Revenue Is Not the Number in Your Bank Account
As a gig worker, you are a small business whether it feels that way or not. Driving 100 miles to earn $100 is not a win if gas and depreciation ate $50. Compare app payouts to gross vs net the same way you would a salary offer—then subtract costs the app never shows.
The Self-Employment Tax Nobody Mentions in the Onboarding Video
W-2 employees split payroll taxes with an employer. You play both roles, so 15.3% hits your net self-employment income before federal income tax. That is not a penalty—it is how Social Security and Medicare get funded—but it is the reason a "good week" on the app can still feel thin.
