JST Group
The Thailand Specialist Who Knows the Ministry by Name
JST Group occupies a distinct niche in the Thai employment services market: rather than positioning itself as a global platform with a Thailand module, it operates as a Southeast Asia specialist with genuine operational depth in Bangkok. That distinction matters more in Thailand than in most markets, because Thai employment compliance is administered through a patchwork of agencies including the Department of Employment, the Social Security Office, the Revenue Department and, for foreign hires, the Board of Investment or One Stop Service Centre. Providers who lack local standing tend to hit friction at exactly these touchpoints, and JST's team has the local registration footprint and language capability to navigate them directly rather than through subcontracted intermediaries.
The firm's target market skews toward small and mid-sized international businesses testing the Thai market, professional services firms placing consultants on client sites, and companies in manufacturing, logistics and trading that need staff in Thailand but do not yet warrant a Thai limited company. JST's broader service line, which spans company incorporation, accounting, tax filing and corporate secretarial work, means clients can start on an EOR arrangement and later transition to their own entity without changing advisers, a continuity that larger platform vendors rarely offer.
Where JST is strongest is in the messy edge cases: work permit and Non-B visa sponsorship, the quota rules that tie foreign hires to registered Thai capital and local headcount ratios, severance calculations under the Labour Protection Act, and the practicalities of Provident Fund enrolment. Buyers evaluating JST should expect a relationship-led, consultative engagement model rather than a self-service dashboard, and should scope service levels and response times explicitly during contracting.
Key Features:
- Work permit and Non-Immigrant B visa sponsorship handled in-house
- Thai Social Security Office registration and monthly contribution filings
- Withholding tax and PND filings aligned to Revenue Department deadlines
- Labour Protection Act compliant contracts in Thai and English
- Pathway from EOR to client-owned Thai entity incorporation
- Payroll processing with Thai bank disbursement and payslip issuance
Why I Picked JST Group:
I included JST Group because they solve the problem most global EOR platforms quietly outsource in Thailand: foreign work permits and the BOI or quota mechanics behind them. Their combined EOR and corporate services offering also gives clients a credible exit path once headcount justifies a local entity. For companies hiring expatriates into Bangkok, that in-house immigration capability is the deciding factor.
