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.

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.

How much can I pay into an ISA?

21st March 2019

Each tax year, there's a limit set by the government to the amount you can save and invest in ISAs: your “annual ISA allowance”. The allowances are intended to reward savers and encourage us to invest more to support our future retirements, without creating a tax haven that can be taken advantage of by very wealthy individuals who just want to avoid paying tax.
