In the first part of this series, we discussed the three basic U.S. filing statuses — Married Filing Jointly, Married Filing Separately, and Qualifying Surviving Spouse — and their detailed conditions. In the second part, we reviewed the rules for determining tax residency, focusing on the categories of resident alien, nonresident alien, and dual-status alien, as well as the possibility of the Head of Household status when filing a return. These tax statuses have a significant impact not only on tax liability but also on eligibility for tax benefits.

In today’s part, we will move forward and examine how the U.S. Internal Revenue Service (IRS) defines dependents and under what conditions a person qualifies as a Qualifying Child or Qualifying Relative in the tax system.

Defining Dependency Status: Qualifying Child and Qualifying Relative

The U.S. tax system places emphasis not only on tax residency but also on the determination of dependents, which can have a major impact on tax credits and deductions. U.S. tax law distinguishes between the concepts of Qualifying Child and Qualifying Relative, which determine whether a taxpayer may claim another individual for tax benefits such as the Child Tax Credit or deductions for dependents. The IRS has established detailed criteria for determining whether a person meets one of these categories.

Qualifying Child

To qualify as a Qualifying Child, the following criteria must be met:

  • Relationship test: The child must be the taxpayer’s son, daughter, stepchild, brother, sister, half-brother, half-sister, stepbrother, stepsister, or a descendant of any of these (e.g., a niece or nephew).
  • Age test: The child must be under 18 at the end of the tax year, or under 24 if a student. If the child is permanently disabled, there is no age limit.
  • Residency test: The child must live with the taxpayer for more than half of the year.
  • Support test: The child must not provide more than 50% of their own financial support.
  • Joint return test: The child cannot file a joint tax return with their spouse, unless it is filed solely to claim a tax refund.

If a child meets these conditions, they may qualify for the Child Tax Credit and other family-related tax benefits.

Example: P. and I. live with their healthy twin sons, J. and F., who are 20 years old and single at the end of 2024. P. and I. support both of them. J. is a full-time university student who earns $15,000 from a part-time job. F. is unemployed, not studying, and earned only $1,000 by house-sitting for friends during their vacation.

The key question: Can P. and I. list J. and/or F. as dependents?

For J., the answer is clearly yes. He is a full-time student under 24 and therefore meets the Qualifying Child criteria. For F., the answer is also yes, if his annual income does not exceed the allowed limit and P. and I. provided more than 50% of his financial support. In this case, however, he would not qualify as a Qualifying Child, but could be claimed as a Qualifying Relative.

Qualifying Relative

If a person does not meet the conditions for a Qualifying Child, they may still be considered a Qualifying Relative if the following requirements are met:

  • Relationship test: The dependent must be a close relative of the taxpayer (e.g., parent, grandparent, uncle, aunt, son-in-law, daughter-in-law, mother-in-law, father-in-law, stepchild, stepsibling, etc.) or must live with the taxpayer for the entire year.
  • Gross income test: The dependent’s income must not exceed a specified annual amount.
  • Support test: The taxpayer must provide at least 50% of the dependent’s total support.
  • Residency test: The dependent must be a U.S. citizen, resident, or under certain circumstances, a Canadian or Mexican resident.
Example: G.’s wife, M., passed away in 2022. In 2024, M.’s mother, J., lived with G., and G. provided virtually all of her financial support. J.’s only income was $5,000, which she donated entirely to her church. Is G. eligible to claim J. as a dependent on his tax return? The answer is yes. Even though his wife has passed away, G.’s mother-in-law still qualifies as a qualifying person and may be listed as a dependent.

Tax Credits and Deductions

If a person meets the criteria for either a Qualifying Child or a Qualifying Relative, the taxpayer may be eligible for several tax benefits, such as:

  • Child Tax Credit (CTC)
  • Earned Income Tax Credit (EITC)

Summary

We can see that defining the categories of Qualifying Child and Qualifying Relative is crucial for tax planning, as they affect the taxpayer’s eligibility for credits and deductions. Soon, we will move on to another interesting topic that will further deepen our understanding of the U.S. tax system.
