IR35 determination tool for End Clients – now available


NASA have been developing a policy & process for End Clients to follow, utilising our more than 13 years’ experience of assessing our clients for IR35. This process includes a simple ‘IR35 Determination Tool’.


This process & tool will:

  • Support end clients to develop and implement a policy & process to assess contractors for IR35

  • Ensure 'reasonable care' & provide correct IR35 status determinations for contractors

  • Provide an independent IR35 assessment, overcoming the known flaws & bias of CEST

  • Human checking of borderline submissions by NASAs IR35 experts

  • Generate a status determination statement (SDS) for each assignment, which can be passed down the supply chain

  • Simple & scalable process which can be 'owned' by end client representatives, with little training and ongoing support required

  • Help maintain a flexible contractor workforce with the most highly skilled PSC contractors


For more information how NASA and our IR35 services can help you and your clients prepare for the IR35 reform click here to submit your details to our team. We’ll be happy to have a chat or provide a demo of the tool for you.
