<prompt> Human: Back in November 2016 me and a friend partnered up to create an e-commerce business which would dropship merchandise at a good markup. I had 70,000 go through my PayPal account and in turn they sent the IRS a 1099-K form showing all that money received. My partner handled the credit card side of the business through shopify and assured me he was putting away money to cover taxes to pay the IRS when the time came. Lo and behold, he most likely has no money put away for this and never even reported his earnings to the IRS. I would send PayPal money to his PayPal account so he could pay for our substantial advertising costs but despite attempts to contact him, he is not replying to me in my attempts to get the pdfs or proof of payment so I can get my deductions. What are my options here?  <response>: If your business partner cant be found and you got the PayPal 1099-K in your name then treat this as 100 your business. Do the PayPal payments you sent him account for most of the expenses? Write those off. If he opened the Shopify account is his name and hes getting a 1099-K let that be his problem.
