Your pension will be calculated in several different ways- and you get the most favourable result paid as pension. Unless you insist- for whatever reason- for a different payment than the one offered to you.Are you sure this is right? ChatGPT says the following:
"Ireland does not calculate pensions solely based on your contributions relative to its domestic maximum requirement of 40 years. Instead, EU rules take into account your total contributions across all countries and calculate your share based on the portion contributed in Ireland.
If you had contributed solely to Ireland (e.g., 10 years out of 40), then you'd receive 1/4 of the maximum Irish pension. But since international contributions are involved, the pro-rata method is used instead."
It seems that being short of the 10 years does not matter using the pro rata method (per ChatGPT: "With only 9 years of Irish contributions, you fall short of this threshold. However, EU aggregation rules allow you to combine your Irish and UK contributions to meet the minimum.".
My current expected entitlement would just be smaller e.g. 9 years (Ireland) + 35 yeards (UK) = 9/44 * max Irish pension = 20.5%.
I am going to see if there are any uncounted contributions from my teenage days and go from there as it would be nice to have the round 10 years.
There is one thing I forgot. In a pro rata pension calculation your 20 Irish credits will be taken into account as well, since you made it across the 520 contribution threshold. So that gives your Irish pension part another boost.
Good luck with your search for any past and so far not registered contributions. You never know- may be something comes up!
