What do I do with the forms?

Once you have printed and signed the 64-8 Authorising Your Agent form you need to send it back to us by post as quickly as you can to get your refund claim underway.

We know this seems a little bit old fashioned now, but it’s a legal requirement that we have a physical copy of the signed form with your name on. Send it back by writing Freepost RIFT on any envelope - it'll get safely to us at no cost to you.
