With flexible structures, targeted tax breaks and new digital processes, launching as a foreigner has never offered more opportunity or required clearer compliance.

Key Takeaways

  • Foreign ownership is capped at 49% for most sectors under the Thai Foreign Business Act, unless you secure BOI promotion or a Foreign Business License for full control and added incentives.
  • BOI (Board of Investment) promotion enables 100% foreign ownership and offers major tax incentives for businesses in technology, export, or high-impact sectors.
  • Minimum capital requirements vary: Standard companies need at least 50,000 THB, but plans to employ foreigners or support work permits require a minimum of 2 million THB per foreign employee.
  • Private limited companies are the most flexible structure for foreign-owned SMEs, offering limited liability and clear legal framework when correctly structured.
  • Successful company registration requires: Name reservation online, Thai business address, precise documentation and official review by the Department of Business Development
  • A Non-Immigrant B Visa plus work permit are essential for foreign directors and staff, with BOI or SMART Visa options available for innovation sectors or investors.
  • Opening a business bank account demands a company certificate, tax ID, passport, and work permit, with smoother processes when involving a Thai director or professional advisor.
  • Ongoing compliance is non-negotiable: Annual financial filings, VAT registration over 1.8 million THB turnover, and timely work permit renewals keep your business legally secure and audit-ready.

Foreign Ownership Restrictions & Opportunities

Foreigners face clear limits when starting a small business in Thailand, under the Foreign Business Act: only 49% direct ownership is allowed in most sectors, with at least 51% owned by Thai nationals.

Key sectors such as media, agriculture, and certain services are officially restricted for foreign involvement without special approval.

Consider these options for majority foreign ownership or incentives:

  • Board of Investment (BOI) promotion: Allows up to 100% foreign ownership and offers tax incentives for businesses in technology, manufacturing, or export.
  • Foreign Business License (FBL): Enables majority ownership in unique or non-competitive sectors, but applications are rarely approved without a strong case.

Avoid illegal nominee shareholder schemes: these are strictly prohibited and can result in serious penalties under Thai law.

Minimum Capital & Compliance Requirements

Registered capital requirements depend on your business approach:

  • Standard company: Minimum 50,000 THB
  • Employing foreign staff or supporting work permits: Minimum 2 million THB per foreign employee
  • BOI-promoted sectors: As required by BOI, typically higher but with incentives

You must also:

  • Register for tax with the Revenue Department
  • Provide an official Thai business address
  • Meet requirements for directors and Thai shareholders

Industry-specific licenses may apply, from tourism to food services.

Understanding these regulations helps you secure long-term success and unlock market opportunities. Early legal guidance ensures your structure, documents, and ongoing compliance are correct from the start.

Choosing the Best Business Structure

Best Company Structures for Foreigners

Foreigners in Thailand can select from several business structures, each with differing requirements and benefits.

The most common options include:

  • Thai Private Limited Company: Requires at least two shareholders (at least 51% Thai-owned unless under BOI promotion), one director, and limits liability to investment amount.
  • Representative Office: Permits only non-revenue-generating activities like market research or product sourcing, with no sales or profit allowed.
  • Branch Office: Allows foreign parent companies to conduct business in approved sectors, needing a Foreign Business License in most cases.
  • Partnership: General partnerships require a Thai majority, while limited partnerships need at least one Thai partner with unlimited liability.

Private limited companies remain the top choice for small and medium-sized enterprises due to their flexible ownership and clear legal framework.

  • Renewing your Non-B Visa and work permit on time with updated addresses and employment details
  • Keeping all records and tax filings available for audits

Setting Up Small Business Operations

Opening a Business Bank Account in Thailand

Bank policies can differ. Some banks are more receptive if you bring a Thai director or use the company’s accountant during the process.

Common obstacles include language barriers, stricter address verification, and additional forms. Many business owners resolve these by:

  • Using an accountant or legal advisor to facilitate
  • Preparing all documents in advance
  • Selecting banks with English-speaking staff and SME experience
