Overtime and holiday pay in Thailand

The multiplier is not the hard part — working out which one applies is. It depends on how the wage is expressed and on which kind of holiday was worked, and getting it wrong is the most common payroll error in Thailand.

Work out the pay

Enter how the employee is paid and the hours worked. The calculator picks the correct statutory limb for you and shows which one it used.

This is not cosmetic. It decides how the hourly rate is derived and, on a weekly holiday, which multiplier applies.

Section 68 converts this to an hourly rate by dividing by 30 × the normal daily hours. The 30 is fixed by statute, not by the days in the month.

Used to derive the hourly rate. Normal hours cannot exceed 8 a day, or 7 for work hazardous to health.

Section 23 sets a lower ceiling for hazardous work, so overtime starts an hour earlier in the day.

The ordinary overtime and holiday rules apply in full.

This matters as much as the wage basis. Weekly holidays behave differently from traditional holidays and annual leave.

Overtime is prohibited unless the employee consents in advance and on each occasion — a blanket clause in the contract does not satisfy section 24. Consent is not required for genuinely continuous work that would be damaged by stopping, or for emergency work, but the pay is owed either way.

The statutory rates

When the work is doneRate
Overtime on a working day — section 611.5×
Work on a holiday, employee entitled to holiday wages — section 62(1)1× additional
Work on a holiday, employee not entitled to holiday wages — section 62(2)2× flat
Overtime on a holiday — section 63

Each rate multiplies the hourly wage rate of a working day, or the per-unit rate for piece work. All four are floors — a contract or work rule may pay more, never less. Sections 61, 62, 63 and 68 have never been amended and stand as enacted in B.E. 2541.

Why two employees can be paid differently for the same holiday shift

Section 62 has two limbs. An employee who is entitled to wages on the holiday receives one additional time the hourly rate, because the wage covering that day is already being paid. An employee who is not entitled receives a flat two times, and nothing else for that day. Over a full normal working day the two land on the same economic total — which is why paying a salaried employee two times on top of salary is the classic error, and overpays by half again. They stop coinciding on a part day, because the salaried employee keeps the whole day's wage while the other is paid only for hours worked.

Section 56 is the switch. It requires a working day's wage to be paid for the weekly holiday, for traditional holidays and for annual leave — but the weekly holiday carries an exception for employees paid daily, hourly or by piece. Traditional holidays and annual leave carry no such exception.

So a daily-paid employee working a weekly holiday falls into the second limb and is owed two times. The same employee working a traditional holiday is entitled to wages for that day under section 56(2) and therefore falls into the first limb, owed one additional time. A monthly-salaried employee is entitled on all three and is always in the first limb.

How the hourly rate is derived

For a monthly-paid employee, section 68 divides the monthly wage by 30 multiplied by the average number of working hours in a working day. The 30 is a fixed statutory number, not the number of days in the month. Section 68 is written for computing overtime and holiday pay, and it is not authority for converting a monthly salary into a daily severance rate — severance is measured on a different footing altogether, in days of the last wage rate under section 118.

For a daily-paid or hourly-paid employee the Act supplies no divisor. An hourly wage is already the rate the sections refer to. A daily wage has to be divided by the normal daily hours, which follows from the section 5 definition of the working-day wage as the wage for full normal working time — a construction of the Act rather than a figure it states outright. This calculator flags that on the face of the result rather than presenting it as section 68.

Who is outside the overtime rules

Section 65 removes the entitlement to overtime pay and holiday overtime pay from nine categories of employee. It is narrower than it is usually treated as being, and it does not touch ordinary holiday pay except in one case.

  • Section 65(1) — an employee with authority to act for the employer on hiring, granting reward, or termination. Seniority, job title and salary are irrelevant; the test is the actual authority. This is the only category that also loses holiday pay, and only because section 66 says so, and only unless the employer agrees to pay it.
  • Section 65(2) — peddling or canvassing sales on commission paid by the employer. No overtime pay, but holiday pay under section 62 is preserved in full.
  • Sections 65(3) to (9) — rail work, work away from the employer's premises, watching over premises other than as a normal duty, emergency work, and the other listed categories. These employees receive no overtime pay as such, but are entitled to compensating remuneration equal to one time the hourly working-day rate for the hours worked, and keep their holiday pay.

One category has moved, and it matters. The Ministerial Regulation that placed watching over premises as a normal working duty inside section 65(9) was repealed with effect from around 25 April 2026, so a security guard whose ordinary job is guarding is no longer excluded on that basis — zero is not an available answer for them. A separate Ministerial Regulation of B.E. 2568 sets 1.25× overtime and 2.5× holiday overtime for certain service work, and whether a normal-duty guard falls inside that description is an unsettled scope question. This calculator does not resolve it: select “no category” and it applies the full section 61 and 63 rates, which is the higher of the two possible answers.

Limits the calculator does not enforce for you

  • Normal working hours may not exceed eight a day and forty-eight a week, or seven and forty-two for work hazardous to health or safety. Hours beyond those are overtime.
  • Overtime and holiday work together may not exceed thirty-six hours a week. Section 26 states no number itself — it delegates entirely to a Ministerial Regulation, which is why the figure should be cited to the regulation and not to the section.
  • A rest period of at least one hour is required after no more than five consecutive hours of work, and at least twenty minutes before overtime that runs on from normal hours for two hours or more.
  • Overtime requires the employee's prior consent on each occasion. Whether a given task is genuinely continuous or an emergency, which removes the consent requirement, is a question of fact this tool cannot decide.

Which limb applies

Section 62(1) — one additional time

The employee is entitled to wages for this holiday, so the wage for the day is already owed and the holiday-work payment sits on top of it.

Normal working hours on these facts: 8 a day, 48 a week. Anything beyond that is overtime.

This tool sets out provisions of Thai statute and computes from them. It is not legal advice, does not create a lawyer–client relationship, and does not account for your employment contract, work rules or collective agreement, any of which may provide more than the statutory floor. Whether a particular employee falls within a section 65 category, and whether particular work is continuous or an emergency, are questions of fact it cannot decide. Take advice from a licensed Thai lawyer before relying on these figures.

Payroll that gets the limb right every time

Most Thai overtime disputes are not about the multiplier — they are about which limb applied, whether the consent was valid, and whether the employee was inside section 65 at all. Our payroll team runs these rules across mixed workforces of salaried, daily and piece-rate staff, and documents the basis for each.
