Dave Chaplin, CEO of IR35 compliance firm IR35 Shield and author of IR35 & Off-Payroll Explained on why contractors win in 2026.
UK businesses are under mounting pressure. Taxes are rising, growth is stagnant, and the cost and risk of hiring employees continues to climb. At the same time, firms are being asked to move faster, deliver more, and remain competitive in an economy that offers little margin for error.
Against this backdrop, a quiet but powerful shift is underway. A combination of legislative change, economic pressure, and technological disruption is reshaping how work gets done. The unintended consequence is inevitable: the most profitable firms will be moving away from traditional employment and towards contractors.
What once looked like a compliance risk has become a commercial opportunity.
A Perfect Storm for Traditional Hiring
Several forces are converging to make on-payroll hiring slower, riskier, and more expensive:
- The Employment Rights Act 2025 is rolling out new obligations through 2026 and beyond
- Conduct of Employment Regulations are being expanded
- New Umbrella Tax Avoidance Rules arrive in April 2026
- Firms face higher taxes and prolonged economic stagnation
- Generative AI is reducing the need for large permanent workforces
Individually, each adds friction. Collectively, they fundamentally weaken the business case for permanent hiring – while strengthening the case for contractors.
IR35: From Commercial Blocker to Manageable Risk
When the off-payroll rules arrived in 2017, many firms reacted defensively. The legislation contained a serious flaw: if a contractor was misclassified, the hiring firm could be liable for up to 50 per cent of the total fees paid. Case law was unsettled, HMRC enforcement was unpredictable, and blanket bans became a rational, if somewhat blunt, response.
That risk profile no longer exists.
In April 2024, the offsets legislation corrected the flaw. Firms no longer pay someone else’s tax twice. In practical terms, the residual risk now sits below 10 per cent of contractor fees and even that assumes an unusually high error rate. For a well-run business, the real exposure is often closer to 1 per cent of total contingent spend.
In September 2024, the Supreme Court settled a decade of legal uncertainty by ratifying the long-established case law principles in Atholl House Productions. Firms now know what they can rely on.
HMRC’s enforcement approach has also matured. Compliance checks focus on the quality of status determination processes, not technical perfection. Where risk is demonstrably low, investigations stop early. For prepared firms, checks typically conclude within months.
The result is simple: IR35 is no longer a commercial reason to avoid contractors. Firms that still behave as though they are making decisions based on outdated assumptions are paying for them in higher costs and slower delivery.
Costly Employment and Tax Law Is Expanding
While IR35 risk has receded, the cost and complexity of employing workers continues to rise.
The Employment Rights Act 2025 introduces phased changes that increase obligations across the supply chain. Umbrella companies are now being pulled into the definition of employment businesses and brought under updated Conduct Regulations. At the same time, new tax avoidance legislation in April 2026 introduces joint and several liability when umbrella workers are paid.
In effect, tax and compliance risk is being pushed upstream towards agencies and, in some cases, end clients. While workable, the model is undeniably more complex. bringing exposure and process drag.
By contrast, genuine off-payroll contractors sit largely outside this expanding framework. No employment rights burden. No umbrella liability chain. No payroll-centric risk model.
As employment law thickens, contracting becomes the cleaner, simpler option.
Economic Stagnation, AI, and the Shift to Outcomes
Economic growth remains elusive. Firms are under pressure to do more with less, and generative AI is accelerating that reality. Tools such as ChatGPT, Gemini, and Claude are dramatically increasing individual productivity, reducing the need for large teams and long hiring cycles.
But AI does more than cut costs. It changes how value is delivered.
Service buyers are increasingly focused on outcomes, not hours. AI-enabled sellers can undercut traditional providers by delivering more cost effectively. That model aligns naturally with contracting.
Deliverables-based work is a contract for services. IR35 does not apply. Employment legislation does not apply. The administrative burden is removed. Hiring contractors to deliver outcomes is not only faster, but also structurally more profitable than employing workers to provide time and skills.
AI accelerates this shift. It rewards lean, agile operating models built around a small core workforce, supplemented by specialist contractors who deliver defined results.
Contractors as the Growth Engine
The law of unintended consequences from legislative change is playing out once again.
Legislation designed to regulate work and protect workers is inadvertently pushing firms away from permanent employment. Economic stagnation is amplifying cost sensitivity. AI is reshaping delivery models. Together, these forces are driving a behavioural shift that is both rational and inevitable.
Firms that want growth, speed, and profitability are increasingly choosing to hire contractors off-payroll to deliver outcomes. Those that cling to traditional employment models face higher fixed costs, slower execution, and greater risk.
In 2026, the path to profits is about flexibility, and outcome-driven.
And it is paved with contractors who provide services.
