Which test prohibits an individual from providing over half of their own support for the year to be considered a Qualifying Child?

The correct answer is the QC Support test, which is a critical criterion used to determine whether a child qualifies as a "Qualifying Child" for tax purposes. The Support test specifically states that to be considered a Qualifying Child, the individual must not have provided more than half of their own support during the year in question.

This concept is significant because it helps to establish dependency and eligibility for various tax benefits, such as the Child Tax Credit or the Earned Income Tax Credit.

Understanding the context of the other tests helps clarify the focus of the Support test. The Age test examines the age of the child to ensure they meet the required age criteria. The Residency test evaluates whether the child lived with the taxpayer for more than half of the year, which is also essential but does not pertain to the individual's support contributions. The Relationship test ensures that the child falls within a specified relationship to the taxpayer, which, while important for qualifying, doesn't address the aspect of financial support specifically.

Thus, the QC Support test effectively highlights the requirement regarding financial support, making it the correct choice.
