Branch Office Registration for Foreign Companies in Thailand in Thailand
A branch is the same legal person as the head office — simpler to set up, but the parent bears full liability.
Quick answer
A foreign branch is not a separate legal entity — the head office is fully liable for all branch debts and obligations. The registration goes to the Department of Business Development, requiring an appointed branch representative and consularised head-office documents. If the activity falls under the Foreign Business Act lists, a Foreign Business Licence is needed first. Contact our team for a quotation.

How it works
5-step process
- 1
Map activities against the FBA lists
We check whether the branch's planned activities fall under the restricted lists of the Foreign Business Act, which determines whether a Foreign Business Licence must precede registration.
- 2
Prepare head-office documents
Documents are obtained in the home country, notarised, legalised at the Thai consulate, and translated into Thai by a certified translator.
- 3
Appoint the branch representative
The appointment letter defines the representative's authority precisely, since their acts bind the head office directly.
- 4
File with the Department of Business Development
The application set is filed with supporting documents; processing time depends on document completeness and the authority's queue — we state the expected timeframe in our quotation.
- 5
Tax registration and bank account
We obtain the tax ID, register for VAT when the threshold is met, and open a bank account in the branch's name.
FAQ
Frequently asked questions
How does a branch differ from a subsidiary?
A branch is the same legal person as the head office, which bears full liability for branch debts. A subsidiary is a separate entity with liability limited to its capital, but requires at least two shareholders.
Does every branch need a Foreign Business Licence?
Not always. It depends on whether the activity appears in the Foreign Business Act's annexed lists. Some activities, such as manufacturing for export, may be exempt. We verify this before filing.
Is there a minimum capital for a branch?
For branches requiring an FBL, the law sets minimum capital at no less than 3 million baht or 25% of estimated three-year expenses, whichever is higher. For activities not requiring an FBL, check the current criteria with the Department of Business Development.
Must the branch representative be Thai?
No, but a foreign representative needs a proper visa and work permit, plus a Thai address for receiving official correspondence.
