What is a stocks and shares ISA?
A stocks and shares ISA allows UK residents to invest up to £20,000 per tax year in shares, funds, and bonds without paying tax on the gains or income, making it a popular choice for long-term wealth building. This tax wrapper helps protect your investments from capital gains tax and dividend tax, potentially boosting returns over time. For 2025/26, the ISA allowance remains £20,000 across all ISA types, as confirmed by HM Revenue & Customs (HMRC guidance, accessed 2025).
Benefits and tax advantages
The main benefit is tax-free growth; for example, if your investments yield 7.2% annual returns as averaged over the past five years ending 2025, you keep every penny of profit. Unlike taxable accounts, there’s no 20% basic rate tax on dividends or 10-20% on gains, which can save thousands for moderate investors. This makes stocks and shares ISAs ideal for those eyeing retirement or major goals, with historical data from MoneySavingExpert showing strong performance against inflation.
How it differs from cash ISAs
While cash ISAs offer secure, interest-bearing savings similar to a bank account, stocks and shares ISAs involve market investments with potential for higher returns but also volatility. Cash ISAs suit short-term savers, yielding around 4-5% in 2025, whereas stocks and shares can deliver more over time, though with risk of loss. If you’re new to investing, start small in a stocks and shares ISA to balance growth and safety.
Eligibility and allowance
You must be 18 or over and a UK resident to open one, with the £20,000 allowance resetting each tax year from 6 April to 5 April. You can split the allowance across ISAs, but total contributions can’t exceed it. For families, consider junior versions for children under 18, though this article focuses on adult options.
