The thought of a kidnapper inquiring about the child's social security number in the ransom note is pretty good dark humor. But I think the IRS has some restrictions on who you can claim as your dependent.
To claim someone as your dependent child, they must be either:
- Your son, daughter, stepchild, foster child, or a descendant (for example, your grandchild) of any of them; or
- Your brother, sister, half brother, half sister, stepbrother, stepsister, or a descendant (for example, your niece or nephew) of any of them.
To claim someone as your dependent relative, they must be either:
- Your child, stepchild, foster child, or a descendant of any of them (for example, your grandchild). (A legally adopted child is considered your child.)
- Your brother, sister, half brother, half sister, stepbrother, or stepsister.
- Your father, mother, grandparent, or other direct ancestor, but not foster parent.
- Your stepfather or stepmother.
- A son or daughter of your brother or sister.
- A son or daughter of your half brother or half sister.
- A brother or sister of your father or mother.
- Your son-in-law, daughter-in-law, father-in-law, mother-in-law, brother-in-law, or sister-in-law.
