Off-Payroll Working Rules (IR35)

What is IR35?
IR35, or off-payroll working rules, ensures that workers who look like employees and work through intermediaries (like Personal Service Companies, PSCs) pay similar taxes to employees. These rules were introduced in 2000 and were updated for the private sector on 6th April 2021.

What’s Changed?
The responsibility for assessing employment status now lies with the end client, who must determine whether IR35 applies.

What Do Clients Need to Do?
Clients must assess whether IR35 applies before engaging a contractor and provide a written Status Determination Statement (SDS) with the rationale for the decision. This must be shared with all parties in the supply chain, including CBSbutler.
