Voluntary Class 3 NIC - Extended Deadine to 05/04/2025

HMRC, please can you help? So, to be absolutely clear on so much confusing information this is my situation. I need to make up 5 years for a full State Pension. My online NI record shows: 2019/20 shortfall £697.40 which may increase after 31/07/2023 2020/21 shortfall £795.60 which may increase after 31/07/2023 2021/22 shortfall £800.80 which may increase after 05/04/2024 Does the recent extension mean that I can delay payment for these years until nearer 05/04/2025 but I will still pay the amounts quoted above? Or will the amounts increase? I also intend to fill 2022/23 which will cost £824.20 and I understand that rate is also good until 05/04/2025 and 2023/24 at a cost of £907.40 good until 05/04/2026. Thank you

I'd be grateful if you would answer specifically the question I pose above, not just copy and paste the confusing information on the gov.uk website. Many thanks

Hi,
Yes, that is right.  
The payments for 19/20, 20/21, 21/22 and 22/23 will be payable at the rates below until 5th April 2025, following the recent extension to 31/07/23 deadline.  
You won’t be able to make payment for 23/24 tax yearr until the end of the tax year ie after 05/04/24.
 HMRC always recommends that our customers check with Future Pension Centre before making any payments though, as you need to make sure that they will benefit your State Pension.

Thank you.
