Hi, if you decide to do as sara says make sure that you photocopy it before you send it off to DVLA. My son sent his off after buying a new car. He had 9 months remaining on his old one so he got the form from the post office, filled it in and sent it with the Tax Disc to DVLA. A few weeks later they sent back to him saying he couldn't get his money back as he hadn't sent in the right form, which he had by the way and that they couldn't send the disc back for security reasons and that they have now destroyed it but if he wanted to appeal against it to apply again and they would look at it. To appeal he needed the disc which they had destroyed so he couldn't do anything about it. Without the disc they will not do anything and it's no good phoning as they don't want to know. So be on the safe side and get a copy. Good luck.
