How IR35 impacts the way you hire contractors
Hiring contractors has always given businesses agility. You can bring in specialist skills quickly, scale up a project team at pace or cover gaps without committing to permanent headcount. But IR35 has changed contractor recruitment in the UK, and it changes how organisations have to approach hiring. At Vermelo, we help businesses cut through the complexity with a structured way to manage contractor hiring through our managed service provider (MSP) solution.
Understanding IR35
IR35 is legislation designed to ensure that individuals who work like employees but bill through their own limited company or personal service company (PSC) pay broadly the same tax and National Insurance as employees. Responsibility for assessing whether a contractor falls inside or outside IR35 used to sit with the contractor. That changed in the public sector in 2017 and, from April 2021, for medium and large organisations in the private sector. Small companies are exempt, and there the contractor's own company remains responsible.
If your organisation is in scope and you engage contractors, you are accountable for determining their status, issuing a status determination statement, and ensuring the right tax treatment follows. Get it wrong and the business can be liable for backdated tax, interest and penalties. Natural Resources Wales' £14.6 million settlement in 2025 is the recent example everyone cites.
The risks of getting IR35 wrong
IR35 has created uncertainty for many organisations. Some worry about attracting HMRC scrutiny. Others are concerned about losing contractor talent who prefer outside-IR35 roles. The risks are real: financial penalties if HMRC finds misclassification, extra administrative burden on hiring managers, loss of contractor goodwill if assessments are unclear or delayed, and project disruption if roles are wrongly scoped or the compliance isn't watertight. For businesses that rely on flexible talent, any of these can stall projects and make it harder to stay competitive.
Why businesses need a more structured approach
Traditional in-house contractor hiring struggles to keep up with the compliance requirements of IR35. Individual hiring managers are rarely compliance experts, yet they are asked to make complex determinations about tax status. Without standardised processes, documentation and clear communication, mistakes creep in one engagement at a time.
That's where a structured MSP model makes the difference. It doesn't remove your responsibility for status determinations; it gives you a consistent, documented process that makes those determinations defensible. If you're weighing up providers, our guide to choosing a recruitment MSP covers master versus neutral vendor and how to tell who means it on compliance.
How Vermelo's MSP solution helps
We design our MSP approach to give you control, visibility and consistency from the outset. Instead of leaving contractor hiring as an ad hoc process, we bring structure and expertise.
Standardised processes: every contractor engagement is managed within one framework. From initial role definition through to onboarding, IR35 checks are part of the process, not an afterthought.
Pre-employment checks: every contractor is vetted properly, so you have confidence in both compliance and capability.
Clear accountability: our specialists support and document status determinations and reporting, so the reasoning behind each decision is recorded and retrievable. That protects the business and reassures contractors.
Access to talent: with a contractor recruitment network across industries and geographies, you can fill roles quickly and reach scarce skill sets without compliance concerns holding you back.
Actionable insight: management information gives you visibility of contractor spend, usage and compliance status, so you can make strategic workforce decisions rather than tactical hires.
In short, we make contractor hiring faster, easier and safer, so you can focus on delivery rather than paperwork.
The wider benefits of an MSP model
IR35 compliance may be the trigger for change, but the benefits of an MSP go beyond avoiding risk. Businesses that move from fragmented contractor hiring to an MSP model typically see faster time to hire through streamlined processes, better candidate quality from proactive sourcing, reduced cost from consolidated supply chains and clearer workforce planning, an improved contractor experience through transparent communication on assessments, and strategic workforce planning supported by proper management information. In a regulated business, it's also one of the five bottlenecks that surface when you scale, and the one that stays hidden longest.
Why choose Vermelo
We understand the pressures hiring managers face. The need to deliver projects at speed collides with the complexity of compliance. Our MSP approach gives you rapid access to the contractors you need, backed by a structured, documented process behind every engagement.
Whether you're filling a gap, sourcing niche skills or building a project team, Vermelo brings structure to fragmented contractor hiring and turns it into a strategic advantage.
Nothing here is legal or tax advice. IR35 and off-payroll obligations depend on your circumstances and should be confirmed with a qualified adviser.

IR35 and hiring contractors, answered
Since April 2021 in the private sector (and 2017 in the public sector), the organisation engaging the contractor is responsible for determining status and issuing a status determination statement, provided it counts as medium or large. Small companies are exempt, and there the contractor's own company remains responsible. This is general commentary rather than advice; the detail depends on your circumstances and should be confirmed with a qualified adviser.
The off-payroll rules that moved responsibility to the client apply to medium and large organisations. If your business meets the small company definition, the responsibility for assessing status stays with the contractor's own limited company, as it did before 2021. The thresholds and the definition can change, so check your position with an adviser rather than assuming.
By making contractor engagement one consistent process. Every role is assessed against the same framework, the reasoning is documented, the checks happen in the same order, and there's a single record of who is engaged, how and on what terms. Hiring managers stop being asked to make tax-status judgements on their own, and the business has an audit trail rather than a set of email chains. It doesn't remove the client's legal responsibility; it makes that responsibility defensible.
