An overview of the Intermediaries Legislation (IR35), specifically how it affects limited company contractors. How to determine your risk of being caught by IR35, and how to protect yourself against a potential HMRC tax investigation.
IR35 Rules
The Intermediaries Legislation was introduced in 2000 to tackle 'disguised employment', where an individual uses a limited company to carry out professional services, but works in a manner more like an 'employee'. Your take home pay will be significantly lower if your contracts fall within its scope.
Off-Payroll Rules
The 'off-payroll' addition to the existing IR35 rules was introduced across the public sector in April 2017 and the private sector in April 2021.
The 'Off Payroll' rules mean that clients (not contractors) are responsible for determining the employment status of contractors. Before this, workers themselves were responsible for this determination.
