Anjali , i agree that with the part that 44AD exclude Brokerage & Commission .
But i don't think job work charges qualifies within the meaning of BROKERAGE AND COMMISSION .
"commission or brokerage" includes any payment received or receivable, directly or indirectly, by a person acting on behalf of another person for services rendered (not being professional services) or for any services in the course of buying or selling of goods or in relation to any transaction relating to any asset, valuable article or thing, not being securities
Moreover if it had been covered in " BROKERAGE AND COMMISSION " we would be deducting TDS on u/s 194H, but do we do that, NO we deduct TDS u/s194C .
let take it practically , do you think income of job worker like tailor , carpenter etc should be covered in BROKERAGE AND COMMISSION , I DONT'T THINK SO.
so in MY OPINON job worker can file ITR 4S.
