What is an ISA platform?

An ISA platform is typically a type of Stocks and Shares ISA account in which you choose your own investments.

An ISA account is a tax-free savings account, and a Stocks and Shares ISA allows you to invest your ISA funds into the stock market via a range of investment vehicles.

What are the tax benefits of an ISA?

ISA savings are completely free from the following taxes that are usually paid on investments you’d hold outside of a tax-free account:

  1. Income tax on dividends
  2. Income tax on interest
  3. Capital Gains Tax (CGT) in investment growth

You can invest up to £20,000 in an ISA each tax year – this is your annual ISA allowance.

What does a Stocks and Shares ISA platform invest in?

You’ll usually be required to choose your investments yourself in an ISA platform, although some providers do offer ready-made portfolios that are built for you and then managed by professionals.

Here are some of the most popular types of ISA platform investments:

  1. Shares

Individual shares of companies that are traded on a live stock market such as the London Stock Exchange.

  1. Managed Funds

Including investment trusts, OEICs and unit trusts, these are investment funds that operate in a specific sector managed by investment professionals.

  1. Tracker Funds

Including index funds and ETFs (Exchange Traded Funds), these track a specific index or sector by investing proportionately in the companies within them. They are not actively managed by a fund manager so typically have lower charges than managed funds.

  1. Bonds

Bonds are forms of corporate or government lending that you can invest in to receive an annual target interest rate. They are classed as low risk compared to other stock investments, but they can still depreciate in value.

How to Compare ISA Platforms

Here are some of the most important factors to consider in an ISA platform comparison:

  1. Can they hold all the assets in your portfolio?

If you know what shares and funds you’ll be holding in your account, check that your new ISA platform can support the investments. Particularly if they are overseas stocks or if they are listed on a smaller stock exchange.

  1. What are the annual platform charges?

Some platforms charge more for holding shares compared to funds, or vice versa, so make sure you compare the platform charges to your own portfolio to see how much you’ll be paying.

Some providers also charge a percentage of your portfolio as opposed to a flat fee – this may be cheaper for you if you have a smaller account.

  1. Are there any ad hoc platform charges to consider?

Dealing fees can be expensive through some ISA platforms, so if you’re a frequent trader you’ll want to compare the charges in comparison to the ongoing fees.

You should also look out for other admin fees such as account closure fees and transfer out fees.

  1. What platform features are available?

Certain trading features are invaluable to ISA investors that buy and sell shares frequently. The most important ones include price notifications, limit orders and stop losses.

The online ISA platform itself also needs to be reliable, functional and easy to use. Some providers allow you to open a fake, free ISA account to test out the platform with.

  1. What about customer service ratings?

Remember, a more expensive ISA platform may be reinvesting your charges into their customer service teams. If you’re new to DIY investing, this could be the best online ISA platform for you, as you’ll likely have questions that need answering.
