While you may be pretty sure, it is an incorrect assumption.
Sales Tax: TX 8.0% (Dallas 8.25%) > IN 7.0% > CT 6.35%
Combined with Texas' relatively high property taxes and likely similar cost of living near Storrs versus highly affluent Highland Park (SMU) and nearby high-end north Dallas communities, Texas, you wouldn't be the first person to naively leap to an assumption no state income tax
absolutely equates to paying lower total combined taxes. Regardless, Lashlee should fare OK with a possible income bump and potential overall COL decrease (depends on where he lived near Storrs).
