For those of you who collect sales tax from your customers, how does it work? Meaning, say you do lawn apps, do you just tax the product used or product and labor used? I saw a bill from one of these companies and they tax for the whole thing even the $3.00 fuel surcharge they are tacking on. Can this be OK? I always thought you could only tax product or service but not both at the same time.....Am I wrong? I don't see how they can tax fuel surcharge? What do you think?
