How do I collect the right amount of taxes on eBay?
eBay has built-in sales tax collection functionality that you need to enable and configure on your own.
Our app then allows us to download your order history and report on the sales tax you're collecting via eBay and then we assign the collected taxes to the proper jurisdictions for each state to aid in filing.
Collecting on eBay isn't an exact science because eBay does not allow for multiple rates in a single state, but we have tips for choosing a rate for your eBay accounts here.
