How the cost works
Nebraska's biggest yearly charge is the motor-vehicle tax, set by the car's original MSRP and its age on a 14-year schedule — it's the same in every county, so it doesn't appear in the table. What changes between counties is the local sales tax (7% here) charged once at purchase. The county treasurer collects everything when you title the vehicle.
