If youre supporting an elderly parent, you may qualify for some tax relief if you pass Uncle Sams tax test. Heres what you should know.

If youre supporting your elderly mother (or father), to get a tax deduction, youll need to claim her or him as a dependent on your tax return. For the 2007 tax year, claiming an additional personal exemption would reduce your taxable income by $3,400. But to get this tax break, youll need to pass two tests:

Income test: To qualify as a dependent, your parents 2007 income must be less than $3,400. Her income from Social Security does not count towards that total (disability payments dont count either). But if your parent receives more than $3,400 from other sources, such as pension benefits, interest and dividends from investments, or withdrawals from retirement savings plans, you cant claim him or her as a dependent.

Support test: In addition to the income test, you must provide more than half of your parents costs for housing, food, medical care, transportation and other necessities. Even if all your mother's or dad's income is from Social Security, you cant claim him or her as a dependent unless you pay more than half your parent's living expenses.

Note: Your parent doesnt have to live with you to qualify as a dependent, as long as she meets the income test and you provide more than half her financial support.

If your mother lives with you, you can include a percentage of your mortgage, utilities and other expenses in calculating how much you contribute to her support. IRS Publication 501 has a worksheet that can help you with this.

Shared support

If you share the financial responsibility for your mother with other siblings, you may be eligible for the IRS multiple-support declaration.

Heres how it works. If one sibling is providing more than half the parents financial support, only that sibling can claim the parent. But if each sibling provides less than 50 percent support, but their combined assistance exceeds half the parents support.

In that case, any sibling who provides more than 10 percent can claim the parent as a dependent. But only one sibling can claim the tax break in any given year. Siblings can rotate the tax break, with one claiming the parent one year and another the next. The sibling who claims the parent as a dependent will need to fill out IRS Form 2120 and file it with his or her tax return.

Medical deductions

If you cant claim your mom as a dependent, you may still get a tax break for helping pay her medical costs. The IRS lets taxpayers deduct money spent on a parents health care and qualified long-term care services, even if the parent doesnt qualify as a dependent.

To claim this deduction, you still must provide more than half your moms support, but your mom doesnt have to meet the income test. And the deduction is limited to medical, dental and long-term care expenses that exceed 7.5 percent of your adjusted gross income. You can include your own medical expenses in calculating the total. See the IRS publication 502 Medical and Dental Expenses, for details.
