If Max is 20 years old, lives with his aunt all year, and she pays more than half of his living expenses, can she claim him as a dependent on her federal tax return? The answer is yes, potentially. However, paying for most of his expenses and providing a place to live are not the only requirements.
The Internal Revenue Service (IRS) has specific rules for determining whether someone qualifies as a dependent. These rules look at the person’s income, family relationship, living arrangements, financial support, and eligibility to be claimed by another taxpayer.
In Max’s situation, his aunt may be able to claim him as a dependent if he meets the remaining IRS requirements. Let’s walk through the rules in plain English so you can understand exactly what needs to happen.
Quick Answer: What Else Must Happen for Max to Qualify?
For the 2025 tax year, Max generally must meet the following requirements to qualify as his aunt’s dependent under the qualifying-relative rules:
- His gross income must be less than $5,200 for the year.
- He must not be the qualifying child of his aunt or any other taxpayer.
- He must meet the IRS relationship or household requirement.
- His aunt must provide more than half of his total support for the year.
- He must meet the applicable citizenship or residency requirements.
- He generally must not file a joint tax return with a spouse, except when filing jointly only to claim a refund of withheld or estimated tax payments.
- His aunt must meet the applicable taxpayer eligibility requirements, including not being someone else’s dependent.
The scenario already tells us that Max lives with his aunt year-round and that she pays more than 50% of his living expenses. Those facts help establish the household and financial support requirements. However, his income and eligibility under the qualifying-child rules still need to be checked.
For the official rules, see the IRS’s Publication 501: Dependents, Standard Deduction, and Filing Information.
1. Understand the Two Ways Someone Can Qualify as a Dependent
Before deciding whether Max qualifies, it helps to understand that the IRS recognizes two main categories of dependents.
Qualifying Child
A person may qualify as a qualifying child if they meet specific requirements involving age, relationship, residency, financial support, and other eligibility rules.
For example, a parent may generally claim an unmarried 20-year-old child who is a full-time student under age 24 if the other qualifying-child requirements are satisfied.
Aunt-and-nephew relationships can also meet the relationship requirement for qualifying-child purposes. However, Max must satisfy all the applicable rules, not just the age and relationship tests.
Qualifying Relative
A qualifying relative is someone who meets a different set of IRS requirements. Despite the name, this category does not always require the person to be a close family member.
A qualifying relative must generally:
- Not be the qualifying child of any taxpayer.
- Meet the relationship or household test.
- Have gross income below the applicable annual limit.
- Receive more than half of their total support from the taxpayer claiming them.
There is no maximum age for a qualifying relative.
In Max’s case, his aunt may be able to claim him under the qualifying-relative rules if he meets every applicable requirement.
Important: Max cannot be treated as a qualifying relative if he qualifies as the qualifying child of another taxpayer. His age alone does not determine which category applies.
2. Max’s Gross Income Must Be Below the IRS Limit
One of the most important requirements is the gross income test.
For the 2025 tax year, a qualifying relative generally must have gross income of less than $5,200.
This means that if Max’s gross income is $5,199, he may pass this test. If his gross income is exactly $5,200 or more, he generally fails the qualifying-relative gross income test.
The threshold applies to the 2025 tax year, so taxpayers checking eligibility for another year should verify the applicable IRS limit.
What Counts as Gross Income?
Gross income generally includes taxable income received in the form of money, property, or services. Depending on the circumstances, it may include:
- Wages and salaries from a job.
- Taxable interest.
- Taxable business income.
- Rental income.
- Certain taxable investment income.
Not every payment is treated as gross income for this test. Tax-exempt income and certain other items may be treated differently under IRS rules.
For example, if Max works part-time at a grocery store and earns $3,500 in wages during 2025, he may pass the gross income test, assuming he has no other income that pushes him over the limit.
However, if he earns $6,000 in taxable wages, he generally fails the qualifying-relative gross income test for that year, even if his aunt pays most of his living expenses.
