Solved
I work and live in State A but have interests from a credit union in State B. The credit union only has physical branches in State B, and I opened the accounts a few years ago while I lived there. Do I need to file a tax report for State B just because I got interests from the bank in that state?
No, you do not need to file state taxes for the state (state B) your credit union interest-bearing account is in. You will need to file taxes with State A where you live and work.
Here is more information for when one would need to file a non-resident return (a return for a state they do not live in):
