Did you have a dependent care FSA at work to pay for expenses pre-tax? That would be listed on your W-2 in box 10. If you had a $5000 FSA, that uses up your eligibility to also claim the dependent care credit. Since the maximum expenses for the credit are $6000 with two or more children, a $5000 FSA would leave you with $1000 of leftover expenses to count toward the credit.
Your child care expenses are limited to your earned income, or if you are filing jointly with your spouse, they are limited to the earned income of the lowest earner.
