Final answer:
If Jeffrey is required to file a tax return and meets all the tests to be claimed as a dependent on his parents' tax return, he should still file his own tax return. Claiming someone as a dependent on a tax return is a decision made by the taxpayer who is eligible to claim the dependent. When filing his tax return, Jeffrey should indicate that he can be claimed as a dependent on someone else's return. The correct statement is Jeffrey should file his own tax return by herself.
Step-by-step explanation:
If Jeffrey is required to file a tax return and meets all the tests to be claimed as a dependent on his parents' tax return, he should still file his own tax return. Even if his parents did not claim him as a dependent, it is still his responsibility to file his own taxes if he meets the requirements for filing.
Claiming someone as a dependent on a tax return is a decision made by the taxpayer who is eligible to claim the dependent. It is not mandatory for the eligible taxpayer to claim the dependent. Therefore, Jeffrey should file his own tax return.
When filing his tax return, Jeffrey should indicate that he can be claimed as a dependent on someone else's return. However, this does not prevent him from filing his own return and reporting his own income and deductions.
