It isn't the rules. It's the reality on the ground.
Tax risk
You're asked to prove 'reasonable care' with messy forms and shaky evidence. One borderline case can become an expensive problem. Your personal reputation is on the line alongside your business.
Access to talent
Blanket 'PAYE-only' workarounds stall programmes, and significantly increase cost. Line managers game question sets to force an 'outside' result - or bypass the process altogether.
Will a compliance partner understand us?
You've tried tools and templates. They don't know your business, your projects, your managers - or what actually happens day-to-day.
In-house strain
Qualified in-house employment status experts are rare, doing everything yourself means delays, inconsistency and no scale.
If this sounds familiar, you're not alone.
CoComply: Simple, Embedded, Defensible
IR35 and Worker Classification you can rely on - without blocking the business.
Video-first assessments for every role
Replace static forms with a short live review led by an employment status specialist. This captures the real working practices that shape IR35 outcomes. We know what to ask - and what HMRC looks for - so your assessments pass scrutiny.
We learn how your business really works
Your dedicated Employment Status Account Manager meets with your teams (in person where helpful), builds a deep understanding of how you deliver work and hire talent, and joins regular reviews to stay aligned. Determinations reflect your actual operations - not generic templates. And if we're not confident in a classification, we'll tell you.
Powered by award-winning AI
Our next-generation platform gives you seamless processes, reporting, and visibility. You'll know where you stand, adjust policy as needed, and see where risks lie.
Blending cutting-edge technology with human expertise
AI-powered platform augmented by employment status specialists
Rapid onboarding
Drop Contractor list, MSAs, SoWs and change agreements into CoComply to onboard your suppliers, contractors and agencies in seconds.
See who's doing what and for how long
Identify hidden headcount and ensure long-standing 'consultants' are properly classified and compliant.
Policy by role
Define clear guardrails for common roles ('this role is normally inside/outside because…'). Managers follow simple guidance; exceptions are escalated for review. The result: consistent decisions with less internal debate.
Project agreements, reviewed in plain English
Before you sign, we review Statements of Work to ensure they reflect true project delivery—not disguised staff augmentation. We clarify deliverables, milestones, and acceptance criteria. Where needed, we take ownership of the classification process. All activity is tracked in a single dashboard.
A single, defensible evidence pack
Every determination includes an SDS, working practices summary, rationale, and any disagreement trail—ready for HMRC or Internal Audit if required.
The result?
You reduce risk, gain control, and keep compliant access to top talent open.
