What Is a Form 11 and Who Needs to File One?
A Form 11 is the name of the Irish Income Tax return required to be completed by anyone deemed to be a chargeable person. A chargeable person is anyone whose income is not wholly covered by the PAYE system. You are deemed to be self-assessable, meaning you are responsible for declaring your income by filing a Form 11 income tax return.
The most common examples of chargeable individuals required to complete a Form 11 include landlords, self-employed or sole traders, freelancers, retirees with investment income, company directors and PAYE earners with side income over certain thresholds. See more on “who is it for page”.
The Form 11 is submitted annually either by paper or more commonly online via Revenue’s ROS system. It covers a calendar year, with the Form 11 due to be submitted by the 31st October the following year (although an extension into early November is usually granted for online returns. See “deadline page”). When filing your Form 11, you also need to make a preliminary tax payment for the current tax year. For example, by the 31st October 2025 you must file your 2024 Form 11, pay any balance of tax owed for 2024, and make a preliminary payment based on your estimated 2025 liability.
