Recent media reports have highlighted cases in which individuals received multiple small, unexplained transfers from unknown persons and subsequently found their bank accounts designated as “warning accounts,” disrupting withdrawals, incoming payments, and everyday financial activities.
One of the biggest concerns for affected account holders is whether they must wait for prosecutors to issue a non-prosecution disposition—or even wait until lengthy criminal proceedings have concluded—before the restrictions can be removed.
Taiwan’s Criminal Investigation Bureau (CIB), National Police Agency, Ministry of the Interior, has publicly clarified that a non-prosecution disposition or final court judgment is not the only basis for removing a warning account designation.
Under certain special circumstances, an account holder may submit supporting documents to the competent police authority and request removal of the warning designation. If the circumstances are verified, the designation may be removed without necessarily waiting for the entire criminal proceeding to conclude.
For ordinary account holders, a warning account is often more than a banking inconvenience.
It may simultaneously involve a criminal investigation, explanations of financial transactions, preservation of evidence, and the protection of basic financial and living needs.
Fraud schemes have also become increasingly sophisticated. In addition to employment scams, loan scams, and investment scams, cases may involve malicious small-value transfers, triangular fraud schemes, identity theft, or unauthorized use of bank accounts.
As a result, even people who acted in good faith or had no knowledge of the underlying fraud may suddenly face account restrictions, police questioning, or allegations of aiding fraud or money laundering.
This article explains the legal framework governing warning accounts, the CIB’s recent clarification, five situations in which early removal may be available, and the steps account holders should take to protect themselves.
1. What Is a Warning Account, and Why Can a Bank Account Suddenly Be Restricted?
Under Taiwan’s regulations governing deposit accounts and suspected illegal or apparently abnormal transactions, a warning account generally refers to a deposit account that has been reported to a financial institution by a court, prosecutors office, or judicial police authority because of the needs of a criminal investigation.
In other words, a warning account designation is generally connected to a criminal investigation and a notification from a judicial or law enforcement authority, rather than being merely a unilateral decision by the bank.
Once a deposit account is designated as a warning account, the bank may suspend transactions involving that account, and incoming transfers may be returned to the remitting bank depending on the applicable rules and circumstances.
Other deposit accounts held by the same person may also become subject to related controls. Functions such as ATM withdrawals, telephone banking transfers, online banking transfers, and other electronic payment services may consequently be restricted.
The practical impact can be significant, potentially affecting salary deposits, rent payments, automatic credit card payments, access to living expenses, and business transactions.
It is also important to note that multiple small incoming or outgoing transactions may, in some circumstances, resemble activity intended to test whether an account remains operational.
This helps explain why an account holder with no knowledge of criminal activity may nevertheless become subject to risk-control measures when unusual transaction patterns appear.
However, the existence of unusual transactions does not, by itself, establish that the account holder knowingly participated in fraud or money laundering.
2. CIB Clarification: Non-Prosecution Is Not the Only Way to Remove a Warning Account Designation
A common misconception is that once a bank account has been designated as a warning account, the account holder must wait until prosecutors issue a non-prosecution disposition, a court enters a judgment of acquittal, or the criminal case otherwise reaches a final conclusion before seeking removal of the designation.
That understanding is incomplete.
According to the CIB’s public clarification, the current warning account relief mechanism provides greater flexibility in certain circumstances.
In addition to removal based on qualifying judicial or prosecutorial documents, an account holder who falls within certain specified circumstances may submit communications, transaction records, and other supporting evidence to the competent police authority and request removal of the warning designation.
If the police verify the circumstances, the warning account designation may be removed in accordance with the applicable procedures.
Therefore, if an account holder becomes involved because of malicious transfers, a commercial dispute, a triangular fraud scheme, unauthorized account use, or an administrative error, it is important to promptly determine whether the case may qualify for early removal of the warning designation.
Rather than simply waiting for the criminal investigation to end, the account holder should begin organizing relevant evidence, including:
■ transaction records;
■ communications;
■ purchase or sales records;
■ payment documentation;
■ police reports; and
■ other evidence explaining the source and purpose of the disputed funds.
The earlier the transaction history and supporting evidence are organized, the stronger the account holder’s position may be when explaining that they did not knowingly provide their account for use by a fraud organization.
3. Five Situations Where You May Apply for Early Removal of a Warning Account Designation
According to the CIB’s public clarification, certain special circumstances may allow an account holder to submit supporting materials and request removal of a warning account designation.
A common feature of these situations is that although suspicious funds may have passed through the account, the account holder may not have participated in the fraud scheme or intentionally provided the account for criminal use.
1. Ordinary Commercial Disputes
The first situation involves an ordinary commercial or transaction dispute.
