Self-Employed vs Employed in the UK

Self-Employed vs Employed: Why It Matters

One of the most common tax questions in the UK is whether someone is self-employed or employed. It sounds simple, but for HMRC, the answer is not based only on what a contract says. It depends on the actual working arrangement.

This distinction matters because it affects:

• who pays Income Tax and National Insurance,

• whether PAYE should be operated,

• whether allowable expenses can be claimed,

• whether CIS may apply in construction,

• and whether there is a risk of HMRC challenging the arrangement.

  
  

For business owners, getting employment status wrong can create unexpected tax bills, interest, penalties and payroll problems. For workers, it can affect take-home pay, record keeping and tax responsibilities.

What Is the Difference Between Self-Employed and Employed?

In simple terms:

• An employee usually works under the control of an employer, is paid through PAYE, and has tax and National Insurance deducted before receiving pay.

• A self-employed person usually runs their own business, invoices for work, manages their own tax through Self Assessment, and takes more financial responsibility and commercial risk.

However, real-life arrangements are not always straightforward. Someone can be called “self-employed” in a contract, but HMRC may still view them as employed if the facts point that way.

How HMRC Decides Employment Status

HMRC looks at the full picture of the working relationship. There is no single test, but some of the main factors include:

Control

Who decides what work is done, when it is done, where it is done, and how it is done?

The more control the engager has, the more likely the worker is to be treated as employed.

Personal service

Does the individual have to do the work personally, or can they send someone else to do it?

If the worker must provide the service themselves, that can point more towards employment.

Financial risk

Does the worker risk making a loss, pay to fix mistakes, provide their own tools or materials, or have the chance to increase profit by working efficiently?

Greater financial risk is more consistent with self-employment.

Working for yourself

Is the person genuinely in business on their own account?

For example, do they market their services, work for multiple clients, set their own prices, and invoice directly?

What happens in practice

HMRC does not just look at the written contract. It also considers the day-to-day reality. If the actual arrangement is different from the paperwork, HMRC will focus on what is really happening.

Construction: Why CIS Does Not Automatically Mean Self-Employment

Construction is one of the biggest areas of confusion. Many workers assume that if they are paid under the Construction Industry Scheme (CIS), they must be self-employed. That is not necessarily true.

CIS is a tax deduction system for certain payments in the construction industry. It does not by itself decide employment status. A worker can still be treated as employed if the real working arrangement points that way.

Why this matters

If a construction business gets this wrong, it can lead to payroll risk, HMRC challenges and underpaid tax liabilities.

Why Professional Advice Matters

Employment status is one of those areas where small details can make a big difference. The tax consequences of getting it wrong can be significant, especially where multiple workers are involved.

Professional advice can help you:

• review current contracts and working practices,

• identify HMRC risk areas,

• decide whether PAYE should apply,

• understand CIS interaction,

• improve record keeping and compliance,

• protect your business before problems escalate.
