to get $2500 back. It has nothing to do whether you have job or not. I know what you are talking about. I don't remember the detail. I do know it is another tax credit for child care, different from flexible spending account. (Normally, for people have flexible spending account, after calculation, they won't be able to get this tax credit. At least, not me :-()
I highly recommend you buying a tax-return software to do your family income tax.
