Can I Have More Than One Stocks and Shares ISA?

For years the rule was simple but restrictive: you could pay new money into only one stocks and shares ISA per tax year. That changed on 6 April 2024, when the Government relaxed the ISA rules. You can now open and contribute to as many stocks and shares ISAs as you like within a single tax year, with different providers if you wish, provided your combined contributions never exceed the £20,000 overall allowance.

This is a genuine liberalisation. Previously, if you wanted to try a new platform mid-year you had to either transfer your whole ISA across or wait until the next 6 April. Now you can, for example, run a low-cost index portfolio with one provider and open a second stocks and shares ISA elsewhere to hold a different strategy, all in the same year, all tax-free.

Holding ISAs from previous years

Even before the 2024 change, there was never any limit on how many ISAs you could hold in total. Every tax year you could fund a new one, so many long-term savers have accumulated a dozen or more ISAs across different providers over their investing lives. All of them keep their tax-free status indefinitely; the annual rule only ever governed where new money could go.

The one rule that still bites: the £20,000 limit

The freedom to open several ISAs does not increase how much you can shelter. Your total new contributions across every ISA, cash, stocks and shares, innovative finance and lifetime, must still fit inside £20,000 for the year. Split £10,000 into one stocks and shares ISA and £10,000 into another and you have used your whole allowance. Our answer on how much you can put in a stocks and shares ISA sets out the sub-limits in detail.

Should you actually have more than one?

You can, but that does not always mean you should. For most people, a single well-diversified stocks and shares ISA is cheaper and far easier to manage than several scattered accounts. Multiple ISAs make most sense when a second platform genuinely offers something the first cannot, or when you want to separate distinct goals.

Transfers versus new subscriptions

It is worth being clear on the difference between paying new money into several ISAs and transferring existing ISAs between providers, because people often confuse the two. New contributions count towards your £20,000 allowance; transfers do not. So you can move an old ISA worth £50,000 to a better-value platform and still pay a fresh £20,000 into an ISA in the same year: the transfer sits entirely outside the annual limit.

The golden rule with transfers is never to simply withdraw the cash and re-pay it, as that would strip the money of its tax-free wrapper and use up your allowance. Instead, ask the receiving provider to arrange an ISA transfer directly. You can transfer current-year subscriptions too, but if you do, you must move the whole of that year’s money, not just part of it. Most transfers of investments held as funds can be done “in specie”, meaning your holdings move across without being sold, so you stay invested throughout and avoid being out of the market while the transfer completes.

Consolidating scattered ISAs onto a single platform is one of the most common reasons people move money, it cuts paperwork, can lower fees and makes it far easier to see your true asset allocation. Because platform fees, fund charges and dealing costs vary widely, spreading small amounts across several providers can quietly erode returns. A regulated adviser can help you decide whether consolidation or separation serves you better, Vetted Wealth matches you free with an independently vetted, FCA-regulated adviser via the investment management service. As ever, investments can fall as well as rise, and this is information rather than personal advice.
