I live in Florida and do not get charged digital tax on anything but my ONE purchases and even then it's only about $1.50 for full price $60 games. It just doesn't make sense to me why iTunes, PS3, PS4, and 360 don't while the ONE does. Although it is Florida, where weird things go to happen.
So strange. Im also in FL and like I said no charge for me. Im guessing based off what previous poster said, its because there isnt a Microsoft distribution center here.
Thats why we pay taxes on Amazon now. They are building that distribution here in Tampa I believe.
