Claiming 80u DISABLE PERSON..

While filing ITR, it's mandatory to file form 10ia to claim deduction under section 80U

I had physically handicap certificate and standard format of medical issued by medical authorities it's enough ?

No its not enough u have to file 10ia for claiming deduction because certificate is only documentary evidence in support of form 10ia

certificate is enough to claim deduction u/s 80 U  

FLAT deduction shall be allowed irrespective of actual amount incurred 

For claiming deduction u/s 80U, ONLY Form 10-IA or a certificate in the format as prescribed vide notifications No. 16-18/97-NI.1, dated 1-6-2001 and 18-02-2002 are required to be filed alongwith the ITR. The certificates mentioned above are generally similar to Form 10-IA but require an attested photograph showing the disability... any other medical certificate is not admissible.
