The Central Board of Direct Taxes had, vide circular No.3/2009 dated 21.05.2009, allowed assessees who file their income tax returns in electronic form without digital signature to submit their verified ITR-V form, within a period of 30 days, thereafter. The ITR-V form was required to be sent to Post Bag No.1, Electronic City Post Office, Bengaluru, Karnataka-560100, by ordinary post.
It has now been decided to extend the time limit for filing the ITR-V form by relaxing the stipulations in the circular dated 21.05.2009. The ITR-V form relating to returns which have been filed electronically (without digital signature) on or after 1st April, 2009 can now be filed on or before the 30th September, 2009 or within a period of 60 days of uploading of the electronic return data, whichever is later. The ITR-V should continue to be sent by ordinary post to Post Bag No.1, Electronic City Post Office, Bengaluru, and Karnataka-560100.
