Guide to ISAs

Grow your money tax-efficiently 

Find out everything you need to know about our ISAs and which ones are right for you.

What is an ISA?

An Individual Savings Account (ISA) lets you save or invest money in a tax-efficient way.

You can grow your savings in a cash ISA, and the interest you earn won’t count towards your Personal Savings Allowance (PSA), so you won’t pay any tax on it.

Investing money into our award-winning Investment ISA (also known as a Stocks & Shares ISA) means any returns you make won’t be liable to UK income tax, tax on dividends or Capital Gains Tax.

What is an ISA allowance?

It’s the amount you can pay into your ISAs each tax year, without paying tax on the money they make. The tax year runs from 6 April to 5 April the following year. The government sets the maximum ISA allowance – it’s £20,000 for this tax year.

You can use your allowance to pay up to £20,000 into an ISA. Or, you can split it across different ISAs, as long as you don’t pay in more than £20,000 across them all in the tax year.

Keep in mind that this allowance could change in the future, so it’s a good idea to use as much of it as you can now.

Our ISAs

Cash ISAs 

Grow your cash savings with tax-free(1) interest with our Instant Cash ISA, Reward ISA and flexible cash ISAs.

Investment ISA 

Start investing from as little as £50 with our low-cost Investment ISA and watch your money grow tax-free over time.

Terms, conditions and ISA rules apply.

The value of investments can fall as well as rise so you may get back less than you invest. Tax rules can change and their effects vary depending on your individual circumstances.

Can I open an ISA?

You can open an ISA if you’re:

  • 18 years old or over
  • A UK resident.

Crown employees, and members of the armed forces based overseas and their spouses, can also open an ISA.

ISA FAQs 

Putting money in an ISA helps protect the interest or returns you make from tax. It’s good to consider this along with what interest rate you want to earn and how often you need to take money out.

The ISA allowance is the amount you can add to your ISAs each tax year.

You can use the full £20,000 annual ISA allowance to pay into an ISA. Or, you can split the allowance across different ISAs (subject to individual account limits) as long as you don’t pay in more than £20,000 across all of them. Any money you pay into your ISAs will count towards your overall annual ISA allowance. 

If you don’t use your allowance, you’ll miss out on protecting any interest or returns from tax that tax year. Any allowance you don’t use will be lost because it won’t carry forward into another tax year. 

Your Personal Savings Allowance (PSA) is the total amount of interest you can earn each tax year across all your accounts (except ISAs), with any bank or building society, without paying tax. The tax year runs from 6 April to 5 April the following year. Any interest earned on a cash ISA, or returns from an Investment ISA, won’t impact your PSA.

For basic-rate taxpayers, the PSA is £1,000 and for higher-rate taxpayers, it’s £500. Additional rate taxpayers don’t have a PSA.

You’ll need to start paying tax on any interest you earn above your PSA. Go to HMRC’s site to find out how to do this.

Following a change to the ISA rules on 6 April 2024, you can now open and pay into more than one cash or Investment ISA in the same tax year.

However, you can only open and pay into one cash ISA you have with us each tax year right now. You can still open and pay into ISAs with different providers, as long as you don't pay in more than £20,000 across all the ISAs you have.

Yes, you can transfer balances between ISAs using our ISA transfer-in service to make sure you keep earning tax-free interest and your ISA allowance isn’t affected.

You can transfer between our Instant Cash ISAs, Reward ISAs and Investment ISAs at any time. With flexible cash ISAs, you’ll need to transfer within the first 30 days of opening the ISA.

Complete the ISA transfer form in the Barclays app(2) or Online Banking(3) to do this. Alternatively, you can call us or visit a branch. 

The interest you earn on money in a cash ISA will be tax-free for the life of the ISA, providing all ISA conditions are met. The interest rate might change, but the interest paid willl still be tax-free. Keep in mind that ISA rules could change in the future.

As long as you transfer your ISA using our ISA transfer service, it won’t count towards your current tax year allowance. You can transfer previous years’ ISA savings into a new cash or investment ISA and it won’t count towards the current year’s allowance.

For example, if you have £18,000 in previous ISAs, you can transfer some or all of this balance into your new ISA and still have your £20,000 allowance for the current tax year. The interest on the combined balance will also be tax-free. Remember to complete the ISA transfer form in the app or Online Banking. Alternatively, you can call us or visit one of our branches.

Investment ISAs can be invested in UK and overseas shares, bonds, funds, Exchange Traded Funds (ETFs) and investment trusts.
