Building a Thai startup
You are incorporating or have incorporated a company in a targeted industry and can obtain an endorsement from an authorised agency. SMART S is designed for exactly this.
Working and doing business hereA specialist route for startup founders — and, for almost everybody else, the wrong door.
The SMART Visa has a reputation problem. It sounds like the sophisticated option — a government-backed route for skilled people, with no work permit and no 90-day reporting — and that reputation was built when the programme had four different categories aimed at employees, investors and executives.
That version of the programme is gone. Since the reform announced in February 2025, SMART is essentially a startup visa. If you are building a company in Thailand in one of the targeted industries, it is worth taking seriously. If you are a remote worker, a salaried professional, an investor or a well-paid employee, the honest answer is that the DTV, LTR or Non-B will almost certainly serve you better.

Most SMART Visa articles online are out of date
BOI Announcement No. Por 5/2568, issued in February 2025, restructured the programme around SMART S and SMART O. Guides that still describe SMART T, SMART I and SMART E — with their salary thresholds and investment figures — are describing categories that are no longer open to new applicants.
Criteria, fees and processing arrangements are set by the Board of Investment and can change. Confirm everything on the official programme site before you commit time or money. This is general relocation information, not immigration or legal advice.

The one-line test
If your reason for being in Thailand is a Thai company you are building, SMART S is worth investigating. If your income comes from outside Thailand, or from a Thai employer who can sponsor you, it is not your route.
The programme narrowed sharply, and most of the internet has not caught up.
SMART launched as a package of categories: talent, investor, executive, startup and the family members attached to them. It was designed to attract skilled individuals into Thailand's targeted industries without putting each of them through the conventional work-permit machinery.
The February 2025 announcement kept the mechanism and dropped most of the audience. New applications now run through SMART S for startup entrepreneurs, with SMART O for a spouse and children. The talent, investor and executive categories are closed to new applicants, which removes the salary and investment pathways that made the programme interesting to a much wider group of people.
Practically, that means the comparison articles ranking SMART against the LTR on income thresholds are comparing something that no longer exists. If a page quotes a monthly salary figure for SMART T, treat everything else on it with suspicion.
The honest version, because the wrong applicants waste months here.
You are incorporating or have incorporated a company in a targeted industry and can obtain an endorsement from an authorised agency. SMART S is designed for exactly this.
Working and doing business hereNo Thai company, no endorsement, no SMART. The DTV is the route built for this pattern of life and it is far less conditional.
Read the DTV guideIf you meet one of the BOI LTR categories, LTR gives longer permission with less dependence on a single business succeeding.
Read the LTR guideAn employer that can sponsor you belongs in the Non-B and work permit process, which is well trodden and predictable.
Read the Non-B guideThere is one more group worth naming: people who like the sound of annual reporting and no work permit, and who are trying to reverse-engineer a startup to qualify. The endorsement process exists precisely to filter that out, and a business built to satisfy an immigration criterion tends to fail both tests at once.
Two years of permission, conditional on a genuine, endorsed venture.
The endorsement is the part people underestimate. Before the visa itself is considered, an authorised agency has to certify that the startup belongs in a targeted industry and is credible. That judgement rests on the business — the product, the plan, the team — rather than on your personal profile, which is the opposite of how most visa routes work.
Once the company is incorporated, the programme expects a real stake in it: a shareholding of at least a quarter of the registered capital, or a directorship. SMART S is not a route for a passive founder listed on paper.
Two requirements that quietly decide your timeline.
The published financial requirement is 600,000 THB, or the equivalent in another currency, in the applicant's own account. The figure itself is manageable for most founders; the seasoning is what catches people. The funds are expected to have been held for at least three months before the application, so this is a decision to make a quarter ahead of your intended move, not during it.
Each family member applying under SMART O adds a further 180,000 THB on the same basis. A founder moving with a spouse and two children is therefore looking at well over a million baht sitting still for three months, on top of whatever the business itself needs.
Health insurance covering the period of stay is also required, for the principal and for accompanying family members. Buy it against the actual length of permission you expect rather than a single year, and check that it will still be valid if the visa is renewed.
Your business has to sit inside one of these, as BOI defines it — not as you describe it.
The list has been revised more than once since the programme launched, and the definitions matter more than the labels. "Digital" in particular covers a specific set of activities rather than anything with software in it. Check your intended activity against BOI's own definitions before you build a plan around qualifying.
A derived status, with its own money.
A legal spouse and children can apply under SMART O alongside the principal applicant. The permission tracks the principal's, which means it also ends with it: if the startup status falls away, so does the family's basis for staying.
Work rights for SMART O holders changed with the 2025 reform, and the current position is not something we can state with confidence. If a spouse intends to work, confirm that directly with the TIESC before making it part of your plan.
If SMART O does not work out for your family
Families in Hua Hin more often end up on the ordinary dependant and guardian routes, which are governed by immigration criteria rather than by BOI. Those are covered in the guardian and dependant visa guide.
The privileges are real. They are just attached to a narrow qualification.
Work is authorised within the scope approved in the SMART endorsement. Step outside that scope and you are back in ordinary work-permit territory.
