Class 2 in SA Voluntarily

Hi, I submitted 22/23 tax return on 4th January 2024 and paid voluntary class 2 national insurance. However, when checking my personal tax account it still states that year is not full. How long should I expect for this to be updated and for the payment to reflect on my national insurance record? Thank you.

Hi CheesyPanda,
If your Self Assessment record is set up to include voluntary Class 2 payments as part of the calculation and is paid on time, then the voluntary payment will filter through to your NIC record.
We cannot advise how long this will take.
If you SA record is not set up to accept voluntary Class 2 NIC, then it will not form part of the calculation, even if you tick the voluntary Class 2 NIC box.
In this case, you will need to contact the NIC helpline on 0300 200 3500, to arrange a voluntary payment.
They will be able to update your self assessment record to accept voluntary payment in the future.
Thank you.
