Foreign founders in Thailand often ask the same question: Can I work through my own company, and which visa\/work route fits?<\/em> There is no single \u201cbest\u201d answer. The practical choice usually sits among three paths: (A)<\/strong> self-sponsor a work permit through your own Thai limited company with a Non-Immigrant B stay; (B)<\/strong> structure under \u0e42\u0e1b\u0e23\u0e42\u0e21\u0e0a\u0e31\u0e48\u0e19 BOI<\/strong>; or (C)<\/strong> qualify for the current Smart S<\/strong> startup track under BOI Por. 5\/2568.<\/p>\n

This guide maps who each path fits, the main friction, and where to dig deeper on ThaiLawOnline. It is general information<\/strong>, not a legal opinion for your file. Thai rules and practice change; confirm before you commit capital or start work.<\/p>\n

Who this comparison is for (and who it is not)<\/h2>\n

Lead rule:<\/strong> Owning shares or sitting on a board does \u0e44\u0e21\u0e48<\/strong> by itself authorise work in Thailand. Under the Emergency Decree on Managing the Work of Foreigners B.E. 2560 \u0e2a\u0e48\u0e27\u0e19\u0e17\u0e35\u0e48 8<\/strong>, a foreigner generally must not work without a work permit (or a statutory exemption such as an approved Smart S activity).<\/p>\n

Day-to-day management (signing contracts, directing staff, running operations) is treated as work. Whether purely passive attendance at board meetings requires a permit is fact-specific<\/strong>. Do \u0e44\u0e21\u0e48<\/strong> treat an informal \u201cboard-meeting-only\u201d story as a safe loophole.<\/p>\n

This article is for founders and directors who intend to build or run a Thai company<\/strong> and need a lawful stay-and-work combination. It is \u0e44\u0e21\u0e48<\/strong> aimed at tourists, or at people whose only plan is remote work from Thailand under DTV \/ LTR-style programmes. Those routes differ from founding and working locally; see our \u0e04\u0e39\u0e48\u0e21\u0e37\u0e2d\u0e17\u0e32\u0e07\u0e01\u0e0e\u0e2b\u0e21\u0e32\u0e22\u0e2a\u0e33\u0e2b\u0e23\u0e31\u0e1a\u0e1c\u0e39\u0e49\u0e17\u0e33\u0e07\u0e32\u0e19\u0e2d\u0e34\u0e2a\u0e23\u0e30\u0e17\u0e32\u0e07\u0e14\u0e34\u0e08\u0e34\u0e17\u0e31\u0e25\u0e43\u0e19\u0e1b\u0e23\u0e30\u0e40\u0e17\u0e28\u0e44\u0e17\u0e22<\/a>.<\/p>\n

The one-year stay extension requires 4 Thai employees per foreigner<\/strong> (item 2.1(5) of the criteria annexed to Immigration Bureau Order 12\/2568); how long they must have been on social security before filing is office practice, often said to be about 3 months, so confirm at filing.<\/td>\nOrdinary DOE 2M\/4:1 package generally \u0e44\u0e21\u0e48<\/strong> the BOI filing route.

Path A: Self-sponsoring through your own Thai company (Non-B + WP)<\/h2>\n

Self-sponsorship means your Thai limited company meets the criteria to employ foreigners, then sponsors \u0e04\u0e38\u0e13<\/strong> (as director or employee) for a work permit, coordinated with a Non-Immigrant B stay. For mechanics and document checklists, see self-sponsoring a work permit through your own company<\/a> \u0e41\u0e25\u0e30 what a Thailand work permit is (and is not)<\/a>.<\/p>\n

Capital test (~2M \/ WP) and ceiling of ten + four exceptions<\/h3>\n

For a standard Thai company sponsoring a foreign work permit, the Department of Employment regulation of B.E. 2547 (clause 5(3)) sets the long-standing capital test of about 2 million baht paid-up registered capital per foreign permit<\/strong> (often 1 million<\/strong> where the applicant has a lawfully registered Thai spouse<\/strong>, \u0e2a\u0e33\u0e2b\u0e23\u0e31\u0e1a that spouse\u2019s permit only<\/strong>), with a general ceiling of ten<\/strong> foreigners unless one of the four exception tests<\/strong> in the B.E. 2547 criteria is met: corporate income tax paid \u22653M in the prior year; export foreign-exchange \u226530M; tourism \u22655,000 foreign visitors; or \u2265100 Thai employees.<\/p>\n

Thai staffing expectations (4:1 + SSO seasoning)<\/h3>\n

Separately, the one-year extension of stay requires the company to employ four Thai employees per foreigner<\/strong>. That ratio is item 2.1(5) of the criteria annexed to Immigration Bureau Order 12\/2568 of 23 January 2025, a condition Immigration applies to the extension, not a Department of Employment rule; representative, regional and branch offices of foreign companies are held to one Thai employee per foreigner instead. How long those employees must have been paying social security contributions before you file (often said to be about three months) is office practice<\/strong>, not a written rule, so confirm it with the office handling your file.<\/p>\n

