Does cash back cost money? Usually not. Pulling cash from your checking account at a store register is free at most major retailers, and the rewards you earn on a credit card don’t carry a direct charge. The costs show up in narrower situations: some stores add a fee to debit cash back, carrying a credit card balance can turn rewards into a loss, and taking cash off a credit card is expensive from the moment you do it.
Debit Cash Back at the Register
When you ask a cashier for cash back on a debit purchase, the amount is added to your transaction total and pulled straight from your checking account. A Consumer Financial Protection Bureau review found that Walmart, Target, CVS, Walgreens, and Albertsons all offer this without a fee.1Consumer Financial Protection Bureau. Issue Spotlight: Cash-Back Fees
Not every retailer does. The same review found Dollar General, Dollar Tree, Family Dollar, and Kroger all charge for debit cash back. Dollar store chains charge $1 to $2.50 depending on how much you request. Kroger brands charge $0.50 to $3.50, with larger withdrawals costing more.1Consumer Financial Protection Bureau.

Overdraft Risk on Debit Cash Back
If your balance doesn’t cover both the purchase and the cash back amount, the transaction can push your account negative. Federal rules say your bank cannot charge an overdraft fee on a one-time debit card transaction unless you specifically opted in to overdraft coverage.2Consumer Financial Protection Bureau. Regulation E – 1005.17 Requirements for Overdraft Services If you never opted in, the register will decline the transaction and you walk away with no fee and no cash.
If you did opt in, an overdraft fee can easily be larger than the cash back you asked for. Check your available balance before requesting cash back, and remember that pending transactions may make it lower than your account summary suggests.
How Credit Card Cash Back Rewards Work
Credit card cash back programs return a percentage of what you spend, usually 1 to 2 percent on general purchases and up to 5 or 6 percent in specific categories like groceries or gas. You can redeem the rewards as a statement credit, a deposit to your bank account, or a check.
These rewards aren’t paid by you. Card issuers fund them largely through the processing fees merchants pay to accept credit cards, so participating in a rewards program has no direct cost to the cardholder.
When Interest Erases Your Rewards
Rewards only save you money if you pay the statement balance in full each cycle. Carry a balance and the interest will almost certainly outrun anything you earned back.
As of late 2025, the average credit card interest rate was about 21 percent across all accounts, and about 22.3 percent among accounts actually paying interest.3Federal Reserve Board. Consumer Credit – G.19 – Current Release On $1,000 in spending, a 2 percent card earns you $20 in rewards. One month of interest on an unpaid $1,000 balance at those rates runs roughly $17 to $19, and the balance keeps compounding every month you don’t clear it.
Card issuers must disclose all interest rates, fees, and grace period terms in a standardized table before you open the account.4Office of the Law Revision Counsel. 15 USC 1637 – Open End Consumer Credit Plans Comparing purchase APRs there is the quickest way to see what carrying a balance would actually cost.
Cash Advances Always Cost Money
Taking physical cash off a credit card is a cash advance, and it’s the one form of cash back that always costs you. Three charges stack on top of each other:
- An upfront fee, usually 3 to 5 percent of the withdrawal or a $5 to $10 minimum, whichever is greater. A $500 advance at 5 percent costs $25 before any interest.
- No grace period. Interest starts the day you take the money.5Consumer Financial Protection Bureau. What Is a Grace Period for a Credit Card?
- A separate, higher APR than the one on purchases. Both rates appear in your card agreement.4Office of the Law Revision Counsel. 15 USC 1637 – Open End Consumer Credit Plans
Issuers must disclose the cash advance fee and APR before you open the account.6Consumer Financial Protection Bureau. Regulation Z – 1026.60 Credit and Charge Card Applications and Solicitations Pulling the same cash from your own checking account, whether at an ATM, a store register, or a teller window, avoids all three charges.
Is Cash Back Taxable?
Cash back you earn from credit card purchases is generally not taxable. The IRS treats spending-based rewards as a reduction of the purchase price rather than income.7Internal Revenue Service. Private Letter Ruling PLR-141607-09 Earn $200 in cash back over the year and the IRS views it as having paid $200 less for what you bought.
Rewards not tied to spending are treated differently. A sign-up bonus given simply for opening an account, with no purchase required, may be taxable income. If the taxable amount reaches $600 or more in a year, the card issuer may send a Form 1099-MISC.
Merchant Surcharges When Paying by Credit Card
Some merchants add a surcharge when you pay with a credit card, passing part of their processing cost to you. This is separate from any debit cash back fee and applies to the card payment itself. Where surcharges are allowed, card network rules generally cap them at around 3 percent, and the amount must appear as a separate line item on your receipt.
A few states prohibit credit card surcharges outright. In states that allow them, the merchant must notify you before you complete the transaction, usually through signage at the entrance or register. Surcharges cannot be applied to debit or prepaid card transactions, even when those cards run through a credit card network. Paying with debit, cash, or check avoids the charge.
