Hi HMRC, I am in procesws of paying my Class 2 contributions from abroad using a non UK bank account. What bank details should I send money to and how do I get a receipt. Some say, NI number followed by IC and surname and others state the 18 digit code??also, my letter states class 2 contributions and the amount for each year, but on the system, there are the Class 3 contribution amounts which are considerably higher on my record. Do I need to sort this before I pay, or can I just pay into the correct bank account. Thank you
