How to show income under 44ad?

Which assessment year?

Please note that "An owner of Physiotherapy center or Saloon can declare its income u/s. 44AD" but not a professional.

sir, i know section 44AD allows anything more than 8%..but my question is that can i show 30 to 35% of profit?

because somebody told me does not show more than 25%. my client income is 265000 and if i show 25% of profit than my turnover is 1000000. here qu of service tax is also arise.so what can i do?
