Other retailers are going to have to start charging sales tax also.
Look states loose a lot of revenue from not being able to collect taxes from internet sales vs local retailers. They need to make this money up somewhere else so they are going to have to raise taxes/fees on other thinks like vehicle registrations, court costs, etc.
"Sales tax" is supposed to pay for infrastructure consumed by the act of commerce. Roads, traffic lights, police and so on. City subsidies for malls and shopping centers, crap like that.
When the act of commerce does not involve traditional commerce avenues, the State does no work for the tax and no communal resources are consumed. The first counter-argument typically made was that the UPS driver will consume roads/traffic/police/etc while delivering the product. However, the UPS driver is already paying commercial-use vehicle registration, and often times multi-state registration for the long-haul ground services.
The simple fact remains that e-commerce consumes fewer state resources than traditional commerce, and sales tax is ever and ever inflated to be the catch-all funding source for all sorts of slush funds.
Our sales tax in AZ has recently paid for a bull-scat light rail system, sports stadiums, and revamped shopping districts (for Walmart, Best Buy, and the other big box retailers who benefit from those sales taxes and hate the massive price differential between the online free market and the bullscat sales tax market).
I'm of the opinion that CONSUMERS of those facillities need to pay for them.
I deliberately purchase things where I pay no sales tax so that I don't fund them.
Taxes need to return to ethical justifications. "No taxation without representation" doesn't work in a mutated Republic-become-Democracy. We need "No taxation without consumption, taxation for consumption."
I might support a sales tax on online purchases that is 10% the rate of the conventional face-to-face sales tax. Here in AZ, we're just shy of 10% sales tax, so a 1% online tax... I'd accept that. That's justifiable. 10% on the purchase when the State does NOTHING is pure highway robbery.
If States continue this trend, I'll fund the used market or grey market activities.
