When to Use a Contractor

Engage a contractor when you need specialist expertise for a defined period, the individual genuinely operates their own business, and you do not need to control how the work is performed.

When to Use a Employee

Hire an employee when the role is integral to your business, requires ongoing supervision and control, and the individual will work exclusively or primarily for you.

Which Does Your Business Need?

The distinction depends on the reality of the working relationship, not just the contract wording. Use HMRC's CEST tool as a starting point, but seek professional advice for borderline cases.

FAQ

What happens if HMRC reclassifies a contractor as an employee?

The engaging business may owe backdated PAYE, employer NI, interest, and penalties. For medium and large businesses under off-payroll rules, the fee-payer is liable for the tax.

Does a contractor need their own insurance?

Yes. Contractors typically need professional indemnity insurance and public liability insurance. Employees are covered by the employer's insurance.
