Saving and Investing
Make each day count. Explore our tax-efficient ISAs
You must be a UK resident aged 18+. You can only subscribe to one cash ISA with NatWest in current tax year (2025/26) up to £20,000. Tax free interest means interest payable is exempt from UK income tax and Capital Gains Tax. Tax reliefs referred to are those applied under current UK legislation, which may change.
Investing puts your capital at risk. The value of investments can fall as well as rise, and you may not get back the full amount you invest. Eligibility criteria and fees apply.
Why choose an ISA?
ISAs offer tax-efficient ways to save your money without paying UK Income Tax or Capital Gains Tax on your interest or returns.
Take advantage of your £20,000 ISA allowance for this tax year (2025/26).

Saving with a cash ISA and investing with Stocks and Shares and Junior ISAs
Cash ISAs are similar to a regular savings account. The difference is that the interest you earn is tax-free.
Stocks and Shares and Junior ISAs are investment products and so the value of your investments could go up and down depending on market changes.
Each tax year you can contribute up to a total of £20,000 across both a cash ISA and a Stocks and Shares ISA. The annual tax year allowance for a Junior ISA is £9,000 per child.
