The FISC Subcommittee on Tax Matters will hold a public hearing on the tax implications of the Trump administration’s policies next week on Tuesday 23 September 2025. The hearing is an opportunity to both consider the evolving dynamics of EU-U.S. tax relations and to reflect on how the EU can safeguard its interests in a rapidly changing global context.

The OECD has published its annual report on Tax Policy Reforms for 2025. The report covers the tax policy reforms introduced or announced in 2024 in 86 member jurisdictions of the OECD/G20 Inclusive Framework on Base Erosion and Profit Shifting (BEPS), which includes all OECD countries.

Revenue has restructured its guidance on Capital Acquisitions Tax (CAT) and has published two new manuals, the CAT Administration Manual and the CAT Manual which replace the existing guidance. Apart from minor changes, the contents in both manuals have been taken directly from pre-existing guidance. Revenue has confirmed that links to the documents in the manuals will be updated over the coming weeks and a table has been provided which lists the titles of the documents in the new CAT manual and indicates the source of the guidance contained in each document. The new CAT Administration Manual contains the following details: CAT Part 01 - Introduction to Capital Acquisitions Tax CAT Part 02 - Statement of Affairs (Probate) Form SA.2 CAT Part 03 - The Self-Assessment Tax Return (Form IT38) CAT Part 04 - Certificates of Discharge Guide to Capital Acquisitions Tax Compliance Intervention The new CAT Manual covers the following topics: Part 02 - Gift Tax Part 03 - Inheritance Tax Part 04 - Value of Property for Tax Part 05 - Provisions relating to Gifts and Inheritances Part 06 - Returns and Assessments Part 07 - Payment and Recovery of Tax, Interest and Penalties Part 09 - Exemptions Part 10 - Reliefs Schedules

Revenue has published the Karshan Disclosure Opportunity Guidance, outlining detailed information regarding possible settlement arrangements arising from the Supreme Court’s decision in Revenue Commissioners v Karshan (Midlands) Ltd. This follows the publication in May 2024 of the Revenue Guidelines for Determining Employment Status for Tax Purposes, which was update to reflect the decision in Karshan. In a recent press release, Revenue notes that “the judgment changed the understanding of the correct legal principles and legal tests to apply in determining whether an employer had correctly classified workers as employees or as self-employed”. Where a business or employer deems that it is necessary to make a disclosure and that disclosure can be treated under the new guidance, the disclosure must be made no later than Friday, 30 January 2026. In the new guidance note, Revenue states the following: “Revenue invites employers impacted by the Supreme Court ruling to make a disclosure in respect of 2024 and 2025. Revenue will treat any adjustment of liability in respect of both years as a “technical adjustment” as provided for in the Code of Practice for Revenue Compliance Interventions. This means that Revenue will not consider liabilities to have arisen from either deliberate or careless behaviour and a tax-geared penalty shall not apply to any liabilities to Income Tax, USC and PRSI in respect of these years. In addition, fixed penalties will not apply.” At the time that the judgment was released, the Institute engaged extensively with Revenue through the Tax Administration Liaison Committee. You can find links to the various meetings where this issue was discussed below: Minutes of TALC Direct and Capital Taxes Sub-Committee - 30 November 2023 Minutes of TALC Direct and Capital Taxes Sub-Committee - 29 February 2024 Minutes of TALC Direct and Capital Taxes Sub-Committee - 25 April 2024 Minutes of TALC Direct and Capital Taxes Sub-Committee Meeting - 12 June 2024 Minutes of Main TALC Meeting - 27 June 2024 As part of our engagement with Revenue through TALC, the Institute, under the auspices of the CCAB-I also provided feedback on the judgment. While our understanding did not reflect Revenue’s interpretation in certain areas, the process provides the appropriate forum for a detailed understanding of the judgment and its implications.

