I’m surprised at the debate about this. FTers are generally so good about understanding rules. As a few have noted, the tax treatment is not hard or unknown. Credit card points awarded based on spending, whether an initial bonus, or just regular point accrual, are considered purchase price rebate, i.e, a price discount, and thus not taxable bc it doesn’t represent income. On the other hand, amounts offered for signing up for a bank account are treated as interest income. That makes sense, bc you haven’t bought anything to offer a discount or rebate on; rather, you’re being paid (in points rather than money) for giving the bank the use of your money, which is exactly what interest is in the first place.
