For each state here are the rules for taxable social security. TurboTax will handle this on both state returns and you can double check by reviewing the state returns (see information below).

1. Kentucky (KY) - If you have reported social security income on federal Form 1040, line 5b, you can subtract this amount on Kentucky Schedule M, line 10.
2. North Carolina (NC) - All Social Security retirement benefits are exempts from income taxes.
