Credit for Other Dependents
The Credit for Other Dependents (ODC) is the CTC's quieter sibling: $500 per eligible dependent, claimed on the same Schedule 8812, for dependents who do not qualify for the Child Tax Credit. The most common cases are a 17-year-old child, a full-time student aged 19 to 23 who is a qualifying relative rather than a qualifying child for CTC purposes, and a dependent parent. Unlike the CTC, the ODC is entirely nonrefundable — it can reduce your tax bill to zero, but it never produces a refund.
- ODC: $500 per eligible dependent, nonrefundable, claimed on Schedule 8812.
- Typical cases: a child aged 17 or older, a dependent parent, another qualifying relative.
- The same $200,000 / $400,000 phase-out thresholds apply, with the same $50-per-$1,000 reduction.
- A dependent can generate either the CTC or the ODC — never both for the same person in the same year.
Who counts as an other dependent
An other dependent is someone you claim as a dependent who is not a qualifying child for the CTC. Two groups matter most. The first is a qualifying child for dependency purposes who fails a CTC-only test — usually the age test (17 or older at year-end) or the SSN test (an ITIN instead of a valid-for-employment SSN). The second is a qualifying relative: someone whose gross income is below the annual exemption amount, whom you support with more than half of their support, and who is either related to you or lived with you all year. A dependent parent, a dependent adult child, and a dependent sibling can all fall here.
The identification rules for the ODC are separate from the CTC's SSN rule: a qualifying relative claimed for the ODC needs an SSN or ITIN issued by the return's due date including extensions. If the dependent has no qualifying number at all, neither credit is available for that person.
How it interacts with the CTC
Schedule 8812 handles the CTC and the ODC together, and the phase-out applies to the combined credit. Worked example, labelled as calculated: a single filer with one qualifying child and one dependent parent, MAGI of $200,000 exactly, keeps the full $2,200 CTC plus the $500 ODC — $2,700 in total nonrefundable credit value, before any ACTC split. At MAGI of $201,000, the $50-per-$1,000 reduction removes $50 from the combined credit, leaving $2,650. The ODC never becomes refundable: if this filer's tax bill were zero, the $500 would simply go unused, while the ACTC rules would still decide how much of the $2,200 CTC comes back as cash.
The common trap: assuming 17 means nothing
Parents often assume that the year a child turns 17, all child-related credits vanish. They do not: the CTC stops, but the ODC starts, provided the child is still a dependent and the other tests pass. The difference is real money — $500 against a tax bill — and it continues while the child remains a dependent, including through college years if the qualifying-relative tests are met. Check Schedule 8812 every year a child ages out of the CTC rather than dropping the schedule entirely.
