Opening a Thai Bank Account as a Foreigner
Share
Opening a Thai bank account got harder in 2025 and harder again in 2026. The requirements are now policy set at head office rather than discretion exercised at the counter, which means turning up at a different branch works less often than it used to.

Why you need a Thai bank account
If you are extending a retirement visa using the deposit method, immigration requires 800,000 baht held in a Thai bank. A foreign account does not satisfy it. The money has to sit in a Thai institution, in your name, and it has to have been there long enough.
Day to day, Thailand runs on QR payments through Thai banking apps. Rent, utilities, market stalls, taxis. A foreign card covers a holiday. It does not cover living here.
Not every long-stay route needs one. The DTV asks for its 500,000 baht in your own bank at home, so no Thai account is involved in that application at all.
Can you open a Thai bank account on a tourist visa?
No. Most major Thai banks now require a long-term non-immigrant visa before they will open a personal account. Tourist visas and visa exemption entries are out. Bangkok Bank, Kasikorn and SCB all tightened between January 2025 and January 2026.
The change came after the mule account problem of 2024 and 2025, where short-stay foreigners were recruited to open accounts used for laundering scam proceeds.
This creates a sequencing problem for retirees. The 800,000 baht has to sit in a Thai account for two months before you apply for the extension. You cannot open that account without a non-immigrant visa.
The order that works
Trying to do it in any other order is where people get stuck. The visa options page covers the routes in full.
How mine was opened
I hold a Bangkok Bank account, opened in 2024 through TMT Visa Service in Phuket. They did it in person, with me sitting there.
That route is gone. TMT no longer offers account opening as a standalone service, and the banks have tightened twice since.
One thing from that day is worth repeating. The bank arranged an insurance policy at the same time. That was a condition the bank attached, not an immigration requirement for a Non-O retirement visa or extension. If a bank or an agent tells you insurance is needed, ask which of the two is asking for it.
What an agent does now, and what to ask before you engage one, is on the visa agents page.
Can DTV holders open a Thai bank account?
Thai banks treat the DTV as a tourist visa when they run their identity checks, regardless of its five-year validity. Bangkok Bank, Kasikorn and SCB all reject DTV holders for new accounts.
Anyone planning to use the DTV as their route into Thailand should assume no Thai bank account and plan their money around a multi-currency account instead. That applies at any age, since the DTV has no upper age limit and people well past 50 use it.
What the DTV does and does not allow, including the 500,000 baht it asks for and the 180-day limit, is set out on the DTV visa page.
Documents you need
- Passport, with at least six months validity.
- Non-immigrant visa or extension stamp.
- Proof of a Thai address. A rental agreement plus a utility bill is the usual combination.
- A certificate of residence from your local immigration office, if the branch asks for one. Some branches insist, some do not. Some embassies issue an equivalent letter for their own nationals.
- Your Thai phone number, for the banking app and for one-time passwords.
Get the Thai SIM before the bank appointment. Mobile banking is set up at the counter and it needs a working local number.
Which Thai bank is best for foreigners?
Reported experience across banks in 2026:
| Bank | For retirees | Notes |
|---|---|---|
| Kasikorn | Most accessible | K PLUS app has a full English interface |
| Bangkok Bank | Workable | Long the default for foreigners, and the one that tightened hardest. This is the one I bank with |
| Krungthai | Workable | Government owned, and has been flexible with Non-O retirement and marriage holders |
| SCB | Stricter | Reported as accommodating for LTR holders specifically |
| TTB | Unlikely | Generally wants a work permit, so not a natural fit for retirees |
Branch still matters even though policy is now centralised. Branches in areas with a lot of foreign residents process these applications regularly and know the paperwork. A refusal at one branch is worth retrying at another before concluding you are ineligible.
How long does the 800,000 baht have to sit in the account?
For a first retirement extension the money generally needs to have been in the account for at least two months before you apply. Immigration officers call this seasoning. It means the balance has to have been there, untouched, for long enough to prove it is genuinely yours rather than borrowed for the day of the appointment.
After approval it must stay for three months, and must not fall below 400,000 baht for the remainder of the year.
Two things follow from that:
- Move the money early. Immigration counts days, and a transfer that arrives a week late costs you the whole application window.
- Keep the account statements. You will need the bank to issue a letter confirming the balance and where the money came from when you apply.
That 800,000 baht is locked capital rather than spending money, which changes the sum in how long your savings will last in Thailand. The DTV asks for less and does not lock it, which is why some people over 50 pick it instead.
Transferring money into a Thai account
International transfers into Thai accounts arrive through SWIFT, the system banks use to move money between countries. They usually land within one to three business days.
Bank exchange rates are rarely the best available, and services such as Wise are commonly used for the conversion.
One caution. For visa purposes some immigration offices want to see that the funds arrived from overseas rather than appearing from inside Thailand. Keep the transfer records.
Not financial advice
Bank policies change and branch practice varies. Confirm current requirements with the specific branch before you travel to it, and confirm the deposit rules with the immigration office that will handle your extension.
