It is a total minefield if you have anything other than Class A contributions. I also worked in Australia for a year so think these contributions can be combined but it still won't bring me up to the 520 and I want to use the UK ones for a pension there.
New question in relation to the OH who has similar but different mixed stamps.
179 Paid A. 181 Credits (unemployed)
Approx 6 years self-employed in Spain (not sure where I can get that record from)
1 year in Australia
The rest are D stamps which he is paying currently.
If he combined his Spanish with his A it brings him to 491 (can he use the credits to make up?) or if added Australia would be over 520.
I am also looking to buy back his UK years so he can hopefully get at least half pension there.
Would be great if there was a calculator you could just put the figures in and it did an estimate.
