A UK pension that is similar to a social welfare pension in this State is not liable to USC. Other than such pensions, however, Irish resident individuals are liable to pay tax, including universal social charge (USC), on income arising from Irish and foreign sources, including occupational pensions.
Individuals aged 70 years or over, whose aggregate income for the year is €60,000 or less, will only pay USC at rates of 1.5% on the first €12,012 of income and a maximum rate of 3.5% on the balance in 2015. These rates were 2% on the first €10,036 of income, and a maximum rate of 4% on the balance in 2013 and 2014.
However, the UK and Ireland have a convention in place to eliminate double taxation on income arising in one State where the individual is resident in the other State. Irish tax, under the terms of the convention, includes income tax and USC. If the individual has paid UK tax on the income, a credit is allowed in computing the Irish income tax and USC liabilities to ensure that the income is not subject to double taxation.
