Can Employers Deduct Salary for Late Employees? Clear Answers and Legal Guidelines under Thai Labour Law 2025

“Another late employee again. If I deduct their salary, I’m worried it’s illegal. If I calculate it manually, I risk making mistakes…” — this is one of the most common headaches for HR managers and SME business owners.

This article explains clearly what the Labour Law says about lateness, how to handle it properly, and introduces a “tool” that can make this issue much easier to manage.

Many companies mistakenly believe that deducting salary as a punishment for lateness is allowed. In fact, under Section 76 of the Labour Protection Act, salary deductions as a penalty are illegal.

What employers can do is apply the principle of “No Work, No Pay” — not paying wages for the actual time employees fail to work. For example, if someone arrives 30 minutes late, the employer may reduce payment for that portion of time, but it must be calculated correctly and transparently.

For more details, employers can check with the Department of Labour Protection and Welfare, which is the main authority interpreting Thai labour law.

How to Apply “No Work, No Pay” Correctly

Manual Calculation Method

Example: Employee earns 30,000 THB/month, works 8 hours/day.

• Daily wage = 30,000 ÷ 30 = 1,000 THB
• Hourly wage = 1,000 ÷ 8 = 125 THB
• 30 minutes late = 125 ÷ 2 = 62.5 THB
  

This looks simple, but with many employees arriving late at different times, calculating manually (or using Excel) becomes time-consuming, complicated, and prone to human error.

Modern Method: Using Payroll Software

This is where payroll software turns a painful task into an automated process:

• Accuracy: Integrated with time attendance systems, it calculates wage deductions down to the minute.
• Speed: At month-end, the system consolidates all calculations instantly, saving HR countless hours.
• Error Reduction: Minimises disputes by eliminating miscalculations.
• Transparency: A good payroll system can show “unpaid wage for absent time” as a separate line on payslips, so employees clearly see deductions.

Transparent payroll communication is crucial. A good payroll system will automatically display “unpaid wage for absent time” as a separate line in payslips. Employees can see it clearly, and employers have strong documentation to rely on in case of disputes.

Ultimately, salary deduction is only treating the symptom. With more time freed up (thanks to automation), HR can focus on conversations with employees, tackling root causes of lateness, and fostering a healthier workplace culture.

• Deducting salary as punishment is illegal under Section 76 of the Labour Protection Act.
• What is allowed is “No Work, No Pay” — withholding wages for the precise time not worked.
• Manual calculation is possible, but slow, error-prone, and risky.
• Payroll software is the most accurate, transparent, and professional solution.
