Bank Investigation and Provisional Credit: Timeline and Reversals

When you dispute an electronic transfer, your bank’s investigation and provisional credit process runs on deadlines set by Regulation E: 10 business days to finish an initial review, or up to 45 days if the bank puts the disputed money back in your account while it keeps investigating. Longer windows apply to a few transaction types. The provisional credit is temporary, and if the bank ultimately finds no error, it can pull that money back out.

Reporting the Error and Starting the Clock

You have 60 days from the date the bank sent the statement showing the suspected error to notify the bank.¹ Most banks accept the notice by phone, through online or mobile banking, or by mail. Give your name and account number, describe what you believe went wrong, and provide as much detail as you can about the type, date, and amount involved.

Calling is the fastest way to start, but watch for one thing that trips people up. Your bank can require you to send a written confirmation within 10 business days after your call. If the bank tells you it requires that written confirmation and gives you an address, and you don’t follow through, it no longer has to give you provisional credit during the investigation.² The investigation still runs. You just lose the temporary money while it does.

Ask for a reference number or written acknowledgment when you file. That record fixes the date you reported the issue, which is what every deadline in the process runs from.

How Long the Investigation Can Take

Once the bank receives your notice, the baseline is 10 business days to investigate, decide, and report back. If the bank confirms an error, it must correct it within one business day of that determination.¹

Most investigations run past 10 business days. To take longer, the bank has to provisionally credit your account within those first 10 business days, which then buys it up to 45 days total from your notice to finish.³ The provisional credit is the price of the extension. One does not happen without the other.

Some situations get longer windows built in:

New accounts, meaning disputes arising within 30 days of your first deposit, give the bank 20 business days for the initial review and up to 90 days total.¹
International transfers can take up to 90 days total.¹
Point-of-sale debit card transactions can also take up to 90 days.¹

The point-of-sale rule is the one that catches people off guard. A disputed debit card purchase at a store or restaurant can take a full 90 days to resolve, even when the transaction was entirely domestic.

How Provisional Credit Works

Provisional credit is meant to keep you financially whole while the bank investigates. When the bank extends its investigation past 10 business days, it must credit your account for the full amount of the alleged error, including any interest that would have accrued.³ You have full access to those funds during the investigation.²

There is one narrow carve-out. If the bank has a reasonable basis for believing the transfer was unauthorized and has met the liability notice requirements, it can withhold up to $50 from the provisional credit.³ Many banks credit the full amount anyway, but the $50 withholding is legal.

Treat the money as temporary. If the investigation goes against you, the bank will take it back, and running your account balance down while it depends on provisional credit sets you up for overdrafts when the reversal hits.

What the Bank Must Tell You at the End

The bank must report its findings within three business days after completing the investigation.³ There are two possible outcomes.

If the bank confirms an error, the provisional credit becomes permanent and the case closes. The correction must happen within one business day of that determination.

If the bank finds no error, it must give you a written explanation and notify you that it will debit the provisional credit from your account. The written explanation must also tell you that you can request the documents the bank relied on.³ Those documents can include merchant receipts, transaction logs, or communications with the payment network. When you ask for them, the bank must provide copies in a form you can actually understand.⁴

When the Bank Reverses the Provisional Credit

Losing the provisional credit can knock your balance sideways if bills have already been paid from it. The regulation builds in a cushion. For five business days after the bank notifies you of the debit, it must honor checks and preauthorized transfers that were paid using those provisional funds, without charging overdraft fees for those items.³ Use that window to deposit other funds or rearrange automatic payments.

If the Bank Denies Your Dispute

A denial does not always end things. Start by requesting the investigation documents if you haven’t already. Reviewing the bank’s evidence sometimes reveals the investigator misunderstood the dispute or worked from incomplete records. If your original notice asked the bank to send documentation or clarify a transfer you didn’t recognize, and the bank’s response gives you new information showing an error actually occurred, you can reassert the error and the bank must investigate again.³

Outside that scenario, a bank that has fully completed the error resolution process has no obligation to reopen the case just because you disagree with the outcome. If you believe the bank itself broke the investigation rules, such as missing deadlines or failing to give provisional credit when it was required, you can file a complaint with the Consumer Financial Protection Bureau. The CFPB sends the complaint directly to the bank, which generally responds within 15 days.⁵ A complaint does not guarantee a reversal, but it puts regulatory pressure on the institution and creates an official record.

For larger amounts, a consumer protection attorney may be worth consulting. The Electronic Fund Transfer Act provides for actual damages, statutory damages up to $1,000 in individual actions, and attorney’s fees for successful claims. Banks that fail to follow the investigation procedures can face liability even if the underlying transaction turns out to have been legitimate.

Accounts and Transactions This Process Does Not Cover

These protections apply only to consumer accounts established for personal, family, or household purposes. Business and commercial accounts fall outside Regulation E entirely.⁶ Wire transfers are also excluded and run under a different legal framework, UCC Article 4A. And if the disputed charge ran through a credit card rather than pulling from your bank balance, the Fair Credit Billing Act and Regulation Z govern the process instead, with different rules and timelines.⁷

One thing that cannot narrow your rights: a payment app’s terms of service. No private agreement can waive a right created by the EFTA,⁸ so a platform’s policy that transfers are “final and irrevocable” does not change your bank’s obligation to investigate an unauthorized transfer claim.
