The correct answer is that individuals must be married as of December 31st of the tax year to qualify for filing jointly. This criterion is essential as it establishes the legal marital status required by the IRS for taxpayers wishing to file a joint return. If a couple is legally married on the last day of the tax year, they can elect to file their tax return as "Married Filing Jointly."

This situation allows both spouses to report their combined income and claim deductions and credits together, which can often result in a lower tax liability compared to filing separately. It is crucial to note that the definition of married encompasses those who are legally recognized as such under state law, allowing for a broader understanding of marital status beyond just being citizens.

While other options mention different requirements, they do not accurately reflect the primary eligibility criterion needed for joint filing. For instance, only one spouse needing a Social Security number is not a requirement; both need to have valid taxpayer identification numbers. Similarly, there is no stipulation regarding both spouses needing to be U.S. citizens or being under 65 years old, as these factors do not determine eligibility for filing jointly under IRS regulations.
