Can I get a tax deduction for covering a non dependent family member medical expenses?

[Bsch4477]

You can deduct those medical expenses for a non dependent only if :

An individual you would have been allowed to claim as a dependent except one of these applied:

• He or she received gross income of $4,300 or more in the year.
• He or she filed a joint return for the year.

In IRS Publication 502, "Medical and Dental Expenses," see "Dependent" under "Whose Medical Expenses Can You Include?" It explains exceptions that, in certain cases, allow you to deduct medical expenses you paid for someone who is not your dependent. You can read it online at the first link below, or download the PDF of the publication from the second link. "Whose Medical Expenses Can You Include?" is on page 3.

In the section of Publication 502 that I referred you to, note that there are other exceptions besides the ones that Bsch4477 mentioned. Read the whole "Dependents" section.
