Fixed Rate ISA Savings Account

If you want to invest a lump sum then a Fixed Rate ISA offers a tax-free interest rate that won't change during your chosen term.

Cash ISAs are a flexible and tax-efficient way to save and everyone aged 16 or over can save up to £5,640 tax-free in a cash ISA with one provider, each tax year. With most savings accounts, the tax man gets a cut from the interest you earn. That's why it's reassuring to know that with a cash ISA all the interest you earn, you keep.

Key features

  • Enjoy a fixed tax-free rate of interest during the term of your cash ISA account
  • Open your fixed rate cash ISA account with as little as £1 in any Nationwide branch
  • Open more than one Fixed Rate ISA - subject to your annual cash ISA limit
  • Choose to have your interest paid monthly or annually
  • Part of our Cash ISA range - tax-free interest products offering a range of access options to suit your needs.

AER stands for Annual Equivalent Rate and illustrates what the interest rate would be if interest was paid and compounded once each year.

The gross rate of interest is the interest rate payable before any income tax is deducted (if you do pay tax).

Tax-free is the contractual rate of interest payable where interest is exempt from income tax.

The tax information provided is based on our current understanding of current law and HM Revenue & Customs practice which can change.
