Investment Dealing Account

Investing on your terms

A flexible trading account, giving you freedom to develop your portfolio in whatever way works for you.

Before you start with a Investment Dealing Account (IDA) have you used your annual ISA limit yet? It usually makes sense to do this first since an ISA shelters your savings from tax.

There are no tax advantages to investing through a IDA, but because of this you can invest as much as you like, and have as many IDAs as you like (paying an Account fee for each) – helpful if you’re saving towards different goals.

You are in control:

No savings limit

Access your money any time

Hold an IDA jointly with others

Charities, clubs and companies can hold a IDA

The tax you pay depends on the investments you hold and your personal circumstances

Unlike an ISA a Investment Dealing Account (IDA) does not shelter your investments from Income or Capital Gains Tax. Remember the value of your investments and any income from them can go down as well as up and you may get less than the amount you invested. All investments carry an element of risk which may differ significantly. Tax rules may change in the future and taxation will depend on your personal circumstances. If you are unsure as to the suitability of any particular investment, you should speak to a Financial Adviser. Laws and tax rules may change in the future without notice. The information here is our understanding in April 2018.

Is it right for me?

  • Used ISA limit for current tax year
  • Looking to invest from a range of investments including funds, investment trusts, ETFs and equities
  • Willing to view these as medium to long term investments (5 years or more)
  • Comfortable paying Income Tax and Capital Gains Tax on your investments

FAQs and resources

What is an IDA

What is an IDA?

An IDA or Investment Dealing Account is a flexible dealing account that lets you hold a variety of investments. It gives you complete control to develop your investment portfolio in a way that works for you.

Are there any tax advantages to an IDA?

No, but there are no investment limits either.

Opening an IDA

Who can apply?

If you are 18 or over and resident in the UK you can apply for a IDA. Charities, clubs and companies can also open a IDA.

Do you accept applications from the US?

We don’t accept applications by or on behalf of any US persons.

How do I open an IDA Account?

The quickest and easiest way to open an IDA with us is online using our secure service. You can also apply by post by downloading our IDA application form or through your Financial Adviser.


How do I choose where to invest?

We can’t give you advice, but our Investing Hub is packed with research tools, ideas and information to help you when you’re making investment decisions.

If the fund you want to buy is not available, please let us know as we regularly review the funds we offer and make changes based on customer demand.

Paying In

What payment methods do you accept?

Debit card, direct debit (for regular payments) and cheque. We’ll send you a password and Personal ID to use on our secure online service, where you (or your adviser) can manage your account, including the payments you make.

You can also set up regular monthly or quarterly payments online by direct at any time. Or by sending us an IDA instructions form.

Transferring In

Can I transfer other IDAs to ATS?

Yes, you can transfer investments from elsewhere to us without selling them first so long as we offer them through our Investment Dealing Account. We charge flat Account fees that don’t grow with your investments, making our charges very competitive for larger investment pots.

Your current provider might charge you for transferring.


What are the charges?

We charge flat Account fees for our platform services. These are made up of monthly account fees to cover the basic ongoing cost to us of managing an account for you and charges for other services you may ask us to provide - buying and selling investments for example and if you invest directly with us or through a Financial Adviser.

See our charges section for more information.

Keeping Track

How often will I get valuation and statements?

Four times a year and you’ll be able to check the current value of your IDA online at any time


Do you help with information for my tax return?

Yes. At the end of each tax year we’ll send you a tax certificate. This details any tax-relevant income payments received into your Investment Dealing Account during that tax year and you can use it as evidence of these with HMRC.
