If you support a child, parent or another family member, you may be able to claim them as a dependent on your tax return. Doing so can lower your tax bill through credits, deductions and other tax benefits — but only if the person meets specific IRS rules.

This guide explains who counts as a dependent, how the IRS defines qualifying children and qualifying relatives, what tax benefits you may unlock and how to avoid common mistakes. Everything here reflects current IRS guidance and is written to give you clear, confident answers.

The Internal Revenue Service sets strict requirements for claiming dependents, and meeting every test matters.

Quick Answer: Who Can You Claim as a Dependent?

You can generally claim someone as a dependent if:

• They are a qualifying child or a qualifying relative
• You provide more than half of their financial support
• They meet IRS tests for relationship, residency, income and support
• They are a U.S. citizen, resident alien or qualifying resident of Canada or Mexico

If even one test fails, the IRS may deny the claim.

Claiming Dependents At a Glance

Why Claiming Dependents Matters

Claiming a dependent can unlock valuable tax benefits, including:

• The Child Tax Credit
• The Credit for Other Dependents
• The Child and Dependent Care Credit
• Head of household filing status
• Education credits in some cases

According to the IRS, credits tied to dependents can reduce your tax bill dollar for dollar, making eligibility especially important.

What Is a Qualifying Child?

A qualifying child must meet all of the following IRS tests.

Relationship Test

The child must be your:

• Son or daughter
• Stepchild
• Foster child placed by an authorized agency
• Brother or sister
• Grandchild, niece or nephew

Age Test

At the end of the tax year, the child must be:

• Under age 19
• Under age 24 if a full-time student
• Any age if permanently and totally disabled

Residency Test

The child must live with you for more than half the year. Temporary absences for school, medical care or military service usually still count as living with you.

Support Test

The child cannot provide more than half of their own financial support during the year. Support includes housing, food, education, clothing and medical care.

Joint Return Test

The child can’t file a joint tax return with a spouse unless it’s only to claim a refund.

What Is a Qualifying Relative?

A qualifying relative does not need to be related to you in the traditional sense, but they must meet IRS rules.

Relationship Or Household Member Test

A qualifying relative must either:

• Be related to you (parent, sibling, aunt, uncle, in-law)
• Live with you all year as a member of your household

Gross Income Test

The dependent’s gross income must be below the IRS limit for the year.

The IRS updates this threshold annually.

Support Test

You must provide more than half of the person’s total support for the year. Support includes rent, utilities, food, medical expenses and transportation.

Can You Claim a Parent as a Dependent?

Yes, many taxpayers claim parents as dependents. Common situations include:

• Paying most of a parent’s living expenses
• Covering medical or long-term care costs
• Supporting a parent who lives with you or elsewhere

The IRS allows parents to qualify even if they don’t live with you.

What Tax Credits Do Dependents Unlock?

Claiming a dependent can qualify you for several credits.

Child Tax Credit

• Available for qualifying children under age 17
• Partially refundable in some cases
• Income limits apply

Credit for Other Dependents

• For dependents who do not qualify for the Child Tax Credit
• Common for older children or elderly parents

Child and Dependent Care Credit

• Helps offset daycare or caregiving costs
• Applies to children under 13 or disabled dependents

Common Mistakes When Claiming Dependents

• Claiming the same dependent as another taxpayer
• Missing the residency requirement
• Overlooking income limits
• Failing to document support
• Claiming dependents who file joint returns improperly

The IRS frequently flags dependent-related errors during audits.

What Happens If Two People Claim the Same Dependent?

If two taxpayers claim the same dependent, the IRS applies tie-breaker rules based on:

• Relationship
• Residency
• Adjusted gross income

Only one taxpayer can claim the dependent.

What Documents Should You Keep?

To support your claim, keep records like:

• Birth certificates or adoption papers
• School or medical records
• Proof of residency
• Financial support documentation

The IRS recommends keeping tax records for at least three years.

Final Take to GO

Claiming dependents on taxes can significantly reduce your tax bill, but the rules are strict. To qualify, a dependent must meet IRS tests for relationship, residency, income and support.

Understanding the difference between a qualifying child and a qualifying relative — and keeping good records — can help you claim the tax benefits you’re entitled to while avoiding costly mistakes.
