No, Saturdays are not business days for banks under federal law, even when a branch is open and staffed. The Expedited Funds Availability Act defines a “business day” as any day other than a Saturday, Sunday, or legal holiday, and that definition controls when deposits clear, when transfers settle, and when the clock starts on fund availability.1Office of the Law Revision Counsel. 12 USC 4001 – Definitions Money you deposit or send on a Saturday typically sits in a holding pattern until Monday.
What Federal Law Actually Says
The Federal Reserve implements the Expedited Funds Availability Act through 12 CFR Part 229, known as Regulation CC. Under those rules, a business day is any calendar day except Saturdays, Sundays, and ten named federal holidays. When one of those holidays falls on a Sunday, the following Monday is also excluded.2eCFR. 12 CFR Part 229 – Availability of Funds and Collection of Checks (Regulation CC)
A related term is “banking day,” which is the portion of a business day during which a bank is open to the public for carrying out substantially all of its banking functions.2eCFR. 12 CFR Part 229 – Availability of Funds and Collection of Checks (Regulation CC) Because a banking day has to fall within a business day, and Saturday is never a business day, Saturday can never be a banking day no matter how many hours the branch keeps its doors open. Every federal timeline tied to deposit availability, check clearing, and fund holds runs on this calendar.
When Saturday Deposits Actually Show Up
A deposit made on Saturday is treated as if received on the next banking day, usually Monday.3eCFR. 12 CFR 229.19 – Miscellaneous The availability clock does not start until then, and how quickly you can withdraw depends on what you deposited.
Cash
Cash handed to a teller on Saturday must be available for withdrawal no later than the business day after the banking day of deposit. Since the banking day is Monday, that means Tuesday. Cash deposited through an ATM or another method that does not involve a bank employee has a longer deadline: the second business day after the banking day of deposit, or Wednesday for a Saturday drop.4eCFR. 12 CFR 229.10 – Next-Day Availability
Checks
Most personal and business checks must be available by the second business day after the banking day of deposit.5eCFR. 12 CFR Part 229 – Availability of Funds and Collection of Checks (Regulation CC) – Section 229.12 Availability Schedule A check deposited Saturday is treated as deposited Monday, so funds should be available by Wednesday. Certain categories get faster treatment: U.S. Treasury checks, postal money orders, cashier’s checks, and government checks deposited in person to a bank employee qualify for availability by the first business day after the banking day of deposit, or Tuesday in this scenario.4eCFR. 12 CFR 229.10 – Next-Day Availability
The First $275
As of July 2025, Regulation CC requires banks to make at least the first $275 of any check deposit available by the next business day, even for checks that would otherwise sit on a longer hold. For a Saturday check deposit, at least $275 should be accessible by Tuesday. Deposits above $6,725 may be subject to extended holds under the large-deposit exception, which can push full availability out several additional business days.6Federal Reserve Banks.

When Monday Is a Federal Holiday
Five of the ten federal holidays that Regulation CC excludes from business-day status always fall on a Monday: Martin Luther King Jr. Day, Presidents’ Day, Memorial Day, Labor Day, and Columbus Day.2eCFR. 12 CFR Part 229 – Availability of Funds and Collection of Checks (Regulation CC) When a holiday lands on Monday, that day is neither a business day nor a banking day, so a Saturday deposit rolls to Tuesday as its banking day of deposit.
The downstream effect is meaningful. A regular check deposited on a Saturday before a Monday holiday would not need to be made available until Thursday, the second business day after Tuesday. A cash deposit handed to a teller that same Saturday would not be required to clear until Wednesday. Depositing before a holiday weekend can add an extra day or more of waiting.
ATM Deposits and Cutoff Times
On days a bank is open, the institution may set a cutoff no earlier than 2:00 p.m. for in-person deposits and no earlier than noon for ATM deposits, after which the deposit is treated as received on the next banking day.3eCFR. 12 CFR 229.19 – Miscellaneous On Saturday this rule barely matters, because a Saturday deposit rolls to Monday regardless of the hour you make it.
ATM deposits deserve special attention when you use a machine that does not belong to your bank. Deposits at these nonproprietary ATMs follow a much longer schedule: the bank has until the fifth business day after the banking day of deposit to release the funds.2eCFR. 12 CFR Part 229 – Availability of Funds and Collection of Checks (Regulation CC) A check deposited at a nonproprietary ATM on Saturday would be treated as deposited Monday, with funds potentially unavailable until the following Monday. A full week. Using your own bank’s ATM or depositing in person avoids that delay.
