    The Nucleus Jisa has access to the model portfolio functionality

    The tax treatment of an investment or savings product depends on the individual circumstances of each client and may be subject to change in future.

    Past performance is not a reliable guide to future performance, nor a reliable indicator of future results or performance. The value of an investment can go down as well as up, and may be less than the amount(s) paid in.

    What else does it offer?

    Payments can be made flexibly through single or regular payments

    Regular payments can be increased, reduced, started or stopped at any time

    We accept re-registrations and transfers from CTFs or existing Jisas without charge

    Your clients can choose from over 6,000 assets


    A child is eligible to open a Jisa if they’re resident in the UK and under the age of 18 and don’t have a Child Trust Fund (or if they’re transferring a CTF into the Jisa). A child under 16 can’t complete a Jisa application themselves. Only a person with parental responsibility can complete the application.

    Subscription limits

    The overall Jisa subscription limit is £9.000 for the 2021-22 tax year end. This can be split over a cash Jisa and a stocks and shares Jisa. If the full subscription isn’t used within the tax year, it will be lost. There’s no opportunity to carry it forward, so it’s important to ‘use it or lose it’.

    Registered contact

    A Jisa account must have a registered contact and, most often, this will be the person who completed the Jisa application. There can be only one registered contact for a Jisa at any time and they are the person authorised to give instructions about the management of the account.
