Whether or not you receive a tax statement for funds you receive doesn’t actually affect the tax you owe. It’s a big deal in frequent flyer circles that Citibank has in the past reported bank bonuses on a 1099. The IRS knows that value and so consumers have no choice but to report it on their taxes.
This is a big issue for on-demand platform companies like Uber and Lyft, and it’s one reason that some drivers prefer Lyft over Uber: less tax reporting.
