Most Phuket founders arrive thinking they need a standard Thai limited company — 51% Thai shareholding, the foreign half running the operation through preferred shares and side letters. That structure works for restaurants and dive shops. It is the wrong answer for software, content, design and most service businesses that match a BOI category.
A BOI-promoted company gives you 100% foreign ownership, work permits without the standard 4-Thai-to-1-foreign employee ratio, an 8-year corporate tax holiday in some categories, and access to Smart Visa for the founder and key staff. The trade is a more demanding application, slightly higher ongoing compliance, and an obligation to actually do the activity you applied under.
Here is what the BOI process actually looks like in 2026 when you are running it from Rawai, Cherng Talay or a serviced office in Phuket Town — including the categories that approve quickly, the categories that get rejected, and the timeline you should actually plan around.
BOI company from Phuket — the 60-second version
- Best categories for solo founders 2026: 5.7 Software, 5.10 Digital Content, 5.11 E-commerce, 5.6 Digital Services, 5.4 Engineering Design.
- Registered capital: typically 1 million THB minimum; 2–3 million THB if founder needs a work permit (one foreign WP per 2 million paid-up capital under BOI).
- Setup cost all-in: 80,000–180,000 THB legal + government for a solo software/digital company; 60,000–150,000 THB annual ongoing.
- Timeline: 4–8 weeks BOI promotion + 2–4 weeks DBD registration + 2–6 weeks first work permit. Plan for 3–5 months total.
- Tax incentive: 5- or 8-year corporate income tax holiday on promoted activity income, plus import duty exemptions.
- Smart Visa pathway: available to BOI-promoted company employees and founders meeting category-specific criteria (typically minimum 100,000 THB monthly salary).
- Phuket-friendly: registered office can be a Bang Tao, Cherng Talay or Phuket Town address; BOI office in Bangkok handles application regardless of operating location.
What BOI promotion actually gives a Phuket founder
The Board of Investment is Thailand's investment promotion agency, sitting under the Office of the Prime Minister. It promotes specific business categories with a layered package of incentives. For a foreign founder, the relevant ones are:
100% foreign shareholding. Outside BOI, most Thai operating companies are capped at 49% foreign ownership under the Foreign Business Act. A BOI promotion explicitly waives this for the promoted activity. You can own the whole company and the whole share class.
Work permits without the 4:1 rule. A standard Thai company needs four Thai employees to support one foreign work permit. BOI companies are exempt — instead the rule is one foreign WP per 2 million THB of paid-up capital, with reasonable expansion possible. For a solo founder this is the difference between hiring four Thai staff before you can work for yourself and actually working from day one.
Corporate income tax holiday. Depending on category and conditions, BOI promotions include a 3-year, 5-year or 8-year exemption from corporate income tax on income from the promoted activity. The standard CIT rate in Thailand is 20%, so on a profitable promoted business this is meaningful.
Import duty exemptions on machinery and raw materials used in the promoted activity. Less relevant to most digital founders, very relevant to manufacturing and marine industries.
Smart Visa pathway. BOI-promoted companies can sponsor Smart Visa applications for their team. Smart Visa T (Talent) gives 4 years validity, no 90-day reporting, work permit included, dependents allowed. A meaningful upgrade from standard non-B work permit life.
Easier land ownership for the promoted entity. A BOI company can in some categories own land for its promoted operations. This rarely matters for digital businesses but matters for industrial or marine companies.
BOI categories that work for Phuket founders
The BOI updates its category list periodically. As of May 2026, these are the categories I see Phuket founders applying under successfully.
5.7 Software development
The cleanest category for solo and small-team Phuket founders. Covers software development, software publishing, mobile apps, embedded software, AI/ML applications and enterprise software. Standard incentive package: 8 years corporate income tax exemption capped at 100% of investment. Approvals are typically clean if your business plan reads as actual software work — code committed, products shipped, clients invoiced. Approvals slow down if the business plan reads as a marketing front for offshore freelance work.
5.10 Digital content production
Covers animation, computer-generated imagery, e-publishing, e-learning, video game development and digital media production. Good fit for the Phuket creator economy — production studios, animation shops, video game studios. The trick is to actually have production output, not just a YouTube channel.
