If you have one child the FSA money you already used is pre-tax. You do not get to double dip and get another $3000 childcare credit on top of that. If you have two or more children in daycare, then you could get up to $1000 of the childcare credit -- the difference between the $5000 of FSA money and the $6000 childcare credit limit for 2 or more children.
