Why the IRS treats cash back as a rebate
Purchase-tied rewards are classified as an adjustment to the purchase price, not gross income. This includes cash back, so there’s no income tax. For example, if you spend $1,000 on a card that earns 5% cash back and you get $50 back. Your real cost was $950, not $1,000. This tax treatment traces back to a 2010 IRS ruling.
When cash back or a bonus is taxable
The test is simple: did you have to spend money to get it?
| Reward type | Taxable? |
|---|---|
| Cash back from spending | No |
| Sign-up bonus (spend required) | No |
| Referral bonus | Yes |
| No-spend account bonus | Yes |
Alternatively, sign-up bonuses that require you to spend a certain amount within a specific time frame are still a rebate since they’re tied to purchases.
Reporting cash-back rewards on your taxes
Starting with the 2026 tax year, issuers only have to send a 1099-MISC for taxable rewards of $2,000 or more, up from $600 in 2025. You still owe tax on taxable rewards even if you never receive a 1099 form.
Business credit card cash back: a different rule
For a business, cash back doesn’t show up as separate income; it lowers your deductible expense instead. For example, if you spend $1,000 on office supplies and get $50 back, you can only deduct $950 on Schedule C, not the full $1,000.
Cash-back apps and gift cards
The same rebate logic covers shopping-portal cash back and gift-card rewards: if you had to make a purchase to earn it, it’s a discount, not income.
