📅 Key Dates
📋 Overview
The Form 11 is the annual self-assessment income tax return for self-employed individuals and company directors. It covers all sources of income — self-employment, PAYE, rental, dividends, foreign income — and must be filed for the prior tax year.
✅ How to File — Step by Step
- File Form 11 online via ROS (Revenue Online Service) at ros.ie.
- Paper Form 11 is available but the extended November deadline only applies to online filers.
- Include all income sources: self-employment profits, PAYE income, rental income, dividends.
- Claim all allowable expenses and reliefs in the same return.
- Pay any balance of tax and preliminary tax for the current year at the same time.
⚠️ Penalty if Missed
A 5% surcharge is added to your tax liability if filed after the deadline but by 31 December (maximum €12,695). After 31 December, the surcharge increases to 10% (maximum €63,485). Interest accrues at 0.0219% per day on any unpaid balance.