SMART holders report to immigration once a year rather than every 90 days — one of the programme's genuinely useful practical benefits.
Leaving and returning to Thailand does not cancel the permission to stay, so the usual re-entry permit purchase before each trip does not apply.
A spouse and children can be brought in under SMART O, subject to the additional deposit for each person.
Annual reporting and the absence of a re-entry permit are worth more in daily life than they sound on paper. Anyone who has queued twice a year for a 90-day report and bought a re-entry permit before every trip understands the difference. But these are conveniences, not reasons to choose the route — and a TM30 address notification is still expected when you move into a property.
Two stages, in a fixed order. The second cannot start until the first is done.
From idea to visa
Check the activity against the targeted industries
Before anything else, confirm with BOI that what you intend to build falls inside a qualifying activity as they define it.
Prepare the business and the company
Business plan, incorporation documents, ownership structure and the evidence that the venture is real.
Obtain the qualification endorsement
An authorised agency assesses the startup and endorses it. This is the gate the whole route depends on.
Season the funds and arrange insurance
600,000 THB held for at least three months, plus 180,000 THB per family member, and health insurance covering the stay.
Apply for the SMART Visa
Submitted through the BOI SMART Visa system, with the endorsement attached.
Collect the visa or convert in Thailand
Issued at a Thai mission abroad or at the service centre in Bangkok, depending on where you are when approval comes through.
Published processing times exist for each stage, but they assume complete documentation and a straightforward assessment. Treat the whole thing as a project measured in months and keep a fallback entry route available so that a delay does not leave you outside Thailand with no plan.
Indicative rather than exhaustive — the endorsing agency sets its own list.
For most people reading this page, one of these is the answer.
Remote work for overseas clients or an overseas employer, five years of validity, no Thai company required.
DTV guideHigh income, substantial assets or qualifying expertise. Longer permission and the same annual reporting benefit.
LTR guideThe conventional route for employment with a Thai company, or for running an ordinary Thai business outside the targeted industries.
Non-B guideA paid membership route for people who want long-term access without a business or income qualification.
Thailand Privilege guideThe company can be here. The process largely is not.
Nothing about SMART requires the business to be in Bangkok, and Hua Hin is a perfectly reasonable base for a small team: it is close enough to the capital for day trips, and the cost of running a life here is markedly lower. What you should expect is travel. The service centre that handles SMART Visa issuance and endorsement sits at One Bangkok, having moved from Chamchuri Square, and most agency contact happens there.
Bank onboarding is the other local factor. Opening a Thai account as a newcomer is achievable but rarely quick, and the three-month seasoning clock cannot start until the account exists and the money has arrived.
Most of them start with reading something written before February 2025.
Most of what circulates online still describes SMART T, SMART I and SMART E. Those categories are no longer open to new applicants, so the salary thresholds and investment figures in older guides no longer lead anywhere.
SMART is not a remote-work route. Working online for an overseas employer or overseas clients is DTV or LTR territory, not SMART.
The endorsement from an authorised agency is the gate. Without it there is nothing for the TIESC to qualify, however good the business idea is.
The funds are expected to have been held for at least three months before the application. Money transferred the week before does not satisfy that test.
Work authorisation attaches to the approved scope and the approved company. A different role or a second venture generally needs to go back through the process.
For most people the honest answer is that another route is quicker, cheaper and less conditional. SMART only makes sense if the startup itself is the reason you are here.
The questions that come up when someone works this out for the first time.
Yes, but in a narrower form. Following BOI Announcement No. Por 5/2568 of February 2025, the programme is focused on SMART S for startup entrepreneurs and SMART O for their qualifying family members. The former SMART T, SMART I and SMART E categories are no longer open to new applicants.
No. SMART is built around a Thai startup in a targeted industry, not around overseas income. Remote workers should look at the DTV, and highly paid remote employees of large overseas companies at the LTR Work-from-Thailand category.
The published requirement is 600,000 THB (or the equivalent) in the applicant's own account, held for at least three months before applying, with an additional 180,000 THB for each family member applying under SMART O. Confirm the current figures with BOI before you plan around them.
Not a conventional one. Work authorisation is granted within the scope approved as part of the SMART endorsement. Anything outside that approved scope is not covered.
No. SMART holders report annually rather than every 90 days, and do not need a re-entry permit to leave and return to Thailand.
Work rights for family members changed with the 2025 reform and are not stated in a way we can present with confidence. Confirm the current position directly with the TIESC before making plans that depend on a spouse working.
It runs in two stages — qualification endorsement first, then the visa itself. Timeframes depend on the endorsing agency and on how complete the company documentation is, so treat any single published figure with caution and build slack into your moving date.
The company and the endorsement process are national rather than Bangkok-specific, but the TIESC counter and most of the agency contact happen in Bangkok. Plan on travelling for the process even if the business itself is based here.

The restructuring of the programme around SMART S and SMART O, the 600,000 THB and 180,000 THB deposits with their three-month holding period, the annual reporting and re-entry arrangements and the service centre location are taken from BOI programme material and the February 2025 announcement. Work rights for SMART O family members are deliberately left open rather than stated, because the current position could not be confirmed to our standard. Processing times are described qualitatively for the same reason.
