If you need to do a tax return, the deadline for submitting it for the Irish tax year (1st January to 31st December) is midnight on 31st October 2022 if you’re submitting your return on paper. If you’re submitting your return via the Revenue’s Online Service (ROS), the deadline is normally mid-November.
If you submit your return via ROS, you will also need to pay your income tax in full by mid-November.
