Got letters today..."Thank you for applying to pay voluntary Class 3". Forgot to ask for Class 2 if eligible, but don't think we are anyway as 6 months break in leaving uk employment and commencing au employment.
Don't understand the figures, or payment. The 1st letter request £1648 for "arrears due prior to 5/10/25" with Barclays Bank deposit slip. And 2nd (dated next day) request about £15k catch-up 04/2006 to 04/2025 (which is correct based on the 22/23 NI class 3 rate) with tear off slip to attach a cheque!
So 1st letter I don't understand, £1648 arrears. For 6 months 04 to 10 2025? Or for a different period (partial years?) from last century? Anyone received something similar?
