excerpt:

The original return’s statements regarding part-year residency were not accurate and were inconsistent with our continued payments of Illinois estimated tax, both in the original 2009 return and subsequently,” the form reads. “The amended return makes clear that we were full year residents of Illinois in 2009 and it reports all of our income.”
