The difference between net pay vs gross pay in Vietnam can exceed 10-20% of an employee’s salary once social insurance contributions and personal income tax are applied.
This guide from terra explains what gross pay and net pay mean under Vietnamese law, walks through the full deduction chain with 2025 rates, covers net salary contracts and their risks, and includes a complete gross-to-net work example in VND.
| Question | Quick Answer |
| What is gross pay? | The full salary agreed in the labor contract, before any deductions are applied. |
| What is net pay? | The amount the employee actually receives after SHUI contributions and PIT withholding. |
| What is deducted from gross pay? | Employee SHUI at 10.5% of gross (8% SI + 1.5% HI + 1% UI) and PIT at progressive rates. |
| Vietnam law defaults to gross or net? | Gross salary. All labor obligations in Vietnam are structured around gross pay. |
| Can a company offer a net salary contract? | Yes, but the employer bears PIT risk and complexity. |
| What is the employer cost above gross? | Approximately 21.5% in mandatory SHUI contributions. |
What is Gross Pay?
Gross pay is the total salary agreed between employer and employee in the labor contract, before any deductions are applied. In Vietnam, gross salary is the legal baseline for all payroll obligations: SHUI contribution calculations, PIT withholding, minimum wage compliance, overtime rate calculations, and pro rata adjustments when an employee joins or leaves mid-month.

Under Article 90, Labor Code 2019, wages include the salary rate for the job or position, salary allowances, and other supplements agreed to be paid regularly and stably in each pay period. Not everything an employee receives is part of this gross pay definition.
Understanding gross pay meaning matters because SHUI contributions and PIT are both calculated on the gross salary base. Misclassifying allowances as inside or outside the base directly affects both employer contributions and employee deductions.
What counts as gross salary under Vietnamese law?
| Inside SHUI base (Gross) | Outside SHUI base (Strictly limited) |
| Base salary for the role | Meal allowance (capped per state regs) |
| Position/Seniority allowances | Birthday/Wedding/Funeral allowances |
| All regular monthly supplements | Benefits not associated with work performance |
| Performance bonuses (if fixed in contract) | Direct housing/gas allowances must be non-regular to stay outside base. |
What is Net Pay?
Net pay is the amount an employee actually receives in their bank account after all mandatory deductions have been applied to gross pay. In Vietnam, the two deduction categories are employee SHUI contributions and Personal Income Tax. For most employees earning between VND 15 and 30 million gross, net pay typically runs 80 to 88% of gross pay.

The gap between gross pay and net pay varies significantly by income level. A lower earner with two dependents paying minimal PIT may take home close to 90% of gross. A senior manager earning above VND 50 million gross may see net pay fall to 70% or below once progressive PIT reaches 25 to 30%. Take home pay depends heavily on declared dependents and applicable deductions.
What is deducted from gross pay to arrive at net pay?
| Deduction | Employee rate | Cap |
| Social Insurance (SI) | 8.0% | VND 46,800,000/month from July 2025 |
| Health Insurance (HI) | 1.5% | Same cap |
| Unemployment Insurance (UI) | 1.0% | Regional minimum wage x 20 |
| Total employee SHUI | 10.5% | SI/HI: 46.8M VND; UI: regional minimum wage × 20 |
| Personal Income Tax (PIT) | 5% to 35% | Applied to taxable income after deductions |

What is the total employer cost above gross salary?
Gross salary is not the total cost of employment. Employer SHUI contributions add approximately 21.5% above gross pay. The formula for Total CTC:
| Total employer CTC = Gross salary x 1.215 |
| Employer contribution | Rate |
| Social Insurance | 17.5% |
| Health Insurance | 3.0% |
| Unemployment Insurance | 1.0% |
| Trade Union Fund | 2.0% |
| Total | ~21.5% |