Passing the income test alone does not automatically make Max a dependent. All the other requirements must also be satisfied.

3. Max Must Not Be the Qualifying Child of Another Taxpayer
This is another critical requirement.
The IRS does not allow someone to qualify as a qualifying relative if that person is the qualifying child of another taxpayer.
Consider a situation in which Max is 20 years old, attends college full-time, and meets all the qualifying-child requirements for his mother. Even if Max lives with his aunt throughout the year and his aunt pays most of his expenses, his aunt generally cannot claim him as a qualifying relative.
Why? Because he may already qualify as someone else’s qualifying child.
The IRS considers several factors when determining whether someone qualifies as a qualifying child, including:
- Relationship to the taxpayer.
- Age.
- Residency.
- Whether the person provided more than half of their own support.
- Other applicable tax-filing requirements.
For example, a 20-year-old full-time student may satisfy the age requirement for qualifying-child status if the other requirements are met. A 20-year-old who is not a full-time student generally will not meet the usual age test unless an applicable exception applies.
This distinction matters because Max’s aunt cannot rely only on his age or her financial contributions to determine whether she can claim him.
If Max does not qualify as the qualifying child of any taxpayer, his aunt can move on to the qualifying-relative tests.
4. Max Must Meet the Relationship or Household Test
The IRS also requires a qualifying relative to satisfy a relationship or household test.
Generally, the person must either be related to the taxpayer in a qualifying way or live with the taxpayer as a member of the household for the entire year.
An aunt and nephew have a qualifying family relationship for these purposes. A nephew is the son of a taxpayer’s sibling.
Therefore, Max does not need to rely solely on the household rule to establish the required relationship with his aunt.
The fact that he lives with her year-round also supports the household aspect of the situation.
However, the IRS rules still require the other tests to be satisfied.
For example, if Max lived with a family friend rather than his aunt, the household test could become especially important. An unrelated person generally must live with the taxpayer as a member of the household for the entire year to qualify under the qualifying-relative household rule.
Temporary absences may be treated differently in certain circumstances, so the details of a person’s living arrangements can matter.
5. His Aunt Must Pay More Than Half of His Total Support
The question states that Max’s aunt pays for more than 50% of his living expenses. This is an important fact because it suggests that she may meet the support test.
However, the IRS support test is based on more than half of Max’s total support, not simply more than half of a particular category of expenses.
Total support can include:
- Housing and lodging.
- Food.
- Clothing.
- Medical and dental care.
- Education.
- Transportation.
- Recreation and other necessary living expenses.
The aunt’s contributions must be compared with the total support Max receives from all sources, including money he actually spends on his own support.
Example: How the Support Test Works
Suppose Max’s total support for 2025 is $12,000.
His aunt pays $7,000, Max pays $3,000 from his earnings, and another family member contributes $2,000.
The calculation looks like this:
| Support source | Amount |
|---|---|
| Aunt | $7,000 |
| Max | $3,000 |
| Other family member | $2,000 |
| Total support | $12,000 |
His aunt provides approximately 58.3% of his total support.
Since she provides more than half, she meets the support test, assuming the figures accurately reflect the total support provided.
Now imagine his aunt pays only $5,000 of the same $12,000 total. She would provide less than half and would generally fail the support test for claiming Max as a qualifying relative.
The IRS provides guidance and a worksheet in Publication 501 to help taxpayers calculate total support.
Remember: Money Max earns is not automatically counted as support he provided. The relevant question is how much of his own money he actually spent on his support.
6. Max Must Meet the Citizenship or Residency Requirement
The IRS also has citizenship and residency rules for dependents.
Generally, a dependent must be a U.S. citizen, U.S. national, U.S. resident alien, or a resident of Canada or Mexico, subject to applicable exceptions.
Certain adopted children may qualify under special rules.
This requirement is particularly important when family members live in different countries or when someone has recently moved to the United States.
For instance, if Max is a U.S. citizen living with his aunt in the United States, this requirement would generally be satisfied.
