Downvote and remove if inappropriate. I am selling a large chunk of cards, and due to being lazy and not wanting to wait to piece it all out, decided to take less profits and just buylist to cardkingdom. I am just curious as to how taxes work on large sales, like if its a self reported thing at the end of the year or something like that, or if there will be a form that needs filled out. Or if i dont even have to do anything at all. Not a huge amount, only around 2500 dollars. Live in pennsylvania if it matters.
