Revenue Note for Guidance
(1) A repayment of income tax to which a person is entitled after the granting of any personal tax credit/relief for any year of assessment is to be made at the standard rate of tax or the higher rate, as appropriate.
(2) & (3) Where a person proves that he/she had no taxable income for a year of assessment because of his/her entitlement to any tax credit, deduction or relief for that year, any tax paid by him/her in respect of his/her income for that year is refundable in full.
