The amount of pre-tax dollars from your employer to pay for childcare cannot be used for the Child and Dependent Care Credit. This amount is reflected in Box 10 of your W-2s.
The credit is based on a maximum of $8,000 spent on childcare and is reduced for every dollar of childcare you paid using pre-tax income. Since your dependent care from your FSA exceeds $8,000, you cannot claim the credit.
