What generally disqualifies a taxpayer from claiming the Child Tax Credit?

The Child Tax Credit is subject to income limitations that determine eligibility based on the taxpayer's modified adjusted gross income (MAGI). When a taxpayer’s income exceeds the established phase-out thresholds, they may find their eligibility for the credit reduced or eliminated entirely. This phase-out begins at certain income levels and can significantly impact the amount of credit a taxpayer can claim. Hence, it is the high income exceeding these limits that generally disqualifies someone from claiming the Child Tax Credit.

Other choices do not directly affect the ability to claim the credit. For instance, having many dependents might increase eligibility rather than disqualify someone, being a single filer does not inherently disqualify a taxpayer from claiming the credit, and not owning property has no bearing on eligibility for the Child Tax Credit. All these aspects are important, but they do not serve as disqualifying factors the way exceeding the income threshold does.
