Which Is Better – a Cash ISA or a Stocks and Shares ISA?

That depends!

If you are extremely risk averse and don’t have the appetite for dealing with the volatility that stock markets present, then cash ISAs may be right for you.

However, if you are not satisfied with the ISA interest rates that many fixed and variable cash ISA products offer, then stocks and shares ISAs may be what you want.

Note, though, that while cash ISAs generally offer account protection, investing in a stocks and shares ISA may result in you losing some/all of your principal.

Will I Lose the Ability to Access My Money in a Cash ISA?

Not necessarily!

There is a common misconception that money deposited into a cash ISA is untouchable. There are a number of top cash ISAs that allow you easy access to withdraw your money as and when you need it.

Be aware, though, that certain cash ISA allowance rules do apply. For instance, if you invest your entire ISA limit into a cash ISA in the current tax year and then make a withdrawal, you are not allowed to top up the account the same tax year. That’s because you will be deemed as having utilized your cash ISA allowance for 2015–2016 to the maximum allowed.

Here is another FAQ:



Wouldn’t it be simpler to just cash in my ISA and move the money to another institution?

Absolutely not!

Doing so will cause you to lose all of the tax-free benefits that you may have accumulated so far.

Transferring is the best way to move your account from one provider to another while still benefiting from the best ISA rates offered at the receiving institution.

A transfer is easily accomplished by providing your existing provider with the appropriate instructions and filling out a simple form.
