My daughter has a DX of autism. Would this consider her disabled? Yes, or no

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.

[Opus 17]

For the IRS, disabled means unable to perform gainful work, due to a condition that is permanent or likely to last at least one year.  There are many people with medically recognized disabilities, who are capable of performing gainful work (working a job for money), so it really depends on the severity of the condition in your particular case.

Also, there are no extra tax credits or benefits for having a disabled child.  What disabled does for a child is,

a. allows you to claim the dependent care credit after the child turns 13, if the child is unable to care for themself while you are at work, and 

b. changes the definition of qualifying child dependent and may allow you to claim your child as a dependent  after they turn 19 or older.

c. It may change or modify the rules for claiming EITC, if you are in the right income range.
