State tax filing

Yes...as a resident of KY, you must file a KY tax reporting all of your income, even from TN

KY would allow a credit if your paid a tax on that to TN...but since TN doesn't tax wages, then KY gets to tax it all.

This is not unusual...all income taxing states operate the same way

...............(with some few exceptions for reciprocal-tax states)
