Provisional Credit Under Regulation E Runs on Business Days, Not Calendar Days

Two units of time inside one section

One section of Regulation E holds both kinds of deadline at once. Under 12 CFR 1005.11, a financial institution that receives a notice of error "shall determine whether an error occurred within 10 business days of receiving a notice of error." A few lines later, the same section says an institution that cannot finish in time "may take up to 45 days from receipt of a notice of error to investigate and determine whether an error occurred" — but only if it meets four conditions, starting with a provisional credit.

Ten business days and forty-five days are not measured with the same ruler. One is counted in days the institution is open; the other on the wall calendar, weekends and closures included. The numbers stay fixed, but the dates they land on move, sometimes by most of a week. The governing text is in the Electronic Code of Federal Regulations, 12 CFR 1005.11 Procedures for Resolving Errors.

What a business day is, and who decides

Regulation E does not point to a federal holiday schedule. Under 12 CFR 1005.2(d), a business day means "any day on which the offices of the consumer's financial institution are open to the public for carrying on substantially all business functions." The count is therefore institution-specific: a bank open Monday through Friday and a credit union that also opens Saturday morning may not reach the same tenth business day. Calendar-day limits in the same section are untouched. Definitions are in the Electronic Code of Federal Regulations, 12 CFR 1005.2 Definitions.

Holiday dates below come from the U.S. Office of Personnel Management, Federal Holidays Schedule, which lists Veterans Day 2026 as Wednesday, November 11 and Thanksgiving Day 2026 as Thursday, November 26. A private institution is not bound by that schedule, so treat the closures as an assumption.

The door into the process closes on calendar days

Before any investigation clock starts there is an entry condition, counted the other way around. Section 1005.11(b)(1)(i) requires the notice of error to reach the institution no later than 60 days after it sends the periodic statement or provides the passbook documentation on which the alleged error is first reflected. Sixty days, not sixty business days, running from the sending of the statement rather than the transaction date.

A second 60-day count sits in a different section. Section 1005.6(b)(3) provides that "A consumer must report an unauthorized electronic fund transfer that appears on a periodic statement within 60 days" of the institution's transmittal of that statement, in order to avoid liability for transfers occurring afterward. The two can expire together, but one asks whether the institution must investigate and the other how much of a loss the consumer bears. Both are in the Electronic Code of Federal Regulations, 12 CFR 1005.6 Liability of Consumer for Unauthorized Transfers.

Those tiers are themselves a calculation. With timely notice after a loss or theft of an access device, liability is capped at "the lesser of $50" or the transfers occurring before notice. Without it, the cap becomes "the lesser of $500 or the sum of" two components, and the larger figure applies only where the institution establishes the later transfers would not have occurred had notice come inside the two-business-day window. Paragraph (b)(4) provides that where the delay was due to extenuating circumstances, the institution "shall extend the times" above to a reasonable period.

Ten business days to decide, three to report

The base path in 1005.11(c)(1) has two sequential segments. The determination is due within 10 business days of receiving the notice. The report of results is due within three business days after the investigation is completed — a clock running from completion, not from the deadline.

Paragraph (b)(2) lets an institution require written confirmation of an oral notice within 10 business days, with a limit. The official commentary published by the Consumer Financial Protection Bureau, Regulation E Section 1005.11 with Official Interpretations states that an institution "must begin its investigation promptly upon receipt of an oral notice" and "may not delay until it has received a written confirmation." The same commentary notes a notice of error is effective even where it omits the account number, if the institution can identify the account.

Forty-five days is bought, not granted

Section 1005.11(c)(2) attaches four obligations to the longer route, all measured in business days. The institution (i) "Provisionally credits the consumer's account in the amount of the alleged error (including interest where applicable)" within 10 business days of receiving the notice; (ii) "Informs the consumer, within two business days after the provisional crediting" of the amount and date of that credit, and gives full use of the funds during the investigation; (iii) "Corrects the error, if any, within one business day after determining that an error occurred"; and (iv) "Reports the results to the consumer within three business days after completing its investigation."

