Opening a Thai bank account: the word that decides it is not “visa”

Every English guide to this organises itself around visa classes — Non-B yes, tourist no, retirement maybe. The Thai instruments that actually govern the question are organised around a different word:  ถิ่นที่อยู่ , residence. It decides the score a bank starts you on, which family of account you are put in, and — the part nobody mentions — whether the state’s million-baht deposit guarantee reaches your money at all.

The question everyone asks is the wrong one

Search in English for how to open a Thai bank account and you will be handed a table of visa classes. Non-B, yes. Non-O for marriage, yes. Education visa, probably. Tourist, no — or yes, at this one branch in Pattaya, according to a forum post from four years ago. The table is presented as though it were the rule.

It is not the rule. It is a summary of behaviour, collected from people who succeeded or failed at particular counters, and it is unstable for the same reason that any summary of behaviour is unstable: the underlying thing being summarised is a judgement, not a test. Nothing published requires a Non-B visa for a deposit account. Nothing published forbids one to a tourist. What is published is a framework for deciding how much a bank should worry about you, and a set of consequences that follow from where you land in it.

So it is worth reading the framework directly, because it turns out to be short, oddly readable, and organised around a word that the English guides almost never use.

What the rules actually ask for

Identification of customers by Thai financial institutions is governed by the anti-money-laundering regime — a ministerial regulation on customer due diligence made in 2020, and guidance published by the Anti-Money Laundering Office setting out how to apply it. We read the June 2022 edition of that guidance in full.

For a foreign individual, the document it names is a passport. The verification methods it describes are electronic — read the chip over the phone’s near-field radio and compare what comes back against the printed page — or human, an officer examining the evidence and certifying that the customer is the person it describes. That is the requirement.

There is exactly one fallback, and it is not the one people expect. It is for a foreign individual who has no passport:

Read that carefully and a familiar cast of characters is missing. No work permit. No lease. No employer’s letter. No certificate of residence. No 90-day report receipt. None of them appears anywhere in the identification requirement for a foreign customer, and their absence is not an oversight, because the same regime is extremely specific about identification elsewhere.

Which raises the obvious question, and the answer to it is the useful part of this page.

Why the branch asks for more anyway

Because the regime does not stop at identification. It tells institutions to grade every customer for risk and to calibrate what they do next — how much they verify, how closely they monitor, whether they proceed at all — to the grade. And in an annexe, the office publishes an illustration of how such grading might be scored.

The scale runs from 1 to 4. A civil servant whose only income is a salary scores 1. A freelancer with several income streams that cannot be checked precisely scores 2. A company with an abnormally complex shareholding structure scores 3. A politically exposed person scores 4, as does a name matching the office’s high-risk list.

And sitting on the same line as the opaque shareholding, at 3, is this: a customer who has no residence in the country. Not a foreign national. Not a tourist. A person without residence.

Where more than one factor applies, the guidance says, take the highest.

That single row explains the whole document pile. A branch confronted with a foreigner it has no basis to place is looking at a customer-axis score of 3 out of 4, before anything else is added — and area, product and channel scores stack on top of it. A lease, an employer’s letter, a residence certificate, a utility bill in your name: every one of those is evidence that the row does not apply to you. The bank is not running a legal checklist. It is managing a number, and you are being asked to help it move the number.

Once you see it that way, the counter conversation changes shape. The question is no longer “which document do I legally need” — there is no such document — but “what would persuade you that I live here?” Those are different questions, and the second one has more than one right answer.

The worked example, and what it quietly assumes

The same guidance gives a table of total risk scores for imaginary customers, adding the customer factor to factors for area, product and channel, with bands of 4–7 for low risk, 8–11 for medium and 12–16 for high.

Two things are worth noticing. The first is arithmetic: the foreign customer and the customer on the regulator’s high-risk list arrive at the same total, 11, by different routes. Nobody is suggesting they are the same kind of customer. But if the bank’s procedures are keyed to the band rather than to the reason, they get the same treatment.

