PHUKET, THAILAND – Foreign customers at Thailand’s largest banks have faced rising account maintenance fees and new verification demands in 2025, exposing thousands of expatriates to account deductions and closures.
Growing charges for dormant accounts
On 15 November 2025, 68‑year‑old retiree Axel Müller discovered that his Thai bank had deducted 75 Baht from his account over a three‑month stay in Germany. Banks imposed monthly inactivity fees of 25 Baht, even on small balances.
“I thought my account was safe,”
said Axel Müller, 68‑year‑old retiree.
Major institutions, including Bangkok Bank, Kasikorn Bank, and Siam Commercial Bank, currently charge between 25 and 50 Baht per month if balances fall below 2,000 Baht and no transactions occur for 6 to 12 months. The Bangkok Bank applies the highest fee of 50 Baht for accounts with less than 2,000 Baht.
Regulatory costs and digital transition
The Bank of Thailand enforced new compliance standards in 2023, forcing commercial banks to meet international anti‑money‑laundering rules. These measures pushed operational costs upward, leading banks to recover expenses from inactive accounts.
Thai institutions have spent millions of Baht expanding mobile banking platforms such as SCB Easy, K‑Plus, and Bangkok Bank Mobile, linking user activity directly with mobile‑based authentication. Customers who fail to log in or perform a transaction for an entire year often trigger inactivity status.
Expatriates hit hardest by new entry barriers
From July 2025, foreigners without Non‑Immigrant B, Non‑Immigrant O, or Thailand Privilege Visas faced tighter criteria to open new bank accounts. Tourists with temporary visas and passports were routinely rejected by major branches.
To open an account, banks now demand:
– A copy of a current Thai visa and passport
– Proof of residence such as a lease or Certificate of Residence
– A Thai mobile number for two‑factor authentication
– In some cases, a letter from the applicant’s embassy
Countries under special monitoring, including Iran, North Korea, Myanmar, Russia, and Belarus, must present additional documentation. Processing times for those cases extended beyond 30 business days at some branches.
How to avoid deductions
The Bangkok Bank confirmed that one transaction per 12‑month period maintains account activity. A small transfer of 10 Baht to another account, a debit card purchase, or a cash withdrawal can reset inactivity timers. Maintaining a minimum of 2,100 Baht also exempts holders from monthly deductions even after a year without full use.
For clients overseas, experts recommended scheduling automated domestic transfers between linked accounts every month. Alternately, customers could authorize a trusted representative in Thailand to perform occasional balance updates at a local branch.
Consequences of continued dormancy
If no movement occurs for 24 consecutive months, Thai banks possess authority to freeze or close accounts with balances below defined thresholds. Re‑opening or applying for a new account requires complete documentation under the 2025 KYC regime.
The loss of banking access can jeopardize Thai long‑term visas that legally require bank deposits of 800,000 Baht, or roughly €21,000. Without a valid Thai account, many retirees risk losing visa renewal eligibility.
Cross‑border reporting and taxation
Starting 2025, foreign tax agencies, including the German Federal Central Tax Office, automatically receive financial data under the OECD information exchange. All interest income from Thai deposits remains taxable in the holder’s home country.
International property investors must also present the Foreign Exchange Transaction Form (FET) to prove that real‑estate payments originate from abroad, ensuring compliance with Thailand’s foreign ownership law.
Fintech and digital alternatives
Online platforms such as Wise and Revolut offered partial solutions for outgoing transfers but could not satisfy immigration deposit or property purchase requirements. Thai immigration authorities still insist on formal local bank accounts for all retirees, business visa holders, and long‑stay foreign residents.
Future banking outlook
Financial analysts forecast that Thailand will continue aligning with Financial Action Task Force standards to stay off the FATF “grey list.” More rigorous client verification protocols and potential fee adjustments are expected by late 2026.
Simultaneously, usage of PromptPay, QR‑code payments, and digital wallets like TrueMoney and Line Pay grew nationwide by over 60% in 2025, reflecting a rapid transition toward fully cashless systems.
Key preventive measures for account holders
The article’s review of current fee schedules shows that clients can maintain compliance through five actions:
– Conduct at least one banking transaction every six months.
– Retain a balance above 2,000 Baht.
– Keep contact information, such as Thai phone number and email, updated.
– Log in to mobile banking apps regularly for automated activity records.
– Visit a local branch once per year to update passbooks and verification data.
As Thailand integrates international compliance norms into local practice, expatriates expecting traditional no‑fee accounts will need to adjust banking habits or risk automatic deductions and eventual closures by late 2025.