Two exceptions sit inside (c)(2)(i). The institution need not provisionally credit where it "requires but does not receive written confirmation" within 10 business days of an oral notice, or where "The alleged error involves an account that is subject to Regulation T of the Board of Governors." Outside those branches, the 45-day path and provisional credit travel together.

The statutory floor is 15 U.S.C. 1693f, which directs an institution taking the longer route to "within ten business days after receiving such notice provisionally recredit the consumer's account," and provides that "Such investigation shall be concluded not later than forty-five days after receipt of notice," as published by the U.S. Government Publishing Office, 15 U.S.C. 1693f Error Resolution.

Two substitutions that change the arithmetic

Paragraph (c)(3) swaps numbers into the base rule rather than rewriting it. Under (c)(3)(i), "The applicable time is 20 business days in place of 10 business days" where the notice involves a transfer to or from the account within 30 days after the first deposit to the account was made. Under (c)(3)(ii), "The applicable time is 90 days in place of 45 days" for a notice involving a transfer that (A) "Was not initiated within a state," (B) "Resulted from a point-of-sale debit card transaction," or (C) "Occurred within 30 days after the first deposit to the account was made."

Doubling 10 business days to 20 doubles a count that already absorbs weekends, so how much calendar distance the substitution buys depends on the closures inside the longer window. Doubling 45 days to 90 moves a fixed distance. A new account that also produced a point-of-sale dispute can sit in both at once.

A worked calendar, November 2026

Assume a periodic statement sent Friday, October 9, 2026, and an institution open Monday through Friday, closed weekends and the federal holidays above. Business days below are counted from the first business day after receipt, a convention this example assumes, since the section sets each period's length without fixing which day the count starts. A notice of error reaches it on Monday, November 9, 2026. The 60-day entry window from that statement runs to Tuesday, December 8, 2026, so the notice arrives with a month to spare.

Counting business days from November 9, with Veterans Day on Wednesday, November 11 removed, the tenth business day is Tuesday, November 24, 2026 — 15 calendar days after the notice. Had the institution been open every weekday with no closure, the tenth business day would have been Monday, November 23. One closure moved the deadline by a day; the two intervening weekends moved it by four more.

If the institution takes the 45-day path and posts the provisional credit on November 24, the two-business-day notice under (c)(2)(ii) is due by Friday, November 27, 2026, because Thanksgiving Day on Thursday, November 26 is not counted. Two business days spanned three calendar days.

The 45-day outer limit lands on Thursday, December 24, 2026. If the investigation closes that day, the three-business-day report under (c)(2)(iv) is due Wednesday, December 30, 2026, with Christmas Day on Friday, December 25 removed. That sits six calendar days past the 45-day deadline — a common confusion, since 45 days caps the investigation while a separate business-day count governs the report. On the new-account substitution, the twentieth business day from November 9 is Wednesday, December 9, 2026 — 30 calendar days out. The 90-day substitution reaches Sunday, February 7, 2027.

Reading the two counts side by side

Converting each deadline into calendar days from the same notice makes the split visible. Ten business days consumed 15 calendar days here; twenty consumed 30. The 45-day and 90-day limits consumed what they say, because closures do not touch them.

When a provisional credit is taken back

A provisional credit is not a settlement. If the investigation concludes that no error occurred, the institution may debit the credited amount, and paragraph (d)(2) attaches two obligations. The institution must "Notify the consumer of the date and amount of the debiting," and must notify the consumer that it "will honor checks, drafts, or similar instruments payable to third parties" and preauthorized transfers for five business days after that notification, without an overdraft charge caused by the reversal. The same subparagraph adds that the institution "need honor only items that it would have paid if the provisionally credited funds had not been debited." In the worked example, a reversal notice issued Wednesday, December 30, 2026 would carry that protection through Thursday, January 7, 2027, once the New Year's Day closure on Friday, January 1 is removed.

