Step-by-Step Guide
Log In to Your Account
Access the appropriate Revenue system for your situation.
Check Pre-Populated Information
Revenue pre-fills some information from employers and financial institutions. Review this carefully - it's not always complete or accurate.
Enter All Income
Report all income sources accurately.
Claim Your Deductions
Enter all allowable deductions to reduce your taxable income.
Apply Tax Credits
Ensure all applicable credits are claimed.
Review the Calculation
The system calculates your liability. Check all income is included, credits applied, and numbers look reasonable.
Submit Your Return
Once satisfied, submit your return. Save or print the confirmation for your records.
Pay Any Tax Due
If you owe tax, pay through ROS. Self-employed taxpayers also pay preliminary tax for the current year.
Pro Tip: Save as You Go
Both ROS and myAccount allow you to save your progress. Don't feel you need to complete everything in one sitting - save regularly and come back if needed.
Common Questions
Can I amend my return after filing?
Yes, you can amend returns within 4 years of the filing deadline. Use the "amend return" function in ROS or myAccount.
What if I can't pay the tax due?
Contact Revenue to discuss payment arrangements. It's better to file on time and arrange payment than to delay filing.
How long should I keep records?
Keep all records for 6 years from the end of the tax year they relate to.
Don't Miss the Deadline
Paper returns must be filed by 31 October. Online (ROS) filers get an extension to mid-November. Late filing results in surcharges of 5-10% of tax due plus interest.
