Total social insurance burden reaches 32% of gross salary in Vietnam (employer contributes 21.5%, employee contributes 10.5%) under the framework of Vietnam labor law and FDI compliance and the 2024 Social Insurance Law (Law 41/2024/QH15, effective from July 1, 2025) and detailed implementing guidance applied in 2026. Since January 1, 2026, the Region I minimum wage has been VND 5,310,000 (~USD 210) under Decree 293/2025/ND-CP, and payroll systems must apply it as the practical floor for contribution bases. Pay cannot be set below the regional minimum wage, so contribution bases follow it upward.
Vietnam maintains only a single bilateral social insurance agreement, so virtually all foreign hires on contracts of 12 months or more must participate in mandatory Social Insurance (SI) and Health Insurance (HI). VSS audits assess both employer and employee portions plus statutory late-payment interest on unpaid balances.
This guide covers 2026 SHUI rates, contribution floors and ceilings, and the payment deadlines that trigger most FDI compliance gaps. For the full picture of employer obligations beyond SHUI, see Vietnam employment law and HR compliance for FDI companies.
1. Mandatory Social Insurance System in Vietnam
Vietnam operates a mandatory Social/Health/Unemployment Insurance (“SHUI”) system that applies to FDI employers from the first day of the labor contract, there is no grace period, size threshold, or sector exemption for foreign-invested companies.
- Social Insurance (SI) funds retirement pensions, maternity leave, sickness benefits, and occupational injury compensation. Both Vietnamese and foreign employees on Vietnam labor contracts must participate.
- Health Insurance (HI) grants access to public healthcare at registered facilities. Applies to all employees regardless of nationality.
- Unemployment Insurance (UI) provides job-loss benefits for Vietnamese employees only. Foreign workers are exempt from UI contributions under current rules.
Foreign employees on fixed-term Vietnamese labor contracts of 12 months or more must participate in SI and HI; only UI remains restricted to Vietnamese nationals. Registration must be completed within 30 days of the date the employee becomes subject to participation. People working under a probationary contract are not yet subject to compulsory social insurance (under Decree 158/2025/ND-CP); if probation is a clause inside a labor contract, the position depends on the contract type signed.
2. Statutory SHUI Contribution Rates and Salary Base Composition in 2026
You shoulder 21.5% of the contribution base across three mandatory programs, while your employees contribute 10.5%, per the rate structure under the 2024 Social Insurance Law and its implementing guidance.
| Program | Employer Rate | Employee Rate | Total |
|---|---|---|---|
| Social Insurance | 17.5% | 8% | 25.5% |
| Health Insurance | 3% | 1.5% | 4.5% |
| Unemployment Insurance | 1% | 1% | 2% |
| Combined Total | 21.5% | 10.5% | 32% |
Non-Salaried Managers
Enterprise managers who do not draw a salary contribute for themselves at 25% (3% to the sickness and maternity fund, 22% to the retirement and survivorship fund) on a contribution base they choose between the reference level and 20 times that level, under Articles 31 and 33 of the Social Insurance Law.
The contribution base comprises the contractual basic wage, fixed job-related allowances (position, responsibility, hazardous working conditions, seniority, regional allowances), and other predetermined regular supplements. Under Article 7(1) of Decree 158/2025/ND-CP, the base covers pay by job or title, salary allowances and other supplements with a specific amount, stated in the labor contract and paid regularly and consistently each pay period. Amounts that depend on or vary with productivity, work process or work quality (such as performance bonuses) are outside the base. Other items such as gasoline, telephone or housing support need a case-by-case check: if the contract states a specific amount and it is paid regularly, it can fall inside the base.
Employment contracts must itemize gross salary separately from allowances, lump-sum compensation without breakdown gets challenged during audits. You also need signed salary adjustment notices when pay increases occur, timesheets for overtime calculations, and allowance payment records with recipient signatures.
A frequent pitfall for FDI employers is executing net salary contracts without specifying gross pay, forcing retroactive gross-up calculations and higher contribution bases during VSS audits.
