Sales tax.

Can Ebay tax me on shipping costs along with the purchase price?

It is your state that determines this. 

And yes most states apply sales tax to the entire transaction shipping included.

Hi @50sboy 

That depends on the sales tax laws of the state the item was sent to. Most states require eBay (and all online marketplaces) to collect sales tax on shipping plus item price.
