3-part question: (THANKS in advance)!
1.Since using apps like Facebook Marketplace & Offer Up charge me a fee & collect & pay sales tax for the seller, which number is used to determine the $600 threshold (selling price or lesser net amount)?
2. When selling stuff at a loss (used & less than paid) and I receive a 1099-K, do I ignore it under the "occasional yard sale" stipulation, or will there be an offset where I enter amount & show selling at a loss?
3. Does shipping items to multiple states have any influence on filing? (Specifically, I won't be expected to have to file a state tax for each state would I)?
