Can an online business be counted as an extracurricular on a college application

I’m trying to find out if I can put my online business that I started about a year ago on my application for colleges. I’m a junior in high school right now, and the online business is mostly passive income of like 1-2k every month. Would I need to show proof of what I’m doing when I list it in my application? I’m planning on majoring in Business

Sure, you can list it.

Yes, of course it’s an extracurricular. And if you’re hoping to major in business definitely include it on your app.

It looks great on the application!
