The attraction of limited companies goes back a long way, ever since the Law Lords heard the case of Salomon v Salomon & Co [1897] AC 22. This was the defining case, which established the fact that a corporate personality is a separate legal person to its members. Mr Salomon was a leather merchant. In 1892 he formed a limited company with his wife, five of his children and Mr Salomon himself making up the seven shareholders (the statutory minimum in the 19th century). He sold the business to the company and used the proceeds to pay off the trade creditors. The proceeds included debentures secured on the business, which were taken by Mr Salomon.
Unfortunately, the business did not prosper as expected and Mr Salomon was forced to sell his debentures to try to save the business. This was insufficient and the company went into insolvent liquidation. The liquidator alleged that the company was a ‘sham’. The Court of Appeal held that the shareholders should have been a bona fide association, not just seven members of the family in what was effectively a one-man company. The House of Lords disagreed and one-man companies have been with us ever since.
The Finance Act 1972 was instrumental in the explosion in demand for these companies. Suspecting widespread tax evasion in the construction industry, the Treasury produced legislation requiring building contractors to deduct tax before paying sub-contractors, unless they were dealing with a company, when the company could be paid gross.
Shortly afterwards, legislation was introduced in respect of temporary workers, so that they would be treated as employees of the agency ‘employing’ them, unless the agency was contracting with a limited company. Agencies in both construction and other industries preferred not to bother with numerous ‘employees’ starting and leaving and it became almost impossible for an individual to find employment through an agency, other than by working through a limited company.
The attraction was increased by Finance Act 2002, which imposed a starting rate of corporation tax of 0% (previously 10%) for companies whose profits were not more than £10,000. This continued until 2005, when it was abolished.
Against this background, the 1999 Budget Press Release IR35 proposed Intermediaries Legislation designed to prevent individuals avoiding tax and National Insurance through the use of companies. It came into effect from 6 April 2000 and continues to be known as IR35.
However, there remain advantages to trading through a limited company:
- a contractor can draw a minimum salary and pay the minimum tax and National Insurance, drawing profits as dividend out of post-tax profits of the company; there is no further tax on the distribution, except where the contractor has a liability to higher rate tax;
- this gives rise to a National Insurance saving (no NI on dividends) and a cash flow advantage, since dividends do not attract PAYE;
- the rate of corporation tax is substantially lower than the total of income tax and National Insurance;
- for contractors such as IT and other professionals, there is the opportunity to work from home. This can give rise to substantial cost savings (see below);
- agencies engaging contractors are saved the cost of employer’s National Insurance.
The aim of IR35 is to seek to prevent contractors avoiding tax and National Insurance by treating them as employees for tax purposes. They do not, however, have the benefits due to employees under employment law, such as sickness benefit, holiday pay, maternity benefit etc.
IR35 tests for employment are different for income tax and National Insurance and may yield different results for the same purpose.
