A Nationwide Instant Access ISA works like a normal savings account, you can keep building up your balance each tax year saving up to your annual cash ISA allowance. The higher your balance the more interest you earn but unlike other savings accounts all the interest you earn is tax free so you get to keep it.
Cash ISAs are a flexible and tax-efficient way to save and everyone aged 16 or over can save up to £5,760 tax-free in a cash ISA with one provider, each tax year.
