We have a client, who is running a printing business, he arranges businesses from his own and outsource the different works to different persons, like design, paper purchase, printing, binding etc and then delivery that final product to to thier client. We have some Queries related to this : 1. can he file the return under section 44AD ? 2. We want to file return for financial year 2014-15 & 2015-2016 can we do so under section 44AD or not ? Thanks in advance
