The short answer

You can open a Thai bank account if you live in Thailand on a long-stay visa — a non-immigrant O (retirement or marriage), B (work, with a work permit) or ED (study) visa, an LTR visa, or Thailand Privilege — or if you're married to a Thai or own property here. Bring your passport, proof of your Thai address, a Thai SIM card registered in your own name, and a small cash deposit.

Kasikornbank is the bank most often reported as saying yes to foreign residents, followed by Bangkok Bank and Krungthai. Branch managers have real discretion, so if one branch says no, try another — ideally one in an area with lots of foreign residents.

If you're visiting rather than living here, you almost certainly can't open a baht account in 2026. A fee-free UK card or a multicurrency account will serve you better anyway.

Who can open a Thai bank account in 2026

Your visa decides almost everything. This is how the major banks generally treat each status for a baht savings account. Individual branches vary.

Based on Bangkok Bank's rules from January 2025 as reported by TASS and Thailand Business News, and independent guides verified April–August 2026. The bank has the final say, branch by branch.

Why Thai banks stopped opening accounts for tourists

Thailand has a serious problem with phone and online scams, and the money from them moves through "mule" accounts — bank accounts opened in someone else's name and rented or sold to criminals. Accounts opened by short-term visitors, who then left the country, were a favourite. Four bank employees in Pattaya were arrested for helping scam-related accounts get opened.

The Bank of Thailand responded by pushing banks to tighten customer checks, and Bangkok Bank moved first. From January 2025, it required foreigners opening deposit accounts, applying for credit cards or registering for mobile banking to hold a long-term visa, be married to a Thai or own property. Tourists — including holders of the 180-day Destination Thailand Visa — were no longer eligible.

The same rules reached existing customers. Bangkok Bank froze some foreigners' accounts that didn't meet the criteria, and accounts with mismatches — such as a mobile number registered to someone else — were flagged for review. A frozen account isn't necessarily closed, but the holder may have to visit a branch and prove who they are.

What to take to the bank

Banks differ in the detail, but almost all of them ask for the same core set. Take originals and a photocopy of each, and sign the copies:

• Your passport with at least six months' validity, your current long-stay visa or extension stamp, and your latest entry stamp.
• Proof of your Thai address. The strongest is a residence certificate from your local Immigration office. A lease agreement plus a utility bill in your name is the usual alternative; documents in someone else's name often fail.
• A Thai mobile number registered in your own name with your passport — not your partner's, your landlord's or your employer's. The bank sends one-time passcodes to it and uses it to activate the app.
• A work permit if you're on a non-immigrant B visa, or a school letter if you're on an ED visa.
• Your opening deposit in cash, usually ฿500 for a savings account.
• A passport photo — some branches still ask for one.

Some branches also ask for a TM30 receipt (the form your landlord files to tell Immigration you live there), a reference letter from your embassy or employer, or evidence of income. Our guide to the documents commonly requested by Thai banks goes through each one.

Getting a residence certificate

A residence certificate is a short letter from Immigration confirming where you live. Banks, motor registration offices and utility companies all accept it. It depends on your landlord having filed a TM30 for you, and it's valid for 30 days.

It's Better in Thailand, fees as of March 2026. Bring your passport and copies, TM30 receipt, proof of address, two 4×6 cm photos and the application form; some offices also want your landlord's ID and house book.

The TM30: why it holds everything up

Thai law requires the owner of any property where a foreigner stays to report them to Immigration on a form called the TM30 — within 24 hours of arrival. Hotels do it automatically. Private landlords often don't, or don't know they should.

Without a TM30 on file, Immigration won't issue a residence certificate, and without a residence certificate many banks won't open your account. It also has to be refiled every time you return from abroad or move address. If you're renting, ask your landlord or agent to file it as soon as you move in and to give you the receipt — it can be done online.

In Bangkok, Immigration also wants to see that you've completed at least one 90-day report before it issues a residence certificate, which can block people who've only just arrived. If that applies to you, a lease and a utility bill in your own name, or a bank that accepts the TM30 receipt directly, may be quicker.

Which Thai bank to choose

All the big Thai banks offer much the same savings account, debit card and app. What differs is how readily they say yes to foreigners, and how they handle international money.

