Please read this interesting article on tax benefits for families with special needs children. Disabled children can qualify for dependency exemption and other benefits regardless of their age.
“Further complicating the situation, parents with special needs children are often unaware of possible tax benefits that are available and forgo hundreds, if not thousands, of dollars in potential tax deductions and credits. Michael A. O’Connor, an attorney who has written extensively on this topic, believes that 15% to 30% of families with a disabled child have one or more unclaimed tax benefits. Among these potential tax benefits are deductions or credits for the dependency exemption, medical expenses, special instruction, capital expenditures for medically required home improvements, impairment-related work expenditures, and the earned income tax credit.”
