It's important to know that if you withdraw money from an ISA, you'll lose the tax benefits on that money.
But, you don't need to keep the money in your ISA with the same manager. You can transfer ISAs to new managers. The rules say that you can transfer some or all of the contents in ISAs from previous tax years but only the total amount you've got in this year's ISA.
Transfers made from one ISA manager to another ISA manager in a tax year will not impact on your annual ISA allowance for that tax year.
For example you could:
- Open one cash ISA to put your 2020/21 allowance into, and open another to move old ISA allowances into
- Or you could open one cash ISA and put your new allowance into it, and transfer old allowances into it too.
Remember to check to make sure that the ISA you open accepts transfers.
