Why do clients get to decide my IR35 status?

How do clients assess IR35 status?

There isn’t one single method of determining whether an engagement is inside IR35 or not. The off-payroll working rules (the ones that make clients responsible for deciding if IR35 applies) only say that clients must take “reasonable care” when assessing the status of a worker.

In practice, this typically involves methods such as:

  • Using HMRC’s ‘Check Employment Status for Tax’ (CEST) online tool
  • Engaging a specialist consultancy or legal expert to conduct an assessment
  • Using software or digital questionnaires provided by a specialist consultancy or legal expert
  • Conducting the assessment in-house without using software or tools
  • Advertising the role as ‘inside IR35’ – also known as a ‘role based determination’

     

What is CEST?

To help clients to make determinations, the government hosts a free-to-use tool named ‘Check Employment Status for Tax’ (CEST). CEST asks a series of questions and generates a status decision based on the answers provided.

While CEST primarily exists for clients, it can be used by anyone, including contractors. It’s entirely anonymous – you don’t have to put your name or company name into it, and HMRC keep no record of it. If you use it and it provides you with a result which says ‘IR35 does not apply’, keep it and share it with your client – it may help them get their own assessment right.

What does 'inside IR35' mean?

Being ‘inside IR35’ means that a freelancer or worker is a ‘deemed employee’ for tax purposes. However, this doesn’t mean that they become directly employed by the business they are working for.

Instead, the worker may be asked to join another payroll – this could be an agency payroll if an agency is involved in the work placement, or an umbrella company payroll.

For IR35 to apply, it must be determined that the relationship between a freelancer and their client is one ‘of service’ rather than ‘for services’. These terms are used in case law. A contract ‘of service’ is akin to an employment; a contract ‘for services’ indicates a genuine freelance engagement. The distinction is made by referring to a number of ‘tests’, which, are established in case law.

Complete the CEST tool. If it determines that IR35 doesn’t apply, show the result to your client. If CEST doesn’t put you outside IR35, don’t worry – its anonymous and you don’t have to share it with anyone.
If you disagree with your client’s determination you can dispute it. Again, show them any evidence you have that IR35 doesn’t apply.
An inside IR35 determination may provide an opportunity to negotiate an increase in your day rate. If your client wants you on the project, they may be prepared to ease the burden by paying you more.
The more you can demonstrate that you are in business-on-own-account, the more confident the client will feel about determining the engagement sits outside IR35.
Remember the rules do not apply where the client is ‘small’, so if you want to avoid these difficult discussions with your clients altogether, and if it’s feasible (which it isn’t for many contractors) find small clients to work with.
If you work via an umbrella company be very, very wary of eye-catching take home rates. It is probably a non-compliant umbrella and you could end up with a huge bill to pay at the end of it.
