After you file

I did e file for my friend's state taxes, one for California and another for Arizona. I paid $25 for each state. How come I was still charged for another $48.45 for Arizona State filing?

Does this explain it?

It sounds like you used desktop software.   If your desktop product included 1 state program, then there is another $45 to download a second state program.   Then there is a $25 state efile fee for each state return (except no state efile fee for NY).
