Bank signup bonuses are taxable income; you’ll owe taxes on every dollar at your marginal rate. Credit card welcome bonuses aren’t. The IRS treats them as purchase rebates instead. Always calculate the after-tax value of a bank bonus before deciding if it’s worth it.
Banks are competing hard for new checking accounts right now, and the headline offers look compelling. Chase is dangling $300. Bank of America offers $200. The ads are everywhere.
What the ads skip: the IRS classifies bank account bonuses as interest income. Earn any bonus of $10 or more and the bank will send you a 1099-INT at year-end. That money gets added to your taxable income. If you’re in the 24% bracket, the $300 Chase bonus is actually worth $228. The $200 Bank of America offer puts $152 in your pocket after taxes.
Credit card signup bonuses work differently. Earn 80,000 points worth $800 in travel, or get $200 cash back after hitting a spending threshold, and none of it is taxable. The IRS treats those rewards as rebates on purchases you already made, not as new income. No 1099. No tax hit. You keep the full advertised value.
Before committing to a bank bonus, run a quick calculation: multiply the bonus amount by your marginal tax rate and subtract. That’s your real take-home. In the 22% bracket, a $300 bonus nets $234. In the 32% bracket, you’re keeping $204.
This doesn’t mean bank bonuses aren’t worth it. If you’re already looking for a new checking account and can meet the requirements, a reduced bonus is still money you didn’t have before. But it changes how you compare offers. A $300 taxable bank bonus and a $300 credit card welcome bonus are not the same thing.
Always compare on an after-tax basis. The bank’s $300 headline and the credit card’s $300 headline aren’t playing by the same rules.
