I am advised by Revenue that it has reviewed the person’s tax situation and is satisfied that there is no error and the position is correct.
The ‘deduction’ from the person’s Occupational Pension is a consequence of a reduction in their tax credits to facilitate collection of the tax due on their State Contributory Pension. The person was not previously liable to tax because their combined Occupational and Invalidity Pensions were below the exemption limit (€18,000). However, the change from being an Invalidity Pension recipient to a State Contributory Pension recipient brought their combined earnings above the exemption limit.
