Hi everyone, A lot of people have questions about the process of registering for power of attorney. Below we have some information that HMRC give out to people: There is a page on HMRC which contains helpful information about power of attorney ('Make, register or end a lasting power of attorney'). However, there is no obvious (postal) point of contact. HMRC would like any registration to be confirmed in writing. There is an address that you can write to - if you send a certified copy of the power of attorney document. Make sure that you explicitly request its return. The address is: PAYE & Self Assessment, HMRC, BX9 1AS Hopefully this is helpful for some of you!
