State tax filing

Your reply is inconsistent.  On the top, you say "yes.  Your liability will be zero, but filing is required.  In paragraph 3, you say "if you had no income while a resident of AZ, including wages, or income from AZ property, then a tax return is not required to be filed.  My taxpayer had NO AZ INCOME WHATSOEVER.  Does she still have to file AZ tax return or not?