5.11 E-commerce platform
Pure-play e-commerce companies (running your own platform or operating significant online retail) qualify here. Drop-shipping operations and affiliate marketing businesses usually do not — the BOI wants substantive platform development or genuine inventory operations.
5.6 Digital services
A broader category covering cloud services, data centres, cybersecurity services, IoT services and digital transformation consulting. Useful when your activity does not neatly fit 5.7 software or 5.10 content but is clearly digital. Approval is slower than 5.7 because the category is broader and reviewers ask more questions.
5.4 Engineering design
Engineering design services including marine engineering, mechanical, electrical and structural design. Phuket has a real cluster of marine industry consultants serving the Phuket Yacht Haven and Boat Lagoon ecosystems — this category fits them well.
3.2 Marine industry services
Specifically supports Phuket's yacht and marine sector — yacht broking, marine maintenance, marine equipment trading. Founders running businesses out of Boat Lagoon (Koh Kaew), Yacht Haven (Mai Khao) or Royal Phuket Marina sometimes find this fits better than a generic services category.
7.13 International Business Centre (IBC)
For multinational structures running regional headquarters or shared services from Thailand. Higher capital threshold (10 million THB paid-up) and requires substantive operations but the incentives are strong. Some Phuket founders use IBC structures when their business serves multiple jurisdictions through a single Thai entity.
The application process step by step
The realistic flow for a Phuket-based founder, May 2026:
- Categorisation analysis (week 1). Sit with a corporate lawyer who has BOI submission experience. Argue out which category fits your real business model and what the registered capital should be. Avoid the temptation to chase the category with the headline incentives — pick the one that genuinely matches.
- Business plan and financial projections (weeks 1–3). The BOI wants a substantive plan — typically 25–40 pages — covering business model, market analysis, three-year financial projections, employment plan (Thai vs foreign), technology stack, intellectual property. This is the part founders underestimate. The BOI reviewers actually read these.
- Submission to BOI (week 3 or 4). Filed at the BOI office in Chamchuri Square in central Bangkok. Some submissions can be done online via the BOI e-Investment Promotion system; many founders still submit physical files via their lawyer.
- BOI review and Q&A (weeks 4–8). Reviewers may come back with questions, requests for further detail, or amendments to the application. Respond promptly. Plan to be available for an interview if asked — most digital category interviews now happen by video call rather than in-person.
- BOI promotion certificate issued (week 6–8 for clean files). You receive a promotion certificate detailing the activity, conditions, and incentive package.
- Company registration at DBD (weeks 8–10). With the BOI certificate, register a Thai limited company at the Department of Business Development. Phuket DBD office is on Wirat Hongyok Rd in Phuket Town. The BOI-promoted designation flows through automatically.
- BOI registration step (post-registration). Submit the registered company documents to the BOI to confirm activation of the promotion.
- Capital injection and FET letter (weeks 10–12). Wire paid-up capital from abroad into the new company's Thai bank account. Bank issues FET. This is the proof of foreign investment that activates BOI privileges.
- Work permits and visas (weeks 12–18). Apply for the founder's non-immigrant B visa or Smart Visa, then work permit at the Department of Employment. With BOI promotion, the WP process is materially faster than standard non-B WP.
Smart Visa: when it makes sense for Phuket founders
Smart Visa is a separate visa category aimed at investors, talent and startup founders in targeted industries. For BOI founders, the most relevant categories are:
Smart T (Talent) — for experts in targeted industries with minimum monthly salary of 100,000 THB. 4-year visa, no 90-day reporting, work permit included, dependents allowed.
Smart E (Executive) — for senior executives in targeted industry companies with minimum monthly salary of 200,000 THB, 5 years of senior management experience and a bachelor's degree.
Smart S (Startup) — for startup founders in targeted industries holding minimum 600,000 THB equivalent in funds plus health insurance.
Whether you need Smart Visa or a standard non-B work permit through your BOI company depends on whether the additional cost and complexity is worth it. For a solo founder who is the sole director and shareholder, a standard BOI work permit is usually simpler. For founders bringing in a senior team or who travel internationally constantly, Smart T removes a lot of friction.
Move paid-up capital to Thailand without losing 2% to your bank
BOI registered capital has to arrive as foreign currency and convert at a Thai bank. Banks typically bake a 1.5–3% margin into the rate. On 2 million THB paid-up capital that is 30,000–60,000 THB you do not need to give away.
