I'm still around

Hi guys, sorry for not posting in forever. I've been busy trying to do the photography thing. I already got one gallery that wants my tiny planets and today I just talked to another gallery owner that seems interested in them. I have a meeting with him this thursday so I hope I get in. I really hope this is the year of photography for me. Oh, and I have a question for ya. I have yet to register a business name with a tax ID and all that and actually file with the government . Will I get in trouble if the IRS ever audits me from all the images I've already sold?
