You set up a Thai company. You got your Non-B visa. Now you need to hire — and you're discovering that none of your US or EU hiring instincts translate. The salary data is opaque, LinkedIn is half-empty, every recruiter quotes a different fee, and there's a labor law from 1998 (the Labor Protection Act B.E. 2541) that quietly governs everything you sign.
The four hardest parts of a first Thai hire for foreign founders are: calibrating salary against a market where public data is thin, navigating the 4:1 Thai-to-foreign work permit ratio, writing a contract that survives the Labor Protection Act, and registering with the Social Security Office (SSO) inside the 30-day window. Get those four right and you've cleared the operational tax that crushes most first-time hires.
2026 Thai Minimum Wage by Province
The National Wage Committee under the Ministry of Labour sets daily minimum wages by province. As of 2026, the range is THB 337—400/day.
| Tier | Daily Wage (THB) | Provinces / Sectors |
|---|---|---|
| Top | 400 | Bangkok, Phuket, Chonburi, Rayong, Chachoengsao, Koh Samui; nationwide hotels (type 2/3/4) |
| Middle | 345—380 | Most central and northern provinces |
| Bottom | 337 | Narathiwat, Pattani, Yala |
Bangkok's THB 400/day works out to roughly THB 10,400/month at 26 working days (Ministry of Labour, Employsome 2026 guide). That's the legal floor — not a benchmark for any skilled role.
Realistic Salary Bands for 2026
Public job-board averages skew low because they aggregate disclosed salaries across all seniority levels. Use these ranges as starting points, then triangulate against the Robert Walters and Adecco 2026 guides for your specific role.
| Role | Monthly Range (THB) | Notes |
|---|---|---|
| Junior Developer (0—2 yrs) | 30,000 — 50,000 | JobsDB Bangkok avg ~THB 40K for "Software Developer" |
| Senior Developer (5+ yrs) | 80,000 — 150,000 | Data/ERP specialists hit THB 70—80K floor per Adecco 2026 |
| Accountant | 25,000 — 45,000 | Lower band for AP/AR; upper for CPD-licensed |
| HR / Ops Coordinator | 25,000 — 40,000 | Bilingual EN/TH premium ~15% |
| Marketing Manager | 50,000 — 90,000 | Performance/digital trends higher |
| Sales Manager | 60,000 — 120,000 | Base only; commission usually 30—50% of OTE |

The Work Permit Math: 4 Thai Hires Per Foreigner
For a standard (non-BOI) Thai limited company, every foreign work permit requires:
- 4 Thai employees registered with the SSO for at least 3 months
- THB 2 million in registered capital per foreign employee
- The company must be VAT-registered and current on SSO contributions
So if you and one co-founder both want work permits, you need 8 Thai employees and THB 4 million paid-up capital (Belaws, Lex Bangkok).
BOI promotion changes the math. A Board of Investment-promoted company is exempt from the standard 4:1 ratio under Section 26 of the Investment Promotion Act, and service-based BOI projects have no mandatory ratio at all. Manufacturing BOI projects with 100+ staff must keep at least 70% Thai. New BOI rules effective October 2025 for new projects (January 2026 for existing) add minimum income thresholds for foreign hires (PKF Thailand, HLB Thailand).
Recruiting Channels That Actually Work in Bangkok
JobsDB (th.jobsdb.com) is the dominant general-purpose board — highest reach for junior to mid-level roles across functions. Treat it as default.
LinkedIn Thailand works for English-speaking senior roles, MNC-experienced candidates, and tech. Penetration outside Bangkok and outside white-collar functions is shallow — don't expect to fill a sales rep or accountant role from LinkedIn alone.
JobThai indexes more SME and Thai-language roles; useful when you want candidates whose primary working language is Thai.
Recruitment agencies (Robert Walters, Adecco, Michael Page, Manpower) charge 15—25% of the candidate's gross annual salary for contingency placements, and 30—33% for retained executive search (Morgan Newson, Tom Sorensen). For a THB 80,000/month senior developer, a 20% contingency fee is THB 192,000 — budget for it before you brief the agency.
Employment Contract Essentials
Thai contracts have less freedom than US "at-will" — the Labor Protection Act B.E. 2541 (LPA) is mandatory.
- Probation: not defined by statute. Standard practice is 119 days maximum — terminate on day 120 or later and severance under Section 118 is owed (Asanify).
- Working hours: max 8/day and 48/week (42/week for hazardous work).
- Overtime: 1.5x weekday hourly rate; 2x for regular hours on a public holiday; 3x for overtime hours on holidays/rest days. Cap of 36 OT hours/week. Employee consent required (Formichella & Sritawat).
Severance (Section 118) for termination without cause:
| Tenure | Severance |
|---|---|
| 120 days — <1 year | 30 days' wages |
| 1 — <3 years | 90 days |
| 3 — <6 years | 180 days |
| 6 — <10 years | 240 days |
| 10 — <20 years | 300 days |
| 20+ years | 400 days |

Social Security Registration — Same Day You Sign
The moment you sign your first employee, an SSO clock starts. You have 30 days from their start date to:
- Register the company as an employer using Form SSO 1-01
- Register each employee using Form SSO 1-03
Miss the window and the penalty is up to 6 months' imprisonment or a fine up to THB 20,000 (Themis Partner, Benoit & Partners).
Contributions are 5% employer + 5% employee. As of 1 January 2026 the wage ceiling rose to THB 17,500, so the monthly cap moved from THB 750 to THB 875 each side.
You also withhold personal income tax monthly and file PND.1 by the 7th of the following month (15th for e-filing), plus the annual PND.1 Kor summary by end of February (Forvis Mazars).
What Foreign Founders Get Wrong
- Importing "at-will" expectations. Thai labor is not flexible. After day 120, every termination without cause triggers Section 118 severance — there is no negotiating it away in the contract.
- Skipping probation paperwork. A verbal "you're on probation" isn't enough. The 119-day window must be in the signed contract, with clear performance criteria, or it doesn't protect you.
- Underestimating severance accrual. A senior hire at THB 120,000/month who clears 6 years costs THB 960,000 in severance alone if you let them go. Model it.
- Treating the 4:1 ratio as a paperwork problem. It's a hiring plan. Either commit to building a Thai team of 4 before pulling your own work permit, or get BOI promotion.
- Trusting a single salary data point. JobsDB averages, Glassdoor self-reports, and recruiter quotes can diverge by 40%. Triangulate three sources before extending an offer.
