Starting a Business in Thailand as a Foreigner: 5 Real Pathways in 2025

Thailand issued a record 12,573 work permits to foreign entrepreneurs in 2024 — up 18% year-on-year, according to the Department of Employment. The Kingdom is actively courting foreign capital and expertise. Yet the gap between 'wanting to launch' and actually operating is filled with licenses, restrictions, and mandatory local partners.

What Business Activities Are Open to Foreigners?

The rulebook is the Foreign Business Act (FBA) of 1999, which divides all activities into three lists. List 1 is fully closed: media, land trading, agriculture. List 2 requires Cabinet approval. List 3 — the broadest — demands a license from the Department of Business Development.

Retail, restaurants, construction, accounting, and tourism services all fall under List 3. You cannot simply register a company and start trading. You need either a Foreign Business License (FBL) or a Thai-majority ownership structure.

Activities operating outside FBA restrictions include:

• IT development and SaaS — software firms are exempt
• Export manufacturing — with a BOI license
• Consulting and professional services — via BOI promotion
• Medical and wellness tourism — through BOI-approved categories
• Digital marketing — when services are delivered outside Thailand

How to Own 100% of Your Company

The most direct route is the Board of Investment (BOI), which grants full foreign ownership, up to 8 years of tax holidays, and streamlined work permits. In 2023, BOI approved 2,196 projects worth approximately $20.6 billion.

The Eastern Economic Corridor (EEC) offers even stronger incentives — up to 13 years of corporate tax exemption. US citizens can use the Treaty of Amity to operate on equal footing with Thai nationals.

The most common structure for small business is a Thai Co., Ltd. with Thai shareholders holding at least 51%. Nominee arrangements are illegal — penalties reach 1 million baht with possible imprisonment.

Where the Real Opportunities Are

Thailand's SMART Visa gives tech entrepreneurs a 4-year visa without a separate work permit. IT startups can apply via DEPA or BOI category 5.7 to gain 100% ownership and zero corporate tax for up to 8 years.

Medical tourism is equally compelling. Thailand welcomed 3.47 million medical tourists in 2023, generating 40 billion baht in revenue. Foreign founders are building aggregator platforms connecting patients with clinics — classified as digital services, requiring no medical license.

Hiring Thai Staff

The minimum wage stands at 370 baht per day, rising to 400 baht in 2025. Each foreign work permit requires hiring at least 4 Thai employees. Note: the probation period is capped at 119 days — dismissal after day 120 triggers mandatory severance.

Key Checks Before Launch

Before signing any agreement, conduct:

• Partner due diligence via DBD records
• Legal structure audit to confirm FBA compliance
• Tax planning — Thailand now taxes foreign-earned income remitted locally
• Property title checks if leasing premises

Thailand offers genuine opportunity — but only for those who understand the rules. Begin with a licensed Thai lawyer specialising in FBA and BOI. A comprehensive consultation costs 30,000–80,000 baht — far less than the cost of a mistake.
