Capital Acquisitions Tax (CAT)

Form IT38

You may complete the IT38 form through Revenue Online Services (ROS) or myAccount.

If using ROS, we recommend that you complete the IT38 form using the ROS Offline Application and upload the saved file online. The online version of the form does not save to Work in Progress and it may time out before you have entered all the details.

If you create the original IT38 in the ROS Offline Application, this simplifies the process if you have to make any amendments later.

For further information, please visit the ROS Offline Application section.


You can pay CAT for yourself or on behalf of a beneficiary using the following methods.

If you are a ROS customer, you can pay by:

  • Single Debit Instruction (SDI)
  • Credit or Debit Card.

If you are using a TAIN certificate, you can access these payment options from any ROS Client Services page.

Customers not registered for ROS can make a payment through myAccount.
