Net Salary Contracts for Expatriates in Vietnam: How Gross-Up Works for PIT and Insurance
Under a net salary contract in Vietnam, the agreed amount may be after PIT only or after both PIT and employee insurance. The distinction must be written down before gross-up. Article 46(4) of Decree No. 253/2026/ND-CP provides the conversion method for employment income stated without PIT. For resident employment income, the relevant 2026 rules apply from the 2026 tax period; the decree took effect on 1 July 2026 (Article 69). Under Article 70(2), monthly or quarterly returns already filed for 2026 before that date are not refiled; any difference is adjusted in the 2026 annual finalisation.

This guide explains the conversion base, distinguishes income before deductions from assessable income after deductions, provides a derived five-bracket conversion table, and shows how to reconcile a net salary contract in Vietnam with employee insurance. It uses sources checked on 3 November 2026. The worked example covers a salary stated after PIT but before employee insurance. Housing and tax equalisation require separate calculations and are outside that example.
Net vs gross: what a net salary contract in Vietnam really promises
A gross contract states salary before PIT and the employee’s compulsory insurance. A net salary contract in Vietnam must specify which deductions the promised amount already excludes. An undertaking to pay a salary after PIT is different from an undertaking to deliver a fixed bank transfer after PIT and insurance. The example below uses the first definition, and shows the employee’s final take-home amount separately.
The PIT rules expressly address salaries stated without PIT, which is how a net salary contract in Vietnam is treated for tax. The employment agreement still needs to comply with labour law. For tax purposes, first classify the salary and each benefit; not every payment made for an employee is taxable. Exclude qualifying non-taxable or exempt amounts before applying the conversion, and keep the evidence supporting the classification. The conversion is addressed in Article 46(4) of Decree No. 253/2026/ND-CP.
The legal formula for a net salary contract in Vietnam under Decree No. 253/2026/ND-CP
For a resident employee paid under a net salary contract in Vietnam, Article 46(4)(a)–(b) of Decree No. 253/2026/ND-CP specifies the base used for conversion. In the terminology used here, income before deductions corresponds to “thu nhập chịu thuế”; assessable income after deductions corresponds to “thu nhập tính thuế”. Keeping those labels separate prevents a second deduction of the same amount at finalisation.
| Component | Treatment | Legal basis |
|---|---|---|
| Net income actually received | Salary not including tax that the employee receives each month, excluding amounts that are not taxable and income that is exempt | Article 46(4)(b), Decree No. 253/2026/ND-CP |
| Plus: amounts paid on the employee’s behalf | Include only benefits classified as taxable under the decree. For housing, apply the specific cap and exclusions; do not assume that every school fee, flight or other benefit is taxable. | Article 8; Article 46(4)(a)–(b), Decree No. 253/2026/ND-CP |
| Minus: deductions | Use only eligible, evidenced deductions. Apply the separate conditions and limits for family deductions, insurance, pensions, life insurance and other deductions. | Article 46(2), (4); Articles 47–49, Decree No. 253/2026/ND-CP |
| Equals: base for conversion | Convert the base into assessable income after deductions; apply the resident progressive schedule. | Article 46(4), Decree No. 253/2026/ND-CP; Article 9 of the Law on Personal Income Tax No. 109/2025/QH15 |
Article 46(4)(a) of Decree No. 253/2026/ND-CP excludes hypothetical tax and hypothetical housing amounts under the stated employer policy, which matters when a net salary contract in Vietnam sits within a tax equalisation programme. For finalisation, Article 46(4)(c) refers to annual income before deductions determined from the monthly converted figures, including income at multiple payers. Do not merely add monthly assessable income and then deduct annual allowances again. Keep a monthly reconciliation of converted assessable income, the relevant deductions and income before deductions.
Conversion table for a net salary contract in Vietnam
This table is an algebraic conversion derived from Article 9 of the Law on Personal Income Tax No. 109/2025/QH15, as amended by Law No. 09/2026/QH16 (consolidated text No. 112/VBHN-VPQH), not an official statutory conversion appendix. Amounts are in VND million per month. “Base” means the amount available after PIT and after the deductions already accounted for in the conversion base; it is not automatically the salary written in the contract. Use it only after establishing resident status and classifying the income and deductions for the net salary contract in Vietnam. The conversion method is addressed in Article 46(4) of Decree No. 253/2026/ND-CP.
