Is there an IR35 test?
In short yes. There is a “CEST” tool provided by HMRC that allows contractors to check their employment status for tax however this has been widely criticised for being too closed minded in scope.
It’s therefore important to not only take that test but review your working practices yourself.
As a general rule, IR35 looks at three main pillars of your working practices:
Control – What level of control does your client have over what, how and when you do your work. For example, does your end client require you to work in a team, manage or be managed, book in your holidays or wear a uniform? In reality a contractor should be free to operate as they wish, but if your client requires you to act like an employee then the chances are you’ll be caught by IR35.
Substitution – A key focus for IR35 is the ability to send anyone to fulfil a contract. As an employee you can’t ask someone else to go into work for you, but as a contractor you should be able to send any qualified person to do your role if you can’t make it.
Mutuality of Obligation – As an employee your employer is obliged to find work for you to do and for you to accept it. As a contractor, your client shouldn’t have to find work for you to do if there isn’t any.
The most common industry for contractors to fall foul of IR35 is in the NHS because it is tightly controlled, substitution is rare and mutuality of obligation is clear. As an example:
A nurse in the NHS will book holidays, work according to a rota, wear a uniform, fall under a line manager, be unable to send someone else to do their job and have to treat the patients put before them.
In reality then, contracted nurses in the NHS will fall foul of IR35 as they are defacto employees.
In contrast an IT Consultant for a bank:
Will work whenever they want, can work from home, will often wear their own clothes, can choose from several projects and can hire in extra consultants to fulfil parts of their contract they are unable to do.
A contractor with a role as described above should fall outside of IR35.
