Under normal circumstances, no credit rewards, including sign-up bonuses, have to be included in your taxable income when filing taxes. The reason is that you have to first spend money on purchases to get the reward, which allows the rewards to be treated as nontaxable discounts or rebates. One exception involves credit cards that give you a signup bonus even if you don’t use the card to make any purchases. Since you haven’t bought anything, the bonus can’t be considered a rebate, making the income taxable. The Amazon Prime Rewards Visa Signature Card is an example of such a card because it gives you an instant Amazon gift card. Don’t worry, though — you only have to declare instant bonuses when they exceed $600. That’s the threshold for issuers to send out Form 1099-MISC, notifying you and the IRS about a taxable bonus. The Amazon gift card amount is below the $600 limit, so your CPA is likely to ignore the bonus. In the unlikely event you receive a 1099-MISC form declaring your bonus reward, you’re safer including the amount in your annual taxable income. It’s a much better solution than suffering through an audit or penalty for underreporting income.
