What is an ISA?

An ISA is an Individual Savings Account, that allows you to save or invest money in a tax-efficient way.

How much can you put in an ISA?

If you are over 18 and eligible to subscribe, you can save up to £20,000 this tax year in an ISA without paying UK income tax or capital gains tax on the interest.

The maximum amount you can deposit in an ISA is subject to annual subscription limits. The annual subscription limit for the current tax year is £20,000.

From 6 April 2024, for customers aged 18 and over, ISA regulations allow this to be saved in multiple cash ISAs, multiple stocks and shares ISAs, multiple innovative finance ISAs or up to £4,000 into one lifetime ISA with either the same or different providers in the same tax year.

You don't have to declare interest earned or capital gains on savings, or investments, up to that amount on your tax return, so it's tax free. But keep in mind, these rules may be subject to change in the future.

Types of ISAs

Cash ISAs

Cash ISAs work like other savings accounts, with the added bonus of being tax efficient. You can choose from a:

Interest rates will vary depending on the bank, or building society, you choose.

Stocks & shares ISAs

Stocks & shares ISAs enable you to make investments without having to pay UK income tax, or capital gains tax, on any profits made.

But it’s important to remember the value of investments can fall as well as rise and you may not get back what you invest. They should also be considered a medium to long term commitment, so you should be prepared to hold them for at least 5 years.

Lifetime ISAs

Lifetime ISAs are a type of tax-efficient account that can help you buy your first home or save for later life.

HSBC doesn't currently offer lifetime ISAs.

Innovative finance ISAs

Innovative finance ISAs contain peer-to-peer loans instead of cash, or stocks and shares.

HSBC doesn't currently offer innovative finances ISAs.

How many ISAs can you have?

From 6 April 2024, for customers aged 18 and over, ISA regulations allow you to save in multiple cash ISAs, multiple stocks and shares ISAs, multiple innovative finance ISAs or up to £4,000 into one lifetime ISA with either the same or different providers in the same tax year.

Customers aged 18 or over will only be able to subscribe to one type of cash ISA and one type of stocks and shares ISA in the same tax year with either HSBC or first direct. However, even if you subscribe to an ISA with HSBC (or first direct) you will still be able to subscribe to ISAs with other ISA providers (subject to eligibility and availability).

ISA inheritance

The value of an ISA can be passed on to your spouse, or civil partner, tax-efficiently if you pass away. This isn't the case with an ordinary savings account. For this to take place, the government requires you to:

  • Be living together at the time of death
  • Not be separated by court order, or deed of separation
  • Not be in a circumstance where the marriage, or civil partnership, has broken down1

How are ISAs changing in the 2024 / 2025 tax year?

Cash ISA age limit

From 6 April 2024, there are changes to how old you need to be to open a cash ISA.

To open a new cash ISA, you need to be either:

  • 18 years old or over, or
  • Covered by the transitional arrangements for those aged 16 or 17 (as of 5 April 2024), which is in place until 5 April 2026

ISA providers aren't obliged to offer the transitional arrangements. HSBC won't allow customers under 18 to open a new cash ISA from 6 April 2024 but will consider changing this in the future.

Subscribing to more than one of the same type of ISA

If you're aged 18 or over, you'll now be able to subscribe to more than one of the same type of ISA in the same tax year – subject to staying within the overall annual limit.

For example, you could subscribe to a cash or stocks & shares ISA with one ISA provider and also subscribe to one with a different provider.

This change doesn’t apply to Lifetime ISAs, where it's still only possible to subscribe to one Lifetime ISA in a tax year. HSBC doesn't offer Lifetime ISAs.

From 6 April 2024, ISA providers are not obliged to allow subscriptions to more than one ISA of the same type in the same tax year with themselves, and HSBC will not be offering this.

Other optional changes that not all providers are implementing

If you've gone a whole tax year without making a subscription to an existing ISA, you can now restart subscriptions without needing to complete a new application.

Since 6 April 2024, some providers allow you to make a partial transfer of subscriptions made in the current tax year, but HSBC is not currently allowing this.

We'll update our website if we make any changes to our ISAs in the future.

The value of any tax benefits described depends on your individual circumstances. Tax rules may change in the future.
