Yes, bank bonuses are taxable. The IRS treats the cash you receive for opening a checking, savings, or CD account as interest income, taxed at your ordinary income rate. The bank reports it on Form 1099-INT alongside any regular interest your deposits earned, and you owe federal income tax on every dollar whether or not a form shows up in the mail.1Internal Revenue Service. Publication 550 (2025), Investment Income and Expenses
Why the IRS Calls It Interest, Not a Gift
A gift, in tax terms, comes with no strings. A bank bonus always has strings: open the account, deposit a minimum, keep the money there for a set period, set up direct deposit. The bank is paying you for the use of your money, so the payment is interest under the tax code. IRS Publication 550 addresses cash received for opening bank accounts and making deposits directly, confirming it is reportable as interest.1Internal Revenue Service. Publication 550 (2025), Investment Income and Expenses
This is where bank bonuses part ways with credit card rewards. Cash back on card spending is generally not taxable because the IRS treats it as a rebate that reduces what you paid for your purchases.2Internal Revenue Service. PLR-141607-09 A bank bonus isn’t reducing the price of anything. You deposited cash and the bank paid you for it. That is income.
How the Bank Reports Your Bonus
When a bank pays you $10 or more in combined bonuses and interest during a calendar year, it must send you Form 1099-INT and file a copy with the IRS.3Internal Revenue Service. Instructions for Forms 1099-INT and 1099-OID (01/2024) The bonus appears in Box 1, “Interest Income,” usually bundled with the regular interest the account earned. Open accounts at three banks and expect three separate 1099-INTs.
The $10 threshold controls only whether the bank must send a form. It does not control whether you owe tax. A $5 bonus from a small promotion is still taxable interest, and you are responsible for reporting it even without a 1099-INT.4Internal Revenue Service. Topic No. 403, Interest Received
Backup Withholding
If the bank never got a valid Social Security or taxpayer ID number from you, or the IRS has flagged your account for underreported interest, the bank must withhold 24% of your bonus and interest and send it directly to the IRS.5Internal Revenue Service. Topic No. 307, Backup Withholding That withheld amount shows up in Box 4 of your 1099-INT. You can claim it as a tax payment on your return, but the better move is making sure the bank has your correct information so withholding never starts.
Putting the Bonus on Your Tax Return
Report all interest income, bank bonuses included, on your Form 1040. If your total interest from every source stays at $1,500 or below for the year, enter the amount directly on your 1040.6Internal Revenue Service. About Schedule B (Form 1040), Interest and Ordinary Dividends Once total interest crosses $1,500, you also file Schedule B, which lists each payer and the amount.7Internal Revenue Service. 2025 Schedule B (Form 1040)
People who chase several bonuses a year hit the $1,500 line quickly. Three $300 bonuses plus ordinary savings interest puts you over. The extra form is simple, but forgetting it can delay your refund.
For bonuses under $10 that never produced a 1099-INT, add the amount to your interest total anyway. The IRS may not have a matching form on file, but the income is still legally reportable.
Which Year the Bonus Is Taxed
A bank bonus is taxable in the year it hits your account or becomes available to withdraw, no matter when you opened the account or completed the qualifying steps. Federal tax law counts income when it is actually or constructively received.8Office of the Law Revision Counsel. 26 USC 451 – General Rule for Taxable Year of Inclusion
Constructive receipt trips people up near year-end. If the bank credits your bonus on December 31, 2026, it is 2026 income even if you don’t touch the money until January. The IRS considers you in receipt the moment the funds are available to withdraw, not when you actually withdraw them.
The reverse works too. If you finish the bonus requirements in November but the promotion’s terms say the bonus posts in January, you generally don’t owe tax until that next year. The fine print controls the timing, so read it before year-end.
Non-Cash Bonuses and Referral Payments
Some banks hand out tablets, headphones, gift cards, or small appliances instead of cash. Those are taxable too. Publication 550 bases the taxable amount on the bank’s cost, not the retail sticker price.1Internal Revenue Service. Publication 550 (2025), Investment Income and Expenses A speaker that retails at $199 but cost the bank $120 wholesale is $120 of income to you.
