Company Registration in Thailand

A Thai Company Limited is the most common structure for foreigners doing business in Thailand. Requires minimum 3 shareholders (can be 2 Thai + 1 foreign). Registered capital of 2 million THB is standard for obtaining one work permit. Thai nationals must hold at least 51% of shares unless you qualify for BOI promotion or Treaty of Amity (US citizens). Costs 30,000–50,000 THB through a lawyer including registration, tax ID, and VAT registration.

The 51/49 structure uses Thai nominees holding 51% while you control 49% plus voting rights through preference shares. Legally gray but extremely common. Good lawyers structure this with shareholder agreements, power of attorney, and board control favoring the foreigner. Costs 40,000–80,000 THB to set up properly. Annual maintenance: 15,000–30,000 THB for accounting and tax filings. Risk: nominees can theoretically claim ownership, so choose a reputable law firm that provides their own nominees.

The Board of Investment (BOI) allows 100% foreign ownership in promoted business categories: software development, digital content, R&D, tourism services, and more. Benefits include tax holidays (3–8 years corporate tax exemption), work permit facilitation, and land ownership rights. Application takes 2–4 months. Minimum investment varies by category — typically 1–5 million THB. Best for tech companies, manufacturing, and serious long-term businesses.

American citizens can own 100% of a Thai company under the US-Thailand Treaty of Amity (1966). Covers most business activities except specific restricted ones (land, media, agriculture). Application through the American Chamber of Commerce in Bangkok — processing 4–8 weeks. Cost: 30,000–50,000 THB for setup plus AmCham fees. One of the most underutilized advantages for American entrepreneurs in Thailand. Requires maintaining AmCham membership (annual fee).

Company registration: 10,000–15,000 THB (government fees). Lawyer/agency fees: 20,000–50,000 THB. Registered office rental: 3,000–8,000 THB/month (can use virtual office). Company seal/stamp: 500–1,500 THB. Tax registration: included or 2,000–5,000 THB. VAT registration: free but requires inspection. Work permit: 3,000–5,000 THB. Social security registration: free. Total realistic budget: 50,000–100,000 THB for everything including first year accounting.

Week 1: Company name reservation (1–2 days), memorandum of association filing, shareholder meeting. Week 2: Company registration at DBD (Department of Business Development), tax ID application, corporate bank account opening. Week 3: VAT registration (if applicable), social security registration, work permit application. Week 4: Work permit issued, business operational. Delays happen with bank accounts (some banks take 2–4 weeks) and VAT inspections.

Passport copies of all shareholders (notarized). Proof of registered office (lease agreement or virtual office contract). Company objectives list (up to 20+ objectives recommended for flexibility). Articles of association. Shareholder meeting minutes. Map showing office location. Director's criminal background check for work permit. Photos of office (for VAT inspection). Some banks require business plan and projected financials.

Monthly: withholding tax filings (PND 1, PND 3, PND 53), VAT filing (PP 30), social security contributions. Annually: corporate income tax (PND 50 — filed within 150 days of fiscal year end), half-year tax (PND 51), financial statements audit (if capital exceeds 5M THB), annual shareholder meeting, DBD filing. Cost for accounting firm: 8,000–20,000 THB/month depending on transaction volume. Penalties for late filing: 1,000–200,000 THB.

Your company must employ 4 Thai staff per 1 foreign work permit (2 million THB registered capital per permit). Minimum salary for work permit: 50,000 THB/month for citizens of developed countries. Work permit tied to your company — if the company closes, the permit is canceled. Processing: 2–4 weeks after company registration is complete. Must carry work permit at all times (or digital copy). Renewable annually alongside your Non-B visa extension.

Don't use the cheapest lawyer — bad structuring costs more to fix later. Don't register with minimum capital (5,000 THB) — immigration requires 2 million per work permit. Don't skip the shareholder agreement — it protects your control. Don't ignore monthly tax filings — penalties accumulate fast. Don't use your condo as registered office without landlord permission. Don't start operating before registration is complete. Don't forget to register for social security within 30 days of hiring.

Sole proprietorship: Thai nationals only. Branch office: for existing foreign companies expanding to Thailand — complex but allows 100% foreign ownership. Representative office: limited to non-revenue activities (market research, sourcing). Partnership: registered ordinary or limited partnership, simpler than LLC but less protection. Freelance/consultant: no formal structure, use personal income tax — but technically requires work permit for any work done in Thailand.