➡︎ For example, a disagreement may arise between a buyer and seller concerning defective goods, refunds, contractual performance, or another commercial issue. If one party reports the matter to the police, the recipient’s account may become associated with the reported transaction and subsequently be designated as a warning account.
Relevant evidence may include:
■ purchase orders;
■ invoices;
■ bank transfer records;
■ shipping records; and
■ communications between the parties.
These materials may help establish that the disputed funds arose from an ordinary civil or commercial transaction rather than from fraudulent activity.
2. Triangular Fraud Schemes
A triangular fraud scheme typically involves a fraudster deceiving both a buyer and an innocent seller.
➡︎ For example, the buyer may believe that they are purchasing goods from the fraudster, while the fraudster instructs the buyer to transfer payment directly to an innocent third-party seller.
The seller then receives funds originating from a fraud victim and may consequently be mistaken for a recipient of fraud proceeds.
In such a case, the account holder should preserve:
■ platform transaction records;
■ buyer-seller communications;
■ logistics records;
■ proof of delivery; and
■ information explaining the source of the transfer.
These materials can help reconstruct the complete transaction and demonstrate why the account received the funds.
3. Malicious Transfers or Retaliation by Fraudsters
Another situation involves deliberate retaliation or harassment by fraudsters.
For example, an account may receive repeated small transfers after the account holder refuses to cooperate with suspicious requests, or someone may deliberately abnormal transaction activity in an attempt to cause the account to be flagged.
Potential evidence may include:
■ records of unusual incoming transfers;
■ police reports;
■ communications with suspicious individuals;
■ threatening messages; and
■ records showing that the account holder blocked or refused further contact.
Such evidence may help establish that the unusual transactions were deliberately created by a third party rather than initiated or authorized by the account holder.
4. Unauthorized or Fraudulent Use of a Bank Account
A warning account designation may also result from unauthorized use of an account or identity theft.
For example, another person may unlawfully obtain or use the account holder’s:
■ bank account information;
■ online banking credentials;
■ mobile phone number;
■ personal identification information; or
■ authentication credentials.
If this occurs, the account holder should promptly contact the bank to suspend or secure the relevant services and preserve evidence such as police reports, unusual login records, bank notifications, and documents showing unauthorized access or subsequent corrective action.
5. Administrative or Data-Entry Errors
A warning account designation may sometimes result from an administrative or clerical error.
Examples may include:
■ incorrect reporting information;
■ an incorrectly entered account number;
■ mistaken identity involving individuals with similar names; or
■ other administrative errors.
Relevant evidence may include bank notices, case information, correction requests, identification documents, and other materials demonstrating the error.
Whether early removal is granted depends on more than the account holder’s verbal explanation.
The supporting evidence must sufficiently explain why the abnormal transactions occurred and why the account holder should not be treated as someone who knowingly provided an account for criminal activity.
Communications, transaction records, logistics documents, bank statements, police reports, platform complaint records, bank notices, and evidence of the account holder’s immediate response to the suspicious activity may all be relevant.
4. Where Should You Apply, and What Documents Should You Prepare?
The Criminal Investigation Bureau provides an application form for members of the public seeking removal of a warning account designation.
Applicants should review the applicable requirements and instructions regarding supporting documents and submit the application to the police authority responsible for the relevant case.
Depending on the applicable procedure, the applicant may need to prepare the required copies of the application form, identification documents, and supporting materials establishing the grounds for removal.
Before submitting an application, the account holder should first contact the bank to clarify:
■ the reason for the warning designation;
■ the original reporting authority;
■ relevant case information; and
■ which accounts are currently affected.
Relying solely on a brief oral explanation without confirming whether a police report or investigation case number already exists may make it difficult to prepare the appropriate supporting materials.
Once the relevant case information has been identified, communications, transfer records, transaction documents, police reports, and other objective evidence should be organized systematically.
The explanation submitted in support of removal should be consistent with the objective evidence.
An account holder who is anxious to restore access to their account should not invent, exaggerate, or casually the factual explanation.
Inconsistent statements made to different authorities may additional concerns during a criminal investigation.
If the matter already involves suspected fraud, money laundering, or a police summons for questioning, obtaining legal advice before making a formal statement may help reduce the risk of inaccurate or unnecessarily adverse statements.
5. Can You Still Access Funds for Daily Living Before the Restriction Is Removed?
The CIB has also clarified that an account holder who does not yet qualify for one of the special grounds for early removal is not necessarily prevented from accessing all of their funds.
If the person has other financial accounts that have not themselves been designated as warning accounts, certain transactions may still be available through in-person banking procedures, depending on the restrictions applicable to those accounts.
This distinction can be extremely important.
Many people panic after receiving notice that one of their accounts has been designated as a warning account and assume that every account and all of their funds have become completely inaccessible.
In practice, a warning account and other related controlled accounts may be subject to different restrictions.
