Michael, first off, wait until this week...I'm almost positive the State will clarify it.
But, it's pretty clear -
"NRS 76.020 “Business” defined.
1. Except as otherwise provided in subsection 2, “business” means:
(a) Any person, except a natural person, that performs a service or engages in a trade for profit;
(b) Any natural person who performs a service or engages in a trade for profit if the person is required to file with the Internal Revenue Service a Schedule C (Form 1040), Profit or Loss From Business Form, or its equivalent or successor form, a Schedule E (Form 1040), Supplemental Income and Loss Form, or its equivalent or successor form, or a Schedule F (Form 1040), Profit or Loss From Farming Form, or its equivalent or successor form, for that activity;"
If you're an independent contractor, you'll be (or should be) filing taxes taking mileage deductions, etc. Uber will be sending you a1099 at years end so you have to declare the income. There's a whole section on these forums regarding that. That's the "Schedule C" they're mentioning.
So, let's wait together until later this week and see what the State decides.
