What Is a Dependent?
A dependent is someone you support who may give you tax benefits when you claim them on your tax return. Often this is a child, but it can also be certain relatives in specific situations.
⚠️Important: Dependent rules can be detailed and change over time. This page gives a plain-language overview, not every technical rule or exception.
💰Why dependents matter for your taxes
Claiming a dependent can affect your taxes in several ways:
Child Tax Credit
May qualify you for valuable tax credits
EITC
May qualify you for Earned Income Tax Credit
Filing Status
May affect your filing status (e.g., head of household)
Other Credits
Education credits, dependent care credits, and more
📌 Important: Because the benefits can be significant, the IRS has detailed rules about who you can claim and when.
🔀Two broad categories
In general, potential dependents fall into two main groups:
Qualifying Children
Usually your kids, but specific tests apply
Qualifying Relatives
Can include parents, siblings, or others you support
🔍 Note: Each category has its own set of tests, including relationship, residency, support, and other conditions.
👧Qualifying child: the basic idea
A qualifying child is usually your son, daughter, stepchild, foster child, sibling, or a descendant of one of these, who meets several tests. In simplified form, the tests look at:
Relationship
The child must be related to you in specific ways defined by the IRS
Age
Usually under a certain age limit, or a full-time student under a slightly higher age limit, or disabled
Residency
The child must generally live with you for more than half the year (with some exceptions)
Support
The child must not have provided more than half of their own support
Joint Return
The child usually cannot file a joint return with a spouse, except in limited situations
⚠️ Details matter: Each of these tests has technical details and exceptions; this is just the big-picture idea.
👴Qualifying relative: the basic idea
A qualifying relative may be a broader range of people, including certain relatives and sometimes nonrelatives who live with you all year. In simplified form, the tests look at:
Relationship or Residency
The person is closely related to you or lives with you all year as a member of your household
Income
The person's income must be below a certain limit set by law for the year
Support
You must provide more than half of their total support for the year
Not a Qualifying Child
The person cannot already be someone else's qualifying child
📌 Common use: These rules often apply to elderly parents or other relatives you help support.
