Form 309 california

According to the instructions for Arizona Form 309, as an Arizona resident, nonresident returns filed with the following states DO NOT QUALIFY for the credit (for tax paid to another state) on the Arizona return: Alaska, California, Florida, Indiana, Nevada, New Hampshire, Oregon, South Dakota, Tennessee, Texas, Virginia, Washington and Wyoming. You may be able to claim a credit for taxes paid to Arizona on the nonresident return filed with any of those states listed above.

This situation is the reverse of the situation for most states, where you prepare the nonresident return first and then take any credit for tax paid to that state on the resident return.

See this thread for further discussion of this issue. You can choose to prepare the Arizona return before the California return and then take the credit on the California return instead.
