Final answer:
James may qualify for the Head of Household filing status because he supports his grandmother who lives with him, provided certain IRS criteria are met.
Step-by-step explanation:
The filing status for James, who is single and supports his grandmother that lives with him, may be Head of Household if he meets certain IRS criteria. Being single typically indicates one would file as Single; however, if a taxpayer is supporting a qualifying person, such as a grandparent, they may qualify for the Head of Household status. To qualify, the grandparent must meet specific IRS tests, which include considering whether the grandparent qualifies as a dependent based on income limits, support provided, and citizenship or resident tests.
John's background story, although similar in that it involves family support, is not directly applicable to the question about James' filing status. James must assess his ability to claim his grandmother and his eligibility based on tax law to determine the correct filing status for his situation.
