Hey, I live in the US. I started a little side project near the end of last year and made around $15k. I received all payments through PayPal. How do I do my taxes on this? What forms do I need, etc? I know I can subtract out the PayPal fees and also subtract out the money that I paid for help (business expenses, outsourcing, etc.) I've always had corporate jobs where I get a tax statement and everything is all easy cuz taxes are taken out, etc. I've never done the self-employment thing before. Also, if I continue this this year, can I get Cliffs Notes on how to pay estimated self employment taxes? Please note I'm not looking for answers like "lol, who cares, it's PayPal, just don't declare it." edit - I forgot to mention, it's all in my personal name. I had no idea if I was going to make any money or not so I didn't want to go to the trouble of starting a business and spending that money only to end up not making any money. Thanks.
