ISAs
We have two kinds of cash ISA. Fixed Rate Cash ISAs give you a fixed interest rate for a set time, but you have restricted access to them. Cash ISAs have a variable rate of interest, but are instant access (and stay open for as long as you like).
- You can earn tax-free interest on this savings account.

Take advantage of your ISA allowance.

This is the maximum you can pay into an ISA in any tax year. HM Revenue & Customs (HMRC) sets the annual ISA allowance. To find out what it is, check either our website Fixed Rate Cash ISAS or HM Revenue & Customs on https://www.gov.uk/indivdual-savings-accounts
This stands for Annual Equivalent Rate. It shows you what the interest rate would be like if your interest was paid and compounded once a year.
Tax-free is the contractual rate of interest payable where interest is exempt from income tax.
