Want to Save Smarter? Learn Exactly How Many ISAs You Can Have and Make the Most of Them
When saving money in the UK, ISAs are a big deal. But one question keeps popping up: how many ISAs can you have? The rules feel like a puzzle. You might hear one thing from your bank and another from your neighbor. I’m here to break it down in plain English—no jargon, no confusion.
Let’s walk through how ISAs work, how many you can open, and how to use them to grow your money faster.
What Is an ISA?
ISA stands for Individual Savings Account. It’s a special kind of savings or investment account that lets you earn interest or returns without paying tax on it. That’s the magic.
There are a few main types of ISAs:
- Cash ISA – A simple savings account with tax-free interest.
- Stocks and Shares ISA – For investing in the market, also tax-free.
- Lifetime ISA (LISA) – For first-time homebuyers or retirement savings.
- Innovative Finance ISA – For peer-to-peer lending investments.
- Junior ISA – This is for saving on behalf of your child.
Now, let’s get to the real question.
How Many ISAs Can I Have?
Here’s the deal: You can have multiple ISAs, but you can only open and pay into one of each type per tax year.
So, yes, you can hold several ISAs from previous years. But within a single tax year, you’re only allowed to:
- Pay into one Cash ISA
- Pay into one Stocks and Shares ISA
- Pay into one Lifetime ISA
- Pay into one Innovative Finance ISA
That means you can put money into four different ISAs in one tax year, as long as each is a different type.
Let’s say you’ve got an old Cash ISA from a few years ago. You can keep it and even open a new one this year—just don’t put money into both in the same year. Make sense?
Real-Life Example
Imagine Lucy, a 28-year-old teacher. She has:
- A Cash ISA from 2020
- A Stocks and Shares ISA from 2022
- A new LISA for her first home
In the 2024/25 tax year, she opens a new Cash ISA and contributes only to that one. She leaves the old one alone. That’s fine. She’s following the rules and building her savings smartly.
Why This Matters
You want to make the most of your ISA allowance, which is currently £20,000 per tax year. Using a mix of ISA types can help you reach different goals—like buying a house, saving for retirement, or investing long-term—all while keeping your returns tax-free.
Tips for Managing Multiple ISAs
- Keep track of which ISA you paid into each year.
- Don’t go over your total £20,000 limit across all ISAs.
- Review rates regularly—switch if your current ISA is underperforming.
- Use your allowance before the tax year ends, or you lose it.
Final Thoughts and Next Steps
Understanding how many ISAs you can have helps you save, plan smarter, and grow your money without the tax bite. The key is using your ISA types wisely and keeping your strategy simple.
