Form for it return

Assuming professional receipts eligible (as per section 44AA) for assessment u/s. 44ADA, you can file ITR 4_Sugam (earlier ITR4S) this year.

Thanks for your reply Mr Rambhia.  Just wanted to know one thing.

Irrespective of % of profit last year -one can take advantage of  presumptive rule. ??.

That is there is no preconditions attached to it I hope.

" rrespective of % of profit last year -one can take advantage of  presumptive rule. ??. "               YES.

"That is there is no preconditions attached to it I hope."

Only condition its eligibility as per turnover, and professional income as per section u/s. 44AA
(For resident individuals/huf/firm)  

Thanks for your reply. Yes that means  AO can call for books of accounts even though you have taken 50% .?

I think, you have not properly understood the concept.

Once the income is eligible for assessment u/s. 44ADA, and if you have declared 50% or more as  taxable income, AO cannot ask for any books of accounts, except the verification of gross receipts (rarely).