Revenue has published new guidance on the registration process for Pillar Two taxes. Entities must register with Revenue for the relevant taxes within twelve months following the end of the first fiscal year in which they fall within the scope of Pillar Two taxes which includes taxes arising under the Income Inclusion Rule (IIR), the Undertaxed Profit Rule (UTPR), and/or the Qualified Domestic Top-up Tax (QDTT). The guidance outlines the relevant Pillar Two registration obligations and provides information on the registration hub and managing the various registrations. The registration hub is now live and the deadline for in-scope entities with a fiscal year ending on or before 31 December 2024 to register with Revenue for Pillar Two is 31 December 2025 Entities are also required to register for the Top-up Tax Information Return (TIR) through the registration portal, enabling them to inform Revenue whether the TIR will be filed in Ireland or by a Designated Filing Entity in another jurisdiction. Revenue issued letters to Irish Ultimate Parent Entities (UPEs) in mid-August 2025 regarding the registration process and a second phase of letters are due to be issued soon to the constituent entities of the Irish UPEs. Further details on the registration portal and the dedicated Revenue Pillar Two hub are outlined in our recent news item.

Ahead of HMRC’s Annual Stakeholder Conference which takes place in London tomorrow, the Institute has written a letter of introduction to HMRC’s new CEO setting out four key issues on its agenda. The Institute will be represented at the conference and will report back on the conference in next week’s Chartered Accountants Tax News. This year the conference theme is “Navigating the future together: the Transformation Roadmap in Action”.  The four key issues covered in the letter to JP Marks are: The Institute’s campaign for a lower rate of corporation tax in Northern Ireland, The tax burden and complexity arising from cross-border and remote/hybrid working, Tax simplification and the lack of progress in this area, and Making Tax Digital for Income Tax and the implementation of mandatory tax adviser registration from 1 April 2026. 

In a detailed miscellaneous update this week which you can read more about below, HMRC is seeking research participants for its project looking at multi-factor authentication (MFA) for agents.

HMRC seek research participants for MFA HMRC is seeking agent volunteers to participate in its project on introducing MFA for agents. HMRC has therefore asked us to share the following message which provides more information: “Request for user research volunteers for MFA discussions HMRC is expanding the implementation of multi-factor authentication (MFA) for all agents and want to engage with specific agent groups about its introduction. HMRC already uses MFA to enhance the security of Government Gateway accounts for all individuals and organisations, adding an extra layer of protection. We want to work collaboratively on the introduction of MFA so we’re looking for your help in identifying agents to take part in individual user research sessions. These will provide an opportunity for us to gather insight on the working processes within different types of agents and the operational requirements they need for implementation. We would like to speak with 6-8 representatives from each of the following agent types: Group 1 – Sole practitioners and micro firms (0-9 employees), Group 2 – Mid-sized and smaller firms (10-49 employees), and Group 3 – Large agents (50+ employees). Sessions are expected to last 60 minutes running across the month of September. When responding to us please reply to: customerengagementforums@hmrc.gov.uk and include ‘MFA volunteer’ in the subject line. Please also indicate the size of the firm the volunteer represents by indicating which of the 3 groups you belong to when replying.”

With just over six months to go to the commencement of Making Tax Digital (MTD) for Income Tax, the Institute is inviting tax agents and businesses affected by this change to take a short eight question survey. The survey is being used as a temperature check to assess readiness and will be open until the end of this month. Its results will be compared with an earlier survey from April this year and will enable us to present direct evidence of the challenges to HMRC. Take the survey now. We also remind readers that the second of two CPD webinars on MTD for Income Tax takes place later this week, tomorrow Tuesday 16 September. This webinar will be delivered by HMRC’s MTD team.

