Branch Office vs Representative Office — Which Structure Is Right for You?

Understanding the critical commercial and legal distinctions before you commit

Trading Entity

Branch Office

Non-Trading Entity

Representative Office

May generate revenue in Thailand
May enter into commercial contracts
100% foreign ownership
Foreign Business License required
Subject to corporate income tax 20% on net profit Exempt (no revenue)
May hire foreign employees (Work Permit)
Minimum paid-up capital THB 3,000,000 THB 3,000,000
Parent company liability Unlimited Unlimited
Typical registration timeline 8–14 months 3–6 months

If your primary objective is to generate revenue from Thailand-based clients or contracts, the Branch Office is the appropriate structure. If you require only liaison, sourcing, or market-research functions, a Representative Office may be more efficient and cost-effective. UnionSPACE recommends a consultation before committing to either structure.

Key Legal & Regulatory Parameters of a Thailand Branch Office

Navigating Thailand's Foreign Business Act — our structured approach

Step-by-Step: How to Register a Branch Office in Thailand

Eligibility & Business Scope Assessment

Before preparing any documentation, UnionSPACE conducts a thorough eligibility assessment. This involves confirming that the proposed business activity is permissible under the Foreign Business Act, identifying whether any restrictions or conditions apply, and structuring the business plan in the manner most likely to secure DBD approval.

The Ministry of Commerce retains broad discretion to accept or reject Branch Office applications. A well-structured and commercially credible application — particularly the business plan and declaration of intended activities — is the single most important factor in obtaining approval.

Document Preparation, Notarisation & Consular Legalisation

All constitutional and corporate documents of the foreign parent company must be authenticated in a precise sequence: notarisation in the country of origin, legalisation by the Thai Embassy or Consulate in that country, followed by certification at the Ministry of Foreign Affairs in Bangkok. All documents must be accompanied by certified Thai translations.

UnionSPACE coordinates this multi-jurisdiction process on your behalf, working with our network of certified translators and notarial agents to ensure complete documentary compliance before any filing is made.

DBD Submission & Foreign Business License (FBL) Application

The complete application package — comprising the legalised corporate documents, the appointment letter for the Thailand manager, the business declaration, and the detailed business plan — is submitted to the Department of Business Development (DBD) for consideration.

The DBD may request supplementary information or documentation at any stage of its review. UnionSPACE manages all correspondence and supplementary submissions, ensuring continuity and minimising delays throughout the assessment period.

Upon approval, the DBD issues the Foreign Business License, which formally authorises the Branch Office to conduct the specified activities in Thailand. The Branch Office is thereafter registered in the DBD's commercial registry.

Tax Registration, VAT Certificate & Corporate Bank Account

Following FBL issuance, UnionSPACE registers the Branch Office with the Revenue Department of Thailand for corporate income tax and, where applicable, VAT purposes. A VAT-compliant registered office address — including a landowner approval letter — is provided as part of our service package.

UnionSPACE also prepares all documentation required for opening a Thai corporate bank account and provides a formal letter of introduction to our banking partners. All authorised signatories must appear in person at the bank; foreign signatories will typically require a valid Work Permit prior to account approval.

  • Standard end-to-end timeline: 8 to 14 months from initial instruction to FBL issuance.

Required Documentation for a Thailand Branch Office Application

A complete checklist of documents required by the Department of Business Development (DBD)

  1. Complete Corporate Documentation of the Foreign Head Office

    Including the Certificate of Incorporation, registered capital confirmation, business objectives, Memorandum and Articles of Association, official registered address, list of directors and authorised signatories, and the current shareholder register. All documents must be notarised and legalised.

  2. Appointment Letter Issued by the Foreign Head Office

    An official letter executed by the authorised signatory of the parent company, designating a named individual — who may be a foreign national or Thai citizen — as the person in charge of the Branch Office's operations in Thailand.

  3. Identification Documents of the Appointed Manager

    A copy of the appointed individual's valid passport (for foreign nationals) or national identification card (for Thai nationals), together with proof of address in Thailand, Thai Visa, or evidence of permission to enter Thailand.