| Bracket | Monthly base after deductions (VND million) | Assessable income after deductions (VND million) | Rate on the top slice |
|---|---|---|---|
| 1 | Up to 9.5 | Base ÷ 0.95 | 5% |
| 2 | Over 9.5 to 27.5 | (Base − 0.5) ÷ 0.9 | 10% |
| 3 | Over 27.5 to 51.5 | (Base − 3.5) ÷ 0.8 | 20% |
| 4 | Over 51.5 to 79.5 | (Base − 9.5) ÷ 0.7 | 30% |
| 5 | Over 79.5 | (Base − 14.5) ÷ 0.65 | 35% |
For a positive base, the PIT borne under the net salary contract in Vietnam equals converted assessable income minus the base. If there is no positive assessable amount, do not force a negative input through the table. The bracket limits are VND 10, 30, 60 and 100 million of monthly assessable income. The personal deduction is VND 15.5 million per month, with VND 6.2 million for each qualifying dependant. Eligibility and supporting records remain necessary. The bracket limits and family deductions are set out in Articles 9 and 10 of the Law on Personal Income Tax No. 109/2025/QH15.
Worked example: a net salary contract in Vietnam after PIT only
Hypothetical example: an expatriate manager is a Vietnamese tax resident, has no dependants and receives no taxable benefits in kind in this example. Her net salary contract in Vietnam promises VND 80 million after PIT but before the employee’s insurance is withheld. Assume she is within compulsory social and health insurance, outside the statutory exceptions, and her insurable salary reaches the applicable ceiling. The combined employee contribution used here is VND 4.807 million. The insurance assumptions use the Social Insurance Law No. 41/2024/QH15, Decree No. 188/2025/ND-CP and the July 2026 level under Decree No. 161/2026/ND-CP.
| Line | VND million | Explanation |
|---|---|---|
| Salary after PIT, before employee insurance | 80.000 | Definition agreed in this example |
| Less: employee compulsory insurance | 4.807 | 8% BHXH plus 1.5% BHYT on VND 50.6 million, under the example assumptions |
| Less: personal deduction | 15.500 | No dependant deduction assumed |
| Conversion base | 59.693 | 80 − 4.807 − 15.5 |
| Assessable income after deductions | 71.704 | (59.693 − 9.5) ÷ 0.7 |
| PIT borne through gross-up | 12.011 | 71.7042857 − 59.693 |
| Gross cash salary before deductions | 92.011 | 80 + 12.0112857 |
| Final cash take-home | 75.193 | 92.0112857 − 12.0112857 − 4.807 |
The result reconciles the net salary contract in Vietnam: gross cash salary less PIT equals VND 80 million, and the employee receives VND 75.193 million after insurance. The employer’s own statutory contributions are additional and are not included in the gross cash salary above. All calculations retain full precision until the presentation stage. A net salary contract in Vietnam that promises VND 80 million after both PIT and insurance would require a different calculation; it must not reuse these numbers.
Insurance under a net salary contract in Vietnam
Insurance eligibility is separate from tax residence. Article 2(2) of the Social Insurance Law No. 41/2024/QH15 covers foreign employees on qualifying fixed-term contracts of at least 12 months, subject to its exceptions: intra-company transfers, retirement-age cases at contract conclusion and different treaty provisions. Do not determine coverage solely from the words “expatriate” or “net salary contract in Vietnam”. Check health-insurance eligibility independently. For coverage details, see our guide to social insurance for foreign employees.
For an employee within both schemes, Article 33(1)(a) of the Social Insurance Law No. 41/2024/QH15 sets the employee BHXH contribution at 8%; Article 6(1)(a) of Decree No. 188/2025/ND-CP sets the relevant BHYT contribution at 4.5%, split two-thirds employer and one-third employee. The combined employee rate in the example is therefore 9.5%.
The BHXH ceiling is 20 times the reference level under Article 31(1), and Article 141(13) of the same law sets the reference level equal to the statutory base salary until the base salary is abolished. Using the VND 2.53 million base salary from 1 July 2026 gives VND 50.6 million; confirm the relevant basis and period before applying it to a real payroll. The VND 2.53 million level is provided under Decree No. 161/2026/ND-CP.
For a net salary contract in Vietnam, record how the insurable salary is determined under the law, alongside the agreed tax and insurance allocation. Writing a gross figure into the contract does not override statutory inclusion rules. Confirm the regular salary components, the applicable ceiling and any special treatment rather than assuming the ceiling applies to every foreign employee. The insurance base must follow Article 31 of the Social Insurance Law No. 41/2024/QH15 and the applicable health-insurance rules under Decree No. 188/2025/ND-CP.
Non-residents on a net salary contract in Vietnam: a simpler conversion
For a non-resident with taxable employment income attributable to work in Vietnam, Article 21 of the Law on Personal Income Tax No. 109/2025/QH15 and Article 64 of Decree No. 253/2026/ND-CP provide the 20% basis. For a simple net salary contract in Vietnam paid after PIT only, with no other taxable benefits or adjustments, VND 50 million ÷ 0.8 gives VND 62.5 million before PIT and VND 12.5 million PIT. Do not apply that shortcut to a package with additional benefits without first determining the full taxable income. Tax residence and any applicable treaty relief must be assessed separately.
