Updated September 2026. Whether foreigners on short-term contracts pay Social Insurance in Vietnam is decided by one line in the law, and it is shorter than most people expect: a fixed-term labor contract of 12 months or more with an employer in Vietnam. Below that line there is no compulsory enrolment, no contribution, and nothing to claim when you leave. This guide from terra on Social Insurance for short-term contracts sets out the test, the three exclusions in Decree 158/2025/ND-CP, where directors and managers sit, and how to check your own position without asking HR.
| Your situation | Compulsory Social Insurance? |
|---|---|
| Labor contract of 12 months or more with a Vietnamese employer | Yes, unless an exclusion below applies |
| Contract of 3, 6 or 11 months | No |
| Intra-company transferee | No |
| Already at retirement age when the contract was signed | No |
| Covered by an international treaty that says otherwise | Depends on the treaty |
| Director or manager with no labor contract | No, because the test is the contract |
Do foreigners on short-term contracts pay Social Insurance?
No. A foreign national working in Vietnam joins the compulsory scheme only under a fixed-term labor contract of 12 months or more, under Article 2 of the Law on Social Insurance 2024 and Article 3, Clause 1 of Decree 158/2025/ND-CP, both in force from 1 July 2025. A contract of eleven months does not enrol you, and eleven months of work does not build an entitlement.
This is a boundary, not a sliding scale, and that is the part people get wrong. There is no partial coverage for a nine month posting and no pro-rata credit. Two consecutive six month contracts are not a twelve month contract either, although a genuine extension that takes the term past twelve months does change the position going forward.
The stance worth stating plainly: finding this out on the way out is expensive, and it happens constantly. Every month a short-term foreign employee spends assuming a payout exists at the end is a month of financial planning built on nothing. Check it in the first week, not the last.
Social Insurance for short-term contracts: the twelve month test
Read the contract, not the visa and not the assignment letter. The test looks at the labor contract signed with an employer in Vietnam, its type and its term. A work permit is a separate document with a separate purpose, and holding one does not by itself put you in the scheme.
Three practical traps sit inside that sentence. First, who the contract is with: if you remain employed by the overseas parent and are only assigned here, there may be no Vietnamese labor contract at all. Second, the term as written: contracts sometimes say twelve months but start with a probation period documented separately, and what matters is the labor contract itself. Third, the number of employers: a foreign employee with two Vietnamese contracts is treated under the rules for that situation rather than by adding the terms together.
If you are covered, what you pay and what the salary cap does to it is a separate subject, covered in the guide to Social Insurance contribution rates for foreigners.
Who the law leaves out
Three exclusions apply even when the twelve month test is met, and each one is a complete carve-out rather than a reduction.
Intra-company transferees
A foreign employee moved within the same corporate group under the rules on foreign workers in Vietnam is outside the compulsory scheme. The rationale is that the employment relationship stays with the sending entity. In practice this is the largest excluded group among senior expatriates, and many of them believe they are contributing because a deduction appears on a payslip issued elsewhere.
If you were transferred rather than hired, check your status before you assume anything about a claim. The exclusion applies to your position, not to your job title, and it is recorded in how your work permit was issued.
Already at retirement age when the contract was signed
If you had reached Vietnamese retirement age at the moment the labor contract was signed, you are excluded. The threshold moves every year under Article 169 of the Labor Code 2019: from 1 January 2026 it is 61 years and 6 months for men and 57 years for women, rising by three months a year for men and four months a year for women until it reaches 62 and 60 respectively.
Note the timing test, because it is unusual. What matters is your age when the contract was signed, not your age now. Someone who signed at 60 and turned 62 during the term stays inside the scheme, while someone who signed after reaching the threshold was never in it.
Covered by an international treaty
Where a treaty Vietnam is party to provides otherwise, the treaty governs. As of September 2026 the one in force is the bilateral agreement with Korea, applied since 1 January 2024, which lets a seconded worker stay in the home country’s scheme instead of contributing twice. That agreement has its own consequences for anyone deciding whether to take a one-time payment, set out in the guide to the Vietnam Korea Social Insurance agreement.
Are directors and managers covered?
Only if they hold a labor contract of 12 months or more. For a foreign national the test is the contract, not the role, so a general director who signed a two year labor contract is inside the scheme on the same terms as anyone else, and a chairman appointed by resolution with no labor contract is outside it.
