Starting a Business in Thailand — Foreigner's Guide
Thailand offers real business opportunities for foreign entrepreneurs — but the legal landscape requires careful navigation. Here is what you need to know.
Quick Answer
Can foreigners start a business in Thailand?
Yes, but with restrictions. The Foreign Business Act limits foreign ownership to 49% in most sectors. 100% foreign ownership is possible via BOI promotion, Treaty of Amity (US citizens only), or a Foreign Business Licence for specific activities. Using illegal Thai nominees is a common mistake with serious legal consequences. Always work with a qualified Thai business attorney.
Thai LLC Registration
The most common business structure for foreigners in Thailand is the Thai Limited Company (Borisat Chamgad). Registration is done with the Department of Business Development (DBD) under the Ministry of Commerce. Key requirements: minimum 3 shareholders (can include foreigners), registered capital (typically 1–2 million THB for work permit purposes), a registered Thai address, and articles of association.
The registration process takes approximately 3–7 business days with a qualified agent. Costs including government fees and agent fees typically run 15,000–30,000 THB. The company requires an annual general meeting, audited accounts, and annual registration renewal with DBD.
Foreign Business Act & Ownership Structures
The Foreign Business Act B.E. 2542 (1999) divides restricted business activities into three lists. List 1 (completely prohibited to foreigners — media, agriculture, Thai antiques trading), List 2 (permitted with Cabinet approval, national security related), and List 3 (permitted with a Foreign Business Licence — most service businesses). A business not on any list can be majority foreign-owned.
For tech, software, and digital businesses, Thailand has created specific exemptions and BOI categories. Many online businesses operating internationally may not be restricted under the FBA at all — a legal opinion is worthwhile.

BOI Promotion
Thailand's Board of Investment is one of the most attractive incentive schemes in Southeast Asia for qualifying businesses. Targeted sectors include: digital technology and software, medical devices and services, food processing and agriculture, advanced manufacturing, logistics and distribution, and creative industries.
BOI benefits can include 100% foreign ownership, corporate tax holidays of 3–8 years, import duty exemptions, and a streamlined "smart visa" and work permit process. BOI applications require a business plan, investment commitment (minimum thresholds apply by category), and Thai employment commitments.
Business Visas & Work Permits
To legally work in Thailand, foreigners need both a Non-Immigrant B visa and a Work Permit. The Non-B visa is typically obtained at a Thai embassy in your home country or a neighbouring country (border run visas are no longer reliable for work permit purposes). Work permits are issued by the Department of Employment and require the employing company to meet staff ratios and capital requirements.
The Thailand SMART Visa is an alternative for investors, executives, and specialists in targeted industries — it grants a 4-year visa without the traditional work permit requirement and allows holders to report to immigration annually rather than every 90 days.
