Most ATMs accept large checks, but your bank may hold the funds longer

Yes, you can deposit a large check at an ATM if your bank's machine accepts check deposits. The size of the check itself is not the barrier — ATMs process checks of $10,000, $50,000, or more the same way they process smaller ones. The real limits are the daily deposit cap your bank sets on ATM transactions and the hold period the bank places on the funds after deposit.

A $5,000 check and a $50,000 check both go into the same envelope slot. What changes is how long your bank takes to clear it and make the money available to you. Large checks trigger longer holds because banks are more cautious about fraud on high-value deposits.

Key Takeaways

  • ATM daily deposit limits typically range from $5,000 to $25,000 per transaction, depending on your bank and account type, so a check larger than that limit cannot go through the machine.
  • Checks deposited at an ATM usually face a longer hold than checks deposited in person at a branch, often 5 to 10 business days for large amounts.
  • If your check exceeds your ATM's daily limit, you must deposit it in person at a branch or through mobile check deposit if your bank offers it.
  • Banks are required to disclose their hold policies in writing, so you can find the exact hold period for large deposits in your account agreement or by calling customer service.

ATM deposit limits and how they work

Each bank sets its own daily limit on how much you can deposit through an ATM in a single day. Common limits are $5,000, $10,000, or $25,000 per transaction, though some banks allow higher amounts for certain account types. If your check is larger than your bank's ATM limit, the machine will reject it — you cannot split a single check across multiple deposits.

To find your specific limit, check your account agreement, log into your online banking portal, or call your bank's customer service line. The limit may be different for ATM deposits than for mobile deposits or branch deposits, so ask specifically about ATM machines. Some banks also raise limits for customers with longer account histories or higher balances, so if you have been with the bank for years, your limit may be higher than a new customer's.

Hold periods for large checks at ATMs

When you deposit a check at an ATM, your bank must disclose how long it will hold the funds before making them available. For checks under $5,000, many banks clear them within one business day. For larger checks, holds are typically longer — often 5 to 10 business days — because the bank wants to confirm the check will not bounce before releasing the money to you.

The hold period starts the day the bank receives the deposit, not the day you made it. If you deposit a check at an ATM on Friday evening, the bank may not process it until Monday, so the hold clock starts Monday. During the hold period, the money shows in your account balance but is not available to withdraw or spend. After the hold lifts, the funds become available.

When to deposit in person instead of at an ATM

If your check is larger than your ATM's daily limit, you must go to a branch and deposit it in person with a teller. Tellers can process checks of any size and can often clear them faster than ATM deposits. A teller can also answer questions about holds on the spot and may be able to reduce the hold period if you have a long history with the bank.

Depositing in person is also worth considering if you need the money quickly. A teller may place a shorter hold on a large check than an ATM would, especially if you have a good account history. Some banks offer next-business-day availability for large checks deposited before a certain time at a branch, though this is not may provide.

Mobile check deposit as an alternative

Many banks now offer mobile check deposit through their smartphone app, which lets you photograph the front and back of a check and submit it without visiting an ATM or branch. Mobile deposit often has its own daily limit — sometimes higher than ATM limits, sometimes lower — so check your bank's app to see what yours is.

Mobile deposits typically face the same hold periods as ATM deposits, sometimes longer. The advantage is convenience: you can deposit from home or work without finding an ATM. The disadvantage is that if your check exceeds the mobile limit, you still have to go to a branch.

What happens if a large check bounces

If you deposit a large check and it bounces after the hold period ends, your bank will reverse the deposit and charge you a returned-check fee, usually $10 to $30. You are responsible for any overdraft fees if the reversal puts your account negative. This is why banks hold large checks longer — they want time to confirm the check is good before releasing the money.

If you suspect a check might bounce, ask the person or business who gave it to you to confirm the account has sufficient funds. If you are depositing a very large check from someone you do not know well, consider asking them to wire the money instead or to provide a cashier's check, which is may provide by the bank.

How to speed up a large check deposit

If you need the money from a large check quickly, deposit it in person at a branch rather than at an ATM. Explain to the teller that you need the funds as soon as possible. Some banks will reduce the hold period for customers with good account standing, though they are not required to.

Another option is to ask the person or business who issued the check to wire the funds instead. A wire transfer clears within one business day and does not require a hold. If that is not possible, a cashier's check (which the issuer can obtain from their bank) is also faster to clear than a personal check.

Frequently Asked Questions

What is the largest check an ATM will accept?

ATMs do not have a size limit on the check itself — they will scan and accept a check for $100,000 if your bank's daily deposit limit allows it. The limit is on how much you can deposit in a single day, not on the value of any one check. If your check exceeds that daily limit, the machine rejects it.

Will a large check clear faster if I deposit it at a branch instead of an ATM?

Often yes. Deposits made in person at a branch may clear faster than ATM deposits because a teller can verify the check immediately and may place a shorter hold. However, the hold period depends on your bank's policy and the check amount, so call ahead to ask what hold period applies to your specific deposit.

Can I deposit a large check through my bank's mobile app?

Many banks offer mobile check deposit, but it usually has its own daily limit separate from ATM limits. Check your bank's app to see if mobile deposit is available and what the limit is. Holds on mobile deposits are typically the same as ATM holds, sometimes longer.

What should I do if my bank's ATM rejects my large check?

Visit a branch during business hours and deposit it in person with a teller. Bring your account number or debit card and a photo ID. The teller can process any check amount and can tell you immediately what hold period will apply.

Do I need to endorse a check before depositing it at an ATM?

Yes. Sign the back of the check and write "For deposit only" followed by your account number. This protects you if the check is lost before the bank processes it. Some ATMs also ask you to enter your account number on the screen before inserting the check.
