As autumn approaches, you might be reviewing how your money has performed this year and what to do next. If you’ve already made full use of your ISA allowance, that doesn’t necessarily mean you need to stop investing. You can still put spare money to work, although the tax rules can, and often do, change.
Understanding ISA allowance limits
An ISA allows you to save or invest money without paying UK Income Tax or Capital Gains Tax on account returns. That said, the government limits how much you can contribute during each tax year.
For the 2026/27 tax year, the overall ISA allowance is £20,000. Once you have contributed that amount, you can’t add more until the next tax year begins. Withdrawals generally don’t restore your allowance unless you use a flexible ISA and meet the relevant rules.
If you still have money available for longer-term goals, you might therefore consider investing outside an ISA rather than leaving it uninvested simply because you have reached the limit.
Investing beyond tax-wrapped accounts
You can hold investments outside tax-efficient wrappers. This gives you scope to keep building your portfolio without waiting for a new ISA allowance.
For example, suppose you have contributed £20,000 to ISAs and later receive a £5,000 work bonus. If you have an emergency fund and don’t need that money soon, you could invest some or all of it elsewhere. Unlike an ISA, however, your returns may create a tax liability.
Considering additional investment options
One common option is a general investment account. It can usually hold investments such as funds, shares and bonds, and it doesn’t have the same annual contribution ceiling as an ISA.
This flexibility can help if you regularly invest larger amounts or receive a lump sum. You can also sell holdings and withdraw your money when you choose, subject to the terms of your investments. Before contributing, check that your chosen assets suit how long you expect to invest.
Tax and investment considerations
Tax becomes more important outside an ISA. Depending on your circumstances, dividends and interest may attract tax, while profits when you sell investments can count towards Capital Gains Tax.
Your investments can also fall in value, regardless of which account you use. Consider both potential tax costs and investment risk rather than choosing an account solely because it accepts further contributions.
Keeping records of purchases, sales and income can make it easier to work out whether you need to report or pay tax.
Finding the right fit for your circumstances
Start with what you want your money to achieve and when you expect to need it. Money for a house deposit in two years, for example, may call for a different approach from money you are investing for retirement in 20 years.
Your tax position, existing portfolio and tolerance for market falls also matter. Personalised financial advice can help you weigh these factors and choose an approach that fits your wider financial plans.
