The Gross-to-Net Formula
Calculating your take-home pay in Vietnam involves three main deductions from your gross salary:
Net Salary = Gross Salary − Employee Insurance Contributions − Personal Income Tax
Employer Total Cost = Gross Salary + Employer Insurance Contributions + Trade Union Fund
The calculation differs slightly for Vietnamese employees vs foreign employees (mainly regarding unemployment insurance eligibility), and for tax residents vs non-residents (different PIT calculation method).
Step 1: Calculate Employee Insurance Contributions
Contribution Rates (from July 1, 2025)
| Insurance Fund | Vietnamese Employee | Foreign Employee |
|---|---|---|
| Social Insurance (SI) | 8% | 8% |
| Health Insurance (HI) | 1.5% | 1.5% |
| Unemployment Insurance (UI) | 1% | 0% (exempt) |
| Total | 10.5% | 9.5% |
Contribution Caps (2026)
Insurance contributions are capped — you don't pay on the full salary once you exceed the ceiling:
| Fund | Cap Basis | Cap Amount |
|---|---|---|
| SI + HI | 20 × reference level (VND 2,340,000) | VND 46,800,000/month |
| UI | 20 × regional minimum wage (Zone 1) | ~VND 106,200,000/month |
Practical impact: If your gross salary is VND 80,000,000/month, your SI and HI contributions are still calculated on VND 46,800,000, not VND 80,000,000.
2025 change: From July 1, 2025, the contribution base expanded to include base salary plus allowances and regular additional agreed payments. This may increase actual contributions for employees with large allowance components.
Calculation
For a foreign employee earning VND 80,000,000/month:
- SI: 8% × 46,800,000 = VND 3,744,000
- HI: 1.5% × 46,800,000 = VND 702,000
- UI: exempt (foreign employee)
- Total employee insurance: VND 4,446,000
Step 2: Calculate Assessable Income
Assessable income is the base on which PIT is calculated:
Assessable Income = Gross Salary − Employee Insurance Contributions − Personal Deduction − Dependant Deductions
Deductions (2026 rates)
| Deduction | Monthly Amount |
|---|---|
| Personal deduction (taxpayer) | VND 15,500,000 |
| Each qualifying dependant | VND 6,200,000 |
Non-residents: No deductions are available. PIT is calculated directly at 20% on gross income (no assessable income calculation needed).
Housing allowances: Included in assessable income but capped at 15% of other assessable income. Only the portion above this cap is taxable.
Step 3: Apply PIT Brackets
Progressive Brackets (2026, Tax Residents)
| Bracket | Monthly Taxable Income (VND) | Rate | Max Tax in Bracket |
|---|---|---|---|
| 1 | 0 – 10,000,000 | 5% | VND 500,000 |
| 2 | 10,000,001 – 30,000,000 | 10% | VND 2,000,000 |
| 3 | 30,000,001 – 60,000,000 | 20% | VND 6,000,000 |
| 4 | 60,000,001 – 100,000,000 | 30% | VND 12,000,000 |
| 5 | Over 100,000,000 | 35% | — |
Cumulative tax at each bracket ceiling:
- At VND 10M taxable: VND 500,000
- At VND 30M taxable: VND 2,500,000
- At VND 60M taxable: VND 8,500,000
- At VND 100M taxable: VND 20,500,000
Step 4: Your Net Salary
Net = Gross − Employee SI − Employee HI − Employee UI − PIT
That's it. All other benefits (employer contributions, trade union fund) come on top of gross and do not affect your net take-home pay.
Employer Cost Calculation
Your employer pays additional contributions on top of your gross salary:
| Contribution | Vietnamese Employee | Foreign Employee |
|---|---|---|
| Social Insurance (employer) | 17.5% | 17.5% |
| Health Insurance (employer) | 3% | 3% |
| Unemployment Insurance (employer) | 1% | 0% |
| Trade Union Fund | 2% | 2% |
| Total extra cost | 23.5% | 22.5% |
Employer contributions are capped at the same VND 46,800,000 base for SI and HI.
Total Cost to Employer = Gross Salary × (1 + 22.5%) (for foreign employees, capped)
Worked Examples
Example A: Foreign Tax Resident, VND 50,000,000 Gross, No Dependants (2026)
Step 1 — Employee Insurance:
- SI: 8% × 46,800,000 = 3,744,000
- HI: 1.5% × 46,800,000 = 702,000
- Total: VND 4,446,000
Step 2 — Assessable Income:
- 50,000,000 − 4,446,000 − 15,500,000 = VND 30,054,000
Step 3 — PIT:
- 5% × 10,000,000 = 500,000
- 10% × 20,054,000 = 2,005,400
- Total PIT: VND 2,505,400
Step 4 — Net Salary:
- 50,000,000 − 4,446,000 − 2,505,400 = VND 43,048,600
Employer additional cost:
- SI: 17.5% × 46,800,000 = 8,190,000
- HI: 3% × 46,800,000 = 1,404,000
- Trade Union: 2% × 50,000,000 = 1,000,000
- Total employer extra: VND 10,594,000
- Total cost to employer: VND 60,594,000
Example B: Foreign Non-Resident, VND 50,000,000 Gross
- PIT: 20% × 50,000,000 = 10,000,000
- (Insurance may still apply depending on contract type)
- Net salary: VND 40,000,000
Example C: Vietnamese Employee, VND 30,000,000 Gross, 2 Dependants (2026)
Step 1 — Employee Insurance:
- SI: 8% × 30,000,000 = 2,400,000
- HI: 1.5% × 30,000,000 = 450,000
- UI: 1% × 20 × Zone 1 min wage (5,310,000) = 1% × 106,200,000 cap → 1% × 30,000,000 = 300,000
- Total: VND 3,150,000
Step 2 — Assessable Income:
- 30,000,000 − 3,150,000 − 15,500,000 − (2 × 6,200,000) = VND −1,050,000
- Result is negative → no PIT due
Net Salary: VND 26,850,000 (0 PIT)
This illustrates the powerful effect of the 2026 deduction increases — many middle-income earners with dependants owe zero PIT.
Net-to-Gross (Reverse Calculation)
If you need to work backwards from a target net salary (common when negotiating offers), the calculation is complex because:
- Insurance contributions have caps that create non-linearity
- PIT brackets create step-changes in the effective rate
The correct approach is binary search or iterative calculation:
- Estimate a gross salary
- Calculate net from that gross using the steps above
- Adjust up or down until the calculated net matches your target
Our [Tax Calculator](/calculator) handles this automatically — enter your target net salary and select "Net → Gross" mode.
Rough rules of thumb (2026, foreign resident, no dependants):
- Net VND 30M ≈ Gross VND 40M
- Net VND 50M ≈ Gross VND 65M
- Net VND 80M ≈ Gross VND 105M
Actual results vary with dependants, allowances, and residency status.
