Anyone have any information or know where I can get information on taxes. I am a website designer, and I know I need to start collecting taxes (if the client decides to write them off). I live in Illinois, if that makes a difference. The reason is, I know that when dealing online, sometime the rules change. For example, to my knowledge if you sell products online you only have to claim a sales tax (charge a sales tax) to the buyer if they live in a state where you have a facility (aka where you are selling from).
