Business & Investment
Your comprehensive guide to company structures, registration, visas, taxes, and the real constraints foreign founders face.
Starting a business in Thailand offers immense potential, but the regulatory landscape for foreign investors is strict and complex. The process involves navigating legal structures, foreign ownership laws, visas, corporate taxes, and meticulous paperwork.
This page is orientation for founders and operators — not legal advice. Company, visa, and tax rules change; verify current requirements with licensed Thai counsel and the relevant authorities before you act.
Part 1
Starting as a foreign national means picking a structure that fits ownership limits, liability, and control — not just the fastest DBD filing.
The most popular choice for foreign investors. Requires at least two shareholders. While Thai nationals typically hold majority shares (51%) for general businesses, foreign investors can structure voting rights securely when counsel designs the articles carefully.
Owned and managed by two or more individuals. Depending on the partnership type, managing partners may bear personal liability for obligations.
Used by foreign corporations for non-revenue-generating tasks like sourcing or market research. It cannot generate local revenue, and all operational funds must come from the headquarters.
Allows a foreign company to conduct business in Thailand under its own name and generate revenue, while remaining legally bound to the foreign parent. Additional licenses may be required under the Foreign Business Act.
Provides administrative and coordination support to regional branches without generating local income.
Allows US citizens to hold majority or full ownership in specific business categories in Thailand — a major exception to the usual foreign-ownership caps.
Works similarly for eligible Australian nationals in covered sectors, opening majority or full ownership where domestic rules would otherwise limit foreigners.
Part 2
Every step in Thailand’s corporate registration needs precise documentation, approvals, and signatures. Skipping steps usually means rejection — not a quick fix later.
Decide between a limited company, branch, or alternative structure while factoring in foreign ownership restrictions.
Submit your proposed name to the Department of Business Development (DBD). It must follow strict naming conventions and include “Limited Company.”
Draft the Memorandum of Association (MOA), shareholder details, and statutory meeting documentation.
File all documents with the DBD to officially establish legal entity status.
Mandatory if projected annual revenue exceeds 1.8 million THB or if you plan to sponsor work permits.
Required if your business is majority foreign-owned and operates in a restricted sector.
Eligible industries can secure tax incentives, tax holidays, and — in many cases — 100% foreign ownership.
Part 3
Operating legally requires the right personal status. You cannot run a company on a tourist visa.
Must be secured before entering Thailand to establish or operate a business. A company alone does not grant the right to work or stay.
Mandatory for foreign directors and employees — even company directors are not exempt. Visa and work permit are a pair.
Paid-up capital typically required to sponsor one foreign work permit
Thai employees per foreign work permit (standard company compliance ratio)
Ratios and capital thresholds can vary by sector, BOI status, and current regulations — confirm before you hire or apply.
Part 4
Registration is only the start. Ongoing tax and payroll compliance is where many foreign-owned companies stumble.
Standard rate for most companies. Incentives or BOI promotions may change the picture for eligible activities.
Applies once revenue reaches the legal threshold — or earlier if you register voluntarily for work-permit sponsorship.
Maintain certified bookkeeping, file annual financial statements, and remit social security for local employees without gaps.
Part 5
Incorporating is only part of the journey. Foreign nationals face constraints that Thai-owned businesses do not.
Many industries limit foreign ownership to 49% unless protected by a treaty or BOI promotion. Nominee shareholding schemes are illegal and high-risk.
Foreigners generally cannot own land directly. Long-term leases or BOI-approved corporate structures are the common lawful workarounds.
Strict rules apply to corporate income tax, VAT, and employee tax withholdings. Late or incorrect filings compound quickly.
Part 6
Thailand’s corporate rules do not reward trial and error. Getting the structure right once is cheaper than unwinding a bad one later.
Mistakes during registration can delay a launch by months — or leave the company unable to sponsor visas, open bank accounts, or operate in its intended sector.
An experienced legal and accounting team helps you choose a lawful structure, secure eligible incentives (treaty or BOI where they apply), and stay compliant on capital, employment ratios, and filings.

Part 7
Quick answers founders ask most often — still orientation, not a substitute for counsel.
Standard limited companies take 3 to 5 weeks. BOI-promoted or Foreign Business License applications can take up to 120 days.
A minimum of two shareholders is required for a Thai Limited Company.
Direct foreign land ownership is restricted. Companies can lease land or hold it through qualifying corporate structures, or via BOI promotion depending on business activities.
Not always. If your business is BOI-promoted or covered under the US-Thai Treaty of Amity, a Thai partner is not mandatory. Otherwise, Thai law generally requires at least 51% Thai ownership for restricted sectors.
Yes, but only under specific exemptions such as US citizenship (Treaty of Amity), Australian citizenship (TAFTA), or official BOI promotion. Otherwise, foreign ownership is capped at 49%.
Sectors such as media, agriculture, and specific service industries are restricted under List 1 of the Foreign Business Act, requiring an FBL, BOI approval, or complete prohibition.
