ISA or Savings Account: Which Is Best For Me?

Whether you should open an ISA or a traditional saver mostly depends on how much you want to save and for how long. We explain the differences between them.

ISAs have been protecting our money from tax for more than 20 years now. But with interest rates having climbed to decade highs, traditional savings accounts can still look attractive. Here we explain the differences between the two.

What is an ISA?

Individual savings accounts (ISAs) allow you to save a set amount each year to grow tax-free for as long as it remains in the account. The amount you can save in an ISA is called your ISA allowance, and it currently stands at £20,000 a year for 2024/25.

There is a whole range of ISA types, including cash ISAs, stocks and shares ISAs, lifetime ISAs, innovative finance ISAs and junior ISAs.

Cash ISAs are very similar to traditional savings accounts. You get a variety of cash ISAs in the same way you get lots of different savings accounts. Types of cash ISAs include:

The easiest way to think of a cash ISA is to imagine it as a wrapper around a savings account protecting it from tax.

What’s the difference between ISAs and savings accounts?

There are a number of differences between ISAs and ordinary savings accounts.

1. Tax

The key difference between an ISA and a savings account is the tax you pay on your returns. When you earn interest on your savings it is liable for income tax. Basic-rate taxpayers can earn up to £1,000 interest a year before income tax is due, and higher-rate taxpayers can earn up to £500. This is known as the personal savings allowance. If you earn more interest than that, it will be taxed. Additional-rate taxpayers have no personal savings allowance and must pay tax on all interest earned.

In contrast, ISAs are completely tax-free regardless of how much interest you earn.

2. Deposit limits

You can put as much money as you like into a savings account, unless there is a limit imposed by the bank or building society.

In contrast, you have an ISA allowance that limits how much you can pay into ISAs each tax year. It is currently £20,000.

3. Account limits

You can only pay into or open one cash ISA each tax year, but you can open as many savings accounts as you like.

Should I open an ISA or an ordinary savings account?

The answer to this really comes down to how much money you want to save and how long you plan to save it.

If you are saving small amounts for a short-term goal, then a savings account will likely be the better option as it’s unlikely that you will exceed the personal savings allowance.

Anyone who is looking for a home for a large amount of money, though, should consider an ISA. With an ISA you never have to worry about your interest exceeding the personal savings allowance. It will always be tax-free.

Similarly, if you are saving for a long-term goal, then putting your money into an ISA means it remains sheltered from tax as it grows.
