I think as per the new rules tax audit is not required EVEN IF your profit is less than 8% of turnover as long as the turnover does not exceed 2 crores, even if your income is in taxable region. The only way in which audit would be required in such a case would be if you opted for section 44AD in a previous year. Please read the sections again where you can verify the same. There are also a lot of articles online discussing this.
