The point is, CA government is putting a huge administrative drain on out-of-state retailers to manage CA's state business. If CA wants out of state retailers to collect sales tax for them, they should set it up so it is much less painful for the retailer... better yet, transparent. I would be very interested to hear how the retailers are managing this. CA is so screwed up, I bet many less than trustworthy retailers could pocket much of those funds and CA would never be the wiser.
I dont like taxes on online sales, but the argument that its all that burdensome for companies like amazon to collect, calculate and forward the taxes to a particular state in the days of automated ordering and accounting systems is overstated.