Visa linkage (Non-B \u2192 WP \u2192 annual extension)<\/h3>\n

In practice, Non-B stay permission and the work permit move together: the permit is employer-, position-, and place-specific, and annual extensions usually require both to stay valid.<\/p>\n

One-year Non-B extensions<\/strong> tied to employment commonly require a minimum monthly salary that varies by nationality<\/strong> under Immigration practice (the criteria annexed to Immigration Bureau Order 12\/2568 of 23 January 2025; Police Order 327\/2557, often still quoted, was repealed in September 2023). Confirm the current band for the applicant\u2019s passport<\/strong> with the filing office before you rely on any published table, including this one.<\/p>\n

Real office, VAT, SSO, e-Work Permit workflow<\/h3>\n

Expect a real office that can survive a spot check, tax ID \/ VAT compliance where applicable, and SSO registration for staff. The e-Work Permit system for expatriates<\/a> changes \u0e22\u0e31\u0e07\u0e44\u0e07<\/strong> permits are issued; treat biometric and card timelines<\/strong> as operational and confirm current timelines with the Department of Employment rather than relying on a fixed number of days.<\/p>\n

Government WP fees for ordinary occupations remain on the published schedule: 100 \u0e1a\u0e32\u0e17<\/strong> application plus 750 \/ 1,500 \/ 3,000 baht<\/strong> by permit length up to one year (longer permits accrue the same bands; a two-year permit is often 6,000<\/strong> by that arithmetic).<\/p>\n

Main friction: capital, staffing practice, FBA ownership, nominees<\/h3>\n

Capital and staffing are only half the picture. Under the Foreign Business Act, a Thai-registered company that is 50% or more<\/strong> foreign-owned is itself a \u201cforeigner\u201d (s.4<\/strong>), and List restrictions apply. Thai nominee shareholding to evade the Act is a criminal offence<\/strong> \u0e15\u0e32\u0e21 section 36<\/strong> (imprisonment and\/or fines of 100,000 to 1,000,000 baht<\/strong>, plus court orders to unwind). From 1 \u0e2a\u0e34\u0e07\u0e2b\u0e32\u0e04\u0e21 2569<\/strong>, DBD Order 2\/2569<\/strong> tightens registration evidence for many under-50% foreign structures. The penalty that matters is the one in section 36 of the Foreign Business Act itself: up to three years\u2019 imprisonment, a fine of 100,000 to 1,000,000 baht, or both, and the court orders the arrangement to end.<\/p>\n

Path B: BOI-promoted route for founders<\/h2>\n

BOI promotion is activity-driven. It can unlock tax and non-tax incentives and a different visa\/WP channel, but only if your project sits on the live promoted list and you keep complying. See BOI promotion benefits and application<\/a>.<\/p>\n

FBA: \u226550% foreign = foreigner; List 2\/3 via s.12; List 1 closed<\/h3>\n

Under the Foreign Business Act, \u226550%<\/strong> foreign ownership makes the company a \u201cforeigner\u201d (s.4<\/strong>). BOI promotion can open a certificate route under FBA section 12<\/strong> \u0e2a\u0e33\u0e2b\u0e23\u0e31\u0e1a List Two or List Three<\/strong> activities, not List One<\/strong>, which remains closed to foreigners. Promotion is not an automatic List rewrite; the certificate follows promotion for qualifying List 2\/3 activities.<\/p>\n

WP\/visa via BOI channel (not ordinary DOE 2M\/4:1)<\/h3>\n

A BOI-promoted company sponsors foreign staff through BOI\u2019s visa\/work-permit channel (Single Window \/ TIESC), not the ordinary DOE capital-and-4:1 package. BOI still applies its \u0e40\u0e1b\u0e47\u0e19\u0e40\u0e08\u0e49\u0e32\u0e02\u0e2d\u0e07<\/strong> position-approval and (for larger manufacturing under Por. 8\/2568, employment >100<\/strong> \u2192 Thai personnel \u226570%<\/strong>) Thai-employment proportion rules. Published Single Window targets are on the order of several working days per step<\/strong> when documents are complete, not a guaranteed same-day result. BOI promotion therefore does not free a company from Thai staffing requirements.<\/p>\n

Tax \/ land \/ non-tax incentives<\/h3>\n

BOI tax incentives are activity-group dependent<\/strong>. Current published basic CIT exemption bands commonly run about 3 to 8 years<\/strong> (with some technology tracks and merit enhancements capable of longer totals, in limited cases up to around 13 \u0e1b\u0e35<\/strong>). Always match the exact activity<\/strong> on the live BOI list.<\/p>\n

Land: promotion can include a permission to own land<\/strong> for promoted operations where the foreign juristic person maintains paid-up capital of at least 50 million baht<\/strong> and meets BOI\u2019s current office\/residence criteria (Ann. 16\/2567 \/ Por. 8\/2567, late-2024 framework). Land ownership is not automatic<\/strong> with every promotion certificate.<\/p>\n

