Introduction: why opening a bank account in Thailand has become more regulated in 2025
Foreign nationals who plan to live, invest, or work in Thailand must manage their finances in compliance with Thai laws and regulations. To open a bank account in Thailand is essential for daily transactions, salary deposits, international transfers, rent payments, and long-term investments. Since 2023, Thai banks have implemented stricter identification protocols, enhanced KYC procedures, and more rigorous AML screening. These changes follow updated guidance from the Bank of Thailand and increased enforcement by the Anti-Money Laundering Office (AMLO).
Due to these stricter standards, foreign nationals no longer have the flexibility they once did. In 2025, only those with long-term, verifiable immigration status can open a bank account in Thailand. Major banks do not accept tourist visas, visa exemptions, or DTV visas. Student visas (Non-ED) are still accepted with proper documentation from accredited institutions. However, requirements are now stricter. Applicants must show a stable connection to Thailand with comprehensive documentation and clear legal grounds for residence. This policy supports financial transparency and protects the banking sector from high-risk accounts.
Understanding this regulatory context is essential. Building on this, the article provides a comprehensive legal guide for foreign residents, retirees, workers, and investors on opening a bank account in Thailand. It then outlines accepted visa categories, required documentation, differences in bank policies, and practical tips for preparing an application. The analysis concludes with an examination of the latest banking practices implemented nationwide in 2025, now consistent across all major financial institutions.

The legal framework governing access to banking services to open a bank account in Thailand
Opening a bank account is not a mere administrative step. It is a legal process regulated by several statutes. The Anti-Money Laundering Act B.E. 2542 establishes the fundamental principles for identity verification, source-of-funds assessment, and risk classification. Banks must ensure that each customer presents a clear immigration status, verifiable identity, and reliable contact information. Compliance with this law is mandatory for all financial institutions.
The Financial Institutions Business Act B.E. 2551 completes this framework. It imposes detailed obligations on commercial banks, including customer due diligence, continuous account monitoring, and reporting requirements. Banks must identify the applicant’s immigration status and understand the purpose of opening an account. The Bank of Thailand clarifies that only foreigners with a long-term, legally recognised visa may satisfy these requirements.
Another important legal instrument is the Immigration Act B.E. 2522. Banks cannot accept applications from foreigners with temporary, short-term, or inconsistent immigration status. Because tourist entries are valid for a short period and are not associated with established residence in the Kingdom, the Banking sector cannot accept these immigration categories for account opening.
In addition, the Exchange Control Act regulates international transfers. When a foreigner opens a bank account to finance a property purchase, invest in a Thai company, or manage cross-border income, the bank may require additional documentation confirming the purpose of funds entering Thailand.
These legal obligations explain why banks must now reject applications from tourists and DTV visa holders without a stable long-term status. Their immigration status does not provide the long-term legal foundation needed to open a bank account in Thailand under the current regulations.
Which visas allow a foreigner to open a bank account in Thailand in 2025?
Only a limited number of visa categories are recognized by Thai banks as valid for account opening. These visas demonstrate a stable and legitimate connection to Thailand.
The Non-B visa with a valid work permit is the most widely accepted category. It provides clear evidence of legal employment, regular income, and long-term residence. Banks view this visa as a strong basis for account opening, as the applicant’s presence is supported by professional obligations and employer verification.
The Non-O marriage visa also allows a foreigner to open a bank account in Thailand, provided the foreigner can present a marriage certificate, identify a permanent address, and demonstrate a stable relationship with the Thai spouse. Banks usually welcome these applications due to the permanence of marriage-based residence.
Retirement visas—either Non-O or Non-O-A—are equally reliable. Retirees benefit from a formal immigration status. Retirement visas, either Non-O or Non-O-A, are also reliable. Retirees have formal immigration status, financial stability, and long-term residence. Banks accept these visas without difficulty, making them common for foreigners transferring pension funds or managing long-term finances. The digital work permit attached to some LTR categories further simplifies the process. Applicants under this visa enjoy simplified verification procedures and rapid approval.
Permanent residents also benefit from simplified procedures. Their status is equivalent to long-term settlement in Thailand and fully satisfies the legal requirements for identity verification.
Employees of BOI-promoted companies benefit from a digital work permit issued by the Ministry of Labour. This status is accepted as it guarantees a long-term presence under BOI supervision.
These visa categories represent the complete list of immigration statuses that allow a foreign national to open a bank account in Thailand in 2025.
Understanding Visa Requirements to open a bank account in Thailand
Foreign nationals with these visa types should understand why banks consistently refuse their account applications and what this means for their options.
