Can you claim a child who pays half their own support?

What the test actually says

The qualifying child support test is one sentence: the child cannot have provided more than half of their own support for the year. Note what it does not say. It does not require that you provide more than half; it only requires that the child not provide more than half. If the child provided $6,000 of a $10,000 total, the child is out. If the child provided $4,000 and the other $6,000 came from you, a grandparent and a state program, the test is met even though you paid under half. The test is different from the qualifying relative support test, where you must provide more than half, though the same definition of what counts as support applies to both.

What counts as the child's own support

The child's own funds are support only when they are actually spent on support. Savings that stay in the bank are not. You also cannot count any support the child paid for with their own wages, even if you paid the wages. A scholarship received by a child who is a student is not taken into account at all. Social security benefits a child uses toward their own support are counted as provided by the child. Tax-exempt income, savings and borrowed amounts spent on the person count too: a student loan the child is responsible for and uses on tuition counts as the child's support.

The home matters. If the child owns the home in which they live, its fair rental value counts as support provided by the child. Property is measured at fair market value. In the publication's example, a 17-year-old buys a $4,500 car with personal funds while you provide $4,000 of the rest; the car counts as the child's support, the child provided more than half of $8,500 and is not your qualifying child, and you did not provide more than half, so you cannot claim the child as a relative either.

What counts as total support

Total support covers food, lodging, clothing, education, medical and dental care, recreation, transportation and similar necessities. Lodging is counted at fair rental value, including a reasonable allowance for furniture and utilities, rather than your actual costs. Household expenses such as food are divided among the people in the home. Medical insurance premiums you pay count; insurance benefits do not. Child care payments count even if you claim a credit for them. The cost of a capital item counts only if it benefits the child alone: a television in the child's bedroom does, a lawn mower for the household does not, and a car you own and share does not, though the costs of operating it for the child do.

Some items are excluded: federal, state and local income taxes and social security and Medicare taxes paid from the person's own income, life insurance premiums, funeral expenses, scholarships received by your child who is a student, and survivors' and dependents' educational assistance payments used for the child. GI Bill amounts for tuition and allowances are included.

Foster children and government payments

Payments you receive for a foster child from a child placement agency are treated as support provided by the agency, and payments from a state or county as support provided by the state or county. So a foster child supported by $3,000 from you and $4,000 from the state did not provide more than half of their own support. Under proposed Treasury regulations, TANF or similar payments you receive and use for another person are treated as support you provided.

The worksheet, in order

Worksheet 2 starts with the child's own funds and what was spent on support (line 2), adds the household expenses divided by the number of people (lines 6 to 13), adds clothing, education, medical, travel and other items for the person (lines 14 to 18), and totals the cost of the person's support on line 19. Line 20 is half of that. Line 21 is what the person provided, plus the home's fair rental value if the person owned it. If line 21 is more than line 20 the answer is yes, the person provided more than half, and the person is neither your qualifying child nor your qualifying relative. Lines 23 to 26 then measure what you provided against half, to test qualifying relative status. The calculator above takes lines 19, 21 and 23 as inputs.

Worked example

Your 19-year-old student's total support for the year is $14,000. The child spent $5,000 of earnings and savings on their own support, and a state program paid $1,000. You provided the remaining $8,000. Half of $14,000 is $7,000. The child's $5,000 is less, so the child did not provide more than half and the support test for a qualifying child is met. Now raise the child's own spending to $7,500: it exceeds $7,000, the child provided more than half, and the child is not your qualifying child whatever your other facts. Enter your own totals above.

Other tests still apply

Passing support does not make anyone a qualifying child. The child must also meet the relationship, age, residency and joint return tests, and a married child who files a joint return generally fails unless the return is only to claim a refund of withheld tax. If the support test is the only one failing and the child is a relative, your remaining route is to qualify them as a relative, which requires you to provide more than half. For a person supported by several relatives see the multiple support agreement page.
