What Are the Requirements for Registering a Company in Thailand? A Step-by-Step Guide to Setting Up Your Thai Business

Setting up a company in Thailand isn’t as simple as having an idea and expecting it to materialize. Don’t assume that hiring an agent, paying a fee, and waiting a few weeks will automatically yield your business license-only to get stuck mid-process due to issues with shareholder structure, paid-up capital requirements, or office address verification. While Thai company registration isn’t overly complex, every step has clear, non-negotiable requirements; overlooking even one detail can result in application rejection and costly delays.

Basic Eligibility Requirements

1. At least one director must be a Thai national aged 20 or older, with no record of bankruptcy or court-imposed disqualification from serving as a director;

2. A minimum of one shareholder is required-this may be a foreign individual or legal entity. However, if all shareholders are foreign, the business must qualify for exemption under the restrictions outlined in the Foreign Business Act’s prohibited/regulated industry list;

3. Registered capital must be denominated in Thai Baht. While there is no statutory minimum, we recommend setting it at no less than THB 100,000. At least 25% of this amount must be fully paid up upon registration, supported by a bank-issued capital verification letter;

4. The company must maintain a genuine, verifiable registered office address within Thailand. Virtual offices or “address-only” service arrangements are not acceptable. You must provide both a signed letter of consent from the property owner and a certified copy of the title deed or lease agreement;

Core Application Documents

1. Certified copies of the first page and latest visa page of each shareholder’s and director’s valid passport (if holding a tourist visa, additional documentation justifying funding sources and business rationale is required);

2. Articles of Association, clearly specifying the scope of business operations, shareholding ratios, and directors’ powers and responsibilities-signed by all shareholders and notarized;

3. Consent to Act as Director forms, individually signed in original ink by each director, including full identification number;

4. Proof of registered office address: either a valid lease agreement or title deed, accompanied by a signed Letter of Consent from the property owner (with a certified copy of the owner’s ID attached);

5. Bank Letter of Deposit confirming that the required capital has been deposited into a temporary corporate account opened in the company’s name, with clear and traceable funding sources;

Key Process Milestones

1. Submit your proposed company name to the Department of Business Development (DBD) for name availability check and pre-approval-results typically issued within 1-2 business days;

2. Draft and execute the Articles of Association; all foreign shareholders must sign before a Thai embassy/consulate in their home country or a notary public in Thailand;

3. Submit the complete application package-both hardcopy and electronic-to the DBD, including the name approval receipt, Articles of Association, director consents, address proof, and bank deposit letter;

4. Upon approval, the DBD issues the Certificate of Incorporation and Tax Identification Number (Tax ID). The statutory processing time is seven working days;

5. Within 30 days of receiving the Certificate of Incorporation, you must register for corporate income tax with the local Revenue Department, open a corporate bank account, and complete the preliminary annual filing registration;

Common Reasons for Rejection

Company name includes restricted terms (e.g., “Thailand,” “National,” “Royal”) without prior authorization;

Bank deposit letter fails to state explicitly that funds are “for company registration purposes only”;

Lease agreement shows a commencement date earlier than the company registration date-or lacks the property owner’s signed consent page;

Passport validity for foreign shareholders is less than six months, or the visa type held is clearly inconsistent with the intended business activity;

Ongoing Compliance Obligations

Submit audited financial statements and corporate income tax returns annually by May 31;

Each board term lasts no longer than five years; reappointment requires submission of a newly signed Consent to Act as Director;

Any changes to registered capital, directors, or registered office address must be reported to the DBD within 15 days of the change;

The above outlines the core requirements and practical steps for registering a company in Thailand. If you have further questions-or wish to explore industry-specific entry restrictions, tax-filing timelines, or details on opening a local corporate bank account-we strongly recommend consulting, in advance, a qualified Thai-certified accountant or licensed legal counsel familiar with your specific business model.
