These threads always make me a tad nervous, because I worry that someone who really needs an extra $150 in instantly spendable cash a month might be very adversely impacted by a change in tax laws that suddenly increases their income tax. The "fiscal cliff" almost eliminated the child tax credit. That would have increased people's average tax bill by $1000 per child.
Do you have a source for this? All the information I've found says the Child Tax Credit was extended for 2013 and beyond.
