Is a permanent disabled dependent (parent) qualifiying for EIC?

No, a disabled parent does not qualify you for the Earned Income Credit.

 A qualifying child may qualify you to receive EIC. The child has to be younger than age 19 at the end of the year, or age 24 if a student, or can be any age if disabled. ... 

If you're not claiming a qualifying child:

• You (or your jointly filing spouse) must have been born on or after January 1, 1950; and
• You (or your jointly filing spouse) must have been born on or before December 31, 1990; and
• You (and your jointly filing spouse) cannot be claimed as a qualifying child or dependent on anyone else's return.