Minimum investment is often framed from about 1 million baht excluding land and working capital<\/strong>, activity-dependent.<\/p>\n

Eligibility, evaluation targets, ongoing compliance<\/h3>\n

After prep and complete documents, BOI publishes evaluation targets of roughly 40 \/ 60 \/ 90 working days<\/strong> by investment size. Promotion brings ongoing reporting and scope limits: benefits attach to the promoted<\/strong> activity, not to every side business you invent later.<\/p>\n

Spouse\/dependent on the BOI promotion path<\/h3>\n

A dependent visa issued because a spouse works for a BOI-promoted<\/strong> company does \u0e44\u0e21\u0e48<\/strong> automatically authorise the dependent to work. The dependent generally needs their \u0e40\u0e1b\u0e47\u0e19\u0e40\u0e08\u0e49\u0e32\u0e02\u0e2d\u0e07<\/strong> work authorisation. This is \u0e44\u0e21\u0e48<\/strong> the same as the Smart S spouse privilege described below, and the two tracks work differently.<\/p>\n

Path C: Smart S for startup founders (current track only)<\/h2>\n

February 2025 reform: Smart S + dependents only for new apps<\/h3>\n

As of the February 2025<\/strong> BOI Smart Visa reform (Cabinet 13 Jan 2025; BOI Announcement Por. 5\/2568<\/strong> of 18 Feb 2025, which repealed Por. 12\/2561), \u0e43\u0e2b\u0e21\u0e48<\/strong> Smart qualification is focused on startup entrepreneurs (Smart S)<\/strong> and their dependents<\/strong>. Do \u0e44\u0e21\u0e48<\/strong> rely on legacy Smart Talent \/ Investor salary or investment figures (e.g. Smart T \u2265100k monthly, Smart I 20M\/5M) as live gates for new applications.<\/p>\n

Current gates<\/h3>\n

Typical published gates include a certified targeted-industry startup (often framed as established within about two years), at least 25% equity or a director role<\/strong>, a bank deposit of \u2265600,000 baht<\/strong> (plus 180,000<\/strong> per dependent) held for at least three months<\/strong>, and health insurance.<\/p>\n

Work without traditional WP; spouse may work<\/h3>\n

Holders may work in endorsed activities without a separate traditional work permit<\/strong>. Under current Smart rules, a qualifying spouse may be permitted to work without a separate traditional work permit<\/strong>. That privilege belongs to the Smart<\/strong> track, and it does \u0e44\u0e21\u0e48<\/strong> transfer by analogy to a BOI-promotion dependent visa.<\/p>\n

Validity: up to 2 years, renewable<\/h3>\n

Smart S visa framing under current portal\/announcement materials is up to 2 years, renewable<\/strong>, not \u201cup to 4 years\u201d for new applications.<\/p>\n

How Smart S differs from Non-B self-sponsor and full BOI promotion<\/h3>\n

Smart S is immigration\/work facilitation<\/strong> for a narrow certified-startup profile. It is \u0e44\u0e21\u0e48<\/strong> a full BOI tax-holiday substitute, and it does \u0e44\u0e21\u0e48<\/strong> by itself rewrite FBA ownership rules. Self-sponsor Non-B + WP remains the default when your activity is ordinary SME work outside Smart\/BOI eligibility. Full BOI promotion remains the route when you need List 2\/3 ownership certificates, land permission potential, or activity-group tax incentives.<\/p>\n

How to choose: decision framework for founders<\/h2>\n
    \n
  1. Fast market entry vs ownership control vs sector incentives.<\/strong> If you need speed into an ordinary services business, self-sponsor Non-B may be more realistic than waiting on BOI evaluation, provided capital and staffing practice are fundable.<\/li>\n
  2. \u201cI need 100% foreign ownership.\u201d<\/strong> Look at BOI \/ treaty \/ Foreign Business Licence routes described in setting up a Thai company as a foreigner<\/a>, not nominees<\/strong>. Nominees invite FBA s.36<\/strong> exposure.<\/li>\n
  3. \u201cMy activity is not BOI-eligible.\u201d<\/strong> Plan a realistic Non-B self-sponsor structure (or another licence route), not a forced BOI story.<\/li>\n
  4. \u201cI\u2019m building a certified targeted-industry startup.\u201d<\/strong> Evaluate Smart S<\/strong> against BOI promotion and Non-B: deposit\/equity gates vs tax holiday vs capital-and-payroll load.<\/li>\n
  5. Spouse who will work.<\/strong> If the principal is on \u0e42\u0e1b\u0e23\u0e42\u0e21\u0e0a\u0e31\u0e48\u0e19 BOI<\/strong>, budget the spouse\u2019s \u0e40\u0e1b\u0e47\u0e19\u0e40\u0e08\u0e49\u0e32\u0e02\u0e2d\u0e07<\/strong> WP. If the principal is on Smart S<\/strong>, the spouse privilege may apply under Por. 5\/2568; confirm status before they start work.<\/li>\n<\/ol>\n

    Common mistakes that sink founder applications<\/h2>\n
