I raised this yesterday, however, I cannot find the feed. I live in Missouri and own stock in an S-Corporation in Iowa. My only involvement with the S-Corporation is owning the stock and collecting the income. The K-1 information I received from the S-Corporation includes information that identifies some of the income as "Iowa Source Income". Am I required to file an Iowa income tax form as well as Missouri? Or can I include all of the income on my Missouri form and call it a day? Thanks in advance for any help that can be offered.
