Section 31 amends section 13(4B) of the principal Act. Section 31 (a)(ii) states:

...being a person born on or after 1 January 1958 who has attained pensionable age but has neither attained the age of 70 years nor been awarded a State pension (contributory)[.]

That seems to imply that if you are earning €200 or €250 per week or another modest income and on a non-contributory pension, you automatically wind up paying PRSI even though it is unlikely to be of benefit to you.
