Does Daniela's father need to file a tax return based on his income?

When determining whether Daniela's father needs to file a tax return based on his income, it's essential to consider the thresholds for income that necessitate filing. The requirement to file a tax return typically depends on a taxpayer's gross income, filing status, and age.

In this case, if Daniela's father has income below the threshold set by the IRS for his particular situation, he would not be required to file a tax return. For instance, if his income solely consists of Social Security benefits, and those benefits do not exceed the filing requirement, he may not need to file at all.

Furthermore, if he has no taxable income from other sources or if any additional income does not raise his total income above the minimum threshold, then he would not need to file a return. This means that option B accurately reflects that under certain circumstances, particularly involving low income and the nature of that income, a tax return is not necessary.

In contrast, if he were receiving income from sources other than Social Security, had a mix of various income forms, or was classified as a non-resident based on his tax situation, those factors could change whether he needs to file.
