Quick Answer
Alliant’s mobile deposit limit is one of the highest among U.S. credit unions: up to $100,000 per day and $250,000 over any rolling 30-day period. ATM deposits are capped at $10,000 per day for members in good standing. Because Alliant is a fully digital credit union with no branches, mobile deposit and its 80,000+ ATM network are the primary ways to deposit — and Alliant reimburses out-of-network ATM fees up to $20 a month for checking members. Cash deposits over $10,000 trigger a routine federal reporting requirement.
Three things that are specific to Alliant and worth knowing before you run into a problem:
- The mobile limit is unusually high — the constraint is availability, not the cap. At $100,000 a day, most members will never hit Alliant’s mobile deposit ceiling. The thing to plan around isn’t the limit; it’s how fast the funds clear, since large deposits are released in stages (more below).
- There are no branches. Alliant is digital-only. You deposit by mobile app or at a deposit-taking ATM — and not every ATM in the network accepts deposits, so check the ATM locator first. For cash, a deposit-taking ATM is the route; there’s no teller line to walk into.
- A hold is not a rejection. If Alliant places a hold, the deposit went through — you just can’t access the funds yet. That’s different from exceeding your deposit limit, which stops the deposit from being submitted at all. The two problems have different fixes.
Alliant Mobile Deposit Limits
Alliant sets a clear, published mobile deposit limit rather than a personalized one — and it’s high enough that most members never approach it.
| Limit | Amount |
|---|---|
| Mobile deposit — daily | $100,000 |
| Mobile deposit — rolling 30 days | $250,000 |
| ATM deposit — daily (good standing) | $10,000 |
| ATM deposit — daily (ChexSystems record) | $0 |
Note: ATM deposit eligibility depends on account standing. Members in good standing without a ChexSystems record have a $10,000 daily ATM deposit limit; members with a ChexSystems record have a $0 ATM deposit limit and must use mobile deposit instead. To deposit a check larger than the mobile limit, you can mail it to Alliant.
How to Check Your Mobile Deposit Limit
- Open the Alliant Mobile Banking app and sign in.
- Select Deposit or Mobile Deposit.
- Choose the account you want to deposit into.
- Your deposit limit appears before you submit the check. If no figure shows, the app will alert you only when a deposit exceeds your allowed amount.
See our mobile check deposit guide for the full step-by-step and common rejection fixes.
How Fast Alliant Deposits Clear
Like several credit unions, Alliant states that funds deposited via mobile check deposit are not subject to Regulation CC’s funds availability requirements — Alliant’s own funds availability policy applies instead. That policy is tiered by amount:
| Deposit Amount | Available No Later Than |
|---|---|
| First $275 | Day of deposit |
| $275.01 to $6,725 | 2nd business day after deposit |
| Over $6,725 | 5th business day after deposit |
| New accounts (first 30 days) | 7th business day |
So while the deposit limit itself is generous, a large check is released in stages rather than all at once. New-member deposits are held longer — during your first 30 days, checks are generally available on the seventh business day, a fraud-protection measure. (“Day of deposit” means the business day Alliant processes your deposit; exceptions can apply.)
How to Deposit at Alliant Without a Branch
Alliant is a digital credit union — there are no branches to walk into. That makes the question for most members “how do I deposit?” rather than “what’s my limit?” Your options:
- Mobile deposit: The primary method for checks, up to the $100,000 daily / $250,000 rolling limit.
- Deposit-taking ATMs: Alliant’s network spans 80,000+ surcharge-free ATMs — including Alliant-owned machines and the CO-OP, Allpoint, and partner networks — but not every ATM accepts deposits. Use the ATM locator in the app or on Alliant’s site to find one that does before you go.
- Mail-in deposit: For checks above the mobile limit, you can mail the check to Alliant.
- External transfer or direct deposit: Move money in from another bank, or route payroll directly to Alliant (routing number 271081528).
Alliant checking members are reimbursed for out-of-network ATM fees up to $20 per month, which softens the no-branch model considerably.
Why Your Alliant Mobile Deposit May Be Placed on Hold
Even when a deposit is within your limit, Alliant may hold the funds while it verifies the check. Common triggers:
- A check that’s large relative to your usual deposits
- A new or unfamiliar payer
- A recently opened account (first 30 days)
- A low-quality or incomplete check image
- A history of overdrafts or returned items
- A deposit made late in the day or on a weekend
Holds are standard fraud-prevention and verification procedure, and your available balance may differ from your current balance while funds process. See how bank holds work, or why Alliant transfers stay pending.
