Vietnam's social insurance system (administered by Vietnam Social Security, VSS) is mandatory for employees under Vietnamese labor contracts, including foreign employees since 2018 reforms extended coverage to foreign workers. It comprises three linked schemes: Social Insurance (covering sickness, maternity, work injury/occupational disease, retirement pension, and survivor benefits), Health Insurance (BHYT), and Unemployment Insurance. Combined employer and employee contributions total roughly 32% of gross salary (subject to a statutory salary cap for contribution purposes), split with the employer bearing the larger share (~21.5%) and the employee (~10.5%).
Foreign employees who leave Vietnam permanently can claim a one-time social insurance payout (rather than a small monthly pension abroad, which is impractical), but the claims process requires specific documentation and timing — most departing expats don't realize this benefit exists or miss the window to claim it efficiently.
Key Facts
Contribution split: employer pays roughly 17.5% (social insurance) + 3% (health insurance) + 1% (unemployment insurance) = ~21.5% of gross salary; employee pays roughly 8% (social) + 1.5% (health) + 1% (unemployment) = ~10.5%, all subject to a statutory monthly salary cap for contribution calculation purposes.
Foreign employees have been subject to mandatory social insurance contributions since 2018 (compulsory participation phased in over social/health/unemployment insurance components), a change many longer-tenured expats and their employers still misunderstand.
Benefits include: sick leave pay, maternity/paternity leave pay, work injury/occupational disease compensation, retirement pension (for those meeting minimum contribution years and retirement age), and survivor benefits.
Foreign employees who leave Vietnam permanently (or whose work permit/residency ends without renewal) are generally entitled to claim a one-time lump-sum social insurance payout rather than waiting to draw a small pension from abroad — a valuable but under-utilized benefit.
Unemployment insurance provides limited unemployment benefits and job-search support for eligible contributors who lose employment involuntarily and meet minimum contribution period requirements.
Employers who fail to register employees for social insurance or under-report salary for contribution purposes face penalties and back-payment liability, plus reputational/compliance risk in audits.
Steps
Register new employees promptly — Register both Vietnamese and eligible foreign employees for social, health, and unemployment insurance within the statutory window after their labor contract begins.
Calculate contributions correctly against the salary cap — Apply contribution rates against the employee's declared salary up to the statutory monthly cap, not the full uncapped salary for high earners.
Remit contributions monthly — Pay both employer and withheld employee contributions to VSS monthly, alongside other payroll filings.
Advise foreign employees on their lump-sum claim option — When a foreign employee's Vietnam employment ends permanently, help them understand and file for the one-time social insurance lump-sum payout rather than leaving contributions unclaimed.
Maintain accurate contribution records — Keep clean records of contribution history, since this underpins both benefit claims (sick leave, maternity, injury) and any future audit defense.
Costs
Employer contribution: ~21.5% of gross salary (capped)
Employee contribution: ~10.5% of gross salary (capped)
Timelines
Registration after employment start: Typically within 30 days
Lump-sum payout claim processing (departing foreign employees): Typically several weeks to a few months after application
Assuming foreign employees are exempt from mandatory social insurance — coverage has applied to foreign workers since 2018 reforms.
Under-declaring salary for contribution purposes to reduce employer costs, which creates penalty and back-payment exposure on audit.
Foreign employees leaving Vietnam without claiming their one-time social insurance lump-sum payout, effectively forfeiting contributed funds.
Missing the registration window for new employees, delaying their coverage and complicating any near-term benefit claims (e.g., early maternity leave).
