The general principle applicable is that financial services, as defined by the VAT Law and Executive Regulations, will be subject to VAT at the standard rate when they are supplied for an explicit fee, discount, commission, rebate or similar type of charge.
Financial services, insofar as they are remunerated by way of an implicit margin or spread (i.e. no explicit fee is charged in respect of them) will be exempt from VAT.