Net Salary Contracts in Vietnam: What FDI Companies Need to Know
Many FDI companies express senior and expat packages as net figures. Vietnamese law does not define net salary contracts but does not prohibit them. Operating on a net salary Vietnam contract creates three specific risks every FDI finance team should understand before agreeing to a net salary offer.
How a net salary contract works in Vietnam
When an employee is offered VND 20,000,000 net, the employer must gross-up the salary to determine actual payment. At that income level with one dependent, the gross equivalent exceeds VND 22,500,000. The employer pays PIT on behalf of the employee, bears that cost, but any PIT refund at annual finalization goes to the employee, not back to the employer.
This creates cost unpredictability whenever PIT rates, personal deductions, or family situations change. A new dependent declared by the employee generates a refund that flows to the employee even though the employer has been paying PIT all year. For full expat package structuring, see payroll for expats in Vietnam.
Risk 1: Cost unpredictability. Any change in PIT law or personal deductions shifts the employer cost without warning.
Risk 2: Refund flows to employees. Overpaid tax is returned to the employee despite the employer bearing the tax cost.
Risk 3: SHUI base complications. Contributions must still be calculated on gross equivalent amounts, requiring accurate gross-up every month.
Net pay vs gross pay for bonus and leave calculations
Bonus payments interact with gross pay and net pay differently depending on how they are structured. Regular bonuses paid monthly are generally part of the SHUI base and PIT base. Year-end or irregular performance bonuses are typically excluded from the SHUI base but remain subject to PIT as annual taxable income. For the detailed calculation bonus methodology see the dedicated article.
For pro rata salary calculations during partial months, the gross salary figure is the correct input to the formula. Net pay is never used as the basis for pro rata calculations. See the pro rata article for a complete worked example.
Data Protection and Salary Confidentiality in Vietnam
Gross and net salary data are classified as sensitive personal data under Decree 356/2025/ND-CP on personal data protection, effective January 1, 2026. Employers must protect payroll data with technical controls, restrict access to authorized personnel, and maintain processing records.
For FDI companies sharing payroll data with overseas HQ for group reporting, data transfer obligations under Decree 356 apply. See the data protection payroll article for compliance steps.
FAQ: Net Pay vs Gross Pay in Vietnam
Questions covering what HR and finance teams most commonly ask about gross and net salary in Vietnam.
Is gross or net salary stated in the labor contract in Vietnam?
Gross salary. Vietnamese law structures all contractual and statutory obligations around gross pay. A net salary contract must explicitly state the figure is net and that the employer bears PIT. Without that explicit statement, any salary figure in a contract is treated as gross.
How does gross pay affect social insurance in Vietnam?
SHUI contributions for both employer and employee are calculated on gross salary up to the cap of VND 46,800,000/month from July 2025. A higher gross means higher contributions from both parties until the cap is reached. Above the cap, additional salary does not increase SHUI amounts.
What is the difference between gross salary Vietnam and CTC?
CTC (Cost to Company) equals gross pay plus employer SHUI contributions of approximately 21.5%. For a VND 20,000,000 gross salary, CTC is approximately VND 24,300,000. Always model CTC not gross salary when preparing headcount budgets.
Does overtime affect gross pay and take home pay in Vietnam?
Overtime pay adds to gross pay for PIT purposes but is excluded from the SHUI base per Decree 145/2020/ND-CP. For PIT, the premium portion above the regular rate is tax-exempt. The base-equivalent portion of overtime remains taxable as part of annual gross income.
What net pay calculation applies to foreign employees in Vietnam?
The same gross-to-net deduction chain applies. Foreign employees contribute to SI and HI at the same rates as Vietnamese staff for contracts of 12 months or more, but are exempt from Unemployment Insurance. They are subject to PIT on Vietnam-sourced income as either residents (progressive rates) or non-residents (flat 20% rate if below 183 days in Vietnam per tax year).
Is it legal to pay employees a different amount than stated in the contract?
The net pay received will always differ from the gross stated in the contract because of mandatory deductions. That is legal and expected. What is not legal is paying less than the gross amount stated, which would violate Article 94 of the Labor Code 2019 and minimum wage regulations.
How can employees verify their net pay calculation is correct?
Employees should receive a payslip each cycle showing gross pay, each deduction individually itemized, and net pay. They can verify by applying the current SHUI rates and PIT formula to their gross salary and comparing the result. terra provides bilingual payslips that show each calculation step clearly.
