vietnam | Under 183 days |
| PIT rate structure | Progressive 5 brackets (5%–35%) | Flat 20% |
| Self-deduction (from 01 Jan 2026) | VND 15,500,000 per month | None |
| Dependent deduction (from 01 Jan 2026) | VND 6,200,000 per person per month | None |
| Social insurance deduction | Eligible if enrolled | Not eligible |
| Tax base scope | Worldwide income | Vietnam-sourced income only |
For most foreign English teachers employed full-time in Vietnam at language centers, international schools, bilingual programs, or universities, the 183-day threshold is crossed within a standard academic contract year. Once confirmed as a tax resident, the updated 2026 deductions significantly reduce the effective PIT burden: the self-deduction increased from VND 11,000,000 to VND 15,500,000 per month, and the dependent deduction from VND 4,400,000 to VND 6,200,000 per person per month under Personal Income Tax Law No. 109/2025/QH15.
Non-resident status applies primarily to visiting specialists, consultants, or short-term assignment teachers in Vietnam for under 183 days.
How Is PIT on Housing Allowance Calculated for Tax Residents?
For tax residents, employer-paid housing is first capped at 15% of other taxable income, added to total taxable income, reduced by applicable deductions (VND 15,500,000 self plus VND 6,200,000 per dependent under the 2026 rates), and then taxed at the 5-bracket progressive scale. The employer withholds the resulting PIT monthly and remits it to the General Department of Taxation.
Personal Income Tax Law No. 109/2025/QH15, effective 01 January 2026, restructured the progressive schedule from 7 brackets to 5, with rates as follows:
| Bracket | Monthly Taxable Income (VND) | Annual Taxable Income (VND) | Tax Rate |
|---|---|---|---|
| 1 | Up to 10,000,000 | Up to 120,000,000 | 5% |
| 2 | 10,000,001 to 30,000,000 | 120M to 360M | 10% |
| 3 | 30,000,001 to 60,000,000 | 360M to 720M | 20% |
| 4 | 60,000,001 to 100,000,000 | 720M to 1.2B | 30% |
| 5 | Over 100,000,000 | Over 1.2B | 35% |
Worked Example: Tax Resident, Gross Contract
Assumptions: monthly gross salary VND 50,000,000; employer pays VND 15,000,000 per month rent directly to landlord; no registered dependents; no Vietnamese social insurance deduction.
- Calculate the 15% housing cap: 15% x VND 50,000,000 = VND 7,500,000. Since actual rent (VND 15,000,000) exceeds the cap, taxable housing = VND 7,500,000.
- Total taxable income: VND 50,000,000 + VND 7,500,000 = VND 57,500,000
- Apply self-deduction: VND 57,500,000 minus VND 15,500,000 = VND 42,000,000 (PIT base)
- Apply progressive brackets:
| Bracket | Amount Taxed (VND) | Rate | Tax (VND) |
|---|---|---|---|
| Bracket 1 | 10,000,000 | 5% | 500,000 |
| Bracket 2 | 20,000,000 | 10% | 2,000,000 |
| Bracket 3 | 12,000,000 | 20% | 2,400,000 |
| Monthly PIT | 4,900,000 |
If the same employee’s rent were VND 5,000,000 (below the cap), the full VND 5,000,000 is taxable. Total taxable income = VND 55,000,000; after self-deduction VND 39,500,000; monthly PIT = VND 4,400,000. Despite paying VND 10,000,000 less in rent, the PIT difference is only VND 500,000 per month because the cap absorbed the excess in the first scenario.
How Is PIT on Housing Allowance Calculated for Non-Residents?
For non-resident foreign workers, the same 15% housing cap applies first. The combined taxable figure (salary plus capped housing) is then subject to a flat 20% PIT rate with no personal deductions whatsoever. This produces a simpler calculation but typically a higher effective tax burden compared to residents on moderate salaries.
Article 18.1 of Circular 111/2013/TT-BTC sets the non-resident employment income rate at 20% of Vietnam-sourced taxable income. No self-deduction, no dependent deduction, no social insurance deduction, and no tax treaty credit applies at the payroll withholding stage without additional filing steps.
| Item | Tax Resident | Non-Resident |
|---|---|---|
| 15% housing cap | Applied | Applied |
| Self-deduction | VND 15,500,000 per month | None |
| Dependent deduction | VND 6,200,000 per person per month | None |
| PIT rate on taxable income | 5%–35% progressive | 20% flat |
| Income scope | Worldwide | Vietnam-sourced only |
Worked Example: Non-Resident, Gross Contract
Assumptions: monthly Vietnam-sourced salary VND 80,000,000; employer pays VND 20,000,000 rent; no deductions applicable.
- Calculate the 15% housing cap: 15% x VND 80,000,000 = VND 12,000,000. Since actual rent (VND 20,000,000) exceeds the cap, taxable housing = VND 12,000,000.
- Total taxable income: VND 80,000,000 + VND 12,000,000 = VND 92,000,000
- Apply flat 20% rate: VND 92,000,000 x 20% = VND 18,400,000 per month
For comparison, if that same worker were classified as a tax resident and applied the VND 15,500,000 self-deduction, the PIT base would drop to VND 76,500,000. Running the 5-bracket calculation yields approximately VND 13,450,000 per month, a difference of nearly VND 5,000,000 per month from the non-resident flat rate. This is why confirming and documenting residency status early in an employment period is financially significant for both the worker and the employer.

