BPL card holder ITR..

dear colleagues,
gud evng,
ek client hai mere BPL card holder hai...
ab unka ITR file krna hai.. toh mera confusion ye hai ki unka iss year ka ITR file krne se unhe jo Benefits mil rhe hai as a BPL card holder toh vo benefits khi band toh nhi ho jaenge?? or esi koi Income limit ho BPL card holder k liye toh vo bhi share kro