Open Wise for the capital transfer →What the BOI application actually costs in 2026
Realistic numbers from recent submissions I have visibility into:
| Cost item | Typical range (THB) | Notes |
|---|---|---|
| Corporate law firm — BOI submission package | 80,000–150,000 | Includes categorisation analysis, business plan drafting support, application filing, Q&A handling |
| BOI application government fee | 0–5,000 | BOI itself is essentially free for application |
| DBD company registration | 15,000–25,000 | Government fees + legal handling for limited company setup |
| Paid-up capital wire (the actual money) | 1,000,000–3,000,000 | This is your investment, not a fee. Sits in the company. |
| FX cost on the capital wire (bank vs Wise) | 10,000–60,000 saved with Wise | Real margin from a bank vs Wise mid-market |
| Work permit application (founder) | 5,000–10,000 | Government fees only; add 10,000–25,000 if you use an agent |
| Smart Visa application (if used) | 10,000 | Per applicant, government fee. Add agent fees if used. |
| Registered office / virtual office (annual) | 15,000–60,000 | Bang Tao co-working with address, Phuket Town serviced office, etc. |
| Accounting + audit (annual) | 60,000–150,000 | BOI companies have additional reporting obligations. Phuket Town accounting firms typically charge less than Bangkok equivalents. |
| BOI compliance + annual report | 15,000–30,000 | Annual report to the BOI on promoted activity progress |
All-in first-year cost for a clean solo software BOI setup in Phuket: roughly 250,000–450,000 THB excluding the paid-up capital itself.
Mistakes Phuket founders make at the BOI stage
The pattern is reliable across founders I have worked with.
Mistake one: picking the category with the best incentives rather than the category that fits the business. The BOI reviewers know the categories inside out and will reject a poorly-fitted application or — worse — approve it and then revoke it 18 months later when annual reporting shows the activity does not match. Pick the right category up front.
Mistake two: thin business plans. Many founders submit a 10-page document that reads like a pitch deck. The BOI wants substantive financial projections, headcount plans, technology details and market analysis. A 30-page plan with realistic numbers gets approved faster than a glossy 15-pager.
Mistake three: underestimating paid-up capital. Setting paid-up capital at the bare minimum 1 million THB triggers a single foreign work permit. Many founders later realise they wanted to hire a foreign CTO or sales lead and have to increase capital, which means more wires, more FET letters, and time lost. Plan headcount up front and size capital accordingly.
Mistake four: registered address shortcuts. A residential condo address used as registered office can cause issues at work permit stage because the Department of Employment wants a commercial-zoned address. Use a proper serviced office, co-working address service or commercial unit from day one.
Mistake five: trying to do everything in English. The BOI accepts English applications but many supporting documents (DBD filings, capital injection paperwork, work permit applications) ultimately route through Thai-language systems. A Thai-fluent corporate lawyer matters.
Phuket-specific operational notes
Running a BOI company from Phuket rather than Bangkok creates a few small frictions you should plan around.
The BOI office is in Bangkok. Most filing now works remotely, but annual progress reports and certain amendments still benefit from an in-person meeting. Budget 2–3 day trips to Bangkok a year for BOI matters. A direct AirAsia or Bangkok Airways flight from HKT to BKK is 1,200–3,000 THB one-way booked a few weeks ahead.
Banking. Bangkok Bank's Phuket Town and Boat Avenue branches handle BOI company account openings competently. Kasikorn's Boat Avenue branch is similarly experienced. Avoid smaller bank branches in Patong or Kata for company account opening — they will route to head office and add weeks.
Hiring Thai staff. The Phuket labour market is thinner than Bangkok for senior digital roles. Mid-level software engineers, designers and content producers are available but the talent pool is meaningfully smaller. Many Phuket-based BOI companies hire remote Thai staff from Bangkok and Chiang Mai, which works fine under BOI rules — the requirement is Thai employment, not physical office presence.
Audit and accounting. Phuket Town has several capable audit firms for BOI companies — the offices around Phang Nga Rd and Yaowarat Rd in particular. Annual audit cost in Phuket runs 30–40% below Bangkok equivalents for the same scope.
