Thanks. I've just stumbled onto a SUSI document that states that they do allow for the PS Pension Related Deduction (unlike the Medical/GP Visit Card process).
"We allow a deduction for contributions to pension schemes and pension or retirement products, forexample, Personal Retirement Savings Account (PRSA) or Retirement Annuity Contract (RAC), within the limits allowed by the Revenue Commissioners, but we exclude any ‘unrelieved’ contributions carried forward from previous years. We also allow a deduction for the public service pension levy."
