Final Answer:
James' filing status would likely be "Head of Household."
Step-by-step explanation:
To qualify as "Head of Household" for tax filing purposes, James must meet certain criteria. Being unmarried or considered unmarried on the last day of the tax year, paying more than half the cost of maintaining a home, and having a qualifying person (in this case, his grandmother) living with him for more than half the year are essential conditions.
Given that James is single and supports his grandmother who lives with him, he may meet the criteria for the "Head of Household" filing status. This status generally offers more favorable tax rates and a higher standard deduction compared to the "Single" filing status.
It's advisable for James to review the specific IRS guidelines or consult with a tax professional to ensure accurate filing based on his individual circumstances.
