CIS Subcontractor vs Employee: How to Know Where You Stand with HMRC

If you work in the UK construction sector, you are likely very familiar with the Construction Industry Scheme (CIS). It is a system designed to handle tax deductions smoothly, but things can quickly get complicated if your true working status is unclear. Whilst we regularly help property investors with general compliance and things like let property campaign assistance in London, we also spend a massive amount of time helping site workers figure out exactly where they stand with their employment classification.

HMRC is currently cracking down on what they call false self-employment. This happens when a building firm treats a worker like a standard employee but pays them as an independent subcontractor to save on National Insurance contributions.

Getting this wrong can lead to serious financial penalties for contractors and major confusion when it is time to submit your annual tax paperwork. Let us break down the main differences in simple, plain English.

The Reality Test: Subcontractor or Employee?

HMRC does not just look at what is written in your contract; they look at the daily reality of your working relationship on site. To figure out your true status, ask yourself three essential questions:

Can you send a substitute? If you cannot make it to a site, do you have the right to hire another qualified trade professional to do the work in your place? If the answer is yes, you are a subcontractor. If the boss insists that only you can do the job, you look like an employee.
Who controls your day? A genuine subcontractor is hired to complete a specific task, like fitting a kitchen or wiring a floor, and decides how to do it. If a site manager supervises your every move, tells you exactly what tools to use, and dictates your precise working hours, HMRC will likely view you as an employee.
Who carries the financial risk? Do you provide your own heavy-duty tools, buy your own materials, and fix your own mistakes on your own time? Subcontractors carry real commercial risk. Employees, on the other hand, are provided with tools, get paid an hourly rate regardless of hitches, and bear no financial loss if a job goes over budget.

Why Your Classification Matters

Should you be truly self-employed on a CIS basis, then the contractor will deduct 20% (or 30% if not verified) from your payment and send it to HMRC. It would be necessary for you to reclaim any excess tax that might have been deducted through a CIS Tax Return in the UK at the end of the year. But if HMRC finds out that you are actually an employee, then you should be on a regular PAYE payroll scheme, receiving holiday pay, sick pay, and workplace pension contributions.
