What are the main differences between a business run by a sole trader or partnership and a company managed by its director/shareholders?

This is a freeview 'At a glance' guide.

This comparison is for a trading business. Many of the points summarised here are not relevant if you want to compare individuals or companies managing investment businesses.

Sole trader or partnership

Limited company: you are director & shareholder

You are the business.

The business is a separate legal entity to it's shareholders and directors.

You are the owner.

You are a shareholder; you hold all or part of the company's share capital.

You are the manager or proprietor.

You serve the company as its officer as a director (a company secretary is an officer too).

In the event of any legal dispute, you will be sued personally unless you have suitable insurance. You should read the small print on any insurance policy very carefully.

If you are in business with someone you can run the business via a Limited Liability Partnership (LLP) to protect yourself from personal liability. Partners can be jointly liable for certain acts of the LLP which can result in personal bankruptcy. 

In the event of any legal dispute, the company will be sued, not its owners.

Owners or directors may be held personally liable for a company's wrongdoing in some situations. e.g:

  • In general law, where the director has perpetrated fraud.
  • Where the director has committed specific offences such as corporate manslaughter, or under health and safety, environmental acts, companies acts and listing rules.
  • In cases of fraud or deliberate behaviour of the directors to avoid tax and for penalties involving deliberate concealment.
  • For offences by Senior Accounting Officers of large companies.

Employment status

  • You are self-employed; you cannot be your own employee.
  • In difficult times, such as the COVID-19 pandemic as you are self-employed government support is likely to be based on your trading profits.
  • Members of a Limited Liability Partnership on fixed profit /no risk arrangements may be automatically classed as employees.

See Salaried members' rules

 

Employment status

  • A director is an office holder, this does not automatically make you an employee for employment law, the National Minimum Wage or Tax Credits.
  • For Income Tax and National Insurance company officers are treated as employees.
  • During the COVID-19 pandemic government support was based on payroll salary.
  • If the Off-Payroll Working rules apply, fees paid to the company, in respect of personal services supplied by the company to its end client are taxed under PAYE/NIC by the end client. The worker (generally the company owner) is treated for tax as if being employed directly by the end client. No extra employment rights are created. 

See Employment status: Directors

Tax on profits

  • You pay Class 2 & 4 National Insurance and Income Tax on the taxable profits of your business, or your share of profits if you are in partnership.