This produces results that feel inconsistent and are not. Two people can run the same company, draw comparable money, and sit on opposite sides of the line because one was hired and the other was appointed. The paperwork is the substance here, which is why the question to ask is what you signed rather than what you do.
Where it gets genuinely uncertain is a foreign manager who is both appointed and paid under an arrangement that is not a labor contract. That is a position worth having reviewed rather than assumed, because the answer drives payroll, Personal Income Tax treatment and the exit position together. Companies that guess here tend to guess in the direction that is cheaper this year.
The line that decides everything A fixed-term labor contract of twelve months or more with an employer in Vietnam, and none of the three exclusions Everything else follows from that one sentence: whether you contribute, whether a payout exists when you leave, and whether the months you spent here count for anything at all. Article 2 of the Law on Social Insurance 2024 and Article 3, Clause 1 of Decree 158/2025/ND-CP, in force since 1 July 2025. |
What it means if you were never enrolled
There is nothing to claim, and no procedure will create something. The one-time payment is calculated from contributions actually paid into the retirement and survivorship fund under your Social Insurance number. No contributions means no record, and no amount of paperwork at the office changes that.
Two consolations, and one of them is real. The real one: the money that would have been deducted stayed in your pay, and the employer contribution was never a cost to you in the first place. The illusory one is the idea that a short posting can be retroactively insured by paying in later. Voluntary participation is a separate scheme with different rules, and it is not a route to backfill a period you were never enrolled for.
The boundary this article does not cross: being outside compulsory Social Insurance says nothing about your health insurance, your Personal Income Tax position or your work permit obligations, which run on their own rules. It also says nothing about periods with a different employer. If you had an earlier Vietnamese contract of twelve months or more, that period stands on its own and may still be claimable when you leave.
What it costs an employer to get this wrong
An enrolment decision made wrongly at hiring does not stay small. It compounds month by month and surfaces at the worst moment, either during an inspection or when an employee asks for their book on the way out. The two directions of error cost differently.
| The error | What follows | When it surfaces |
|---|---|---|
| Should have enrolled, did not | Arrears for the whole period, plus 0.03% per day on the outstanding amount (Article 40). Deliberate avoidance can bring administrative penalties and, in serious cases, criminal liability (Article 41) | At inspection, or when the employee checks their own record |
| Enrolled someone excluded, such as a transferee | Contributions paid without an obligation, and an adjustment to unwind rather than a payout to collect | Usually when the employee tries to claim and the entitlement does not match the record |
| Enrolled late, after the contract started | A gap in the middle of the record that has to be explained and corrected before any claim | At the exit, when the months do not add up |
The asymmetry is worth naming. Under-enrolment is a liability that grows daily and is enforced against the company. Over-enrolment is mostly a reconciliation problem, and it is the employee who discovers it. Neither is cheap, but only one of them accrues interest, which is why the conservative reading of a borderline case is usually the right one.
How to check your own position in an afternoon
Three checks, in this order, and none of them requires HR to agree with you.
- Read the term and the parties on your labor contract: Twelve months or more, signed with a Vietnamese entity. If either fails, stop here, you are outside the scheme.
- Check how your work permit was issued: The intra-company transfer route is recorded there, and it is the exclusion people most often discover late.
- Look yourself up in the Social Insurance system: Either you have a Social Insurance number with contribution months against it or you do not. This is the answer that settles the argument, because it shows what was actually paid rather than what anyone intended.
If step three shows contributions, you are in the scheme and the exit questions apply to you: what the payout is worth, what documents you need, and when to start. The guide to one-time Social Insurance for foreign employees covers those. If step three shows nothing and you believed you were enrolled, the gap is worth investigating rather than accepting, because the other explanation is that an employer deducted and did not pay.
What to do next
Settle the question now rather than at your exit interview. Whether foreigners on short-term contracts pay Social Insurance in Vietnam has a definite answer for your own file, and it takes an afternoon to find. Employers should run the same check across their foreign headcount, because an enrolment decision made wrongly at hiring compounds quietly for years and surfaces during an inspection or on the way out.
For the wider set of rules that changed for foreign employees this year, see the Social Insurance changes for foreign employees in Vietnam.
Not sure which side of the line you are on terra checks enrolment status against the record, not against the intention For an individual, that means telling you whether contributions exist and what they are worth. For an employer, it means reviewing the foreign headcount before an inspection does. If contributions exist and you are leaving, terra can run the claim: published fees are VND 10 million at signing plus 15% of the amount withdrawn, charged only after the money reaches you, both before VAT.
