Good to know
Good to Know
- There's no separate 'Koh Phangan' business registry — incorporation happens through Thailand's national DBD system, so the paperwork and rules are identical whether your office is in Bangkok or on the island.
- The much-advertised 'register a 100%-foreign-owned Thai company easily' services usually mean setting the company up as majority-Thai-owned (with a nominee) and transferring control afterward — this is explicitly illegal under the Foreign Business Act and carries real risk of future investigation, fines, and forced dissolution, even if the initial registration goes through smoothly.
- If your plan includes sponsoring your own or an employee's work permit, budget for the 2,000,000 THB paid-up capital requirement per foreign work permit — this catches a lot of first-time founders off guard since it's separate from setup/service fees.
- As of January 2026, all private limited company registrations must go through the DBD's online 'Biz Regist' platform — paper filing and walk-in counters are no longer accepted, which foreign founders should account for when planning document signing logistics.
- For almost all foreigners other than US citizens using the Treaty of Amity, sole proprietorship isn't a legal option here — a Thai limited company is effectively the only route to formally own a business, which changes both the tax filing burden and the compliance cost compared to freelancing informally.
- A Thai limited company's compliance load is materially heavier than personal freelance filing: expect mandatory monthly bookkeeping, an annual CPA audit, and two Revenue Department filings a year (PND 50 and PND 51), not just a single annual return.
- Using a Thai 'nominee' shareholder just to get around the 49% foreign-ownership cap is illegal and under increased enforcement — this is a common scam/compliance trap for foreign small-business owners setting up on Thai islands.
- The 7% VAT rate is a temporary reduction from the statutory 10% rate, currently extended by decree; budget for the possibility it could revert upward in the future.
Filing Obligations
- Other Taxes
- Specific Business Tax (SBT) applies instead of VAT to certain exempt sectors like banking/finance/insurance, and a Specific Business Tax surcharge and various withholding taxes on dividends, interest, royalties and service fees may also apply depending on structure and treaty relief.
- Annual Return
- Corporations must file annual returns (Form PND 50 / CIT 50) within 150 days of the close of their accounting period.
- Audit Requirement
- A limited company also carries mandatory annual bookkeeping, a statutory CPA audit, filing of financial statements with the Department of Business Development (DBD), and an Annual General Meeting — obligations a sole proprietorship does not have.
- Half Year Prepayment
- A half-year estimate and prepayment return (Form PND 51 / CIT 51) is due within two months after the first six months of the accounting period, with companies required to estimate their annual net profit and pay half of the estimated tax; the prepaid amount is creditable against the final annual liability.
VAT
- Standard Rate Percent
- 7
- Registration Threshold
- THB 1,800,000
- Note
- The standard VAT rate is currently 7% (a reduced rate extended by decree), with registration required once annual turnover crosses the threshold; exports are zero-rated and certain basic goods/services are exempt.
Corporate Income Tax
- Standard Rate Note
- Companies in Thailand must pay Corporate Income Tax (CIT), which ranges from 0% to 20% based on net profits, with larger companies generally facing a flat 20% rate.
- Standard Rate Percent
- 20
- Worldwide Vs Local Income
- A Thai-incorporated limited company (the standard vehicle for a foreign-owned business, since sole proprietorships are generally closed to non-US-citizen foreigners) is taxed on its worldwide net profit, whereas a foreign company without Thai incorporation that merely carries on business or derives income here is generally taxed only on Thai-sourced income, sometimes via final withholding tax rather than a net-profit assessment.

- Max Paid Up Capital
- THB 5,000,000
- Note
- To qualify for the reduced SME rate structure, a company must generally meet statutory conditions, including paid-up capital not exceeding a threshold and annual revenue not exceeding a threshold.
Freelancer Sole Proprietor Vs Company
- Sole Proprietor VAT
- A sole proprietor must still register for and charge VAT once annual income exceeds the VAT threshold, using Form VAT 01 at the local district/sub-district tax office.
- Sole Proprietor Tax Treatment
- Where it is available (Thai nationals, Amity-treaty Americans, or informally via a Thai spouse's name), a sole proprietor pays personal income tax on business profits using their personal tax number rather than filing separate corporate returns, with progressive personal rates from 0% up to 35%.
- Limited Company Ownership Rule
- Foreign ownership above 49% of a Thai limited company generally requires one of a small number of legal pathways (majority Thai shareholding, BOI promotion, a Foreign Business Licence, or Treaty of Amity status for qualifying Americans); using Thai 'nominee' shareholders to fake compliance is illegal, and enforcement of nominee-shareholder crackdowns has intensified in recent years.
- Limited Company Reality For Foreigners
- For nearly all foreigners on Koh Phangan (i.e., everyone except Amity-treaty Americans), the private limited company is the standard and practically only legal route to own and operate a business, since it is the structure that provides liability protection, work-permit eligibility, and credibility with Thai banks and landlords.
- Sole Proprietorship Reality For Foreigners
- In practice, sole proprietorships in Thailand are generally restricted to Thai nationals; the only notable exception is U.S. citizens operating under the US-Thailand Treaty of Amity, who may register a sole proprietorship in most industries. All other foreign nationals cannot legally register a business in their own name as a sole trader.
- Work Permit Capital Note
- Businesses that need to sponsor a foreigner's own work permit through the company are commonly cited as needing a registered paid-up capital in the region of a higher minimum (often cited around 2 million baht per foreign work-permit holder), separate from the general company minimum capital rules.
Limited Company Compliance Cost
- Note
- A limited company's heavier obligations — monthly bookkeeping, monthly tax filings, mandatory annual CPA audit, DBD financial statement filing, PND 50/51 corporate returns, an AGM, and social security contributions for staff — carry a real administrative cost compared to informal freelancing.
Annual Compliance Cost Range

