Form 64-8 is the most important piece of paperwork we need to claim your tax refund for you. This is the document that lets us act as your official "agent" with HMRC. It's a lot less scary than it sounds. Basically, it's what allows the taxman to talk to us instead of you dealing with him personally, meaning you'll never have to tackle the taxman on your own again.  You can download the 64-8 form here:
