Paying for gaps in NI record before 2006 when living and working abroad in EU country

Are there any circumstances in which I would be eligible to make Class 2 or Class 3 National Insurance contributions retrospectively to fill gaps in my National Insurance record for the years in which I lived and worked in an EU country prior to 2006?

Hi Heidi,
Until 5 April 2025, you have the opportunity to pay NICs voluntarily for years from 2006-07 onwards.
There is no option to pay NICs prior to the 2006-07 tax year
Thank you.