  4. Declaration of Eligibility under the Foreign Business Act

    A formal declaration, signed by the foreign parent company, certifying that the applicant, directors, managers, and appointed manager satisfy all qualifications and are not subject to any prohibitions under Section 16 of the Foreign Business Act B.E. 2542 (1999).

  5. Location Map of the Proposed Place of Business

    A map or diagram indicating the approximate location of the Branch Office's principal place of business in Thailand, including the street address.

  6. Power of Attorney (if applicable)

    Required where a third party — such as UnionSPACE — has been authorised by the applicant to act on its behalf in connection with the establishment of the Branch Office.

  7. Supporting Financial & Operational Documents

    Including the head office's audited financial statements for the preceding three financial years, confirmation of the salary and remuneration of the Thailand-based manager, and any other supporting evidence the DBD may require.

  8. Detailed Business Declaration & Plan

    A comprehensive declaration covering all of the following matters:

    1. The type and scope of business activities for which the FBL application is made, including the operational stages
    2. A three-year projection of expenditure on fixed assets and operational costs in Thailand
    3. The intended scale of operations
    4. The anticipated size of the Thai workforce
    5. A plan for the import of foreign technology and technology transfer
    6. Research and development plans, if applicable, with a detailed working plan
    7. The intended period of business operation in Thailand
    8. The overall economic benefit Thailand is expected to derive from the Branch Office's operations
    9. The projected sources of income and estimated revenue from the Branch Office's activities in Thailand

Frequently Asked Questions — Branch Office Registration in Thailand

Authoritative answers to the questions most commonly raised by international businesses

A Branch Office is an extension of the foreign parent company — not a separate legal entity. The parent bears unlimited liability for all acts and obligations of the Branch. A subsidiary (typically a Thai limited company) is a distinct legal entity in which the foreign parent holds shares; it has its own legal personality and liability is limited to the subscribed capital. Each structure suits different commercial and risk-management objectives, and the appropriate choice will depend on factors including the nature of the business, the extent of Thai activities, and the parent company's risk appetite.

Yes. This is the principal commercial distinction between a Branch Office and a Representative Office. A Branch Office is a trading entity and is authorised under its Foreign Business License to generate revenue, enter into commercial contracts, and conduct the business activities specified in its FBL. Revenue is subject to Thai corporate income tax at a rate of 20% on net profit, with potential relief available under applicable tax treaties.

The end-to-end process — from initial document preparation through to Foreign Business License issuance — typically takes 8 to 14 months. The extended timeline reflects the multi-step document legalisation process (notarisation, consular attestation, and Ministry of Foreign Affairs certification), the preparation of the business plan and declaration, and the DBD's own review and assessment period. Delays in document preparation in the home country are the most common cause of timeline extensions.

The Foreign Business Act requires a minimum total capital of THB 3,000,000 to be remitted into Thailand. This capital is brought in over time in tranches: the first tranche of not less than 25% (THB 750,000) must be remitted before the Branch Office can begin operations; subsequent tranches are remitted on a schedule prescribed by the DBD. Capital remittances are evidenced by a Foreign Exchange Transaction Form from the receiving bank in Thailand.

Yes. The Department of Business Development retains broad statutory discretion to refuse applications that it considers contrary to Thailand's economic interests, national security, or public policy. In practice, applications are most likely to encounter difficulties where the proposed business activities overlap with areas of sensitivity under the Foreign Business Act, where the business plan lacks commercial credibility, or where documentation is incomplete or incorrectly prepared. UnionSPACE's rigorous pre-submission preparation is designed specifically to minimise these risks.

Physical presence in Thailand is not required for the registration process itself, provided that appropriate powers of attorney and notarised authorisations have been executed. UnionSPACE handles all filings and correspondence with the DBD on your behalf. The appointed manager for the Branch Office must, however, be physically based in Thailand for the purposes of the registration and ongoing compliance obligations.

A Branch Office operating under a Foreign Business License is subject to a 1:1 Thai-to-foreign employee ratio for Work Permit purposes — meaning one Thai employee is sufficient to support one Work Permit application for a foreign national. This is notably more favourable than the 4:1 ratio typically applicable to standard Thai limited companies. Foreign employees will require a Non-Immigrant B Visa followed by a Work Permit, both of which UnionSPACE can assist with as additional services.
