Most agencies treating IR35 compliance for recruiters as a paperwork exercise are one investigation away from a costly wake-up call.
The off-payroll working rules place real obligations on recruitment agencies. Status determination statements matter. But they’re the starting point, not the finish line. When HMRC opens an inquiry into a contractor arrangement, it looks beyond the SDS. It examines what you knew, what you recorded, and whether your supply chain was genuinely operating within the rules.
That’s a fundamentally different question.
What IR35 Compliance Actually Requires from Recruiters
If you’re placing workers through umbrella companies, your IR35 obligations don’t stop at the SDS. You need to know that every umbrella you use is deducting the right amounts, paying workers correctly, and maintaining compliant payroll records.
An SDS tells HMRC what status you determined. Your supply chain records tell HMRC what you actually monitored. Without the second, the first won’t protect you.
The Gap Most Agencies Don’t Notice
The gap isn’t usually deliberate. Most agencies maintain an approved supplier list. Some have FCSA accreditation records on file. What they rarely have is a continuous, auditable log of compliance across every umbrella they use.
HMRC doesn’t audit your records when everything runs smoothly. It audits them when something has already gone wrong. At that point, any gap in your evidence trail becomes exactly what investigators look for.
Payslip-level compliance data captured in real time is far more credible than records assembled after the fact.
