Opening a Bank Account in Thailand | Remittance Rules, QR Payments, and Foreign Exchange Regulations You Need to Know

A practical guide for expats, accompanying families, students, and retirees living in Thailand: how to open a bank account, rules for sending and receiving money, PromptPay QR payments, and key foreign exchange regulations updated for 2026.

This is Part 8 of the Thai Life and Law series. In Part 7, we covered children’s education and school options. This time, we look at banking, remittances, and foreign exchange regulations. In Thailand, QR code payments have become part of daily life — from street vendors to convenience stores. Without a bank account, everyday life is inconvenient. Let’s walk through how to open an account, the rules for sending and receiving money, and the foreign exchange regulations you should know about.


1. You Cannot Get By Without a Bank Account

QR code payments through PromptPay have become the norm in Thailand. Rent, utility bills, online shopping, taxi fares, street food — nearly everything can be paid by scanning a QR code.

Without a Thai bank account, you would need to carry cash for every transaction or rely on a Japanese credit card. ATM withdrawal fees (around 220 THB per transaction) add up quickly. Opening a bank account is one of the first steps to settling into life in Thailand.


2. Opening an Account — Which Bank? What Do You Need?

Foreigners Can Open Accounts

Foreigners can open bank accounts in Thailand. However, holding a long-term visa (Non-B, Non-O, Non-ED, LTR, etc.) makes the process significantly easier. Some branches accept applications from tourists, but policies vary widely between banks and even between branches of the same bank.

Since 2025, banks have been tightening their screening processes in response to enhanced Anti-Money Laundering Act (AMLA) compliance requirements. It is not uncommon to be turned away at one branch and successfully open an account at another.

Typical Required Documents

DocumentNotes
Passport (original + copy)At least 6 months remaining validity
Visa page copyLong-term visa is advantageous
Work permitIf applicable
Residence CertificateObtainable from Immigration or your embassy
Proof of Thai addressRental contract, utility bill, etc.
Passport photoRequired by some banks
Minimum depositTypically 500–1,000 THB

Bank Characteristics

Specific policies differ by branch, but general tendencies are as follows:

  • Kasikorn Bank (KBank) — Generally considered more flexible with foreign customers
  • Bangkok Bank — Historically strong in serving foreigners, though screening has tightened in recent years
  • Krungsri (Bank of Ayudhya) — Offers savings accounts for foreign nationals

Online account opening is generally not available for foreigners. You will need to visit a branch in person.


3. PromptPay — Thailand’s QR Payment System

How It Works

PromptPay is an instant payment and transfer system led by the Bank of Thailand (BOT). It links your bank account to your mobile phone number or passport number. The Payment Systems Act B.E. 2560 (2017) provides the legal framework.

ItemDetails
Registration requirementsThai bank account + mobile number or passport number
Person-to-person transfersFree for small amounts
PaymentsScan a QR code to pay
Availability for foreignersAvailable with a Thai bank account

Foreigners Can Use It

Foreigners with a Thai bank account can register for PromptPay using their passport number — a Thai national ID is not required. Registration can be done through mobile banking apps or at a bank branch.

Registering for PromptPay at the same time you open your account means you can start making QR payments immediately.


4. Receiving Money from Abroad — How Does It Work?

Transfer Methods

MethodFeatures
SWIFT transfer (bank-to-bank)Most common. Requires the Thai bank’s SWIFT code, account number, and beneficiary name
Fintech services (Wise, DeeMoney, etc.)Often cheaper than banks. Only services licensed by the BOT are legal

For large amounts, bank transfers tend to be safer. When using fintech services, verify that the provider holds a BOT licence.

FET Form — Required for Transfers of USD 50,000 or More

When receiving a foreign currency transfer of USD 50,000 equivalent or more in Thailand, you must obtain an FET (Foreign Exchange Transaction) form from the bank.

ItemDetails
When requiredReceiving transfers of USD 50,000 equivalent or more
Especially important forCondominium purchase registration (FET is a required document)
Below USD 50,000A bank Credit Advice can serve as an alternative

If you are considering purchasing a condominium, make sure to obtain the FET form when transferring the purchase funds. It will also be needed when repatriating funds upon sale. (See Part 3: Can Foreigners Buy or Rent Property in Thailand? for details.)

BOT’s New Regulation — Document Verification for USD 200,000+

The BOT issued Circular No. 8434/2568 (dated 29 December 2025), tightening remittance regulations:

ChangeDetails
ScopeInbound remittances of USD 200,000 equivalent or more
New requirementBanks must verify source-of-funds documentation
PreviouslyA verbal declaration of the fund source was sufficient
Stricter scrutiny forThai real estate investment, digital assets/cryptocurrency, other capital transfers

If you are transferring large amounts to Thailand — such as retirement payouts, property sale proceeds, or investment funds — you will need to prepare documentation proving the source of funds (employment certificate, retirement certificate, sale contract, etc.).


5. Sending Money Out of Thailand — You Need a Stated Purpose

A Reason Is Required

Outbound remittances from Thailand are regulated under the Exchange Control Act B.E. 2485 (1942).

Transfer AmountRule
Routine transfersStatement of purpose required (tuition, medical expenses, living costs, etc.)
USD 50,000+ equivalent per dayBank verifies supporting documents
Large transfers without clear purposeBank may decline the transaction

If you plan to transfer remaining funds from your Thai account back to Japan when leaving the country, you will need documentation proving the purpose (employment certificate, resignation letter, etc.). Prepare these before your departure.

AMLA Automatic Reporting

Under the Anti-Money Laundering Act B.E. 2542 (1999), cash transactions of 2 million THB or more are automatically reported by financial institutions to AMLO (Anti-Money Laundering Office). Suspicious transactions are reported regardless of amount.

This does not mean the transaction is treated as criminal — it is a legal reporting obligation. Legitimate transfers proceed without issue.


6. Rules for Bringing Cash into Thailand

If you bring cash equivalent to USD 20,000 or more in foreign currency into Thailand, you are required to declare it to Customs. The same rule applies when leaving the country.

AmountRequirement
Under USD 20,000No declaration required
USD 20,000 or moreCustoms declaration mandatory
Non-complianceRisk of confiscation, fines, and criminal penalties

When carrying multiple currencies, convert to USD at the BOT rate and add them together.


Visa Renewal Requirement

Renewing an O-A visa (retirement) requires a Thai bank account balance of at least 800,000 THB (or monthly income of at least 65,000 THB). The deposit must have been in place for at least 2 months before the application. The 800,000 THB balance must be maintained for 3 months after the visa is granted.

CRS — Your Account Information Is Shared with Japanese Tax Authorities

Thailand participates in the CRS (Common Reporting Standard) and began automatic exchange of financial account information in 2023. This means that information about your Thai bank accounts is shared with the Japanese tax authorities.

If you hold significant funds in a Thai account or earn income abroad, you need to file tax returns appropriately in both Japan and Thailand. (See Part 4: Do You Need to File Taxes in Thailand? for details.)


8. Summary — Three Key Points

PointDetails
① A long-term visa makes account opening possiblePolicies vary by branch — if one turns you down, try another
② Large transfers have rulesFET form for USD 50,000+; BOT’s new regulation requires document verification for USD 200,000+
③ CRS shares your Thai account information with JapanJapanese tax authorities can see your Thai accounts. File your taxes properly in both countries

Thailand’s financial environment has become remarkably convenient with the spread of QR payments. At the same time, foreign exchange controls and anti-money laundering measures mean that moving large sums involves rules and documentation. Understanding these rules from the outset will help you manage your finances in Thailand with confidence.
