An Individual Savings Account (ISA) is one of the most popular and tax-efficient ways for UK residents to grow their savings. You can put cash aside for short-term goals, build a long-term investment portfolio, or save for your first home, and an ISA allows your money to grow free from UK Income Tax and Capital Gains Tax.
With an annual ISA allowance of £20,000 per person, these accounts can play an important role in a savings and investment strategy. But many people are unsure about how many ISA accounts they can hold, if they can contribute to more than one ISA in the same tax year, and how the annual allowance is applied across different ISA types.
If you’re wondering how many ISAs you can have and how the £20,000 allowance works in practice, here’s everything you need to know.

How many ISAs can I have?
To answer the question, there is no limit to the number of ISA accounts you can hold. You can have multiple Cash ISAs, Stocks and Shares ISAs, Innovative Finance ISAs and Lifetime ISAs with the same or different providers. Since the rules were updated in April 2024, you can also pay into more than one ISA of the same type during the same tax year, provided you stay within your overall annual ISA allowance.
Now, the number of accounts you can hold is unlimited. But the amount you can contribute is not. For the 2026/27 tax year, the total ISA allowance is £20,000 per person. This allowance is shared across all of your ISAs, meaning any money you pay into one account reduces the amount you can contribute to others.
For example, if you put £8,000 into a Cash ISA, you would have £12,000 of your annual allowance remaining to use across other ISAs. Having multiple ISAs can be useful if you want to separate your savings goals, take advantage of different interest rates or combine cash savings with investments.
| ISA Type | Annual contribution limit for 2026/27 |
| Cash ISA, Stocks and Shares ISA, Innovative Finance ISA (IFISA) and total ISA | £20,000 |
| Lifetime ISA (LISA) | £4,000 |
| Junior ISA (JISA) | £9,000 |
The different types of ISA
There are different types of ISAs you can open in 2026
| ISA Type | Characteristics |
| Cash ISA | Typically pays interest on your savings |
| Stocks and Shares ISA | Allows you to invest in equities, funds, bonds, etc |
| Lifetime ISA | Helps you save for your first home or retirement |
| Innovative Finance ISA | Often involves peer-to-peer lending or other alternative assets |
| Junior ISA | For anyone under 18 who is a UK resident |
1. Cash ISA
A Cash ISA works like a regular savings account, but any interest you earn is completely tax-free. It is generally considered one of the lowest-risk ISA options, making it suitable for people who want to protect their savings while still earning interest. A Cash ISA is often best for short-term goals or for those who prefer certainty over investment risk.
2. Stocks and Shares ISA
A Stocks and Shares ISA allows you to invest in assets such as shares, funds, bonds and exchange-traded funds (ETFs). The value of your investments can rise or fall, meaning there is a higher level of risk. But it also offers the potential for greater long-term returns, making it a popular choice for people investing for future goals over several years.
3. Lifetime ISA
A Lifetime ISA (LISA) is designed to help people save money for their first home or for retirement. The government adds a 25% bonus to eligible contributions. Only people aged 18 or over but under 40 can open a Lifetime ISA. Once opened, you can continue contributing until age 50. Remember that the maximum that you can pay into this kind of ISA is £4,000 per year.
4. Innovative Finance ISA
An Innovative Finance ISA allows you to earn tax-free returns through alternative investments, such as peer-to-peer lending platforms and other forms of finance. These products can potentially offer higher returns than cash savings, but with some risks, including the possibility of losing your capital. They are generally more suitable for experienced investors who understand these risks.
5. Junior ISA (JISA)
There is also a Junior ISA for anyone under 18 who is a UK resident. A JISA has its own annual allowance of £9,000, which does not affect the £20,000 adult ISA limit. If you’re aged 16 or 17, you can still open a Junior ISA. Once you turn 18, it will automatically convert into an adult ISA.
Can I have ISAs with different providers?
In the 2026/27 tax year, you can have ISAs with different providers at the same time. For example, you could have a Cash ISA with one provider and a Stocks and Shares ISA with another. You can also transfer existing ISAs between providers if you find a better option.
Having ISAs with different providers can be useful if you want to access different products, interest rates or investment options. But keeping track of multiple accounts can become more complicated over time, especially if your savings and investments are spread across several platforms.
Transferring money from one ISA to another
If you have multiple ISAs from previous years—or you’d like to switch providers—you can now transfer them more flexibly
- Partial transfers are allowed, whether the contributions were made in the current tax year or in previous years.
- You can transfer any portion of your funds to another provider and still keep the original account open.
- Always use the official ISA transfer process offered by your new provider to maintain your tax-free status.
When it comes to Lifetime ISAs, keep in mind that transferring money out of a LISA to a different ISA type (or closing it) before you’re 60 and not buying a first home generally incurs a 25% government withdrawal charge. Also, if you withdraw ISA funds on your own and try to re-deposit them without using the official transfer process, you risk losing the tax protection on that amount if you’ve already reached your £20,000 contribution limit.
Transferring or consolidating your ISA with Moneyfarm
At Moneyfarm, we generally recommend consolidating your ISAs rather than spreading them across multiple providers. While it can be tempting to hedge your bets, if your current provider isn’t offering the performance or service you need, switching your entire ISA to Moneyfarm can be more efficient. However, you can also transfer part of your ISA, especially if it’s from a previous tax year.
