Setting up a business in Thailand: from research to opening

Validate the business, confirm a lawful structure and activity, then sequence registration, premises, approvals, banking, tax and staffing. Open only when essential permissions and operating controls are ready. Assign accounts, filings, renewals and change responsibilities before the first busy month.

1. Validate the offer before committing the setup budget Define the customer, problem, product or service, location and route to market.
2. Check activity and ownership feasibility Map the actual activities to the Foreign Business Act and relevant sector rules.
3. Choose the entity and governance Compare a limited company, partnership, foreign branch and qualifying representative office against liability, permitted activity, funding, tax, management and exit.

Find what you need

Use a section below to plan your next step.

1. Validate the offer before committing the setup budget

Define the customer, problem, product or service, location and route to market. Test the assumptions that could make the business fail: demand, willingness to pay, delivery capacity, supplier reliability and customer-acquisition cost. Use dated evidence and current quotes rather than a national growth headline.

Build a plan with startup costs, recurring costs, cash collections, tax and a plausible delay or downside. Set a limit on the next commitment and specify what evidence is needed to continue. Any trial or pilot must itself be lawful; research is not permission to start regulated trading.

3. Choose the entity and governance

Compare a limited company, partnership, foreign branch and qualifying representative office against liability, permitted activity, funding, tax, management and exit. A representative office is non-trading; a branch exposes the parent; partnership roles can involve unlimited liability.

Use genuine owners and documented funding. Agree signing powers, reserved decisions, further investment, profit distribution, information access, deadlock and departure. Put the appropriate terms into documents reviewed for the chosen form rather than relying on an informal understanding between founders.

4. Check the site and permission dependencies

Confirm that the premises can support the actual activity before an inflexible lease or fit-out. Review landlord rights and consent, building use, local permissions, safety, health, environment, utilities and access as relevant. A former tenant’s licence or nearby business is not proof of suitability for your entity.

List the approvals, issuing offices, documents, inspection requirements and dependencies. Identify which need a formed entity, completed premises, qualified person or earlier consent. Put critical approval conditions into the commercial plan and contracts where appropriate.

5. Complete the current registration process

Use DBD’s current online-services entry point and Biz Regist instructions for the applicable entity. Confirm the live checklist, identity verification, signing and foreign-document requirements. Older e-Registration walkthroughs and pre-amendment company templates may no longer fit.

Review the name, objectives, address, capital, genuine participants, directors or managers and signing conditions before submission. Check the registered outcome and keep the official documents, receipt, constitutional records and access. Registration is a milestone in the launch, not proof that every operational step is complete.

6. Arrange banking, capital and cash controls

Ask the chosen bank for its current business-account requirements and authority process. Document capital and any loans properly, retain remittance evidence and distinguish funding from sales. For cross-border funds, confirm supporting documents and exchange-control requirements with the authorised bank.

Set approval limits and separate preparation from payment release where practical. Establish who can add beneficiaries, change account details and recover access. Keep a cash forecast that includes deposits, equipment, stock, payroll, compliance and a delayed opening.

7. Set up tax, bookkeeping and invoicing

Confirm taxpayer and VAT registrations, payment-specific withholding, invoicing and source-document requirements. Do not charge VAT or issue VAT tax invoices merely because the business has incorporated. Have unusual supplier and overseas payments reviewed before money moves.

Appoint suitable accounting support, set the accounting period and monthly close, and plan audit and annual filings. Keep company access to the ledger, documents and accepted government submissions. Agree the provider’s scope and handover before the first busy month.

8. Prepare employment and individual work rights

Agree employment terms, pay, working time, leave, policies and payroll controls. Review social-security coverage and the employer and employee registration process. Confirm safety and any qualified-person requirement for the operation.

For foreign staff and working founders, settle the appropriate immigration and work route, employer and role before duties begin. A shareholder position, director appointment or business visa is not a universal work authorisation. Build document preparation and lawful start conditions into the hiring timetable.

9. Make the customer-facing operation ready

Review contracts, terms, price and tax presentation, refunds, warranties, complaints and any required disclosures. Check the rights to the brand, website, photographs, software and other material. Protect original work before launch or technical disclosure where appropriate.

Map personal data from customers, staff and suppliers. Implement the relevant notices, lawful-use assessment, access, security, processor arrangements, retention and incident response. A copied privacy notice will not describe an operation that collects different information or shares it with different providers.

10. Open only when the essential gates are complete

Run a documented readiness review of the entity, premises, permissions, people, banking, tax, systems, insurance and delivery process. Identify unresolved items and whether they prevent a lawful or reliable opening. A marketing date should not override a required approval.

Start with an operating scope the business can deliver and is permitted to undertake. Keep the approved version visible to staff. Monitor early customer feedback, cash, quality, collections and workload, then make controlled changes based on evidence.

11. Assign the recurring work before launch

Create a calendar for accounts, tax, payroll, contributions, meetings, statutory records, renewals and event-driven changes. Give each duty an owner, reviewer, date rule and official proof location. Treat a new site, activity, owner, director or foreign employee change as a trigger for review.

For an ordinary private company, annual-statement approval, DBD submission, the shareholder-list copy and corporate tax returns have different timetables. Do not reduce them to one “annual filing.” Review obligations even during a low-sales or dormant period, or complete a proper closure if the business stops.

Common questions

How long does setup take?

It depends on the entity, activity, foreign documents, premises, bank and approvals. Use a dependency-based schedule rather than one promised incorporation-to-opening timeframe.

What is the universal setup cost?

There is none. Separate official fees, professional work, capital, deposits, equipment and operating cash, and obtain current quotes for the actual project.

Can incorporation and permission to trade be completed separately?

Yes, they address different requirements. Track each stage and do not begin an activity that requires prior permission until that permission is in place.
