From the article:
At the moment, states and municipalities are frequently barred by federal law from collecting both access and sales taxes. But they're hoping that their new lobbying effort, coordinated by groups including the National Governors Association, will pay off by permitting them to collect billions of dollars in new revenue by next year.
The fed granted exemptions to let e-commerce get a foothold, at this point its firmly established, there is no justification anymore to leaving the internet tax free. Online commerce is now well established and far past the “incubator” stage.
If the reason for tax exemption was to spur online commerce and give it a break until it was established, which is exactly why it was given exemption in the first place, then its clear that its served its purpose and is no longer neccessary.
There are many taxes I don’t like, but the idea that if you buy or sell online you don’t have to pay or collect sales tax is not one of them. Online is firmly established, there is no reason they should not be collecting and paying the sales taxes like everyone else.
