Bank Bonus Taxes: A Complete Guide to 1099-INTs on Sign-Up Bonuses

Bank sign-up bonuses are one of the easiest ways to put a few hundred dollars back in your pocket each year — but they come with one catch many people overlook: they are taxable income. Unlike most credit card welcome bonuses, which the IRS generally treats as a non-taxable rebate when earned through spending, the cash you get for opening a checking, savings, or money market account is typically reported on Form 1099-INT.

Whether you earn one bonus or several over the course of the year, understanding how the tax treatment works will help you avoid surprises at filing time, plan your real after-tax return, and stay fully compliant. This guide walks through the rules, the forms, the math, and the most common questions we get from readers.

Are bank account sign-up bonuses taxable?

Yes. Bank account bonuses are taxable income. Banks commonly report cash bonuses for checking, savings, and money market accounts on Form 1099-INT because the payment is tied to a deposit account. IRS Topic No. 403, Interest Received says taxable interest must be reported even if you do not receive Form 1099-INT, and IRS Publication 550 explains that deposit-account gifts or services may be reported as interest.

The same idea applies whether the payment is called a bonus, premium, or reward: if it is paid for opening or maintaining a deposit account, plan for it as taxable interest unless your tax professional tells you otherwise.

In practical terms: if you opened a checking account and received a $300 cash bonus for completing the qualifying activity, that $300 is treated identically to $300 of interest you earned on your savings — it is ordinary income, taxed at your marginal federal income tax bracket and (if applicable) your state income tax bracket.

How banks report bonuses: 1099-INT vs. 1099-MISC

Most checking, savings, and money market bonuses arrive on Form 1099-INT, but some promotions may be reported on Form 1099-MISC or, less commonly, Form 1099-NEC. The form affects where you enter the income; it does not make the bonus tax-free.

• Form 1099-INT — Used by the vast majority of banks for traditional checking, savings, and money market account bonuses. Banks are required to issue a 1099-INT to any account holder who received $10 or more in combined interest and bonuses during the calendar year. Lower-dollar bonuses may not generate a form, but they are still taxable.

• Form 1099-MISC — Sometimes used for promotions that are not tied to an interest-bearing deposit, such as a referral bonus or a stand-alone promotion. The threshold for issuing a 1099-MISC is $600 or more in a calendar year.

• Form 1099-NEC — Rare for retail bank bonuses, but occasionally seen for business banking referral programs.

A few practical implications:

• A $300 bonus on a checking account reported on 1099-INT is taxed exactly like ordinary interest.

• A $300 referral bonus reported on 1099-MISC (Box 3, "Other Income") is also ordinary income, but it shows up on a different line of your return.

• Schedule B is usually required if you have over $1,500 of taxable interest or ordinary dividends in a year, or if another Schedule B trigger applies, such as certain foreign-account or trust questions. Most tax software will generate it automatically after you enter each 1099-INT or 1099-DIV payer and amount, but you should still make sure every bank bonus and interest source is included.

How much tax will you actually pay?

Because bank bonuses are taxed as ordinary income, the cost depends on the marginal federal rate that applies when the bonus is paid, plus any applicable state or local tax. The examples below are illustrative and assume the bonus falls into the marginal bracket shown.

These are illustrative; your actual result can change with deductions, credits, filing status, state rules, and whether the bonus pushes you over another threshold. High-income filers should also watch for the 3.8% Net Investment Income Tax and Medicare IRMAA thresholds. Use our Bank Bonus ROI Calculator to estimate your after-tax annualized return on any specific offer.

The takeaway: a headline $500 bonus is rarely $500 in your pocket — but even after tax, the annualized return on a short-term bank bonus can still beat what a standard high-yield savings account pays on the same balance.

What if you don't receive a 1099?

Two common situations come up:

1. The bonus was less than $10. Banks aren't required to issue a 1099-INT below this threshold. The income is still legally taxable and should be included with your taxable interest, even without a form. If Schedule B is required for your return, include it there; otherwise it generally flows directly to Form 1040, Line 2b.

2. You received the bonus but no form arrived by mid-February. Most institutions postmark 1099s by January 31 of the following year, with a final IRS deadline of February 28 (paper) or March 31 (electronic). If your form is missing:

• Log into your online banking portal — most banks now post 1099s digitally before mailing.

• Contact the bank's customer service to request a duplicate.

• If all else fails, report the income from your own records using the bank name and amount paid. Use the EIN only if you have it or your software requires it.

