IR35 - Background and Contents

Background and Contents

In 1999, as part of that year’s Budget, the UK’s Chancellor of the Exchequer, Gordon Brown, announced that measures would be introduced to counter tax avoidance by the use of so-called personal service companies. Properly known as the “intermediaries legislation”, it is more commonly referred to by the consecutively numbered Inland Revenue (now HMRC) budget press release number 35 in which it was announced (i.e. the 35th press release of that year), titled IR35: Countering Avoidance in the Provision of Personal Services. The press release was issued on 9 March 1999, the same day as the Chancellor of the Exchequer's budget statement.

It came into force throughout the UK in April 2000. Although it was part of that year's Finance Act and was not law at the start of the Financial Year, the Act backdated its commencement to April 6, 2000. The legislation has been consolidated in the Income Tax (Earnings and Pensions) Act 2003 and in the Statutory Instrument Social Security Contributions (Intermediaries) Regulations 2000, SI 2000/727.

Historically, it had been advantageous for the owners of a small company to take all of their wages in one month, thereby only incurring NI contributions once (up to the monthly ceiling) instead of paying a regular contribution every month like most employees. This ploy had been circumvented some years prior to the introduction of IR35 by imposing NI on the total annual income of directors as if it were spread over the year, even if only paid by one payment. The increased usage of dividend payments instead of wages was partly a reaction to this change. An additional sense of grievance felt by those who were driven to incorporate, for whatever reason, was the large disparity between the National Insurance burden on companies and employees (>20% if the employer's contribution is included) and that imposed on the self-employed.

The stated aim of the measure was to prevent workers from setting up limited companies via which they would work effectively as employees, but saving on tax. The so-called “Friday to Monday” scenario, that it was possible for a worker to leave a job on Friday and return on Monday to be doing the same work for the same company, but, as a contractor via their own limited company paying a lot less tax, was cited in the press release as the anomaly being corrected. In such a scenario, HM Revenue and Customs would be allowed to “look through” the contractual arrangement between the worker’s company and the client company and to formulate a “hypothetical contract” which showed that the worker was a “disguised employee”. The fee paid to the worker’s company would then be taxed as a salary. Normal employment status rules should be applied when considering IR35 status and the view of HM Revenue and Customs can be successfully challenged.
