Interactive Brokers: Limited Company Investment Account

This is a review of the popular Interactive Brokers investment platform. Interactive Brokers allow UK limited companies to open a company account. This is great news as more and more platforms allow LTD companies to invest in stocks & shares, mutual funds, ETFs, Forex, Options etc.

I opened an account with IB after a lot of readers pointed out the platform benefits to me. Interactive Brokers are a well-known American firm who now operate in the UK too. I like the transparency and the fact that they’re listed on the stock exchange (NASDAQ: IBKR).

Companies that trade publicly means higher regulation and better protection to us, the customers. Customer money sits in a segregated account, as expected. Read more about how investors are protected here.

In my previous article, I demonstrated how to invest your company profits. A lot of people have done so through different brokers. I initially trusted Interactive Investors for my funds, but I have now switched to Interactive Brokers which is a low cost and trustworthy broker, in my opinion. Things I’m looking for in an investment platform are:

  • Low cost
  • Decent customer service
  • Solid coverage of the ETF universe
  • Strong reputation
  • Support for Limited Company accounts

It’s worth noting that Interactive Brokers only offer a limited selection of mutual funds for non-US investors. Initially, I thought this is a blocker, but then I remembered most of the index funds can be replaced with their ETF counterpart (or similar). They offer a huge selection of ETFs including those domiciled in the UK, US, Luxembourg, Ireland etc.

For example, Vanguard’s World VWRL ETF is a global stock market ETF. Then ETFs are great because they can be traded instantly, have tax advantages and are low cost too. So that’s covered for me.

Interactive Brokers are an advanced platform for professional traders. They offer stocks, ETFs, CFDs, Metals, Options, Futures and Forex among other options. For example, a major feature that took my attention is margin trading. This means you borrow money to invest. You pay some margin fees and have the option to invest more than you can.

They also offer a nice API if you want to do some algorithmic trading.

However, this does not mean IB cannot serve someone like myself – looking for a simple solution who just wants to invest 5-6 times throughout a year in a few tracker funds. I just like to keep it simple, but there are plenty of options to make it complex if that’s what you want.

Fees – Pricing

I’m not going to explain the whole range of fees as this depends on the country, order value, type of product etc. But I’m going to give you a brief overview of a small business account that places a few trades each year into stocks & ETFs in the UK which is one typical use case.

Interactive Brokers is really cheap compared to other brokers. They have both fixed fees and tiered solutions. You can choose which one you want to use.

ETFs and Stocks (Fixed fee)

Up to £50,000 GBP trade value – £6.00 per order

Then depending on the activity of the account, you pay a small fee if you don’t generate enough commissions.

Monthly Activity Fee = 0 if monthly commissions are equal to or greater than USD 10. (or currency equivalent)
If monthly commissions are less than USD 10,
Standard Activity Fee = USD 10 – commissions.

So for an account that places one ETF trade a month, the annual total charge would be
Trade commissions: £6.00 * 12 months = £72.00
Inactivity fee = (£10.00 – £6.00) * 12 months = £48.00
Total annual fee = £120.00

In my experience, this is a very low commission for a corporate account.

ETFs and Stocks (Tiered fee)

The IB pricing structure pleasantly surprised me. Their tiered trading fee starts from 0.050%, min £1.00 per trade for up to £40 million monthly trading volume.

The tiered fee is a great solution for those that want to place small trades a few times per month. Basically the break-even point is an average of £12,000 per trade above which it’s probably worth paying a fixed fee instead.

So a trade of £10,000 at 0.050% will cost £5.00. Even better, a trade of £1,000 will cost only £1. This is amazingly low. Sure you still have to pay a monthly activity fee but still. Assuming you place 10 x £1,000.00 trades each month, so in 12 months that’s 120 trades.

Total annual cost = £120.00.

I cannot stress how low this is compared to the typical £12.50 per trade of other brokers. Other brokers would charge £1,500 per year in trade expenses alone for a similar scenario.

How to open an Interactive Brokers limited company investment account

Opening a UK limited company account is not the easiest task but it’s all online and certainly doable within an hour or so. You will need to fill in certain company and personal information and upload documents to verify your details.

I won’t go into details of each and every screen, because most of them are straightforward. I’ll only explain the bits I found tricky.

There are 3 types of account for small businesses:

  • Cash account
  • Margin account
  • Portfolio Margin account

The main difference between Cash and the other two types of accounts are the ability to trade on margin. This means you can trade with borrowed funds. It also means you can lose more than your initial investment so beware.

