There's still no taxes on Amazon or any other online retailer unless you live in a state with a physical location (shipping center and/or brick-and-mortar store) or your state has the use tax (like Florida). Amazon even has a clear list of the states that get charged a sales tax if the item is bought directly from Amazon or one of its subsidiaries.
- New Jersey
- New York
- North Dakota
Now, the particular bill that is going to put sales tax on pretty much every online order could go into effect as early as October 1. There were some reports of it starting on September 1, however that doesn't seem to be the case as the last several items I've bought on Amazon didn't include a tax.
Ebay is one of the companies fighting the bill, because it could impact any of its sellers that do more than $1 million a year in out-of-state business. It was wanting to put in a stipulation so companies under 50 employees and that do less than $10 million a year should be exempt, just I don't think that was ever successfully added.
Regardless, we should all find out next week what the basic principles of the bill are going to be, just without any specific guidelines. But really, some people are already paying a sales tax on online purchases so they're use to that. Buying pretty much anything local in your state (most states, anyway) already subject you to a sales tax. So this is just to bring further parity to the field and help keep small businesses running, since if everything has a sales tax it'd be easier to buy local and have the item immediately rather than buy online and wait a few days.
