What is the ISA Allowance?
The ISA allowance is the amount of money you can pay into Individual Savings Accounts (ISAs) each tax year while benefiting from their tax-efficient status. For the 2026/27 tax year, the overall ISA allowance is £20,000 per person*.
Any interest, investment income or capital growth earned within an ISA is free from UK Income Tax and Capital Gains Tax, subject to the applicable rules. This makes ISAs an attractive option for people looking to build their savings or invest for the future while making the most of available tax benefits.
Your annual allowance can be divided between different types of ISA, depending on your needs and eligibility, provided you stay within the overall limit and any relevant account-specific rules.
*Tax treatment depends on individual circumstances and tax rules may change in the future
Understanding the different types of ISA
There are several types of ISA available, each designed to support different financial goals. Understanding how they work can help you decide which options may be suitable for you.
| ISA type | What is it for? | Key allowance or limit |
|---|---|---|
| Cash ISA | Saving money and earning tax-free interest | Part of your £20,000 annual ISA allowance |
| Stocks and Shares ISA | Investing for potential long-term growth | Part of your £20,000 annual ISA allowance |
| Lifetime ISA | Saving towards your first home or later life | Up to £4,000 per tax year, within the overall ISA allowance |
| Innovative Finance ISA | Investing through eligible peer-to-peer lending arrangements | Part of your £20,000 annual ISA allowance |
| ISA type | Cash ISA | Stocks and Shares ISA | Lifetime ISA | Innovative Finance ISA |
|---|---|---|---|---|
| What is it for? | Saving money and earning tax-free interest | Investing for potential long-term growth | Saving towards your first home or later life | Investing through eligible peer-to-peer lending arrangements |
| Key allowance or limit | Part of your £20,000 annual ISA allowance | Part of your £20,000 annual ISA allowance | Up to £4,000 per tax year, within the overall ISA allowance | Part of your £20,000 annual ISA allowance |
The UK tax year runs from 6 April to 5 April, and your ISA allowance resets at the beginning of each new tax year. It is important to remember that the allowance is generally a use-it-or-lose-it opportunity. If you do not use your full allowance before the end of the tax year, any unused amount cannot normally be carried forward.
Planning how and when to use your allowance can therefore help you make the most of the opportunities available to you.
How could you use your ISA Allowance?
You do not have to put your entire allowance into one type of ISA. Depending on your circumstances and eligibility, you can divide it between different types to suit your savings and investment goals, provided you stay within the relevant limits.
For example, someone with the full £20,000 allowance available might choose to divide their contributions as follows:
| Example allocation | Amount |
|---|---|
| Cash ISA | £5000 |
| Stocks and Shares ISA | £11,000 |
| Lifetime ISA | £4,000 |
| Total paid in | £20,000 |
| Example allocation | Cash ISA | Stocks and Shares ISA | Lifetime ISA | Total paid in |
|---|---|---|---|---|
| Amount | £5000 | £11,000 | £4,000 | £20,000 |
This example illustrates how you could spread your allowance across different ISA types. The £4,000 Lifetime ISA contribution counts towards the overall £20,000 annual limit rather than being an additional allowance. A Lifetime ISA is subject to specific eligibility criteria and withdrawal rules, so it is important to understand these before contributing.
You do not necessarily need to use your entire allowance every year. The right approach will depend on your income, existing savings, financial commitments and other priorities. It is also important to ensure that you have sufficient accessible savings for emergencies and that any investments you make are appropriate for your circumstances.
How can advice help you make the most of your ISA Allowance?
Making the most of your ISA allowance is not simply about paying in as much as possible. It is about understanding how the allowance fits with your financial circumstances, your future plans and the level of access or investment risk that is right for you.
For some people, a Cash ISA may be suitable for short-term savings or those who prefer to keep their money in cash. For others, a Stocks and Shares ISA may be worth considering if they are investing for the longer term and are comfortable with the risks involved. If you are eligible, a Lifetime ISA may also help you save towards your first home or retirement.
