A sole-trader or a LTD company are the two most popular methods of doing business in the UK – but which type is the right choice for you. In this article we can help you decide!

A sole-trader in the UK

Being self-employed (sole-trader) in the UK requires you to have a National Insurance Number (NIN) and an address in the UK. It is a simpler form of enterprise and common business examples include: restaurants, barbers/hairdressers, plumbers and electricians.

Sole-traders don’t pay corporation tax like LTDs do, but instead pay income tax and national insurance, depending on how much profit they make. Income tax is applied when your profit or your wage is above £12,500 per year.

Sole-traders must also pay national insurance in either class 2 or class 4 brackets, but you do not need to pay NI contributions until your profits exceed £6,205.

Class 2 NI – For profits above £6,365. Payment of £3 a week

Class 4 NI – For profits above £8,632. 9% on profits between £8,632 and £50,000 and 2% on profits over £50,000

How to register as a sole-trader

Registering as a sole-trader is simple procedure and involves informing HMRC that you are self-employed and that you need to pay tax through self assessment. The process involves registering for class 2/4 NIC and for self assessment.This can be done on the GOV website portal. 

As a sole-trader you will have many responsibilities including:

  • Keeping up to date records of the company’s revenue and expenses
  • Providing your annual tax self assessment to HMRC
  • Working out how much income tax and NI you need to pay (there is an online calculator on the GOV website).
  • Repayment of the company’s debts yourself
  • Registering on the Construction Industry Scheme, if you’re planning on operating in construction

Advantages of being a sole-trader

  • Simple accounting
  • Generous allowance for tax free income
  • Small contributions to national insurance
  • Privacy for your business, no information has to be given at the Companies House. Could possibility be a disadvantage (depending on how you operate) as there will be no public record of your business and some companies may avoid doing business with you.
  • No need or obligation to pay corporation tax
  • Possibility for retirement in the UK with state pension

Disadvantages of being a sole-trader

  • Liability! As a sole-trader you have unlimited liability, as your business is not a separate legal entity. This means you bear full responsibility for company debts. In the worst case scenario your assets could be seized to cover debts that you couldn’t pay (could be your house, car or even your computer).
  • Complex procedure when you want to sell the business, as only the assets can be transferred and the buying entity must form its own business structure.
  • Needing to be present in the UK for most of the year (at least 183 days), so you can be a British tax resident.

A LTD company in the UK (Limited Company)

A Limited Company, also known as a private limited company or a limited liability company in other jurisdictions. A LTD company is most commonly ‘limited’ by its shares, which means shareholder(s) are only liable to pay potential creditors against the original capital invested. Your assets outside the the company are safe because the company exists as a separate legal entity. Running a LTD company means you can be the sole shareholder and appoint yourself as the director.

Advantages of setting up and running a LTD company

Savings in taxes and a large tax free amount

If you’re the sole director and shareholder in your company, then you can set your salary as you please! The income tax free allowance is 12,500 GBP/year, so paying yourself a wage up to this value will stop you from paying income tax. In the UK if you earn a wage lower than 8424 GBP/year, you will not pay any income taxes or national insurance <see UK income and corporation tax>. In your LTD company you can employ up to 3 directors. This allows a withdrawal from the company of 25,272 GBP/year without any tax or insurance deductions. Even with revenues above this amount, your LTD will still be financially viable in the UK (even with addition of corporation and income taxes).

Smooth and simple running of your business

There is no time wasted each month on bureaucratic procedures, like there is in many other countries. Once your company is registered in the UK, you can send us invoices that are issued/ received by your company. We can represent your business and take care of all your tax and accounting needs. Tax audits in the UK are fairly rare and only happen when HMRC suspects something is wrong with your company tax returns. Even if this does happen, the procedure will likely be a phone call, which can be done with you or your accountant. HMRC doesn’t have the resources to systematically audit every UK business.

A British state pension

As a director of a LTD in the UK, you will have right to receive a British pension. This amount will vary depending on how many years you work whilst contributing to national insurance. The minimum you can receive is about £48.17 per week after 10 qualifying years and the maximum is £168.60/week, which requires 35 years of work. To work out what pension you might receive, take the max at £168.60 and divide it by 35, then multiply it by the number of qualifying years you have been working (running your company and paying NI contributions). Note, qualifying years are gained when you’re employed and earning more than £166 per week (£8,632/year).

Disadvantages of a LTD company

The main disadvantage of operating as a LTD is that you will have to pay corporation tax on any profits you make. This could neutralize the savings you made on income tax. To avoid this many companies use their all their revenue to pay director salaries.

LTDs and sole-traders – Summary

Operating as a sole-trader requires you to have a presence in the UK of at least 183 days/year. You must have a UK address and be a British tax resident. Running your business as a LTD only requires the tax residence to be located in the UK.

National insurance contributions have to paid as soon as your sole-trader company starts receiving income greater than £6,365/annum, but these are however very small payments (£3/week). LTD NI payments are actually greater than sole-traders at higher revenues. LTDs are also obliged to pay corporation tax on their profits, but many companies avoid this by paying all income in the form of directors’ salaries.

As a sole-trader you have unlimited liability and accept full responsibility for all the debts incurred by the company, while in a LTD you can only be responsible as a shareholder for the amount originally invested into the company (limited liability).

Investing, selling or dividing a LTD is much simpler as well, due to the company being made of shares. The shares facilitate the process of allowing other individuals into the company, to accelerate development e.g. investors.

Sole-trader businesses are very commonly set up by individuals living in the UK but a LTD can be profitable whether you live the UK or elsewhere.
