What is an ISA allowance?
An ISA allowance is the total amount of money you can save or invest across ISAs within one financial year without paying income tax or capital gains tax on any returns or interest.
Your allowances across various investment schemes have the potential to change each year, which is why it’s important to keep up to date with the current year’s allowance.
In the UK, there are four main types of ISA:
- Cash ISAs
- Stocks and shares ISAs
- Innovative finance ISAs
- Lifetime ISAs
You can choose to open ISAs with more than one provider and choose a mixture of ISAs within a tax year, providing you don’t exceed the maximum annual allowance across all the ISAs you hold.
It is important you check your eligibility for each type of ISA, and remember, you can only pay into one Lifetime ISA in a single tax year (up to £4,000).

Stocks and shares ISA rules for 2025/26
For the 2025/26 financial year, you can save or invest up to £20,000 tax-efficiently in your stocks and shares ISA. The UK government review and set the stocks and shares ISA limit every April.
This £20,000 can all be invested in a single ISA, split across more than one ISA with different providers or split between different types of ISA such as a cash ISA or Lifetime ISA. However, you can only pay into one Lifetime ISA in a single tax year (up to £4,000).
Our ISAs offer a great way to invest from £25 a month, with potential for more growth than a cash-based savings account. A stocks and shares ISA invests your money across stocks, shares, equities, bonds, and property.
Junior ISA allowance for 2025/26
A Junior ISA (JISA), or child’s ISA, is a tax-efficient savings or investment account which allows you to give a tax-free lump sum to your child as soon as they turn 18.
The Junior ISA allowance is £9,000 for the current tax year, which is different from adult ISAs. This is the maximum total amount that can be deposited into a Junior ISA before the next tax year (beginning April 6th, 2026).
A child can only hold one stocks and shares Junior ISA each tax year, but they can also hold a cash Junior ISA. The Junior ISA allowance can be spread across both types of plans, if you do not exceed the overall allowance.
How can you use your ISA allowance?
When considering how to best use your ISA allowance, there are two main options:
- You can use your ISA allowance in full for a single ISA, such as a stocks and shares ISA, paying in up to £20,000.
- You can split your ISA allowance across more than one ISA, with different providers, with the rule that you don’t pay in any more than £20,000 across all investments.
Stocks and shares ISAs can include investments in:
- Shares in companies
- Unit trusts and investment funds
- Corporate bonds
- Government bonds
Cash ISAs can include:
- savings in bank and building society accounts
- some National Savings and Investments products
more than the overall limit of £20,000. Otherwise, you may be liable for tax on your returns.
If you want your money to make the most of your new ISA allowance in 2025/26, it’s wise to start investing sooner rather than later. As mentioned, this allowance will only last until April 2026; if you don’t use it, you can’t carry any unused allowance over to the following tax year.
Using your allowance to invest in a stocks and shares ISA
The most important thing to remember about opening a stocks and shares ISA is that it carries a higher risk than a bank or building society cash ISA.
As the fund is invested in stocks and shares, there are inevitably risks associated with the performance of financial markets. Unlike a cash-based savings account, where there is normally a set or guaranteed rate of interest on your savings, the returns for a stocks and shares ISA depends on the financial market, meaning that you may get back less than you put in.
Because of this, a stocks and shares ISA should always be considered a medium to long-term (5 years plus) investment. Making regular withdrawals from your stocks and shares ISA may negatively affect the purchasing value of your investment.
Similarly, if you withdraw from the investment early for any reason, it may mean you get less back than you expected.

FAQs about the Stocks and Shares ISA allowance
When does the ISA allowance renew?
The tax year, set by HM Revenue & Customs, ends at midnight on 5th April each year. This means that you get a new ISA allowance starting on the 6th April each year.
If you are looking to maximise the use of your ISA allowance this financial year, then it is important to remember that the deadline to do so is the 5th April 2026, as allowances do not rollover if you haven’t used it all.
Does the ISA allowance roll over if I don’t use it?
No, it doesn’t. Your ISA allowance renews each year. If you don’t use your full ISA limit before the end of the tax year (which is at midnight on 5th April) then your ISA allowance for the current tax year has gone and can no longer be used.
It’s not possible to roll over any unused allowance. For example, if you save £10,000 into your ISA this tax year, you can’t add £30,000 into your ISA next year within the tax-free limit. Your ISA allowance would remain at £20,000 (unless the Government changed the ISA limit amount).
If I transfer my ISA does it affect my annual allowance?
Transferring your ISA from one ISA provider to another does not affect your annual allowance. You still can save up to the annual limit of £20,000 for this financial year.
You’re free to transfer and split your ISA allowance any way you like across a stocks and shares ISA, cash ISA, Lifetime ISA (maximum of £4,000) and an Innovative Finance ISA, if you stay within the overall limit.
However, there are a couple of stocks and shares isa transfer rules that you need to be aware of.
Be careful when transferring a stocks and shares or cash ISA into a Lifetime ISA. While this won’t affect your overall annual ISA subscription allowance for that tax year, it will count towards your annual Lifetime ISA subscription limit of £4,000.
This also applies to if you are transferring your savings from a previous tax year. This won’t count towards your allowance for the current year.