The second is what the example does not say. It describes Miss A only as a foreign national from Japan and scores her 3. The weights table above it contains no row for nationality at all. The only individual-customer row carrying 3 is the one about residence — so the example appears to be applying that row to a foreigner without further explanation. We think that reading is close to certain. We are still flagging it as our inference rather than the document’s statement, because the document does not connect them for you, and the difference matters: on the weights table as written, a foreigner who does have residence here has no reason to score 3 at all.

The address, and the duty that belongs to somebody else

If proving residence is the game, the obvious move is to bring proof of an address. Here Bangkok arranges a small trap.

Under section 38 of the Immigration Act B.E. 2522, when a foreigner permitted to stay temporarily takes up residence somewhere, it is the house owner, the householder, the possessor of the dwelling or the hotel manager who must notify the immigration office for that locality — within 24 hours. Not the foreigner. The reported penalty for failing to do it runs from 800 to 2,000 baht per foreigner accommodated.

That notification, the TM.30, is the foundation the rest of the address paperwork sits on. Which means the first document in the chain is one your landlord is legally responsible for filing, that you cannot file for them, that you may never see, and whose absence will nonetheless be your problem at a bank counter or an immigration desk. It is the same structure we found in the city’s animal registration rules: a duty placed on the landlord, a consequence landing on the tenant.

The practical advice is unglamorous and worth following anyway. Ask, before you sign, whether the owner or the building files TM.30 notifications, and whether they can give you the receipt. Buildings that let to foreigners routinely usually do it as a matter of course. Individual owners letting one unit sometimes have never heard of it.

Which account you were given, and why it decides more than it looks like

Thailand’s exchange control rules recognise a separate family of accounts for people whose residence is outside the country: the non-resident baht account, used for trade, services, direct investment, property and lending, with a companion account for securities. It is an ordinary enough piece of plumbing, and on its own it would be a technicality.

It stops being a technicality when you read the deposit guarantee.

Deposits at institutions under the deposit protection law are guaranteed to 1,000,000 baht per depositor per institution. The Deposit Protection Agency’s own answer to the question of who is covered names natural persons “both Thai and foreigners who have residence in Thailand”, and adds that the account “must be a baht account only”. Its list of what is not protected includes foreign currency deposits — and, explicitly, deposits in a non-resident baht account.

So the same word, residence, does a third job. It decides the score a bank starts you on, it decides which family of account you belong in, and through that it decides whether the state guarantee reaches your savings. Nobody tells you the answer. There is no line on the passbook that says which one you got.

We want to be careful about how far we push this, because there is a gap in what we could establish. We did not find the exchange control definition of residence — the central bank’s own pages for exchange control law do not carry it, and it lives in a consolidated regulation we did not read. So we cannot tell you where the line falls, whether a work permit or a year’s permission to stay puts you on the resident side, or how any particular bank classifies a long-stay foreigner in practice. Every English source that answers those questions confidently is a visa agency.

What we can say is narrower and still useful: the categories exist, the exclusion from deposit protection is published and specific, and it is a reasonable thing to ask your branch outright. Is this account a resident baht account? is a question a counter can answer, and it is the only one on this page whose answer is worth a million baht.

After it opens: two numbers that will surprise you

The account existing is not the end of it. Two central bank measures shape what you can do with it, and both of them fall hardest on new customers.

The daily limit you did not choose

In August 2025 the Bank of Thailand set out per-customer daily limits on transfers and payments, with the lowest band at 50,000 baht a day. The regulator was explicit that this is not a blanket cap and that most customers would get limits matching their normal patterns, with higher bands for people who routinely move more.

The groups it named for the lowest band were customers assessed as potential fraud risks, customers whose transfers do not exceed the figure anyway — and customers with limited banking history.

A person who opened their first Thai account six weeks ago has, by definition, limited banking history. There is nothing punitive about it and nothing to appeal; it is simply what the file looks like. But it is worth knowing on the day you are trying to move a deposit and two months’ rent to a landlord and the app declines at 50,000. Higher limits are requested from the bank through the app, the call centre or a branch, and a large one-off payment can be made over a counter. Both of those take a working day you may not have planned for.