The Regulatory Logic Behind Rejections
These refusals are not arbitrary or discriminatory. Thai banks operate under strict regulatory frameworks that require verifiable immigration stability for all foreign account holders. The underlying rationale is as follows:
Tourist visas and visa exemptions
These entries are for temporary stays, usually 30 to 60 days. They lack the permanence required by Anti-Money Laundering regulations. Banks cannot conduct reliable due diligence if the account holder may leave the country within weeks.
DTV (Destination Thailand Visa)
Although the DTV is valid for 180 days and targets remote workers, it is legally classified as a tourist category under Thai immigration law. Banks treat it identically to standard tourist visas in compliance assessments. As of January 2025, no major Thai bank has been observed accepting DTV holders for account opening in Thailand. This applies regardless of the applicant’s profile or financial strength. Some accredited Muay Thai gyms and cooking schools with established banking relationships may facilitate account opening for their DTV students through institutional guarantees. This service typically costs 3,000 to 5,000 THB and requires extensive documentation from the school. However, this remains an exception, not standard practice.
Non-ED visas
Non-ED student visas will remain accepted by major banks in 2025, provided the applicant presents a letter from their educational institution confirming enrollment. However, policies vary by branch, and some banks have become more selective, particularly in their preferences for language schools versus accredited universities. Students should contact their school in advance to obtain the required certification letter.

The documentation required to open a bank account in Thailand in 2025
Thai banks require a complete set of documents, including a valid passport with sufficient validity, a visa stamp for a recognized long-term visa, and a TM30 to confirm the applicant’s residence and immigration compliance. Proof of address, such as a lease agreement, a house registration document from the Thai spouse, or another legal document, is also required. Applicants with a Non-B visa must present their work permit or digital work permit. Those applying under a marriage visa need to provide their marriage certificate and identification of the Thai spouse. Applicants under the LTR visa must present their LTR approval letter.
Some banks may also request a Thai tax identification number, depending on the applicant’s financial profile. All submitted documents must have consistent information, especially regarding addresses or immigration dates, to prevent processing delays.
How the account opening process works when you open a bank account in Thailand
The process starts when the applicant visits a bank branch, where an officer reviews immigration documents and confirms visa eligibility. The officer verifies the TM30 and proof of address, and banks conduct identity checks using photographs and digital signatures. Applicants must state the purpose of opening the account in Thailand, as required by AML regulations. Once all verifications are complete, the account is opened, and mobile banking is activated. Branches in Bangkok, Phuket, and Chiang Mai are especially experienced in serving foreign clients and managing these procedures efficiently.
The banks most frequently used by foreigners to open a bank account in Thailand
Bangkok Bank has the most experience serving foreigners, with branches in all major cities and reliable international transfer services. Siam Commercial Bank (SCB) is known for modern digital tools and efficient mobile banking. Kasikorn Bank offers advanced online features but enforces stricter immigration policies. Krungsri Bank is popular among expatriates, especially Japanese and American nationals, for its customer service and product offerings. UOB Thailand is well-suited to high-net-worth individuals and LTR holders. While service quality and digital tools vary, visa requirements for account opening are now consistent across banks.
Many foreign clients engage a law firm when opening a bank account in Thailand, especially for investments, company formation, or long-term relocation. Legal assistance is valuable because banks assess more than visa type and TM30 compliance. They also review whether the client’s profile aligns with Thai regulatory expectations, particularly regarding tax residency, source of funds, and intended account use. For real estate purchases, company investments, or income from multiple jurisdictions, banks often request additional documents such as contracts, shareholding charts, or sale and purchase agreements.
A law firm can systematically organize supporting documents, anticipate compliance department inquiries, and ensure that information provided to the bank aligns with immigration and tax records. This coordination is essential, as inconsistencies between declarations to the bank, immigration authorities, and tax agencies may prompt further scrutiny or result in application refusal. Legal counsel can also clarify the long-term implications of using a Thai account to receive foreign income and assist clients in aligning their banking, immigration, and tax strategies. Consequently, opening a bank account in Thailand should be considered part of a comprehensive legal and financial planning process.
Conclusion
Opening a bank account in Thailand is a critical step for foreign nationals intending to live, work, or invest in the country. The process has become more regulated in 2025 due to enhanced AML and KYC requirements. Only those with long-term visas are eligible to open a bank account, while tourist visas, visa exemptions, and DTV visas are generally not accepted. Student visas (Non-ED) remain valid with appropriate documentation from accredited institutions, although requirements are now more stringent. By preparing the necessary documents, maintaining immigration compliance, and selecting an appropriate bank, foreign nationals can successfully complete the process and establish a secure financial foundation in Thailand. Understanding these requirements reduces the risk of application refusal and ensures a compliant banking experience.
