UK Corporate Finance Tax in 2026: What the 11th Edition Adds
Two developments are reshaping UK corporate finance tax this year. Since 1 January 2026 the UK has applied the OECD's Cryptoasset Reporting Framework, with providers' first reports due to HMRC by 31 May 2027. And Finance Act 2026 changed how groups appoint a reporting company under the corporate interest restriction (CIR), for periods of account ending on or after 31 March 2026. Tax counsel, treasury teams and finance directors are absorbing both at once.
What the 11th edition brings
David Southern KC's Taxation of Corporate Finance, the relaunched title of Taxation of Loan Relationships and Derivative Contracts, updates the commentary for the Finance Acts 2021 to 2026. It adds a section on crypto-assets, a section on gilts that includes liability driven investment (LDI), an expanded chapter on Islamic finance, and new chapters on the company law framework and the legal documentation of debt. The author is a barrister at Field Court Tax Chambers who specialises in commercial tax.
Where it helps in practice
- Debt and hedging: separate chapters on loan relationships and derivatives, embedded derivatives, foreign exchange, and hedging and deferral support the review of financing and hedging arrangements.
- Interest deductibility: a dedicated chapter on the corporate interest restriction, alongside chapters on the BEPS Project and transfer pricing, helps groups that fund across borders.
- Newer asset classes: the crypto-assets chapter and the gilts and LDI coverage address instruments that now sit on many corporate balance sheets.
