Mobile check deposit limits and hold times at online banks

Limits, cutoffs and availability side by side

Figures below come from each bank's help pages and legal disclosures read on 30 October 2026. Where a bank does not publish a number, we say so instead of estimating one.

Regulation CC in plain English

Regulation CC is the Federal Reserve rule that sets how fast banks must make deposited funds available. The Federal Reserve summarizes the core: cash deposits, wire transfers and certain checks such as Treasury and cashier's checks generally must be available by the business day after deposit, with exception categories for new accounts, large deposits, repeatedly overdrawn accounts and emergencies, and the bank generally must notify you when it invokes an exception. [7] The CFPB's consumer explainer adds that cutoffs can be no earlier than 2:00 p.m. at physical locations and noon at an ATM or elsewhere, and that accounts open less than 30 days can face longer holds. [6]

Watch the dollar thresholds. The CFPB page we read still quotes 225 dollars for next-day availability and 5,525 dollars for large checks [6], while Capital One's current disclosure uses 275 dollars and 6,725 dollars [4] and Ally's October 2026 agreement uses 6,725 dollars for new-account mailed checks. [2] Rely on your bank's current disclosure and the hold notice it sends.

The bigger point for app users: both banks say mobile deposits sit outside those federal requirements. Capital One's disclosure states that checks deposited with its Mobile Deposit application are not subject to the funds availability requirements, and Ally's agreement says eligible eCheck deposits are not subject to Regulation CC availability requirements, although both say they generally follow their standard timeframes. [2][4] The CFPB likewise notes that banks may use a different timetable for mobile deposits and suggests asking about the policy. [6]

Worked example: depositing a 4,500 dollar check

A synthetic customer receives a 4,500 dollar personal check drawn on another bank and photographs it on a Tuesday afternoon, before both banks' cutoffs.

At Capital One, as an established customer, the funds are generally available Wednesday, the first business day after the deposit date. [3][4] The check is below the 6,725 dollar total that can trigger a four-business-day delay [4], but the bank can still apply an extended hold and would tell her when funds are available. [3] If her checking account were under 30 days old, the new-customer table points to the fourth business day for other check deposits. [4]

At Ally, as an established customer, the help page says funds are generally available by the second business day, so Thursday. [1] Ally's agreement describes the standard policy it generally follows for other checks: up to 300 dollars on the first business day and the rest on the second. [2] The 4,500 dollar check is well below the 25,000 dollar large-check trigger and inside the 50,000 dollar daily limit. [1] In the first 30 days of her first Ally account, the agreement says it would be available no later than the fifth business day. [2]

When to deposit some other way

If a check is above your Capital One app limit, Capital One says to use a branch or ATM [3]; its disclosure lists a total daily ATM check deposit limit of 999,999.99 dollars. [4] Ally has no branches, but mailed checks have no dollar limit [1], and for very large sums an incoming wire is available the same business day at both banks. [2][4]

Timing matters as much as the channel. At Ally, a deposit after the 7 pm ET cutoff or on a non-business day is processed on the next business day [1][2], so a Friday-night photo of a check starts its clock on Monday. Capital One says deposits made after its cutoff appear in your transaction history in two business days. [3] If you need the money for a specific bill, deposit early in the week and wait for the funds to show as available before paying.

Checklist for a smooth mobile deposit

• Endorse exactly as your bank asks: for Capital One mobile deposit plus your signature [3], or For Mobile Deposit Only with every payee's signature at Ally. [1]
• Check the date: Capital One rejects checks more than six months old or postdated; Ally needs a date within 180 days. [1][3]
• Do not try money orders, traveler's checks, foreign checks or checks payable to cash at Capital One. [3]
• Submit before the cutoff on a business day: 9 pm ET at Capital One, 7 pm ET at Ally. [1][3]
• Watch for a hold notice; Ally emails your deposit status within 1 business day. [1]
• Keep the paper check until the full amount posts, then shred it. [3]
• Mobile-depositing to a Capital One savings account? Expect a 4-business-day hold before withdrawal. [5]

Who this matters for

If checks are a small part of your money, the difference between next-day and second-day availability rarely matters. It matters if you get large checks (insurance settlements, contractor payments, property sales), if your account is new, or if you plan bills around deposit dates. In those cases Ally's published limits are easier to plan around, while Capital One's next-business-day norm and its branch and ATM network give a faster path for a single large check, if you live near one.
