IR35 Status Checker
Answer 10 questions about your working arrangement to get an indicative IR35 assessment. This is not legal advice — always consult a specialist for a formal determination.
How to Read an IR35 Result
This checker is only a structured prompt. IR35 status depends on the contract and the real working practices, so a borderline or high-value engagement needs proper review.
Good for
- Spotting common employment-status risk factors
- Preparing questions before a contract review
- Comparing how substitution, control, integration, and financial risk affect status
Watch for
- A written contract may not reflect how the work actually happens
- Each engagement needs its own assessment
- Client size can affect who is responsible for determining status
Speak to a specialist when
- The contract is high value or long running
- The result is borderline or the client disagrees with your view
- You need a formal status determination or contract review evidence
IR35 guidance reviewed on 2 June 2026. This tool is indicative only and should be checked against official off-payroll working guidance.
Can you send a substitute to do the work in your place?
A genuine right of substitution (without client approval) is a strong indicator of self-employment.
Does the client control what work you do?
If the client dictates specific tasks rather than just deliverables/outcomes, this points toward employment.
Does the client control how you do the work?
If the client dictates your methods, tools, or processes, this suggests employment.
Does the client control when and where you work?
Fixed hours and mandatory office attendance suggest employment.
Do you provide your own equipment and tools?
Providing your own significant equipment (laptop, software licenses) suggests self-employment.
Do you bear financial risk (e.g., fixing mistakes at your own cost)?
Bearing financial risk for defective work is a hallmark of genuine self-employment.
Are you prevented from working for other clients?
Exclusivity clauses suggest employment. Being free to work for others suggests self-employment.
Are you treated as part of the client's staff (company email, org chart)?
Being integrated into the organisation's structure suggests employment.
Do you receive employee benefits (holiday pay, pension, sick pay)?
Receiving employment benefits is a strong indicator of employment status.
Are you engaged for a specific project or deliverable?
Working on defined projects with clear end dates suggests self-employment.
Important Disclaimer
This tool provides an indicative assessment only and does not constitute legal or tax advice. IR35 status is determined by the specific facts of each engagement. Since April 2021, medium/large private sector clients are responsible for determining IR35 status. Always seek professional advice for a binding determination.
