Filing your 2025 Form 11 via the Revenue Online Service (ROS). Make sure to declare your 2026 Preliminary Tax alongside your 2025 self-assessment to avoid interest penalties
This brief guide provides Irish Revenue guidance on filing 2025 Form 11 Income Tax Returns, highlighting the crucial October and November 2026 deadlines. Drawing on official Revenue eBriefs, Tax and Duty Manuals, and recent Tax Appeals Commission determinations, we outline key obligations, updated form features, and practical compliance considerations for self-assessed taxpayers and tax agents.
The statutory pay and file deadline for the 2025 Form 11 Income Tax Return is 31st October 2026.
However, Irish Revenue has confirmed an extended deadline of Wednesday, 18th November 2026 for self-assessment taxpayers who use the Revenue Online Service (ROS). To qualify for this extension, you must complete both of the following actions through ROS:
Critical Compliance Note: If you only file or only pay through ROS, the extension is void. The standard 31st October 2026 deadline will apply, potentially resulting in late filing surcharges.
The same extended ROS deadline of 18th November 2026 applies to Capital Acquisitions Tax (CAT) returns and payments. This applies to gifts or inheritances with valuation dates falling in the year ending 31st August 2026.
The 2025 ROS Form 11 has been active since 1st January 2026, with major system updates deployed in April 2026. Taxpayers should note the following critical changes and tax credit increases:
Increased Personal Tax Credits for 2025
The Capital Gains Tax panel features new sections allowing self-assessed taxpayers to:
For clarity:
Requesting a deferral of CGT payments: This allows self-assessed taxpayers to claim a formal deferral of a liability directly on the return (such as the CGT deferral available on a business or farm transfer to a child under Retirement Relief).
Declaring previously deferred CGT that is now due: This enables taxpayers to report when a past deferral condition has failed or expired (such as a child selling a transferred asset before a required 12-year holding period), meaning the clawed-back tax has crystallised and fallen due.
For Clarity:
To avoid interest penalties, self-employed individuals must calculate and pay their 2026 Preliminary Tax by 31st October 2026 (or 18th November 2026 via ROS).
How to Calculate Preliminary Tax
Your payment must equal at least:
If you select “Nil” for your preliminary tax, you are officially declaring to Revenue that you anticipate your total tax liability for the upcoming year will be zero. If you underpay your preliminary tax (or declare “Nil” when you actually owed tax), you fail the statutory safe harbours. Revenue will treat the underpaid portion as overdue from the original deadline. Interest will accrue daily at a rate of 0.0219% backdated to that original due date.
When filing electronically via ROS, the Statement of Net Liabilities (SNL) is a screen that appears at the very end of the digital Form 11 submission process. You must complete the self-assessment panel, calculate the SNL, and sign/submit them together in the same session to finalize your return.

Today, 30th October 2024, the Chancellor of the Exchequer, Rachel Reeves, delivered the UK Autumn Budget. She announced the publication of the Corporation Tax Roadmap. In it, she confirmed that there would be no change to the current corporation tax rate, which is capped at 25%, until 31st March 2027. The Small Profits Rate and marginal relief will remain at their current rates and thresholds. No changes will be made to other business tax areas including:
The Government have introduced new Anti-Avoidance legislation in respect to loans to participators. From 30th October 2024, these reforms will prevent shareholders from extracting untaxed funds from Close Companies. This new legislation is being introduced to prevent loans which are repaid and then reborrowed from associated companies from avoiding the s455 charge.
Also, from 30th October 2024, the way in which capital gains are taxed when a Limited Liability Partnership is liquidated has been amended. It relates to situations where assets are disposed of to (i) a contributing member, (ii) a connected company or (iii) any other connected person. The chargeable gain accruing to the contributing member will be computed as if the gain had arisen at the time they initially contributed the asset to the Limited Liability Partnership.

