A qualifying relative is an individual a taxpayer may claim as a dependent under section 152 of the Internal Revenue Code by the route that carries no age test. Four conditions have to hold at once: the individual is not a qualifying child of the taxpayer or of any other taxpayer, bears one of the family relationships the statute lists or lives in the taxpayer’s household for the whole taxable year, has gross income for the calendar year below the exemption amount defined in section 151(d), and receives over one-half of their support from the taxpayer (26 U.S.C. 152(d)).
Publication 501 works through each of those four at full depth (IRS, Publication 501 (2025)), and section 152(b) adds three more tests before anyone may actually be claimed, on the dependent taxpayer, the joint return and citizenship or residence (26 U.S.C. 152(b)). Both routes sit side by side in dependents.
There Is No Age Test at All
The conditions in section 152(d)(1) do not include one (26 U.S.C. 152(d)(1)).
Age is what closes the other route, so this is the sharpest separator between the two. A 30-year-old child living with the taxpayer, and not permanently and totally disabled, fails the qualifying child age test and can still be a qualifying relative if the gross income and support tests are met (IRS, Publication 501 (2025), 26 U.S.C. 152(c)(3)(B)).
The Relationship Test Has Two Branches
The first branch is a closed list in section 152(d)(2), running from a child or a descendant of one through siblings, ancestors, stepparents, aunts and uncles, nieces and nephews, and the in-law relations (26 U.S.C. 152(d)(2)). Nobody on it has to live with the taxpayer.
Everyone else takes the second branch, which asks for the same principal place of abode as the taxpayer and membership of that household for the taxpayer’s whole taxable year, and never reaches anyone who was the taxpayer’s spouse at any time during the year (26 U.S.C. 152(d)(2)(H)). That branch also fails outright if at any time during the year the relationship between the two violates local law (26 U.S.C. 152(f)(3)).
The whole taxable year is the difference that catches people, because the qualifying child residency condition is satisfied by the same principal place of abode for more than one-half of the taxable year (26 U.S.C. 152(c)(1)(B)). A cousin is not on the list, which puts a cousin on this branch and means a cousin must live with the taxpayer all year (IRS, Publication 501 (2025)).
The Support Test Runs the Opposite Way
For a qualifying relative, the taxpayer must provide over one-half of the individual’s support for the calendar year (26 U.S.C. 152(d)(1)(C)). For a qualifying child, the question is the individual’s own contribution instead, and the child must not have provided over one-half of their own support (26 U.S.C. 152(c)(1)(D)).
The two questions land differently on the same facts. Where a third party pays most of the cost, the child condition still holds while this one fails for everyone who did not personally clear the halfway mark. Where no one person reached half but two or more people who could otherwise claim the individual together paid over half, a multiple support agreement can move the claim to one of them (26 U.S.C. 152(d)(3)), on the mechanics carried in dependents.
What a Qualifying Relative Is Confused With
The qualifying child is the confusion that matters, and the two routes are mutually exclusive by statute rather than by preference. Section 152(d)(1)(D) shuts this route to anyone who is a qualifying child of the taxpayer or of any other taxpayer for a taxable year beginning in that calendar year (26 U.S.C. 152(d)(1)(D)), so the child tests run first.
The name misleads as well, because a listed relative never has to share a home and an unrelated person can qualify by living in the household all year.
A qualifying relative can never feed the child tax credit, and the credit it can feed is the credit for other dependents, subject to that credit’s own narrower residency condition (26 U.S.C. 24(h)(4)).
Common Questions About Qualifying Relatives
Anyone who meets all four conditions and is not already someone’s qualifying child (IRS, Publication 501 (2025)): an adult child past the age limits, a parent, an aunt or uncle, an in-law, or an unrelated household member.
Only on one branch. A relation on the section 152(d)(2) list qualifies without living with the taxpayer at all, and everyone else has to live in the household for the entire taxable year (26 U.S.C. 152(d)(2)).
Gross income for the calendar year must be under the exemption amount defined in section 151(d) (26 U.S.C. 152(d)(1)(B)), meaning all income in money, property and services that is not exempt from tax (IRS, Publication 501 (2025)).
The amount is indexed. For taxable years beginning in 2025 it is $5,200 (IRS, Rev. Proc. 2024-40).
For taxable years beginning in 2026 it is $5,300 (IRS, Rev. Proc. 2025-32). Why a live exemption amount survives a personal exemption worth zero is in personal exemption.
The child route tests age and asks only for more than half a year of shared residence. This route has no age test, splits residence into the two branches above, and reverses the support question (26 U.S.C. 152).