3. Contribution Floor Based on Regional Minimum Wage
Vietnam’s regional minimum wages increase across all four regions from January 1, 2026, under Decree 293/2025/ND-CP. Pay cannot be set below these levels, so they act as a practical floor for SHUI contribution bases.
| Region | Monthly Minimum (2026) | USD Equivalent | Min. Employer SHUI (21.5%) |
|---|---|---|---|
| Region I (Hanoi, HCMC) | VND 5,310,000 | ~USD 210 | VND 1,141,650 |
| Region II | VND 4,730,000 | ~USD 187 | VND 1,016,950 |
| Region III | VND 4,140,000 | ~USD 164 | VND 890,100 |
| Region IV | VND 3,700,000 | ~USD 146 | VND 795,500 |
Paying below regional minimums during inspections triggers administrative penalties under the applicable sanctioning decree, and VSS recalculates contributions using the regional floor retroactively.
For an FDI company in Ho Chi Minh City, the minimum salary and SHUI contribution base for each eligible employee is at least VND 5,310,000 (~USD 210) from January 1, 2026.
The 2026 regional minimum wage increase affects more than SHUI floors, see Vietnam’s 2026 minimum wage rates and employer compliance impact for full regional breakdowns and overtime multiplier changes.

4. Statutory Contribution Ceilings under the Reference Level
The “Reference Level” (or base salary benchmark) is a government-determined statutory standard, distinct from the regional minimum wage, used to cap social insurance contributions and benchmark welfare benefits.
The year 2026 features a two-stage adjustment under the Government’s wage reform roadmap:
- Phase 1 (Prior to July 1, 2026): The Reference Level sits at VND 2,340,000/month (Decree 73/2024/ND-CP). Social and health insurance contributions are capped at 20 times this amount: VND 46,800,000/month (~USD 1,850).
- Phase 2 (Effective July 1, 2026 onward): The Reference Level increases to VND 2,530,000/month, equal to the base salary set by Decree 161/2026/ND-CP. The SI/HI contribution ceiling correspondingly rises to 20 times this level: VND 50,600,000/month (~USD 2,000).
- Unemployment Insurance (UI) Cap: Capped separately at 20 times the regional minimum wage, for Region I (Hanoi, HCMC): 20 × VND 5,310,000 = VND 106,200,000/month (~USD 4,200) throughout 2026 (Decree 293/2025/ND-CP).
Comparative Cap Impact for an Executive Earning VND 150,000,000/month
Consider a senior manager or foreign executive at an FDI enterprise in HCMC earning VND 150,000,000/month:
| Effective Period | Statutory SI/HI Contribution Cap | Max Employer Contribution | Max Employee Deduction | Total Monthly Max Remittance |
|---|---|---|---|---|
| Prior to July 1, 2026 | Cap VND 46,800,000 (Reference Level: 2.34M) |
VND 10,656,000 (SI+HI: 9,594,000 + UI: 1,062,000) |
VND 5,508,000 (SI+HI: 4,446,000 + UI: 1,062,000) |
VND 16,164,000/mo |
| From July 1, 2026 onward | Cap VND 50,600,000 (Reference Level: 2.53M) |
VND 11,435,000 (SI+HI: 10,373,000 + UI: 1,062,000) |
VND 5,869,000 (SI+HI: 4,807,000 + UI: 1,062,000) |
VND 17,304,000/mo |
| Net Variance | +VND 3,800,000 cap base | +VND 779,000/month | +VND 361,000/month | +VND 1,140,000/month |
Key Takeaway for FDI Payroll & HR Directors:
- Prior to July 1, 2026, an employee earning VND 150 million has only VND 5,508,000/month deducted (3.67% of salary). Employer cost is capped at VND 10,656,000/month (7.1% of salary).
- From July 1, 2026, employee deductions adjust to VND 5,869,000/month (3.91% of salary), and employer contributions adjust to VND 11,435,000/month (7.6% of salary).
- All income exceeding the statutory cap (surplus above 46.8M prior to July 1, and above 50.6M from July 1) is completely exempt from statutory SI and HI deductions.
⚠️ COMPLIANCE ALERT: The Reference Level is the basis for both the lowest contribution base and the ceiling (20 times). The regional minimum wage is the practical floor because pay cannot be set below it. Do not confuse the two benchmarks when declaring contribution bases.