ACH and Wire Transfers Wait Until Monday
Automated Clearing House (ACH) transfers and Fedwire transactions run on Federal Reserve infrastructure, and neither system currently settles on weekends.7Federal Reserve Board. Automated Clearinghouse Services An ACH payment you initiate on Saturday, whether a direct deposit, a bill payment, or a person-to-person transfer, sits in a queue until the Federal Reserve’s processing window opens Monday morning. Wires work the same way: even if your bank’s website accepts a wire request on Saturday, the actual movement of money between institutions waits for the next business day.
Same Day ACH, which allows individual transactions up to $1 million to settle within hours, is only available on business days.8Nacha. Increasing the Same Day ACH Dollar Limit A Same Day ACH payment sent on Saturday will settle Monday at the earliest. The Federal Reserve has announced plans to expand Fedwire to a near-round-the-clock, six-day schedule, but that change is not expected until 2028 or 2029.9Federal Register.

What Does Move on a Saturday: FedNow and RTP
Two newer systems can move money instantly on Saturdays, Sundays, and holidays. The Federal Reserve’s FedNow Service operates on a 24-hour funds-transfer business day every day of the week, including weekends and Federal Reserve holidays.10Federal Reserve Services. FedNow Service Operating Hours Settlement is immediate and final, with a per-transaction limit of $10 million as of 2026.11Federal Reserve Services. Announcing 2026 Federal Reserve Financial Services Fees
The Real-Time Payments (RTP) network, operated by The Clearing House, likewise runs 365 days a year with instant settlement and no scheduled downtime. RTP handles individual payments up to $10 million.12The Clearing House. Real Time Payments
Your bank has to participate for you to use either. As of early 2026, roughly 1,650 financial institutions have joined FedNow, a fraction of the total number of U.S. banks and credit unions. RTP participation is growing but is not yet universal. Whether you can send or receive a real-time payment on a Saturday depends on whether both your bank and the recipient’s bank are on the same network. Ask your bank if either option is available on your account.
Bill Payments and Weekend Due Dates
When a bill’s due date falls on a Saturday, the rules depend on the type of debt. Credit card issuers that do not receive or accept mailed payments on the due date generally cannot treat a payment received the next business day as late. If your credit card payment is due Saturday and it arrives by mail on Monday, the issuer should not charge a late fee for the mailed payment. This protection does not automatically extend to electronic or phone payments — if the issuer accepts online payments on Saturday, it can hold you to that Saturday deadline for anything sent electronically.13Consumer Financial Protection Bureau. Regulation Z – 1026.10 Payments
Mortgage payments, utilities, and other obligations follow the terms of your contract or applicable state law. Many mortgage servicers offer a grace period, commonly 15 days, before assessing a late charge, which often absorbs a weekend due date. That grace period is set by your loan agreement, though, not by a blanket federal rule. If a deadline falls on a weekend and you are relying on ACH or a bank transfer to cover it, remember the transfer will not settle until Monday. Schedule Friday or earlier to be safe.
Overdraft Exposure Over the Weekend
Because Saturday deposits are not credited until Monday under Regulation CC, any debit transactions that hit your account over the weekend, including recurring bill payments, subscription charges, and debit card purchases, may be processed against your Friday closing balance rather than a balance that includes Saturday deposits. Banks have discretion in how they order transactions for posting Monday morning, and Regulation CC does not require them to apply Saturday deposits before processing weekend debits.2eCFR. 12 CFR Part 229 – Availability of Funds and Collection of Checks (Regulation CC)
One protection is worth knowing. If a bank places an extended hold on your deposit under Regulation CC’s “reasonable cause” exception and fails to give you written notice of the hold at the time of deposit, it cannot charge you overdraft fees that resulted solely from that delay, provided the deposited check ultimately clears.2eCFR. 12 CFR Part 229 – Availability of Funds and Collection of Checks (Regulation CC) Outside that narrow scenario, assume a Saturday deposit will not shield you from overdraft charges on weekend transactions, and keep enough in your account to cover any automatic payments that may post before Monday.
