What is manufactured interest on UK securities under section 578 of the Income Tax Act 2007?

Manufactured interest is a substitute payment made to compensate the original holder of UK securities, such as gilts or corporate bonds, for interest they miss while their securities are temporarily transferred under a stock lending or repurchase agreement. Section 578 treats this payment as real interest for income tax purposes.

How is the recipient of manufactured interest taxed under section 578?

The recipient of manufactured interest is taxed as if they had received a genuine interest payment on the underlying UK securities. The tax treatment applies to the beneficial owner of the manufactured interest, not necessarily the person who directly receives the payment, ensuring taxation follows economic substance.

Does the tax treatment of manufactured interest change if a nominee receives the payment?

No. Section 578 preserves the treatment as real interest even where manufactured interest passes through a nominee or intermediary who is not themselves subject to income tax. The underlying beneficial owner remains taxable on the manufactured interest as though it were a real interest payment on the UK securities.

Can the payer of manufactured interest claim a tax deduction under the Income Tax Act 2007?

The payer of manufactured interest may be entitled to claim a deduction for the amount paid, but this is not automatic. The availability and conditions for such deductions are governed by sections 579 and 580 of the Income Tax Act 2007, which must be consulted separately to determine eligibility.
