What is IR35?
IR35 is an anti-tax avoidance regime which is intended to tackle (in HMRC’s view) the long standing issue of individual contractors providing their services or labour via an intermediary – which is usually a personal service company (referred to as a PSC). We’ll talk about PSCs here, but there are other types of intermediaries that are caught.
HMRC’s view is that this arrangement is often considered to be disguised employment and therefore a tax-avoidance arrangement.
So IR35 is essentially a test of employment status – and if, once you apply the test, the contractor should be an employee, they should then be taxed as an employee.
