The Central Board of Direct Taxes (CBDT) has amended the Rules relating to electronic filing of income tax returns vide Notification No.49/2010 dated 9th July 2010. The amended Rules will apply with effect from the date of notification in the official gazette.

As per the amended Rules, it is now mandatory for all companies to file income tax return electronically in Form No.ITR-6 with digital signature. Earlier, companies could file their electronic returns with or without digital signature.

Further, now all individuals and Hindu Undivided Families (HUFs), who are required to get their accounts audited under section 44AB of the Income Tax Act 1961, are also required to file their income tax return in Form No.ITR-4 electronically with or without digital signature. Earlier, this condition was applicable only to companies and partnership firms.

Accounts are required to be audited under the income tax law, if turnover or gross receipts from business exceeds Rs.40 lakh (Rs.60 lakh from assessment year 2011-12 onwards), or if turnover or gross receipts from profession exceeds Rs.10 lakh (Rs.15 lakh from assessment year 2011-12 onwards).
Mandatory electronic filing for companies requires ITR-6 with digital signature; audited individuals and HUFs must e-file ITR-4. Electronic filing rules now require all companies to file returns in Form ITR-6 with a digital signature. Individuals and HUFs subject to the income-tax audit requirement must file electronically in Form ITR-4, with or without a digital signature, where audit thresholds for business or profession are exceeded.
