State tax filing

It depends.  Most states use your federal Adjusted Gross Income (AGI) as the starting point for calculating state taxes.   For example, New York starts withe federal AGI and calculates New York tax based on the total federal AGI after some adjustments.  Actual New York tax is calculated as percentage of that total.  What you're seeing is probably correct, but I can't say for sure without knowing what state it is.
