Withdrawals from your account can be re-deposited during the same tax year without counting towards your annual ISA subscription limits. Interest paid out to another account during the tax year is classed as a withdrawal and can be re-deposited during the same tax year without it counting towards the subscription limit. Withdrawals are deemed to be firstly of current years subscriptions, and secondly of previous years funds. Replacement deposits are deemed to be firstly of previous years funds and secondly of current year subscriptions.

You may transfer your current year’s Cash ISA subscriptions in whole to another Cash ISA with another ISA manager. The transfer must be the whole amount saved in your Cash ISA, in that tax year, up to the day of the transfer.

Where you transfer your current year subscriptions from one type of ISA to another the subscriptions are treated as if they were made to the receiving ISA manager. For example, if your current year’s Cash ISA subscriptions are transferred to a stocks and shares ISA, they are treated as if they were made to the stocks and shares ISA so you are able to subscribe to a Cash ISA following the transfer – subject to the annual subscription limit.

You may transfer any previous tax year’s subscriptions in whole or in part to a Cash ISA or another type of ISA held with another ISA manager, without it affecting your annual ISA investment allowance for the current tax year.
