I am still a little new to all this but I wanted to get your advice here. I just found two great suppliers on ebay for office supplies and dvds. I started selling them on Amazon and then shipped through ebay. Depending on the item I have been getting $5-$15 roughly. I have started selling ALOT and starting to make a nice coin. So far it is going smooth. I started thinking about taxes (I live in Illinois) here. Is it a nightmare trying to do taxes this way? Should I do taxes? Should I get an EIN number? Is it better to do this 1099?