Paragraph (d)(1) requires the report of results to include a written explanation of the findings, and the consumer may request the documents relied on. Paragraph (e) closes the loop for an institution that has fully complied: no further responsibility under the section if the consumer later reasserts the same error, except where the error is asserted after the consumer receives information provided under paragraph (a)(1)(vii).

Credit cards run a different clock

Debit card and credit card disputes are governed by different regulations, and reading one schedule into the other produces wrong dates. Regulation Z handles billing errors in 12 CFR 1026.13. The notice must be received "no later than 60 days after the creditor transmitted the first periodic statement" reflecting the alleged error. The creditor must acknowledge in writing within 30 days, unless it has already completed the resolution procedures inside that time, and must complete resolution "within 2 complete billing cycles (but in no event later than 90 days)."

Two complete billing cycles is a third unit of time, tied to the statement schedule rather than to the calendar or to open days. While the dispute is pending, 1026.13(d)(1) provides that "The consumer need not pay (and the creditor may not try to collect) any portion of any required payment that the consumer believes is related to the disputed amount." The text is in the Electronic Code of Federal Regulations, 12 CFR 1026.13 Billing Error Resolution.

Numbers to Re-check

The institution's own open days. The business-day count turns on when offices are open for substantially all business functions, so the tenth business day is a fact about one institution, not a national date.

Which 60-day count is in play. Section 1005.11(b)(1)(i) runs from the sending of the periodic statement, 1005.6(b)(3) from transmittal, and 1026.13(b)(1) from transmittal of the first statement reflecting the error.

Whether a substitution applies. The 20-business-day substitution turns only on whether the transfer was to or from the account within 30 days after the first deposit; the 90-day substitution turns on that condition, or on whether the transfer was not initiated within a state, or resulted from a point-of-sale debit card transaction.

Account type. Prepaid accounts carry modified rules under 12 CFR 1005.18, and payroll card and government benefit accounts have their own provisions in the part.

Dollar figures in 1005.6. The $50 and $500 caps appear in the regulation as fixed dollar amounts, so read them from the current section text.

Where This Doesn't Apply

The schedule above governs a narrow class of disputes. Several common situations sit outside it.

Transfers the consumer authorized. Section 1005.2(m) defines an unauthorized electronic fund transfer as one "initiated by a person other than the consumer without actual authority to initiate the transfer and from which the consumer receives no benefit," and excludes three categories: transfers by a person the consumer furnished the access device to, unless the institution has been told those transfers are no longer authorized; transfers made with fraudulent intent by the consumer or someone acting in concert; and transfers initiated by the institution or its employee. A transfer the consumer was induced to send may fall outside the definition even where the loss is real.

Prepaid accounts before identity verification. Under 12 CFR 1005.18(e)(3)(i), "For prepaid accounts that are not payroll card accounts or government benefit accounts," an institution is not required to comply with the liability limits and error resolution requirements "for any prepaid account for which it has not successfully completed its consumer identification and verification process." Paragraph (e)(2)(i)(A) sets an alternate starting point for the 60-day window at "Sixty days after the date the consumer electronically accesses the consumer's account," provided that the electronic account transaction history made available to the consumer reflects the alleged error. The provisions are in the Electronic Code of Federal Regulations, 12 CFR 1005.18 Requirements for Financial Institutions Offering Prepaid Accounts.

Paper checks and non-electronic items. Regulation E addresses electronic fund transfers. A forged paper check, or a dispute about when deposited funds must be made available, runs on other schedules.

Accounts held for business purposes. The rules turn on a consumer asset account established primarily for personal, family or household purposes, so a business account generally sits outside the part.

Late notice. Where the 60-day window has passed, 1005.11 does not compel these procedures, though 1005.6(b)(4) directs the institution to extend those notice times to a reasonable period where the delay was due to extenuating circumstances and an institution may investigate under its own policy — a choice rather than a schedule the regulation sets.

What the section supplies, within its scope, is a set of counts that can be checked against a calendar. Two move with the institution's open days and two do not. Knowing which is which is the difference between a date that holds and a date that quietly slips a week.
