Final answer:
Nora should report one-half of the combined salaries of herself and Jim while they were married, one-half of the income from community property investments, and her income post-divorce on her separate return.The correct answer is option 3.
Step-by-step explanation:
The question pertains to how Nora should report her income on her separate return in 2015 after divorcing Jim. In a community property state, the law requires that income earned during the marriage is considered community property and should be split equally between the spouses.
Therefore, the correct answer is that Nora must report one-half of the combined salaries of Jim and herself for the period they were married, as well as one-half of the income from community property investments, and any income she earned after the divorce on her separate return.
This accounts for the fact that until their divorce, both Jim and Nora's earnings and income from investments were part of the community property.
