I filed my taxes 2/14, got another (small amount) 1099 misc on 2/15. It is from a company that was in a buyout in 2010. I got one from the old company (By 01/31) and one (on 2/15) form the new company. I included the income already on my sch C just not in the 1099 catagory. Do I need to file a 1040X with the exact same amounts? How will this affect my state taxes? Does the state see all of what is reported on 1099 vs gross sales and rec.? Do I need to file an additional tax return for the (wi) state?
