What Is IR35?
IR35, also referred to as the "off-payroll working rules," was introduced in 2000 to combat so-called 'disguised employment.' The legislation targets individuals who supply their services to clients via an intermediary, typically a limited company (often termed a personal service company or PSC), but who would otherwise be considered employees if the intermediary did not exist.The objective is not to penalise the self-employed, but to ensure fairness in taxation. As HMRC has stated: "If it looks, works, and acts like an employee, then it is an employee."
Recent Amendments to IR35
- Public Sector: Since 2017, the responsibility for determining IR35 status shifted from the worker to the public sector client.
- Private Sector: This responsibility extended to medium and large private sector clients in April 2021, following a delay from the original 2020 date.
- Full control over business decisions
- Simpler accounting and reporting
- Direct responsibility for all business debts and liabilities
- The rules surrounding employment status (self-employed vs. employed) still apply to sole traders.
- Clients engaging a sole trader must ensure the correct classification; if HMRC deems a sole trader to be an employee, the client may face liability for PAYE and National Insurance contributions.
- The degree of control over how, where, and when work is done
- The ability to send a substitute
- Mutuality of obligation between client and worker
- Filing an annual Self-Assessment tax return
- Paying Income Tax on profits
- Paying Class 2 and Class 4 National Insurance contributions
- Registering and paying VAT if above the threshold
- Operating PAYE for any employees you hire
- Register as a sole trader with HMRC
- Keep accurate records of income and expenses
- File your Self-Assessment return by 31 January each year

Despite these changes, the focus of IR35 remains on engagements involving intermediaries. Sole traders, by definition, are not intermediaries.
