We remind readers that Mandatory Tax Adviser Registration commenced last month from 18 May 2026. HMRC has now published updated guidance to help overseas advisers assess their obligations under this legislation which will be of particular interest to our members in Ireland and overseas who may also be required to register for an agent services account. For both overseas and UK based advisers, the first three-month MTAR window may have commenced from 18 May 2026, unless a later start date applies. HMRC has also published a new MTAR manual.After MTAR launched last month, HMRC began hosting weekly stakeholder drop-in sessions for trusted stakeholders, including Chartered Accountants Ireland. The purpose of these sessions is to establish a regular forum to:share feedback on the new service and user experience,highlight any early operational or technical issues, andraise questions or concerns as they arise.HMRC expects these sessions to support early identification and resolution of issues, and to ensure stakeholder insight is captured as the service embeds. These sessions are attended by HMRC representatives from the policy, project delivery, and IT teams responsible for delivering MTAR. Chartered Accountants Ireland therefore encourages members to share their feedback on MTAR with us so that this can then be discussed with HMRC at these sessions.In addition to HMRC’s guidance pages which we have previously shared, HMRC has published a range of additional MTAR resources. An interactive guidance tool is also available in addition to a useful factsheet covering common questions, including: The transition period,The scope of the registration requirement, andThose within businesses (known as relevant individuals) that need to meet the registration conditions.As a reminder, HMRC is introducing the requirement to register in stages. The current timetable to register is as follows:18 May to 18 August 2026New tax advisers, including overseas advisers who do not currently have an Agent Services Account (ASA), or online Self-Assessment or Corporation Tax account. 18 August to 18 November 2026Tax advisers who have an online Self-Assessment or Corporation Tax account, but no ASA. 18 November 2026 to 18 February 2027Tax advisers who solely provide payroll services and who do not have an ASA. 31 December 2026 to 31 March 2027 Financial services organisations with no ASA (a full definition for this group will be set out in secondary legislation).  Tax adviser businesses have three months from the start of their registration window to apply. During this period, and whilst their application is being considered, they can continue to interact with HMRC on behalf of their clients.Those with an existing ASA do not have to register again with HMRC. HMRC will contact these businesses between January and March 2027 so that checks can be conducted against the new registration requirements. To assist members with meeting their obligations under this legislation, the Institute’s MTAR hub contains a suite of resources to help you determine if you are in scope, when you need to register, and what actions you need to take. Further resources on the various sanctions available to HMRC under this legislation will be added to the hub in the coming months.

Last week Revenue issued a press release announcing changes to EU customs rules for low-value imports (€150 or less) from non‑EU countries, including Great Britain. From 1 July 2026, a €3 customs duty will apply per item within a parcel, increasing the cost of many online purchases and impacting the returns process. Currently, there is no customs duty on low value imports.The €3 customs duty may be applied at checkout or upon delivery, depending on the retailer. Consumers should check sellers’ terms in advance to avoid unexpected charges or delays and be aware that goods may be shipped from outside the EU, even where a website appears Irish or EU‑based. In general, customs duty is non-refundable and if a customer decides to return an item, it is likely that the €3 customs duty will only be refundable in cases where the goods are faulty. Further information and examples, including details on how the charge is applied per item is included on Revenue’s website.

Revenue has updated the examples in the guidance on PAYE reviews where week 53 applies to reflect the 2025 tax credits and cut off points.

Revenue has published two new guidance manuals providing filing information relating to several Pillar Two tax returns. The new guidance on Top-up tax information return and notification of filer provides a user guide for entities required to file a Top-up tax Information Return (TIR). The TIR has been available for filing since the end of April this year. The guidance titled IIR, UTPR and QDTT Returns and Payments provides guidance on the filing and payment obligations and processes for IIR (Income Inclusion Rule), UTPR (Undertaxed Profit Rule) and QDTT (Qualified Domestic Top-up Tax) returns.The Top-up tax information return and notification of filer manual provides guidance on how to file a TIR or a Notification of Filer which is required in cases where the TIR has been filed in another jurisdiction and will be exchanged with Revenue. ROS access and upload instructions, links to the OECD’s detailed guidance and Revenue contact details are also included in the guidance.Relevant ROS access and upload instructions together with other relevant return filing and payment obligations are outlined in the guidance on IIR, UTPR and QDTT Returns and Payments.Prior to filing a return or making a payment, it is recommended that an entity should ensure their relevant Pillar Two registration is correct and up to date. In addition, where the constituent entities of a multinational or large-scale domestic group elect to form a QDTT group or a UTPR group, the members of the group should ensure that a group filer is appointed and that group filer completes the creation of the group on ROS.

The Department of Finance (DFIN) has published the Annual Progress Report (APR) for 2026. The APR is a legal requirement under EU law and is part of the reformed European fiscal architecture. The APR’s main purpose is to assess government expenditure growth against planned expenditure, and to provide an update on the Government’s Medium Term Structural-Fiscal Plans. The APR highlights a resilient macro-fiscal position, but one increasingly exposed to external shocks and structural vulnerabilities including the concentration of corporation tax receipts. The Department of Finance projects GDP growth of 3.1 percent in 2026 and 3.5 percent in 2027, with Modified Domestic Demand (MDD) expanding by a modest 2.1 percent this year as higher energy costs dampen consumption. Inflation has re-emerged as the dominant near-term risk, rising to 3.3 percent in 2026 due to geopolitical-driven energy price shocks, before easing to 2.5 percent in 2027 under baseline assumptions. From a fiscal perspective, Exchequer deficits of €1.2 billion for 2026 and €3.4 billion for 2027 are forecast. However, there is in fact an underlying general annual government surplus of circa €9 billion. The divergence reflects transfers to long-term savings vehicles (Future Ireland Fund and Infrastructure, Climate and Nature Fund), which are neutral on a general government basis but materially impact Exchequer metrics. Total tax receipts are projected at €110.8 billion in 2026 and €116.3 billion in 2027, with corporate tax expected to contribute €35.3 billion and €37.4 billion respectively. Corporate tax continues to account for roughly one-third of revenues, supported partly by global minimum tax reforms. At the same time, the reliance on corporation tax receipts is explicitly flagged in the report, with over half derived from a small cohort of multinationals. Income tax (€38.9 billion) and VAT (€23.6 billion) show steady growth in 2026, while excise receipts decline due to temporary policy measures aimed at cushioning energy costs. Medium-term projections underline a structural issue: despite headline surpluses and declining debt (to 58 percent of GNI* in 2026), the State runs an underlying deficit exceeding €10 billion, once volatile corporate tax receipts are stripped out.  Therefore, the key risks for the Exchequer stem from corporate tax sustainability, energy-driven inflation, and geopolitical fragmentation, alongside emerging tax base implications from AI-driven productivity shifts. Commenting on the publication, Tánaiste and Minister for Finance, Simon Harris said: “The international environment is highly uncertain it is important to be clear about where Ireland stands today. We are entering this period from a position of strength. Our labour market is operating at full employment, domestic demand has continued to expand, and the public finances remain in a relatively healthy position.While risks to the outlook are significantly tilted to the downside, this Government will continue to respond in a way that is decisive and responsible, and in a way that supports the long-term resilience of our economy”
