And trust us, after 20+ years watching this game, our cynicism alarm is screaming.
-
A long-serving employee or contractor (or maybe a recruiter who worked closely with a client) leaves a major SaaS scale-up (let’s call them “Client X”).
-
They immediately set up a shiny new Limited Company, call it “Innovate Strategy Services,” and start supplying contractors only to Client X.
-
The contract? It’s a “mates agreement.” A handshake, a wink, and a verbal promise that they’re a “consultancy” providing a managed service—not just a poorly equipped inexperienced recruitment firm.
If you have one client, no other sales pipeline, no proprietary IP, no financial risk (your entire business folds if Client X walks away), and you’re just billing for the day-rate of the people you place… you are a recruitment agency. End of.
Under the new Off-Payroll rules, the End Client (Client X) is responsible for determining the IR35 status of the worker.
-
The Intermediary is the Fee Payer: That brand-new, single-client “Innovate Strategy Services” (the Faux-sultancy) becomes the Fee Payer.
-
The Liability: When HMRC proves that the contractors supplied are Inside IR35 (because they’re acting like employees of Client X), the tax liability for all unpaid Income Tax and National Insurance falls squarely on that Faux-sultancy.
-
Insolvency: A single-client company with no balance sheet can’t pay a retrospective multi-million-pound tax bill. It goes bust.
-
The Boom goes back to Client X: When the Fee Payer goes bust, HMRC can and will chase the End Client (Client X) for the liability, arguing they failed in their duty of reasonable care by allowing this sham structure to exist in the first place.
Our founder said it in one of his blog posts: Don’t let the fakes in life rent space in your mind. That applies to your vendors, too.
If a “Consultancy” is knocking on your door, and their only business is based on a mate’s agreement, a flimsy contract, with inflated prices for the same service under another name… step back. Question everything.
If you’re the line manager signing off on that, realise your CEO is likely to be displeased you chose to help your mate out with his new gig. Getting lousy value and an HMRC tax bill for your trouble.
-
If you’re a recruiter, be a great recruiter.
-
If you’re a genuine consultancy, prove it with multiple clients, clear SOWs, and financial risk.
