What is an Individual Savings Account (ISA)?
An Individual Savings Account (ISA) is a tax-free savings and investment product approved by the UK Government. It allows you to save or invest money without paying tax on the interest, dividends, or capital gains earned within the account.
ISAs are a simple means of building tax-free savings—perfect for long-term planning, putting down a deposit on a property, or growing an investment portfolio.
Important ISA Features
- Tax-free income: No capital gains tax or income tax on funds earned within the ISA.
- Annual limit: In the 2024/25 tax year, you can save up to £20,000 across all your ISAs.
- Flexible choices: You can choose between cash savings, investments, or a combination of both.
- One of each form, each year: You may contribute to only one of each type of ISA per tax year (e.g., one Cash ISA, one Stocks and Shares ISA, etc.).
