Do you report both parents' income on the FAFSA if your parents were never married?

Yes, if your parents were never married but are both living together, you should report both parents' income on the FAFSA. If they are separated or divorced and do not live together, you only need to report the income of the parent you lived with the most in the past 12 months. If that parent has remarried, you must also include your stepparent's income.
