I don't see much impact on PayPal or Venmo. But I do see a significant impact on individuals. No one keeps their receipts for things they bought years ago. At a minimum, the limit should be a lot higher than $600. Maybe back to the $20,000 threshold. If you're going to sell as a business, you sure have to sell more than $20,000. If you're selling "yard sale" stuff, it's unlikely you'll reach $20,000.
When this 1099 reporting started $600 was a lot. Today, it's not much but they've never upped that limit.
