This was the first year I’ve had to pay an underpayment PENALTY. The program indicated that the penalty was due because I didn’t have enough state taxes withheld during the year.
I’ve since adjusted my withholding with my employer and paid the penalty. I paid this because I didn't want the penalty to increase any further while I tried to figure this out.
The other day, I received a check from the state returning the full $180. I’m not sure if the software is handling this correctly, but that’s been my experience.
