Final answer:
The gross income test requires a qualifying relative’s income to be below a certain threshold amount.
Step-by-step explanation:
The gross income test requires that a qualifying relative's gross income for the year be less than the threshold amount. This threshold amount varies depending on the specific tax year and the relationship between the taxpayer and the qualifying relative.
For example, in 2021, if a taxpayer is claiming a dependent as a qualifying relative, the gross income of that dependent must be less than $4,300 for the year in order to meet the gross income test.
It's important to consult the current tax laws and guidelines to determine the specific threshold amount for a given tax year.