5. Mandatory Social Insurance Rules for Expatriates
Most FDI companies assume bilateral agreements exempt their expats from Vietnamese social insurance. Every expat working in Vietnam under a fixed-term labor contract of 12 months or longer must participate in compulsory social insurance (Article 2 of the Social Insurance Law), at the same rates and contribution base rules as Vietnamese employees, while remaining outside unemployment insurance under current implementing rules. The exceptions are intra-corporate transfers, persons already at retirement age when signing the contract, and cases an international treaty provides otherwise.
For an expat earning VND 80 million (~USD 3,170) monthly, the contribution base is capped at VND 50,600,000 from July 1, 2026 (VND 46,800,000 before that date), so you pay VND 10,373,000 (~USD 410) in employer SI/HI each month, or VND 124,476,000 (~USD 4,930) annually per expat position (20.5% x VND 50,600,000 x 12).
Since work permit status directly determines SHUI participation scope, confirm permit classification against Vietnam work permit requirements and FDI compliance procedures before setting contribution levels. Expats departing Vietnam must also coordinate SI refund timing with personal income tax finalization under the 183-day residency rules.
For FDI enterprises employing multiple foreign nationals or maintaining multi-provincial branches, establishing compliant social insurance contribution bases upon initial contract execution is vital. Foreign employee filing irregularities frequently trigger cross-audits encompassing corporate income tax deductions and expatriate personal income tax finalizations.
6. Statutory Payment Deadlines, Audit Risks, and Sanctions Matrix
SHUI contributions must be remitted by the last day of the month following the salary payment period, per VSS implementing instructions. Any payment after the deadline triggers the daily amount (currently 0.03%) on the overdue sum under Article 40 of Law 41/2024/QH15. For VND 50 million (~USD 1,980) in monthly SHUI obligations, a 10-day delay adds a VND 150,000 late-payment charge. Systematic delays across 12 months generate VND 1.8 million (~USD 71) in unnecessary expenses.
The compliance cycle comprises three steps: employee registration with VSS within 30 days of the date the employee becomes subject to participation, monthly declarations via the VSS portal, and bank remittance. Failure to register within 30 days does not extinguish the debt; contributions remain payable from the date participation began.
For budget planning, calculate your total annual SHUI obligation as: (average gross salary per employee × 32% × headcount × 12 months). A 20-person team at VND 15 million (~USD 594) average gross salary generates VND 1,152,000,000 (~USD 45,600) in annual SHUI costs. Build this into your financial projections before hiring, because budgeting on net salary alone can understate total employment cost. Note that SHUI contributions continue during public holidays and paid leave, the contribution base does not reduce for holiday months.
Contract type and duration affect both registration deadlines and contribution scope, review Vietnam labor contract types, probation rules, and hiring compliance to align SHUI setup with contract structure.
VSS audits can result in back-payment demands covering both the employer and employee portions for the entire underpayment period. VSS treats your failure to withhold employee contributions as your liability.
Typical violations in FDI payrolls: using net salary instead of gross as the contribution base, excluding regular allowances that should be included, applying the wrong regional minimum, and failing to update bases when salaries increase.
Statutory administrative sanctions under Decree 283/2026/ND-CP (effective September 10, 2026, replacing Decree 12/2022/ND-CP; the rates below are as written in the decree (individual level), and organizations are fined twice that):
- Late payment or under-remittance of the amount due: Fined 12% to 15% of the total overdue amount (capped at VND 75,000,000), plus compulsory retroactive remittance of unpaid principal and statutory late interest of 0.03%/day.
- Evasion of social insurance contributions (Article 44): Fined 18% to 20% of the evaded amount, capped at VND 75,000,000, plus full recovery of evaded contributions and 0.03%/day interest. Evasion lasting 6 months or more, from VND 50,000,000 or involving 10 or more workers, that continues after a prior administrative penalty triggers criminal liability under Article 216 of the Penal Code 2015, with corporate fines of VND 200 million to 3 billion depending on scale.
Beyond SHUI, the contribution base determines trade union fee obligations calculated on the social insurance salary base, and audit findings directly spill over into PIT and corporate tax assessments. Furthermore, headcount discrepancies from improper terminations compound inspection liabilities; consult our guide on employee termination legal grounds and severance calculation procedures to maintain audit-ready payroll records.
