AER explained

AER stands for Annual Equivalent Rate and shows what the interest rate would be if interest was paid and each year. All ISA interest is paid tax-free, which means it's exempt from income tax. We pay all non-ISA savings interest gross, which means no tax is deducted. It's your responsibility to pay any tax due, based on your individual circumstances. Tax rules may change in the future.