In this week’s Sustainability/ESG Bulletin read about sustainability in the Irish Government’s Action Plan on Competitiveness and Productivity. Also covered are recommendations from the Climate Change Advisory Council on solar PV, a new report on the Voluntary Nature Market in Ireland, the Extended Producer Responsibility Scheme in Northern Ireland, Spain’s State pact to tackle the climate emergency – including by mandating ESG reporting – and the landmark partnership between the ISO and GHG Protocol to co-develop new standards for GHG emissions accounting and reporting, along with the usual articles, resources and upcoming events.   IRELAND Sustainability in the Government’s Action Plan on Competitiveness and Productivity The Department of Enterprise, Tourism and Employment has this week published an Action Plan on Competitiveness and Productivity, with 85 actions for enhancing Ireland’s competitiveness and productivity performance. Among the six themes into which these actions are grouped is “growing sustainable Irish businesses and boosting regional development”.  Read more about sustainability in the Action Plan. Climate Change Advisory Council calls for accelerated roll out of solar PV The Climate Change Advisory Council (CCAC) in its recently published Annual Review 2025 has called for an accelerated rollout of solar PV for commercial and public buildings to help manage energy costs. With increasing challenges around global competitiveness, the Council warns that although industrial emissions reduced by 4.6 percent in 2024 – mainly due to a decline in cement volumes – Ireland has not yet broken the link between production levels and emissions in the industrial sector. The Council also warns that the volume of waste generated remains too high with Ireland’s circularity rate of 2.3 percent falling well below the EU average of 11.8 percent. Voluntary nature market could unlock private finance for Irish ecosystems, report finds A Voluntary Nature Market featuring nature ‘credits’ has the potential to close the multi-billion-euro nature funding gap in Ireland, according to a new report published last week by Trinity College Dublin and BiOrbic Research Ireland Centre for Bioeconomy.  The report, ‘The Voluntary Nature Market in Ireland: State of Play, September 2025’, maps out the key challenges and opportunities in Ireland’s Voluntary Nature Market and calls for the development of a high-integrity, transparent, and durable market. Commenting, the report’s lead author Orlaith Delargy said: “The EU estimates a shortfall of €37 billion per year between current spending and what’s needed to meet our nature goals. To address this gap, new ways of financing action on the ground are needed … A Voluntary Nature Market, similar to the Voluntary Carbon Market, could channel private investment to local projects that restore ecosystems and support communities.”   NORTHERN IRELAND/UK Small businesses urged to register for Extended Producer Responsibility scheme For the first time companies in Northern Ireland with an annual turnover of more than £1million and responsibility for over 25 tonnes of packaging each year need to record and report their packaging data under the Extended Producer Responsibility (EPR) scheme, a UK-wide reform of an existing Producer Responsibility scheme for packaging. Among its core aims are increasing recycling rates of packaging, reducing waste and non-recyclable material being placed on the market and shifting the costs of managing household and street-binned packaging waste to producers of packaging. The new EPR scheme also marks significant changes for larger organisations in Northern Ireland which are now obliged to report recorded data every six months and will for the first time be liable for the full cost of managing packaging waste including costs associated with the collection, sorting, and treatment of household waste. Renewable electricity consumption – Northern Ireland   A total of 43.1 percent of total electricity consumed between June 2024 and June 2025 was generated from renewable sources located in Northern Ireland. This represents a decrease of 2.8 percentage points on the previous 12-month period (year ending June 2024). The ‘Electricity Consumption and Renewable Generation in Northern Ireland: Year ending June 2025’, which published this week, details the percentage of electricity consumption in Northern Ireland generated from renewable sources and includes information on the type of renewable generation. Of all renewable electricity generated within Northern Ireland over the 12-month period 81.7 percent was generated from wind down from 82.3 percent the previous year. EUROPE Spain mandates ESG reporting The Government of Spain has presented its proposal for a State Pact to tackle the climate emergency, in which it reportedly plans to make carbon reporting mandatory. Royal Decree 214/2025, establishing new national carbon reporting framework, represents Spain's most ambitious corporate carbon reporting mandate to date, locally implementing key elements of the Corporate Sustainability Reporting Directive (CSRD). The regulation is to take immediately effect, with first reports due in the 2026 for 2025 emissions data. EU Parliament adopts simplifications to the EU carbon leakage instrument The EU Parliament has given its final green light to changes to the Carbon Border Adjustment Mechanism (CBAM). The changes, which are part of the Omnibus I simplification package presented on 26 February 2025, are part of simplification efforts to reduce the administrative burden for SMEs and occasional importers. A new threshold will exempt 90 percent of importers from the EU CBAM rules and procedures for imports covered by CBAM rules will also be simplified. The statement claims that climate ambition maintained as 99 percent of CO2 emissions from iron, steel, aluminium and cement imports will still be covered. WORLD ISO and GHG Protocol announce strategic partnership for emissions accounting The International Organization for Standardization (ISO) and Greenhouse Gas Protocol (GHG Protocol) have announced a landmark partnership to harmonize their existing portfolios of greenhouse gas (GHG) standards and to co-develop new standards for GHG emissions accounting and reporting. The partnership will produce a common global language for emissions accounting, which will accelerate progress towards decarbonisation. The partnership represents a fundamental shift toward integration and co-development, enabling users to rely on a coherent framework and reducing potential confusion in the market. More information about ISO is available at www.iso.org. More information about GHG Protocol is available at www.ghgprotocol.org.

