ROS / full guide
Form 11 is filed on ROS by 31 October of the following year (mid-November if you file and pay online). You enter all income, claim credits and reliefs, calculate the tax and pay the balance for the year plus preliminary tax for the current year. Register for ROS early, since a digital certificate takes several days to issue. Complex cases, such as foreign income or rental businesses, usually justify professional help.

Written by PAYEWise editorial team, plain-English tax writers working from Revenue sources. Tax review: pending appointment of a named tax-qualified reviewer. Reviewed 28 October 2026.
Answer a few questions about your 2025 situation and the walkthrough shows only the panels and fields you need, in the order the ROS screens present them. Tick each field as you enter it in the official service; nothing you type into the form itself is collected here.
These answers decide which panels and fields you need. Nothing you answer is sent anywhere.
Field labels were verified against the 2025 version of the form; Revenue may reword a label in a later version. Samples use fictional data only.

Beyond self-service?
Foreign income, a rental business, a proprietary directorship or a Revenue intervention usually justify a professional. PAYEWise does not file returns; a partner accountant can quote a fixed fee.
