Well I found out that when you marry and get a ready made family (step Children) I went from owing an extra 1-5k to getting a refund of more than I payed in. Im pretty sure that wont be happening again next year as the job move I just made pretty much doubled my yearly bring home.
I had been there..having 3 step kids on taxes with previous credits while I was making less. This year when we filed we had gone up enough truly our tax refund was cut in half - then DHS reached in for child support that was just paid off and took well over half of that.
