Yes. Since April 2024, you can open and contribute to multiple Stocks and Shares ISAs in the same tax year. You can also hold multiple Cash ISAs and split your 20,000 pound annual allowance across as many ISAs as you like, with any providers you choose. The only restrictions are: you can only have one Lifetime ISA, and Junior ISAs are limited to one Cash JISA and one Stocks and Shares JISA per child.
What Are the Multiple ISA Rules for 2025/26?
Before April 2024, you could only contribute to one Stocks and Shares ISA per tax year. If you opened a Stocks and Shares ISA with Trading 212, you could not also contribute to one with Vanguard in the same year.
This rule was scrapped. You can now open and contribute to as many ISAs of the same type as you want, provided your total contributions across all ISAs do not exceed 20,000 pounds per tax year.

| ISA Type | How Many Can You Have? | Rules |
| Stocks and Shares ISA | Unlimited | Total contributions across all must not exceed 20,000 pounds |
| Cash ISA | Unlimited | Total across all must not exceed 20,000 pounds |
| Lifetime ISA | One only | Maximum 4,000 pounds/year (counts towards 20,000 pound total) |
| Innovative Finance ISA | Unlimited | Total across all must not exceed 20,000 pounds |
| Junior Stocks and Shares ISA | One per child | 9,000 pounds/year (separate from adult allowance) |
| Junior Cash ISA | One per child | Share of 9,000 pounds with Junior S&S ISA |
Why Would You Want More Than One Stocks and Shares ISA?
Access different investments: Different platforms offer different products. You might use Vanguard for their LifeStrategy funds and Trading 212 for individual shares and wider ETF range.
Compare platform features: Try a new platform with a small amount before committing your full portfolio.
Separate investment strategies: Keep your long-term index fund portfolio separate from a more active stock-picking account.
Spread FSCS protection: FSCS covers 85,000 pounds per provider. If your ISA portfolio exceeds this, spreading across providers increases your protection.

Take advantage of best rates: For Cash ISAs, different providers offer different rates. You can now use the best rate at each provider.
How Does the 20,000 Pound ISA Limit Work Across Multiple ISAs?
The 20,000 pound ISA allowance is your total across all ISA types and providers. Here are some examples of how you could split it:
| Example | ISA 1 | ISA 2 | ISA 3 | Total |
| All in one | 20,000 pounds S&S ISA (Trading 212) | - | - | 20,000 pounds |
| Split by platform | 10,000 pounds S&S ISA (Vanguard) | 10,000 pounds S&S ISA (Trading 212) | - | 20,000 pounds |
| Mix ISA types | 12,000 pounds S&S ISA | 4,000 pounds LISA | 4,000 pounds Cash ISA | 20,000 pounds |
| Three S&S ISAs | 8,000 pounds (InvestEngine) | 7,000 pounds (Trading 212) | 5,000 pounds (AJ Bell) | 20,000 pounds |
It is your responsibility to ensure you do not exceed 20,000 pounds in total. HMRC does not monitor this in real-time, but if you exceed the limit, you will need to contact HMRC to remove the excess, which will lose its tax-free status.
Do Old ISAs From Previous Years Count Towards Your Allowance?
ISAs from previous tax years do not count towards your current allowance. You could have 200,000 pounds across multiple old ISAs and still contribute 20,000 pounds in the current year. You can leave old ISAs with their existing providers, transfer them to a new provider, or consolidate them into one account. Transferring does not use your allowance.
Can You Transfer Part of Your ISA to Another Provider?
From the 2025/26 tax year, you can make partial transfers between ISA providers. This means you can move some of your ISA to a new provider while keeping the rest where it is. Previously, current-year contributions had to be transferred in full or not at all.
Frequently Asked Questions
Can I put 20,000 pounds into each ISA?
No. The 20,000 pound limit is your total across all ISAs combined. Putting 20,000 pounds into two ISAs would mean you have contributed 40,000 pounds, which exceeds the allowance.
What happens if I exceed my ISA allowance?
Contact HMRC on 0300 200 3300. They will instruct you to withdraw the excess amount, which will lose its tax-free status.
Can I have an ISA with the same provider twice?
Generally no. Most providers only allow one Stocks and Shares ISA per customer. The multiple ISA rule applies to having ISAs with different providers.
Do transfers count towards my allowance?
No. ISA transfers between providers do not use any of your annual allowance.
Can my spouse and I share an ISA allowance?
No. Each person has their own individual 20,000 pound ISA allowance. However, you can each open ISAs to effectively shelter 40,000 pounds per year as a couple.
