How to Open a Bank Account in Thailand as an Expat in 2026 | THAIBK

Why a Thai Bank Account Matters

Some expats spend their first weeks in Thailand operating entirely on foreign cards, and this works as a short-term measure. The problems accumulate over time.

Thai ATMs charge a flat fee of 220 THB per withdrawal to foreign cardholders regardless of the amount withdrawn. At daily or every-other-day withdrawal frequency — which is common for those settling into a new city and spending across multiple categories — this adds up to a meaningful monthly cost. More practically, a Thai bank account is required for paying rent by transfer, setting up utility direct payments, managing the 800,000 THB deposit required for retirement visa renewal, and receiving any Thai-source payments. It also makes day-to-day life substantially easier once established.

Getting it set up early is worthwhile. The longer you leave it, the more friction accumulates.

Which Banks Accept Foreign Expats

Not all Thai banks are equally accessible to foreign nationals, and accessibility varies further depending on your visa type and length of stay.

Kasikorn Bank (KBank)

KBank is the most consistently recommended option for expats and digital nomads. Their K PLUS mobile app is well designed, available in English, and covers transfers, bill payments, and account management comprehensively. Branches in major expat cities — Bangkok, Chiang Mai, Pattaya — are experienced with foreign applicants and the documentation requirements are among the most clearly communicated of any Thai bank.

KBank is the first recommendation for most expats. Start here.

Bangkok Bank

Bangkok Bank has the most extensive international network of any Thai bank and is the most commonly used by expats who transfer money from overseas on a regular basis. Their international transfer infrastructure is well established and they have correspondent banking relationships with UK banks that make incoming transfers straightforward. The mobile app is functional if less polished than KBank's K PLUS. For those whose primary use case is receiving regular transfers from a UK account, Bangkok Bank deserves serious consideration alongside KBank.

SCB (Siam Commercial Bank)

SCB is another accessible option with a reasonable digital banking offering. Its SCB Easy app handles most day-to-day banking needs in English. Requirements for foreign applicants are similar to KBank. Less consistently recommended in expat communities than the two above but a solid choice if KBank or Bangkok Bank branches are less convenient.

Krungthai Bank and Krungsri

Both are large Thai banks with extensive branch networks. They are used by expats but are generally considered less straightforward for foreign applicants and their English-language digital banking is less developed. If KBank, Bangkok Bank, and SCB are accessible, prioritise those three.

What Documents You Will Need

This is where preparation matters most. The standard requirements across most Thai banks for a foreign expat savings account are:

Your passport, original and in date. Photocopies are usually also required.

Your visa or entry stamp. A valid visa — DTV, Non-Immigrant O-A, Non-Immigrant B, or similar long-stay category — significantly simplifies the process. Some branches will open accounts for those on tourist visa stamps, but this is branch-dependent and cannot be guaranteed. If you are on a tourist stamp, bring additional supporting documentation and be prepared to try more than one branch.

Proof of address in Thailand. This is the requirement that catches people most often. A rental contract in your name is the most straightforward form of address proof. Some branches accept a hotel booking confirmation for recent arrivals, though this is not universal. A utility bill, lease agreement, or letter from a landlord on headed paper all work once you are established in accommodation.

A local Thai phone number. Most Thai banks require a Thai SIM for account registration and for the OTP (one-time password) system that their mobile apps use. Purchase a SIM from AIS, True Move H, or DTAC before visiting the bank — these are available at the airport and at convenience stores throughout Thailand.

The opening deposit. Minimum opening deposits vary by bank and account type but are typically in the range of 500 to 2,000 THB. This is not a significant barrier but bring cash to the branch.

Some branches, particularly in tourist-heavy areas, have simplified the process for foreign applicants and will open accounts with less documentation. Others apply requirements strictly. If you are refused at one branch, try another — inconsistency between branches is a known feature of Thai banking and is not a reflection of your eligibility.

Setting Up Before You Leave the UK

The most useful financial preparation you can do before arriving in Thailand does not involve Thai banks at all.

