This case concerned deductibility of notional interest paid in 2003-7 by two permanent establishments in the UK to their Irish HQs. The loans – and thus interest expenses – had been allocated to the PEs as if they were separate entities. The UK tax authorities held that interest deductibility was restricted by UK tax law, which prescribed that PE’s has such equity and loan capital as it could reasonably be expected to have as a separate entity. The UK taxpayers, refered to  Article 8 of the UK-Ireland tax treaty.

For the tax years 1981-1987, NatWest conducted wholesale banking operations in the United States through six permanently established branch locations (collectively “the U.S. Branch”). On its United States federal income tax returns for the years at issue, NatWest claimed deductions for accrued interest expenses as recorded on the books of the U.S. Branch.
