Make the most of your ISA allowance

An ISA is a tax-efficient way to save or invest. The annual ISA limit for the 2017/2018 tax year is £20,000. This amount can be paid into any combination of permitted ISAs in the same tax year, you can only pay into one of each type of ISA in any one tax year. See our Guide to ISAs page for more information.

The favourable tax treatment of ISAs may change in the future.

Stocks and Shares ISAs

Depending on your financial goals and plans for the future, if you can afford to put your money away for the medium to long term (usually for five years or more), then you might be interested in investments. They give you the potential to make higher returns over the longer term than saving.

Stocks and Shares ISAs are a tax efficient way to invest giving you the potential for higher returns than savings accounts over the longer term, typically for at least 5 years or more. All investments carry varying degrees of risk to your money. 

The value of investments and any income from them can go down as well as up and you may get back less than the full amount you invest.

  • All our ISAs allow access to your money but there may be restrictions or charges that vary depending on which ISA it is that you hold.
    Be aware that if you take money out, and you wish to put it back later, this will count against your annual ISA allowance for that tax year. This means that if you have already used up your annual ISA allowance, any money you take out cannot then be put back in during the same tax year.


    Santander ISAs don’t offer additional flexibility. Take a look at our information pages to learn more.

AER explained
AER stands for Annual Equivalent Rate and shows what the interest rate would be if we paid interest and added it to your account each year.

Tax-Free explained
The tax-free rate is the rate of interest payable where interest is exempt from income tax. The favourable tax treatment of ISAs may change in the future.

Interest is calculated daily and paid annually.
