If you have not yet made the booking, make sure on the 'Trip Details' page on Magenta Gold, you select from the 'Residence' drop-down menu, IOM, if available. This will automatically not charge the customer IPT (Insurance Premium Tax) on their policy. See video: http://recordit.co/gic0D49lUM
However, if IOM is not available under the 'Residence' drop-down menu or the customer has already purchased the policy with IPT, please email Insurance Team on insurance.team@holidayextras.com with all the relevant details and they will get this refunded back to the customer.
