Choose an ISA that works best for you
Cash ISAs are a simple, tax-free way to save. They could make your money work harder than a traditional savings account.
What is a cash ISA?
- An ISA (Individual Savings Account) is sometimes known as a 'tax wrapper' as you won't have to pay income tax on the interest you earn.
- You can pay in up to £20,000 in this tax year across all ISA accounts you hold as part of your annual ISA allowance.
- Royal Bank offers two types of cash ISA for over 18s; an Instant Access cash ISA and a Fixed Rate cash ISA.
Is a Fixed Rate ISA best for you?
- Fixed interest for long term savings with tax-free benefits.
- Choose a term and open your account with £1,000.
- Fix your saving interest rate, so you know exactly what your pot will earn.