Margin account requirements are rules-based whereas Portfolio Margin account requirements are risk-based according to the positions in your portfolio.

I opted for a Margin account. I do not plan to trade on margin anytime soon but would like the option to be able to do so in the future. Read this document from IB that explains what the margin benefits are along with their requirements.

Interactive brokers account type

Note: You can upgrade your Cash account to a Margin account later.

My company is just a vehicle for me to invest in stocks, shares and property. It does not really trade, but invest for the long term. This may or may not be the case for you.

The trickiest part of the application will probably be the one where you select your FATCA status. Luckily for me, I had to do it again for Vanguard in the past, therefore I was familiar with it. But it can be very confusing for people and brokers are not able to help either.

How to determine your FATCA status

The Foreign Account Tax Compliance Act (FATCA) is a 2010 United States federal law requiring all non-U.S. foreign financial institutions (FFIs) to search their records for customers with indicia of a connection to the U.S., including indications in records of birth or prior residency in the U.S., or the like, and to report the assets and identities of such persons to the U.S. Department of the Treasury.
Source: Wikipedia

Declare your FATCA classification

If you’re a UK-based LTD company you’re probably either an Active or a Passive Non-Financial Foreign Entity (NFFE), unless you’re a bank, pension trust or a public company. What “Foreign” really means is foreign from a US standpoint, as this is a US legislation.

From the IRS instructions (w8ben-e form), an Active NFFE is one that:
• Less than 50% of such entity’s gross income for the preceding calendar year is passive income; and
• Less than 50% of the assets held by such entity are assets that produce or are held for the production of passive income (calculated as a weighted average of the percentage of passive assets measured quarterly)

I’ve stumbled upon a very helpful FATCA decision tree by OneAccount and here’s its glossary. And here’s the long HMRC guidance notes PDF, if you want to kill some time.

My company is a Passive NFFE but that may not be the case for you. If you invest through the company you also trade with, this may not be the case for example. Or if you use your investment company to buy and sell regularly (trading).

Again, I’m not sure about this and you’ll be better off calling HMRC (0300 200 3500) to double-check your company is a passive or active NFFE. And as always, seek professional advice.

How to complete the W8-BEN-E Form for a UK investment company

This is another step in the process. Interactive Brokers will give you a W8-BEN-E form for you to fill out online. The W8-BEN-E form is the equivalent of the W8-BEN form but for corporations. This tells IRS that they should only withhold 15% tax off your dividends rather than 30% thanks to the USA-UK tax treaty. If you have an ISA and invest in US companies, you’ve probably completed one already.

I’ve ticked Part I (1,2,4, 5 – Passive NFFE, 6, 8b – that’s your corp tax UTR), Part III (yes, 14a, 14b – Company that meets the ownership and base erosion test – see IRS instructions), Part XXVI (ticked 40a, 40b).

I can always electronically submit a new WB-BEN-E form if my circumstances change. On the Classic AM interface, it’s under Manage Account -> Account Information -> Tax Information -> Tax Forms.


Documents upload

The most time-consuming step of the onboarding application is the Documents Upload screen. Click on the More Information links to find out what each one means.

Documents upload screen
Upload documents for verification

It takes time to download, sign and upload lots of forms. But the good thing is that you can download all of them locally, and use Adobe PDF reader to Fill & Sign. You don’t really need to print it and send letters, unlike other brokers.

The documents you will usually need are:

  • Business Bank statement
  • Certificate of incorporation (you can find this on Companies House)
  • Personal ID (passport, driver’s license)
  • Proof of address (utility bill)
  • A few forms from “More Information” you need to download and sign

I only uploaded a few documents and left it incomplete for the night. The next day I received an e-mail from the New Accounts department asking me for a few more details including the Source of Funds. This was a good sign of customer service. I provided all remaining details and they opened my account the same day.

After signing up, you will be asked to electronically submit your EMIR and MiFir preferences. These are regulations for the derivatives markets. I do not trade derivatives and therefore these don’t apply to me. However, if you do, you may be subject to these regulations.

If you want to ask any questions during onboarding, a useful e-mail is [email protected].

Customer Service

The customer service has been pretty good so far. My account got locked after a few unsuccessful attempts to log in. I called them up and despite the late hours, they resolved it within minutes. I had to wait for less than a minute in the queue before a lady with a nice American accent picked up the phone. She was quite helpful and reset my password very quickly.

