An ISA (Individual Savings Account) is a tax-efficient way to invest and forms an important part of any financial plan.
Cash ISAs are similar to standard savings accounts, but the interest you earn is tax-free. The alternative of a Stocks & Shares ISA allows you to put your money into a range of investments. This gives you the potential for greater rewards, but comes with additional risk which needs to be considered.
With all ISAs there is a limit on how much you can invest each year.
