Dive into our guide to gain a deeper understanding of IR35.

IR35 is one of the most important pieces of tax legislation in UK law. The legislation has been active in the United Kingdom since the turn of the 21st century and is constantly evolving as time goes on.

There are many questions and myths around the IR35 legislation, from ‘what is HMRC’s criteria’ to ‘my accountant told me I am IR35 compliant because of X, Y and Z’.

Here at Nixon Williams, we have been advising on IR35 for nearly twenty years. Using this expertise, we have compiled the most asked questions around IR35 and busted a few myths in the process.
