Banking for Thailand-Based Expats: Restrictions, FET Forms, and Managing Your Finances in Thailand

Thailand remains one of Southeast Asia's most popular destinations for British and Western expats, offering a warm climate, low cost of living, world-class cuisine, and — for retirees and remote workers — a genuinely comfortable lifestyle at a fraction of comparable UK costs. However, the Thai banking system is notably more restrictive for foreign nationals than most other countries discussed in this series, and understanding the rules before you arrive will save significant frustration.

This guide is for general information only and does not constitute financial, legal, or tax advice. Thai banking regulations, visa conditions, and tax rules change regularly; always consult a qualified Thai lawyer or financial adviser before acting.

Thai Banking Restrictions for Non-Residents

Thailand restricts the ability of foreigners to open and operate bank accounts in ways that may surprise arrivals from more open banking jurisdictions.

Basic rules:

• Foreign nationals can open a savings account (บัญชีออมทรัพย์) at most major Thai banks, but typically require a non-immigrant visa (not a tourist visa)
• Tourists on visa exemption or 30/60-day tourist visas are generally unable to open accounts at mainstream banks
• Account types available to foreigners are often limited to basic savings accounts initially; current accounts and more complex products may require longer residency documentation
• Foreign Exchange Transaction (FET) forms (see below) must accompany any transfer of foreign currency into Thailand exceeding USD 50,000 (or equivalent)

The degree of restriction varies by bank, branch, and the judgement of individual branch managers — practices are not always uniformly applied.

Major Thai Banks

Kasikorn Bank (KBank)

Kasikorn (often called K-Bank by expats) is consistently rated as the most foreigner-friendly of Thailand's major banks. Its K-Plus mobile banking app is well-regarded and offers English-language functionality. Kasikorn has dedicated international transaction services and processes international SWIFT transfers reliably. Many expats in Bangkok and Chiang Mai use Kasikorn as their primary bank.

Bangkok Bank

Thailand's largest bank by assets has a long history with international customers. Bangkok Bank operates representative offices in several countries and has historically been used by expats and foreign investors for property purchase-linked accounts. Its branch network is extensive and it has English-language phone and online support.

SCB (Siam Commercial Bank)

SCB, Thailand's oldest bank, has invested in digital transformation with its SCB Easy app and is a mainstream choice for both Thais and long-term foreign residents. It offers English-language services at major branches.

Krungsri (Bank of Ayudhya)

Majority owned by Japanese banking group MUFG (Mitsubishi UFJ Financial Group), Krungsri has a solid reputation and benefits from its Japanese parent's systems and compliance standards.

Krungthai Bank

Krungthai is government-owned and Thailand's second largest by assets. It handles a large proportion of government salary payments and pension distributions, and maintains a very wide ATM network.

Documents Typically Required

Opening a Thai bank account as a foreign national typically requires:

• Valid passport with at least 6 months validity
• Non-immigrant visa in your passport (retirement, business, education, or Long-Term Resident visa — see below)
• Thai address documentation (rental agreement, proof of residence from a local guarantor, or a yellow household registration book (tabien baan) if registered)
• Proof of income or financial means may be requested for some account types
• Initial deposit (typically THB 500–5,000 depending on account type and bank)

Some banks, particularly Kasikorn and Bangkok Bank at major branches in tourist areas, have periodically opened accounts for visitors on tourist visas — but this is not guaranteed and has become less common following stricter compliance enforcement from the Bank of Thailand.

Long-Term Resident (LTR) Visa Holders and Banking Access

Thailand launched the Long-Term Resident (LTR) visa in 2022, designed to attract wealthy individuals, pensioners, remote workers, and skilled professionals. LTR visas offer 10-year renewable stays with various tax and work permit benefits.

For banking purposes, LTR visa holders are among the most straightforwardly served foreign nationals in the Thai banking system:

• All major banks accept LTR visas as valid documentation for account opening
• LTR holders may access a wider range of account types than standard non-immigrant visa holders
• The BOI (Board of Investment) — which administers LTR visas — can provide documentation letters that some banks accept alongside the visa
• LTR visa holders bringing qualifying funds into Thailand may benefit from income tax exemptions on certain foreign-source income remitted to Thailand; banking arrangements should be structured to evidence the relevant fund flows

Tax treatment of LTR visa holders' income is a specialist area; obtain advice from a Thai tax lawyer before remitting significant sums.

