You must meet several criteria to qualify for the child and dependent care credit. To qualify, you must meet all of the following: 1  You (and your spouse, if you are married filing jointly) must have earned income for the tax year.  You must be the custodial parent or main caretaker of the child or dependent.
Generally, in order for someone to claim a child as a dependent on their taxes, a parent must provide at least 50% of the child's financial support during the tax year. For couples who are still married and living together, claiming kids as dependents is usually a slam-dunk. Using this form, the custodial parent can relinquish the exemption for one year, a number of years, or forever, depending on what the parties agree to. 2  If you relinquish the exemption, you are also relinquishing eligibility for the child tax credit.
