In order to pass the member of the household test, a dependent must what?

To pass the member of the household test, a dependent must completely reside with you all year. This requirement is crucial because the test is designed to establish a clear relationship and support structure between the taxpayer and the dependent. By residing with the taxpayer for the entire year, the dependent demonstrates the continuity of the household arrangement, which is a key factor in determining eligibility for claiming someone as a dependent.

This standard helps ensure that the dependent is truly part of the taxpayer's household and not just someone who may visit occasionally or live separately at times. Complete residency supports the notion of financial support and care throughout the year, which is fundamental to tax benefits associated with dependents. Other options suggest less consistent living arrangements, which do not meet the criteria for this test.
