High Interest Cash ISAs

A high interest cash ISA is a simple way get a good return on your money through tax-free interest, particularly if you're a novice when it comes to choosing savings accounts. You can choose from instant access cash ISAs - which allow you to get hold of your savings at short notice, but tend to pay a lower rate of interest as a consequence - or fixed rate cash ISAs, which can offer a better rate of return in exchange for locking your cash away for a set period of time.

Benefits of a high interest cash ISA include:

  • Tax-free status means you won't be asked to pay any tax on the interest you earn from the cash in your ISA.
  • There is no need to declare your income from a cash ISA on your tax return.
  • Straightforward transfers - you can transfer your cash ISA to a different provider to get a better rate of interest.

Compare the best high interest cash ISAs

There are several factors to consider when choosing a high interest cash ISA:

  • Do you want easy access to your money? An instant access ISA might be the right choice for you, as long as you're willing to accept a slightly lower rate of interest.
  • Are you happy to lock away cash for a set period of time? Fixed-rate cash ISAs might be a better option as they have the potential to offer a greater return long-term.
  • Do you have a lump sum to invest, or are you planning to make small regular payments? Different ISA providers offer different minimum deposits ranging from just one pound to several thousand pounds.
