Should I include my stepfather's income on the FAFSA?

Yes, you should include your stepfather's income on the FAFSA if your parents are married. The FAFSA requires information from both biological and stepparents if they are part of your household. If your parents are divorced or separated, you only need to report the income of the parent with whom you lived the most during the past 12 months. Always check the latest guidelines on the FAFSA website for specific situations.
