Policy paper

Corporation Tax amendments to the corporate interest restriction rules

Published 6 July 2018

Who is likely to be affected

Large businesses within the charge to Corporation Tax that incur net interest expense and other financing costs (within the scope of Corporation Tax) above £2 million per annum.

General description of the measure

This measure makes technical amendments to the Corporate Interest Restriction (CIR) rules to ensure the regime works as intended.

Policy objective

The CIR rules restrict the ability of large businesses to reduce their taxable profits through excessive UK interest expense. They are part of the government’s wider changes to encourage alignment of the location of taxable profits with the location of economic activity, and are consistent with the UK’s more territorial approach to corporate taxation.

Background to the measure

The CIR rules were enacted in Schedule 5 of Finance (No.2) Act 2017. A tax information and impact note for the CIR rules was published on 5 December 2016 which provides further details of the background to the regime.

As a result of further engagement with affected businesses, certain technical amendments to the legislation have been identified that are necessary for the regime to work as intended.

Draft legislation was published for consultation on 6 July 2018.

Further amendments are being made to the CIR rules in response to changes in lease accounting.

Detailed proposal

Operative date

The proposed revisions below are to have effect for periods commencing on or after 1 January 2019, unless otherwise stated.

Current law

The CIR rules are in Part 10 of Taxation (International and Other Provisions) Act 2010.

Proposed revisions

Legislation will be introduced in Finance Bill 2018-19 to make technical amendments to ensure the rules operate as intended:

• the calculation of adjusted net group-interest expense will be amended to ensure that it deals correctly with capitalised interest and that debt releases with a connected company outside of the group do not distort the calculation (sections 413 and 423)
• the calculation of group-EBITDA will be amended to ensure that, when an alternative calculation election has been made, the calculation is aligned with the normal UK tax rules on unpaid employee remuneration (new section 424A)
• the interest allowance (non-consolidated investment) election will be amended to ensure that any additional amounts of adjusted net group-interest expense and qualifying net group-interest expense as a result of this election are included as part of a single calculation in section 413(1) or section 414(1), with section 413(2) or section 414(2) then applying to the resulting amount (section 427)
• the public infrastructure rules will be amended to ensure that a company can still have access to these rules if it holds a pension fund asset and/or deferred tax asset (section 433) – this will be treated as always having effect
• the public infrastructure rules will also be amended to ensure that where a company is reimbursed for certain variable operating costs incurred under a contract with a public body this do not affect the highly predictable nature of the company’s income and the company can still access the grandfathering rules (section 439) – this will be treated as always having effect
• the rules which deal with the CIR treatment for Real Estate Investment Trusts (REITs) will be amended to ensure that REITs are within the scope of the rules as intended and that they do not effectively suffer a double restriction where the financing-cost ratio test at section 543 of Corporation Tax Act 2010 results in ‘the excess’ being charged to Corporation Tax (section 452) – the second element of this will be treated as always having effect
• the administrative rules will be amended to extend the time limit groups have to appoint a reporting company or to revoke such an appointment (paragraphs 1, 2 and 7 of Schedule 7A) - this will have effect from Royal Assent
• the administrative rules will also be amended to ensure that HMRC can specify other information, as may be reasonably required, to be included in returns (paragraph 20 of Schedule 7A) - this will have effect for returns submitted on or after 1 April 2019
