Just a couple of items I picked up in my reading:
Florida - sales tax holiday for clothing, school supplies, etc. with a price of less than $50 beginning 7/23/05 to 7/31/05.
Ohio - delays implementation of destination based sourcing from 7/1 to 5/1/06 and for some, 2008. This has been a big issue in Ohio and further complicates SSTP.
Massachusetts - Happy Meal toys are considered to be purchased for resale as part of the meals and therefore the restaurant doesn't have to pay tax on them. I know you're all breathing a sigh of relief on that one.
And from the "Felony Watch"
Restaurant owner in Florida charged with tax theft
Car dealer sentenced to 2 years
Car dealer OK's plea deal
It seems like it's always car dealers and restaurants that get in the serious trouble on sales tax issues.
