If my wife's company offers dependable care FSA and she can contribute $5,000, can we contribute and claim dependent care FSA through her so as to get the benefit of the full $5,000? Yes you can.
Expenses for day-care are invoiced in my name but paid through her checking account. Doesn't matter since you are a married couple.
Separately, our day-care expenses are higher than the $5,000 threshold, can we also, therefore, claim childcare credit on the remainder of the expenses after claiming the first $5,000 through dependent care FSA? Since you have only one child the max the credit is on is $3000 so the FSA is used only ... there is nothing more for you to take the credit on.
