Mark Kohler explains that one in three Americans earn side-hustle income they don't realize counts as self-employment for taxes. Consultants, 1099 contractors, realtors, freelancers, Uber drivers, and online sellers all report this on Schedule C, not a W-2.

Now, what does self-employed really mean? 1 in 3 Americans have side hustle income. Well, that is self-employment. That's a Schedule C on your 1040, and it can take lots of shapes and sizes. A consultant, a 1099 contractor, a realtor, a freelancer, someone selling products online, driving Uber, running a storefront, operating a restaurant. The list goes on and on. The key is that you're generating income for yourself, not on a W-2.
