CPA Ireland If you earn money outside the PAYE system, Revenue expects a self-assessment return every year. That covers sole traders, landlords, company directors, and PAYE workers with rental, dividend, or foreign income. Miss it and the surcharge starts at 5% of your tax bill and climbs to 10%.
We take the whole job off your desk. You send us your figures, we prepare the Form 11 or Form 12, claim the reliefs you are entitled to, and file it on ROS. You get a clear summary of what you owe and a reminder before every payment date.

Income Tax Returns: your questions answered
When is the income tax return deadline in Ireland?
The self-assessment deadline is 31 October each year. If you both file and pay through ROS online, Revenue extends it to mid-November. The 2026 ROS extended date applies to 2025 income. Filing late triggers a surcharge of 5% rising to 10% of the tax due. See revenue.ie for the current dates.
How much does a sole trader tax return cost?
Our sole trader income tax returns start at €350 including filing on ROS. A PAYE worker with rental income starts at €195. The fee is fixed and quoted before we begin, so you never get an hourly bill you did not expect.
Do I need to file a return if I only have a small side income?
If your non-PAYE income is more than €5,000 gross (or €3,174 net), you are a chargeable person and must file a Form 11. Below that, you usually declare it through a simpler Form 12. We will tell you which applies after a two-minute chat.
What expenses can a sole trader claim?
You can claim costs incurred wholly and exclusively for the business: materials, tools, motor and travel, a portion of home and phone costs, insurance, accountancy fees, and more. We make sure you claim everything Revenue allows and nothing it does not.
Can you file returns for previous years I have missed?
Yes. We regularly bring clients up to date who have fallen a year or two behind. We file the outstanding returns, deal with Revenue, and agree a payment arrangement if needed so you can move on with a clean slate.
