Doubt in 44ad

I think you can! You only need to be careful when you're declaring income u/s 44AD when the profit is less than 8%. Hope this helps!

Yes you can withdraw the presumptive taxation scheme and file normal return with the following consequences:

1) You have to keep proper books of accounts u/s 44AA.

2) For next 5 years you will not be eligible to opt for Sec.44AD.

3) If turnover exceeds Rs.1 Crore, according to sec.44AB tax audit has to be done.

no if you once opted presumptive taxation scheme you will have to declare 8% of turnover ....
however if you claiming your profit is less than as per presumptive scheme then you will have to get audited your books of account under section 44AB...
here is a exception of above provision ----i.e..
if the assessee's turnover is less then or upto 250000 than he need not get audited their book of account.......as much as you will declare turnover shall be consider as chargeable income ... on which tax shall be levied...
