Private advisory service — not a government website. UnionSPACE is a private business consultancy and commercial services provider. We are not part of, affiliated with, or endorsed by Thailand's Department of Business Development (DBD), Board of Investment (BOI), Revenue Department, Social Security Office, Ministry of Commerce or any Thai government authority. Government registrations, licences, certificates, tax registrations and approvals are issued or controlled by the relevant authorities.
Planning a Thai Company? Choose the Ownership Route Before You File.
Thailand company formation is not only a DBD registration exercise. Foreign ownership, business activity, registered capital, office suitability, tax registrations, banking and sector licences need to work together before the structure is finalized.
Start with a Thailand Company Fit Review: tell us what the business will do, who will own it, where it will operate and whether you need visas, work permits, BOI, FBL/FBC, Treaty of Amity, VAT or regulated-business licences.

Commercial advisory and coordination. Government authorities retain control of official registrations and approvals.
The business activity and lawful ownership route are reviewed before a structure is recommended.
DBD, BOI, Revenue Department, banks and licensing authorities make independent decisions.
WHY REVIEW FIRST
A Thai Company Is More Than a DBD Certificate
The commercial question is not simply whether a company can be registered. It is whether the ownership, activities, capital, office, tax position and licences support what the business actually intends to do.
1. Activity & Foreign Business Act Review
Map the proposed revenue-generating activities before choosing shareholders. Restricted activities can require a lawful exemption, licence or certificate.
2. Ownership & Investor Structure
Assess genuine Thai-majority ownership, majority or full foreign ownership, BOI, FBL/FBC or Treaty of Amity routes where applicable.
3. Office, Capital & Operating Footprint
Check whether the proposed office and capital can support DBD, VAT, Social Security, immigration, licensing and inspection requirements.
4. Licence-to-Operate Roadmap
Identify what may be needed after incorporation, including tax registrations, bank onboarding, BOI/FBA permissions and sector-specific licences.
CLEAR RESPONSIBILITIES
What Thai Authorities Do — and What UnionSPACE Does
UnionSPACE provides private professional support. Thai authorities, banks and licensing bodies remain responsible for official systems, registrations and approvals.
- Set company, foreign-business, tax, labour and sector requirements.
- Operate official registration and tax systems.
- Issue or control DBD registrations, BOI promotion, FBL/FBC, VAT registrations and sector licences.
- Determine whether filings are accepted, queried, approved or rejected.
- Banks separately decide KYC and corporate-account applications.
- Explain market-entry and ownership considerations relevant to your proposed business.
- Review activities, ownership, capital, office and operating assumptions.
- Prepare a practical company-setup and compliance roadmap.
- Coordinate documents, local professionals and commercial support within the agreed scope.
- Provide office, accounting, tax, HR, banking-readiness and ongoing business support where applicable.
Prefer to use official Thai government channels directly?
Businesses can use official Thai government information and filing channels directly where eligible. Government fees may be lower than private professional-service fees.
Useful official starting points include the Department of Business Development, Thailand Board of Investment, and Revenue Department. UnionSPACE's fees are for private advisory and commercial support and are separate from government charges unless expressly stated in a written proposal.
FOREIGN OWNERSHIP
Choose a Lawful Thailand Company Structure
Thailand does not impose one ownership formula on every business. The correct route depends on the activity, investor nationality, capital, licences and commercial plan.
Genuine Thai-Majority Company
A Thai-majority structure may operate activities that would otherwise be restricted to a foreign company. Thai shareholders must be genuine investors using their own funds and exercising real shareholder rights. Nominee arrangements are prohibited.
Foreign-Owned Company
Full or majority foreign ownership may be available where the activity is not restricted, falls within an exemption, or qualifies for a Foreign Business License or Foreign Business Certificate.
BOI or Treaty Route
Eligible projects may seek BOI promotion and related foreign-business permissions. Qualifying US investors may consider the US–Thailand Treaty of Amity, subject to exclusions and certification requirements.
HOW WE WORK
Structure First. Then Register and Activate.
A consultation-first process reduces the risk of registering a company that cannot operate the intended activity, use the intended office, obtain the required tax status or support the planned immigration/licensing route.
1. Structure & Fit Review
Confirm the business activity, ownership route, registered office, capital, directors, hiring plan and any BOI/FBA/licensing needs.
2. Prepare & Coordinate DBD Filing
Prepare the name, memorandum, articles, shareholder/director information, applications and signing pack for the agreed filing route.
3. Activate Tax & Compliance
Set up bookkeeping, tax, VAT where applicable, electronic filing, payroll and employer Social Security, plus annual audit and DBD compliance planning.
4. Banking & Ongoing Support
Prepare the corporate-account dossier and coordinate introductions. The bank independently controls KYC, attendance requirements and approval.
INVESTOR FIT
When a Thai Limited Company Usually Deserves Serious Consideration
Often Relevant When You Plan To
- Build a long-term operating presence in Thailand.
- Hire employees, lease premises or invoice Thai customers locally.
- Obtain VAT, Social Security, licences, visas or work permits.
- Use a lawful foreign-ownership route such as BOI, FBL/FBC or Treaty of Amity where applicable.
Review the Structure Carefully When
- The activity may be restricted under the Foreign Business Act.
- The project needs FDA, factory, tourism, telecom, education, import-control or professional licences.
- You are considering Thai shareholders primarily to avoid foreign-business restrictions.
- You need the company to support immigration, work permits or BOI privileges.
PRIVATE CASE REVIEW & PLANNING
Start With a Written Thailand Setup Recommendation Before You Commit to Implementation
Before committing to incorporation, shareholders, an office, VAT registration, a foreign-ownership route or banking, we first review the actual business and map the most suitable lawful Thailand setup strategy.
Thailand Private Case Review & Planning
This is a paid private advisory engagement with UnionSPACE. It is not a government fee, filing fee, licence fee, tax payment, immigration fee or bank charge, and it does not purchase or guarantee any government, authority or bank approval.
Advisory fee for the case review, planning analysis and written recommendation report.
- Detailed situation review: understand the proposed activity, investor nationalities, intended ownership, capital, location, hiring plan, licensing needs, VAT requirements and expected banking transactions.
- Practical ability & eligibility review: assess Foreign Business Act exposure and whether a genuine Thai-majority structure, non-restricted foreign ownership, BOI, FBL/FBC, Treaty of Amity or another lawful route may be relevant.
- Objective mapping: identify what the company must be able to do commercially, where it will operate, who it will hire, what licences it needs and how the owners expect to fund and control it.
- Route comparison: compare the most relevant ownership and licensing approaches and highlight capital, office, tax, work-permit, sector-licence and banking dependencies.
- Written recommendation report: provide UnionSPACE's recommended way forward, suggested ownership/licensing route, implementation sequence, key assumptions and issues to confirm before proceeding.
THB 20,000 can be credited if you proceed with UnionSPACE
If you proceed with UnionSPACE for the recommended implementation, the THB 20,000 case-review fee can be applied as a credit against UnionSPACE's own professional service fees. The credit does not apply to government, BOI, licensing, tax, immigration, banking, workspace or other third-party charges unless expressly agreed in writing.
UnionSPACE is a private advisory provider. This review is intended to help the client make an informed commercial decision before engaging implementation services. Government authorities, regulators and financial institutions independently determine registration, licensing, tax, immigration and bank-account outcomes.
