Why choose an ISA?

An ISA is a simple, tax-free way to save. That means that you won't pay tax on any interest that you earn, so it could make your money work harder than a traditional savings account.

Thinking of saving for something special or looking to build a rainy day fund? Using this year's tax-free ISA allowance could help you reach your goals faster and stop you missing out on valuable tax benefits.

For Fixed Rate ISA no withdrawals or deposits during the term. Available to new customers until 12 March 2025. Available to existing customers until 17 March 2025. Please note that these issues may be withdrawn early due to limited availability. Interest is calculated daily and paid annually to your ISA on the first business day in April and on the Maturity Payment Date. Early closure fees may apply.

Transferring from an existing ISA

An ISA transfer is when you switch your ISA savings from one provider to another. You might do this to get a better interest rate, or to take advantage of a different type of ISA altogether. You can transfer an existing ISA elsewhere into your NatWest Cash ISA at any time, bringing all your ISAs together in one place.

Definitions

Annual Equivalent Rate (AER) shows the interest rate if interest is paid and compounded once each year. AER helps you to compare the rates of interest on different accounts.

Compound interest is interest that is earned on interest that’s already been paid.

Gross means the interest rate you are paid on your savings with no compounding.

p.a. per annum (per year).

Tax-free.  We pay all savings interest without the deduction of tax.  You do not pay any UK tax on interest earned in ISAs. You may have to pay tax on interest earned in non-ISA accounts depending on your Personal Savings Allowance. The tax treatment may be subject to change in the future.
