PRSI contributions can be credited to people in a number of contexts, for example when in receipt of a Jobseekers or Illness benefit payments. Where applicable, these may be used towards PRSI-based social protection payments, including the State pension contributory. To qualify for a credit you must have worked and paid at least one PRSI contribution at PRSI Class A, B, C, D, E, or H and have paid or credited contributions in either of the last two completed tax years. Not all credits are reckonable for a State pension contributory.
Under the interim Total Contributions Approach announced in January, a person who reached pension age after 1 September 2012 and has a 40 year record of paid and credited social insurance contributions, subject to a maximum of 20 years of credits, will qualify for a maximum contributory pension where they satisfy the other qualifying conditions for the scheme.
Up to 20 years of HomeCaring credits, and/or 10 years of other qualifying credits, for example when unemployed or ill, may be used, subject to the total number of credits not exceeding 20 years.
So, for example, a person might receive a maximum pension based on 20 years paid PRSI contributions, 5 years jobseeker credits, and 15 years HomeCaring Credits, over a 50 year period.
I hope this clarifies the matter for the Deputy.
