Digital signature mandatory?

If it is your tax audit then it is mandatory to opt for DSC otherwise it is not mandatory for individuals & HUF.

DSC is mandatory for filing of returns of individuals who are required to get their accounts audited u/s 44AB.

[Accounts are required to be audited under the income tax law, if turnover or gross receipts from business exceeds Rs.1 crore from assessment year 2013-14 onwards  or if turnover or gross receipts from profession exceeds Rs.25 lakh from assessment year 2013-14 onwards ]
