Can I claim"disability" on my children if they have multiple mental issues?

Do I get a credit or deduction if my child is disabled?

If your child is older than 12 and you need to pay someone to take care of him while you work, you can say he is disabled and you can still get the childcare credit on your federal return.   Or if he is 19 or older you may still be able to claim him as a qualifying child dependent on your federal return.

Aside from those things, there is no federal tax advantage to saying that your child is disabled.   Your state tax laws might be different.

It depends. In order to claim a child as disabled, they must be deemed by a Dr as being totally and permanently unable to engage in gainful employment for at least a year or can lead to death. 

If they are able to engage in gainful employment, then no, you cannot claim them as a disabled dependent.
