References to obsolete section 959Z(5)-(8) inclusive have been removed from the guidance.

The purpose of the review is to understand how complaints are experienced in practice, identify systemic issues within the current operating model, and inform options for improvement. The focus is therefore on process and system design hence the review will not examine individual cases.As part of this work, it is important that HMRC hears directly from agents who regularly interact with the complaints process on behalf of their clients. Agent insight is critical to understanding how HMRC complaints handling works in reality, where it creates friction, and where it may not be delivering the intended outcomes for customers.HMRC is seeking to engage with a small number of agent volunteers who would be willing to share their professional experience of HMRC complaints processes, including:How agents and taxpayers experience the complaints journey in practice,Common challenges, delays, or points of confusion when raising or progressing complaints,Issues relating to consistency, ownership, communication, or escalation,The impact of current complaints processes on agents’ ability to support their clients effectively, andAny observations on what works well, as well as where improvement would make the greatest difference.HMRC can either have a short discussion session directly with agents or agents can also provide feedback in writing. Agents are not being asked to share sensitive personal data or client‑identifiable information. All contributions will be considered as provided in confidence and will be used in a thematic and anonymised way only. Contact tax@charteredaccountants.ie as soon as possible should you wish to participate.

Today we issue a final reminder that the deadline for employers to provide employees with their P60 for 2025/26, either on paper or electronically, is Sunday 31 May 2026. The P60 summarises the employee’s total pay and deductions for the year. By this date, employers must give a P60 to all employees on payroll who were working for them on the last day of the tax year (5 April 2026). If an employer is exempt from filing payroll online, copies of P60s can be ordered from HMRC.  

In a speech to the House of Commons last week, the Chancellor of the Exchequer Rachel Reeves announced the UK Government’s long awaited economic response to the war in Iran which includes a range of temporary supports to help families and businesses with the cost of living. The speech included the announcement of the following tax measures:a UK wide scheme will run from 25 June 2026 to 1 September 2026 which will include targeted cuts to agri-food tariffs and a temporary cut in the rate of VAT on summer attractions from 20 percent to 5 percent over the summer holidays,the 5p fuel duty cut is being extended until 31 December 2026. Therefore the planned increases announced in last Autumn’s budget that were scheduled to take place on 1 September and 1 December 2026 will no longer go ahead. The main rate of fuel duty will remain at 52.95p per litre, the duty rate on red diesel will be cut from 10.18p per litre to 6.48p per litre from 15 June until 31 December 2026,over the next 12 months, when hauliers renew their Heavy Goods Vehicle vehicle excise duty, they will pay £1 only, and increases are being made to Approved Mileage Allowance Payments, Mileage Allowance Relief and self-employed mileage. These are being backdated to 6 April 2026. The Government also published a policy paper last week making changes to the taxation of UK tax resident companies who conduct part of their business through foreign permanent establishments (PE).For most companies, it will be mandatory for profits and losses attributable to a foreign PE to be exempt from UK tax for accounting periods beginning on or after 1 January 2027. For those companies conducting oil and gas extraction and exploration through foreign PEs, this measure will apply from 1 September 2026.The changes essentially will make the existing foreign branch exemption election mandatory and whilst this will be of benefit to, for example, companies with profitable Irish PEs, those with Irish loss-making PEs who have not elected will lose the additional corporation tax benefit provided by these losses against their UK profits.

The capital gains tax (CGT) guidance on the requests for clearance on the disposal of land and buildings by non-residents has recently been updated by Revenue, adding additional clarifications and the removal of the words ‘specified assets’ from the guidance title.The guidance now clarifies that a clearance request must be submitted in circumstances where the property had been rented during the period of ownership, notwithstanding that no chargeable gain arises. In cases where there is not a requirement to submit a clearance request to Revenue, the vendor is required to provide the solicitor with written confirmation that the property has not been rented during the period of ownership. Section 2.2.1 has been updated to reflect section 1042(1) TCA 1997, which provides that a non-resident individual disposing of specified assets is liable to pay a capital gains tax liability by the later of three months after the date of disposal, or two months after the date the assessment issues. Section 959AE(1) sets out the circumstances in which Revenue can make an assessment before the return filing date, which includes cases where tax is due on the disposal of specified assets by a non-resident vendor.

The Financial Reporting Council (FRC) has concluded its annual review of FRS 101 and has issued ’Amendments to FRS 101 Reduced Disclosure Framework – 2025/26 cycle’FRS 101 sets out an optional reduced disclosure framework that is available for the individual financial statements of subsidiaries and ultimate parents that otherwise apply the recognition, measurement and disclosure requirements of adopted IFRS. The standard is intended to enable cost effective financial reporting within groups to reduce reporting burdens, particularly for those applying IFRS Accounting Standards in their consolidated financial statements. Each year, the FRC carry out a review of the standard to decide whether FRS 101 should provide exemptions from new IFRS disclosure requirements or whether other consequential amendments are required.In this review, the FRC decided that no amendments were necessary in respect of the new IASB pronouncements Contracts Referencing Nature-dependent Electricity—Amendments to IFRS 9 and IFRS 7 and Amendments to IFRS 19 Subsidiaries without Public Accountability: Disclosures. The Basis for Conclusions has been updated to explain this.In addition, some minor drafting improvements have also been made to the standard.In 2025, Chartered Accountants Ireland responded to the FRC’s exposure Draft “FRED 88 FRS 101 Reduced Disclosure Framework- 2025/26 cycle”, which set out the proposed changes. The institute noted its agreement with these proposed changes.
