Situation: Vendor is paid twice a month throughout 2009 as an individual with a SSN on record. The vendor cashes the payments as is. At year end, 1099MISC is sent out with the vendor name and SSN. The vendor now calls saying the 1099MISC is incorrect and supplies new W9 for a corporation. Questions: 1. The payment was made to and cashed by the individual. Should I correct the 1099MISC to the corporation and now not report to the IRS (corp exempt-vendor is not med or legal) even though the payments show as going to the individual? 2. Does the vendor need to provide when the name change and status change occurred? I ask because if the name change does not apply to the whole year, would there be reporting for the time in 2009 that the vendor was not a corp, assuming over $600 was paid to the vendor during that time?