Foreign currency and benefits in kind in a net salary contract in Vietnam
Article 17(1) of Decree No. 253/2026/ND-CP uses the buying rate of the commercial bank where the individual maintains the transaction account or where the payer maintains the account used for payment, at the time income arises. Where the organisation or individual has no account in Vietnam, the provision instead refers to the State Bank’s relevant central or cross exchange rate. Under a net salary contract in Vietnam set in foreign currency, record the date, currency, bank and rate used for each payment.
Under Article 17(2), non-cash taxable income is valued in VND using the ordinary transaction value of the product or service, or a comparable equivalent, when the income arises. This valuation step is different from deciding whether the benefit is taxable in the first place. Review both questions before inserting a value into the gross-up for a net salary contract in Vietnam.
For employer-paid housing, Article 46(4)(a) of Decree No. 253/2026/ND-CP applies an actual-payment limit of 15% of the specified income-before-deductions base. That comparison excludes the actual rent, electricity, water and accompanying services, and hypothetical housing where relevant. Calculate the housing inclusion and conversion consistently; do not treat 15% as an extra deduction or insert the full package automatically. Housing is excluded from the numerical example above; see our guide to employer-paid housing before adding rent to a net salary contract in Vietnam.
Setting up payroll for a net salary contract in Vietnam: a checklist
In our professional view, many gross-up errors start with information that was not written down when the expatriate joined. Before the first pay run under a net salary contract in Vietnam, agree and record the following:
- The net amount, its currency and whether it is after tax only or after tax and the employee’s insurance.
- Every benefit the employer will pay, the invoice recipient, the tax classification and any exemption or cap; do not assume all school fees or home-leave flights are taxable.
- Whether a tax equalisation policy applies and how the hypothetical tax and hypothetical housing amounts are calculated, so they can be excluded from the base.
- The lawful insurable salary and coverage decision, with the employee and employer contributions recorded separately.
- The employee’s arrival date, lease and expected days in Vietnam, so the payroll can apply the right residence status from the first month.
- Registered dependants, with the documents needed for the family deduction.
With those records, prepare a monthly reconciliation for the net salary contract in Vietnam. Keep the promised amount, taxable benefit inclusions, employee insurance, deductions, conversion base, assessable income, PIT and final bank transfer in separate fields. A second person should be able to reproduce the arithmetic from the contract and supporting documents without guessing what “net” means.
6 mistakes to avoid with a net salary contract in Vietnam
In our professional view, these are the errors most worth checking in a net salary contract in Vietnam:
- Failing to classify each benefit before gross-up, or automatically taxing a benefit that qualifies for non-taxable or exempt treatment.
- Including the hypothetical tax or hypothetical housing deduction of a tax equalisation policy in the base, which Decree No. 253/2026/ND-CP excludes.
- Applying the progressive table to a non-resident, or the flat 20% to an employee who has become a resident.
- Assuming a contractual net amount is the statutory insurance base without checking the applicable insurance rules.
- Fixing the VND gross-up once for a salary set in foreign currency instead of converting each month.
- Confusing annual income before deductions with assessable income after deductions, or deducting the same allowance twice at finalisation.
Frequently asked questions about a net salary contract in Vietnam
Is a net salary contract in Vietnam recognised for PIT purposes?
The tax rules expressly provide for conversion of salaries stated without PIT. The employment terms must also comply with the applicable labour law. The PIT conversion is addressed in Article 46(4) of Decree No. 253/2026/ND-CP.
Who files the tax under a net salary contract in Vietnam?
The employer withholds and declares the tax as for any employee, calculating it on the converted amount. The employee remains the taxpayer.
Does this guide decide corporate income tax deductibility?
No. It explains the employee PIT conversion and excludes a corporate income tax conclusion. Deductibility requires its own legal basis and supporting documents.
Do family deductions apply to a net salary contract in Vietnam?
Yes, for residents. They are subtracted before the conversion, as the formula in Clause 4, Article 46 of Decree No. 253/2026/ND-CP shows.
What if an employee on a net salary contract in Vietnam has two employers?
Retain monthly gross-up records for each payer. Article 46(4)(c) of Decree No. 253/2026/ND-CP addresses annual income before deductions across those payers; do not simply sum post-deduction assessable amounts and apply a second annual deduction.
Should we use gross or net contracts for expatriates?
It depends on the assignment policy. A net salary contract in Vietnam protects the employee’s take-home pay but moves exchange-rate and tax-rate risk to the employer.
