My mother started paying prsi contributions in 2001 as a partner in the farm with my father. She is now short 1 year to bring her contributions to ten years (Ten years are neccessary) She has already asked Revenue if she could pay contributions for the year 2000, as she owned land in that year and feels that she should have been making contributions for that year. They said no. Does anyboby know if this is correct? She will only receive half a pension as opposed to a full pension as a result of this one missing year.
