Not sure if this is the correct spot for this type of question. My apologies if it's not. I was wondering what are the necessary steps to make the transition from being a casual ebay hobby seller to becoming a sports card/memorabilia business? I know there are many here who have businesses on ebay and I'm hoping they can share their knowledge.

If I decide to sell my collection in 2021 on ebay, how would this be classified? Can I become a business and pay taxes as a business or do I have to pay taxes as a hobby?

If it matters, this would be something I do in my spare time and I suspect it would take several years or longer to liquidate everything. And I don't rule out continued buying along the way as a way to make a few bucks as I enter retirement.

Any tips would be greatly appreciated.
