What is a stocks and shares ISA?
A stocks and shares ISA offers a tax-efficient way to invest in the stock market, allowing your money to grow without paying income tax or capital gains tax (CGT) on profits. Unlike a cash ISA, which provides steady but low interest, this type lets you buy shares, funds, bonds, and exchange-traded funds (ETFs), potentially delivering higher returns over the long term though with greater risk. For 2025, the annual ISA allowance stands at £20,000, meaning UK residents aged 18 or over can invest this amount tax-free each tax year, as confirmed by HM Revenue & Customs (HMRC) at https://www.gov.uk/individual-savings-accounts.
Eligibility requires a UK address and National Insurance number, and you can split the allowance across different ISA types. This makes it ideal for building wealth for retirement or major goals. However, remember that investments can fall as well as rise, so capital is at risk.