Does a Gross or Net Salary Contract Change How Housing PIT Works?
Yes. The underlying PIT rules are identical in both cases, but the party absorbing the tax cost is different, and this changes the calculation sequence. Under a Gross contract, the employee bears the PIT, which is withheld from their stated salary. Under a Net contract, the employer commits to a guaranteed take-home figure and absorbs the PIT cost, requiring a gross-up process before the 15% housing cap and PIT rates can be applied.
Vietnamese tax guidance treats PIT paid by the employer under a Net contract as a benefit-in-kind forming part of the employee’s taxable employment income. The gross-up calculation is mandatory: the employer must first determine the gross income that would produce the agreed net pay after PIT, and the housing benefit is included in this calculation. The 15% housing cap applies to the grossed-up taxable income, not the contractual net figure.
| Item | Gross Contract | Net Contract |
|---|---|---|
| Salary stated in contract | Pre-tax (gross) | Post-tax (net, take-home) |
| PIT borne by | Employee (withheld from salary) | Employer (additional cost) |
| Housing cap base | Stated gross taxable income | Grossed-up taxable income |
| Gross-up calculation required | No | Yes |
| Total employer cost | Lower | Higher |
| Employee take-home predictability | Variable | Fixed |
| PIT calculation complexity | Standard | Requires iterative gross-up |
Under a Gross contract, the 15% housing cap is applied to the stated gross salary, PIT is calculated on the capped total minus deductions, and the result is withheld from the payslip. This is the standard structure for most foreign teacher employment contracts in Vietnam.
Under a Net contract, the employer works backwards from the agreed take-home pay to find the gross equivalent. Because the PIT the employer pays on the employee’s behalf itself becomes additional taxable income for that employee, the gross-up produces a compounding effect that increases the employer’s total tax cost beyond what a simple comparison of gross and net figures would suggest.
Frequently Asked Questions About Housing Allowance PIT in Vietnam
Is employer-paid housing always subject to PIT for foreign workers?
Yes, in almost all cases. Housing paid by the employer is taxable employment income for all foreign workers under Article 11 of Circular 111/2013/TT-BTC, with two narrow exceptions: employer-provided housing at industrial zones supplied free of charge to employees, and employer-built housing at areas classified as economically difficult or especially difficult under Vietnamese regional development policy. Standard rented apartments in major cities such as Ho Chi Minh City, Hanoi, or Da Nang do not qualify for either exemption.
What if actual rent is lower than the 15% ceiling?
The taxable housing amount is always the lesser of actual rent and the 15% ceiling. If the employer pays VND 4,000,000 per month in rent and the 15% cap on the employee’s other taxable income is VND 9,000,000, then only VND 4,000,000 enters the PIT base. The ceiling never inflates the taxable figure above what was actually paid for housing.
Does the housing PIT rule apply regardless of whether the foreign worker has a valid work permit?
Yes. PIT obligations are determined by income source and residency status, not work authorization status. A foreign worker whose employer pays housing costs is subject to the same PIT rules whether or not they hold a valid Vietnamese work permit. The absence of a work permit is a separate matter governed by Vietnamese labor law and carries its own administrative penalties, but it does not exempt the worker or employer from PIT compliance.
Can the employer also deduct housing costs from corporate income tax?
Yes, subject to documentation requirements. Under Circular 96/2015/TT-BTC as amended by Circular 25/2018/TT-BTC, employer-paid housing is a deductible corporate income tax expense when the housing benefit is clearly specified in the labor contract or the company’s internal salary and benefits policy, and when proper invoices and payment evidence exist. When renting from a company, required documents include the lease contract, VAT invoice, and payment confirmation. When renting from an individual landlord, required documents include the lease contract, payment receipts, and tax declaration evidence if the landlord’s annual rental income exceeds VND 100,000,000.
Is the VAT on employer-paid rent deductible for the company?
It depends on the foreign expert’s employment structure, per Article 14 of Circular 219/2013/TT-BTC. If the foreign expert works in Vietnam, holds a management role, and receives a salary from the Vietnamese entity, the input VAT on rent is not deductible but may be booked as a deductible corporate income tax expense. If the expert remains an employee of an overseas company, is dispatched to Vietnam under an intercompany agreement, and is paid by the foreign entity, the input VAT is deductible by the Vietnamese company, provided the written agreement between both entities explicitly states that the Vietnamese company bears the housing cost.
What changed about housing PIT with the 2026 tax reform?
The 15% housing cap itself remained unchanged. What changed under Personal Income Tax Law No. 109/2025/QH15, effective 01 January 2026, were the progressive tax brackets (reduced from 7 to 5) and the personal deductions: the self-deduction increased from VND 11,000,000 to VND 15,500,000 per month, and the dependent deduction increased from VND 4,400,000 to VND 6,200,000 per person per month. For tax-resident foreign workers, higher deductions reduce how much income reaches the upper brackets, which lowers the effective PIT rate on the housing portion without any change to how the taxable housing amount itself is determined.
Does the 15% cap apply to base salary only, or to the full pay including bonuses?
The 15% cap applies to the full total taxable income from wages and salary in that pay period, including base salary, performance bonuses, holiday bonuses, and other taxable allowances from the same employer. A month with a large bonus produces a higher 15% ceiling for that month. The cap is not limited to base salary alone.
