The ITR can be filed both physically & electronically. For e-filing, download the government utility from the Income Tax portal (in excel format or java utility). Complete all the fields with the information required, pay the taxes due and generate the XML. You can upload this XML on the government portal by logging into your account. Once the XML has been uploaded, download the acknowledgment in ITR-V. This ITR-V can be verified, either by using EVC code or can be sent by courier to CPC Bangalore for further processing.
