Under federal law, Saturdays are not business days for banks, even when a branch is open and tellers are working the counter. 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 Saturday usually sits in a holding pattern until Monday.
Business Day Versus Banking Day
The Federal Reserve implements the Expedited Funds Availability Act through 12 CFR Part 229, known as Regulation CC. A “business day” is any calendar day except Saturdays, Sundays, and ten named federal holidays, and 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 separate term, “banking day,” means the portion of a business day during which a bank is open to carry out substantially all of its functions.2eCFR. 12 CFR Part 229 – Availability of Funds and Collection of Checks (Regulation CC) Because a banking day must fall within a business day, and Saturday is never a business day, Saturday can never be a banking day. The hours a branch keeps on Saturday have no bearing on this. Every federal timeline for deposit availability, check clearing, and fund holds runs on the Monday-to-Friday calendar.
When a Saturday Deposit Becomes Available
A deposit made on Saturday is treated as received on the next banking day, which is normally Monday.3eCFR. 12 CFR 229.19 – Miscellaneous From that Monday, the availability clock runs differently depending on what you deposited and how.
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. The banking day is Monday, so the deadline is Tuesday. Cash deposited through an ATM or any method that does not involve a bank employee gets a longer window — the second business day after the banking day, which pushes availability to Wednesday for a Saturday deposit.4eCFR. 12 CFR 229.10 – Next-Day Availability
Checks
Most personal and business checks must be made 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. A few check types get next-day treatment when deposited in person to a bank employee: U.S. Treasury checks, postal money orders, cashier’s checks, and government checks. Deposited that way on Saturday, they should be available Tuesday.4eCFR. 12 CFR 229.10 – Next-Day Availability
The $275 Floor and the $6,725 Ceiling
As of July 2025, Regulation CC requires at least the first $275 of any check deposit to be available by the next business day, even on deposits otherwise subject to a longer hold. For a Saturday check deposit, $275 should be accessible by Tuesday. Deposits larger than $6,725 can trigger the large-deposit exception, which allows the bank to extend the hold several additional business days.6Federal Reserve Banks.

Monday Holidays Make It Worse
Several federal holidays — Martin Luther King Jr. Day, Presidents’ Day, Memorial Day, Labor Day, and Columbus Day — always fall on a Monday.2eCFR. 12 CFR Part 229 – Availability of Funds and Collection of Checks (Regulation CC) On those weekends, Monday is neither a business day nor a banking day, so a Saturday deposit rolls to Tuesday as its banking day of deposit.
A regular check deposited Saturday before a Monday holiday would not need to be released until Thursday. Cash handed to a teller that same Saturday would not need to clear until Wednesday. Depositing right before a holiday weekend can cost you an extra day or more of waiting, so time any deposit meant to cover an early-week payment accordingly.
ATM Deposits on Saturday
Cutoff times — generally no earlier than 2:00 p.m. for in-person deposits and noon for ATM deposits — are largely moot on Saturday.3eCFR. 12 CFR 229.19 – Miscellaneous Because Saturday is not a banking day, a deposit at 9:00 a.m. and a deposit at 9:00 p.m. are both treated as received Monday.
The ATM you use matters more than the time. Deposits at a “nonproprietary” ATM — one not operated by your own bank — follow a much longer schedule: the bank has until the fifth business day after the banking day of deposit to release funds.2eCFR. 12 CFR Part 229 – Availability of Funds and Collection of Checks (Regulation CC) A check dropped at a nonproprietary ATM on Saturday becomes a Monday deposit, with funds potentially unavailable until the following Monday. That is a full week. Using your bank’s own ATM, or depositing in person, avoids the extended delay.
ACH and Wire Transfers Pause on Saturday
ACH transfers and Fedwire transactions both run on Federal Reserve infrastructure, and neither system settles on weekends.7Federal Reserve Board. Automated Clearinghouse Services An ACH payment you initiate on Saturday — a direct deposit, bill payment, or person-to-person transfer — sits in queue until the processing window opens Monday. The same applies to wires: even if your bank’s website accepts the request on Saturday, the money does not move between institutions until the next business day.
Same Day ACH, which can settle individual transactions up to $1 million within hours, is only available on business days.8Nacha. Increasing the Same Day ACH Dollar Limit A Same Day ACH initiated Saturday will settle Monday at the earliest.
Instant Payments That Do Work on Saturday
Two newer systems can move money on weekends. The Federal Reserve’s FedNow Service operates on a 24-hour funds-transfer business day every day of the week, including Saturdays, Sundays, and Federal Reserve holidays.9Federal Reserve Services. FedNow Service Operating Hours Settlement is immediate and final, with a per-transaction limit of $10 million as of 2026.10Federal Reserve Services. Announcing 2026 Federal Reserve Financial Services Fees
The Real-Time Payments (RTP) network, run by The Clearing House, processes transactions around the clock, 365 days a year, with instant settlement and individual payments up to $10 million.11The Clearing House. Real Time Payments
Your bank has to participate for you to use either one. As of early 2026, roughly 1,650 financial institutions have joined FedNow, and RTP participation, while growing, is not universal. A real-time weekend payment also depends on the recipient’s bank being on the same network. Confirm with your bank whether FedNow or RTP is available through your account before counting on a Saturday transfer.
Bills Due on a Saturday
When a bill’s due date is a Saturday, the answer depends on the type of debt. Credit card issuers that do not receive or accept mailed payments on the due date generally cannot treat a mailed payment received the next business day as late. If your card payment is due Saturday and the mailed check arrives Monday, the issuer should not charge a late fee. This protection does not automatically extend to electronic or phone payments: if the issuer accepts online payments on Saturday, it can enforce the Saturday deadline for those.12Consumer Financial Protection Bureau. Regulation Z – 1026.10 Payments
Mortgage payments, utility bills, and other obligations follow your contract and applicable state law. Many mortgage servicers offer a grace period, often 15 days, that absorbs a weekend due date, but that grace period is set by your loan agreement, not by federal rule. If you are relying on ACH or a bank transfer to cover a weekend deadline, remember the transfer will not settle until Monday. Scheduling the payment for Friday or earlier is the safer move.
Overdraft Risk Over the Weekend
Because Saturday deposits are not credited until Monday, debit transactions that hit your account over the weekend — recurring bill payments, subscription charges, debit card purchases — may be processed against your Friday closing balance rather than any Saturday deposit. Banks have discretion in how they order transactions for Monday morning posting, 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)
There is one narrow protection. 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 overdraft fees caused solely by that delay, provided the check ultimately clears.2eCFR. 12 CFR Part 229 – Availability of Funds and Collection of Checks (Regulation CC) Outside that scenario, assume a Saturday deposit will not shield you from overdraft charges on weekend transactions, and keep a cushion for anything that may post before Monday.
