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
| Document | Notes |
|---|---|
| Passport (original + copy) | At least 6 months remaining validity |
| Visa page copy | Long-term visa is advantageous |
| Work permit | If applicable |
| Residence Certificate | Obtainable from Immigration or your embassy |
| Proof of Thai address | Rental contract, utility bill, etc. |
| Passport photo | Required by some banks |
| Minimum deposit | Typically 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.
| Item | Details |
|---|---|
| Registration requirements | Thai bank account + mobile number or passport number |
| Person-to-person transfers | Free for small amounts |
| Payments | Scan a QR code to pay |
| Availability for foreigners | Available 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
| Method | Features |
|---|---|
| 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.
| Item | Details |
|---|---|
| When required | Receiving transfers of USD 50,000 equivalent or more |
| Especially important for | Condominium purchase registration (FET is a required document) |
| Below USD 50,000 | A 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:
| Change | Details |
|---|---|
| Scope | Inbound remittances of USD 200,000 equivalent or more |
| New requirement | Banks must verify source-of-funds documentation |
| Previously | A verbal declaration of the fund source was sufficient |
| Stricter scrutiny for | Thai 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 Amount | Rule |
|---|---|
| Routine transfers | Statement of purpose required (tuition, medical expenses, living costs, etc.) |
| USD 50,000+ equivalent per day | Bank verifies supporting documents |
| Large transfers without clear purpose | Bank 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.
| Amount | Requirement |
|---|---|
| Under USD 20,000 | No declaration required |
| USD 20,000 or more | Customs declaration mandatory |
| Non-compliance | Risk of confiscation, fines, and criminal penalties |
When carrying multiple currencies, convert to USD at the BOT rate and add them together.
7. The Legal Significance of Holding a Thai Bank Account
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
| Point | Details |
|---|---|
| ① A long-term visa makes account opening possible | Policies vary by branch — if one turns you down, try another |
| ② Large transfers have rules | FET form for USD 50,000+; BOT’s new regulation requires document verification for USD 200,000+ |
| ③ CRS shares your Thai account information with Japan | Japanese 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.