Krungsri (Bank of Ayudhya) is a solid fifth choice, though some of its accounts need a higher balance to avoid fees. Whichever you pick, check the branch is happy with your paperwork before you queue — a quick question at the information desk saves an hour.

How the appointment goes

You don't usually need an appointment — walk in, take a queue ticket and say you'd like to open a savings account. Weekday mornings are quietest. Allow an hour, sometimes two.

1. Check eligibility at the desk. Staff will look at your visa first. If it's not a long-stay visa, this is where it ends.
2. Fill in the forms. Account opening, debit card, mobile banking and often an insurance or savings product. Ask what each one is.
3. Identity checks. The bank copies your passport and visa, checks your name against fraud lists, and may take your photo or a face scan.
4. Pay your deposit. Usually ฿500 in cash.
5. Collect your passbook and card. Most branches issue the debit card on the spot; you'll set a PIN at a keypad.
6. Set up the app before you leave. Staff will help you install it, register your phone and, at most banks, link PromptPay to your mobile number.

Branch managers have real discretion, and the same bank can say yes in one branch and no in another. If you're refused, ask politely what's missing, then try another branch — a second branch the same day is perfectly normal. Branches in areas with many foreign residents are generally more used to the paperwork.

What a Thai bank account costs

Thai accounts are cheap to run, but the debit card and extras carry small annual fees.

After you open it: apps, PromptPay and face scans

The app is where a Thai account earns its keep. Once it's set up, you can pay almost anyone in Thailand by scanning a QR code, transfer money instantly to any Thai bank, top up your phone and pay bills.

PromptPay links your account to your mobile number, so people can send you money with just your number. It's how landlords, tradesmen and market stalls expect to be paid. Ask the branch to register it for you.

Face scans for larger transfers. Thai banks now ask you to confirm your identity with a face scan in the app for bigger payments. At SCB, for example, from 20 June 2026 foreign customers are asked for face recognition on transfers of ฿50,000 or more, each time daily transfers reach ฿200,000, when installing the app on a new phone and when raising transfer limits. If the bank doesn't already hold your face photo, you register it at a branch with your passport and passbook.

Keep your SIM active. If your Thai number lapses, you may be locked out of the app until you visit a branch. Top it up even when you're away.

Getting money into your Thai account

Once the account is open, you'll want to fund it from the UK — for living costs, rent, school fees or a visa deposit. How you send the money matters more than most people expect.

A standard UK bank transfer usually goes over SWIFT, with a fee from your bank, a margin in its exchange rate and sometimes charges from intermediary banks. The total is rarely clear in advance. Specialist providers such as Wise and Xe convert at or near the mid-market rate and show you how many baht will arrive before you send.

On ฿50,000 a month, sending through a low-cost provider and withdrawing from your own Thai bank's ATMs costs about £58 a year in our example — against nearly £600 using a standard UK debit card at Thai ATMs.

If you can't open one yet

If you're visiting, or you've just arrived and your long-stay visa isn't through yet, you have a few options:

Our UK travel debit card comparison and multicurrency account comparison show the best options side by side.

Setting up the rest of life in Thailand

A bank account is usually one of the first jobs on a long list. The long-stay visas that open the door to it often come with their own requirements — several, including the O-A retirement visa, ask for proof of health insurance — and once you're settled there are schools, healthcare and transport to arrange.

We've put together the practical side of moving here in one place: insurance quotes for health, car, motorbike, home and life, private healthcare and treatment, international schools, and moving with children and pets.

Keeping your account open

• Use it. Accounts with no activity for a long time can be made dormant or closed. A small transaction every few months keeps it alive.
• Keep your details current. Tell the bank when you renew your passport or visa; some banks now check that your visa is still valid.
• Keep the SIM in your own name and active, even when you're out of the country.
• Update your passbook at the bank's printing machine regularly if you use it for visa applications.
• Never lend or rent your account. Letting anyone else use it is how ordinary people end up involved in mule-account investigations.

How we researched this guide

Thai banks don't publish a single rule book for foreign customers, and practice varies between branches. We based this guide on Bangkok Bank's 2025 rules as reported by TASS and Thailand Business News, the banks' own published information (including SCB's face-recognition rules), and independent guides verified between March and August 2026. Fees and requirements were checked on 12 October 2026. Always confirm with your chosen branch before you go. This guide is general information, not legal or financial advice.
