This note discusses the introduction in April 2000 of 'IR35' - legislation to tackle the exploitation of personal service companies as a means to avoid tax.Jump to full report >>
In the 1999 Budget the Labour Government announced that new rules would be introduced in the tax treatment of personal service companies (PSCs), to prevent the exploitation of this corporate structure as a means to avoid tax. These rules are usually called IR35, after the number of the Budget press notice which covered this change. Individuals working in a number of fields - Information Technology (IT) in particular - often set themselves up as a PSC, providing their services as a consultant to a client, rather than, say, working directly for that client on their payroll as their employee. The client pays the service company for the work they have done, without deducting income tax or National Insurance contributions (NICs) under PAYE.
There are several potential tax advantages to this type of arrangement: first, the range of expenses which the PSC may set against its taxable profits will be much wider than that allowed an employee to set against his taxable income. Second, there will be a cashflow benefit in avoiding tax being deducted at source each month. Third, the individual may be in a position to receive dividends out of their service company, as an alternative to only being paid a salary, an arrangement which is likely to mitigate their liability to NICs.
Following a long and contentious consultation exercise, provisions were introduced in the Finance Act 2000, and came into effect from 6 April 2000. In brief, the off-payroll working rules cover any engagement where an individual provides services under a contract between a client and an intermediary and, but for the presence of the intermediary, that person would be considered the client’s employee for tax purposes. In these cases, the intermediary is required to account for tax on the payment made by the client in the same way as employee earnings.
This note gives some background to the use of personal service companies to avoid tax, before discussing the introduction of IR35 and its first years of operation.
Although IR35 has remained controversial in the twenty years since it was first announced, and many stakeholders have made the case for the regime to be scrapped, the rules have remained on the statute books. In the 2016 Budget the then Chancellor George Osborne announced that from April 2017 public sector bodies would have new duty to ensure any contractors that they took on were complying with IR35. At the time Ministers ruled out introducing a similar duty on the private sector, but the Autumn 2017 Budget noted that in 2018 the Government would “carefully consult on how to tackle non-compliance in the private sector, drawing on the experience of the public sector reforms.” A consultation was launched on 18 May; the deadline for responses is 10 August. A second note discusses these developments.
