How Are Bank Bonuses Taxed?

Bank bonuses are taxed as ordinary income. The IRS treats a bonus the same way it treats the interest your savings account earns. It does not matter whether the bank calls it a "bonus," a "cash reward," or a "promotional credit." If the bank paid you money for opening an account or meeting a requirement, that money is taxable.

When you earn $10 or more in combined bonuses and interest from a single bank in one calendar year, that bank is required to send you a 1099-INT. This form shows up in your mailbox or online account between January and mid-February the following year. It reports the total amount you earned so you can include it on your tax return. If you earned less than $10, the bank might not send the form, but you are still technically required to report the income.

Your actual tax rate depends on your federal income tax bracket. Most people earning bank bonuses fall somewhere in the 12% to 24% range. A rough rule of thumb is that you keep about 70 to 80 cents of every bonus dollar after federal taxes. State taxes vary. Some states have no income tax at all, which means you keep more. Others add a few percentage points on top. For a $300 bonus, expect to owe roughly $60 to $90 in taxes depending on your situation. The bonus is still worth doing. You are still coming out ahead by hundreds of dollars for a few minutes of work.

Bonuses are taxed in the year you receive them, not the year you opened the account. If you open an account in November and the bonus posts in January, it counts toward the following tax year. This matters if you are earning several bonuses across the end of a calendar year. Keep a simple spreadsheet with the bank name, bonus amount, and date received so filing is easy. Interest earned from a high-yield savings account during the same period gets reported on the same 1099-INT, so both numbers will be combined on one form.

One thing to plan for: if you earn multiple bonuses in a single year, the combined income can add up. Someone who completes five bonuses worth $300 each has $1,500 in extra taxable income. That is not enough to bump most people into a higher tax bracket, but it is enough to create a small surprise at tax time if you did not set anything aside. Some people move 25% of each bonus into a separate savings account as it arrives and use that to cover the tax bill. Others just adjust their W-4 withholding slightly if they plan to rechurn bonuses throughout the year.

None of this changes the math on whether bonuses are worth pursuing. A $400 bonus that costs you $80 to $100 in taxes still puts $300+ in your pocket for opening an account and meeting a hold period. There is no investing, no market exposure, and no scenario where you lose the money you started with. You can browse current bonuses to see what is available right now.
