Dear Sir 
Pls let me know that I have a Partnership firm with Software company
 as 100% EOU registered from SEZ
 i am filing return since last 13 year under 44AD 
but during discussion with CA i am confused and having query 
I may file return under 44AD if my turnover is under 2 Crore (which is 1.3 crore) 
which ITR form i should use? ITR4 or ITR5 
do we have to show case complete P&L & Balance sheet ?
or only the minimum info 
I am maintaining books of account for my purpose bot not yet declared 
and after deducting depreciation of 2.5Lac book profit is 6.5% 
We are registered and filing GST return timely too. 
I need your input if possible for same it would be great if you may guide us?
