Understanding IR35
IR35 is UK tax legislation that determines whether a contractor is genuinely self-employed or a disguised employee. Your IR35 status significantly affects your take-home pay. For authoritative guidance, refer to GOV.UK's IR35 guidance. You may also find our Freelance True Day Rate Calculator helpful for understanding your real earnings.
Getting Your Status Right
HMRC provides the Check Employment Status for Tax (CEST) tool to help determine IR35 status. Key factors include control over how work is done, the right to send a substitute, and mutuality of obligation. Getting professional advice is recommended for borderline cases.
