Missing NI contributions any change in deadlines from being able to pay 10 years back

I was born in 76, and was in full time education between 18 to 24. When i hit my 16-18 birthdays in March 1991-1994 i received NI credits which i understand. I did a adhoc summer job in 1994/5 and 1995/6 I asked for a forecast in 2005 and paid for other missing years but couldn't for these 2 - has the deadline to pay for missing years changed or is it still fixed (i think for 10 years previously judging i was able to pay for the years 96/97 onwards back in 2005 when i asked for a forecast). I wanted to see if i could pay for those missing years of 1994/95 and 1996/7 basically if anything has changed in timescales?

Hi,

Thank you.

On my NI record there is one year that is being reviewed to see if it’s considered a full year or not. It has been like this for ages and I’d like to know when it will be updated so that I can see whether I need to pay voluntary contributions to ensure it’s a full year. Is there a date when this will be updated/how long does it generally take to review this?

Hi C. Crowl,
If you’ve been employed in the UK and National Insurance contributions have been deducted from your salary during the 2023-2024 tax year then these contributions should be
shown on your Personal Tax Account (PTA) any time now.  
If your contributions are not recorded on your PTA by the end of the year or if your query is about something else then please call our National Insurance Helpline on 0300 200 3500
(from the UK) or +44 191 203 7010 (from overseas) and they will help you further.
Thank you.