Publication 550 also sets reporting floors on these items. For deposits under $5,000, items valued above $10 at the bank’s cost must be reported as interest. For deposits of $5,000 or more, the floor rises to $20.1Internal Revenue Service. Publication 550 (2025), Investment Income and Expenses Below those amounts the bank need not report the gift, but the value is still technically income to you.
Banks sometimes classify non-cash rewards as miscellaneous payments and report them on Form 1099-MISC instead of 1099-INT. Either way, the value is ordinary income on your return.9Internal Revenue Service. Publication 525 (2025), Taxable and Nontaxable Income
Referral bonuses sit in a similar spot. A $50 or $100 payment for sending a friend to open an account isn’t really interest on your deposit, so some banks report it on Form 1099-MISC or 1099-NEC rather than 1099-INT. The tax result is the same for you: ordinary income, fully reportable. Just note which form you receive so you put it on the right line.
If the Bank Takes the Bonus Back
Banks usually require you to keep the account open and funded for a set period, often 90 to 180 days. Close early and the bank can reclaim the bonus. If the clawback happens in the same calendar year as the bonus, the bank adjusts the 1099-INT to the net amount and you only owe tax on what you kept.
The headache comes when the bonus posts in one year and the clawback happens the next. You already reported and paid tax on it. The IRS doesn’t let you amend the prior year’s return simply because you later gave the money back. Instead, you look for a deduction in the year of repayment.
For repayments over $3,000, there is a special calculation under the claim-of-right doctrine that often produces a better result.10Office of the Law Revision Counsel. 26 USC 1341 – Computation of Tax Where Taxpayer Restores Substantial Amount Held Under Claim of Right Most bank bonus clawbacks are a few hundred dollars, so this rarely applies. The natural fallback would be a miscellaneous itemized deduction, but Congress made the suspension of miscellaneous itemized deductions permanent in 2025, effective for tax years beginning after December 31, 2025.11Office of the Law Revision Counsel. 26 US Code 67 – 2-Percent Floor on Miscellaneous Itemized Deductions For 2026 forward, a clawback under $3,000 gives you no deduction at all. You effectively paid tax on money you returned. Worth knowing before you chase a bonus with requirements you might not meet.
What Happens If You Don’t Report It
Skipping a 1099-INT is one of the easiest ways to earn IRS attention. The agency receives a copy of every 1099-INT the bank files, and its automated matching system compares those forms against your return. When the numbers don’t line up, a CP2000 notice follows, proposing additional tax, interest, and possibly a penalty.
The accuracy-related penalty for negligence runs 20% of the underpaid tax tied to the unreported income, and the IRS specifically lists “not including income on your tax return that was shown in an information return” as an example of negligence.12Internal Revenue Service. Accuracy-Related Penalty A separate substantial understatement penalty also carries a 20% rate when your total understatement exceeds the greater of 10% of the correct tax or $5,000.13Office of the Law Revision Counsel. 26 US Code 6662 – Imposition of Accuracy-Related Penalty on Underpayments Most stand-alone bonus omissions won’t hit the $5,000 floor, but combined with other missing income they can.
On top of penalties, the IRS charges interest on any unpaid balance. The underpayment interest rate for the first quarter of 2026 is 7% per year, compounded daily, and it accrues from the original due date of the return until you pay.14Internal Revenue Service. Interest Rates Remain the Same for the First Quarter of 2026
One practical note: taxes aren’t withheld on bank bonuses unless backup withholding applies, so the full tax bill shows up when you file. For a reader collecting one or two small bonuses, existing paycheck withholding absorbs it. Someone pulling in several thousand dollars of bonuses in a year could trigger an estimated tax underpayment penalty and should either make a quarterly payment or bump up W-4 withholding at work to cover the gap.15Internal Revenue Service. Underpayment of Estimated Tax by Individuals Penalty
State Taxes
Most states with an income tax treat interest the same way the federal government does, so your bank bonus is almost certainly taxable at the state level too. State rates on ordinary income run from roughly 2% to over 13%, depending on where you live and your bracket. A handful of states have no individual income tax at all, so residents there owe nothing beyond federal. Check your state’s tax authority if you aren’t sure.