Local Partner Sponsor Requirement
- General Rule
- Foreigners can legally register a 100%-foreign-owned company in Thailand with no Thai partner at all, but the Foreign Business Act (FBA) restricts which business activities a majority-foreign-owned company may actually operate in — most everyday service businesses fall under FBA "List 3", which foreigners are not permitted to run without a license.
- Nominee Warning
- Using a Thai national purely as a nominee shareholder (someone who holds shares but did not invest genuine capital and has no real stake) to disguise foreign control is illegal under the FBA, and 2025–2026 reforms have tightened enforcement, now requiring Thai shareholders to prove financial capacity to invest via bank statements and tax documents. Violations carry criminal penalties, fines, and forced company dissolution.
- Practical Workaround
- Because of this, the most common structure foreigners actually use in practice is a joint venture where Thai shareholders hold at least 51% of the company, making it legally a "Thai company" not subject to FBA restrictions.
100 Percent Foreign Ownership Routes
- Board of Investment (BOI) promotion for eligible sectors (tech, digital, advanced manufacturing, green economy, medical/wellness, creative industries) — grants up to 100% foreign ownership plus tax incentives.
- Foreign Business License (FBL) from the DBD/Foreign Business Committee — case-by-case approval, generally requires 3,000,000 THB minimum capital for the restricted activity.
- US–Thailand Treaty of Amity (US nationals only) — allows majority or full ownership without an FBL for most sectors except communications, transport, and a few others.
Double Tax Agreements
Thailand has signed Double Taxation Agreements with a large number of countries, which prevent income earned by a foreign owner's home-country business from being taxed twice by defining which country has taxing rights — relevant when structuring dividend repatriation or cross-border invoicing from a Koh Phangan-based company.
Informal Freelancing Caveat
Many foreigners on Koh Phangan invoice overseas clients informally without any Thai registration; this sits in a legal grey area since a work permit is technically required to work in Thailand (including remote freelance work performed while physically on the island), and this call does not cover personal tax residency, which is addressed separately.
Minimum Capital
- Restricted Activity With Fbl
- THB 3,000,000
- Per Foreign Work Permit Sponsored
- THB 2,000,000
- Standard Foreign Majority Company
- THB 2,000,000
- Note
- A company can technically register with far less capital, but 2,000,000 THB fully paid-up is the practical threshold needed to sponsor one work permit for a foreign employee; each additional foreign work permit generally requires another 2,000,000 THB, up to a cap around 10,000,000 THB for five foreign staff.
Jurisdiction Note
Company incorporation is governed entirely by Thai national law (Civil and Commercial Code, Foreign Business Act B.E. 2542) and administered by the Department of Business Development (DBD) under the Ministry of Commerce. There is no Koh Phangan-specific or Surat Thani-specific incorporation process — a business on the island follows the exact same national registration system as anywhere else in Thailand.
Common Entity Type
The private limited company (Co., Ltd.) is by far the most common vehicle foreigners use to start a business in Thailand, offering limited liability and the ability to operate like a Thai-owned company once structured correctly.
Realistic Timeline
- With Boi Promotion
- BOI application review typically takes about 3–6 months and generally happens before/alongside incorporation.
- Work Permits And Visas
- Add roughly 2–4 weeks after company registration is complete.
- With Foreign Business License
- Add roughly 3–6 months on top of standard incorporation.
- Standard Private Limited Company
- Roughly 2–4 weeks total from name reservation to registration certificate (core DBD filing/approval itself can be as fast as 1–3 days once all documents are signed and shareholders/directors are physically present; the rest of the time is document prep, translation, and bank account setup).
Incorporation Steps
Incorporation Steps
- 1. Reserve a unique company name with the DBD (now done via the DBD Biz Regist online platform, the sole legal channel for private limited company registration since January 2026).
- 2. Prepare and file the Memorandum of Association (MOA), listing company objectives, registered capital, and initial shareholders.
- 3. Convene a statutory meeting to adopt Articles of Association, appoint directors, and formally allocate shares.
- 4. Submit the full registration package (MOA, Articles of Association, shareholder list, director list, registered address proof) to the DBD to obtain the company registration certificate and 13-digit company/tax ID number.
- 5. Register for a corporate tax ID with the Revenue Department, and for VAT if annual turnover will exceed 1,800,000 THB or if sponsoring foreign staff.
- 6. Open a corporate bank account (typically requires in-person presence of directors/shareholders in Thailand).
- 7. If applicable: apply separately for a Foreign Business License, BOI promotion, or specific sector licenses (e.g. food/FDA, tourism, alcohol) before commencing regulated activities.
- 8. If hiring foreign staff: apply for Non-Immigrant B visas and work permits, and register with the Social Security Office within 30 days of the first hire.
Director Requirements
There is no legal requirement for a company director to be a Thai citizen — foreigners can serve as sole director and shareholder. However, a foreign director who wants to actively work in/manage the company in Thailand needs a Non-Immigrant B visa and a work permit.

Registered Office Requirement
Every company needs a registered Thai address (residential or commercial) for DBD filings; a virtual office is generally accepted for initial registration, but VAT registration or an FBL application requires an inspectable physical commercial space.
