Under Regulation E, a financial institution generally has 10 business days to investigate a reported electronic fund transfer (EFT) error. If the bank or credit union cannot complete its investigation within this 10-business-day window, it must provide a provisional credit to the consumer's account for the amount of the alleged error. This credit allows the consumer to use the funds while the institution takes additional time--up to 45 calendar days in most cases--to finalize the investigation. If the institution determines no error occurred, it may reverse the credit after providing proper notice.

What Controls the Issue

The primary authority governing these timelines is Regulation E (12 CFR § 1005.11), which implements the federal Electronic Fund Transfer Act (EFTA). These rules apply to transactions involving consumer asset accounts, such as checking and savings accounts, and cover payment rails like debit cards, ACH transfers, and automated teller machine (ATM) transactions.

The Consumer Financial Protection Bureau (CFPB) is the lead regulator for these protections. It is important to distinguish these rights from Regulation Z, which governs credit card disputes. Regulation E does not apply to credit card billing errors, nor does it automatically incorporate private "Zero Liability" marketing policies from card networks like Visa or Mastercard, which may offer additional protections but do not override federal law.

The Regulation E Investigation Timeline

The resolution process follows a strict sequence of deadlines. Failure by the financial institution to meet these deadlines can result in legal liability and statutory damages.

Action Item Deadline Notes
Consumer Reports Error 60 calendar days From the date the periodic statement was sent.
Initial Investigation 10 business days The bank must determine if an error occurred.
Provisional Credit 10 business days Required if the investigation is not finished.
Written Confirmation 10 business days The bank may require this to grant provisional credit.
Standard Resolution 45 calendar days Total time allowed if provisional credit is issued.
Extended Resolution 90 calendar days For new accounts, POS, or foreign transactions.

Requirements for Provisional Credit

Provisional credit is not a final refund; it is a temporary placeholder. To ensure you receive it, you must meet specific criteria defined by the FDIC Consumer Compliance Manual:

Exceptions and Extended Timelines

Certain types of transactions allow financial institutions more time to investigate before they are required to provide credit or reach a final decision. According to NCUA guidance, the following extensions apply:

  1. New Accounts: If the account was opened within 30 days of the transaction, the initial investigation window is extended to 20 business days, and the total investigation can take up to 90 calendar days.
  2. Point-of-Sale (POS) Transactions: Transactions made at a merchant terminal (debit card purchases) allow for a 90-calendar-day investigation period.
  3. Foreign Transactions: Transfers initiated outside the United States also qualify for the 90-calendar-day extension.

FAQ

Can the bank take the provisional credit back? Yes. If the bank's investigation concludes that no error occurred, they can "re-debit" your account. However, they must notify you of the date and amount of the reversal and continue to honor checks or preauthorized transfers to third parties for five business days after the notification, but only for the amount of the reversed credit.

Does provisional credit apply to Zelle or Venmo? Regulation E applies to P2P transfers if they are linked to a consumer's bank account. However, the "error" must typically be an unauthorized transfer or a technical mistake. Voluntary payments made to scammers (where you authorized the transfer but were deceived) are often treated differently by banks, though CFPB guidance continues to evolve in this area.

What if the bank misses the 10-day deadline? If the bank fails to provide provisional credit and does not finish the investigation within 10 business days, they are in violation of Regulation E. You can escalate the issue by filing a complaint with the CFPB or the National Credit Union Administration (NCUA) for credit union accounts.
