I lived abroad 2014 to 2022 in Europe. I now live and work in the UK. HMRC have confirmed in a letter I can retrospectively pay Class 2 NICs for the years I was abroad, and they have confirmed the amounts due for each year 2014 to 2022. 2 questions: do I pay to 08-32-20, 12001004 as per the website, or do I pay to 20-20-48 30944793 as I was told on the phone? And how do I show which year I wish to pay - I only want to pay for 1 year 2021-2022? Thank you
