Here's the situation: Company A sells insurance brokerage firm to Company B; the contract to sell states that any and all future commissions payable to Company A will be signed over to Company B. This did occur in 2008 and 2009 - company A received checks from XYZ Insurance company and signed over to Company B. Now fast forward to tax time, Company A ended up with 1099's for income they did not keep. What is the best way to begin resolving this? I can think of several options but they all will take time, certainly longer than April 15th tax filing deadline. Thank you!!
