Finance Bill 2026—advance tax certainty service for major projects
Tax analysis: Helen Coward is a partner at Simmons & Simmons LLP. Helen provides both direct and indirect tax advice on a wide range of matters and transactions, with particular experience in relation to real estate taxation, investment funds and private equity transactions. In this article, Helen considers the advance tax certainty service, launching in July 2026, which is a new HMRC initiative offering binding, upfront tax certainty for major UK investment projects. Open to both UK and non-UK investors, the service is open to projects with at least £1bn of qualifying UK expenditure. It covers corporation tax, VAT, Stamp duty land tax (SDLT), income tax, Pay As You Earn (PAYE), and the construction industry scheme. Clearances are binding on HMRC for up to five years, with the possibility of renewal, unless there is a change in law or material facts. The process is intended to be collaborative, involving early engagement and scoping meetings, and aims for a 90-day turnaround once an application has been made. The service is expected to enhance the UK’s attractiveness for large-scale investment, with its scope and operation to be reviewed after 12 months to ensure it meets business needs.
