What Do You Need to Register a Company in Thailand? A Step-by-Step Guide to All Required Documents and Procedures

Establishing a company in Thailand is far more complex than simply filling out a few forms and paying some fees. In practice, each step-including selecting the appropriate legal structure, determining shareholder composition, arranging registered capital, and fulfilling local compliance obligations-directly impacts the stability and flexibility of your future operations. Don’t assume everything is settled once registration is complete; you may later encounter unexpected roadblocks-such as being denied a corporate bank account, hitting delays during tax registration, or having your office address rejected. These issues often stem from inconsistencies or mismatches in preliminary documentation or eligibility criteria.

Core Prerequisite: Confirm Company Type and Eligible Entity

1. Most foreign applicants opt for a “Private Limited Company,” the most common and legally well-defined business entity in Thailand;

2. If foreign natural persons or legal entities hold more than 50% of the shares, additional requirements under the Foreign Business Act (FBA) apply; certain industries mandate obtaining a Foreign Business License (FBL);

3. Local partnerships or sole proprietorships, while simpler to register, carry unlimited personal liability and cannot open corporate bank accounts-making them impractical for substantive commercial operations.

Essential Document Checklist (Ordered by Submission Sequence)

1. Company Name Reservation & Verification: Submit three alternative names via the Department of Business Development (DBD) online system. The system automatically checks for duplication or prohibited terms; approved names are reserved for 30 days;

2. Articles of Association: Clearly define share structure, directors’ rights and responsibilities, profit distribution mechanisms, etc.; must be signed by all shareholders and notarized;

3. Identity Documents for Shareholders and Directors: Foreign individuals must provide full-page passport scans (including visa pages) and proof of address (e.g., utility bills or bank statements issued within the past six months); Thai nationals must submit copies of their national ID cards and household registration documents;

4. Registered Office Address Proof: Must be a verifiable commercial address-submit either a lease agreement or property title deed. The DBD may conduct on-site verification; if using a virtual office service, confirm whether it holds official DBD accreditation;

5. Registered Capital Verification: Minimum THB 500,000, fully deposited into a designated Thai bank account prior to registration. The bank must issue an official “Registered Capital Deposit Certificate”; funds must remain untouched until registration is finalized.

Key Process Milestones

1. Submit Registration Application to the DBD: Complete Form BorJor 5 online and upload all required documents-review typically takes 3-5 working days;

2. Receive the Company Affiliation Certificate: A physical document bearing the DBD’s official seal, including the company registration number (Tax ID), incorporation date, and details of the authorized representative;

3. Complete Tax Registration: Present the Company Affiliation Certificate at the Revenue Department to obtain the Tax Registration Certificate (PND.20) and simultaneously activate the electronic filing system (e-Filing);

4. Open a Corporate Bank Account: The authorized representative must attend in person, bringing the Company Affiliation Certificate, Tax Registration Certificate, directors’ passports, and proof of address. Some banks additionally request a brief business plan summary or evidence of initial commercial contracts.

Important Notes

1. At least one director must be a Thai national, holding a valid Thai ID card and free from bankruptcy proceedings or criminal convictions;

2. The first general meeting must be held within 90 days of incorporation, with formal minutes prepared and retained on file;

3. Annual financial statements must be submitted to the DBD, and corporate income tax returns filed by April 30 of the following year;

4. For businesses operating in restricted sectors-including import/export, retail, education, and healthcare-confirm in advance whether the FBL has been explicitly included in the company’s stated scope of business activities.

The above outlines the fundamental pathway and practical considerations for registering a company in Thailand.
