What a deposit slip is and why you need one

A deposit slip is a paper form you fill out when you put cash or checks into your bank account. It tells the bank how much money you're depositing, what form it's in (cash, checks, or both), and which account it should go into. You write the slip, hand it to the teller along with your money, and keep a copy for your records.

Deposit slips matter because they create a paper trail. If a check gets lost or a deposit doesn't show up in your account, the slip proves you made the deposit and when. They're also required by most banks when you deposit checks — the bank needs to know the check amounts and account number before processing them.

If your employer uses direct deposit, you won't need deposit slips for your paychecks. But you'll still use them for other deposits: tax refunds, personal checks from friends or family, cash you want to put in savings, or checks from side work.

Key Takeaways

  • A deposit slip is a form you complete at the bank that shows the amount, type, and destination of money you're depositing.
  • You fill in the date, account number, and itemize each check or cash amount on separate lines before handing it to the teller.
  • Keep your copy of the deposit slip as proof the deposit was made, especially if money doesn't appear in your account within one or two business days.
  • Most banks provide blank deposit slips at the teller window or in the lobby, and many let you order personalized slips with your account number pre-printed.
  • If you deposit checks regularly, ask your bank whether mobile deposit or ATM deposit is available — both skip the slip entirely.

How to fill out a deposit slip step by step

Start with the date at the top. Write today's date in the format your bank uses — usually MM/DD/YYYY. Next, write your account number. If you have personalized deposit slips, this is already printed; if you're using a blank slip from the bank, copy the number from your debit card or account statement.

Below that, you'll see columns for listing deposits. The left column is for checks; the right is for cash. For each check, write the check number and the amount on a separate line. Add up all the checks and write the total in the "checks" box. For cash, write the total in the "cash" box. Then add checks and cash together for the grand total at the bottom.

Some slips ask you to break cash into bills and coins — twenties, tens, fives, ones, and change. If yours does, write each amount on its own line. If the slip doesn't have those lines, just write the total cash amount. Sign the slip if your bank requires it (many do). Tear off your copy and keep it; hand the original and your money to the teller.

What happens after you hand in your deposit slip

The teller will verify the amounts you wrote match what you actually handed over. They'll stamp your copy with the date and time received, and sometimes the teller's initials. Money usually appears in your account within one business day for cash and checks from the same bank, and one to three business days for checks from other banks.

If you deposited a check and it doesn't show up after three business days, contact your bank with your deposit slip copy. The slip proves you made the deposit; the bank can trace what happened to the check from there. If the check was lost or damaged, the bank will ask the check writer to issue a replacement.

Personalized deposit slips and when to order them

Most banks let you order deposit slips with your account number pre-printed on them. This saves time filling out the slip and reduces the chance of writing your account number wrong. You can usually order them through your bank's website, by phone, or at a branch. Some banks print them free; others charge a small fee.

Personalized slips are worth ordering if you deposit checks regularly — more than once or twice a month. If you rarely deposit anything, the blank slips at the teller window work fine. Ask your bank how long personalized slips take to arrive; it's usually one to two weeks.

Alternatives to paper deposit slips

Many banks now let you skip the slip entirely. Mobile deposit lets you photograph the front and back of a check with your phone and submit it through the bank's app. ATM deposit lets you insert checks and cash directly into an ATM, which scans them and credits your account. Both methods are faster than waiting for a teller and don't require a slip.

Ask your bank which methods they offer. Mobile deposit usually works for checks up to a certain amount (often $5,000 to $10,000 per deposit). ATM deposit may have limits too. Cash can usually only go through ATM deposit if your bank's ATMs accept it — not all do. If you use either method, take a screenshot or photo of the confirmation screen as your proof of deposit.

Common mistakes to avoid

The most common error is writing your account number wrong. Double-check it against your debit card or statement before handing the slip to the teller. Another mistake is forgetting to add up the checks and cash correctly — the teller will catch this, but it slows things down. If you're depositing multiple checks, make sure you write each one on a separate line; writing "checks" without itemizing them makes it harder for the bank to process.

Don't assume the teller will catch math errors. If you write $500 when the check says $50, the teller may deposit $500 and you'll have to contact the bank to fix it. Always verify your slip matches the actual money and checks you're handing over before you leave the window.

Keeping records of your deposits

Your copy of the deposit slip is your proof. Keep it in a folder or envelope with other banking documents for at least a few months. If a deposit doesn't show up or there's a dispute about when money arrived, you'll have the stamped slip showing the date and time you made the deposit.

If you use mobile or ATM deposit, save the confirmation screen or email. Most banks also let you view deposit history in your online account — check there too. Having multiple records (the slip, the confirmation, and your account history) protects you if something goes wrong.

Frequently Asked Questions

What if I don't have a deposit slip?

Ask the teller for a blank one. Banks keep stacks of them at the teller window and in the lobby. You can also request personalized slips by mail or order them online. In a pinch, you can write the information on a piece of paper, but the bank prefers the official form.

Can I deposit checks without a slip?

Yes, if your bank offers mobile deposit or ATM deposit. You photograph or insert the check, and the system handles it without a paper slip. Some banks also let you hand a check to a teller without a slip, though they may ask you to fill one out anyway.

What if the teller says the amount doesn't match?

Stop and recount the money together. If you wrote $300 but only handed over $250, the teller will ask you to correct the slip. If the money is correct but you wrote it wrong, fix the slip before the teller processes it. Once it's processed, fixing errors takes longer.

How long do I need to keep my deposit slip copy?

Keep it for at least three months, or longer if the deposit included a large check. If a problem comes up, you'll have proof of when and how much you deposited. After three months, you can throw it away unless you need it for tax or record-keeping purposes.

Do I need a deposit slip if I'm depositing cash only?

Most banks require one, even for cash-only deposits. The slip documents how much cash you're putting in and creates a record for both you and the bank. Some banks may waive this for very small amounts, but it's safer to use a slip every time.