The Chancellor of the Exchequer, Jeremy Hunt delivered his UK Spring Budget 2024 today. As you are aware, the Furnished Holiday Letting (FHL) regime provides UK Tax relief for property owners letting out furnished properties as short term holiday accommodations. From 6th April 2025, however, the Chancellor is removing this tax incentive in an attempt to increase the availability of long term rental properties.
According to HMRC’s guidance material, a furnished holiday let is deemed to be a furnished commercial property which is situated in the United Kingdom.
It must be available to let for a minimum of 210 days in the year.
It must be commercially let as holiday accommodation for a minimum of 105 days in the year.
Guests must not occupy the property for 31 days or more, unless, something unforeseen happens such as the holidaymaker has a fall or accident or the flight is delayed.
You may wish to consider your options before the rules are abolished in April 2025.
Options include:

Finance (No. 2) Act 2023 introduced a new Capital Gains Tax relief – “Relief for Investment in Innovative Enterprises” or Angel Investor Relief. Its objective is to encourage investment in innovative small and medium start-up businesses entities. Please be aware, however, that not all types of angel investments qualify for the new relief. An investment, for the purposes of this Angel Investor Relief will only qualify if it meets certain conditions including that it’s based on a business plan and that the company can provide certificates of qualification issued by the Irish Revenue Commissioners including a certificate of going concern and a certificate of commercial innovation. It is also important to bear in mind that the Relief will not be granted if the investor owns the investee company.
This new Capital Gains Tax Relief provides a 16% CGT rate where a qualifying investor makes a qualifying investment in a qualifying company and subsequently disposes of those shares.
This new CGT Relief applies an effective rate of 16% on qualifying gains up to twice the value of their initial investment if the investment is made by an individual or 18% if the investment is made through a partnership. As you can see both rates are very attractive when compared to the standard 33% rate of Capital Gains Tax.
There is a lifetime limit of €3 million for the Relief.
The Relief, calculated as 33% – 17% for individuals or 33% – 15% for partnerships, is available on the lowest of the following:
Conditions for the Capital Gains Tax (CGT) Relief include the following:
The criteria governing certificates of qualification are provided for under s600F TCA 1997.
For the investor, a qualifying investment under the terms of the relief includes:
For the purposes of this Angel Investor Relief, the investor must not be “connected” with the investee company or any other company within the Relief Group. In other words, in order to claim this Relief, the investor cannot be a partner, director or employee of the relevant company or have any interest in the share capital of this or any company which is a member of the Relief Group. The investor must subscribe for shares in the investee company (i) for consideration wholly in cash, (ii) by way of a bargain at arm’s length and (ii) for bona fide commercial reasons.

From 10th February 2023 the Revenue Commissioners are posting out letters to taxpayers who are currently registered for Income Tax but who have not submitted Income Tax Returns for years of assessment up to and including 2021. The individuals affected are those who are currently registered for IT but have not filed Form 11 Tax returns for years up to and including 2021. The Revenue Commissioners are now notifying them of their filing obligations as “chargeable persons” under the self-assessment rules. For further information on chargeable persons, please click: https://www.revenue.ie/en/tax-professionals/tdm/income-tax-capital-gains-tax-corporation-tax/part-41a/41a-01-01.pdf
The letters state:
“Based on a review of your Income Tax records, you have not filed any self-assessed Income Tax returns for years up to and including 2021.”
Taxpayers should start receiving such letters from 13th February onwards.
Please be aware that your Tax Agent won’t receive a copy of this notice.
In the event that the taxpayer is no longer deemed to be a “chargeable person” and, therefore, is no longer required to file an Income Tax Returns, he/she/they should cancel the Income Tax registration.
The term “chargeable person” applies to an individual who:
An individual who is in receipt of PAYE income as well as non-PAYE income will not, however, be regarded as a “chargeable person” provided:
A chargeable person is obliged to file an annual IT Return through the self-assessment system.
This can be done online via ROS or by completing a Form TRCN1 which is available on the Revenue website.
If the taxpayer is considered a “chargeable person” but has not filed Income Tax Returns up to 2021, the letter is deemed to be a Final Reminder to file all outstanding income tax returns.
If the taxpayer does not file the outstanding IT Returns or cancel the registration within 21 days of the letter, Revenue will cease the IT registration without further notice.
Once the Income Tax registration is ceased, if the taxpayer wishes to re-register for IT he/she/they will be required to submit an online application via ROS.
The Notice states:
“You should note that, where further information comes to Revenue’s attention that you were a chargeable person for any relevant tax year, Revenue reserves the right to reinstate your Income Tax registration.
The non-filing of a required tax return by chargeable persons can result in further contact from Revenue, including a follow-up compliance intervention. Non-filing of a return where required is also an offence for which a person can be prosecuted.”