The IRS receives a copy of every 1099 issued in your name. If you omit reportable bonus income that the bank reported, you are likely to receive a CP2000 underreporting notice 12 to 18 months after filing.

How to report bank bonuses on your tax return

For most filers, the process is straightforward:

1. Gather your forms. Collect every 1099-INT and 1099-MISC you received, along with year-end statements from any account that paid a bonus or interest under $10.

2. Report the income in the right workflow. In tax software, this usually means entering the form details rather than choosing a tax-return line yourself. 1099-INT amounts are taxable interest and generally flow to Form 1040 as interest income; if Schedule B is required, the software lists each payer in Part I. 1099-MISC Box 3 amounts generally go through the software's other-income workflow and flow through Schedule 1 to Form 1040.

3. Match the EIN and amounts exactly to what the bank reported. If you believe a 1099 is incorrect, request a corrected form from the bank rather than ignoring it.

4. Keep records for at least three years (the standard IRS audit window), or seven if you want to be conservative.

Most tax software handles Schedule B automatically. Enter each 1099-INT, 1099-DIV, and taxable interest amount without a form, then answer the foreign-account and trust questions based on your actual accounts. The software should attach Schedule B when a trigger applies, such as more than $1,500 of taxable interest or ordinary dividends.

What about credit card welcome bonuses and brokerage bonuses?

The treatment differs depending on the product:

• Credit card welcome bonuses earned by spending. The IRS generally treats rewards earned through purchases as a non-taxable rebate or purchase-price adjustment, and issuers do not typically issue a 1099 for spend-based welcome bonuses. The rebate treatment applies to ordinary spending; it does not extend to every card-related payment.

• Credit card bonuses without a spending requirement. Rare, but if a card simply pays you cash to open it with no purchase activity required, the IRS may treat that portion as taxable income. Some issuers do report this on a 1099-MISC.

• Brokerage account sign-up bonuses. Typically reported on 1099-MISC, or in some cases 1099-INT. "Free stock" promotions are usually reported at the fair market value on the day the shares are credited.

• Referral bonuses. Almost always taxable. Banks typically issue a 1099-MISC once cumulative referrals reach $600.

When in doubt, look for a year-end statement from the bank or brokerage labeled "Tax Documents" — it should show the tax forms the institution issued for your account.

Recordkeeping best practices

A simple spreadsheet kept throughout the year saves hours at tax time. We recommend tracking:

• Institution and product name

• Account-opening date and bonus posting date

• Bonus amount and form type received or expected (1099-INT, 1099-MISC, 1099-NEC, or none)

• Bank EIN, if it appears on a tax form or your software asks for it

• Account closure date, if applicable

• Any fees paid to maintain the account — these are not deductible, but they affect your true return

Pair this log with our Bank Bonus ROI Calculator to translate each row into an after-tax APY, which makes it easy to compare bonuses against simply leaving the money in a high-yield savings account.

Frequently asked questions

Will earning bank bonuses affect my Social Security or Medicare benefits?

Bank bonus income is unearned interest, so it does not count as wages for Social Security benefit calculations, FICA taxes, or the Social Security earnings test. It can still matter for taxes: interest can increase the income used to determine how much of your Social Security benefit is taxable, and it can increase MAGI for Medicare IRMAA thresholds. A few hundred dollars usually will not matter, but people near a threshold should check.

Can I deduct fees I paid to keep an account open?

Personal account maintenance fees are generally not deductible for individual taxpayers under current federal tax law. They simply reduce your effective bonus.

What if a bank closes my account before paying the bonus?

No bonus, no taxable income. Document the closure for your records in case the bank issues a 1099 in error.

Are state tax rules different?

Most states tax interest the same as the federal government. A handful — Alaska, Florida, Nevada, New Hampshire, South Dakota, Tennessee, Texas, Washington, and Wyoming — have no state income tax on interest. Always check your state's rules.

Do I need to make estimated tax payments?

For most people, withholding from regular wages covers a few hundred dollars of bonus income. If you earn several thousand dollars in bonuses and have no other withholding adjustments, consider making a quarterly estimated payment to avoid an underpayment penalty.

Bottom line

Bank sign-up bonuses are one of the few forms of "found money" the average consumer can earn — but they are real income in the eyes of the IRS, and they should be planned for like any other income. Knowing the rules ahead of time means:

• No surprise tax bills in April.

• A more accurate picture of which bonuses are actually worth your time after tax.

• Confidence that your return is complete, even if a 1099 doesn't show up in the mail.
