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, bonds and other assets without paying tax on any capital gains, dividends or interest earned. This tax wrapper makes it a popular choice for long-term savings, especially with the annual ISA allowance remaining at £20,000 for the 2025/26 tax year as implied by HMRC guidelines. Unlike cash ISAs, which offer predictable interest but lower returns, stocks and shares ISAs can grow faster through market investments, though they come with higher risk.
Eligibility is straightforward: you must be 18 or over and a UK resident, with one ISA subscription per tax year across all types. For more on the basics, see our guide on what is a stocks and shares isa. Around 15 million adult ISA accounts were subscribed to in 2023-2024, showing a surge in popularity driven by tax benefits, according to GOV.UK’s annual savings statistics from September 2025 (GOV.UK annual savings statistics).
Key benefits include tax-free growth, which can significantly boost returns over time. However, investments can fall as well as rise, so it’s suited for those comfortable with volatility. To compare with safer options, check our article on stocks and shares isa vs cash isa.