Set up a Wise account. Wise (formerly TransferWise) offers mid-market exchange rates with low transparent fees for international transfers. For converting GBP to THB on a regular basis, the difference between Wise and a high street bank transfer is substantial — typically 3 to 5 percent of the transfer amount, which compounds meaningfully over a year of monthly transfers. Wise also provides a multi-currency account with a debit card that works at Thai ATMs and reimburses ATM fees up to a monthly limit.

Set up a Revolut account. Revolut offers similar functionality to Wise with some differences in fee structure and currency exchange limits. Many expats run both accounts and use each for different purposes — Wise for larger regular transfers, Revolut for day-to-day card spending and smaller conversions. Both are free to set up and verify in the UK before departure.

Notify your UK bank of your move. Some UK banks restrict card use or freeze accounts when spending patterns change dramatically — daily ATM withdrawals in Thailand from a card that previously showed only UK transactions can trigger fraud flags. Notify your bank before you travel. Also confirm that your UK account will remain accessible as a non-resident, as some banks have restrictions on this that vary by account type.

Consider your pension or income payment destination. If you receive a UK pension, salary, or other regular income into a UK account, ensure the receiving account will remain active and accessible from Thailand. For retirees, the 800,000 THB Thai bank balance required for visa renewal must be held in a Thai account — plan how you will fund this before arrival.

Transferring Money from the UK: The Practical Mechanics

Once you have both a UK account and a Thai bank account established, the regular transfer process becomes straightforward.

Wise transfers from GBP to THB typically settle within one to two business days. The rate is locked at the point of initiating the transfer, which provides predictability. For regular monthly transfers, setting up a recurring transfer on Wise is reliable and efficient.

Bangkok Bank has a specific service called Bangkok Bank London that allows direct transfers from UK bank accounts to Bangkok Bank Thailand accounts with competitive rates. For those who have chosen Bangkok Bank as their Thai account, this is worth investigating.

SWIFT transfers direct from a UK high street bank to a Thai bank account work but are significantly more expensive — fees of £15 to £25 per transfer plus unfavourable exchange rates make this the worst value option for regular transfers. Reserve direct SWIFT transfers for large one-off amounts where the percentage-based fee advantage of Wise becomes less significant.

The 800,000 THB Retirement Visa Deposit

For retirees on the Non-Immigrant O-A visa, the 800,000 THB bank deposit requirement deserves specific attention in any banking guide.

The funds must be held in a Thai bank account in your name. They must be present at the time of visa renewal application and must have been in the account for a demonstrable period — typically three months prior to renewal is the standard most immigration offices require, though this varies by region. The funds must remain in the account through the renewal process.

This is not a cost — the money remains yours. But it is a capital commitment. You cannot use those funds for living expenses without risking your visa renewal. Factor this into your overall financial planning before arriving: you need 800,000 THB accessible for the deposit plus sufficient additional funds for living expenses and contingencies.

Bangkok Bank and KBank are the most commonly used accounts for this purpose, both because of their accessibility and because their account statements are well recognised by immigration offices across Thailand.

Common Mistakes to Avoid

Waiting too long to open an account. Every week operating on foreign cards costs money in ATM fees and unfavourable exchange rates. Prioritise the bank account in the first two weeks.

Relying solely on one account. Technology fails, cards get blocked, apps have outages. Operating with a Thai bank account, a Wise account, and a backup Revolut card gives you redundancy. The cost of the backup is minimal; the cost of being unable to access funds in a foreign country is not.

Using a high street bank for regular transfers. The fee and exchange rate disadvantage of high street bank international transfers relative to Wise is significant over time. There is no good reason to use a high street bank for regular GBP to THB conversions once Wise is set up.

Forgetting the 90-day reporting obligation. This is a banking guide, not an immigration one, but the two intersect for retirees whose 800,000 THB deposit is tied to visa compliance. Missing a 90-day report creates immigration complications that can in turn create complications for the bank balance requirement. Keep both in order.
