This tool provides guidance only and is not a substitute for professional tax or legal advice. IR35 determinations depend on the specific facts of each case and contract terms.

HMRC's CEST tool is the official Check Employment Status for Tax service. This assessment should be used alongside CEST and professional advice.

Contract terms matter: The actual contract terms and working practices both influence IR35 status. Ensure your contracts reflect your intended working relationship.

Seek professional advice: For complex situations or high-value contracts, consult with a qualified tax advisor or specialist IR35 consultant.

🔗 Official HMRC Resources:

Use HMRC's Check Employment Status for Tax (CEST) tool for the official determination. This assessment tool should complement, not replace, the official CEST evaluation.