If he has a different immigration or residency status, his aunt should review the applicable IRS rules before claiming him.
7. Check the Joint Return and Taxpayer Eligibility Rules
There are a couple of additional requirements worth checking before filing.
Joint Tax Return Rule
A person generally cannot be claimed as a dependent if they file a joint return with their spouse.
There is an exception when the joint return is filed only to claim a refund of income tax withheld or estimated tax paid, provided the other applicable conditions are satisfied.
If Max is unmarried and does not file a joint return, this particular restriction would generally not be an issue.
His Aunt’s Own Tax Status
The aunt must also satisfy the applicable rules for claiming a dependent.
For example, a taxpayer who can be claimed as someone else’s dependent generally cannot claim dependents of their own.
This means that even if Max meets the individual requirements, his aunt must also be eligible to claim him.
Tax situations can become more complicated when multiple family members provide financial support or when another taxpayer is considering claiming the same person.
When that happens, reviewing the complete facts before filing is the safest approach.
8. A Practical Checklist for Max’s Aunt
Before claiming Max on her tax return, his aunt can use the following checklist.
- Confirm which tax year she is filing for.
- Determine whether Max qualifies as the qualifying child of any taxpayer.
- Check whether Max’s gross income is below the qualifying-relative limit for that tax year.
- Confirm that he meets the relationship or household requirement.
- Calculate his total support and verify that she provided more than half.
- Verify the applicable citizenship or residency requirement.
- Check whether Max filed a joint return with a spouse.
- Confirm that she meets the requirements to claim a dependent herself.
Keep useful records of support payments, housing expenses, income information, and other relevant documentation. These records can help explain the decision if the IRS asks questions later.

FAQs
1. Can an aunt claim her 20-year-old nephew as a dependent?
Yes, potentially. An aunt may be able to claim her 20-year-old nephew as a dependent if he qualifies as either a qualifying child or a qualifying relative and all applicable IRS requirements are met. Under the qualifying-relative rules, his income, relationship, support, and eligibility under the qualifying-child rules must be considered.
2. How much income can Max earn and still be claimed as a qualifying relative?
For the 2025 tax year, Max’s gross income generally must be less than $5,200 to satisfy the qualifying-relative gross income test. This is a gross income threshold, not a limit on the amount of money he can receive from every possible source. The tax treatment of different types of income can vary.
3. Does Max have to be a full-time student for his aunt to claim him?
Not necessarily. A qualifying relative does not have to be a full-time student and has no maximum age limit. However, if Max is a full-time student under age 24, he might qualify as someone else’s qualifying child if the other requirements are met. That possibility must be considered before his aunt claims him as a qualifying relative.
4. Is paying more than half of Max’s expenses enough to claim him?
No. Paying more than half of his total support satisfies only one part of the qualifying-relative rules. His aunt must also satisfy the applicable taxpayer requirements, and Max must meet the income, relationship or household, and qualifying-child tests, along with other applicable requirements.
5. Can Max file his own tax return if his aunt claims him as a dependent?
Yes. Being claimed as a dependent does not automatically prevent Max from filing his own federal income tax return. Depending on his income, withholding, and other circumstances, he may need to file or may choose to file to claim a refund. He should follow the IRS rules for his own filing obligations and indicate his dependent status accurately when required.
Conclusion
So, can Max’s aunt claim him as a dependent if he is 20 years old, lives with her all year, and she pays more than half of his living expenses?
Possibly, yes, if he meets all the applicable IRS requirements.
For the qualifying-relative route, two particularly important questions remain: Is Max’s gross income below the applicable annual limit, and is he the qualifying child of another taxpayer?
For the 2025 tax year, the gross income limit is less than $5,200. His aunt must also satisfy the other qualifying-relative requirements, including the support test and relationship or household test.
Before filing, review the official IRS guidance and verify the rules for the specific tax year. When a student, another family member, or multiple taxpayers may be eligible to claim Max, checking the complete facts can help prevent an incorrect dependent claim.
