We own a home in both AZ and NC, and have registered cars in both locations. Our time is split equally between the two and only have SS and pension income which is all deposited in NC. Do I need to file a return in both states? We also just put solar on our home in AZ, which of course gives a Federal tax credit, AZ also provides a credit but we currently do not file an AZ return so can't claim the credit. Or can we? I'm pretty sure we are only required to file in NC as that is where we vote and maintain our driver's licenses. My understanding the state credit for solar can be carried over for 5 years. So if we want the credit we would need to change our primary residence to AZ. Am I correct in my thinking? Thank you