The face scan at 50,000

Separately, banks were instructed to require facial verification instead of a one-time password for transfers of 50,000 baht or more, alongside an existing ceiling of 200,000 baht a day in total on mobile transfers. The central bank’s stated reason for choosing that threshold was proportionality: transfers at or above it are only about one per cent of daily mobile banking transactions, so the friction lands on a thin slice.

For a foreign customer the consequence is a small piece of setup. Your face has to have been enrolled, which is normally done in the branch or through the app at opening, and it has to still work — banks periodically ask customers to rescan. It is the sort of thing nobody thinks about until the evening it stands between them and a payment.

The two numbers being the same is a coincidence of drafting, not a single rule. One is a limit on how much you may move; the other is a rule about how you prove it is you. It is possible to be stopped by both in one evening, which is a special kind of annoying.

What we could not establish

More than usual on this one, and the gaps are worth stating plainly because the internet is full of confident answers to exactly these questions.

• Which visas actually work at which banks. There is no published rule, and we are not going to launder forum reports into one. What we can tell you is what the rules require, which is a passport, and what the bank is optimising, which is a risk band.
• Where the exchange-control line between resident and non-resident falls for a foreign individual, and whether long-stay foreigners are in practice given ordinary resident accounts. The definition is in a consolidated regulation we did not read.
• The fee, waiting time and prerequisites for the address letter that banks ask for. We could not find the authority’s own page; the agency blogs disagree with each other, quoting anything from free to 500 baht.
• Whether any bank publishes its own foreign-customer document list in English. We did not find one we were willing to cite as the bank’s own statement.
• The account-freezing regime introduced for technology crime, which is real and does affect foreign account holders. We did not read the decree this time, so we have left it out rather than summarise it second-hand.

Questions people actually ask

So can I open an account on a tourist visa or not?

Nothing published forbids it, and nothing published entitles you to it. On the framework above, a visitor is the clearest case of the customer the weights table scores at 3, with nothing available to bring the number down, so a branch declining is a branch doing what the regime tells it to do. If a branch agrees, that is also within the rules. This is the honest answer and it is unsatisfying; the satisfying answers you will find elsewhere are people generalising from one counter on one afternoon.

Which bank is best for foreigners?

We are not going to rank them, because we have no basis to. What we would look at, given what is on this page, is narrower than a ranking: whether the branch will tell you which account family you have been put in, whether it can enrol your face at opening rather than sending you back, and what it takes to move off the lowest transfer band. Those three answers vary by branch as much as by bank, which is the awkward part.

My landlord says the TM.30 is my job. Is it?

Not on the face of the statute. Section 38 places the duty on the house owner, householder, possessor of the dwelling or hotel manager who accommodates the foreigner, with a 24-hour deadline. There are online filing routes and there are situations — owners abroad, informal sublets — where the practical arrangement is that the tenant handles it. That is an arrangement, not a reallocation of the duty. We would ask for the receipt either way, because the receipt is the thing that ends up mattering downstream.

Does having a Thai company or a work permit change any of this?

It plainly changes what you can show a bank, which is the point of the section above on buying down a score. Whether it changes your status under exchange control is exactly the question we could not answer, so we are not going to imply an answer by putting the two next to each other. If your money in Thailand runs to seven figures, that is a question for a Thai lawyer or the bank’s own compliance desk, and it is a reasonable one to put in writing.

Is the million-baht guarantee per account or per person?

Per depositor per financial institution, not per account — four accounts at one bank share one guarantee, one account at each of four banks does not. The agency also publishes that at the current limit the guarantee fully covers something over 98 per cent of depositors in the system, which tells you who the limit was calibrated for. For a foreign resident with a property deposit sitting in one bank, the arithmetic is worth doing once.

Why does everything here hinge on a word rather than a document?

Because the instruments are written for institutions, not for customers. A rule that said “foreigners must produce a work permit” would be easy to read and easy to evade; a rule that says “grade the customer, and here is what a customer without residence looks like” pushes the judgement down to the counter. That is deliberate, and it is why the same passport gets different answers at different branches without anyone breaking a rule.
