Company & Licensing — End-to-End
What company services do foreign owners need in Thailand?
Most need company registration, a tax ID and VAT registration, monthly tax filings, annual audited accounts and, for foreign staff, work permits and visas. Foreign shareholding is limited in many business types. Check current rules with the Department of Business Development and the Revenue Department.

Thai company formation · BOI · FBL · VAT / Tax ID · Trademark Madrid Protocol · PDPA compliance — with lawyers and CPAs under one roof.
Quick Answer
Formation: Company setup 7–10 days + VAT/bank account
License: BOI 4–6 months (100% foreign) · FBL 3–4 months
IP & Compliance: Trademark 14–18 months · Copyright 60 days · PDPA audit 6–8 weeks
Before reserving a name, agree activities, genuine shareholders, capital and signing powers. Check premises use and sector permits, then prepare formation records and file with DBD. Incorporation does not automatically deliver VAT status, a bank account, a visa or a work permit. Assess each separately; approval and completion dates are not guaranteed.
Start with actual operations, customers, processes, technology, staffing and investment, then match current activity criteria. Prepare a plan and evidence addressing those criteria; a fixed business-plan page count cannot establish eligibility. Foreign ownership, tax, machinery and expert privileges depend on the project and conditions. No outcome or unlimited foreign-worker quota is promised.
List actual activities and revenue streams before choosing the route. A licence applies where the activity and law allow it; a certificate may apply to qualifying treaty or promoted entitlements. Do not label every Amity case an FBL or assume one BOI project covers all company activities. Obtain necessary operating rights before starting; approval is not guaranteed.
Separate tax-identification checks, VAT assessment and filing, and bank-account preparation. Review premises and activities first. VAT registrants must maintain invoices and returns as applicable, including months without sales. Banking, refunds and e-Tax access are not automatic.
Start with ownership, the mark actually used and goods or services. Search word and device elements before selecting classes. For Madrid, assess the basic filing, target territories and dependency risks. Clearance is not an approval guarantee; examiner responses and opposition work require separate scope review.
Collect creation records, dates, versions and contracts before notification. Copyright protects qualifying expression, not every idea. Ownership of employed or commissioned work depends on law and agreements; “work-for-hire” is not a universal answer. Notification does not guarantee litigation success.
Map customer, employee, system and vendor data before prioritising risks. Assess a legal basis for each purpose rather than requiring consent everywhere. Review processing records, processor agreements, overseas transfers and breach response. A review identifies gaps and remediation; it is not immunity certification.
FAQ
- Company registration vs BOI vs FBL — what's the difference?
- Company registration is the baseline (DBD, 7–10 days). BOI grants tax + visa privileges (4–6 months). FBL permits foreigners in restricted List 3 activities. Many firms hold BOI + FBL together.
- When can foreigners own 100%?
- Three routes: (1) BOI-promoted activities, (2) FBL List 3, (3) US–Thai Amity Treaty for Americans. Otherwise a 51% Thai partner is required.
- Is PDPA compliance mandatory for small startups?
- Fees depend on the documents, destination and urgency. Send your documents for a written quote after review — no prices are published. Any government or embassy fees are set by the authority; verify them directly before filing.
- Trademark vs copyright — what's the difference?
- TM protects names/logos on goods/services (10 years, renewable). Copyright protects creative works automatically (life + 50 years). Most businesses need both.

Frequently asked questions
- Can a foreigner own 100% of a Thai company?
- Full foreign ownership is possible for some activities, but there is no blanket permission. Check the Foreign Business Act definition, actual activities, sector-specific restrictions and any required licence or certificate. BOI promotion and treaty rights apply only within their approved scope; they do not automatically confer land rights, visas or work permits. Do not use nominee shareholders. Verify the proposed structure with DBD.
- What is the minimum registered capital for a Thai company?
- Do not apply one capital figure to every incorporation, foreign-business licence, visa or work-permit application. Registered capital and paid-up capital are different, and the applicable requirements depend on actual activities, ownership, permit category and any BOI or treaty conditions. Capital is a company funding requirement, not our service fee. Confirm the relevant criteria with DBD, the Department of Employment and Immigration before choosing the structure. Ask our team for a quotation for the agreed work.
- How long does company registration take?
- Separate document preparation, name reservation, signatures and DBD review from VAT registration, Social Security and bank onboarding. Timing depends on the filing channel, complete documents and any requests for corrections or additional evidence; no completion date is guaranteed. Ask our team for a quotation and a planning estimate after the proposed structure and documents have been reviewed.
- What ongoing accounting obligations does a Thai company have?
- A Thai limited company keeps statutory books and prepares audited annual statements even without trading. Tax returns depend on its payments, VAT status, accounting period and taxpayer category: PND1, PND3 and PND53 are not universal monthly returns for every company, and PP30 applies to VAT-registered businesses, including nil-return months while registration remains active. Check PND50, PND51 and each filing deadline with RD; check annual statements and shareholder filings separately with DBD.
