Final answer:
Taxpayers must file a tax return if their gross income is greater than $600, regardless of their filing status or income source.
Step-by-step explanation:
If your gross income is greater than $600, you would be required to file a tax return. This applies to all taxpayers, regardless of their filing status or income source. The IRS requires individuals to report their income and pay the appropriate taxes based on their earnings.
For example, if you are self-employed and earn more than $600, you would need to file a tax return. Similarly, if you have income from investments, rental properties, or any other source that exceeds $600, you must also file a tax return. Keep in mind that there may be additional requirements and deductions based on your specific circumstances, so it's important to consult a tax professional or refer to the IRS guidelines for more information.
