Whether there will be single Audit Report for both the businesses? because both businesses are operated by one & the same person so we have to file single ITR 4 2. If we prepared one single Audit Report for both business then in business code (under Annx I) whether we have to fill two business codes. 3. Whether we should prepare 2 Audit Report (Two 3CD & 3CB) and consolidate it while prepare Balance sheet of Proprietor & then file single Itr4 Awaiting your reply for the above & other related point of Audit
