What is an ISA?

An ISA is a ‘tax-efficient wrapper’ designed to go around an investment. Types of ISA include a Cash ISA and Stocks & Shares ISA. A Cash ISA is like a normal deposit account, except that you pay no tax on the interest you earn. Stock & Shares ISAs allow you to invest in equities, bonds or commercial property without paying personal tax on your proceeds.

Some ISAs do tie your money up for a significant period of time. However, others are pretty flexible. If you’re after flexibility, variable rate Cash ISAs don’t tend to have a minimum commitment. This means you can keep your money in one of these ISAs for as long – or as short – a time as you like. This type of ISA also allows you to take some of the money out of the ISA and put it back in without affecting its tax-efficient status.
