Social Security for Domestic Workers in Thailand: Who Pays

What the Thai Cabinet Approved on 25 August 2026

The Cabinet approved a draft Royal Decree amending the Royal Decree Prescribing Businesses and Employees Excluded from the Social Security Act B.E. 2560 (2017). In short, that 2017 instrument explains why certain workers currently sit outside the system. Indeed, the Social Security Act B.E. 2533 (1990) casts a deliberately wide net, and the Royal Decree then carves specific groups back out. Consequently, the Ministry of Labour does not need to amend the Act itself. It only needs to shorten the exclusion list.

Two features of the approval deserve attention. First, the Council of State lengthened the transition period from 60 days to 180 days after publication in the Government Gazette. Employers would therefore gain a six-month runway rather than a two-month scramble. Second, the Ministry of Labour projects roughly 1,050,000 additional insured persons by 2030. That figure signals the scale of the population the Social Security Office expects to absorb.

Who the Draft Royal Decree Brings Into Section 33

The draft removes three exclusions. Importantly, each one carries a carve-out that survives, and those carve-outs matter more than the headline.

Why Social Security for Domestic Workers Is Different

The first and third groups are businesses, however small. The second group is a household, and that distinction drives the practical difficulty. A company already runs payroll, holds an employer account and files monthly returns. A family does not. Under the draft, an individual who employs a live-in helper would become a registered employer under section 33. That role brings a contribution account, statutory filing deadlines and personal exposure for arrears.

Foreign residents feel this shift acutely. Many expatriate households in Bangkok, Phuket and Chiang Mai engage a helper on an informal, cash basis with no written terms. For years, that arrangement survived because nobody was watching. Once registration becomes compulsory, the arrangement acquires a paper trail, and the paper trail is what changes the risk profile.

What the Contributions Would Cost an Employer

Section 33 contributions run at 5% of wages from each side, calculated against a statutory band. Since 1 January 2026 the band has run from a floor of THB 1,650 to a ceiling of THB 17,500 per month. Moreover, the ceiling rises to THB 20,000 for 2029 to 2031, and to THB 23,000 from 2032. We examined that phased increase in our analysis of Thailand’s social security pension reform.

Migrant Staff: Nationality Does Not Decide Coverage

The Social Security Act does not condition registration on nationality. The Cabinet briefing confirmed that coverage would reach Thai and non-Thai employees alike. The worker must simply hold valid identity documents and a work permit. Notably, that includes migrant workers admitted under special permission to work in the Kingdom. Employers of Myanmar, Lao and Cambodian household staff therefore cannot treat this as a Thai-national issue.

Furthermore, a second point follows. Registration compels the employer to declare the job and the wage. Consequently, any mismatch between the permit and the work performed becomes visible to the authorities. Where a permit describes one occupation and the worker performs another, the immigration and labour problem precedes the contribution problem. Our guide to work permits for Myanmar nationals sets out how those categories operate in practice.

Employer Duties Under Social Security for Domestic Workers

If the decree takes effect unchanged, the duties already familiar to Thai companies would transfer wholesale to newly covered employers.

1. Register and file employee details. Section 34 requires particulars to reach the Social Security Office within 30 days of the employee becoming an insured person.
2. Deduct the employee share at source. The employer withholds 5% from wages each pay period rather than recovering it later.
3. Remit both shares by the fifteenth. Section 47 sets the deadline at the fifteenth day of the month following deduction, together with the prescribed remittance form.
4. Keep wage records. The declared wage must match actual payments, because the same figure drives contributions, benefits and any later dispute.
5. Report changes promptly. New hires, departures and wage adjustments each require a filing, and the Social Security Office treats silence as a discrepancy.

Late or short remittance carries a 2% monthly surcharge under section 49, running from the day after the deadline. Helpfully, the Act caps that surcharge at the amount of the outstanding contributions, so arrears cannot compound indefinitely. Nevertheless, an employer who never registers at all faces the arrears, the surcharge and the offence together.

The Quiet Consequence: Labour Protection Act Exposure

Households often assume that Thai labour law leaves domestic work alone. It does not. Ministerial Regulation (No. 14) B.E. 2555 already extends much of the Labour Protection Act B.E. 2541 to domestic work. Entitlements include one weekly rest day, the traditional annual holidays, six days of annual leave after a year of service and up to 30 days of paid sick leave. Minimum wage and maximum daily hours sit outside that regulation, but the leave entitlements do not.

Enforcement has been thin for one simple reason: households are invisible to the labour inspectorate. Compulsory registration would nevertheless end that invisibility. An employer account, a declared wage and a monthly filing together document the relationship, its duration and its pay rate. A helper claiming unpaid holiday pay or severance would reach the Labour Court with that record in hand. Employers should read this alongside the expanding criminal liability attaching to labour breaches in Thailand.

Social Security for Domestic Workers: Using the 180-Day Runway

Because the transition period begins only on Gazette publication, employers have time to prepare rather than react. We recommend five practical steps during that window.

1. Map the affected staff. List every person paid directly by an individual or by a seasonal agricultural operation. Then identify the draft category.
2. Fix the wage figure honestly. A declared wage that diverges from actual payments creates exposure under the social security regime and the Revenue Code alike.
3. Audit permits and identity documents. Migrant staff must hold documentation that matches the work performed before registration makes the position public.
4. Budget the employer share. Add roughly THB 9,000 to THB 10,500 per full-time employee each year. Revisit the figure when the ceiling rises in 2029.
5. Put the terms in writing. A short written engagement recording wage, rest days, leave and duties protects both sides once the arrangement becomes public.

For the underlying instruments, employers can consult the Social Security Office. The International Labour Organization translation of the domestic work regulation is also useful.

Frequently Asked Questions on Social Security for Domestic Workers

Where This Leaves Employers

Ultimately, this reform reframes a familiar arrangement. For decades, employing household help sat in a grey zone where the law existed but the record did not. The draft decree closes that gap, and it does so for a population of roughly a million workers. Businesses with seasonal agricultural labour simply face a budgeting exercise. Households face something less familiar: becoming an employer of record for the first time. Prudent employers will use the runway rather than wait for the Gazette.
