The majority of staff employed by my Department at the embassy and consulates in the US are not affected by the 1997 US-Ireland double taxation agreement, as they enjoy income tax exemption in the United States and pay tax in Ireland. However, a small number of staff are affected and the Department has implemented a new arrangement under which those staff now liable for income tax are compensated for their loss of salary through a non-pensionable supplementary tax allowance. The allowance is set locally and is calculated based on the federal, state and local income tax rates in operation. As a result, staff affected by the double taxation agreement are in receipt of salaries similar to those of their counterparts who are not affected by the agreement.
