Online surrender - Individuals who wish to surrender their PAN online can do so by logging on to the official website Income Tax Department (http://www.incometaxindia.gov.in/Pages/default.aspx) and fill in some basic information like their name, contact number, date of birth, father's name and address. They should choose which PAN they would like to retain and mention that number in the retain column. Any additional PAN which they wish to surrender can be done so by mentioning the details of such PANs. Post submission they will receive an acknowledgment number, which can be treated as proof of surrendering the additional PAN.
