The seafarer's allowance, which is provided for under section 472B of the Taxes Consolidation Act 1997, applies to the shipping industry and under EU rules constitutes a state aid. The allowance of €6,350 at the marginal rate applies to seafarers who are at sea on a voyage to or from a foreign port for at least 161 days in total in a tax year on a passenger or cargo ship which is registered in an EU member state's shipping register. Other EU states have a similar concession.
The EU has exempted the shipping industry from certain state aid provisions and has published guidelines, OJ C 205 of July 1997, to this effect. There is no similar exemption for the fishing industry and the introduction of a marine fishing allowance would breach the EU guidelines.
