About ISAs

We’ve written a lot of content about ISAs! Here’s everything you need to know to get started.

What is an ISA?

An Individual Savings Account, or ISA, is a kind of savings account.

The big benefit is any returns you make, whether interest, capital gains or dividends, will be tax free.

You can save in to different types of ISA, from Cash through to Stocks & Shares.

ISA allowances

There’s a limit to how much you can save in an ISA each year – set at £20,000 of new deposits.

Though that resets each April, meaning you can keep building up how much you hold in these accounts.

Do you need an ISA?

Just because you can get an ISA, it doesn’t mean you should.

Take a look at whether there are alternative ways to save or invest that might better suit you.

ISA transfers

If you’re moving money between different ISAs, it’s vital you don’t just withdraw the cash.

Instead, you need to follow a process known as a transfer.
