Independent contractor

An independent contractor is a self-employed person or business that provides services to a company under a commercial contract rather than an employment contract. They invoice for results, decide how the work gets done, carry their own tax and social contributions, and bear their own commercial risk.

The point that matters most in practice: classification is not decided by what the contract is called. Labour inspectorates, tax authorities and courts look at how the relationship actually works, and a contract headed "services agreement" that describes a person sitting in your team, on your schedule, under your supervision, will be read as employment regardless of its title.

Independent contractor vs employee

The tests authorities actually apply

The wording differs by country, but the questions are remarkably consistent:

• Control. Who decides when, where and how the work is done. Fixed hours and a seat in the office point to employment.
• Integration. Is the person part of the organisation or supplying it? Appearing on the org chart, managing employees or holding an internal role are integration signals.
• Substitution. Can they send someone else to do the job? A genuine contractor usually can; an employee cannot.
• Economic dependence. One client providing nearly all of someone's income looks a lot like employment to an inspector.
• Tools and risk. Who provides equipment, who fixes defects at their own expense, who loses money if the project overruns.

No single answer decides it. What decides it is the overall picture, which is why the safest arrangements are the ones that look like contracting on every question rather than on most of them.

Employment status and IR35 in the UK

UK employment law recognises three statuses rather than two. An employee has the full set of rights, including unfair dismissal protection and statutory redundancy pay. A worker has a narrower set: the National Minimum Wage, paid holiday and protection from discrimination. A self-employed contractor has none of these and is protected mainly by the contract. HMRC's Check Employment Status for Tax tool applies the same control, substitution and integration questions for tax purposes.

Contractors who work through their own limited company fall under the off-payroll working rules, known as IR35. Since April 2021, medium and large private sector clients decide whether each engagement is inside or outside IR35 and must give the contractor a Status Determination Statement with the reasons. If the engagement is inside IR35, the fee-payer deducts income tax and National Insurance before paying the contractor's company. Small clients leave that decision to the contractor's own company.

What misclassification costs

Reclassification is rarely a warning letter. It usually means back payment of contributions and taxes for the whole period, plus interest and penalties, and the person acquires employee rights retroactively: paid leave accrued but never taken, notice periods, severance, protection against dismissal. The company also inherits records it never kept, because nobody was tracking working time for someone who was formally a supplier.

The risk is asymmetric in an important way. The arrangement usually suits both sides right up until it does not, and the trigger is almost always a dispute: someone is let go, the relationship sours, and the claim to be an employee all along follows. That is worth remembering when the contractor is the one asking for the arrangement.

When a contractor is genuinely the right choice

Contracting fits a defined deliverable with an end point, specialist work you need occasionally rather than continuously, a genuinely independent professional with several clients, and short-term capacity that does not justify a permanent role. It fits badly where the work is continuous core activity, where the person must follow your process step by step, where you need to direct their daily priorities, and where the role would sit permanently inside a team.

The blunt version of the test: if you would be uncomfortable with the person unilaterally deciding to work Tuesdays only and sending a colleague on Thursdays, you are describing an employee.

What an independent contractor agreement should cover

• Scope and deliverables. What will be delivered, by when, and how acceptance works.
• Fees and invoicing. Rate or fixed price, invoicing schedule, payment terms and expenses.
• Independence. The contractor controls methods and schedule and can use a substitute or subcontractor.
• Intellectual property. Explicit assignment of rights in the work product to the client.
• Confidentiality and data protection. A non-disclosure clause and, where personal data is processed, data protection terms.
• Liability and insurance. Limits of liability and the professional indemnity cover the contractor holds.
• Termination. Notice for ending the engagement and what happens to work in progress.

A well-drafted agreement supports the classification, but it cannot override how the relationship works in practice.

Managing contractors without treating them as staff

• Keep them out of employee processes. Performance reviews, internal goals and mandatory training all read as subordination. Milestones and acceptance of deliverables do not.
• Handle IP explicitly. Rights do not transfer automatically in every jurisdiction. Assignment clauses and confidentiality terms belong in the contract, signed before work starts.
• Track access as carefully as for employees. Contractors often keep system access long after the last invoice, which is where offboarding gaps turn into security incidents.
• Keep the headcount question honest. Contractors are not headcount but they are capacity and cost, so exclude them from one number and include them in the other.

How PeopleForce handles contractors

In PeopleForce, the form of cooperation is its own field, called work type, and the list is configurable rather than fixed, so a company can separate employees, contractors and any other arrangement it uses instead of squeezing everyone into one category. Because that field feeds filters and reports, headcount by work type is a report rather than a manual exclusion, and the employee directory and org chart can be narrowed to employees only when the question is about the organisation rather than about capacity.

Contracts, annexes and acceptance documents are generated from templates and signed through electronic signature, so the paperwork exists in one place instead of in someone's mailbox. Access and offboarding run on workflows anchored to the end date of the engagement, which closes the gap where a finished contractor keeps their accounts. For project work, each person carries a cost rate and a billable rate that can be overridden per project with their own start and end dates, so time logged turns into cost without a separate spreadsheet.

FAQ

What is the difference between an independent contractor and an employee?

An employee works under the employer's control, is paid through payroll and has statutory employment rights. An independent contractor runs their own business, decides how to deliver the work, invoices for it and handles their own tax, with only the rights set out in the contract.

Can an independent contractor work for only one client?

Yes, but it weakens the case for self-employment. Working for a single client full time, on that client's schedule, is one of the strongest signals of employment, so the other factors such as control, substitution and own equipment carry more weight.

Who decides IR35 status in the UK?

For medium and large private sector clients, the client decides and issues a Status Determination Statement. For small clients, the contractor's own limited company decides. In the public sector, the public body decides.

Do independent contractors get holiday pay?

Genuinely self-employed contractors do not. If the relationship is reclassified as worker or employee status, the person can claim holiday pay for the period they should have had it.
