Many businesses have positively adapted and innovated as a consequence of COVID-19, whilst some others are continuing to find it hard, owing to the nature of their business or the industry in which they operate.

As a consequence, we are increasingly receiving queries from clients who would like to understand what the consequences may be if they inject more debt financing into their business or change some of their existing borrowing arrangements.

Below we set out some of the common points worth bearing in mind when considering the impact of changes to funding or interest arrangements.

Corporate interest restriction 

For corporate businesses, the Corporate Interest Restriction (CIR) limits the amount of interest expense which the business is able to deduct when computing its taxable profits to 30% of UK taxable profits. This restriction applies if the company or group’s total UK net tax interest expense is greater than the £2 million de minimis amount.

The actual rules surrounding the calculation of the interest restriction are detailed and complex, although some of the key points to consider are:

  • the term ‘interest expense’ includes a wide range of items including loan interest expenses, some derivative contract expenses and the finance cost element of arranging some loans, finance leasing or debt factoring transactions
  • the rules work on a group basis rather than a company by company basis and therefore most calculations are carried out looking at the overall group position, with restrictions then being pushed down to individual companies as appropriate
  • the group referred to in the rules is the ‘worldwide group’ and broadly covers the ultimate parent entity and each of its consolidated subsidiaries
  • the CIR rules apply after other potential restrictions on interest deductibility are applied, such as transfer pricing adjustments, late payment rules, the anti-hybrid rules and the unallowable purpose rules
  • for a net interest expense in excess of £2 million the basic tax deductible interest amount is based on 30% of UK taxable profits (tax-EBITDA). Although there are other calculations and adjustments that need to be considered before being able to conclude on the final interest allowable amount
  • where an interest restriction occurs a separate interest restriction return needs to be filed with HMRC
  • disallowed interest amounts can be carried forward to be used in future periods where there is sufficient interest capacity
  • from 6 April 2020, the CIR rules apply to non-UK resident companies that have a UK property business or other UK property income.

With many companies currently taking on more debt to expand, restructure and innovate and with interest on CBILS loans now needing to be paid, it will be important for business owners to understand whether all of the associated interest will be tax deductible for corporation tax. To the extent that the group’s total UK net tax interest expense is greater than £2 million then full relief may not be given.

Late paid and rolled up interest

Interest paid between one corporate business and another is generally treated as ‘paid’ for corporate tax purposes at the time it is accrued in the accounts.  

However, in some circumstances, for example where the interest is paid to a non-corporate, like to an individual or partnership, or the debtor is a close company and the creditor is a participator in a close company, then the late payment interest rules need to be taken into account.

Under these rules if the interest is rolled up and accrued, but not paid within 12 months of the accounting period end, then a corporate tax deduction can only be taken in the year in which the interest is paid.  This can lead to an unexpected tax charge for those that are not familiar with this rule.

A further issue can arise if the late paid interest is paid all in one go at some point in the future. As tax relief may not be available in full if the interest expense at that time exceeds the £2 million de minimis and 30% of UK tax-EBITDA under the CIR rules noted above.

Lastly, for groups that are sold, care needs to be taken as to when any rolled up interest is paid, as the sale of a whole group can cause the group’s original CIR group to end at that time. If the rolled up interest is then paid post sale, any brought forward interest allowance under the CIR rules may not be able to be used. Instead the interest expense will form part of  the new group’s CIR calculation which can lead to unintended interest restrictions for the purchaser.

As an alternative to paying the interest, in order to obtain a tax deduction under the late payment rules, it is also possible for the borrower to issue Payment in Kind notes (PIK notes) to the lender. These may be used, for example, in private equity financing arrangements. The PIK notes are treated for tax purposes as representing interest paid, although they are in fact further loans which themselves bear interest.

Thin capitalisation and transfer pricing

The UK has a transfer pricing regime under which it is a group/company’s responsibility to ensure that transactions between connected parties are undertaken on an arm’s length basis. To the extent that a transaction between associated persons has not taken place on an arm’s length basis, then the UK transfer pricing rules require an appropriate profit adjustment to be made.

In the UK there are exemptions from the UK transfer pricing rules for small and medium enterprises (SME’s).

The UK’s transfer pricing rules apply to all types of transactions including financing transactions. In addition, for financing transactions, it is important that companies are not considered to be thinly capitalised taking into account the level of debt versus equity. Broadly, this is to ensure that the quantum of the loan amount and the interest rate charged are similar to those that would apply on an arm’s length transaction.

When assessing whether the interest rate is similar to a third party arm’s length rate all aspects of the funding cost should be taken into account including any commitment fees, arrangement fees, guarantee or other costs. To the extent that the interest charged is higher than that which would be charged by a third party on a commercially acceptable size loan, the borrower must make a tax adjustment to disallow the excess interest amount. To the extent there is an adjustment required the lender may, depending on the facts, be able to claim a compensating adjustment.

With more businesses seeking funding at the current time, both from third party sources and also from private equity or connected inter-group lending, we are seeing transfer pricing become more topical for UK businesses.

Withholding tax

If a UK company pays interest to another UK company then withholding tax is not required to be withheld.  

Although in other instances, where yearly interest is paid – broadly interest paid on loans capable of lasting more than 12 months, withholding tax may need to be applied at the rate of 20%.

Examples would include interest paid to individuals, partnerships, overseas companies or other hybrid entities. Where withholding tax is required to be applied then this should be withheld and paid over to HMRC on a quarterly basis using form CT61.

Where withholding tax is required to be applied then this should be withheld and paid over to HMRC on a quarterly basis using form CT61.

The recipient of the interest can then usually claim relief from the withholding tax suffered from their UK or overseas tax liability.

Withholding tax should be borne in mind, particularly in relation to shareholder loans from individuals, as the deduction of 20% tax can be an unwelcome surprise and create a cashflow issue for some investors.

Debt releases

Debt restructuring is becoming more common as businesses look at ways in which they can restructure their existing financing arrangements to change the level of debt or manage their future interest obligations.

As a general rule, where a company releases a debt and for the borrower there is a corresponding credit to profit and loss account this is taxable.

However, in some situations a tax free debt release is possible.  The main situations where this can arise are:

  • release of a connected company debt
  • where a loan is released and falls within the parameters of the UK’s corporate rescue exemption
  • there is a qualifying debt for equity swap which falls within the debt for equity swap exemption.

All of the above come with a number of tax rules which should to be considered. Whether a tax free debt release arises will turn on the individual facts in each case. It is therefore highly recommended that tax advice is sought in advance of any restructuring or debt being released. 

Summary

In the current environment many businesses are considering their funding options and refinancing as part of the wider package of measures to be able to  innovate, adapt and prosper.

As noted above, there are various considerations that need to be borne in mind when considering such options to ensure that there are no unwelcome surprises, including:

  • additional costs
  • tax reliefs that are not available or are delayed
  • tax charges that crystallise.

In many cases, with appropriate upfront planning, a number of the above issues can be mitigated or at worst they can be planned for as part of any wider strategic and business planning process.
