Branch Office in Thailand

A Thai branch is part of an existing foreign company. It is not a newly incorporated Thai subsidiary. The parent remains responsible for the branch’s obligations, so the decision affects more than the local office budget.

Before choosing this structure, identify who will sign contracts, deliver services, employ staff, invoice customers and bear claims. Ask counsel in Thailand and the parent’s jurisdiction to assess liability, tax and authority together. A branch can be useful where the parent needs to undertake a defined Thai operation, but it should not be selected solely because incorporation appears simpler.

A foreign company falls within the Foreign Business Act’s foreigner definition. Whether an activity is restricted, exempt or subject to a separate sector law needs to be assessed on the real work undertaken. A broad description such as “consulting” does not resolve that assessment.

Where required, obtain the appropriate Foreign Business Licence or certificate before operating the restricted business. Treaty and investment-promotion routes have their own eligibility and conditions. A tax number, bank account or approved company name does not authorise a restricted activity.

Give the adviser a transaction map: customers, deliverables, location of staff, contracting entity and money flows. Request a written explanation of the applicable route and any boundaries on what the branch can do.

Expect to establish the parent’s existence, constitutional arrangements and signing authority. Ask DBD or the receiving adviser for the current checklist covering corporate records, authorising resolutions, powers of attorney, the branch manager, proposed address and activity.

Foreign documents may need translation, certification or legalisation. Confirm the exact route, document age and accepted format for the issuing country before paying for a package. Do not assume that an apostille, electronic extract or notarised copy is accepted in every case.

Check that names, registration numbers, addresses and signing conditions match across the application. Record who can bind the parent, the limits of that authority and how a replacement manager will be appointed. Keep usable copies in both locations.

Capital and remittance conditions can depend on the activity, permission and applicable regulations. Obtain a calculation for the actual operation and retain evidence of funds brought into Thailand. Do not treat a headline minimum quoted for another company as the branch’s complete funding requirement.

Build a separate operating forecast covering premises, payroll, professional fees, insurance, licences, tax and a delay before customer collections. Distinguish capital remittances, parent funding, revenue and reimbursements in the accounts.

Ask the bank what corporate, ownership, authority and local-operation evidence it needs. Establish payment limits and independent approval rather than letting a local representative control every bank and filing credential.

Confirm taxpayer registration and the tax treatment of the branch’s Thai activities before the first contract. Review corporate income tax, VAT, withholding, parent charges and any remittance of profits. The outcome depends on the facts, applicable law and any relevant treaty.

Analyse work performed or contracts signed by the head office as well as invoices issued locally. Moving an invoice offshore does not settle whether income is connected with the Thai operation. Ask for support for allocations and related-party charges, with records the branch can actually produce.

The linked Revenue Department identification page is older background and includes historical rate examples. Use current advice for rates, forms and treaty treatment; do not copy its dated tax tables into the financial model.

Maintain records that clearly identify the Thai operation and reconcile them with parent-company reporting. Appoint appropriate accounting support and arrange the required audit and financial-statement filing process. A parent’s overseas consolidated audit does not by itself complete Thai obligations.

Current DBD guidance groups foreign juristic persons operating in Thailand with entities required to submit financial statements within five months of the accounting-period end. Confirm the branch’s actual filing category, accounting period and accepted submission through DBD e-Filing. Revenue Department returns are separate obligations.

Keep official acknowledgements, receipts, capital evidence and correspondence. Assign an owner for changes in address, activity, manager or parent particulars, and check whether they require a notification or amended permission.

The branch’s business permission does not automatically authorise foreign personnel to work. Confirm the correct immigration category, employer, role and work-authorisation process before anyone begins duties. An appointment as branch manager does not settle those individual requirements.

Set up lawful employment terms, payroll, social-security arrangements where applicable and controls over personal data. For staff seconded by the parent, agree who directs the work, pays salary and bears costs, then have the tax and employment treatment reviewed.

Before expanding the activity, relocating or changing the contracting model, check the branch’s existing permission and related registrations. A new revenue line may require more than changing a website or invoice template.

Closure should include outstanding contracts, employees, tax, accounts, creditors, licences and retention of records. Stopping sales or allowing the lease to expire is not a complete closure process. Agree a sequence with advisers and retain proof that each authority’s requirements have been completed.
