Probation in Vietnam: Guide for Employers on Salary, Social Insurance, and Tax Compliance – Updated 2026

For employers building or expanding a workforce in Vietnam, probation is far more than a procedural formality — it’s a legally regulated phase that shapes cost structure, compliance posture, and the early employment relationship itself. Yet many businesses still treat probation as an afterthought, only to face administrative penalties or unexpected payroll liabilities once contracts mature. This guide unpacks the four pillars every employer must master: probation duration, probationary salary, contract structure, and the resulting obligations on social insurance and personal income tax. Each section is designed to help HR leaders, business owners, and payroll teams move from compliance awareness to confident execution.

Structuring the Probation Period: Flexibility Within Strict Legal Limits

Vietnamese labor law strikes a deliberate balance between employer flexibility and worker protection. The probation period is freely negotiable — but only within the boundaries the law has set, and only once per specific job role.

The maximum probation periods are tiered by job complexity:

Up to 180 days for enterprise managers governed by the Law on Enterprises and the Law on Management and Use of State Capital in Production and Business.
Up to 60 days for positions requiring college-level qualifications or higher.
Up to 30 days for roles requiring intermediate qualifications, technical workers, or office staff.
Up to 6 working days for all other positions.

One critical rule that catches many employers off guard: probation can only be applied once per specific job. If an employee fails probation and is later considered for the same role, no second probation is permitted. However, if the role substantively changes — different scope, different responsibilities, different professional level — a fresh probation period becomes legally defensible.

Probationary Salary: The 85% Rule

At its simplest, the rule is straightforward: probationary salary must be at least 85% of the official salary for the position.

The 85% threshold is a legal minimum, not a recommended figure. Employers are entirely free to pay 100% of the official salary during probation, and many forward-thinking businesses do exactly that to attract competitive talent and signal trust from day one.

The official salary used to calculate the 85% must itself meet or exceed the regional minimum wage. From January 1, 2026, the regional minimum wages are:

Region I: VND 5,310,000/month
Region II: VND 4,730,000/month
Region III: VND 4,140,000/month
Region IV: VND 3,700,000/month

Choosing the Right Probation Contract Structure

Vietnamese law offers employers two valid ways to structure probation. The choice is not just administrative — it directly shapes social insurance costs, tax treatment, and how attractive the role appears to candidates.

Option 1: Standalone Probation Contract
A separate, short-term agreement used only for the evaluation period. If the employee passes, a formal labor contract is signed afterward. This approach keeps early-stage obligations light.

Option 2: Probation Embedded in the Labor Contract
Probation terms are written directly into the main labor contract from the start. There is no separate document; probation simply becomes the first phase of employment.

Universal Rules That Apply to Both Options

Three rules are the same regardless of structure:

No probation is allowed on contracts shorter than one month.
Either party can end the relationship during probation without notice or compensation.
The employer must formally notify the employee of the result at the end of probation. Under Option 1, a formal labor contract must be signed immediately if the employee succeeds.

Social Insurance Obligations

The biggest difference between the two options lies in compulsory social insurance (social insurance, health insurance, and unemployment insurance).

Standalone Probation Contract

No contributions required for any of the three schemes.
The employer saves costs during probation.
The employee earns no insurance accrual for that period.

Probation Embedded in the Labor Contract

Insurance obligations begin on day one and depend on contract length:

1 month or longer: Social insurance + health insurance required. From 1 January 2026, unemployment insurance is also required.
3 months or longer: Full coverage — social insurance, health insurance, and unemployment insurance.

The 2026 change is significant: unemployment insurance now applies to any labor contract of one month or more, closing the previous loophole that allowed shorter contracts to avoid it.

Personal Income Tax Treatment

Tax rules also follow the contract structure.

Standalone Probation Contract (or Embedded Contract Under 3 Months)

Treated as casual income.
No withholding if payment is under VND 5 million per occurrence (2026 updated)
10% flat withholding applies at VND 5 million or above (2026 Updated)
The 10% can be waived if the employee submits Form 08/CK-TNCN confirming this is their only income and total annual earnings stay below the taxable threshold.

Embedded Probation Contract of 3 Months or More

Treated as regular salary income.
Taxed under the progressive personal income tax schedule.
The employee receives the standard monthly deductions (VND 15.5 million personal deduction + VND 6.2 million per dependent) and can deduct compulsory insurance contributions.
Most probationary salaries fall below the taxable threshold after deductions, so little or no tax is usually payable.
