What are the three factors that determine the filing requirement for nondependents?

The correct answer identifies age, gross income, and marital status as the three factors determining the filing requirement for nondependents.

Age is significant because the tax filing requirements vary based on whether an individual is under 65 or 65 and older. For instance, different income thresholds apply based on age brackets, influencing whether a nondependent is required to file.

Gross income is the total income received in the form of money, goods, property, and services that is not exempt from tax. The IRS establishes specific income thresholds that nondependents must meet to determine if a tax return is required. If their gross income surpasses these thresholds established for their age and filing status, they must file.

Marital status also plays a crucial role as it can affect the income thresholds and the overall filing requirements. For example, a married individual may have different filing needs compared to a single person, which can impact whether they need to file taxes based on their total income.

These three factors combined provide a clear framework that helps determine whether nondependents need to file a tax return based on their individual circumstances.