The account holder should therefore confirm the status of each account directly with the relevant financial institution while also contacting the original reporting authority to determine why the restriction was imposed.
If the restrictions significantly affect salary payments, rent, medical expenses, or other essential living costs, relevant documentation should also be preserved.
These materials may be useful when communicating with financial institutions or authorities or when pursuing available administrative or legal remedies.
6. Why a Warning Account Case Is More Than Just a Banking Issue
The most significant risk in a warning account case is that the underlying financial transactions may be connected to allegations of fraud, money laundering, or the provision of an account for criminal use.
Therefore, the issue is not simply:
“When will my bank account be unfrozen?”
The account holder should also consider whether the underlying circumstances could result in a criminal investigation or criminal liability.
Important questions may include:
■ Did you provide a bank account, debit card, online banking credentials, mobile verification code, or cryptocurrency account to another person?
■ Were you persuaded to provide account information through an employment, loan, investment, payment-collection, or account-rental scheme?
■ Can you explain the purpose and source of each disputed deposit, transfer, or withdrawal?
■ Has a fraud victim already filed a police report involving funds transferred to your account?
■ Have you received a summons from the police or prosecutors?
■ What evidence supports your explanation of how the account was used?
In a criminal case, simply stating “I didn’t know” does not automatically resolve the issue.
Investigators may evaluate the account holder’s knowledge and intent based on the totality of the circumstances, including:
■ the account holder’s background and experience;
■ the reason the account information was provided;
■ whether compensation was received;
■ whether the other party’s explanation was obviously suspicious;
■ whether the transactions were abnormal; and
■ whether the account holder promptly contacted the bank or police after discovering the problem.
Accordingly, when a warning account designation is accompanied by a police summons, the criminal investigation and the account-removal procedure should be addressed together rather than treated as completely separate matters.
7. Chien Sheng’s Advice: Three Things to Do Immediately
After discovering that a bank account has been flagged, one of the most damaging responses is to provide fragmented explanations while failing to preserve evidence—or, worse, to delete communications or repeatedly change the account of what happened.
Chien Sheng International Law Firm recommends focusing on three immediate steps.
1. Preserve All Relevant Evidence
Immediately preserve:
■ bank statements and transaction records;
■ transfer notifications;
■ text messages;
■ call records;
■ LINE and social media communications;
■ transaction-platform records;
■ logistics records; and
■ police reports.
Do not delete suspicious conversations simply because they appear unfavorable. The complete conversation may help establish how the transaction arose and what the account holder actually understood at the time.
2. Confirm the Reason for the Restriction
Contact the bank as soon as possible to determine why the account has been restricted and to identify the original reporting authority and relevant case information.
This information is essential for determining the appropriate procedure and the evidence that may be required.
3. Address Any Criminal Investigation at the Same Time
If the matter already involves allegations of fraud, money laundering, or a police summons, consider obtaining advice from a criminal defense attorney before providing detailed statements.
Counsel can help assess whether the case may qualify for early removal of the warning account designation while simultaneously preparing a defense strategy for the criminal investigation.
➡︎ If you discover unfamiliar small-value transfers, do not immediately withdraw or transfer the unexplained funds. Contact the bank, report the suspicious activity where appropriate, and preserve the transaction records.
➡︎ If you receive a police summons, first determine what the case concerns and organize the relevant evidence rather than attending questioning without understanding the underlying transactions.
➡︎ If fraudsters threaten or retaliate against you, preserve screenshots and other records instead of deleting the communications.
➡︎ If the matter arises from a commercial dispute, prepare purchase orders, delivery records, refund information, communications, and other materials showing the actual nature of the transaction.
➡︎ If the account was used without authorization, contact the bank promptly, report the incident, preserve login and transaction records, and pursue the appropriate correction or removal procedures.
8. Conclusion: A Warning Account Designation Can Be Challenged, but Evidence Is Essential
The CIB’s clarification is significant because it emphasizes that a warning account designation does not necessarily mean that the account holder must passively wait for a non-prosecution disposition or final court judgment.
Where the case involves circumstances such as an ordinary commercial dispute, a triangular fraud scheme, malicious retaliation or transfers by fraudsters, unauthorized account use, or an administrative or data-entry error, the account holder may be able to submit supporting evidence and seek early removal of the warning designation.
However, removing the warning account designation and resolving potential criminal liability are related but distinct issues.
Successful removal of the warning designation does not necessarily mean that every aspect of the criminal investigation has ended.Conversely, the fact that the warning designation cannot yet be removed does not, by itself, establish that the account holder committed a crime.
The central questions are whether the account holder can explain the source of the funds, how the account was used, the nature of the underlying transactions, and whether there is evidence establishing the knowledge or intent required for fraud or money laundering liability.
