Most banks do not cap how much cash you can hand over at the teller window, but depositing more than $10,000 triggers automatic federal reporting rules that every bank must follow, regardless of where the money came from or why you are depositing it.
At a Glance
- Banks generally have no cash deposit ceiling, though ATMs often limit the number of bills accepted per transaction.
- Any deposit over $10,000 requires the bank to file a Currency Transaction Report with the federal government.
- FDIC insurance only covers up to $250,000 per depositor, per bank, so very large sums may need to be split across institutions.
- Breaking up deposits to dodge reporting, known as structuring, is a federal crime even when the money is entirely legitimate.
- In person deposits are the safest route for large cash sums, and armored transport becomes worth considering above roughly $50,000.
How Much Cash Can You Actually Deposit at Once
There is no blanket rule stopping someone from walking into a bank with $30,000 in cash and depositing all of it in a single transaction. The friction usually shows up at the machine, not the teller counter. ATMs are often built to accept only a set number of bills per deposit, say 40, which caps how much you can feed in at once. If those are $100 bills, that works out to a $4,000 ceiling per transaction. Need to deposit more? You may simply have to run a second transaction, assuming the machine or your account allows it.
Some banks and fintech platforms set their own limits, and they vary quite a bit. Capital One allows one time deposits up to $5,000, though it does not cap ATM deposits on a daily basis. Chime, a banking app that partners with retail locations, limits cash deposits to $1,000 per day when using Walgreens registers. Credit unions tend to be more generous: Alliant Credit Union permits up to $100,000 a day through mobile deposit and $10,000 a day at ATMs, while Navy Federal Credit Union caps ATM deposits at $10,000 per card per day through a CO OP network machine.
| Institution | Cash Deposit Limit |
|---|---|
| Capital One | $5,000 per one time deposit; no daily ATM limit |
| Chime | Up to $1,000 per day at Walgreens registers |
| Alliant Credit Union | $100,000 per day via mobile deposit; $10,000 per day at ATMs |
| Navy Federal Credit Union | $10,000 per card per day at a CO OP ATM |
Because these figures shift and vary by account type, call your bank before you show up with a large sum. A quick phone call can save you a wasted trip or an awkward conversation at the counter.
Why the $10,000 Threshold Exists
Federal law requires banks to report any cash deposit over $10,000, no exceptions, no matter the source of the funds. The bank does this by filing a Currency Transaction Report, or CTR, with the Financial Crimes Enforcement Network, an arm of the Treasury Department known as FinCEN. This obligation traces back to the Bank Secrecy Act and was reinforced by the USA PATRIOT Act, both aimed at giving the government a paper trail to spot money laundering or funding tied to criminal or terrorist activity.
The rule is not limited to one big deposit. If you make several smaller cash deposits in a single day that together exceed $10,000, the bank still has to file a CTR. Banks are also required to keep deposit records, generally for at least five years, though many hold onto them longer.
The Safest Way to Move a Large Amount of Cash
Visiting a branch in person remains the most secure way to deposit a substantial sum. A banker can count the cash with you in a private area, which limits disputes over the amount and cuts down on the risk of carrying cash around longer than necessary. Alex King, a former vice president in Trade and Working Capital at Barclays Bank and founder of the site Generation Money, suggests carrying the cash in a briefcase or an opaque, secure bag rather than anything that draws attention to what you are holding.
King also recommends bringing a valid form of identification along with paperwork that documents where the cash came from, things like business invoices or legal records. That documentation matters more than people think, since it can head off questions later if the bank or regulators ever ask about the source of the funds.
For deposits north of $50,000, King says armored transport starts to make practical sense, particularly for business owners handling recurring cash volume.
