INTM563010 - Thin capitalisation: FA2004 legislation - new rules on loan guarantees

Loan guarantees

As explained in INTM547020, thin capitalisation may be the result of a series of transactions rather than a straightforward loan between two companies. The simplest form of this is where one company provides a guarantee in respect of a loan to another company which has the effect of increasing the amount that could be borrowed by that company. This situation commonly arises where a third party bank makes a loan to a subsidiary on the strength of a guarantee from the group parent and/or fellow subsidiaries, although it can arise where the lender is in the same group as the borrower. Where the result of a guarantee is to increase the interest deductions to the borrower beyond what they would be if that company were borrowing as a wholly independent entity, the provisions of ICTA88/SCH28AA/PARA1B apply to restrict interest deductions on any interest due on or after 1 April 2004 to the arm’s length amount.

ICTA88/SCH28AA/PARA1B for the most part replicates the main thin capitalisation provisions contained in paragraph 1A ( INTM562000). It applies where the provision of a security is made by way of a series of transactions and there is a guarantee provided by a connected company.

Where this is the case it is necessary to overlook the effect of the guarantee from a connected company when deciding how much the borrower could borrow, including the question as to whether there would have been a loan at all at arm’s length. If the effect of the guarantee is to increase the interest deductible in arriving at the assessable profits or allowable losses of the borrower, it is necessary to make an adjustment under SCH2AA/PARA1 to restrict the interest deductible by the borrower to the arm’s length amount.

The term “guarantee” is defined very widely in paragraph 1A(7) and includes any case where the lender has a reasonable expectation that he will be paid by, or out of the assets of, another connected company. This encompasses all forms of written and unwritten guarantee and charges over assets. It also encompasses any informal understanding that has the effect of increasing the borrower’s debt capacity beyond what it would be as a stand-alone entity separate from its parent group.

The term does not however include:

  • any assets of the borrowing company itself
  • any assets of the borrowing company that gives it a right to income from other group companies, such as a loan contract, shareholding or any trade contract
  • any charge that the borrower may have taken in respect of on-lending (see conduit finance at INTM567000).

There is however the possibility of a compensating adjustment for a UK guarantor (see INTM563020).
