ISAs: Cash ISA versus Stocks & Shares ISA


Stocks & Shares ISAs are becoming more popular as people increasingly ditch their cash holdings as returns from the banks are so minimal. It is not a good idea to ditch cash altogether – everyone needs some easy access to emergency funds – but if you are holding most of your savings in cash ISAs you are missing a trick.

An ISA is an ‘individual savings account’ – a type of wrapper that allows you to take advantage of tax breaks while you save or invest. There are different ISA options available and finding the best one for you is important. Your goals, budget, risk tolerance and capacity for loss are all important factors when considering your best ISA option and should be discussed with a financial adviser.

You have a £20,000 allowance that can be spread over a number of different ISA vehicles.

A Stocks & Shares ISA might be preferable if:

  • you already have an emergency fund
  • you have long-term goals and can wait for results
  • you won’t need to access your money for at least three years
  • you are willing to accept short-term losses for the chance of greater long-term growth

 To help you here is a basic comparison:
