Hi
By what i understand of the section i have to disagree with Ms Alamelu
As i understand the line is to be understood as under
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)(which means the one who has turnover below Tax audit limit and claims profit below 8% from said income)
and whose total income exceeds the maximum amount which is not chargeable to income-tax,(which means the person with income above basic exemption limit of income tax (its usually for individual, HUF etc)
shall be required to keep and maintain such books of account and other documents as required under sub-section (2) ofsection 44AA and get them audited and furnish a report of such audit as required under section 44AB.
So I am of view that section 44AA and 44AB does apply to your business and have to get the books audited
