13 ISA investing myths dispelled

13 ISA investing mythsAs well as getting asked lots of questions about ISAs, we find that when we speak to clients, they have many false assumptions about what you can and can’t do with ISAs. We call these ‘ISA myths'.

To help, we've put together a list of the 13 most common ones.

13 ISA myths that are false

1. ISAs are risky – FALSE

Did you know that an ISA isn’t an investment? True, an ISA is a wrapper that money is kept in to protect it from the taxman. Think of an ISA as a shield that prevents the taxman from being able to touch your investment returns. Any risk comes from the investments that you have chosen to hold within the ISA, not from the ISA itself.

2. With a stocks and shares ISA, you are not able to park in cash – FALSE

If you believe a bear market (major downtrend) has been triggered, you can move out of your fund and into the safety of cash via an ISA Cash Park. If you are ever unsure of where to invest your ISA money, you can also use an ISA Cash Park.

3. You can only open one ISA – FALSE

Some people mistakenly think that you can only open one ISA in your lifetime. The rules allow all adults to open up a new ISA each and every year. Remember that if you have a partner, they can also open one ISA per year.

4. It’s impossible to make a million with ISAs – FALSE

As reported by FT.com on October 8th 2010, scores of people are now ISA millionaires, with £1 million-plus in tax sheltered holdings – including some with portfolios worth £12 million.

5. Investing in ISAs means my money is locked up – FALSE

There is no minimum term for which the investment must be made and the tax advantages start on day one when investing in an ISA. It is always possible to gain easy access to all or part of your savings, subject to any restrictions that may be included on a particular ISA product.

6. It is best to invest in an ISA at the end of the tax year – FALSE

The tax advantages of an ISA start the day that the money is invested so, by investing earlier in the tax year, you gain more potential advantage. Since investing in ISAs back in 1997, in 95% of cases, we’ve added at the beginning of the year rather than the end. Remember that as soon as the year’s allowance is invested, it will start to receive its tax-boost, and the longer you delay investing throughout the tax year, the smaller the boost it will get in that year. 

7. If you invest in ISAs, you have to fill out a tax return – FALSE

Tax savings occur automatically within the ISA and ISAs do not have to be recorded on your tax return. You also do not need to inform HMRC (the taxman) that you have an ISA.

8. Opening an ISA is complicated – FALSE

It takes us literally minutes each year to take out a new ISA. It is a common mistake to think that opening an ISA is complicated. We can assure you that it's really easy.

9. Transferring an ISA to another manager is complicated – FALSE

ISAs can be transferred at any point to a new location such as moving from one fund supermarket to another. Your existing platform cannot stop you from moving, but they may make a charge or force you to sell any assets to be transferred as cash. Any charges that apply will be in the terms and conditions and should be considered when shopping for an ISA.

It may also take a few weeks to complete the transfer. If you believe the delay has been unreasonable, you should contact both providers and, if you are still unhappy, complain to the Financial Ombudsman.

10. Teenagers are not allowed to own an ISA – FALSE

If you have a son or daughter who is either 16 or 17 and a UK resident they are allowed to open a cash ISA, but to open a stocks and shares ISA they would need to wait until they were at least 18.

11. If I move abroad I’ll lose my ISAs – FALSE

It's true that you can only open an ISA if you are resident in the UK for tax purposes. If you move abroad you won't be able to open a new one or fund an existing one. You will, however, be able to keep your ISA and still get tax relief on investments held within it. Government employees, such as diplomats, are exempt from this. If you work overseas and are paid by the Government, you may open and fund an ISA.

12. I have to invest my ISA money all in one place – FALSE

If you choose a stocks and shares ISA you can mix up the way your money is invested by choosing a range of funds which provide exposure to different countries, sectors and markets around the world.

13. You are not allowed to transfer cash ISAs into stocks and shares ISAs – FALSE

Many of our clients have moved money from a cash ISA into a stocks and shares ISA. If the cash ISA is from a previous tax year, you can move as much or a little as you like. If the cash ISA is from the current tax year, you must move all of it. You will however, be free to invest in another cash ISA, subject to the overall investment limit.