SWIFT Transfers into Thailand

Thailand uses SWIFT for international wire transfers. Key points for expats:

• Thai banks process incoming SWIFT transfers in major currencies (GBP, USD, EUR, AUD, SGD, and others)
• The Bank of Thailand's cross-border payment regulations require documentation for transfers above certain thresholds
• Receiving SWIFT transfers: provide your bank's SWIFT/BIC code, your account number, and the bank's address; always include a clear purpose of payment in the SWIFT message (e.g. "living expenses", "property purchase", "salary") — vague descriptions can trigger additional AML queries and delays
• Processing times for incoming international transfers are typically 1–3 business days; delays are not uncommon, particularly for first-time large transfers

For regular smaller transfers (monthly pension or salary remittances), Wise and Revolut have strong Thailand offerings. Wise in particular has direct relationships with Thai banks for THB settlements and typically executes at or near the mid-market rate with a transparent fee.

FET Forms: Foreign Exchange Transaction Documentation

The Foreign Exchange Transaction (FET) form — issued by the Bank of Thailand and processed by the receiving bank — is a critical document for property buyers in Thailand.

Why FET forms matter for property purchase:

• Thailand's Land Code restricts foreign ownership of land (with exceptions for condominiums)
• Foreign nationals can own condominium units in buildings where foreigners collectively own no more than 49% of the floor area
• To register foreign ownership of a condo, you must demonstrate that the purchase funds were remitted from overseas in foreign currency
• The FET form (also referred to as a TT3 form historically) is issued by the Thai bank when it receives the foreign currency transfer, confirming the inward remittance
• This form is presented at the Land Department at the time of title deed transfer and is typically required by the developer as a condition of sale for foreign buyers

Practical steps:

1. Transfer the purchase amount from your overseas account to your Thai bank account via SWIFT
2. Ensure the purpose code in the SWIFT message references "property purchase" or equivalent
3. Request the FET form from your Thai bank upon receipt of funds
4. Keep the original FET form safe — it cannot easily be reissued and is required at registration

FET form requirements and procedures are subject to Bank of Thailand policy; verify current requirements with your bank and Thai property lawyer before transferring funds.

Maintaining UK Accounts Alongside Thai Accounts

Unlike some European countries, the UK does not have treaty-based reporting mechanisms that automatically complicate maintaining UK accounts while residing in Thailand. However:

• CRS applies: Thailand is a CRS participant, meaning Thai banks report accounts of foreign-resident customers to those customers' home tax authorities. If you are UK tax resident, your Thai accounts may be reported to HMRC
• UK bank retention: several UK high-street banks are willing to maintain accounts for UK nationals resident in Thailand, particularly if the account is long-standing. However, policies vary by institution and are subject to change — verify with your bank before relocating
• UK pension payments: many UK retirees in Thailand receive State Pension and private pension payments into UK accounts, then transfer to Thailand as needed. This is administratively straightforward and is a common strategy
• ISA retention: UK Individual Savings Accounts can generally be retained after leaving the UK, but no further contributions can be made once you are non-resident

Practical Tips for Thai Banking

1. Open your account at a major branch in Bangkok, Chiang Mai, Pattaya, or Phuket — international expat branches typically have English-speaking staff and familiarity with non-immigrant visa documentation
2. Use ATMs wisely: Thai banks charge foreign card holders a fixed ATM fee (typically THB 220 per withdrawal as of 2026). Use Wise or Revolut with a linked debit card to minimise this; alternatively, make larger, less frequent withdrawals
3. Promptbook-update your passbook regularly (if your account uses a passbook): some Thai banks still issue physical passbooks and may block older dormant accounts
4. Notify your bank before international transfers: a brief call or visit explaining the expected incoming transfer reduces the likelihood of AML freezes
5. Consider a bank with a dedicated expat desk: Bangkok Bank, Kasikorn, and SCB all have dedicated international customer services at flagship branches
