Why use a corporate share dealing account?

A corporate share dealing account, or sometimes called a business share dealing account, is great for a company with lots of spare cash but can’t invest in their own business to grow the business further.

When excess cash begins to pile up in the business bank account it could be invested in the stock market for the potential to make a much larger return than the little bit of interest it makes from just sitting there in the bank account.

It’s a great position to be in, so congratulations on building a successful business that generates lots of profit and positive cash flow!

Why not take the money out of the business?

You might be thinking, why don’t I take the money out of the business and invest the money personally? It’s a great question, and you can definitely do that! 

The drawback is you’ll have to pay income tax if you take the money out as a salary, and then pay National Insurance Contributions too, both as an employer and an employee.

Taking money out of a business

If you take money out of your business as dividends (which is giving your profits back to the owners of the business), you have an allowance of £2,000 where no tax is paid, but then you’ll have to pay income tax on the rest (that’s a tax on your earnings, that everyone pays).

So effectively, you’ll be paying at least 20% of whatever you take out of the business in tax (the basic rate level of tax). That’s presuming you are already paying yourself a salary, and so have used up your personal allowance (that’s the bit where you don’t need to pay tax, currently £12,570).

If you begin paying yourself over £50,270, you’ll have to pay 40% tax (higher rate tax), and over £150,000, it’s 45% (additional rate tax). That’s quite a lot of your profit gone on tax if so!

To avoid paying income tax, at least immediately, you can invest your company’s profits before you have to pay income tax yourself – which can mean your money grows much faster, thanks to compound interest – that’s when the money you make, begins making you money too. So that 20% tax (or even 40/45%) can have a big impact.

Your business would still pay Corporation Tax, which is a tax on profits, and 19%.

What about using an ISA?

When you take money out of the business (and pay tax), and then invest in your own name, it’s a good idea to invest using a Stocks and Shares ISA – an account where everything you make is tax-free! (an ISA stands for Individual Savings Account).

ISA (Individual Savings Account)

However, you might have saved as much as you are allowed each year into your ISA (your £20,000 ISA allowance). And so, if you wanted to invest more than this, you’d have to invest inside a General Investment Account (GIA). This means you’d be liable to pay Capital Gains Tax, which is 20%, if you made a profit of over £12,300 within a tax year (April 6th to April 5th) from your investments (when you sell the investments).

ISA allowance

Keeping cash inside your limited company would mean you can avoid paying Capital Gains Tax yourself in the future. Although it’s often a good idea to use your Stocks & Shares ISA first, as you won’t be paying Capital Gains Tax anyway.

What about using a pension?

Investing in your own pension is a great idea – you’ll benefit from tax-free saving when you add money into your pension, and benefit from not paying Capital Gains Tax when your pension grows.

If you’re self-employed as a company director (the owner of a company), you’ll have to arrange your own pension, rather than your employer arranging this for you if you were employed. 

Everytime you contribute money to your pension, the government will top it up by 25% (which is effectively a refund of the amount of income tax you’ve paid). And if you are a higher rate tax payer, or additional rate taxpayer, you can claim the amount back you’ve paid at those rates on your Self Assessment tax return (it’s easy to do).

Pension tax relief

Your pension can act exactly the same way as an ISA or a share dealing accounts for limited companies. You just need to open a self-investment personal pension (SIPP) if you want to make your own investment decisions. Or you could even let experts just handle everything for you – such as with PensionBee). 

If you haven’t got a pension yet, it’s easy to do, and we’ve got the best private pension providers in the UK, to find the best one for you. You could also check out the best investment platforms UK.

You can invest as much as your earnings into your pension, so a maximum of your salary if you are employed by your business, plus however much you take out of the business for yourself (e.g. dividends). There’s an upper limit of £40,000 however. Well, you can add more, but you’ll have to pay extra taxes, so it’s normally not worth it.

Pension annual allowance

If you haven’t got a pension at all, it’s probably worth considering taking money out of your business and investing the money in your own pension before investing the cash within the business name – the tax-free benefits are pretty great!

What’s a limited company?

When a business begins operating (which is called trading), there are a few options for how the official structure of the business works in law. 

The owner could run it entirely in their own name, which is called a sole trader, or if there’s multiple owners that are effectively offering their services rather than trading, like a law firm, they could form a partnership and be recognised legally as such.

Or, the owner(s) could register as an official company – and the company would be recognised legally, rather than the owners themselves. This is called a limited company. 

It has the word ‘limited’ in it because it has ‘limited liability’ status, which means that the company, not the owners, is responsible for any financial losses (if the business makes any). In effect, it is completely separate from the owners – in fact, many companies go on to thrive after the person who set it up leaves or retires.

What’s a Legal Entity Identifier (LEI) number?

When you want to buy and sell investments with your limited company, you’ll need an LEI number. This is a unique code for your business, which is public, and it’s 20 characters long made up of letters and numbers.

The code contains information about your company’s ownership, such as who owns it – and so makes financial transactions (such as buying investments) completely transparent. It works globally too. You can learn more on the GLEIF website.

Legal Entity Identifier number

To clarify, you’ll need one to make investments, whatever company you decide to use to make investments. And if you use one of our recommended share dealing platforms, like InvestEngine, they’ll create one for you. However, it’s not necessarily free (although the first year is free with InvestEngine). Expect to pay around £70 per year if you were to arrange it directly yourself.

That’s it

It’s pretty straightforward investing with your limited company in a share dealing account – in fact, it’s exactly the same as investing personally. The only difference is you’ll have to jump through a few more hoops when you first get started and open your account (such as getting an LEI number).

Good luck investing! And if you’re looking for a new investment platform, here’s the best platforms in the UK.
