  2. Hi Rohan,

    I would like to know for this Financial Year of 14-15, when is the last date for companies to fill in the details into the 26AS form.
    Maybe I am not saying it right, I jumped 3 companies since March 14 to Mar 15, but only 1 company has mentioned the details in my 26AS form, so what is the date for the last company to put in the Tax details.

    • Hello Ajay,
      Have you recieved the required info if not then here is what you need to do.
      First register at and then view your form 26AS within the website. Now start filing a new return on the site itself. You would need information from 26AS form to fill it.
