Hi Jeff 24,
There has been a delay in updating records with voluntary contributions however payments made in November should have been processed by now.
There are circumstances where paying years prior to 2016 will not add to a State Pension award. You would need to confirm that you spoke to DWP before making the payment and that they confirmed the additional years would increase the State Pension award for your wife.
If that was the case and the funds were paid to the correct HMRC account [083220 12001004] and your wife’s account has not been updated then you will need to contact us so we can begin a payment trace via our banking team.
When the payment is traced and posted then the payment date will be honoured and your wife's pension will be updated retrospectively to the higher rate so she will not lose out financially.