The Financial Reporting Council has issued two new Factsheets to support entities applying FRS 102 and FRS 105. There are currently eleven factsheets in issue and each Factsheet aims to assist stakeholders by highlighting certain requirements set out in FRS 102 and other FRSs. The following Factsheets have been issued; FRS Factsheet 12 - Presentation of the financial statements- This Factsheet sets out the financial statement presentation options available to entities. While the factsheet is primarily focussed on FRS 102, the considerations for entities applying FRS 101 and FRS 105 are also addressed. The Factsheet also considers the option available to FRS 102 preparers to adapt the format of the profit and loss account and balance sheet. FRS Factsheet 13 - The Going Concern Basis of Accounting for Small Companies and Micro-entities- This factsheet aims to assist directors of small companies and micro-entities on how to address going concern- both in terms of performing going concern assessments and in preparing financial statements disclosures about their conclusions on going concern.

  The Department of Enterprise, Tourism and Employment has this week published an Action Plan on Competitiveness and Productivity, with 85 actions for enhancing Ireland’s competitiveness and productivity performance. Among the six themes into which these actions are grouped is “growing sustainable Irish businesses and boosting regional development”, under which are outlined the actions intended to support the development of a sustainable, resilient enterprise environment. The Action Plan is clear that decarbonisation and economic growth are not mutually exclusive, stating that “Our businesses, customers, workers, and the communities in which they are embedded, rightly expect that new industrial developments and successful Irish enterprises can and will operate in a manner consistent with the national objective of net zero emissions by 2050, and an ambitious trajectory of decarbonisation to that target.” As the broader trend toward sustainability expectations of companies is set to accelerate, it is encouraging to see the focus in the Action Plan on the alignment of sustainable Irish businesses with enterprise growth. Commenting, Susan Rossney, Institute Sustainability Advocacy Manager, said "Long term, organisations will only increase the alignment of their operations with global sustainability objectives. The Plan’s assertion that decarbonisation is not just an environmental imperative but a source of economic resilience, cost savings, and competitive advantage for industry and SMEs is one for which Chartered Accountants Ireland has advocated, and which we welcome in this Plan." Similarly, Chartered Accountants Ireland in its position paper Achieving Our Climate Goalshas called for the Government to support SMEs to embed sustainability in their operations; therefore, we welcome the Action Plan’s emphasis on the importance of independent advice and financial supports for SMEs in order to become more competitive and resilient through decarbonisation, while ensuring that the economic and commercial incentives for all businesses drive decarbonisation and the renewable energy revolution, with resilient employment and indigenous value creation over the medium term. We will continue to monitor the delivery of the elements in the implementation framework of the Plan, and to advocate for the clarity businesses and communities require to see plan translate to action.
