You may have heard the term bandied around but what exactly is IR35? And why should I care? Well, if you are self-employed, or employ contractors of any sort, you are definitely going to need to invest some time investigating this term.  In recent times, the gig economy is amplifying the grey area that divides consultants from employees. Specifically, Great Britain has brought in IR35 to put a clear mark between the two.

At its core, the IR35 legislation is there for contract workers who operate as a limited company. For those working for a third party to provide specialist services to a client. It determines one as ‘outside IR35’ for these reasons, in addition to the stipulations that contractors do not receive benefits, holidays, or sick pay.

Why does the UK need IR35 legislation?

In general, the creation of the legislation was to stamp out the practice of companies having ‘disguised employees’ on their books in order to avoid tax. Contractors were often misusing the tax efficiency of a self-employment status, when in fact, their status should be as an employee. This became common as the gig economy opened these loopholes in the way we work. This is the government’s way of catching up with the changing world of work.

Why you should care about IR35

In addition to the legislation, HMRC is actively investigating individuals and companies to determine if a consultant’s status is correctly ‘outside IR35’. If not, the new rules demand that any money an employer hasn’t paid in national insurance be rectified. Also, missed tax and interest on the tax need to be paid. That’s not to mention the penalties for misclassifying yourself, which can be enormous.

For clarification, HMRC has developed an online employment status tool (CEST) for contractors unsure of their liability under IR35. If you are receiving the same rights as that of a permanent employee, for example, holiday entitlement, sick pay, or if you are receiving certain benefits, you will likely be deemed as inside IR35. We have a handy article here on determining whether you are inside or outside IR35.


This isn’t something you want to get wrong. Taxes are not an area you want to mess around with. Get your status properly assessed so you can get on with business.
