Which relationship qualifies as a way a Qualifying Child can be related to a taxpayer?

A Qualifying Child is defined by several criteria, including the relationship they have with the taxpayer. The relationship must be direct and can include a biological link. A son or daughter meets this criterion perfectly, as it is a direct familial relationship recognized under tax rules. This relationship is significant because qualifying children are eligible for various tax benefits, such as the Child Tax Credit, which can substantially affect a taxpayer's liability.

On the other hand, cousins do not qualify as immediate family members under this definition, nor do friends or step-parents. While a step-child could qualify, a step-parent does not fit the definition of a qualifying child since they are not in the same lineage as the taxpayer. Understanding these specific relationships is crucial for taxpayers who seek to maximize their deductions and credits related to dependents.
