Filing your Irish Income Tax Return accurately requires navigating complex reliefs, allowances, and Revenue ROS requirements. At TAS Consulting, we simplify self-assessment for sole traders, landlords, company directors, and proprietary employees across Dublin.
In Ireland, individuals who earn non-PAYE income—such as self-employed earnings, rental profits, foreign income, or proprietary directorships—are legally required to file an annual income tax return using Revenue's Form 11 via the Revenue Online Service (ROS).
Missing deductions, miscalculating preliminary tax, or filing late can lead to substantial interest charges and Revenue penalties. Our chartered tax team ensures your return is fully optimized, completely compliant, and submitted well ahead of the deadline.
You must file a Form 11 self-assessment tax return if you fall into one of the following taxpayer categories:
Individuals running their own business, contracting, or freelancing as a sole trader in Ireland.
Residential and commercial property owners generating rental income who must declare profits and expenses.
Company directors who own or control more than 15% of the ordinary share capital of an Irish company.
Individuals with significant investment income, foreign earnings, or capital gains alongside standard employment.
We ensure you claim every applicable credit and deduction to legally minimize your income tax liability.
Claiming the standard tax credit available to self-employed individuals and proprietary directors in Ireland.
Deducting allowable operational costs, motor expenses, home office utility bills, and professional subscriptions.
Deducting mortgage interest (where applicable), repairs, insurance, and management fees for landlords.

Self-assessment taxpayers in Ireland operate under the annual Pay & File system managed through Revenue ROS.

Form 11 is the official comprehensive income tax return form issued by Irish Revenue. It is used by self-employed individuals, sole traders, landlords, and proprietary directors to declare all sources of income, claim tax credits, and calculate final tax liabilities.
The standard Pay & File deadline for filing your Form 11 and paying preliminary tax falls in mid-November following the end of the tax year, provided you file electronically through Revenue ROS.
Sole traders can deduct ordinary and necessary business expenses such as motor costs, software, stationery, and advertising. Landlords can deduct insurance, maintenance, agent fees, and eligible mortgage interest.
Preliminary tax is an advance payment of income tax for the current year. In Ireland, it is safely calculated as 100% of your prior year's net tax liability to avoid underpayment interest charges.
