I put the amount of income per state in the correct boxes, and it created the state forms correctly. However on the Multi-State Apportionment Summary it shows CA as 0% -- but that is the state that the client owes. I'm just wondering if the number(s) isn't carrying over to that summary page correctly, or if there is a bigger issue I should be looking for. How important is it to have the Multi-State Apportionment Summary be correct? Is anybody other than my client even looking at that?
"Is anybody other than my client even looking at that?"
The states certainly are going to be looking at that. How are you calculating what they owe the state? Normally that calculation is based on the apportionment factors.
