evening.. I have just received a notice of assessment for a loan charge saying i have to pay by mid march. This is the first letter I have received. I never received any letters prior to this as some of the threads suggest were sent out. How can HMRC send out an assessment with calculations without any prior notification. I am very distressed and do not know what to do especially when they are also charging interest and a deadline to pay in less than 3 weeks.. Any advice or pointer would be really appreciated as I cannot comprehend even where to begin.
