The IFISA allows individuals to use part, or all, of their annual ISA allowance to lend funds through marketplace lending platforms. Marketplace lending allows individuals to lend directly to borrowers via an online platform. You are only permitted to open one of each type of ISA per tax year (i.e. one Innovative Finance ISA, one stocks and shares and one cash). Please see ‘How many ISAs can I open in each tax year?‘ for more information.
