Taxes and Auction Site Question

[lug-nut]

So I'm getting ready to sell off a big ticket item that will exceed ebay's/irs' $20,000 gross sales portion of the 'tax rule' but not the 200 yearly sales 'tax rule'... yet but I will stop before I get to that level.

Rule listed on ebay: Form 1099-K is an IRS information return that includes the gross amount of all payment transactions you received within a calendar year. The purpose of the form is to help improve voluntary tax compliance. We'll provide you with Form 1099-K by January 31st each year if you're a managed payments seller who has received payments above the minimum IRS reporting thresholds in the previous calendar year:

You received more than $20,000 in gross payments, and
You had more than 200 payment transactions


For you tax and major selling experts:

As I read the requirements, I can safely expect to NOT BE REQUIRED TO CLAIM THIS SALE ON MY TAXES, if I only meet one of them, correct?

Do Auction Houses like the ones mentioned on this site have the same requirement?

Additionally, I'd love to sell the card on the b/s/t to a fellow collector but know the exposure comes from ebay or another large auction site.

I want to sell for the most money and the best overall deal to the buyer, knowing there's a good possibility he/she will have to pay sales tax and I will have to pay sellers commission unless sold on the b/s/t.

Thanks for any info.
