ISAs – bigger and better than ever

One of the highlights of the 2017/18 tax year was the increase to the annual ISA limit. While pension allowances have continued to shrink in the last few years, the annual ISA allowance has gradually leapt from £7,000 in 1999 to a whopping £20,000 – that’s £40,000 per couple. Unlike pensions, there is no limit to how much money you can hold in an ISA either. ISAs have many other benefits that make them a really useful and important investment account for people of all ages. Read on to find out more.

The advantages of ISAs

  • ISAs have great tax benefits. The interest you make on cash savings or the gains from investments within an ISA are free from Income Tax and Capital Gains Tax
  • You have easy and immediate access to your money. This is particularly useful if you are under the age of 55 and cannot access your pension
  • Unlike a pension, there is no limit to how much you can hold within an ISA

ISA growth in action

The best way to see the benefit of ISAs is to look at how much money you could have made if you’d invested the full allowance every year since ISAs were first made available in April 1999. Over 18 years you would have invested a total of £186,560 tax-free, and this would have grown by £191,954.54 to give you a total of £288,505.54 (assuming 5% annual growth)*.

You could have £288,000 if you’d invested the full ISA allowance each year and achieved 5% annual growth.
