What Are the Five Tests for a Qualifying Relative?

The five tests for a qualifying relative are the not-a-qualifying-child test, the relationship or member-of-household test, the gross income test, the support test, and the joint return test. The IRS technically groups four of these as qualifying-relative rules and treats the joint return rule as a general dependent requirement, but in practice all five must be cleared before you can claim the person on your return. For the 2026 tax year, the person’s gross income must stay below $5,300, and you must provide more than half of their total support.¹ Missing any one test disqualifies the claim entirely.

Test 1: Not a Qualifying Child

The person cannot be your qualifying child or the qualifying child of any other taxpayer for the same tax year.¹ This test exists to keep the same person from being claimed under both categories.

A qualifying child must satisfy their own five tests: relationship, age, residency, support, and joint return. The age test caps a qualifying child at under 19, or under 24 if a full-time student, or any age if permanently and totally disabled.² If the person fails one of those, they can potentially be your qualifying relative instead. Your 30-year-old son who lives with you is too old to be a qualifying child, but he may qualify as a qualifying relative if the remaining tests are met.¹

Qualifying relatives have no age limit. A 75-year-old parent and a 40-year-old sibling are both eligible on age grounds.

Test 2: Relationship or Member of Household

The person must either be related to you in a way the tax code recognizes, or must have lived with you as a member of your household for the entire tax year. You only need one of the two paths.³

Relatives Who Qualify Without Living With You

These family members meet the relationship path no matter where they live:

Children, stepchildren, foster children, and their descendants such as grandchildren and great-grandchildren
Parents, grandparents, and other direct ancestors
Siblings, half-siblings, and stepsiblings
Aunts, uncles, nieces, and nephews
In-laws: father-in-law, mother-in-law, brother-in-law, sister-in-law, son-in-law, and daughter-in-law

A mother who lives in another state can be your qualifying relative without setting foot in your home. Cousins are not on the IRS list, so a cousin fails the relationship path and can only qualify under the household path.³ A legally adopted child, or one lawfully placed with you for adoption, is treated the same as a biological child.⁴

Non-Relatives Who Live With You All Year

A friend, domestic partner, cousin, or anyone else not on the relationship list can still pass this test by living with you as a member of your household for the entire tax year.² Temporary absences for school, medical care, military service, or vacation don’t break the year. A person born or who died during the year is treated as having lived with you all year. If the living arrangement violates local law, the person cannot qualify through this path.³

Test 3: Gross Income Below the Annual Limit

The person’s gross income for the year must be less than the exemption amount, which is $5,300 for the 2026 tax year.⁴ The threshold was $5,200 for 2025 and adjusts annually for inflation.¹

Gross income means all income that isn’t tax-exempt. It includes wages, salaries, tips, taxable interest, ordinary dividends, capital gains, pensions, unemployment compensation, and the taxable portion of Social Security benefits. Tax-exempt income, such as the nontaxable portion of Social Security or interest from tax-free municipal bonds, does not count toward the threshold.¹ If you support an elderly parent whose Social Security is only partly taxable, only that taxable portion counts here.

Test 4: You Provided More Than Half Their Support

You must provide more than half of the person’s total support for the calendar year.¹ This is where most qualifying-relative claims break down, because the calculation counts more than what you personally spent.

Total support includes food, clothing, shelter (valued at fair rental value rather than what you actually pay in rent or mortgage), education, medical and dental care, recreation, and transportation. Government benefits the person receives, including welfare, food assistance, state-provided housing, and Social Security payments they spend on themselves, all count in the total support figure.⁵

Add up every dollar spent on the person’s support from every source, including what they spend on themselves, then compare your share to that total. If your mother receives $12,000 in Social Security and spends $10,000 of it on her own living expenses, that $10,000 goes into the total. You would need to provide more than $10,000 yourself before other sources are even considered. Income the person saves rather than spends on support is not counted in the total.⁵

Note the difference from the gross income test: the income test looks only at taxable income, while the support test counts all income, taxable and nontaxable, that is actually used for support.

Multiple Support Agreements

When several people together support one person and no single contributor pays more than half, a multiple support agreement lets one of them claim the dependent. All five conditions must be met:⁶

The contributors together paid more than half of the person’s total support.
The taxpayer claiming the dependent personally paid more than 10% of the total support.
No single person paid more than half.
The person passes all the other qualifying-relative tests.
Every other eligible contributor who paid more than 10% signs a written statement agreeing not to claim the dependent that year.

Form 2120 is not filed with your return, but you should keep the signed waivers with your records. Siblings splitting the cost of a parent’s care commonly rotate who takes the claim each year using this arrangement.

Test 5: The Joint Return Test

You generally cannot claim someone as a dependent if they file a joint return with their spouse.¹ Supporting a married daughter and her spouse financially doesn’t override this rule if the couple files jointly.

One narrow exception applies. You can still claim them if the only reason they filed jointly was to claim a refund of withheld income tax or estimated tax paid, and neither spouse would owe any tax if they had filed separately.

Citizenship and Residency Boundary

All dependents, qualifying relatives included, must be a U.S. citizen, U.S. national, or U.S. resident alien, or a resident of Canada or Mexico.⁷ If you’re supporting a family member who lives abroad outside those countries and is not a U.S. citizen or resident, you cannot claim them regardless of how much support you provide.⁸

What You Get for Claiming a Qualifying Relative

The personal exemption has been zero since the Tax Cuts and Jobs Act took effect and remains zero through at least the 2025 tax year.¹ The main benefit today is the Credit for Other Dependents, a $500 nonrefundable credit for each qualifying relative you claim. Because it’s nonrefundable, it can reduce your tax to zero but won’t generate a refund on its own. The credit begins to phase out when adjusted gross income exceeds $200,000, or $400,000 for married couples filing jointly.⁹

Claiming a qualifying relative can unlock other benefits as well. You may deduct medical expenses you pay on the dependent’s behalf, and the dependent care credit may apply if the person is disabled. Supporting a qualifying relative who is your parent can also let you file as head of household, which brings a larger standard deduction ($24,150 for 2026 versus $16,100 for single filers) and more favorable brackets.¹⁰ For head of household purposes, a parent does not have to live with you, but you must pay more than half the cost of keeping up their home.
