## Key takeaways

- Employees have employment rights and are taxed through PAYE; contractors run their own business and handle their own tax.
- Status is determined by the working reality, not by what a contract or invoice calls the relationship.
- Contractors suit specialist, project or flexible needs; employees suit ongoing, core, integrated roles.
- Misclassifying staff can lead to back taxes, penalties and tribunal claims, so assess each role honestly.
- This is general information, not legal or tax advice — check GOV.UK and take professional guidance.

When a business needs work done, one of the first practical questions is whether to employ someone or engage a contractor. The choice affects cost, flexibility, control, legal obligations and tax — and getting it wrong is not just an administrative slip but a genuine financial and legal risk. Crucially, you do not get to decide status simply by what you call the relationship: the law looks at how the work is actually carried out. This guide sets out the real differences between contractors and employees, the rights and tax that follow, and when each makes sense. *This is general information, not legal or tax advice.*

## What the difference really is

**An employee works for you under a contract of employment with a defined set of legal rights, while a contractor is in business on their own account and provides services to you as one of their clients.** That single distinction drives almost everything else — rights, tax, cost and control.

The most important principle to grasp early is this: **status is determined by the reality of the working relationship, not by the paperwork.** Issuing invoices, calling someone "self-employed", or writing "contractor" on an agreement does not make it so. If someone works like an employee — under your direction, doing the work personally, integrated into your team — the law may treat them as one regardless of the label. This is the same reality test that underpins the [off-payroll working rules (IR35)](/business/what-is-ir35).

> You cannot label your way out of employment. HMRC and employment tribunals look through the contract to how the work is genuinely done.

## Rights: what each is entitled to

This is one of the starkest differences. **Employees** have a wide range of statutory rights, which typically include:

- Paid holiday and statutory sick pay
- Protection from unfair dismissal (after a qualifying period)
- Statutory redundancy pay (after a qualifying period)
- Maternity, paternity and other family-related leave and pay
- Automatic enrolment into a workplace pension
- The right to a written statement of employment particulars

**Genuine contractors** receive none of these from the client. They are running their own business and carry their own risk, arrange their own time off, and make their own pension provision.

Importantly, UK law recognises a **third category — "workers"** — who sit between the two. Workers are not full employees but do enjoy some core rights, such as paid holiday and the minimum wage. Casual, agency and some gig arrangements can fall here, which is why status questions are not always a simple either/or.

## Tax: how each is handled

The tax treatment follows the status:

| | Employee | Contractor (self-employed) |
|---|---|---|
| Income tax | Deducted at source via PAYE | Self-assessed and paid by the contractor |
| National Insurance | Employee and employer NICs | Contractor's own (different classes) |
| Who handles it | The employer | The contractor |
| Benefits in kind | Reported by employer | Generally not applicable |

For **employees**, you operate **PAYE**, deducting income tax and National Insurance before they are paid, and you pay employer's National Insurance on top. For **contractors**, you generally pay their invoices gross, and they are responsible for their own tax through Self Assessment or their own limited company. Understanding the building blocks here helps — see our explainers on [National Insurance](/business-finance/what-is-national-insurance) and [the self-assessment tax return](/business-finance/self-assessment-tax-return-guide).

## Cost and control: the practical trade-offs

Beyond rights and tax, the two models behave very differently in practice.

**Contractors** typically offer:

- **Flexibility** — engage them for a project or a period, then stop without redundancy obligations.
- **Specialist skills on demand** — bring in expertise you need only occasionally.
- **Lower ongoing commitment** — no holiday pay, sick pay or pension contributions from you.

But the headline day rate is usually higher than an equivalent salary, you have **less control** over how and when they work, and they may juggle other clients. Direct too much, integrate them too deeply, and you risk turning the relationship into employment in the eyes of the law.

**Employees** offer:

- **Control and continuity** — you direct their work and build long-term capability.
- **Commitment and integration** — they become part of the team and culture.
- **Investment in skills** — training an employee benefits you over time.

The cost, though, is greater: salary plus employer's National Insurance, pension contributions, holiday and sick pay, and the responsibilities and protections that come with employment. Building a team also means thinking carefully about roles and reward — our guides on [how to write a job description](/business/how-to-write-a-job-description) and managing people are useful starting points.

## When to use each

There is no universal right answer, but some clear signals help:

**Lean towards a contractor when:**

- The work is a defined, time-limited project.
- You need a specialist skill only occasionally.
- Workload fluctuates and you need to flex up and down.
- The role does not require deep integration into your team.

**Lean towards an employee when:**

- The role is ongoing and central to the business.
- You need close control over how and when the work is done.
- Continuity, commitment and culture matter.
- You want to develop the person's skills over time.

A sensible way to frame the decision is to think about the role, not just the cost — weighing the long-term value of continuity against the flexibility of engaging help only when you need it.

## The risk of getting it wrong

Misclassifying an employee as a contractor is a serious matter. If HMRC or a tribunal decides the relationship was really employment, you could face:

- **Back taxes and National Insurance**, potentially with interest and penalties.
- **Claims for employment rights** such as holiday pay or unfair dismissal.
- **Reputational and operational disruption**.

The safest approach is to assess each engagement honestly against the real factors — control, personal service, mutuality of obligation and financial risk — rather than choosing the label that is cheapest. GOV.UK's Check Employment Status for Tax (CEST) tool and guidance can help, and Acas offers support on the employment side. For anything significant, take professional advice.

## The bottom line

The difference between a contractor and an employee is not a matter of preference or paperwork — it is determined by how the work is actually done, and it shapes rights, tax, cost and control. Contractors bring flexibility and specialist skill for projects and fluctuating needs; employees bring continuity, control and commitment for core roles. Choose based on the genuine nature of the work, document it accurately, and never assume a label alone protects you. *This is general information, not legal or tax advice; check GOV.UK and take professional guidance for your circumstances.*

## Frequently asked questions

### What is the difference between a contractor and an employee?

An employee works under a contract of employment, has statutory employment rights, and is taxed through PAYE with the employer deducting tax and National Insurance. A contractor is self-employed or works through their own company, takes on financial risk, usually works for multiple clients, and is responsible for their own tax. This is general information, not legal advice.

### Can I just call someone a contractor to save on costs?

No. Employment status is decided by the reality of the working relationship, not by the label on a contract or the fact that someone invoices you. If a 'contractor' is actually working as an employee, you can face claims for unpaid tax, National Insurance and employment rights. Assess each role honestly and take advice.

### Do contractors get holiday pay and sick pay?

Genuine self-employed contractors do not receive employee benefits such as paid holiday, statutory sick pay or pension contributions from the client. However, some individuals qualify as 'workers' — a middle category that does carry certain rights, including paid holiday. Status can be nuanced, so check the specific arrangement.

### When should a business use a contractor instead of an employee?

Contractors generally suit short-term projects, specialist skills you need occasionally, fluctuating workloads, or work that does not require deep integration into your team. Ongoing, core roles that need control, continuity and commitment usually point towards employing someone instead.