The $10,000 Deposit Rule
Depositing more than $10,000 is legal and routine. For cash transactions over $10,000, Alliant is required by the Bank Secrecy Act to file a Currency Transaction Report with FinCEN — automatic, and requiring nothing from you if the funds are legitimate. Deliberately splitting a large cash deposit into smaller amounts to stay under the threshold is structuring, a federal crime regardless of the source. Note that Alliant’s $10,000 figure for ATM deposits is a separate, day-to-day transaction limit, not the federal reporting threshold. Learn more in what happens when you deposit over $10,000.
Holds vs. Deposit Limits — The Difference
- A deposit limit stops you from submitting a deposit at all — the app declines it before processing. Solution: use an ATM, mail the check, or split it across days.
- A hold means the deposit was accepted but the funds aren’t available yet. The deposit is in your history; you just can’t withdraw the money. Solution: wait for the applicable availability date, or contact Alliant.
If you see a deposit in your transaction history that isn’t spendable, that’s a hold — not a rejection. If you tried to submit a deposit and got an error, that’s a limit issue.
How to Increase or Work Around Your Alliant Deposit Limit
Because the mobile limit is already $100,000/day, most members won’t need an increase. If you’re hitting limits or holds, the practical levers are:
- Keep your account in good standing and use direct deposit regularly
- Maintain steady balances and a consistent deposit history
- Avoid overdrafts and returned items
- For a check above the mobile limit, mail it to Alliant or use a deposit-taking ATM (up to $10,000)
- Contact Alliant member support at 800-328-1935 to request a review

Frequently Asked Questions
What is the Alliant mobile deposit limit?
Alliant’s mobile deposit limit is up to $100,000 per day and up to $250,000 over any rolling 30-day period — one of the highest among U.S. credit unions. ATM deposits are limited to $10,000 per day for members in good standing.
How long does an Alliant mobile deposit take to clear?
Alliant makes a minimum of $275 available the day of deposit. Amounts from $275.01 to $6,725 are generally available by the second business day, and amounts over $6,725 by the fifth business day. During your first 30 days as a member, checks are generally held until the seventh business day. Alliant mobile deposits are not governed by Regulation CC; Alliant’s own funds availability policy applies.
Does Alliant have branches for deposits?
No. Alliant is a digital credit union with no branches. You deposit by mobile app, at a deposit-taking ATM (not every ATM in the 80,000+ network accepts deposits — check the locator), by mail, or by transferring funds in from another institution. Checking members are reimbursed for out-of-network ATM fees up to $20 a month.
What is the Alliant ATM deposit limit?
$10,000 per day for members in good standing without a ChexSystems record. Members with a ChexSystems record have a $0 ATM deposit limit and must use mobile deposit. Not all ATMs accept deposits, so confirm with the ATM locator first.
Can I deposit a check larger than $100,000 with Alliant?
The mobile deposit limit is $100,000 per day. For a larger check, you can mail it to Alliant for deposit. Funds availability still follows Alliant’s tiered policy, so a large check will be released in stages rather than all at once.
Why did Alliant put a hold on my deposit?
Holds are common for large checks, unfamiliar payers, new accounts, low-quality images, or a history of returned items. A hold means the deposit was accepted — the money is in your account — but funds aren’t available yet. Alliant makes at least $275 available the day of deposit and releases the rest on the schedule above.
What’s the difference between a deposit limit and a hold?
A deposit limit stops you from submitting a deposit — the app declines it before processing. A hold means the deposit was accepted but funds aren’t available yet. If a deposit appears in your transaction history, it went through — that’s a hold, not a rejection.
Bottom Line
Alliant’s mobile deposit limit is high — $100,000 per day and $250,000 over a rolling 30-day period — so for most members the limit is never the issue. What matters more is how a large check clears: Alliant makes at least $275 available the day of deposit and releases the rest in stages, up to the fifth business day for larger amounts, with longer holds for new accounts. As a branchless credit union, Alliant relies on mobile deposit and an 80,000+ ATM network (with up to $20/month in fee rebates), and ATM deposits are capped at $10,000 a day.
If a deposit shows up but isn’t spendable, that’s a hold — not a failure. Check your limit and availability in the Alliant app, or call 800-328-1935 for help.
