An ISA is generally better for higher earners or those with significant savings because interest is tax-free, protecting it from the Personal Savings Allowance (PSA) limit. However, a standard savings account often offers higher interest rates and more flexibility, making it better for smaller amounts or short-term needs, provided interest stays within your tax-free allowance (£1,000 for basic rate, £500 for higher rate).

Is it better to put money in an ISA or savings account?

Cash ISAs are tax-free. You won't pay tax on any interest you earn. At NatWest, we offer an instant access Cash ISA, and a Fixed Rate ISA with a set term. On the other hand, the interest you make on normal savings accounts may be taxed, if it's more than your Personal Savings Allowance.

Should I move my ISA to my savings account?

There are two reasons to open a savings account over a Cash ISA. The interest rate is better than the ISA AND the interest earned is below your personal savings allowance so you don't pay any tax on it. This is pretty rare in the current market but wasn't the case a few years back.

What are the disadvantages of an ISA account?

Because of the way in which interest rates can fall, as well as rise, there is a risk that savings held in a cash ISA may struggle to keep pace with inflation. In other words, even though your cash balance is steadily increasing, your money may be worth less in real terms as things become more expensive to buy.
