The steps below will help you to file your tax return and make a self-assessment.

Step 1: File on Revenue Online Service (ROS)

You must be registered for ROS. If you are already registered, check that your ROS certificate is renewed and you can login to ROS.

Figures from your 2019 Income Tax Return (Form 11) (if filed)
