Tom’s mother, Christine, has been living with his family for 10 years. Christine is insistent that Tom doesn’t claim her as a dependent because she’s worried it may affect her Medicare/Medicaid benefits for nursing home subsidies if and when that time comes.
- The parent must be a citizen, a resident alien or national of the United States, or a citizen of Canada or Mexico.
- The parent can’t file a joint tax return with any other person. If Christine is married and filing jointly with her husband, Tom wouldn’t be able to take the deduction.
- The parent’s gross taxable income can’t exceed the I.R.S.’s personal exemption, which is set each year. It’s $3,800 for 2012. Social Security income, however, isn’t taxable unless someone receives more than $34,000 in total income.
- The child must provide more than half of the parent’s support during the calendar year. Let’s say your mother’s expenses for the year amount to $12,500 for food, lodging, clothing, medical and dental care, transportation and recreation — anything spent on her behalf. In our example, Christine will collect $6,000 in Social Security benefits this year, so Tom would have to spend more than that, at least $6,001, to claim her as a dependent.
