Outside IR35 in 2026: Is It Still Achievable and Worth Fighting For?
When IR35 reform landed in the private sector in 2021, many observers predicted the death of outside IR35 contracting. That proved too pessimistic. In 2026, outside IR35 work hasn't disappeared - but it has changed shape significantly, and the JSL reforms may be creating new openings.
The Current State of Outside IR35
In 2026, the market has broadly stabilised after the upheaval of the 2021 reforms. Many larger clients did shift to blanket inside IR35 determinations in the immediate aftermath, but a significant proportion have since revisited their approach - particularly those that lost key specialist contractors as a result. Outside IR35 work is most readily available in three scenarios: genuine project-based SoW engagements; smaller private sector clients below the IR35 medium/large employer threshold; and niche specialist roles where clients have accepted they must offer outside IR35 status to secure the talent they need.
The JSL Effect
The introduction of Joint and Several Liability rules from April 2026 has had an interesting secondary effect on the IR35 landscape. Some clients and agencies, now acutely aware of the financial risk carried in umbrella supply chains, are actively exploring SoW and project-based delivery models as a way to reduce that exposure. First Point Group's analysis suggests that JSL reviews at client organisations could result in increased adoption of SoW models - which, when structured correctly, naturally support outside IR35 status.
How to Qualify for Outside IR35
HMRC's assessment of IR35 status turns on three key pillars: substitution (can you send a substitute to do the work?), control (does the client control how, not just what, you deliver?) and mutuality of obligation (is there an expectation of ongoing work and pay beyond the defined project?). To support an outside IR35 status, your contract and actual working practices must genuinely reflect business-to-business independence. This means having a clear scope of work, avoiding fixed working hours, not being integrated into the client's permanent team structures, and ideally retaining the right of substitution.
Getting a Status Determination Statement
Since 2021, medium and large private sector clients are responsible for issuing a Status Determination Statement (SDS) assessing your IR35 status. If you're working on a role that you believe should be outside IR35, it is worth requesting a detailed SDS and, if you disagree with the determination, following the client's appeals process with supporting evidence. Services like Qdos and ATUM provide contract reviews and insurance-backed IR35 status opinions that can support your position.
Is It Worth the Effort?
On a £600 per day rate, the difference between inside and outside IR35 is roughly £15,000–£20,000 per year in take-home pay. For that differential, the additional effort of structuring your engagement correctly, maintaining appropriate working practices and ensuring your contract reflects genuine business-to-business independence is almost certainly worth it. The key is ensuring your actual day-to-day working relationship matches the contractual position - HMRC is increasingly focused on the reality of how contractors work, not just the paperwork.
