In the bustling manufacturing hubs of Bac Ninh and the 24/7 service centers of Ho Chi Minh City, the lights never go out. But as we move through 2026, those shift work lights are bringing a new level of inspection from the Department of Labor, Invalids and Social Affairs (DOLISA).
Under the 2025 Employment Law updates, the margin for error in payroll has vanished. If your business relies on rotating shifts, you aren’t just managing schedules, you are managing a high-stakes math problem.
The 40-Hour Monthly Ceiling
The most immediate trap for Vietnamese SMEs in 2026 is the strict 40-hour monthly overtime limit. While some specific industries can apply for the 300-hour annual cap, the monthly “speed limit” remains 40 hours for most. Crossing this line doesn’t just result in a fine; it flags your company for a comprehensive labor audit.
The “Night Shift Overtime” Math
Many HR managers mistakenly calculate night shift overtime as a flat rate. In reality, Vietnam’s Labor Code and Decree 145 require a “layered” approach that confuses even the most seasoned accountants.
If a worker is on a rotating shift and their overtime bleeds into the night (10:00 PM – 6:00 AM), the calculation looks like this:
- Standard Overtime Rate: 150% (Weekday).
- Night Shift Extra: +30% of the actual hourly wage.
- The “Top-Up”: An additional 20% calculated on top of the daytime overtime rate.
The 2026 PIT Bonus: Here is some good news for your staff, as of January 1, 2026, all overtime and night shift pay is now 100% exempt from Personal Income Tax (PIT). This is a major shift from previous years where only the “extra” portion was exempt.
2026 Vietnam Overtime Rate Reference Table
Use this table to ensure your payroll is configured correctly for current DOLISA standards.
| Work Scenario | Time Period | Multiplier (of Hourly Wage) |
| Weekday Daytime | 6:00 AM – 10:00 PM | 150% |
| Weekday Night (No prior OT) | 10:00 PM – 6:00 AM | 130% |
| Weekday Night (Overtime) | 10:00 PM – 6:00 AM | 210%* |
| Sunday/Rest Day Daytime | 6:00 AM – 10:00 PM | 200% |
| Sunday/Rest Day Night (OT) | 10:00 PM – 6:00 AM | 270% |
| Public Holiday/Tet Daytime | 6:00 AM – 10:00 PM | 300% |
| Public Holiday/Tet Night (OT) | 10:00 PM – 6:00 AM | 390% |
*Formula: 150% (OT) + 30% (Night) + [20% x 150% (Top-up)] = 210% (source)
Why Manual Tracking is a 2026 Liability
If you are still using Excel to track these rotating patterns, you are essentially “auditing yourself” into a corner.
- The Tracking Gap: Manual logs often miss the 10:00 PM transition, leading to underpayment.
- The Consent Requirement: Under current law, you must have explicit employee consent for overtime. If you can’t produce a digital or paper trail of that consent for every shift, the hours worked are considered illegal.
- The Reference Level Change: With the 2026 Reference Level at 2,340,000 VND, the caps for Social Insurance are higher, meaning every overtime hour needs to be precisely separated from “base pay” to avoid over-contributing to insurance funds.

The Tet holidays and regional minimum wage hikes of 2026 are already here. Don’t let a “Shift Work Trap” hold back your growth in Vietnam.
Don’t Leave Your Compliance to Chance
In the fast-evolving landscape of Vietnam’s 2026 Labor Market, staying “compliant enough” is no longer an good enough. Between shifting Regional Minimum Wages and the intricate math of night-shift premiums, the risk of manual error is a ticking time bomb for your payroll.
But HR is about more than just dodging fines, it’s about building a culture of trust and transparency that keeps your best talent from walking out the door. When your shift work calculations are precise and your employees can verify their earnings instantly, you aren’t just running a business; you’re leading a professional, world-class organization.
