I searched the forum for an hour trying to find this answer, so if the regulars here notice I give my heartfelt apology. Mkay. Two simple questions: 1. When one of my customers orders prints, I order them through Mpix and have them drop shipped to the customer. I pay sales tax to Mpix. I charge Mpix's Print Price x2 + half that result. Should I be charging my customers sales tax if I paid sales tax on the prints already? 2. Does anyone know if Illinois requires you to charge sales tax on the sitting fee? I would contact my business advisor but it's nearly 11pm and I have a customer who needs me to process their order by tonight. :er: EDIT: That formula for what I charge is because I do a 'buy one get one half off' deal. I only sell prints in equivalents of 8x10 sheets.