The customer service via e-mail was also decent. I had only uploaded a few documents during my onboarding. The next day I received an e-mail confirming that my documents were OK and the remaining documents they need from me to continue processing my application.

They have a live chat, a UK phone number, e-mail and a FAQ page.

Placing Orders on the Interactive Brokers platform

Personally, I like simple investing interfaces because I am a boring buy-and-hold passive investor. If I were a trader, the Interactive Brokers interface would be very appealing to me.

There are different ways to place an order, but I went for the QuickTrade online solution. As the name suggests, you can buy and sell any security at Market or Limit price and get on with life. Here’s how the interface looks like:

If you want more advanced features, then you can download the Trader Workstation which is a desktop application.

The Mutual fund – ETF replicator is another interesting tool this interface provides. Say you have an expensive mutual fund that you want to know what the alternatives are. This tool will show you what the closest options are in ETF flavour and at a lower cost.

Summary: Interactive Brokers Company Account

Interactive Brokers are a great platform for UK Limited companies wanting to invest their funds. It provides a wide selection of ETFs and other securities such as Options and Futures.

The ability to trade on margin should be carefully considered. It can go both ways…

The onboarding process is not the easiest, but it reflects the level of checks they need to perform to make sure they only have legit customers. On the plus side, you can do all of it online.

Interactive brokers are a public company which comes with both heavy regulation and transparency (both good for us).

36 thoughts on “Interactive Brokers: Limited Company Investment Account”

  1. I’m using Hargreaves & Lansdown since ii starting charging £30 per month! They have been fine so far. When I signed up, they insisted that I need an LEI even if I only want to trade funds, but on the plus side they accepted a digital bank statement.

    This seems a better deal though. If H&L give me any reason to switch then I will be checking out Interactive Brokers. Thanks for the heads-up!

  2. H&L have a £1.50 Regular Investment charge. If you used that for investing say once a month and one normal priced trade to sell, it works out just £28.50/yr

    I think your mixing you $ and £ with IB. You quote £6 trading fee but $10 inactivity fee, but then take one from the other as if same currency

    Inactivity fee is not charged if balance greater than $100k, equivalent to about £70k

    Two of the best things about IB is low FX fee $2 (£1.50 ish) and low US share commission fee (about 30p on tiered structure). Combining those makes a very low cost platform and opens up US share trading

    • Thanks, Cookie for the HL info. This looks very low. Am I right in thinking HL don’t offer US-domiciled ETFs/funds?

      On Interactive Brokers, I am not 100% sure how the inactivity fee is charged for accounts that trade in GBP (or another non-USD equivalent). Probably the $10 still holds for balances < $100k. So if we assume £6 is $8, then the monthly offering is even better than what I report. They probably only charge $2 per month in this case. I will correct it when I'm confident this is how non-USD accounts work. Indeed, the FX fee is really great!

      • H&L don’t offer US-domiciled ETFs, but neither do most brokers open to European citizens. IB doesn’t allow you to invest in US-domiciled ETFs either, unless you have been able too? Most ETFs that are available to Europeans and invest in US stocks are domiciled in Ireland or Luxembourg

        The US-domiciled ETFs, as their main market is US, don’t bother with KIIDs/KIDs and so are not available to Europeans. Shame as the fees are much less and more diversity

        • In IB you can actually trade US-domiciled funds. It’s just a bit of a hassle because you’ll have to manually convert your GBP to USD first. For dividend-paying funds, if you factor in the 15% dividend tax, it makes US funds a more expensive proposition overall, despite the European funds having higher OCFs.

          • Can you name or give the ticker of the US-domiciled funds you been able to purchase? Other sites have reported this was not possible, so be interesting to look at how this is done.

            Withholding tax is only on dividends and dividends are only a small percentage of the return, so would be interesting to see an worked example comparison

            The low $0.35 buying cost Vs £6 would need factoring in and $2 FX

          • Hi Cookie, I haven’t actually bought a US fund yet because if you factor in the dividend tax then it works out more expensive than the European equivalents. For example, the vanguard global small-cap fund (domiciled in Ireland) has a 0.29% OCF. A similar one would be a combination of VB (US only) and VSS (global ex-us).

            Ignoring FX fees and the spread:

            VSS costs 0.12% and yields 3.25%. 15% on 3.25 is 0.4875%. Total cost after taxes considered = 0.60%
            VB costs only 0.05% and yields 1.39%. If you factor in the 15% tax on its 1.39% yield, that’s 0.2085%. Total cost = 0.2585%.

