Since 7 December 2025, the Labour Protection Act (No. 9) B.E. 2568 has raised maternity leave from 98 to 120 days, increased the days the employer must pay from 45 to 60, and created two rights that did not exist before: 15 days of leave at full pay for the spouse of someone giving birth, and a further 15 days of child-care leave at half pay.

Most material online still carries the old figures. What makes this hard to work out yourself is that the money does not come from one place: the employer pays under the labour law, and social security pays two further amounts — a lump sum for the birth and a work-stoppage allowance — each with its own conditions and ceiling. This page brings all of them together.

How it works

Part 1 — wages from the employer. The employer must pay wages equal to working days throughout the leave, but for no more than 60 days, under the amended Section 59. The remaining days are unpaid by the employer, but the leave can still be taken up to 120 days without counting as absence.

Part 2 — the lump-sum childbirth payment. 15,000 baht per birth as a flat medical benefit, with no limit on the number of claims. An insured man may claim it for his wife, but where both spouses are insured only one side may claim.

Part 3 — the work-stoppage allowance. For insured women only: 50% of the average wage for 90 days, limited to two claims, so a third or later birth does not receive it. The average wage is based on the contribution wage, which is capped at 17,500 baht a month — at that ceiling the allowance reaches 26,250 baht.

The social security condition. At least 5 monthly contributions within the 15 months before the month of birth, not necessarily consecutive. Falling short means neither social security payment, though leave and employer-paid wages are unaffected because they come from a different law.

The spouse’s right. Up to 15 days per pregnancy at full pay under Section 59/2, to be taken within 90 days of the birth.

Counting the days. Maternity leave is counted in calendar days, not working days. Holidays within the period count towards it, and days taken for prenatal check-ups come out of the same 120-day allowance.

Frequently asked questions

Are all 120 days paid?

Not by the employer. The employer pays for up to 60 days; the other 60 are unpaid by them. An insured woman receives the social security work-stoppage allowance to cover part of the rest — 50% of the average wage for 90 days.

How much leave does the father get, and is it paid?

Up to 15 days per pregnancy, at full pay throughout. This is a new right under the law that took effect on 7 December 2025, and it must be used within 90 days of the birth.

I earn 40,000 baht — what allowance will I get?

The same as someone on 17,500 baht: 26,250 baht, because the base is capped at the contribution ceiling. Employer-paid wages for the first 60 days are calculated on your actual wage, with no ceiling.

Is a third child covered by social security?

The 15,000 baht lump sum still applies, as it has no limit on claims. The work-stoppage allowance does not, because it is limited to two claims.

Can anyone take the extra 15 days of child-care leave?

No. It applies only where the child is ill with a risk of complications, has an abnormality, or has a disability, and a medical certificate from a modern-medicine practitioner is required. Those days are paid at half the wage.

Does a miscarriage count as maternity leave?

No. A miscarriage — a pregnancy ending before 28 weeks — falls under sick leave in Section 32 instead. Where the child is born and dies later, the maternity leave entitlement and wages are unaffected.
