Hi. I've recently received a letter from HMRC regarding making contributions from Spain where I've lived for nearly 27 years.. They've accepted my application to pay voluntary Class 2 NICs by annual payment. However, on the reverse of the letter where NIC shortfalls are detailed, every year is Class 3. So I'm confused. Am I expected to pay Class 3 for years I'm 'buying back' and Class 2 from now on? My circumstances haven't changed, and I'm convinced I meet the criteria laid out. So if those Class 3 years should be Class 2, how do I go about having things amended? Many thanks for taking the time to read this.
