How much can I pay into a cash ISA?

You can pay up to £20,000 into ISAs in each tax year, and this allowance can be used entirely in a cash ISA if you wish, or split across different types of ISA.

The big advantage of a cash ISA is that all the interest you earn is completely tax free, which can be especially valuable if your savings interest would otherwise exceed your Personal Savings Allowance.

Can I transfer an existing ISA without losing the tax benefits?

Yes, you can move money between ISAs using the official ISA transfer process, which keeps your savings within the tax-free wrapper so you do not lose any of the benefits.

The key is to ask your new provider to arrange the transfer rather than withdrawing the money yourself, as taking it out directly would mean it loses its ISA status.
