We ended up owing because my company was acquired and the new company took out less federal taxes. That said, we got to apply our tuition credit to our kids so they are each getting back $1000 more than they planned. And luckily when I saw my new company was taking out less, I started setting aside some in preparation until I could talk to our accountant. I’ve updated my w-4. Another thing that threw us off was that my daughter can’t both be a dependent and get the tuition tax credit at 18, so we lost that for this year.
But my son, who is 19 can do both. Who knows why that is, but that’s what our accountant told us after she had to do some research.
