IR35 Explained: A Guide for Self-Employed and Contractors
As a self-employed individual or contractor in the UK, you have likely encountered the term IR35. But with shifting rules and complex tax implications, understanding exactly how it affects your business can be challenging.
What is IR35? How do you know if you are "inside" or "outside"? And importantly, who is responsible for making that decision?
This guide breaks down the off-payroll working rules to help you navigate compliance with confidence.
What is IR35?
IR35, officially known as the off-payroll working rules, is a piece of UK tax legislation introduced by HMRC in 2000. Its primary purpose is to combat "disguised employment."
Disguised employment occurs when a worker provides services to a client through an intermediary (usually a limited company or Personal Service Company) but, for all intents and purposes, acts as an employee.
If you are found to be a "disguised employee," HMRC requires you to pay roughly the same Income Tax and National Insurance contributions as a regular employee, rather than enjoying the tax efficiency of a business structure.
Inside IR35 vs. Outside IR35: What’s the Difference?
Understanding your status is vital because it dictates how you get paid and how much tax you owe.
What does Inside IR35 mean?
If a contract is classified as Inside IR35, it means HMRC considers you an employee for tax purposes, even if you're working through your own limited company.
So, what does this mean for you?
- How are you taxed? You are required to pay Income Tax and National Insurance Contributions (NICs) at the same rate as a permanent employee. Your client or the agency paying you will typically deduct these taxes at source through PAYE (Pay As You Earn) before you receive your payment.
- What's the financial impact? Because you're taxed like an employee, your net take-home pay is generally lower than if you were operating outside IR35.
- Do you get employee rights? This is a key point: despite being taxed as an employee, being inside IR35 does not automatically give you employment rights like statutory sick pay or holiday pay. Your rights depend entirely on the terms of your specific contract.
What does Outside IR35 mean?
If your contract is determined to be Outside IR35, HMRC considers you a genuine independent business providing services to your client. This means you are responsible for managing your own business taxes.
- What are the tax implications? You’ll handle your own tax and National Insurance contributions through your limited company. This often involves paying yourself a combination of a salary and dividends, which can be a more tax-efficient structure.
- What is the financial impact? Your take-home pay is typically higher than it would be for an inside IR35 contract because you can structure your payments more efficiently.
- Who holds the responsibility? You maintain full autonomy over your business operations and how you deliver your services to the client.
Determining Your Status: The 3 Key Tests
How HMRC Determines Inside or Outside IR35 Status
HMRC assesses your IR35 status based on your actual working practices, not just your contract. Here are the three key factors they evaluate:
- Control: Who decides how, when, and where the work is done? If the client has significant control, you’re likely Inside IR35. If you have autonomy over how the work is completed, you’re likely Outside IR35.
- Substitution: Can you send a substitute to complete the work? A genuine right of substitution indicates you’re operating as a business (Outside IR35). If you’re required to personally do the work, you may fall Inside IR35.
- Mutuality of Obligation (MOO): Is there a mutual expectation of ongoing work? If the client is obligated to provide work and you’re obligated to accept it, this suggests an employee-like relationship, pointing to Inside IR35.
Understanding these factors can help you determine your IR35 status and ensure compliance.
Who Decides Your IR35 Status? (IR 35 New Rules)
The rules for determining your IR35 status changed in April 2021. Here's what you need to know:
- Medium and Large Clients: The client is responsible for deciding your IR35 status. They must provide a Status Determination Statement (SDS) outlining their decision.
- Small Business Clients: If your client qualifies as a "small business" under the Companies Act 2006, you (the contractor) are responsible for determining your IR35 status.
Understanding these guidelines is essential to ensure compliance and avoid complications.
How to Check Your Status: The CEST Tool
HMRC offers a free tool called Check Employment Status for Tax (CEST) to help businesses and contractors determine if a worker is employed or self-employed for tax purposes. By answering questions about key factors like substitution, control, and working relationships, the CEST tool provides a clear employment status determination. While useful, the tool has been criticized for being overly cautious in some cases. For complex situations, consulting a specialized accountant is recommended to ensure accuracy.
Summary Checklist
- Check your client size: Do they determine your status, or do you?
- Review your contracts: Do they reflect a business-to-business relationship?
- Assess working practices: Do you have control? Can you send a substitute?
- Use the CEST tool: Get an initial view from HMRC’s official tool.
- Get expert advice: If in doubt, consult a tax professional to ensure you are compliant.
IR35 Insurance: Protecting Your Business
Navigating IR35 legislation can be complex, and even with the best preparations, there is a chance of disputes or investigations by HMRC. This is where IR35 insurance becomes essential for small business owners, contractors, and freelancers. IR35 insurance provides financial protection if HMRC challenges your employment status or if you face tax liabilities due to an IR35 determination.
Key Benefits of IR35 Insurance
- Coverage for HMRC Investigations: Ensures support for the costs associated with responding to IR35-related HMRC inquiries or disputes.
- Tax Liability Protection: Covers additional tax, interest, and penalties if your contract is deemed to fall inside IR35.
- Legal Defence Costs: Supports legal representation and advice during IR35 disputes, securing your rights and minimising stress.
- Peace of Mind: Helps you focus on running your business without constantly worrying about potential HMRC challenges.
IR35 insurance is particularly important if you're unsure about your IR35 status or if your contracts are especially complex. Policies vary by provider, so it’s essential to choose one that aligns with your specific business needs.
Should You Consider IR35 Insurance?
If you regularly work as a contractor or freelancer under limited company arrangements, or if your business faces regular contractor engagements, IR35 insurance can safeguard your financial health. While preparing for compliance with tools like HMRC's CEST tool is crucial, having IR35 insurance adds an extra layer of security against unforeseen tax challenges.

Comprehensive IR35 insurance can be the safety net your business needs in an unpredictable regulatory environment. Pairing this with proactive management of your contracts, employment practices, and compliance measures will ensure your peace of mind, no matter what comes your way.
