Can a foreigner own 100% of a Thai company?

Only through specific routes: a BOI (Board of Investment) promoted company for eligible activities, a US Treaty of Amity company for US nationals, an IBC (International Business Centre) for qualifying head-office activities, or by operating under a Foreign Business License. The default Thai Limited Company caps foreign ownership at 49%; the remaining 51% must be Thai-held.

What is the LTR Visa and does it help founders?

The Long-Term Resident (LTR) Visa, launched 2022, gives 10-year multi-entry residency, a flat 17% personal income tax on Thai-sourced professional income (for the WGTP category), no 90-day reporting, and a digital work permit. The most relevant category for founders is Work-From-Thailand Professional (WGTP) for employees of foreign companies, or Highly-Skilled Professionals for those joining a Thai company in a target industry.

What does it cost to set up a Thai Limited Company?

Registration: THB 5,500–7,000 government fees plus THB 25,000–60,000 legal fees. Minimum registered capital: THB 2 million per foreign work permit you want to issue. Realistic first-year operating cost (office, accountant, audit, social fund): THB 200,000–400,000 (~$5,500–$11,000).

Bangkok, Chiang Mai, or Koh Samui?

Bangkok is where the lawyers, banks, BOI office, and international corporates are — non-optional if you need BOI promotion or large enterprise clients. Chiang Mai is the historical digital-nomad hub but has cooled. Koh Samui has quietly become the operator base of choice for remote founders running global ventures: international airport, Strata House and similar high-end coworking, predictable visa runs to Singapore, and meaningfully lower burn than Bangkok.

How does Thai tax work for a foreign founder?

Thai-source income is taxed in Thailand regardless of residency. Tax residents (180+ days/year) are also taxed on foreign-source income remitted to Thailand in the same calendar year earned — a rule that tightened in 2024 to include income earned in prior years if brought into Thailand. Corporate tax is 20% standard, with reduced rates of 0–15% for SMEs on the first THB 3M of profit. BOI-promoted companies can get up to 8 years corporate tax exemption.

Do I need a Thai partner I can trust?

For a standard 49/51 Thai Limited, yes — and 'trust' has to be backed by a properly drafted preferred-share structure or voting agreement so the 51% Thai shareholders cannot vote you out of your own company. This is the single highest-risk part of the non-BOI route. If your activity qualifies for BOI promotion, take BOI — it removes this problem entirely.

How to Start a Business in Thailand as a Foreigner (2026)

Thailand rewards founders who pick the right structure on day one and punishes ones who copy a generic LLC playbook from another country. Foreign ownership rules, capital and work-permit requirements, and recent changes to how foreign income is taxed when remitted into Thailand all matter from the first decision. Figures below are orientation ranges drawn from public sources at time of writing — confirm current numbers with a licensed Thai lawyer and accountant before you act.

Five legal routes — pick before you pay anyone

Thai Limited Company (49/51). Default. Cheap. Foreign-owned up to 49%; the 51% must be genuinely Thai. Workable, but you must structure preferred shares / voting properly. Do not skip this.
BOI-promoted company. 100% foreign ownership, work permits without the 4-Thai-employees rule, land ownership rights, tax holidays up to 8 years. Activity must be on the BOI list — software, R&D, digital services, manufacturing, regional HQ all qualify. Application takes 60–90 days.
US Treaty of Amity company. US nationals only. 100% foreign ownership in most service sectors. Faster than BOI, no tax benefits.
IBC — International Business Centre. For regional HQ, treasury, international trading. Requires THB 10M minimum capital and qualifying activity. Tax rate 3–8% on qualifying income.
Representative Office. Non-revenue activity only — sourcing, market research, quality control. Cannot invoice. Cheap to maintain.

Visa: LTR is the founder's quiet win

The Long-Term Resident (LTR) Visa launched in 2022 and is still under-used. For most location-independent founders the relevant category is Work-From-Thailand Professional (WGTP): 10-year visa, flat 17% tax on Thai-sourced professional income, multi-entry, no 90-day reporting, digital work permit, dependents included. Eligibility requires $80k/year personal income (or $40k with a master's degree or relevant senior role).

For founders incorporating in Thailand: Highly-Skilled Professional category if you join a Thai company in a target industry, or the standard Non-B + work permit route through your BOI or Thai Limited.

Banking, accounting, and the things that surprise people

Corporate banking takes 2–6 weeks. Bangkok Bank and Kasikorn are the founder defaults. Expect 2 in-person visits and a request to maintain a minimum balance (~THB 50k–200k).
Every Thai company must file monthly VAT (if registered), monthly withholding tax, bi-annual corporate tax, and undergo an annual audit by a licensed Thai auditor. Budget THB 8,000–25,000/month for accounting + THB 25,000–50,000 for the annual audit.
Work permit rules: standard Thai Limited needs THB 2M registered capital per foreign work permit, plus 4 Thai employees per foreigner. BOI waives both.
The 2024 Revenue Department reinterpretation of Section 41: foreign-source income remitted into Thailand by a tax resident is generally treated as assessable in the year it is brought in, regardless of when it was earned. Treatment of specific situations (timing, double-tax treaties, LTR exemptions) varies — get a written opinion from a Thai tax advisor before relying on any "remit later" strategy.

Why Koh Samui is becoming the operator base

Bangkok is still where the legal, banking, and corporate work happens. But for the actual day-to-day of running a global venture, an increasing share of founders are basing themselves on Koh Samui: international airport, fibre internet at coworking-grade spaces (Strata House, KoHub, Yogyam), restaurants and gyms that match Lisbon or Bali, and a real founder community that does not exist in the same density elsewhere on the islands. Burn for a single founder runs 30–50% lower than Bangkok and the visa run to Singapore is a 90-minute flight.

RFUD is based at Strata House, Patra Building, on Koh Samui — this is the playbook we run with every founder who lands here asking how to set up properly.

What RFUD does with this

We help founders sequence the structure correctly: which entity to open, in which order, and how to pair a Thai operating layer with a Wyoming or Singapore holding company so the IP, banking, and contracting all live in the right place. Open the RFUD Launch Assistant to map your specific situation — jurisdiction, visa, capital, and where your customers will be.
