eBay fee processing

[l72840]

Why is it that eBay adds item purchase price, insertion fee, final value fee, shipping fee all together before calculating sales tax???? Sales tax should be only on item purchase price. I purchase a label from eBay, then on my own I purchase album shipping box, bubble wrap, tape, fragile stickers, my time and effort to ensure the best possible packaging for my buyer, and I then go to the USPS office. And eBay collects all the fees and is in effect stealing from we the sellers.  I also have an issue with funds owed to me from eBay for erroneous charges. They said 1-2 days processing time, that was on June 30, 2025. 1-2 days ended 9 days ago. How can we, the sellers, dispute these fraudulent activities exhibited by EBAY???

Sales tax is calculated based on the laws of the state the item is being delivered to. Some states include shipping in the calculation, some do not.

eBay fees are calculated based on the entire amount the buyer pays, including sales tax, if any.

eBay gets to decide how fees are calculated. Individual sellers get to decide whether it makes sense to list an item on eBay or not.

eBay could calculate fees in a different way, but then the fee percentage used would be different in order to bring in the same amount of revenue.

Some states also require the sales tax to be applied to the shipping charge.

Like it's been forever, their fees are based on the total amount the buyer pays.

insertion fees, FVF are deductions, they are not added to the value of the item to calculate the sales tax
