If you retire at age 65 and you get a State Pension (Transition), you do not need to pay any more Voluntary Contributions.
However, even if you do not retire at age 65, you stop paying voluntary contributions once you reach age 66.
If you meet the PRSI conditions for a Widow's or Widower's Contributory Pension or a Bereavement Grant at age 66, you will remain covered for these payments.
