I was in the same situation as Brandon A but quite different results.
First, I was told that if it appears that I would owe money, I would have my taxes done before the deadline.
What actually happened was i did, in fact, owe money and my taxes was not completed until a day after the deadline and was told that I owed a significant amount of money.
I later had another tax service look at it and was determined that I actually deserved a refund.
Contacting Abbot about this I received zero response. Not a fan.
