Stocks and Shares ISA
What is a Stocks and Shares ISA?
A Stocks and Shares ISA is a special type of investment account you can use to grow your money, free from UK income and capital gains tax. Each year, you’re allowed to put in up to £20,000, and you can use that invest money into things like company shares or investment funds. If those investments make money, you get to keep it all—there’s no tax to pay on it. It’s an ideal way to boost your savings over the long term, as the government doesn’t take a cut of your returns.

How does a Stocks and Shares ISA work?
Think of a Stocks and Shares ISA like a box that holds your investments. You open the Stocks and Shares ISA account, add your money, and then choose what to invest in—this could be shares in companies, ready-made investment funds, or even government and corporate bonds. You don’t need to be an expert; many ISA providers offer easy ways to pick investments or even manage them for you.
Once your money is invested, it can grow over time depending on how the investments perform. Some might pay you income (called dividends or interest), and some might go up in value. The best part? Everything you earn inside the ISA stays yours—you won’t pay tax on any of it.
You can take your money out whenever you want, although it’s usually best to leave it invested for a few years to ride out the ups and downs of the market.
Benefits of a Stocks and Shares ISA
A Stocks and Shares ISA offers several advantages: you can access your money whenever you need it, start investing with as little as £1 a month with some brokers, and have the freedom to choose your own investments, all while enjoying tax-free growth—there’s no capital gains tax on any profits, no tax on dividends, and no tax on interest earned, making it a flexible and tax-efficient way to grow your money.
It’s a perfect choice if you have goals that are at least 5 yearsa way, like saving for retirement, buying a house, or putting money aside for your children’s’ future. The longer you leave your money to grow, the more it can increase in value through the power of compounding. So, if you’re looking to save for something important or just want to build up your wealth over time, a Stocks and Shares ISA is a smart way to do it.

How does the ISA allowance work?
Every tax year, the UK government gives you a set amount of money you can put into ISAs—this is called your ISA allowance. For the 2025/26 tax year, that allowance is £20,000.
You can split this allowance across different types of ISAs—like a Cash ISA, Stocks and Shares ISA, or Lifetime ISA—but you can’t go over the £20,000 total.
You can only pay into one of each type of ISA per tax year. So you can’t open two Stocks and Shares ISAs in the same year, but you can have one Cash ISA and one Stocks and Shares ISA, for example.
Also, your allowance resets every year on April 6th, so if you don’t use it, you lose it.
