What is the purpose of section 259A of the Taxation (International and Other Provisions) Act 2010?

Section 259A provides an overview of Part 6A, which contains the United Kingdom's hybrid mismatch rules. These rules prevent tax advantages arising where cross-jurisdictional differences in the treatment of entities or instruments cause income to escape tax or expenses to be deducted more than once, by adjusting a person's corporation tax position.

What types of mismatch do the Part 6A hybrid mismatch rules address?

Part 6A addresses two types of mismatch. Deduction/non-inclusion mismatches arise when a tax deduction is claimed but no corresponding taxable income arises for the recipient. Double deduction mismatches arise when the same expense is deducted from more than one person's income or against more than one tax.

What arrangements can give rise to hybrid mismatches under Part 6A TIOPA 2010?

Hybrid mismatches arise in connection with financial instruments, repos, stock lending arrangements, hybrid entities treated differently across jurisdictions, companies with permanent establishments in other territories, and dual resident companies. Chapters 3 to 10 of Part 6A each target specific categories of these arrangements.

How do the hybrid mismatch rules counteract mismatches and in what order do the chapters apply?

The rules counteract mismatches by denying tax deductions or requiring income recognition for corporation tax purposes. Chapters 3 to 10 apply in a specific priority order — Chapter 4 first, then Chapters 3, 5, 6, 7, 8, 9 and finally 10 — with earlier adjustments and equivalent foreign rules disregarded when testing later chapters.

Overview of Part 6A – hybrid and other mismatches

Section 259A provides an overview of the hybrid mismatch rules in Part 6A, which are designed to prevent tax advantages arising where differences in how entities or instruments are treated across jurisdictions lead to income escaping tax or expenses being deducted more than once.

The rules target two types of mismatch: deduction/non-inclusion mismatches (where a tax deduction arises without corresponding taxable income) and double deduction mismatches (where the same expense is deducted more than once or against more than one tax)
The mismatches addressed involve financial instruments, repos and stock lending arrangements, hybrid entities, companies with permanent establishments, and dual resident companies
Counteraction is achieved by adjusting the relevant person's corporation tax position — typically by denying the deduction or requiring income to be recognised
The rules operate in a specific priority order (Chapters 4, 3, 5, 6, 7, 8, 9, then 10), and each chapter's mismatch calculations disregard adjustments made under earlier chapters and equivalent foreign rules
