Navigating IR35
IR35, officially known as “Off-payroll”, is legislation that targets tax avoidance by contractors. Essentially, it is a set of rules determining whether a contractor is genuinely self-employed, or instead an employee “disguised” as a contractor for tax purposes.

What do you need to know?
IR35 determinations are to be done and completed by the business hiring the Contractor
The IR35 status of the Contractor dictates whether they are treated as an employee or contractor for tax purposes. Let’s compare inside versus outside IR35:
Inside IR35 meaning
The worker is classed as an employee for tax purposes. They’ll pay the same Income Tax and NICs as if they were an employee.
Outside IR35 meaning
The engagement has been deemed a genuine business to business relationship or contractor genuinely self-employed. As a result, they can fully reap the rewards of self-employment and remain responsible for paying their own taxes like Income Tax and National Insurance Contributions.
