You have to show minimum 8% income.So you can file return u/s 44AD by showing higher income.

8% is for other transaction 

6% is for digital transaction

you can show higher amount as you want

Thanks to correct manoj

What if we show 8% only and not 35% ?
Assuming books of accounts are prepared but we op for no account case in it return. is it fine if we show Rs180000 as profit from business and file I. t.return. And the detailed profit and loss contains profit of 3.5 lacs. What could be possible issues ?

No issue at all.You can do so

Can a CA certify such profit and loss Account having Rs.350000 profit accompanied with Income tax return Rs.180000 ? What care should be taken while signing such accounts ? Eg. All these have to submitted to bank for loan purposes. Any specific report on the letterhead of CA ? Any note on the financials ?

If amount of tax suits you it will be better to show higher percentage because ur books money will increase otherwise balance will be out of books
