Those backlogs look as though they will still be clearing beyond 5 April 2023 . The voluntary contributions are for gaps within the last 15 years, which will be accepted until 5 April 2023, after which the voluntary contribution window reduces to 6 years.
Can you confirm that, once the payment is allocated, it will be shown as being applied at the targeted gaps in contributions according to the time when I made the payment (before 5 April 2023) rather than the time when the HMRC representative/agent processes it? In other words, will it clear the gaps I've targeted using the payment references supplied during a phone conversation with a HMRC representative?
I made a voluntary NI contribution on 23-Jan-2023 to complete the year 2006-2007 and my NI record has still not been updated. Is there some way I can check to see that the HMRC knows about the contribution and when they will credit it?