            I guess the lower the yield the better if you want to purchase US funds. I will try to buy a few units of a US fund and report back here.

            By the way, the £6 buying cost only applies to the fixed pricing. You can go with tiered pricing and pay as little as £1 for each trade.

  3. Hi Micheal,

    It’s a great blog. I have opened the account with ii last month and they changed monthly fee as

    My Plan : 9.99
    Non Standard Account Fee : 29.99 for company accounts

    Total : 39.98/month.

    It is very costly hence just closed the account.

    Also opened IB account and but in the order screen when enter the Stock Symbol and click Go it is not showing any stocks.

    I will contact customer service to find out whats the problem with my account.

    Its Margin account and requested Options Trading as well.

  4. Yes, thanks for example, for dividends witholding tax is consideration

    I have found growth stocks beats dividend factoring in all returns. Haven’t looked at Corporation Tax saving

    Tiered commission LSE is % based, so less than £6 on less than £12k trades

      • Hey Michael,

        Valid point wrt retail investor. I believe there are no such restrictions for buying US-domiciled funds/ETFs/Shares via a limited company.

        Also, IB also has a Lite option, which is commission-free for US-based stocks (for Cookie’s growth stocks) and ETFs (general S&P 500 and world trackers). The FX risk has to be borne, of course, especially with the current GBP/USD setup.
        For Non-US funds/ETFs, the fixed-priced commission is applicable. Sadly, there is no low-fee regular investing option with IB

  5. FWIW another alternative is Selftrade. I’ve been using them for my company trading account since 2006, and can recommend them. I used them mainly for trading company shares, preference shares, bonds and some ETFs.

  6. Hi Michael,

    I bought stocks thru IB today and the process to buy USA stocks is below.

    1. Convert GBP to USD
    2. Buy USA Stocks.

    Just wondering, is this the case with other platform to buy USA stocks. If that’s the case we are relying on both GBP/USD and Stock performance to make profit.


  7. Hi Michael

    Thank you very much for the extremely useful information. I was wondering what your thoughts are about Hargreaves Lansdown account for investing through a limited company.

    I was wondering what ETFs and mutual funds you found worth investing on Interactive Brokers.

    I spoke with IB and understand that a margin will be applied automatically and there will be an interest charge on the loan. Is it better to have a Cash Account instead of a Margin Account for long-term investments to avoid the interest on the margin?

    Is converting currency to USD/EUR to buy ETFs and funds a good idea? Would you rather stick to the investment options available in GBP

    I would be grateful for your thoughts and advice

    Many Thanks

    • Hi Surban,

      I’m not sure about Hargreaves Lansdown as I have not used them personally. But I’ve heard other readers use them and they’re happy with the service.

      Regarding margins, I believe Interactive Brokers won’t charge you for a loan you haven’t taken. The option to take a margin loan is there. So they’ll show you the buying power, available cash etc. But unless you borrow money you won’t be charged –

      If you want to keep it simple, a Cash Account is better in that sense. I stick to GBP ETFs just because it’s simpler to buy, no need to exchange currency. But it doesn’t make a difference to the underlying NAV if they’re offered in other flavours.

      They have plenty of ETFs but no mutual funds. I use TrackInsight or Morningstar to search for ETFs. Personally, I stick to well-known ETFs such as VWRL (world equities), XDEV (value), WSML (small-cap), VEU, VAGP (bonds), etc These may or may not be suitable for you.

  8. Many thanks for the company hub and all the info on this website. I have set up a separate limited company to invest in index ETFs and opened up an account via Interactive brokers after using the info on this website. How did i respond to the question ” Make your EMIR election” on IBKR platform?

    I do have a LEI number though but if I provide this then it asks about Counterparty information
    Financial Counterparties (“FC”)
    Non-financial counterparties above the clearing threshold (“NFC+”)
    Non-financial counterparties below the clearing threshold (“NFC-“)
    Third country Entities outside the EU (“TCE”) in some limited circumstances

    Thanks for any info on this.

  9. HI Michael,

    Amazing article, thanks for this. I’m trying to sign up now with IB, I’ve setup a holdings company which I will transfer money into.

    Question: Any recommendations on a bank which operates holding company accounts? I tried signing up with Metro bank but they advised me saying they don’t open accounts for holding companies.


