Paypal business merged ALL the 2015 payments made to my paypal account mixing business (taxable) with private (non -taxable) payments. Under the old system ( Paypal classic) I could select under payments received, which email address received what payment. That way I could separate the payments from my (money loosing) hobby and the income from my business.
I have ot say that it is more and more likely I will switch to accepting Credit Cards directly on my website rather than deal with Paypal. I wish the developers ACTUALLY NEW how to run a business and what features not only LOOK nice but actually provide a valuable service to the consumer.
