Which returns can be e-filed if completed timely?

The correct answer indicates that both options A and B are eligible for e-filing if completed timely.

For option A, e-filing is fully supported for taxpayers who possess Social Security Numbers (SSNs). The IRS allows individuals with SSNs to e-file their returns smoothly, which facilitates faster processing and helps ensure accuracy.

Regarding option B, even if a return includes an adopted child without an SSN, it can still be e-filed, provided certain criteria are met. The adoption process often has specific IRS rules, but generally, as long as the overall return is filed on time, e-filing remains an option. Taxpayers can use an Adoption Taxpayer Identification Number (ATIN) for adopted children who have not yet received an SSN, enabling them to e-file as well.

These details illustrate why both A and B qualify for e-filing, underscoring the importance of timely submission in maintaining eligibility for electronic filing options.
