tax deductions

Dear Liz: The writer who wrote in about her mother’s medical bills should check to see if she took those bills as a schedule A deduction on her 2010 and 2011 federal tax returns. She still has time to amend those returns, if that is useful.

Answer: That’s a terrific suggestion. The writer’s mother may qualify as her dependent if the writer covered more than half of the mother’s necessary living expenses, including in-home care, and the mother’s situation met certain other requirements, such as not having gross income in excess of IRS limits. Gross income does not include nontaxable Social Security checks or other tax-exempt income. The limits for gross income were $3,650 in 2010, $3,700 in 2011, $3,800 in 2012 and is $3,900 for 2013, said Mark Luscombe, principal analyst for CCH Tax & Accounting North America.

Even if the mother didn’t qualify as a dependent, a deduction may still be possible, Luscombe said. As long as the writer provided more than one-half of the mother’s support, the writer might still be able to claim a deduction for medical expenses if all of the writer’s medical expenses, including those paid for the mother, exceed 7.5% of the writer’s adjusted gross income in 2010 and 2011. (The medical expense deduction threshold increased from 7.5% to 10% in 2013 for those under age 65.)
