Okay, I'm super new to driving, even more new to these forums, and I have next to zero financial/tax experience. Upon searching around these forums, everyone seems to be asking very specific questions. For someone who is just starting out, what are the basics I need to know about taxes? I've heard people mention saving 20% of your revenue from Uber but I have no idea what that means. What do I need to be doing? Do I need to be tracking mileage/gas receipts/etc.? Someone pretty please break it all down for me.
