An Individual Savings Account (ISA) is a tax-efficient investment account available to residents of the United Kingdom. It allows individuals to save or invest money without paying tax on any interest, dividends, or capital gains earned within the account. ISAs offer a wide range of investment options, including cash, stocks and shares, and innovative finance products, making it a flexible and accessible way to grow one’s savings. The annual allowance for ISAs is set by the government and any contributions made within this limit are not subject to income tax or capital gains tax. ISAs are a popular choice for long-term savings and can help individuals achieve their financial goals while minimizing their tax liability.
