Last night I logged onto HMRC to check my NI contributions and noticed that for the last three tax years I had gaps and had to pay them almost £2500 to make them qualifying years! This was impossible to me as I have worked for the last eight years for the same company without any breaks.
Called them this morning and the chap tried to fob me off but I told him it was impossible that it was correct.
He went off the line to talk to someone else and came back eventually and told me it was their error! He could tell me exactly how much I had earned in those years but not why the NICs were not applied to my account !!
Worth checking your records ASAP 👍
