Who Can You Claim as a Dependent?
"Can I claim my girlfriend? My 24-year-old who still lives at home? My mom?" These are the questions that flood r/tax every year, and the answer is never a simple yes or no. Here are the two types of dependents and exactly what it takes to claim each one.
Two categories
Child / Relative
Each has its own tests
Child tax credit
$2,200
Per qualifying child under 17
Key child test
Support
They don't pay 50%+ of own costs
Key relative test
Income
Under a low threshold
Why Dependents Matter
Claiming a dependent unlocks real money: the $2,200 child tax credit per child under 17, the dependent care credit, head-of-household status, and more. That's why people care — and why getting the rules right matters.

Qualifying Child: The Tests
A "qualifying child" must meet all of these:
- Relationship — your son, daughter, stepchild, foster child, sibling, or a descendant of any of these.
- Age — under 19, or under 24 if a full-time student, or any age if permanently disabled.
- Residency — lived with you more than half the year.
- Support — did not provide more than half of their own support.
Qualifying Relative: The Tests
A "qualifying relative" (which can include adult children, parents, or even an unrelated person you support) must meet:
- Not a qualifying child of anyone.
- Income — earned under the IRS threshold (roughly $5,000 for 2026, adjusted annually).
- Support — you provided more than half of their total support for the year.
- Relationship or residency — either they're a close relative (who doesn't have to live with you), or they lived with you all year.
Common Questions, Answered
- "Can I claim my girlfriend/boyfriend?" — Yes, if they lived with you all year, earned under the threshold, and you paid over half their support. They can't be claimed elsewhere.
- "Can I claim my adult kid who lives at home?" — Only as a qualifying relative, and only if they earn under the income threshold and you support them over half. Once they have a real income, no.
- "Can I claim my parent in a nursing home?" — Usually yes as a qualifying relative, and they don't have to live with you.
Frequently Asked Questions
Can two people claim the same dependent?
No. A dependent can only be claimed once. If two people try (like divorced parents), the IRS tiebreaker rules decide — and the return that's second gets rejected.
Does a dependent have to be a citizen?
For the child tax credit, the child generally needs a Social Security number and to be a U.S. citizen, national, or resident alien. Other dependents (like a qualifying relative) may qualify with an ITIN.
Can I claim myself if my parents claim me?
No — if you can be claimed as a dependent (even if your parents don't actually claim you), you generally can't claim your own personal exemption or certain credits. It's based on eligibility, not whether they actually filed.
What proof should I keep?
Records of residency (shared address), support (receipts for what you paid), and the person's income. If the IRS questions a dependent, you'll want documentation.
