Budget 2008 - The Remittance Basis - Offshore Mortgages
It was previously announced that paying interest out of foreign income would be treated as a remittance with effect from 6 April 2008. Today’s Budget has relaxed this proposal in respect of existing mortgages.
Interest payments on existing mortgages, which are secured on a residential property in the UK, that are funded out of untaxed foreign income will not now be treated as a remittance. This will continue for the remaining period of the loan, or until 5 April 2028 whichever is shorter. If the terms of the loan or further advances are made after 12 March 2008 the grandfathering provisions will stop.