    • Hi Kunal, it’s a regular business account I have with Santander. Not sure if they have special rules for holding companies, but it was straightforward to open one for a regular limited company with an investment focus. I went to a business branch in London.

  10. Thank you very much, Michael. Much appreciated.

    I was wondering whether Accumulation ETFs are better if you like to reinvest as this takes away the hassle of physically reinvesting the dividends?
    Also, I gather VWRL dividend is paid in USD. Does it mean we need to convert it into GBP before we can reinvest the dividend into VWRL again?
    I see VWRP does this automatically as this is an accumulation ETF.

    Thank you for the list. Very helpful!
    Do we need USD to buy WSML?

    Many Thanks, Again.

    • Hey Surban, Accumulation ETFs take away the hassle of re-investing the dividends but add the hassle of calculating how much they paid you for accounting purposes. Pick your battles 🙂

      Indeed, investing in a USD-based fund means the dividends come in USD. WSML is a USD one. Interactive Brokers won’t automatically convert USD to GBP. This is why sometimes it’s better to stick with the equivalent GBP-based funds. What I’ve found useful, is that Interactive Brokers will give you all the ETF options (in different currencies) once you type the fund ticker, so you can pick the one you want.

      Hope that helps!

  11. Am I right in saying that the minimum investment in Vanguard funds on IB is $100k USD? My plan is to invest less than that in Vanguard LifeStrategy, so this is a bit of a deal breaker for me unfortunately.

    I’m finding it hard to find a platform for a corporate account at the moment. Hargreaves Lansdown are not currently accepting new company accounts due to Coronavirus, nor are Cavendish, Interactive Investor charge £39.99 a month, Fidelity are an option but have a postal sign up process, Share Centre are absurdly pricey. Vanguard seem to offer direct selling but I cannot find their fees anywhere on their website?

    Also, is an LEI an absolute requirement with every provider? I’m just a regular one man band private limited company with a few quid to invest. Not in the financial business.

    It’s certainly not as easy finding a corporate account as it is a personal one. I’d be grateful if anyone has any recommendations at this weird time?

    Great blog – thanks for all the helpful content.

    • The minimum investment in IB for Vanguard ETFs is very low, not $100k. I think LEI is a requirement, yes, but IB can do it on your behalf. Hope that helps, Pete.

      • Thanks Michael. I’ve been in touch with Joyce at IB and they have confirmed that unfortunately there is a minimum 100k USD investment in Vanguard LifeStrategy funds. This table shows the details:

        I suppose if I want to avoid this, I have to look for ETF equivalents. I will probably go for a Fidelity account instead, although they insist on being paid by cheque! I don’t even have a company cheque book any more since banking with Starling…

        • Oh sorry, Pete, I thought you were talking about Exchange Traded Funds, not mutual funds 🙂 But yeah, Lifestrategy funds don’t come in an ETF flavour as far as I know.

          Fidelity pay by cheque is so American! I hope you find an easy way… A friend started with Starling and they asked him to only deposit 10k at a time. Is it the same for you or has it changed? I’m with Santander and pay 7.50 a month.

          • Thanks Michael. Starling has been fantastic so far and I’d highly recommend them. There was no minimum deposit and there is no monthly fee. Always easily contacted and everything is done remotely with ease. Bouncing back loan took 24 hrs to get, super easy. I was paying HSBC £6.50 a month for very little and haven’t looked back since switching.

            Have spoken to Fidelity and apparently they can accept bank transfers but this involves another postal form. These post based platforms remind me of the 90s. Plan to change the fidelity account to Cavendish when they accepting business applications again, to get lower rates.



  12. Hey Michael,

    Did you look at TradeStation Global? They essentially are IB’s low cost option (i.e. they do not have a $10 per month charge), nearly everything else (charges, fund range etc.) is same as IB. Users essentially use IB’s platform but without the maintenance charges. Have you or anybody on this thread looked at TradeStation Global?

    • Thanks for the recommendation, Satya. I must admit I’ve never heard of TradeStation Global before. I see they charge 0.12% on each GBP and EUR trade, so you’d be paying £120 on a £100k trade. I wonder if they provide a fixed-fee option as IB do.

      Fees aside, how do you like TradeStation Global?

  13. Managed to set my IB account up. Was relatively simple, thanks to this article. I’m used to simple Vanguard FTSE Global all cap ACC investments in my ISA/SIPP. Is there a broadly equivalent ETF in IB?
