If your checking account pays cash back, December is the month to log in and look at two numbers: the rewards balance you have not collected, and how much of the annual earning cap you have left. Most rewards checking accounts pay out automatically, but the caps, category rules and direct-deposit requirements mean a year of spending can end with far less than you assumed — or with money sitting in a rewards balance you could lose. A "cashback checking account" is a bank account that pays a percentage back on debit card purchases, the way a rewards credit card does. The three best-known versions — Discover, Upgrade and Chime — each limit the reward in a different way, so the year-end check is different for each one.

What a year-end check actually involves
Open your account and find the rewards or Cashback Bonus section, not just the balance. You are looking for four things, and each one has a different consequence: That takes ten minutes and it is the only way to know whether the account earned what you think it did.
A rewards balance that is paid out monthly needs no action. A balance that accumulates until you redeem it does.
- The unredeemed rewards balance, and whether redemption happens automatically or needs a click.
- How much of the monthly or annual cap you have used, since an unused cap expires with the calendar.
- Whether you met the direct-deposit requirement every month, which some accounts treat as the on/off switch for earning at all.
- Which purchase categories actually counted, because exclusions are usually broader than the marketing.
Discover's monthly ceiling and the closure trap
Discover's Cashback Debit account pays 1% back on up to $3,000 in debit card purchases a month. That is $30 a month and $360 a year at the absolute maximum, and according to Discover's Cashback Debit product page the account pays no interest on the checking balance itself. If you spend $5,000 on the card in a month, the last $2,000 earns nothing — so a December spending push on an already-maxed month is wasted. The balance itself is not on a deadline. Discover's National Deposit Account Agreement states that debit card Cashback Bonus does not expire, but that unredeemed Cashback Bonus may be forfeited if the account is closed for any reason.
The risk is not the calendar. It is closure — yours or the bank's. That makes one rule concrete: redeem before you close. Discover also offers automatic monthly redemption into an eligible Discover savings account, a feature the company announced in a 2018 press release, which removes the need to remember a year-end sweep at all. If you are still redeeming by hand, turning that on is the single best use of this year-end check.
Upgrade's cap resets January 1 — and may already be spent
Upgrade's Rewards Checking Preferred pays 2% back in selected categories, but the Upgrade help center caps that at $500 in rewards per calendar year — about $25,000 of eligible purchases — and the cap resets on January 1. December is therefore the month to check whether you have already hit it. If you have, the card earns nothing more until the new year and any large planned purchase belongs in January. The categories are narrow.
Upgrade limits the 2% rate to convenience stores, drugstores, restaurants and bars, gas stations, utilities, and monthly subscriptions, and its cash back categories page explicitly excludes groceries, travel, medical bills, online retailers, rent, mortgage, insurance and car payments. Those exclusions cover most households' biggest line items, which is why real-world earnings land nowhere near $500. There is a harder condition underneath all of it. Upgrade states that an account receiving under $1,000 in eligible direct deposits per month, more than 60 days after opening, earns no cash back at all. A year of category spending can return nothing if the paycheck stopped landing in that account — check your deposit history month by month, not just the current month.
Chime's higher rate carries a steeper requirement
Chime's structure inverts the trade-off: a much better rate, behind a much larger deposit hurdle. Under the Chime membership tiers terms, Prime members with a Chime Card earn 5% cash back on up to $1,500 of eligible monthly purchases, capped at $75 a month — and Prime status requires $3,000 in qualifying direct deposits within the preceding 34 days.
The 34-day window is the part worth noting at year-end. It is a rolling requirement, not an annual one, so a gap in December pay timing — a holiday payroll shift, a bonus routed to a different account, a month of reduced hours — can drop the tier and switch off the 5% for that period. Confirm which months you actually held the tier before you count the year's rewards.
Why unredeemed rewards are a real risk, not a theoretical one
This is not a niche worry. In a May 2024 issue spotlight on credit card rewards, the Consumer Financial Protection Bureau found that issuers "forfeit, expire, revoke, or otherwise take away hundreds of millions of dollars in earned rewards value each year," with consumers reporting cash back vanishing when an account closed. The bureau logged more than 1,200 rewards complaints in 2023, up over 70% from pre-pandemic levels.
The CFPB followed with a circular on December 18, 2024 warning that devaluing already-earned rewards, or revoking them under buried or vague conditions, may be an unfair, deceptive or abusive act. That is the regulatory backdrop, but it is not a refund mechanism. The practical takeaway is simpler: read your own account's rewards terms, and do not leave a large balance unredeemed while you are thinking about switching banks.
The tax line nobody expects
Cash back on your own purchases is generally treated as a purchase rebate rather than income. A bank bonus for opening or funding the account is different.
IRS Publication 550 says interest credited to your account that you can withdraw is taxable, and that gifts or incentives for opening or funding a deposit account may be reported to you as interest on Form 1099-INT. So if your year-end check turns up a $200 account-opening bonus alongside your cash back, expect it to show up as interest income — and remember that the obligation to report it does not depend on a form arriving in the mail. Set the paperwork aside now, while you are already logged in, rather than hunting for it in April.
Frequently Asked Questions
Does my debit cash back expire at the end of the year?
Not with Discover — its deposit account agreement says debit Cashback Bonus does not expire. What resets on January 1 is an earning cap like Upgrade's $500 annual limit, which is unused capacity, not money you already hold.
I am switching banks in January. What should I do first?
Redeem the rewards balance before you submit the closure request. Discover's agreement allows forfeiture of unredeemed debit Cashback Bonus when an account is closed for any reason.
Should I put December holiday spending on a rewards debit card?
Only after checking the cap and the categories. Discover stops paying past $3,000 of purchases in a month, and Upgrade's 2% excludes groceries, online retailers and travel — three of the biggest December categories.
