NRP Compliance Series – Protecting Construction and Civil Engineering Firms from Hidden Payroll and Employment Risks
Post 1: Misclassification Risk – When “Self-Employed” Isn’t What HMRC Thinks
Many construction and civil engineering firms use self-employed sole traders for project work. It feels simple, flexible, and familiar, but it can quickly become a problem if those workers are not genuinely self-employed in HMRC’s eyes.
What the issue is
HMRC focuses on how people actually work, not just what the contract says. If a sole trader is working under supervision, direction, and control, HMRC may decide they are really an employee.
When that happens, the company becomes responsible for unpaid PAYE, National Insurance, and penalties because those individuals should have been on PAYE rather than paid as self-employed.
What this looks like in real life
If your site team wears your PPE, follows your site manager’s instructions, uses your equipment, and works set hours, HMRC could class them as employees. That can mean several years of backdated tax, NI, and fines.
The financial impact
Even a small reclassification can snowball. Once one worker’s status is questioned, HMRC often reviews your entire labour setup. The result can be a large tax bill and a serious compliance headache.
How to protect your business
By engaging self-employed workers through NRP’s CIS model, you gain the flexibility of self-employment with the safety of full HMRC compliance.
Workers remain self-employed, but NRP verifies, insures, and manages them under CIS rules, taking care of deductions, submissions, and records.
It keeps your structure flexible, your workforce compliant and your company protected.
