For the 2025 income tax year, the statutory Pay and File deadline for both filing your self-assessment (Form 11) and paying any outstanding tax is Friday, 31 October 2026. However, if you choose to file and pay via the Revenue Online Service (ROS), this deadline is extended to Wednesday,19 November 2026, provided both filing and payment are completed through ROS.
This time of year can be particularly demanding, with compliance obligations and administrative requirements intensifying. The good news is that with the right preparation, filing your self-assessment doesn’t have to be stressful. To help you meet your obligations efficiently and accurately, we have prepared a concise guide outlining the main steps to complete and submit your self-assessment return well before the deadline.
Who should complete a self-assessed Income Tax return:
- You are self-employed
- You have profited from share options or share incentives
- You have Non-PAYE income over certain limits,
- Where you have income from
- rental properties
- investments
- foreign income;
- maintenance payments;
- fees that are exempt from PAYE
When should you complete a self-assessed income tax return?
The deadline for the 2025 Income Tax return is 31 October 2026 for both the Income Tax balance due for 2025 and Preliminary Tax for 2026.
The ROS Extended Pay and File deadline for online returns is 19 November 2026. The extended deadline is for taxpayers who file a 2025 Form 11 Income Tax return and make the appropriate payment through ROS. Where only one of these actions is completed through ROS, the extension does not apply.
For late payments, you will be charged interest for each day (or part of a day) past the deadline.
How Do You prepare & Complete A self-Assessed income tax return?
- Be organised and gather all of your business receipts, invoices, bank statements. The following is a summary of the information you will need:
- All business and trading receipts
- Details of all rental income
- Details of any mortgage payments relating to a rental property

If you wish to avail of the extended ‘File and Pay’ deadline you must register for ROS online prior to the deadline and complete both the returns and payments by 19 November. Revenue provides a number of helpful guides online; however you may wish to consider appointing an accountant if you are not comfortable completing the returns yourself.
Tip! Reducing your tax bill:
One way of reducing your tax bill is to make a pension contribution for 2025 prior to the deadline and avail of full tax relief. The pension contribution must be received by your pension provider prior to the deadline in order to be allowable in the Income Tax return for the previous year. Therefore, please ensure you talk to your financial advisor in advance of the deadline.
Tip! Capital Acquisitions Tax:
Beneficiaries who received gifts or inheritances with valuation dates from 01 January to 31 August 2026 must also make a return and pay tax due prior to 31 October 2026. For valuations from 01 September to 31 December you must make the tax return prior to 31 October next year. Valuation dates vary depending on the gift or inheritance, please see www.revenue.ie for full definitions of these dates.
Tip! Local Property Tax:
If you owned a residential property on 01 November 2025, you are liable for LPT for 2026 on that property, even if you do not usually live in that property. You will need to ensure that you meet your LPT obligations. In order to remain compliant, you should again follow the Revenue guidelines here: https://www.revenue.ie/en/property/local-property-tax/index.aspx
Tip! Capital Gains Tax:
If you dispose of an asset you must pay Capital Gains Tax (CGT) on the gains/profits on the disposal of that asset. CGT returns are due as follows:
- For disposals between 1 January and 30 November (the initial period), you must pay CGT by 15 December of the same year.
- For disposal from 1 December and 31 December (the later period), you must pay CGT by 31 January of the next year.
