75 million Americans run small businesses from an app, and fewer than 1 in 5 file taxes like a business. You drive for Instacart, DoorDash, Uber, Walmart, and more; you cover the gas, the gear, and the tires; you pay platform fees every shift.

Gig workers deserve to earn the most. These are business expenses, and filing them right can save thousands a year.
