I would not have thought so. Generally PRSI linked benefits would not be affected by additional income while means tested ones would be. Isn't it the case that the Old Age (Contributory) Pension is PRSI linked while the Old Age (Non-Contributory) Pension is means tested? As such I would have expected the latter to be potentially affected by additional income whereas the former would not once one has the required PRSI contributions.But they do not effect the Old Age (Non Contributory) Pension
