@ Rinkal, I wish to add that it is NOT mandatory for him to claim the loss.
If assessee so desires, he may pay tax as per presumptive income even actually he is having loss.
Tax audit would apply only if he wants to claim the loss, this would be on his discretion considerig the audit fees and maintainance of the proper records.
As per S.44AB
Every person
(d) carrying on the business shall, if the profits and gains from the business are deemed to be the profits and gains of such person u/s 44AD and he has claimed such income to be lower than the profits and gains so deemed to be the profits and gains of his business and his income exceeds the maximum amount which is not chargeable to income-tax in any previous year,
get his accounts of such previous year audited by an accountant before the specified date and furnish by that date the report of such audit in the prescribed form duly signed and verified by such accountant and setting forth such particulars as may be prescribed
S.44AD(5)
Notwithstanding anything contained in the foregoing provisions of this section, an eligible assessee who claims that his profits and gains from the eligible business are lower than the profits and gains specified in sub-section (1) and whose total income exceeds the maximum amount which is not chargeable to income-tax, shall be required to keep and maintain such books of account and other documents as required under sub-section (2) of section 44AA and get them audited and furnish a report of such audit as required under section 44AB..
