Overview

Companies resident in Ireland must pay CT on their worldwide profits if these profits include both income and capital gains.

Non-resident companies must also pay CT if:

  • they trade through a branch or agency in Ireland
  • or
  • they are in receipt of profits or gains in respect of rental property in Ireland.

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 e-filing and e-payment.

The CT payment and filing section gives information on how companies pay and file their CT.
