Corporation Tax (CT)


Companies resident in Ireland must pay CT on their worldwide profits. These profits include both income and capital gains. Non-resident companies that trade through a branch or agency in Ireland must also pay CT.

The CT that a company pays is charged according to Income Tax rules. Chargeable gains are calculated in accordance to Capital Gains Tax (CGT) rules.

A company must use the Revenue Online Service (ROS) to file its return and pay any tax due under Mandatory eFiling and ePayment.