Consolidating your ISAs can make it easier to keep track of your savings and investments. Instead of managing different accounts with multiple providers, you can have your ISA savings in one place. This can help simplify your finances and make it easier to monitor your progress towards your long-term goals.
Another benefit is avoiding the need to maintain multiple investment strategies across different providers. By bringing your ISAs together, you can ensure your portfolio is aligned with your risk profile, time horizon and financial objectives.
If you decide to transfer an ISA, it is important to use the official ISA transfer process rather than withdrawing the money yourself. Taking money out of an ISA and paying it into a new account could mean losing the tax-free status of those funds and may affect your annual ISA allowance. By using the transfer process, your money continues to benefit from its tax advantages. You can do this easily with Moneyfarm, we can help you to keep your savings and investments in one place.
Making the most of your ISA allowance
You can’t exceed £20,000 across all the ISAs you open or pay into during a single tax year (with £4,000 of that allowed for the LISA if you choose to fund one). With the ability to open multiple ISAs of the same type, consider these points
- Cash ISAs typically offer more stability but often have lower returns.
- Stocks and Shares ISAs can provide higher growth potential but carry more risk.
- Lifetime ISAs give you a 25% bonus toward retirement or a first home but have withdrawal restrictions.
- Innovative Finance ISAs can offer alternative investments but may be less liquid.
Be strategic about splitting your allowance to suit your goals—whether that’s maximising interest rates, investing for growth, or saving for a first home.
What happens if I exceed my ISA allowance?
If you accidentally pay more than your annual allowance, you should not try to fix the mistake by withdrawing the extra money yourself. Instead, your ISA provider will usually report the details to HM Revenue & Customs (HMRC), which will review the situation and decide how the excess contribution should be treated.
HMRC may contact you or your provider to correct the error. Depending on the circumstances, any excess amount may need to be removed from the ISA or the tax benefits on the excess contribution may be adjusted. The rules can vary depending on the type of ISA and the nature of the mistake.
To avoid exceeding your allowance, it is important to keep track of all ISA contributions you make across different providers during the same tax year. Remember that the £20,000 limit applies to your total contributions, not each individual ISA. For example, you can pay £10,000 into a Cash ISA and £10,000 into a Stocks and Shares ISA.
Seek professional advice
While the new flexibility allows you to open multiple ISAs in the same year, managing them effectively is key. If you’re unsure how to optimise your tax-free savings, it’s wise to seek guidance from a qualified financial adviser. Remember, investments can go down as well as up, and you should always choose products authorised and regulated by the Financial Conduct Authority (FCA).
A professional can assess your individual circumstances, including your objectives, investment horizon and attitude towards risk, and help you understand which options may be most suitable for you.
It is also important to remember that different types of ISAs come with different levels of risk. While Cash ISAs provide more certainty, investments held in a Stocks and Shares ISA can fall as well as rise, meaning you may get back less than you originally invested. The right choice will depend on your personal situation and how long you plan to keep your money invested.
Frequently asked questions
Who can open an ISA?
Any UK resident aged 18 or over can open an adult ISA, as can Crown employees working abroad (and their spouses or civil partners). If you’re under 18, you can open a Junior ISA.
Can you have more than one ISA of the same type in the same year?
Yes. From April 2024 onwards, you can open and pay into multiple ISAs of the same type in the same tax year, as long as your total contributions don’t exceed the annual allowance of £20,000.
How many ISAs can I open a year?
There’s now no limit to the number of ISAs you can open in one tax year. You could open several Cash ISAs, multiple Stocks and Shares ISAs, and so on—but remember, the maximum overall you can contribute is £20,000.
Can I pay into more than one Lifetime ISA?
You can open multiple LISAs over different years if you wish, but you can only fund one LISA in any single tax year, up to £4,000. This amount counts towards your overall £20,000 annual ISA allowance.
Can I have more than one Cash ISA?
Absolutely. You can now hold multiple Cash ISAs even within the same tax year, which can be helpful if you want to find the best interest rates or keep your cash spread across different providers.
What happens to ISAs from previous years?
They remain open unless you choose to close them or transfer the funds. You can also continue to contribute to old ISAs if it suits your strategy—just stay within the £20,000 yearly allowance.
Can I transfer money between ISAs?
Yes. Partial transfers are now permitted for current-year and previous-year contributions. That means you can transfer just a portion of your ISA balance, leaving the rest behind if you prefer. Always use your new provider’s official transfer process.
Can I withdraw money from an ISA?
Yes, you can usually withdraw money from an ISA, but the rules depend on the type of account and your provider. Cash ISAs generally offer easier access, while Stocks and Shares ISAs may require you to sell investments first. Remember that Lifetime ISAs have specific withdrawal rules and may include a government charge if you withdraw money for non-qualifying reasons.
Do ISA contributions reduce my tax bill?
No, unlike pensions, ISA contributions do not reduce your taxable income and do not provide tax relief. The main benefit of an ISA is that any interest, dividends or investment gains made within the account are protected from UK Income Tax and Capital Gains Tax.
What happens if I don’t use my ISA allowance?
Any unused ISA allowance cannot be carried forward to the next tax year. For 2026/27, you can contribute up to £20,000 across adult ISAs, but any unused portion will be lost when the tax year ends.
