The child tax credit amount calculator will guarantee the most money back to you will be the route automatically taken, as their 100% biggest refund guarantee is no idle boast.
There were some changes in 2009 that saw the threshold of 12,500 move to 3,000 which has made it much easier to qualify for the refundable additional child tax credit amount.
It should be noted that the otherwise child tax credit amount is phased out for those taxpayers with a modified adjusted gross income above certain thresholds. If this is indeed the case, then the amount of the child tax credit will be reduced (not below zero) by $50 per $1,000 your modified adjusted gross income surpasses the threshold amount.
