Hi,
We are sorry to hear that you been unable to speak to an advisor on our helpline, our lines are extremely busy at present.
We can confirm that your father can still make a payment for the 2008 to 2009 year although he has now reached state pension age. The deadline for paying for that tax year is 31 July 2023.
However, he must confirm with the Department for Work and Pensions that paying for that year will increase his pension before he sends any payments to HMRC. It is important that he does this. If he paid for that year without checking and his pension did not increase, he would not automatically be entitled to a refund. We have provided their contact numbers below, however their phone lines are also extremely busy at present.
0800 731 0175 for customers under state pension age.
0800 731 0469 for customers over state pension age.
Once your father has confirmed that paying for that year will increase his pension, he can make a payment to HMRC by online banking or by cheque. Please see the attached link on how to pay by online banking:
Pay voluntary Class 3 National Insurance
Or by cheque:
By cheque through the post
The only way to pay by online banking is to obtain an 18 digit reference number from HMRC. The contact number for obtaining the 18 digit reference number is 0300 200 3500. If you are still having problems getting through on that number, your father can make a payment by cheque without an 18 digit reference number.
Thank you.
