Income Tax e-Filing : On line method


Income Tax e-Filing : On line e-Filing method

If your income is less than Rs 5 lakh per annum, you can fill the ITR physically.  But if your income is more than that, it is mandatory to fill it electronically.      For electronic filing, you can fill it off line and upload the XML file. For this, download the relevant ITR form from the website, fill it offline, generate XML and save it on your desktop, register on e-filing website using your PAN, login to the portal, go to e-file-Income Tax Return-upload return.

Here I am trying to explain the online e-Filing method

Open the Income Tax e-filing website using the following address:
https://incometaxindiaefiling.gov.in/
