Bank of Ireland says its male staff are paid an average of 24% more than its female employees.
BOI has looked into the difference between what men and women are paid on average, regardless of their role or seniority level.
As a result, it has become the first Irish bank to publish a Gender Pay Gap Report.
Bank of Ireland says a significant contributor to its gender pay gap is imbalance at senior levels of the organisation.
Francesca McDonagh, Group Chief Executive, says “I want to progress the debate about gender diversity and that’s why Bank of Ireland is proactively reporting on the gender pay gap today.
Bank of Ireland has a gender pay gap because we have fewer women in senior roles than men. I’m focused on taking action to close the gap as soon as we can."
The bank says it is on track to meet its 50:50 gender split by 2021 which should help it address the pay gap.
