What is IR35?

The short answer

IR35 refers to rules introduced to ensure that long-term contractors were not avoiding payment of tax and National Insurance in situations where they were, in effect, employees rather than contractors. The rules can apply to sole traders and to those operating through their own limited company.

The longer answer

IR35 refers to the provisions of «Intermediaries legislation» introduced on 6th April 2000. Details of the legislation were first announced in the 1999 Budget press release numbered IR35. The legislation is now commonly referred to as ‘IR35’.

The aim of the Intermediaries legislation was to eliminate the avoidance of tax and National Insurance Contributions (NICs) through the use of intermediaries, such as service companies or partnerships, in circumstances where an individual worker would otherwise:

For tax purposes, be regarded as an employee of the client; and
For NICs purposes, be regarded as employed in employed earner’s employment by the client.

The impact of IR35

When you undertake a contract, you need to check that the provisions of the IR35 legislation will not apply. Broadly speaking, if the contract is such that, if you were to do the work directly for the client you would be seen as an employee, it may fall under the IR35 provisions.

Limited companies

If you are working through a limited company or partnership, you may be caught by the IR35 rules. Your accountant should be able to advise you on this.

Umbrella companies

Working through an umbrella company can help to avoid being caught by the IR35 rules. The umbrella company effectively employs you, and ensures that all your tax and national insurance contributions are met.
