Final answer:
Diane, who lives in Texas and is filing Married Filing Separately, should report her total income of $100,000 from her job on her tax return.
Step-by-step explanation:
James and Diane are married and live in Texas, and Diane earns $100,000 a year at her job and is filing Married Filing Separately. On her tax return, Diane should report the total amount of income she earned from her job, which is $100,000. In Texas, since it is a community property state, spouses typically report half of their combined income when they file separately unless there are specific exceptions or an agreement otherwise.
However, the provided scenario does not mention other sources of income or special arrangements, so based solely on the information given, Diane should include $100,000 - which is her personal income from her job - on her return.
According to the information provided, Diane earns $100,000 a year at her job and she and James file taxes using the Married Filing Separately status. When filing separately, each spouse reports their own income on their individual tax returns. Therefore, Diane should include her entire income of $100,000 on her tax return.
