I work and live in different states, but those states have a reciprocal agreement: any local taxes I pay to my employer's state are a credit for my home state income taxes. Last year a Turbotax glitch (combined with my inattentiveness!) accidentally marked my local taxes as belonging to my home state – this made it appear like I paid significantly too much for local taxes. I filed and happily but surprisingly expected a large refund. Instead, I received a more typical refund and a letter from the Dept. of Revenue showing that the state had amended my return to match their records and that no further action was required. My taxes could be this simple every time. What a bummer that they aren't.
