The maximum balance is £20,000 for 2017/18 ISA allowance plus previous years’ ISA transfers. Please check with your existing provider if any charges are applicable on transfer.
Deposits for the current tax year’s ISA allowance can be made at any time. External transfers for any used ISA allowances, including both previous years’ and current years’ subscriptions are permitted.
Transferring your ISA
You can transfer some or all of your money saved in previous tax years into a Cash ISA and/or Stocks & Shares ISA and/or Innovative Finance ISA and/or Lifetime ISA without affecting your annual allowance, subject to the product terms of your account. During the 2017/18 tax year only, those who already have a Help to Buy: ISA and held money in that account before 6 April 2017 will be able to transfer this money into a Lifetime ISA without affecting the Lifetime ISA annual contribution limit of £4,000.
You can also transfer money saved in a Cash ISA for the current tax year into a different ISA with the same or a different provider, although you can only hold one of each type of ISA for each tax year. You must transfer the whole amount saved in the current tax year. During the 2017/18 tax year only, money paid into a Help to Buy: ISA on or after 6 April 2017 can be transferred into a Lifetime ISA and will count against the annual contribution limit of £4,000. Transfer charges may apply, please check with your existing provider. Do not transfer any ISA balance yourself otherwise you’ll lose your tax benefits.
